He Sold His Plumbing Company but Stayed On to Help. The Consulting Paycheck, Not the Sale, Is What Shrinks His Social Security.
He built a plumbing company for thirty years, sold it, and agreed to stick around for the handoff. That decision to stay triggered a Social Security problem he never saw coming.
A 64-year-old plumber spends three decades building a company, then sells it to a national buyer. As part of the deal, he agrees to stay for about 18 months, introducing customers to the new owners and training the incoming manager. He started Social Security a couple of years earlier. Then part of his monthly benefit disappears. He assumes the sale price caused it. The more likely culprit is the paycheck attached to the handoff.
Home-services deals like his are increasingly common. Reuters recently reported that Apollo invested $2 billion in Apex Service Partners, valuing the nationwide HVAC, plumbing, and electrical platform at approximately $10 billion, including debt. Apex employs more than 7,800 tradespeople. When private capital rolls up the trades, founders often remain long enough to transfer customer relationships and train the next operator. That transition income is where Social Security suddenly re-enters the picture.
Why Most of the Sale Price Does Not Trigger the Earnings Test
Social Security’s retirement earnings test applies before full retirement age (FRA). For anyone born in 1960 or later, that age is 67. Before then, SSA may withhold benefits when wages or net self-employment income exceed an annual limit. Capital gains from selling stock, goodwill, or qualifying business property generally do not count as earnings. Neither do dividends, interest, or the investment portion of installment payments. A seven-figure closing check can therefore remain invisible to the earnings test.
The purchase agreement still matters. A business sale can divide consideration among equipment, inventory, goodwill, seller financing, a noncompete agreement, and compensation for future services. Not every dollar receives identical tax or Social Security treatment.
The clearest earned-income piece is what the buyer pays him to stay. If he becomes a W-2 employee, the wages count. If he operates as an independent consultant, his net self-employment earnings count. Calling compensation an earn-out or transition payment will not remove it from the test if the money is actually tied to work he performs.
How the Withholding Feels
In 2026, someone under FRA for the entire year can earn $24,480 before withholding begins. SSA then holds back $1 in benefits for every $2 earned above the limit.
Suppose the plumber receives $60,000 for a full year of transition work. That is $35,520 above the limit, potentially causing $17,760 in benefits to be withheld. On a $2,400 monthly Social Security benefit, that represents more than seven months of checks. During the calendar year he reaches full retirement age, the limit rises to $65,160, and SSA withholds $1 for every $3 earned above it. Only income earned before the month he reaches FRA counts. Starting with that month, the test disappears.
Benefits withheld under the test are not forfeited permanently. At full retirement age, SSA adjusts the monthly amount to account for months in which benefits were withheld. The money does not return in a lump sum, and recovering it through a larger monthly check takes time. Cash flow today remains the immediate problem.
The Planning Lever Is the Work, Not Its Label
The cleanest options involve the actual timing and scope of the transition. He might finish the work sooner, reduce the duties and compensation, or schedule more of the handoff after the month he reaches FRA. Hours alone do not control the annual earnings test. The dollar amount of wages or net self-employment income does. Any payment schedule must reflect a genuine business arrangement and the services actually performed. Moving words around inside the agreement without changing the work will not necessarily change SSA’s answer.
The sale can still reach Social Security through taxation. A large capital gain may push up to 85% of his benefit into taxable income. It can also raise Medicare Part B and Part D premiums roughly two years later through the Income-Related Monthly Adjustment Amount (IRMAA). Those are real costs, but they are separate from benefit withholding. The earnings test looks at work. Social Security taxation and Medicare look at wider measures of income.
What to Settle Before Closing
Two questions belong in the deal discussion:
- How much consideration is genuine purchase price, and how much compensates him for post-sale services?
- Can the transition begin later or place more compensated work after his full-retirement-age month?
The biggest number in the agreement may never touch the earnings test. The smaller paycheck for staying behind often does. Before closing, the purchase-price allocation and transition agreement deserve review from someone who understands both business-sale taxation and Social Security.
