What to Do After Selling Your Business: A Financial Roadmap

Closing happened. The wire hit. Now what? The first 90 days after a business sale are the highest-stakes financial period most owners ever face — the decisions made (or deferred) immediately after close shape the next decade. Here's a framework for navigating it.

Know your tax bill before you spend a dollar

The most common post-sale financial mistake: treating the wire amount as the number you have to spend. The actual amount you keep is the wire minus federal tax, state tax, and any deal-related expenses. For most owners, that's a 20–35% haircut from the gross proceeds depending on the deal structure and your state.

What you owe — and when

If you took a stock sale or received long-term capital gain, your 2026 federal capital gains rate is up to 23.8% (20% LTCG + 3.8% Net Investment Income Tax for income above $250,000 MFJ / $200,000 single).¹ An asset sale typically produces a blended rate higher than 23.8% because depreciation recapture and covenant-not-to-compete payments are taxed as ordinary income at up to 37%.

If you did an installment sale, you owe tax on each principal payment as received — but depreciation recapture may be taxed in the year of sale regardless, under IRC § 453(i).²

Estimated tax safe harbor

The IRS requires estimated tax payments quarterly. The safe harbor that avoids underpayment penalties: pay at least 110% of your 2025 federal income tax liability (100% if your 2025 AGI was $150,000 or below) spread across four quarterly payments — or in a catch-up payment if the sale closed late in the year.³

The safe harbor avoids penalties — but not the actual tax. If your sale produces $8M of taxable gain, you owe roughly $1.9M in federal capital gains tax regardless. Model this number the week you close. Don't wait for your CPA's April call.

What to do with proceeds immediately after close

Before the investment plan is set, proceeds should sit somewhere safe and liquid: Treasury-only money market funds (not prime funds), T-bills, or bank accounts under FDIC limits. FDIC insures $250,000 per depositor per institution — a $5M wire sitting at a single bank has $4.75M in uninsured exposure. Use multiple institutions or a Treasury-based vehicle.

Don't start investing until you've calculated your tax liability and separated the tax reserve from the investable proceeds. The two numbers are not the same.

Asset allocation reset: from one concentrated bet to a portfolio

For most owners, the business was 70–95% of their net worth. It was illiquid, undiversified, and carried both personal and financial risk. It also had expected returns potentially higher than any public market — which is why the concentration made sense while you were building it.

After a sale, the risk/return calculus reverses. You no longer get compensated for concentration risk. The task is building a permanent, diversified portfolio around a set of goals that didn't exist before: retirement income, estate transfer, charitable impact, and probably some lifestyle spending.

The lump-sum vs. staged deployment question

Finance research is fairly clear that lump-sum deployment into a diversified portfolio outperforms dollar-cost averaging in roughly two-thirds of historical periods, because markets trend up over time.⁵ But behavioral factors matter: a business owner who has never held $8M in public equities may panic-sell during the first significant drawdown if they deployed all at once. The right answer is usually a hybrid — deploy a large portion immediately into your target allocation, and stage the rest over 6–12 months if the behavioral risk is real.

What matters more than the deployment pace: getting the allocation right. A 65-year-old who will need $400K/year from this portfolio needs a different risk/return profile than a 52-year-old who has income from a new venture and won't touch the principal for 15 years. These are not the same portfolio.

Tax-location decisions on a large taxable account

Most of the post-sale proceeds will land in a taxable brokerage account. Tax location — which asset types belong in taxable vs tax-advantaged accounts — matters more at $5M+ than it does at $500K. General rules:

• Taxable accounts: broad-market index funds (low turnover, low dividends), municipal bonds (if in a high tax bracket), tax-managed funds
• IRAs and 401(k)s: REITs, taxable bonds, higher-turnover active strategies
• Municipal bonds: generally appropriate for investors in the 32%+ bracket; the tax-equivalent yield breakeven vs Treasuries depends on your marginal rate

A large taxable account also creates harvesting opportunities during market dips — systematically realizing losses to offset future gains. This is a multi-decade optimization strategy, not a one-time event. The infrastructure matters: which custodian, what reporting, how the portfolio is structured to enable harvesting without sacrificing allocation.

Retirement savings without the business

As a business owner, you likely had access to high-contribution retirement vehicles: a Solo 401(k) allowing up to $24,500 in employee deferrals (2026) plus employer contributions up to 25% of W-2 compensation, a SEP-IRA, or a defined benefit cash balance plan.⁶ These are tied to earned income and business ownership. After the sale, they're gone — at least in the same form.

What's available post-sale

If you take a new job or start a new business, access to employer retirement plans resumes. If you're fully retired, your options for tax-advantaged new contributions narrow significantly:

• IRA contributions require earned income (W-2 wages or self-employment income). If you have no earned income post-sale, you cannot contribute to an IRA for that year.
• Roth conversion ladder: You likely have pre-tax 401(k) or IRA balances from prior years. Post-sale, before you take Social Security or required minimum distributions begin, may be the lowest-income-tax years of your life — making Roth conversions particularly valuable. Converting pre-tax money to Roth fills up lower tax brackets now, reducing future RMDs and estate taxes.
• Rollover/consolidation: Employer plan balances from the old business should be rolled into an IRA or a new employer plan within 60 days of distribution to avoid tax. This is administrative but important — check that your existing Solo 401(k) is properly terminated or transferred.

The Roth conversion window

The year or two after a sale — before new income begins, before Social Security starts — often has unusually low ordinary income relative to your lifetime. A business owner who earned $400K/year and sold for $12M may have a year with $100K in ordinary income plus the capital gain. The capital gain is taxed at LTCG rates; ordinary income fills up lower brackets first. This creates a window to convert pre-tax retirement balances to Roth at lower rates than will ever be available again. The math is worth modeling explicitly.

Estate planning reset

Before the sale, your estate planning was likely designed around a business that was illiquid, hard to value, and the source of your income. That design may be completely wrong for an estate consisting of liquid financial assets.

The $15M exemption — use it strategically

The One Big Beautiful Bill Act (signed July 2025) made the $15M federal estate and gift tax exemption permanent — per person, $30M for a married couple filing jointly, indexed to inflation going forward.⁷ For owners who sold a $10M business, their estate may now approach or exceed this threshold for the first time. The exemption doesn't solve itself — it requires a plan.

Techniques worth reviewing post-sale:

• Annual gift exclusion: $19,000 per recipient (2026), per donor.⁸ A couple with three adult children and six grandchildren can move $342,000 per year estate-tax-free with no paperwork beyond intent.
• Spousal lifetime access trusts (SLATs): Each spouse funds an irrevocable trust for the other. Both get access (via the beneficiary spouse), and the assets are outside both estates at death.
• Irrevocable life insurance trusts (ILITs): Life insurance owned outside your estate — proceeds pass income- and estate-tax-free to heirs.
• Grantor retained annuity trusts (GRATs): Transfer growth above the IRS § 7520 hurdle rate to heirs estate-tax-free. Particularly effective in high-growth environments; less so when rates are elevated.

Update beneficiary designations on every account. IRAs, 401(k)s, life insurance, and annuities pass by beneficiary designation — outside the will entirely. It is common to find a post-sale estate with $8M in a brokerage account that, per the documents, goes to the owner's first spouse from 20 years ago.

Charitable giving after a liquidity event

A large liquidity event creates an unusually large income in one year — which means the charitable deduction is unusually valuable in that same year. The mechanics of timing matter.

Donor Advised Fund (DAF)

A DAF is the most flexible post-sale charitable tool. You contribute cash or appreciated securities to the fund in the year of the sale (taking the deduction in the high-income year), then recommend grants to charities over multiple years at your own pace. The assets grow tax-free inside the fund. You can contribute up to 60% of AGI in cash to a DAF and carry forward excess deductions for five years.

Funding a DAF in the year of the sale accelerates the deduction to offset the sale income, even if you haven't decided which charities to support.

Qualified Charitable Distributions (QCDs)

If you are 70½ or older, you can direct up to $111,000 (2026) directly from your IRA to a qualified charity — tax-free, not reported as income.⁹ QCDs also satisfy required minimum distributions starting at age 73 (or 75 for those born in 1960 or later, per SECURE 2.0).¹⁰ The QCD limit is per person — a married couple can exclude $222,000 in IRA-to-charity transfers annually.

Charitable Remainder Trusts (CRTs)

A CRT is most powerful when funded with appreciated assets before the sale closes — the trust sells the business interest, avoids immediate capital gain, and pays the owner an annuity stream over time. Post-sale, funding a CRT with cash is still viable for ongoing income and the deduction, but the capital gain advantage is lost. If CRT pre-sale planning wasn't done before your closing, it's worth modeling whether a post-sale CRT still makes sense for your specific income and charitable goals.

Finding a post-sale financial advisor

Your M&A attorney optimized the legal structure. Your investment banker maximized the headline price. Your CPA filed the return. None of them are equipped to coordinate what happens next: constructing a lasting financial plan from a large, sudden pool of liquid assets.

A post-sale financial advisor — specifically a fee-only fiduciary with experience handling liquidity events — does four things the others don't:

1. Integrates tax, investment, and estate in one model. The Roth conversion strategy, the portfolio construction, and the estate plan interact. Optimizing each separately produces a worse outcome than coordinating all three.
2. Builds a sustainable withdrawal plan. What does $7M in liquid assets need to produce per year, for how long, with what probability? This math requires assumptions about spending, longevity, market returns, and inflation that a CPA or attorney doesn't model.
3. Has no product to sell. Fee-only advisors are paid by you — not by commissions on the annuities, insurance, or funds they recommend. This matters most when someone hands you a large check: the commission-incentivized product push tends to arrive within 72 hours of the wire.
4. Has seen this before. Post-sale psychology is real. The identity shift from business owner to investor, the sudden disappearance of daily structure, the temptation to deploy capital too quickly into new ventures — an experienced advisor who has worked with former business owners knows what to watch for.
