As tax season approaches, the question of whether to itemize or take the standard deduction is a critical decision point for millions of taxpayers. While the standard deduction offers simplicity, itemizing can unlock substantial savings, particularly for homeowners, investors, and high-income earners. The Tax Cuts and Jobs Act (TCJA) of 2017 significantly increased the standard deduction, making it the better choice for many. However, for those with significant qualifying expenses, a strategic approach to itemization can reduce taxable income far more effectively.
This guide provides a comprehensive roundup of the most common itemized deductions, exploring who qualifies, the specific rules and limitations, and the documentation required to claim them confidently. We'll delve into recent law changes, like the State and Local Tax (SALT) cap, and provide actionable insights to help you, as an Allied Tax Advisors client, determine the most advantageous path forward for your unique financial situation.
The key to maximizing your tax benefits through itemization is meticulous record-keeping. You must be able to substantiate every deduction you claim with clear, organized documentation. To confidently choose to itemize and efficiently substantiate your claims, robust record-keeping is crucial, and dedicated platforms like ReceiptMake can streamline this process. Understanding these rules is the first step toward building a tax strategy that aligns with your financial goals and minimizes your liability. Let's explore the deductions that could make a significant difference on your next tax return.
1. Mortgage Interest Deduction
For many homeowners, the mortgage interest deduction is one of the most significant common itemized deductions available, often making the difference between taking the standard deduction and itemizing. This deduction allows taxpayers to subtract the interest paid on home loans for their primary or secondary residence from their taxable income, directly reducing their tax liability. It's a key tax benefit designed to make homeownership more affordable.
Who Qualifies and What are the Limits?
To qualify, the loan must be a secured debt on a qualified home, meaning your primary or a second home. The Tax Cuts and Jobs Act of 2017 introduced new limits. For mortgages taken out after December 15, 2017, you can only deduct interest on up to $750,000 of mortgage debt ($375,000 if married filing separately). Mortgages originated before this date are generally grandfathered under the previous $1 million limit.
This deduction also extends to real estate investors who can deduct mortgage interest on rental properties as a business expense on Schedule E, separate from their personal itemized deductions.
Real-World Scenarios
- Primary Homeowner: A San Diego resident with a new $600,000 mortgage at 6% interest could deduct approximately $35,800 in interest in the first full year.
- Rental Property Investor: An investor with a $500,000 mortgage on a rental property can deduct the full interest amount as a rental expense, reducing the property's taxable income.
Actionable Tips for Maximizing Your Deduction
- Documentation is Key: At the end of the year, your lender will send you Form 1098, which reports the total mortgage interest you paid. Keep this form with your tax records.
- Track Your Points: Mortgage points, a form of prepaid interest, can also be deductible. You can learn more about deducting mortgage points to see if you qualify.
- Strategic Financing: For real estate investors, structuring financing across multiple properties can maximize tax benefits. It’s crucial to maintain clear records that distinguish interest paid on your personal residence versus your investment properties.
- Consult an Expert: The rules for home equity debt and investment properties can be complex. Work with your Allied Tax Advisors CPA to model different financing scenarios and ensure you are correctly claiming all allowable interest.
2. Property Tax Deduction (SALT Cap)
The deduction for state and local taxes, commonly known as the SALT deduction, is one of the most widely used common itemized deductions. It allows taxpayers to deduct certain taxes paid to state and local governments, including property, income, and sales taxes. However, the Tax Cuts and Jobs Act of 2017 (TCJA) introduced a significant limitation, capping the total SALT deduction at $10,000 per household ($5,000 for those married filing separately), which has major implications, especially for residents of high-tax states.
Who Qualifies and What are the Limits?
Taxpayers who choose to itemize can deduct a combination of state and local property taxes and either state and local income taxes or sales taxes. The total amount you can claim is subject to the $10,000 annual cap. This cap applies to the combined total of all these taxes. It's important to note this limit does not apply to property taxes paid on business or rental properties; those are fully deductible as business expenses on the appropriate schedules (like Schedule C or E).
This cap, currently extended through 2025, forces many taxpayers in states like California to make strategic decisions about which taxes to prioritize for their personal deduction.
Real-World Scenarios
- San Diego Real Estate Investor: An investor with $12,000 in personal property taxes and $8,000 in state income taxes can only deduct a total of $10,000 on their Schedule A, losing out on a potential $10,000 deduction.
- High-Income Professional: A California professional earning $250,000 may pay well over $15,000 in state income tax alone but is limited to claiming just $10,000 under the SALT cap.
- Rental Property Owner: An individual with multiple rental properties in California must deduct the property taxes for those rentals on Schedule E. They can then use their remaining personal property and state income taxes toward the $10,000 personal SALT deduction cap.
Actionable Tips for Maximizing Your Deduction
- Separate Business from Personal: Keep meticulous records distinguishing property taxes paid for your personal residence (subject to the SALT cap) from those paid for investment properties (fully deductible as a business expense).
- Strategic Payment Timing: If your income fluctuates, consider timing large state income or property tax payments to optimize your deductions across multiple years, especially if you alternate between itemizing and taking the standard deduction.
- Monitor Legislation: The $10,000 SALT cap is a hot topic in tax law and is set to expire after 2025. Stay informed about potential changes that could impact your tax planning. You can learn more about the deductibility of state taxes and how the rules apply.
- Consult an Expert: The interaction between personal and business property taxes, especially for real estate investors and S Corp owners, requires careful planning. Work with your Allied Tax Advisors CPA to model scenarios and ensure you are structuring your deductions for maximum tax benefit.
3. Charitable Contributions Deduction
Supporting causes you care about can also provide a significant tax benefit, making charitable contributions one of the most popular common itemized deductions. Taxpayers who itemize can deduct donations made to qualified charitable organizations, including cash, property, and even appreciated securities. This powerful deduction allows you to reduce your taxable income while making a positive impact.
Who Qualifies and What are the Limits?
To be deductible, your contribution must be made to a qualified 501(c)(3) organization. The deduction limit for cash contributions is generally up to 60% of your adjusted gross income (AGI). For donations of non-cash assets like stocks or real estate, the limits are typically lower, often 30% of AGI. Any contributions that exceed these AGI limits in a given year can usually be carried forward and deducted for up to five subsequent years.
Beyond general contributions, exploring sophisticated charitable giving tax strategies can help you maximize your philanthropic impact while also benefiting from deductions.
Real-World Scenarios
- Appreciated Assets: A San Diego business owner donates company stock valued at $50,000 to a local university. By donating the stock directly, they can claim the full $50,000 deduction and avoid paying capital gains tax on the appreciation.
- Strategic Gifting: A high-income individual "bunches" three years of planned donations into a single year by contributing to a donor-advised fund. This allows them to exceed the standard deduction threshold for that year, maximizing their tax benefit.
Actionable Tips for Maximizing Your Deduction
- Maintain Meticulous Records: Keep detailed records for all donations, including bank statements or canceled checks for cash gifts and written acknowledgments from the charity for any contribution of $250 or more.
- Consider Donating Securities: Gifting appreciated securities held for more than one year is often more tax-efficient than donating cash. You can deduct the full fair market value and bypass capital gains tax.
- Get an Appraisal: For non-cash donations valued over $5,000, such as art or real estate, you must obtain a qualified appraisal to support your deduction.
- Coordinate with Your Advisor: Work with your Allied Tax Advisors CPA to align your charitable giving with your overall investment and tax planning strategy, ensuring you get the maximum benefit from your generosity.
4. Rental Property Deductions
For real estate investors, rental property deductions are not just beneficial; they are essential for accurately calculating taxable income and maximizing returns. Unlike many personal expenses, costs associated with owning and managing a rental property are considered business expenses. This allows investors to deduct a wide range of costs from their gross rental income, significantly reducing their tax liability. These are distinct from common itemized deductions reported on Schedule A and are instead claimed on Schedule E (Supplemental Income and Loss).
Who Qualifies and What Can Be Deducted?
Anyone who owns and rents out a property qualifies to deduct the associated ordinary and necessary expenses. This includes everything from single-family homes to multi-unit apartment buildings. The list of deductible expenses is extensive and includes mortgage interest, property taxes, insurance, maintenance and repairs, utilities paid by the owner, property management fees, and advertising costs.
A key deduction unique to real estate is depreciation, which allows investors to deduct a portion of the property's cost (the building, not the land) over 27.5 years for residential properties. This non-cash expense can create a significant tax shield.
Real-World Scenarios
- San Diego Investor: An investor in San Diego earns $80,000 in annual rent. After deducting $20,000 in mortgage interest, $8,000 in property taxes, $5,000 for maintenance, and $15,000 in depreciation, their taxable income is reduced to just $32,000.
- Repairs vs. Improvements: A landlord spends $3,000 fixing a leaky faucet and patching drywall, which is fully deductible as a repair in the current year. They also spend $8,000 replacing the entire roof, which is a capital improvement that must be capitalized and depreciated over 27.5 years.
Actionable Tips for Maximizing Your Deduction
- Meticulous Record-Keeping: Use business accounting software like QuickBooks and a separate business bank account for each property. This creates a clean audit trail and simplifies tax preparation.
- Distinguish Repairs from Improvements: Document all work with photos, detailed invoices, and descriptions. Misclassifying a capital improvement as a repair is a common IRS audit trigger.
- Master Depreciation: Maintain detailed depreciation schedules for each property and its major improvements. A cost segregation study can accelerate depreciation deductions on certain components of a building, providing significant upfront tax savings.
- Explore Real Estate Professional Status: If you meet specific criteria, qualifying as a Real Estate Professional can allow you to deduct rental losses against your other ordinary income, a powerful tax-saving strategy. Allied Tax Advisors can help determine if you qualify and ensure you maintain the required documentation.
5. Business Expense Deductions (Self-Employed)
For self-employed individuals, freelancers, and small business owners, deducting business expenses is not just one of the most impactful common itemized deductions; it's a fundamental aspect of accurately calculating taxable income. This allows you to subtract ordinary and necessary business costs from your gross income, ensuring you are taxed only on your actual profit. These deductions are typically reported on Schedule C (Form 1040), directly lowering both your income tax and self-employment tax liabilities.
Who Qualifies and What are the Limits?
Any individual operating as a sole proprietor, independent contractor, or single-member LLC qualifies to deduct business expenses. The core rule is that an expense must be both ordinary (common and accepted in your trade or business) and necessary (helpful and appropriate for your business). While there aren't specific dollar limits on most categories, the expenses must be reasonable in amount.
Key deductible categories include home office expenses, vehicle mileage, professional services, software, and supplies. Proper record-keeping is crucial, as the IRS requires documentation to substantiate these claims.
Real-World Scenarios
- San Diego Consultant: A consultant with $150,000 in revenue deducts a $6,000 home office (based on actual expenses), $4,000 in vehicle mileage for client visits, and $8,000 for professional services, reducing their taxable income to $132,000.
- Freelance Accountant: An accountant deducts $10,000 for specialized tax software, $5,000 for continuing education courses, and $8,000 for new computer equipment, significantly lowering their self-employment tax burden.
Actionable Tips for Maximizing Your Deduction
- Maintain Contemporaneous Records: Don't wait until tax time to organize. Keep a detailed, real-time mileage log with the date, purpose, and miles for each business trip. Save receipts and invoices for all purchases, noting their business purpose.
- Separate Your Finances: Open a dedicated business checking account and use it exclusively for business income and expenses. This simplifies bookkeeping and provides a clear audit trail.
- Document Your Home Office: To claim the home office deduction, ensure the space is used exclusively and regularly for business. Measure the square footage and keep records of associated costs like utilities, insurance, and repairs.
- Quarterly Reviews: Work with your CPA to review your business expense categories each quarter. This helps identify overlooked deductions and ensures you are on track with your estimated tax payments. Allied Tax Advisors can assist with proactive bookkeeping and planning to optimize these deductions.
6. Medical and Dental Expenses Deduction
For taxpayers with significant healthcare costs, the medical and dental expense deduction is one of the most valuable common itemized deductions. It allows you to deduct the amount of qualified medical care expenses that exceeds 7.5% of your adjusted gross income (AGI). This high AGI threshold makes it a less common deduction, but it provides substantial relief for those facing high out-of-pocket costs due to chronic illness, major surgery, or long-term care needs.
Who Qualifies and What are the Limits?
You can deduct qualified medical expenses you paid for yourself, your spouse, and your dependents. The key hurdle is the 7.5% AGI floor, meaning only expenses above this amount are deductible. For example, if your AGI is $100,000, your threshold is $7,500. If you had $12,000 in eligible medical expenses, you could deduct $4,500.
Eligible expenses are broad and include payments for doctor and dentist visits, hospital care, prescription drugs, medical equipment like glasses or hearing aids, and even travel costs for essential medical care. Premiums for health insurance are also deductible if paid with post-tax dollars.
Real-World Scenarios
- Taxpayer with High Expenses: A taxpayer with an AGI of $100,000 and $10,000 in medical bills (for surgery and prescriptions) would first calculate their threshold ($100,000 x 7.5% = $7,500). They could then deduct the excess amount of $2,500.
- Caring for an Aging Parent: A San Diego resident caring for their elderly parent can include the parent's medical expenses (like nursing care and medications) in their own calculation, provided they meet dependency rules. This often helps them surpass the 7.5% AGI threshold.
Actionable Tips for Maximizing Your Deduction
- Aggregate and Track Everything: Keep meticulous records of all medical payments throughout the year, including co-pays, prescriptions, and dental work. Every small expense adds up and helps you meet the threshold.
- Track Medical Mileage: Don't forget to track your mileage to and from medical appointments. You can deduct these miles at the standard IRS rate for medical travel, which adds to your total deductible expenses.
- Strategic Timing: If possible, consider bundling discretionary medical procedures (like dental work or new glasses) into a single year where you anticipate high medical costs. This "bunching" strategy can help you exceed the 7.5% floor.
- Maintain Documentation: Always keep itemized receipts, doctor's statements, and Explanation of Benefits (EOB) forms from your insurer. This documentation is crucial for substantiating your claims in case of an audit. Your Allied Tax Advisors professional can help review your records to ensure every eligible expense is captured.
7. Depreciation and Cost Segregation for Real Estate
For real estate investors, depreciation is one of the most powerful common itemized deductions, representing a non-cash expense that can significantly reduce taxable rental income. This deduction allows investors to recover the cost of a building and its improvements over a set period. It's a critical tool for maximizing after-tax returns from investment properties.
Who Qualifies and What are the Limits?
Investors who own income-producing property can claim depreciation. The IRS sets the recovery period for residential rental property at 27.5 years and for commercial property at 39 years. Land itself cannot be depreciated. A technique called a cost segregation study can accelerate these deductions by identifying parts of the property, like carpeting or specialized electrical systems, that can be depreciated over shorter periods (5, 7, or 15 years) instead of the standard building life.
This strategy dramatically increases deductions in the early years of ownership, improving cash flow and providing capital for further investment.
Real-World Scenarios
- Standard Depreciation: A San Diego investor buys a $1,000,000 rental home. With the land valued at $200,000, the $800,000 building provides an annual depreciation deduction of approximately $29,090 ($800,000 / 27.5 years).
- Cost Segregation: A commercial real estate investor conducts a study on a new $5,000,000 building, identifying $1,200,000 in personal property and land improvements. This can increase the first-year deduction from around $128,205 to over $380,000.
Actionable Tips for Maximizing Your Deduction
- Timing is Everything: Conduct a cost segregation study within the first few years of acquiring a property to maximize the time-value benefit of the accelerated deductions.
- Track Improvements: Keep detailed records of all capital improvements, as each one adds to your depreciable basis and can be written off over its own useful life.
- Plan for Recapture: When you sell a property, the accumulated depreciation is "recaptured" and taxed. Plan for this event or consider strategies like a 1031 exchange to defer the tax.
- Consult an Expert: Cost segregation is a complex engineering and tax strategy. Work with Allied Tax Advisors to determine if a study is right for your portfolio and to understand the full benefits of a cost segregation study for your specific properties.
8. Education and Skill-Development Expenses
While many popular education tax credits were eliminated for individuals, self-employed taxpayers can still leverage skill development as a powerful business expense. This deduction allows self-employed individuals to subtract the costs of qualifying education that maintains or improves skills required in their existing trade or business. It's a key strategy for professionals who must engage in continuing education to stay current or maintain licensure.
Who Qualifies and What are the Limits?
This deduction is primarily for self-employed individuals who report income on Schedule C. The education must be directly related to their current business; it cannot be to qualify for a new trade or business. For example, an attorney taking a tax law seminar can deduct the cost, but that same attorney cannot deduct the cost of an MBA program that would qualify them for a new profession in finance.
There is no specific dollar limit, but the expenses must be considered "ordinary and necessary" for the business. Deductible costs include tuition, books, supplies, fees, and even travel related to the educational activity.
Real-World Scenarios
- Licensed Professional: A San Diego accountant deducts $2,000 for CPA continuing education courses required to maintain their professional license.
- Skilled Tradesperson: A software developer deducts $1,500 for a certification course in a new programming language to enhance their current development skills.
- Consultant: An independent marketing consultant deducts the $3,000 cost of a digital advertising seminar to improve services offered to existing clients.
Actionable Tips for Maximizing Your Deduction
- Classify as a Business Expense: Self-employed individuals should report these costs directly on Schedule C, not as an itemized deduction on Schedule A. This makes it an "above-the-line" deduction that reduces your adjusted gross income (AGI).
- Thorough Documentation: Keep detailed records, including course descriptions, certificates of completion, invoices, and receipts. For professional licenses, retain documents showing the specific educational requirements for maintenance.
- Don't Forget Related Costs: If you travel for a qualifying conference or seminar, you can deduct the costs of transportation, lodging, and 50% of your meals.
- Document the "Why": Be prepared to justify that the education maintains or improves existing skills, rather than qualifying you for a new profession. Keep curriculum materials to support your claim if the IRS ever questions the purpose of the deduction.
9. Investment Interest Expense Deduction
For active investors who use leverage to fund their portfolios, the investment interest expense deduction is one of the most valuable common itemized deductions. This allows taxpayers to deduct the interest paid on money borrowed to purchase or carry investments, such as stocks, bonds, or investment land. The deduction directly offsets investment income, reducing your overall tax burden on investment returns.
Who Qualifies and What are the Limits?
This deduction is available to taxpayers who borrow money to make investments and pay interest on that loan. This includes margin loans from a brokerage account or a separate loan used to buy stocks or bonds. The key limitation is that you can only deduct investment interest expense up to the amount of your net investment income for the year. Any excess interest that you can't deduct in the current year can be carried forward indefinitely to future years.
Net investment income includes interest, non-qualified dividends, annuities, and royalties. It can also include net short-term and long-term capital gains, but you must elect to treat them as investment income, which means they won't be taxed at the lower long-term capital gains rates.
Real-World Scenarios
- Margin Loan User: A San Diego investor uses a $200,000 margin loan at 5% interest to purchase a stock portfolio. They pay $10,000 in margin interest and earn $8,000 in dividend income. They can deduct $8,000 of the interest expense, and the remaining $2,000 is carried forward to the next tax year.
- Balancing Gains and Interest: An investor has $40,000 in long-term capital gains and $30,000 in dividend income, creating a net investment income of $70,000. If they paid $60,000 in investment interest, they could deduct the full amount.
Actionable Tips for Maximizing Your Deduction
- Segregate Your Loans: Do not co-mingle funds from investment loans with personal use funds. Maintain a separate account and clear documentation showing the loan proceeds were used directly for investment purposes.
- Track Net Investment Income: Diligently track all sources of investment income, including interest, dividends, and capital gains. This figure is the ceiling for your annual deduction.
- Time Your Gains and Losses: If you have significant investment interest, consider recognizing capital gains to increase your net investment income, which allows you to use more of the deduction.
- Consult an Expert: The rules for calculating net investment income and carrying forward unused interest can be complex. Your Allied Tax Advisors CPA can help you strategize the timing of income recognition and ensure you properly document and claim this powerful deduction.
10. Gambling and Casino Loss Deduction
For individuals who enjoy games of chance, the gambling loss deduction is a unique and often overlooked itemized deduction. This provision allows taxpayers to deduct gambling losses, but with a critical caveat: the deduction is limited to the amount of gambling winnings reported as income for the same year. This makes it one of the more specialized common itemized deductions, as it cannot be used to create a net loss to offset other income.
Who Qualifies and What are the Limits?
Any taxpayer who itemizes their deductions on Schedule A can claim this deduction. The rule is straightforward: you can deduct losses from activities like casino games, sports betting, lotteries, and horse racing, but only up to the amount of your reported winnings. For instance, if you win $5,000 but have losses totaling $6,000, your deduction is capped at $5,000, and the extra $1,000 loss provides no tax benefit.
It's important to note that you cannot simply subtract your losses from your winnings and report the net amount. You must report all your winnings as "Other Income" on your tax return and then separately claim your allowable losses as an itemized deduction.
Real-World Scenarios
- Casual Casino Player: A visitor to Las Vegas wins $5,000 from slot machines but has documented losses of $3,500 from other games. They must report the full $5,000 as income and can then deduct $3,500 in losses, resulting in a net taxable income of $1,500 from gambling.
- Sports Bettor: An online sports bettor has a successful year with $8,000 in winnings but also incurs $9,000 in losses on other wagers. They can deduct only $8,000 of the losses to completely offset their winnings, leaving them with no taxable gambling income. The remaining $1,000 loss cannot be carried forward or used to offset other income.
Actionable Tips for Maximizing Your Deduction
- Keep a Detailed Diary: The IRS requires meticulous records. Maintain a log or journal with the date, location, type of wagering activity, and the specific amounts you won or lost during each session.
- Collect All Proof: Save wagering tickets, receipts, Form W-2G, casino statements, and bank records showing deposits and withdrawals. This documentation is your primary defense in an audit.
- Don't Net Your Results: Always report your gross winnings and losses separately on your tax return. Netting them on your own is an incorrect reporting method that can trigger IRS scrutiny.
- Consult an Expert: The rules for professional gamblers differ significantly, as they may be able to treat losses as business expenses. If you have substantial gambling activity, your Allied Tax Advisors CPA can help ensure you have the proper documentation and are claiming deductions correctly.

Partnering for Precision: When to Consult Allied Tax Advisors
Navigating the landscape of common itemized deductions is far more than an end-of-year scramble to gather receipts. It's a strategic process of financial planning, careful record-keeping, and understanding how each deductible expense interacts with your unique financial profile. As we've explored, from the intricacies of the mortgage interest deduction and the SALT cap to the specialized rules for medical expenses and charitable contributions, the decision to itemize versus taking the standard deduction is a critical one with significant financial implications.
The standard deduction provides a straightforward, no-questions-asked reduction in your taxable income. However, for many taxpayers, particularly homeowners, entrepreneurs, real estate investors, and those with substantial medical costs or charitable giving, simply taking the standard deduction can mean leaving thousands of dollars on the table. The true power lies in evaluating whether your total qualifying expenses, meticulously tracked and documented, surpass that standard threshold.
From Record-Keeping to Strategic Tax Planning
Mastering itemized deductions transforms tax preparation from a reactive chore into a proactive strategy. It requires a forward-thinking mindset throughout the year. For instance, understanding the Adjusted Gross Income (AGI) limitations on medical expenses or charitable gifts allows you to plan the timing of these expenditures. Similarly, knowing the documentation requirements for business use of a vehicle or non-cash donations ensures you are audit-proof long before a tax return is ever filed.
The key takeaways from our comprehensive listicle are clear:
- Documentation is Paramount: The IRS requires detailed, contemporaneous records for most deductions. A well-organized system for tracking receipts, mileage logs, and donation acknowledgments is your first line of defense.
- Thresholds and Limits Matter: Many deductions, like medical expenses and casualty losses, are subject to AGI floors, meaning you can only deduct the amount that exceeds a certain percentage of your income. Caps, like the $10,000 SALT limit, also directly impact your total itemized amount.
- Life Events Trigger Tax Opportunities: A new home purchase, a significant medical diagnosis, starting a business, or inheriting investments can dramatically shift your deduction landscape. Recognizing these moments as tax-planning opportunities is crucial.
Why Expert Guidance Makes the Difference
While understanding the rules is the first step, applying them strategically is where professional guidance becomes invaluable. For our clients at Allied Tax Advisors, the conversation about common itemized deductions goes beyond simple compliance. It's about optimization.
For a real estate investor, it might involve a cost segregation study to accelerate depreciation and maximize immediate deductions. For a high-income earner, it could mean "bunching" multiple years of charitable contributions into a single year using a Donor-Advised Fund to easily surpass the standard deduction. For a small business owner, it involves ensuring every legitimate business expense is captured and categorized correctly to reduce both income and self-employment taxes.
These strategies aren't found in standard tax software; they are born from experience, expertise, and a deep understanding of a client's complete financial picture. Our role is to analyze your situation, identify every potential deduction you are legally entitled to, and build a tax plan that supports your long-term goals. Don't let complexity prevent you from achieving significant tax savings.
