Oklahoma guide
After the sale:
the first year of being the money’s manager.
The wire lands, and a person who ran a company for twenty years starts a job they have never held: steward of a liquid fortune. The first year has real deadlines, quarterly taxes, the Oklahoma deduction’s paperwork, a charitable window, and real dangers, most of them sold enthusiastically by phone. This page is the first-year map. The pre-sale calendar is its own guide, linked below, and so is the deduction itself.
What should I do first after selling my business?
Three things in the first quarter: park the proceeds somewhere boring and liquid, Treasury bills and insured deposits, while decisions get made deliberately; schedule the taxes, because the IRS expects an estimated payment on the sale gain by the next quarterly deadline and Oklahoma’s own schedule runs alongside; and file the paper trail for the Oklahoma capital gains deduction, which at 4.5% of the gain is worth more than any investment decision you will make this year. The portfolio, the giving, and the estate design come after those three, in that order, and none of them rewards speed.

The rule
Five facts for the first year.
Nothing here requires speed, and two things punish it: taxes misscheduled and money invested before the plan exists. The deadlines below are the real ones.
The IRS does not wait for April; the quarter you close in sets the deadline.
Tax on the gain is due through estimated payments in the quarter the gain lands, at the January, April, June and September deadlines, with the federal safe harbor at 110% of last year’s tax for high earners and Oklahoma’s at the smaller of 70% of this year or 100% of last, with 20% annual interest on shortfalls. The cleanest first-year move is funding a separate account with the full tax reserve, federal at up to 23.8% on the gain including the net investment income tax, Oklahoma at whatever the deduction does not cover, the week the wire arrives.
The Oklahoma deduction is claimed on paper you must be able to produce.
Form 561 wants the dates that prove the two-year ownership and the company’s Oklahoma headquarters history, and an installment sale claims its deduction year by year on the same proof. Close the data room into a permanent file: cap table history, formation documents, the purchase agreement, the allocation. At 4.5% of the gain, this folder is likely the highest-value hour of filing you will ever do, and it is far easier assembled in the month after close than three Aprils later under audit.
The 2026 charitable rules reward one big, planned year of giving.
From 2026, itemized charitable deductions only count above a floor of 0.5% of adjusted gross income, and top-bracket taxpayers get at most 35 cents per dollar given. In a sale year the floor is at its largest, but so is the stack of appreciated assets and the bracket itself, and a donor-advised fund still lets one deliberate contribution fund a decade of giving while the deduction lands against sale-year income. Gifts of appreciated stock held over a year still avoid the capital gain entirely. The arithmetic deserves an afternoon, before December, not after.
Sold QSBS early? Sixty days to roll it.
If the stock sold was qualified small business stock held more than six months but short of the exclusion holding period, § 1045 allows the gain to be rolled into new qualified small business stock within 60 days, preserving the clock. It is the one genuinely fast deadline in this list, it is easy to miss while celebrating, and it only matters to sellers who want to fund another operating company rather than a portfolio.
The exemption window and the protection window are both open now.
The federal estate and gift exemption is $15 million per person from 2026, indexed, and Oklahoma has no estate or gift tax, so a couple can move $30 million of what is now easily valued, liquid wealth into trusts for children with no transfer tax, while Oklahoma’s Family Wealth Preservation Trust can shelter assets with an in-state trustee. Protection planning works only ahead of trouble: transfers made with existing claims in view can be unwound for years under the fraudulent transfer act. The month after close, with no lawsuits and no new ventures yet, is the cleanest window a family ever gets.
The trap
How sale proceeds get hurt, in order of frequency.
None of these is a market crash. They are decisions, every one avoidable by going slower than the person proposing them.
Concentrating again, because concentration is what got you here.
An owner’s instinct is to put a third of the proceeds into one gripping idea, a friend’s company, a building, the industry just exited. The business deserved concentration because you controlled it; a passive stake controls nothing and diversifies nothing. The useful discipline is a written cap for private deals, decided calmly in the first quarter, before the first pitch arrives, because the pitches have already started.
The months after a publicized sale are high season for being sold to.
Indexed annuities with decade-long surrender schedules, life-insurance structures pitched as tax plans, private placements with glossy decks: each arrives with urgency attached. A one-sentence policy filters all of it: nothing is bought in the first six months, and nothing is ever bought from the person who proposed it without an independent fiduciary second opinion. Anyone offended by that sentence has explained their compensation.
Waiting in cash forever is the quiet opposite mistake.
A deliberate quarter in Treasury bills is wisdom; a third year of waiting for the perfect entry is a plan failing silently, in inflation and missed compounding. The exit from cash is a schedule, not a feeling: a written target portfolio and dated steps into it, mechanical enough to continue through whatever the market is doing on each date.
The decision
The first year, on a calendar.
The first month: proceeds into Treasury bills and insured deposits across institutions; the tax reserve funded and walled off; the Form 561 file assembled; umbrella liability coverage sized to the new balance sheet; and a pause on every investment decision that is not a deadline. Nothing in this paragraph requires talent, only the willingness to be briefly boring.
The first quarter: the estimated payments made; the written investment policy, what the money must do, in what order, with how much set aside for private risk; the charitable plan for the sale year, donor-advised fund included, decided while the deduction is worth the most; and the § 1045 question answered if it applies. This is also when the paycheck gets designed, the monthly transfer from portfolio to checking that replaces the salary, sized by the arithmetic in the calculator below.
The first year: the portfolio built out on its schedule; the estate design executed against the $15 million window with your attorney, trusts funded while values are clean and liquid; the protection layer, entity housekeeping and any Family Wealth Preservation Trust, put in place ahead of whatever you do next; and one honest review of what the year taught. We sit on the owner’s side of this entire calendar, a fiduciary unaffiliated with anything being sold, which in this particular year is the point.

Questions we get
Asked often enough to answer here.
How much tax will I pay on my business sale?
Federally, long-term gain is taxed at 15% or 20% plus the 3.8% net investment income tax above $250,000 of income for joint filers, with any depreciation recapture at ordinary rates. Oklahoma taxes gain at up to 4.5% in 2026, unless the gain qualifies for the state’s 100% capital gains deduction, which our guide to the deduction covers in detail. The blend is specific to your structure and allocation, which is why the modeling belongs before the sale.
Where should I park the money right after closing?
Liquid and dull: Treasury bills, money market funds holding government paper, and deposits spread within insurance limits. The yield is real while the plan is written. The parking is the easy part; the discipline is leaving it parked while the investment policy, tax reserve and estate design get done in the right order.
Is the 4% rule real?
It is a research finding, not a law: starting withdrawals near 4% of a diversified portfolio, adjusted for inflation, survived every 30-year period in the historical studies that made it famous. It is a useful reference point for sizing spending, and an actual withdrawal plan should be tax-aware, flexible year to year, and revisited as markets and life change.
Should I set up a donor-advised fund in my sale year?
If charitable giving is part of your life, the sale year is usually the single best year to fund one: the deduction lands against your highest-ever bracket, appreciated stock can go in without realizing gain, and from 2026 the 0.5% floor makes scattered small-year giving less efficient than one planned contribution. The grant-making then proceeds at whatever pace you like for years.
