He Hid Cash Income for 30 Years. Now Social Security Is Making Him Pay for It.

For decades, Ray thought he had found a pretty good system. He ran his own plumbing business, took plenty of jobs in cash, reported enough income to keep things moving, and kept more of his money out of the IRS’s hands. Then retirement arrived.

At 66, Ray pulled up his Social Security estimate and discovered the part of the deal he had never really considered. Social Security calculates retirement benefits from the earnings actually reported on your record. The income that never made it onto his tax returns also never helped build his future benefit. After 30 years of underreporting, the smaller tax bills had turned into a smaller Social Security check that could follow him for the rest of his life.

Social Security and inflation figures in this post reflect information available through September 2026. The 2027 Social Security COLA has not yet been finalized and is expected to be announced after the September CPI data are released on October 14, 2026.

The Bill Comes Due Decades Later

Picture a plumber, call him Ray, who spent three decades running a one-truck operation out of his garage. Weekdays were remodels, weekends were emergencies, and a meaningful share of his income arrived in cash. On paper, his business showed a modest living. In reality, he was earning considerably more.

For years, reporting less income meant paying less in taxes. That was not legal, and it came with another consequence Ray may not have thought much about at the time: unreported self-employment income generally does not make it onto his Social Security earnings record either.

Now he is 66, winding down work, and looking at the retirement estimate in his Social Security account. The number is smaller than he expected. The earnings that never made it onto his record cannot simply be treated as though Social Security knew about them all along.

Social Security Only Counts Covered Earnings on Your Record

Social Security does not calculate retirement benefits from what someone remembers earning or what the business actually brought in. It uses the worker’s covered earnings record.

For self-employed workers, the Social Security Administration gets earnings information from federal tax filings. Net earnings from self-employment are reported through the tax system, with Schedule C generally used to calculate business profit and Schedule SE used to calculate self-employment tax. The SSA uses the Schedule SE information when determining Social Security benefits.

If legitimate earnings were never reported, they generally were not credited to the worker’s Social Security record. That can matter decades later when the monthly retirement benefit is calculated.

Your Highest 35 Years Drive the Calculation

For retirement benefits, Social Security generally starts with a worker’s 35 highest years of indexed earnings. Earlier earnings are adjusted to account for changes in national wage levels, and the highest 35 years are added together.

The SSA then divides that total by 420, the number of months in 35 years. The result, rounded down to the next lower dollar, is the worker’s Average Indexed Monthly Earnings, or AIME.

If someone has fewer than 35 years of covered earnings, zero-earnings years can enter the calculation. If someone has 35 years but several years show artificially low earnings, those low years can drag the average down. Either way, the earnings record matters.

For the Self-Employed, Taxes and Benefits Are Directly Connected

Employees normally have Social Security and Medicare taxes withheld from their paychecks. Self-employed workers calculate self-employment tax themselves, generally using Schedule SE.

The current self-employment tax rate is 15.3%, consisting of 12.4% for Social Security and 2.9% for Medicare, although the Social Security portion applies only up to the annual taxable maximum. For 2026, that Social Security earnings cap is $184,500.

The IRS generally calculates the amount subject to self-employment tax using 92.35% of net self-employment earnings. For Social Security purposes, the larger point is simple: reported covered earnings help build the earnings record that eventually determines the retirement benefit.

A $45,000 Reporting Gap Can Follow You Into Retirement

Suppose Ray’s business actually produced about $70,000 a year in net earnings, expressed in roughly today’s dollars, but only about $25,000 a year was reported for Social Security purposes. Sustained over decades, that is a major difference in the earnings history feeding the benefit formula.

For perspective, the Bureau of Labor Statistics reported median weekly earnings of $1,251 for full-time wage and salary workers in the second quarter of 2026. Annualized over 52 weeks, that is about $65,000.

There is no responsible way to assign Ray an exact monthly loss without his actual year-by-year earnings record, wage-indexing factors, date of birth, and claiming age. But decades of reporting tens of thousands of dollars less than the amount actually earned can materially reduce AIME and, in turn, the monthly benefit built from it.

Compare That With Today’s Social Security Checks

The difference becomes easier to appreciate when you look at current benefits. For someone who earned the Social Security taxable maximum every year beginning at age 22 and starts benefits in 2026, the SSA says the maximum retirement benefit is $4,152 per month at full retirement age.

For a maximum earner who waits until age 70 to start benefits in 2026, the figure is $5,181 per month. Those are maximum-benefit examples, not what the typical retiree receives.

As of July 2026, the average retired worker was receiving $2,085.98 per month. A worker whose official earnings record substantially understates decades of actual income can end up well below what the worker expected, even if the business itself produced a comfortable living.

COLAs Do Not Fix a Weak Starting Benefit

Social Security’s annual cost-of-living adjustment helps benefits keep pace with inflation. The adjustment is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W.

The 2026 Social Security COLA is 2.8%. A COLA increases the underlying primary insurance amount before the SSA applies factors such as early or delayed retirement and certain deductions.

The catch for someone like Ray is that the percentage is being applied to a smaller underlying benefit. If two retirees receive the same COLA percentage but one starts with a substantially higher benefit, that person generally receives a larger increase in dollar terms. Over time, the nominal dollar gap can grow even though both benefits are being adjusted under the same COLA formula.

The 2027 COLA Is Not Official Yet

Inflation picked up again during 2026. The Bureau of Labor Statistics reported that CPI-W was 3.5% higher in August 2026 than a year earlier.

That does not mean the 2027 Social Security COLA will automatically be 3.5%. The actual adjustment is based on the average CPI-W during July, August, and September compared with the same three-month period a year earlier.

As of mid-September 2026, The Senior Citizens League projects a 3.5% COLA for 2027, while AARP projects 3.6%. Independent Social Security analyst Mary Johnson has also estimated 3.5%. The final figure is expected after the September CPI report is released on October 14, 2026.

Social Security Has Another Long-Term Problem

Ray’s underreported earnings are one issue. The program’s broader finances are another, and the latest projections have changed.

According to the 2026 Social Security Trustees Report, the Old-Age and Survivors Insurance Trust Fund, which pays retirement and survivor benefits, is projected to deplete its reserves in the fourth quarter of 2032. If Congress made no changes before then, incoming revenue would be sufficient to pay about 78% of scheduled OASI benefits at the point of depletion.

Looking at the retirement and disability trust funds on a combined basis, the trustees project reserve depletion in 2034, with about 83% of scheduled benefits payable at that time. Those are projections under current law, not a prediction that Social Security disappears. Congress can change taxes, benefits, eligibility rules, or other provisions before then.

A Smaller Check Puts More Pressure on Everything Else

The Bureau of Labor Statistics puts average annual spending per consumer unit at about $78,535 in 2024, or roughly $6,545 per month. That is an average across households of many ages and sizes, not a retirement budget, but it gives some perspective on how quickly ordinary expenses add up.

Housing alone averaged $26,266 in 2024, while transportation averaged $13,318. Retirees will have very different spending patterns, but housing, transportation, food, healthcare, insurance, and taxes do not disappear simply because the paycheck does.

If Social Security covers less of Ray’s monthly spending than he expected, the difference has to come from somewhere else: savings, investment withdrawals, a pension, a spouse’s income, continued work, or reduced spending.

Waiting to Claim Can Help, but It Cannot Rewrite the Record

Claiming age still matters. Workers born in 1943 or later earn delayed retirement credits at an annual rate of 8% for months they delay benefits after full retirement age, up to age 70.

That can produce a meaningfully larger monthly check. But delayed retirement credits increase a benefit that was already calculated from the worker’s earnings history. They do not replace decades of missing covered earnings.

Someone deciding whether to claim now or wait should look at the actual dollar amounts shown by the SSA, not simply assume that waiting solves every problem. Health, life expectancy, employment, savings, taxes, and benefits available to a spouse can all affect the decision.

Working Longer Can Replace a Weak Year

There is one part of the benefit calculation that may still be movable. Social Security uses the highest 35 years of indexed earnings, not simply the first 35 years someone worked.

If Ray continues working and properly reports new covered earnings, a stronger new year can replace a lower year already included in his 35-year calculation. The SSA says it reviews the earnings records of people receiving benefits and can recalculate a benefit when new earnings qualify as one of the worker’s highest years.

That will not erase 30 years of underreporting, but it can improve the record at the margins. For someone with fewer than 35 years of earnings, continued covered work can be even more important because it may replace a zero in the calculation.

Old Earnings Records Are Not Always Easy to Correct

Anyone who sees a legitimate mistake in a Social Security earnings record should address it as soon as possible. The SSA says earnings records ordinarily can be corrected only within three years, three months, and 15 days after the end of the relevant tax year.

There are exceptions. The SSA can make certain corrections after that deadline, including confirming earnings supported by tax returns already filed with the IRS and fixing some employer reporting errors.

That is very different from reaching retirement age and simply deciding to add decades of previously unreported self-employment income. Someone facing that situation should talk with a qualified tax professional about the tax issues and with the SSA about what, if anything, can still be corrected on the earnings record.

The Social Security Fairness Act Solved a Different Problem

The Social Security Fairness Act was signed into law on January 5, 2025. It repealed the Windfall Elimination Provision and Government Pension Offset for benefits payable beginning with January 2024.

Those provisions had reduced or eliminated benefits for more than 2.8 million people receiving pensions from work that was not covered by Social Security, including some teachers, firefighters, police officers, federal employees, and workers with foreign pensions.

By July 7, 2025, the SSA said it had completed more than 3.1 million payments totaling $17 billion to eligible beneficiaries, five months ahead of schedule.

That reform does not change Ray’s problem. WEP and GPO involved legally non-covered employment and pension rules. Ray’s issue is an earnings record that does not reflect income that should have been reported in the first place.

Your Spouse Can Feel the Effect Too

A worker’s Social Security earnings history does not necessarily affect only that worker. The primary insurance amount calculated from the worker’s record is also important when the SSA determines certain benefits that may be payable to family members.

Depending on the family’s circumstances, a lower worker benefit can also mean a lower benefit available to a surviving spouse or other eligible survivor. Family maximum rules and the survivor’s own benefit can affect the actual amount, so the impact is not identical in every household.

That makes decades of missing covered earnings more than an individual retirement-planning problem. For married workers in particular, the earnings record can become part of the surviving spouse’s financial picture later.

What Actually Matters From Here

Ray cannot change the choices he made 20 or 30 years ago, but he can stop guessing. The first step is to sign in to a personal Social Security account and review the year-by-year earnings record against tax documents that still exist.

Any genuine reporting errors should be raised with the SSA. If Ray continues working, future earnings should be reported correctly so the SSA can determine whether they replace lower years in his benefit calculation. He should also compare claiming at different ages rather than assuming the first estimate he sees is the only option.

Most important, anyone dealing with years of unreported income should separate two questions: what can legally be corrected on the tax side, and what can still be changed on the Social Security earnings record. Those are not necessarily the same thing, and decades-old self-employment income can involve rules that make professional tax advice worthwhile.

Social Security quietly keeps score for an entire working life. By the time someone reaches retirement, the numbers on that scorecard matter far more than the cash that once seemed convenient to leave off it.
