The tax moves to make 2–3 years before you sell your business
The tax on a business sale is largely decided before the letter of intent arrives. Here’s what to do in the two to three years before you sell — and why the order matters.
Key takeaways
- Most of the tax on a business sale is locked in before the letter of intent.
- QSBS, gifting and entity changes need years of lead time.
- Gifts and charitable transfers of shares generally need to happen before a deal is effectively agreed.
- Deal structure, installment timing and residency shape the final bill.
The short answer
Most of the tax on a business sale is locked in before a term sheet arrives. Two to three years out, the moves worth making are: review your entity and QSBS eligibility, gift shares to trusts while values are still pre-deal, consider a defined benefit plan, plan charitable and installment structures, and settle residency — each coordinated with your CPA and attorney.
When to act
3+ years out
Review entity type and QSBS eligibility. Under current law, stock acquired after July 4, 2025 needs three to five years to reach the partial and full federal exclusion.
2–3 years out
Gift shares to trusts at pre-deal values, adopt a defined benefit or cash balance plan, and settle any residency plans.
Before the letter of intent
Model deal structure — asset or stock sale, price allocation, installment or earnout — and complete any charitable transfer of shares.
The year of the sale
Time the income, fund the retirement plan, cover estimated taxes and put a plan in place for the proceeds.
Why the closing table is too late
Selling a business is usually a once-in-a-lifetime tax event. It touches your income tax, capital gains, retirement plan, estate and investments in the same year. Most of the tools that shape that bill have lead times. Some need years to season. Others stop working once a deal becomes likely.
By the time a buyer sends a letter of intent, the price is largely set, the structure is being negotiated, and gifts or charitable transfers of shares are harder to do cleanly. That’s why the planning window opens two to three years before a sale, not at closing.
Entity and QSBS: the longest clock
If your company is — or could become — a C corporation, Section 1202 Qualified Small Business Stock (QSBS) may exclude a large share of the gain from federal tax. Under current law, as amended by the One Big Beautiful Bill Act, stock acquired after July 4, 2025 can qualify for a 50% exclusion after three years, 75% after four and 100% after five. The excluded gain is generally capped at $15 million per company (or ten times your basis, if greater), and the company’s gross assets must be no more than $75 million when the stock is issued.
The clock only starts when qualifying stock is issued. Converting a pass-through entity to a C corporation can start one in some cases, but generally only growth after the conversion can qualify — and a C corporation has trade-offs of its own, including a second layer of tax if a buyer insists on an asset sale. Many professional-service businesses, such as law, accounting, health and consulting firms, don’t qualify at all. And California does not conform, so the state still taxes the gain. This is a decision to model with your CPA and attorney years before you need it.
Estate and gifting: move value before it has a price
Under current law, the federal estate and gift tax exemption is $15 million per person in 2026, indexed for inflation. For owners whose estate may exceed it, the years before a sale are often the best time to give. Shares transferred to a trust for family while an appraisal reflects the company as it stands — not a negotiated deal price — move future growth out of the estate.
Gifts to certain non-grantor trusts can also, in some cases, “stack” additional QSBS exclusions. Timing cuts both ways. Once a sale is effectively agreed, a gift of shares can be treated as a gift of the sale proceeds: the gain may still be taxed to you, and the value reflects the deal. Your attorney leads the drafting; we model the numbers and the calendar.
An illustrative example
Consider a hypothetical owner of a profitable California manufacturing company who expects serious buyer interest in about three years. Three years out, she asks her CPA and attorney to review the entity and whether QSBS planning is realistic, and she gets a baseline valuation. Two to three years out, her attorney drafts a trust for her children and she gifts a minority interest, appraised before any buyer has named a price. She also adopts a cash balance plan to add deductions in her highest-earning years. A year before going to market, she models asset vs. stock terms, price allocation and an installment option, so she negotiates knowing the after-tax result of each. None of this is exotic. What changes the outcome is that each move happened while it still could. Hypothetical and simplified — not a recommendation or a guarantee of any result. The right moves depend on your facts and on current law.

Retirement plans and charitable structures: build them early
A defined benefit or cash balance plan, layered on a 401(k), can create large deductible contributions in the high-earning years before a sale. It has to be designed and adopted in time, funded on schedule and planned around the transaction — which is why it belongs in the plan two to three years out, not in the sale year.
For owners with charitable goals, a charitable remainder trust or donor-advised fund funded with shares can reduce or spread the tax on the gain. Like gifts to family, the transfer generally needs to happen before a sale is binding or effectively certain. Waiting for the wire usually means the gain is already yours.
Deal structure, installments and where you live
Structure can change what you pay as much as any strategy. Buyers often prefer an asset sale; sellers often prefer a stock sale. How the price is allocated — goodwill, equipment, a non-compete, a consulting agreement — decides how much is taxed as capital gain and how much as ordinary income. These are negotiating points, best modeled before you’re at the table.
An installment sale or earnout can spread gain across several tax years, which can help with brackets and cash flow — at the cost of waiting to be paid and carrying the buyer’s risk. Some income, such as depreciation recapture, is generally taxed in the year of sale regardless.
Residency matters too. California taxes residents on their gain and does not follow the federal QSBS exclusion. A move made shortly before a sale draws scrutiny and may not change the result. If relocating is genuinely part of your plans, it needs to be real, documented and early.
Start with a map, not a transaction
The first step isn’t a transaction. It’s a map: what the business is worth today, how a sale is likely to be structured, when it might happen, and which of these moves still fit the calendar. Then each move gets a date. We build that plan alongside your CPA and attorney, who implement their parts of it.
- Confirm your entity type, your QSBS status and when any clock started.
- Get a current valuation baseline before a buyer sets one.
- Decide on gifting, trusts and charitable goals while shares can still move cleanly.
- Model asset vs. stock, price allocation and installment options.
- Settle residency plans — and the plan for the proceeds.
Common questions
Is it too late to plan if I already have a buyer?
Not entirely. Deal structure, price allocation, installment terms and sale-year moves can still matter. But gifts and charitable transfers of shares get harder once a sale is effectively agreed, and a QSBS holding period can’t be shortened. The earlier the conversation, the more options remain.
Does QSBS apply to my business?
Only if the company is a C corporation that met the rules when your shares were issued — including, for stock issued after July 4, 2025, a $75 million gross-assets test — and runs a qualifying active business. Many professional-service firms are excluded. Your attorney and CPA confirm eligibility; we plan around the clock.
Who else should be involved?
Your CPA and your transaction or estate attorney, and often an appraiser and, for a defined benefit plan, an actuary. We don’t replace them. We coordinate the timing so each move happens in the right order, with the tax modeled before anyone signs.
