The Trial Work Period does not change how SSDI taxes work

During your Trial Work Period (TWP), you keep your full SSDI payment every month, no matter how much you earn. The TWP is a nine-month window (not necessarily consecutive) where work does not reduce your benefit. But the IRS still counts that income on your tax return, and you may owe federal income tax, self-employment tax, or both.

The confusion happens because SSDI itself is not taxed — Social Security never withholds from your check. What gets taxed is your wages or self-employment income during the TWP. The amount of your SSDI payment does not change, but your total income for the year does, and that affects your tax bill.

Key Takeaways

  • SSDI payments themselves are never taxed, but wages you earn during your Trial Work Period are subject to federal income tax and self-employment tax.
  • You must report all earnings to Social Security within the month you earn them, even though those earnings do not reduce your benefit during the TWP.
  • Up to 85 percent of your SSDI can become taxable if your "combined income" (SSDI plus half your net earnings plus other income) exceeds a threshold that has not changed since 1984.
  • Self-employment income during the TWP is subject to the full 15.3 percent self-employment tax, the same as any other year.
  • You should report TWP earnings to Social Security and to the IRS; failing to report to Social Security can end your TWP early or trigger overpayment recovery.

When SSDI becomes taxable income

SSDI becomes taxable only if your combined income exceeds a set threshold. Combined income is calculated as: your SSDI payment plus half your net earnings (wages or self-employment income) plus any other income like interest, dividends, or pensions.

For 2024, the thresholds are $25,000 for a single filer and $32,000 for married filing jointly. These thresholds have not changed since 1984. If your combined income is below the threshold, none of your SSDI is taxable. If it exceeds the threshold, up to 85 percent of your SSDI becomes taxable income on your federal return.

Example: You receive $1,200 per month in SSDI ($14,400 per year) and earn $15,000 in wages during your TWP. Your combined income is $14,400 + ($15,000 ÷ 2) + $0 = $21,900. Since $21,900 is below $25,000, none of your SSDI is taxable. You owe income tax only on the $15,000 in wages.

If you earn $25,000 in wages instead, combined income becomes $14,400 + ($25,000 ÷ 2) + $0 = $26,900. The excess over $25,000 is $1,900. You would owe tax on the lesser of (a) 50 percent of the excess ($950) or (b) 85 percent of your SSDI ($12,240). In this case, $950 of your SSDI becomes taxable.

Self-employment tax during the Trial Work Period

If you are self-employed during your TWP, you owe self-employment tax on your net earnings at the standard rate of 15.3 percent (12.4 percent for Social Security, 2.9 percent for Medicare). The TWP does not exempt you from this tax. Social Security does not withhold self-employment tax from your SSDI payment, so you must plan to pay it when you file your return or make quarterly estimated tax payments.

Self-employment income is also counted toward your combined income for purposes of determining whether your SSDI is taxable. If your net self-employment income is high enough to push your combined income above the threshold, part of your SSDI becomes taxable on top of the self-employment tax you already owe.

You report self-employment income on Schedule C (or Schedule C-EZ) and self-employment tax on Schedule SE. If you have questions about what counts as net earnings, the IRS Publication 334 (Tax Guide for Small Business) covers the basics, though a tax professional familiar with SSDI can help you avoid mistakes that might trigger an audit or overpayment notice from Social Security.

Reporting earnings to Social Security during the TWP

You must report all earnings to Social Security within the month you earn them, even though those earnings do not reduce your SSDI payment during the TWP. Failure to report can result in an overpayment notice later, or Social Security may end your TWP early and move you into the Extended may be able to access Period, where earnings do reduce your benefit.

Report earnings by calling your local Social Security office or by using your my Social Security account online. You will need to provide the month, the amount earned, and whether the income was from wages or self-employment. Keep pay stubs, invoices, or other records so you can verify the amounts if Social Security asks.

The reporting requirement is separate from your tax filing. Even if you do not owe federal income tax (because your income is below the filing threshold), you still must report the earnings to Social Security. Conversely, if you file a tax return, make sure the income you report to Social Security matches what you report to the IRS.

How to plan for taxes during the Trial Work Period

Start by estimating your total income for the year: SSDI plus expected wages or self-employment income. Use the IRS tax tables or a tax calculator to estimate your federal income tax liability. Then add self-employment tax if you are self-employed. This total is what you will owe when you file.

If you are an employee, ask your employer to withhold federal income tax from your paycheck. This reduces the amount you owe at tax time. If you are self-employed or expect to owe more than $1,000, consider making quarterly estimated tax payments to the IRS (Form 1040-ES) to avoid a penalty for underpayment.

Keep a separate folder for TWP-related documents: pay stubs, 1099 forms, invoices, receipts, and any correspondence from Social Security about your earnings. When tax time arrives, you will have everything in one place. If you are unsure whether you owe tax or how much, a tax professional or a free tax clinic (many are run by VITA — Volunteer Income Tax information — and serve low-income filers) can review your situation.

What happens to taxes after the Trial Work Period ends

Once your nine-month TWP ends, you enter the Extended may be able to access Period (EEP), which lasts 36 months. During the EEP, your SSDI payment is reduced by $1 for every $2 you earn above the monthly earnings limit (called the Substantial Gainful Activity, or SGA, amount). For 2024, SGA is $1,550 per month for non-blind beneficiaries and $2,590 for blind beneficiaries.

Your tax situation does not change: you still owe federal income tax and self-employment tax on your earnings. But now your SSDI payment itself may be reduced, which lowers your combined income and may reduce the portion of your SSDI that is taxable. You still must report earnings to Social Security each month.

After the EEP, if you continue to work and earn above SGA, you enter Expedited Reinstatement, a five-year period during which your benefits can be reinstated quickly if your earnings drop. Again, taxes on your earnings remain the same; only the benefit payment rules change.

Common mistakes to avoid

The most common mistake is not reporting earnings to Social Security on time. Even if you think your income is low enough that it will not affect your benefit, report it anyway. Social Security uses the reports to track your TWP progress and to verify your income when you file your tax return.

Another mistake is assuming SSDI is taxable and overpaying. Many beneficiaries do not realize that combined income must exceed the threshold before any SSDI is taxable. If you earn $20,000 and receive $12,000 in SSDI, you may owe no tax on the SSDI itself — only on the wages. Use the combined income formula to check before you file.

A third mistake is not setting aside money for taxes. SSDI does not have tax withholding, so if you earn significant wages or self-employment income, you need to save enough to cover your tax bill. Many beneficiaries are surprised by a large bill at tax time because they spent all their income and did not plan for taxes.

Frequently Asked Questions

Do I have to file a tax return if I am on SSDI during my Trial Work Period?

You must file if your total income (SSDI plus wages or self-employment income) exceeds the standard filing threshold for your age and filing status. For 2024, the threshold is $14,600 for a single person under 65. Even if you do not owe tax, filing may allow you to claim the Earned Income Tax Credit or other refundable credits. Check the IRS website or ask a tax professional to be sure.

Can I claim the Earned Income Tax Credit while on SSDI?

Yes, if your earned income and adjusted gross income are below the EITC limit for your filing status and number of dependents. For 2024, the limit ranges from about $43,000 to $60,000 depending on your situation. SSDI itself does not count as earned income, but wages and self-employment income do. The EITC can result in a refund even if you owe no tax.

What if I earn money but do not report it to Social Security?

Social Security may discover the unreported income when you file your tax return or through other means. If you received SSDI payments you were not may have access to to because of unreported earnings, Social Security will send an overpayment notice and may recover the money by reducing future payments. Reporting on time protects you and keeps your TWP on track.

Do I owe self-employment tax if I earn less than $400 during my Trial Work Period?

No. Self-employment tax is required only if your net self-employment income is $400 or more in a year. If you earn $300 in self-employment income, you do not owe self-employment tax, but you still must report the earnings to Social Security and include them in your combined income calculation for SSDI taxability purposes.

Will my SSDI payment be reduced if I earn a lot during the Trial Work Period?

No. The entire point of the TWP is that earnings do not reduce your SSDI payment, no matter how much you earn. Your payment stays the same every month. However, you must report the earnings to Social Security, and those earnings will affect your federal income tax bill and may make part of your SSDI taxable.
