The tax implications of selling a business in Arizona improved this year for long-time owners. A change effective January 1, 2026 removed a restriction that had excluded older assets from the state’s best tax break. If you founded your company before 2012, that change matters to you directly.
Still, the state rate is only part of the picture. Federal treatment determines most of what you actually keep.
What Changed in 2026
Arizona allows residents to subtract 25% of net long-term capital gains from state gross income. Only 75% of the gain gets taxed. That drops the effective state rate from 2.5% to 1.875%.
Previously, the subtraction covered only assets acquired after December 31, 2011. Anyone holding older property paid the full rate. Founders who built companies in the 1990s watched newer owners get a discount they could not claim.
That restriction is gone. The Arizona State Senate fact sheet for S.B. 1331 sets out the change: beginning with tax years starting January 1, 2026, the subtraction applies to all net long-term capital gains regardless of acquisition date. A $100,000 qualifying gain now costs $1,875 in Arizona tax rather than $2,500.
One limit still applies. Short-term gains, meaning assets held one year or less, do not qualify. Those face the full 2.5%.
How Does Federal Tax Compare
Federal tax takes considerably more than the state does. Long-term capital gains rates run 0%, 15%, or 20% depending on your taxable income. High earners may also owe the 3.8% net investment income tax.
Not every dollar gets capital gains treatment, though. Depreciation recapture on equipment gets taxed at ordinary income rates. Recapture on real estate carries a maximum federal rate of 25%. Both can exceed what you expected when you modeled the sale.
Owners routinely overestimate their net proceeds as a result. The gross price looks impressive. What lands in your personal account looks different.
Does an Asset Sale or Stock Sale Cost You More
Structure drives the outcome, and buyers and sellers usually want opposite things.
Asset Sale
The buyer purchases individual assets instead of the entity. Equipment, inventory, intellectual property, and goodwill all transfer separately. Gains on tangible assets often trigger depreciation recapture at ordinary rates. Goodwill generally receives capital gains treatment. That mix usually raises your total tax bill.
Stock Sale
The buyer acquires ownership shares directly. Your entire gain typically qualifies as a capital gain. Sellers prefer this outcome for obvious reasons. Buyers often resist it, because they inherit every existing liability along with the company.
Consequently, structure becomes a negotiating point rather than a technical detail. Your CPA and transaction attorney can model hybrid arrangements that balance both sides.
Can You Spread the Tax Across Several Years
Yes, through an installment sale. You receive payments over multiple years and report gain only as payments arrive.
That approach offers real advantages. It can keep taxable income inside lower brackets during your early retirement years. It also creates predictable cash flow you can coordinate with other income sources.
However, it introduces buyer default risk. Your retirement income then depends on someone else running your former company well. Careful legal structuring protects the payment obligation, so involve your attorney early. Our income planning guide covers how installment income fits a broader distribution plan.
What About Selling to an ESOP
Section 1042 allows qualifying owners to defer federal capital gains entirely. The company must be a C corporation at the time of sale, the ESOP must hold at least 30% of the stock immediately afterward, and you must have owned the shares for three years. Proceeds then go into qualified replacement property in a window that opens three months before the sale and closes twelve months after.
Meet all of it and the deferral can last indefinitely. Hold the replacement property until death, and the gain may disappear through stepped-up basis. Our guide to Management Buyout vs ESOP works through the eligibility rules and compares that route against selling to your leadership team.
How Arizona Compares to Other States
The flat structure creates predictability that progressive states cannot match. A large sale never pushes you into a higher state bracket, because Arizona has only one.
Compare that with a founder selling in a state that taxes gains at 10% or more. On an identical transaction, their state bill can run several times higher. Arizona also imposes no estate tax and no inheritance tax, which matters once proceeds reach your heirs.
What Should You Coordinate Before Closing
A sale creates one enormous income year. That spike affects far more than your tax return.
- IRMAA surcharges. A large gain raises your Medicare premiums two years later, as our guide to whether Retirement Income Affect Medicare Premiums explains.
- Withdrawal sequencing. Sale proceeds change which accounts you should tap first in retirement.
- Charitable timing. Gifts of appreciated assets can offset gain in the right year.
- Estate documents. Your plan should reflect the new balance sheet, not the old one.
Each piece connects to the others. Handling them separately usually leaves value on the table. Our business exit planning process ties the transaction to the income plan waiting behind it.
