What to Do After Selling Your Business

The Direct Answer: What to Do After the Sale Closes

Pause. Park. Plan. Then invest. The most common mistake business sellers make is treating their sale proceeds like a salary — immediately putting it to work in the market, spending it on upgrades, or wiring it to the first investment advisor who calls. Don't.

The 90-day rule is simple: do nothing with the money for the first 30 days, park 100% in a high-yield savings account or 6-month T-bills for the next 60 days, and use that time to build a proper plan with your CPA and financial advisor. T-bills are currently yielding 4.5-5% — you're earning money while you think.

Why this matters: the moment your wire hits your account, you have a tax liability that typically represents 30-35% of the sale price. Federal long-term capital gains (15-20% federal + 3.8% NIIT), state income taxes (4-9%), broker fees (8-12%), and legal/accounting ($15K-$50K). On a $2M sale, that's $640K-$700K gone before you've spent a dollar. The sellers who make headlines — the ones who liquidate their $2M business and feel rich — often have a $400K tax bill they didn't see coming.

This playbook covers exactly what to do in each of the three phases: the first 30 days, days 31-90, and months 3-12.

Days 1-30: The Pause Rule

The first month after close is for calculation, not action. Here's the checklist:

• Wire to a high-yield savings account — Ally, Marcus, or Discover are currently paying 4.3-4.6% APY. Not exciting, but safe and earning while you plan. Better yet: buy 6-month T-bills directly at TreasuryDirect.gov (currently ~4.8-5%).
• CPA meeting — within 2 weeks of close — Bring your sale documents, cost basis, and prior 3 years of business tax returns. Ask them to model your estimated federal + state tax liability. Ask them to set up quarterly estimated tax payments for the following year. You may owe 110% of prior year liability to avoid underpayment penalties.
• Open a separate tax reserve account — Transfer the estimated tax amount to a dedicated savings account. On a $2M sale with $1.5M gain, that's typically $400K-$550K depending on your state and bracket. This money is not for spending — it's for the IRS on April 15.
• Do not sign any investment advisory agreements — You will receive calls, emails, and LinkedIn messages from financial advisors the moment the deal closes. They know you're newly liquid. Get your plan built before you sign anything. Fee-only CFPs (NAPFA.org) or ChFEBCs (for federal employees) charge flat fees or hourly — avoid percentage-of-AUM advisors who take 1% of $2M ($20,000/year) for work you can do yourself with the right tools.
• Update beneficiary designations on all existing accounts — 401(k), IRA, insurance policies. Your sale proceeds are now a major portion of your estate. Make sure the beneficiaries are correct and current.

Days 31-90: Your Net Number & Income Gap

Once your CPA has modeled the tax situation, you have your real number. Now apply the 4% rule to understand your retirement picture:

Required Nest Egg = (Annual Retirement Expenses − Guaranteed Income) × 25

Guaranteed income includes Social Security, pension, rental income, and any other reliable sources that aren't dependent on markets or your ability to work. If your annual expenses are $80,000 and you receive $30,000/year from Social Security, your income gap is $50,000/year — requiring a $1,250,000 nest egg at a 4% withdrawal rate.

Sale Price	Net After Tax (~68%)	4% Annual Income	Monthly Income
$500,000	$340,000	$13,600/yr	$1,133/mo
$1,000,000	$680,000	$27,200/yr	$2,267/mo
$1,500,000	$1,020,000	$40,800/yr	$3,400/mo
$2,000,000	$1,360,000	$54,400/yr	$4,533/mo
$3,000,000	$2,040,000	$81,600/yr	$6,800/mo

These figures are the base from your business sale alone. Most retirees also have Social Security, a pension, or other income streams — which combine with these numbers to build a complete retirement income picture.

Choosing Your Investment Philosophy

This is the most important decision you'll make post-sale. Don't try to do all three — pick one and commit:

Path A: Income Floor Strategy

Allocate 50-60% of net proceeds to a Single Premium Immediate Annuity (SPIA) at age 65+. This generates guaranteed lifetime income regardless of market conditions or how long you live. The remaining 40-50% goes to a diversified 60/40 portfolio of index funds and bonds.

Why this works for business sellers: You've spent 20-30 years building an asset. The last thing you want is sequence-of-returns risk in the first 5 years of retirement. A SPIA income floor means you always know your minimum income — market volatility doesn't threaten your food budget.

Path B: Total Return Strategy

Allocate 100% to a diversified portfolio of low-cost index funds (60% equities, 40% bonds). Live off the portfolio's distributions and systematic withdrawals. Rebalance annually.

Best for: Sellers who want maximum flexibility, have other guaranteed income (pension, high Social Security), and are comfortable with market variability. Requires discipline not to sell equities during downturns.

Path C: Bucket Strategy

Segment your portfolio into three time-horizon buckets:

• Bucket 1 (Years 1-2): 100% cash/HYSA/T-bills — $80,000-$150,000 depending on expenses. No market risk.
• Bucket 2 (Years 3-7): Bonds, CDs, bond funds — 25-30% of growth portfolio. Income generation without equity volatility.
• Bucket 3 (Years 8+): Diversified equities (index funds, ETFs) — 70-75% of growth portfolio. Long-term compounding.

Withdrawals sequence from Bucket 1 → 2 → 3 over time. Bucket 3 gets to compound uninterrupted for as long as possible.

Critical Decisions in the First 90 Days

Social Security Timing

Post-sale is one of the best times to optimize your Social Security claiming strategy. You have capital, flexibility, and no employment income. Here's the framework:

Claiming Age	Monthly Benefit vs. FRA	Best For
Age 62 (early)	70% of FRA benefit	Those who need income immediately; health concerns
Age 66-67 (FRA)	100% of FRA benefit	Average longevity outlook; need income now
Age 70 (delayed)	124-132% of FRA benefit	Strong other income; good health; longevity in family

Delaying to 70 maximizes lifetime benefits if you expect to live past 78-80 (the breakeven point). On a $2,500/month FRA benefit, delaying to 70 gives you $3,100-$3,300/month — that's $7,200-$9,600 more per year, every year, for the rest of your life. Use the Social Security Optimizer to model your specific claiming scenarios.

Healthcare Bridge (If Pre-Medicare)

If you sold before age 65, healthcare is your largest new expense. Here's the decision framework for the first 90 days:

• COBRA: Up to 18 months of your former employer plan. Expensive ($600-$2,500/month for individual) but seamless if you have ongoing medical needs. You have 60 days to elect after the sale closes.
• ACA Marketplace: Often the most cost-effective for business sellers. Subsidies are based on projected income — if you have no W-2 income, your subsidies can be substantial. Report capital gains carefully; a large gain in one year can affect eligibility.
• Spouse's employer plan: If married and your spouse has employer coverage, this is often the most cost-effective option.

The 90-day window is when you make this decision. COBRA has a hard 60-day election window. If you're under 65 and sold, make this call in the first week.

Estate Planning Update

Your sale proceeds are a significant change to your estate. Update the following in the first 90 days:

• Will and Living Trust: Review with an estate attorney. Sale proceeds may push you over federal or state estate tax exemptions — currently $13.61M federal per person (2026). If your estate exceeds that threshold, trust structures can reduce estate tax exposure.
• Beneficiary designations: Update on all accounts (401k, IRA, brokerage, insurance). These override your will — make sure they're current.
• Healthcare directive and power of attorney: Ensure these are signed and accessible. These documents are critical if you become incapacitated — without them, your family faces expensive court proceedings.
• Durable power of attorney: Allows someone to manage your financial affairs if you're incapacitated — essential for someone with $2M+ in liquid assets.

Months 3-12: Gradual Deployment

Don't invest 100% of your remaining capital on day 91. Research shows that investing a lump sum immediately outperforms dollar-cost averaging about 66% of the time — but that research is based on institutional investors with no behavioral risk. For business sellers who've never managed this much liquid capital before, behavioral risk is real.

The recommended approach: deploy over 6-12 months in three tranches.

• Month 3: Invest the first 33% of your deployment capital (not including tax reserve or SPIA allocation). This captures some of the potential upside immediately.
• Month 6: Invest the second 33%. If markets dropped 10-15% in the first 3 months, this is actually good — you're buying more with the second tranche.
• Month 9-12: Deploy the final 33%. By month 12, you should be fully invested in your chosen allocation.

This approach gives you partial lump-sum performance upside while reducing the stress of "investing everything at the top." It's not optimal from a theoretical returns standpoint, but it's optimal from a behavioral and stress standpoint — which matters for long-term investment success.

Identity and Purpose After the Sale

One topic that doesn't appear in financial plans but dominates post-exit satisfaction: identity. For 20-30 years, you were a business owner. That was your title, your daily structure, your social network, and your sense of purpose. When it disappears overnight, the void is real.

The research on post-exit satisfaction is clear: former owners who have a written plan for the first 12 months post-sale — advisory board roles, board service, part-time consulting, a new venture, or defined retirement activities — report significantly higher satisfaction than those who simply "retire and travel."

This isn't soft advice. It's financially relevant: purpose and social connection are linked to better health outcomes, lower healthcare costs, and longer, more active lives. A former owner who stays engaged earns advisory income, maintains professional networks, and has a reason to stay sharp.

Use the first 90 days to build your Year 1 plan. Not a financial plan — a life plan. What will you do Monday morning? Who will you do it with? What does success look like at the one-year mark? The sellers who plan for this have better outcomes than those who don't.
