How to Reduce Taxable Income for High Earners in Arizona (2026)
If you're a high earner in Arizona, your tax bill is shaped by three layers at once: federal ordinary income tax, the 3.8% Net Investment Income Tax on top of that if you have investment income, and Arizona's flat state income tax. The good news is that federal and state law both offer legal, well-established ways to lower what's actually taxable, not just defer paperwork. Here are 12 strategies that matter most for Arizona small-business owners, real estate investors, and high earners heading into 2026.
Key Takeaways
- You can defer $24,500 into a 401(k) in 2026, plus a $8,000 catch-up if you're 50+, or $11,250 if you're 60-63, according to the IRS.
- The Qualified Business Income deduction is now permanent under the One Big Beautiful Bill Act (OBBBA) and the phase-in ranges widened for 2026, per the IRS.
- The federal SALT deduction cap rose to $40,400 for 2026, but it phases down once your MAGI passes roughly $505,000.
- Arizona's Pass-Through Entity election lets business owners pay state tax at the entity level (2.5%), working around the individual SALT cap entirely, according to ADOR.
- Real estate investors can defer capital gains tax indefinitely through 1031 like-kind exchanges, per IRS rules.
1. Max out retirement plan contributions
The most direct way to reduce taxable income is to defer more of it. For 2026, the IRS raised the 401(k), 403(b), and governmental 457 contribution limit to $24,500. If you're 50 or older, you can add a $8,000 catch-up contribution. If you're 60 to 63, SECURE 2.0's enhanced catch-up lets you add $11,250 instead. That's up to $35,750 in pre-tax deferrals for someone in that age bracket.
One wrinkle for 2026: if you earned more than $150,000 in 2025, your catch-up contributions must go into the plan as Roth (after-tax) dollars rather than pre-tax. That doesn't reduce this year's taxable income, but it still builds a valuable long-term Roth savings pool.
2. Use a backdoor or mega backdoor Roth
If your income is too high to contribute directly to a Roth IRA, an IRS-sanctioned backdoor Roth conversion still works: contribute to a traditional IRA (nondeductible, since you're over the income limit), then convert it to a Roth. For 2026, the Roth IRA phase-out range is $153,000 to $168,000 for single filers and $242,000 to $252,000 for married filing jointly.
If your 401(k) plan allows after-tax contributions beyond the standard deferral limit, a mega backdoor Roth lets you contribute up to $72,000 total (employee plus employer plus after-tax) in 2026, then roll the after-tax portion into a Roth account. This doesn't reduce this year's taxable income directly, but it builds tax-free growth that keeps future withdrawals off your tax return entirely.
3. Max out your HSA if you have a qualifying health plan
If you're enrolled in a high-deductible health plan, an HSA is one of the only accounts that's triple tax-advantaged: contributions are deductible, growth is tax-free, and qualified withdrawals are tax-free. For 2026, the limit is $4,400 for self-only coverage and $8,750 for family coverage, with an additional $1,000 catch-up if you're 55 or older, per the IRS's 2026 inflation adjustments for HSAs.
4. Consider an S-corp election if you're self-employed
If you operate as a sole proprietor or single-member LLC, all your net profit is subject to 15.3% self-employment tax. Electing S-corp taxation lets you split income between a reasonable W-2 salary (subject to payroll tax) and distributions (which aren't). For business owners with consistent profit well above what a reasonable salary would be, this can mean real savings, though it adds payroll costs and administrative complexity. Our Strategic Tax Advisory team can model whether the math works for your specific numbers.
5. Optimize the Qualified Business Income deduction
The QBI deduction lets eligible owners of sole proprietorships, partnerships, S-corps, and certain trusts deduct up to 20% of qualified business income, according to the IRS. Under OBBBA, this deduction is now permanent rather than expiring after 2025, and the phase-in ranges for high earners widened for 2026: from $100,000 to $150,000 above the threshold for joint filers, and from $50,000 to $75,000 for other filers. If you're a specified service business (law, consulting, health care, and similar fields) close to the old thresholds, it's worth re-running the numbers for 2026, since more income now qualifies. This is one of several reasons high earners tend to overpay without a proactive review each year.
6. Use Arizona's Pass-Through Entity election
Arizona lets partnerships and S-corps elect to pay state income tax at the entity level instead of passing it through to individual owners. For 2025, that rate is 2.5%, according to ADOR Publication 713. Because the entity pays the tax (and deducts it as a business expense on the federal return), this effectively works around the federal cap on individual state and local tax deductions. Any unused PTE credit carries forward for up to five years. Partners or shareholders who are individuals, estates, or trusts can opt out if it doesn't make sense for their situation.
7. Plan around the SALT deduction cap and its phase-out
The federal cap on state and local tax deductions rose from $10,000 to $40,000 for 2025 and increases roughly 1% a year through 2029, landing at $40,400 for 2026. But the increased cap phases down once your modified adjusted gross income passes about $500,000 (2025) or $505,000 (2026), and it disappears entirely, reverting to the $10,000 floor, once MAGI hits roughly $600,000. If your income puts you in that phase-out band, strategies like deferring income, harvesting capital losses, or maximizing retirement and HSA contributions can pull your MAGI back under the threshold and preserve more of the deduction.
8. Stack charitable giving strategically
Rather than giving the same amount every year, "bunching" multiple years of charitable contributions into a single tax year (often through a donor-advised fund) can push you over the itemization threshold in that year, while you take the standard deduction in others. If you're 70½ or older, a Qualified Charitable Distribution lets you send up to your RMD amount directly from an IRA to charity, which counts toward your required minimum distribution without ever hitting your adjusted gross income.
Arizona layers its own dollar-for-dollar credits on top of federal giving. For 2026, the maximum credit for donations to Qualifying Charitable Organizations is $506 single or $1,009 married filing jointly, and for Qualifying Foster Care Charitable Organizations it's $632 single or $1,262 married filing jointly, according to ADOR. These are credits, not deductions, so they reduce your Arizona tax bill dollar for dollar, and they stack with the Arizona private school and public school tax credits. Our Estate Planning, Trust & Entity Formation team can help structure larger charitable strategies alongside your broader estate plan.
9. Use a 1031 exchange to defer capital gains on real estate
For real estate investors, Section 1031 of the tax code allows you to sell business or investment real property and reinvest the proceeds into other "like-kind" real property without recognizing the gain in the year of sale, according to the IRS. Since the Tax Cuts and Jobs Act, this only applies to real property, not personal or intangible property. You have 45 days to identify replacement property and 180 days to close, and the funds must pass through a qualified intermediary rather than touching your hands directly. Done correctly, an investor can roll gains from one property into the next indefinitely, deferring tax until an eventual sale that isn't reinvested.
10. Use bonus depreciation and cost segregation on real estate and equipment
OBBBA restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025, reversing the phase-down that had been reducing it toward zero, according to IRS guidance issued under the One Big Beautiful Bill. For real estate investors, pairing this with a cost segregation study, which reclassifies parts of a building into shorter depreciation categories, can front-load a substantial deduction in the year a property is placed in service rather than spreading it over 27.5 or 39 years.
11. Manage capital gains timing and harvest losses
Long-term capital gains (assets held over a year) are taxed at preferential federal rates well below ordinary income rates, and timing matters. Selling appreciated assets in a lower-income year, spreading a large gain across multiple tax years, or harvesting losses elsewhere in your portfolio to offset gains can all reduce what actually shows up as taxable income. This matters even more once you're near the Net Investment Income Tax threshold: the IRS applies a 3.8% surtax on investment income once modified AGI exceeds $200,000 for single filers or $250,000 for married filing jointly, on top of regular capital gains tax.
12. Consider a Cash Balance or defined benefit plan
For business owners with consistent, healthy profit who've already maxed out a 401(k), a Cash Balance plan allows substantially larger annual contributions, often well over $100,000 depending on age and income, all fully deductible to the business. These plans require actuarial calculations and a real commitment to funding them for several years, so they work best for established businesses with stable cash flow. Our Accounting & Business Performance team can help determine whether your business's numbers support one.
Putting it together
No single strategy on this list does all the work. The right combination depends on whether your income is primarily wages, business profit, or investment gains, whether you're itemizing or taking the standard deduction, and how close you are to thresholds like the SALT phase-out or the NIIT trigger. A plan built in isolation from your bookkeeping and entity structure tends to leave money on the table or, worse, create documentation gaps that don't hold up if the IRS asks questions.

Frequently Asked Questions
What's the single most effective way to reduce taxable income as a high earner?
There isn't one universal answer. For W-2 employees, maximizing retirement plan contributions is usually the biggest lever available. For business owners, the combination of entity structure (S-corp election), the QBI deduction, and retirement plan design (including Cash Balance plans) typically has more impact than any single move.
Does Arizona have its own version of tax-advantaged retirement accounts?
No. Arizona follows federal rules for retirement account contribution limits and tax treatment. Where Arizona adds value is through its own credits, particularly the Pass-Through Entity election and the dollar-for-dollar charitable tax credits, which stack on top of federal strategies.
Is the backdoor Roth IRA actually legal?
Yes. It's a well-established, IRS-recognized combination of two legal transactions: a nondeductible traditional IRA contribution followed by a Roth conversion. There's no dollar limit on conversions the way there is on direct Roth contributions, though you'll want to understand the pro-rata rule if you hold other pre-tax IRA funds.
How does the SALT cap phase-out actually affect my Arizona and federal tax bill?
It affects only your federal itemized deduction for state and local taxes, not what you owe Arizona directly. If your MAGI is in the phase-out band, less of your Arizona income tax and property tax becomes federally deductible, which effectively raises your federal taxable income even though your state tax bill didn't change.
Can I use a 1031 exchange on a property I live in part-time?
Generally no. Section 1031 applies to property held for business use or investment, not primarily for personal use. Vacation homes and primary residences typically don't qualify unless they meet specific investment-use tests, which is worth discussing with a tax professional before relying on this strategy.
Do I need to itemize to benefit from any of these strategies?
No. Retirement contributions, HSA contributions, the QBI deduction, and the Arizona PTE election all work regardless of whether you itemize or take the standard deduction. Only the SALT deduction and the charitable bunching strategy require itemizing to have an effect.
