Receiving Social Security Disability Insurance (SSDI) benefits can provide much-needed financial support during difficult times. However, tax complications can arise when those benefits are later determined to have been paid in error and must be repaid.
A recent U.S. Tax Court decision highlights an important tax rule: even if a taxpayer repays Social Security benefits in a later year, the benefits may still be taxable in the year they were originally received. The case of Smith v. Commissioner demonstrates how the annual accounting principle and Internal Revenue Code provisions govern the taxation of Social Security benefits.
The Tax Court ruled that SSDI benefits received by taxpayer Michael Smith in 2022 were taxable, despite the fact that he later repaid the entire amount after the Social Security Administration (SSA) determined he was never entitled to receive the benefits.
The court emphasized that federal tax law taxes income based on the year it is received, not on future events.
Facts
Michael Smith filed his 2022 federal income tax return reporting wages of $16,535 earned from two employers.
Earlier in 2022, Smith had suffered an alleged disabling injury and applied for Social Security Disability Insurance benefits. In November 2022, the SSA approved his application and awarded retroactive disability benefits covering March through November 2022. Monthly payments began in December 2022 and continued through the first three months of 2023.
However, in April 2023, the SSA stopped the payments after discovering that Smith had been working since April 2022. According to the SSA, his employment made him ineligible for disability benefits, meaning he should never have received them.
Smith repaid $31,116 beginning in May 2023 and completed repayment through installments during 2023 and 2024.
Despite receiving $26,802 in SSDI benefits during 2022, Smith did not report the payments on his tax return.
Following an IRS examination, the agency determined that 85% of the benefits ($22,782) should have been included in his taxable income under Internal Revenue Code Section 86.

Issue
The primary issue before the Tax Court was whether SSDI benefits received in 2022 should remain taxable when the taxpayer repaid them in later tax years after the SSA determined the payments were improper.
Smith argued that because he ultimately returned all of the money, the payments should not be treated as taxable income. He compared the benefits to loan proceeds, claiming they were never truly his income.
The IRS disagreed, maintaining that the benefits were taxable when received and that repayments made in later years could not alter the tax treatment of the 2022 tax year.
Law
Internal Revenue Code Section 86 governs the taxation of Social Security benefits.
Under the statute:
- Up to 85% of Social Security benefits may be taxable depending on the taxpayer’s income.
- Social Security benefits include SSDI payments made under Title II of the Social Security Act.
- Benefits are reduced only by repayments made during the same taxable year.
Section 86(d)(2)(A) specifically provides that benefits received are reduced only by repayments made during that taxable year, not repayments made in later years.
Court Analysis
The Tax Court acknowledged that Smith’s situation appeared unfair from a practical standpoint. Nevertheless, the court explained that it is bound by the Internal Revenue Code.
The court relied on the annual accounting principle, which requires taxpayers to calculate taxable income separately for each tax year.
Since Smith received the SSDI benefits in 2022 and did not repay them until 2023 and 2024, those later repayments could not reduce his taxable income for 2022.
The court also cited Section 451(a), which requires cash-basis taxpayers to report income in the year it is actually received.
Claim-of-Right
Smith also relied on the claim-of-right doctrine, established in North American Oil Consolidated v. Burnet, 286 U.S. 417 (1932).
The court explained that this doctrine did not support Smith’s position. The Supreme Court has long held that when a taxpayer receives money under a claim of right and without restrictions, the amount is taxable even if the taxpayer may later be required to repay it.
The Tax Court noted that Smith had applied for the SSDI benefits, received an official approval letter from the SSA, and was paid accordingly. At the time he received the money, there were no restrictions on its use.
Only after the SSA later determined he was ineligible did the repayment obligation arise.
For that reason, the court concluded that the claim-of-right doctrine supported the IRS’s position.

Decision
The Tax Court granted summary judgment in favor of the IRS.
The court held that:
- SSDI benefits received in 2022 were taxable in 2022.
- Repayments made during 2023 and 2024 could not reduce 2022 taxable income.
- Any potential tax relief must be claimed for the years in which the repayments were actually made.
Impact
This decision serves as an important reminder that federal income tax follows the annual accounting system. Income received in one tax year generally remains taxable for that year, even if later events require the taxpayer to return the funds.
Taxpayers who repay Social Security benefits or other income in subsequent years should explore whether relief is available for the repayment year rather than attempting to amend the earlier year’s income solely because the funds were returned.
The Smith case illustrates how the timing of income and repayment can affect federal tax obligations. Because Michael Smith received SSDI benefits in 2022 under a valid SSA determination, those benefits were taxable for that year. His later repayment did not change the tax treatment of the year in which the benefits were received. Instead, any available tax adjustment must be considered in the years the repayments occurred, reinforcing the importance of the annual accounting principle in federal tax law.
