Your SSDI payment shrinks when you earn above a certain threshold

The Social Security Administration uses a formula called substantial gainful activity (SGA) to decide whether your work reduces your benefit. If you earn more than the SGA limit in a month, Social Security counts that month as a work month. Once you have nine work months in a rolling 60-month period, your benefits stop entirely — not when ready, but after a grace period called the trial work period ends.

The SGA limit changes each year. For 2024, the limit is $1,550 per month if you are blind, and $1,470 per month if you are not blind. These numbers are set by federal law and explore nationwide. Your state does not adjust them. If you earn less than the limit in a given month, that month does not count toward the nine-month threshold, even if you work multiple jobs or have other income.

The key word is earn, not receive. Social Security looks at your gross wages before taxes, not what hits your bank account. Self-employment income is calculated differently — you report net profit (income minus business expenses) rather than gross revenue.

Key Takeaways

  • Earning more than $1,470 per month (or $1,550 if blind) counts as a work month toward losing your benefits after nine such months in 60 months.
  • The trial work period lets you test your ability to work for nine months without losing benefits, but you must report all earnings to Social Security.
  • After the trial work period ends, your benefits stop if you have had nine work months, but you can restart them if earnings drop below the SGA limit again.
  • Self-employment income is calculated on net profit, and you must report it even if you have not yet filed taxes.
  • Social Security counts only months in which you earned above the limit; months below the limit do not count, even if you worked.

The trial work period: nine months to test your work capacity

When you first return to work, you enter a trial work period that lasts nine months. During these nine months, you keep your full SSDI payment no matter how much you earn. Social Security does not reduce your check based on earnings during the trial work period. The only requirement is that you report your earnings to Social Security each month.

The nine months do not have to be consecutive. A trial work month is any month in which you earn $1,050 or more (for 2024). If you earn less than $1,050 in a month, that month does not count toward the nine. So if you work part-time one month and earn $800, then take a month off, then work again, only the months above $1,050 count. You could stretch a trial work period across a year or longer if your earnings are uneven.

After you complete nine trial work months, you enter a grace period that lasts the rest of the month you crossed the nine-month threshold, plus the next two months. During the grace period, you still receive your full benefit even if you earn above the SGA limit. After the grace period ends, the nine-month count resets, and any month in which you earn above the SGA limit ($1,470 for non-blind recipients) counts as a work month again.

What happens after the grace period: the nine-month countdown

Once your grace period ends, Social Security begins counting work months again. A work month is any month in which you earn $1,470 or more (for 2024, non-blind). You can have up to nine work months before your benefits stop. These nine months do not have to be consecutive — they accumulate over a rolling 60-month window.

When you reach your ninth work month, your benefits do not stop when ready. Instead, they stop the month after your ninth work month ends. For example, if your ninth work month is March, your benefits stop in April. You receive a notice before this happens, usually 30 to 60 days in advance.

If you drop below the SGA limit ($1,470) in a month, that month does not count as a work month, and the count does not advance. You can stay below the limit indefinitely without losing benefits. The nine-month threshold only applies if you cross the SGA limit.

Restarting benefits after work stops or earnings drop

If your benefits stopped because you had nine work months, you can restart them without reapplying. You must report to Social Security that your earnings have dropped below the SGA limit. Once you report the drop, Social Security will restart your benefits the month after you fall below the limit. You do not have to wait for a new decision or a new medical review — the restart is automatic if you were previously approved.

The nine-month count resets when your benefits restart. You get another trial work period and another grace period. This means you can cycle between work and benefits multiple times over your lifetime, as long as your medical condition still meets the disability standard. Social Security does not penalize you for stopping work and restarting benefits.

If you are unsure whether your earnings have dropped below the SGA limit, report the change to Social Security anyway. It is better to report and have them confirm the amount than to miss the restart window. You can report earnings changes by phone, mail, or through your online My Social Security account.

Self-employment income and how it is counted

If you are self-employed, Social Security counts your net profit — what you keep after business expenses — not your gross revenue. You report net profit on your tax return (Schedule C for sole proprietors), and you must report the same figure to Social Security. If you have not filed taxes yet, you can estimate your net profit based on your business records and report that to Social Security. You will reconcile the number later when your taxes are filed.

Business expenses include rent, supplies, equipment, utilities, and wages you pay to employees. They do not include your own salary or drawings — those are not expenses. If you are unsure what counts as a business expense, keep records of all spending and ask a tax preparer or accountant. Social Security will ask to see your tax return or business records if your self-employment income is close to the SGA limit.

Self-employment income is also subject to the trial work period and the nine-month countdown. A month in which your net profit exceeds $1,470 counts as a work month. Months below that do not count, even if you worked the entire month.

Reporting earnings and avoiding overpayments

You are required to report all earnings to Social Security within the month they occur. You can report by phone at 1-800-772-1213, by mail using form SSA-777 (Report of Earnings), or through your My Social Security account online. If you miss a reporting important date, Social Security may overpay you — meaning you received benefits you were not may have access to to — and you will have to repay the overpayment later.

Overpayments can be large. If Social Security paid you for three months when you should have lost benefits, you owe three months of payments back. The agency can recover overpayments by reducing your future benefits, taking tax refunds, or asking you to repay in installments. Reporting on time prevents this.

If you are working and unsure whether you need to report, report anyway. Social Security would rather receive extra reports than miss an earnings change. There is no penalty for over-reporting.

Work incentives that reduce the SGA impact

Social Security offers several work incentive programs that let you keep more of your benefit while working. The most common is Impairment Related Work Expenses (IRWE), which lets you deduct certain costs related to your disability from your earnings before Social Security calculates whether you crossed the SGA limit. For example, if you need a personal assistant to help you get to work, or special equipment, or medication related to your disability, you may be able to deduct those costs.

Another program is Plans to Achieve Self-Support (PASS), which lets you set aside income and resources for a specific work goal — like training for a new job or starting a business — without it counting against your benefits. PASS requires a written plan and approval from Social Security, but it can protect a significant portion of your earnings.

These programs are complex and require documentation. Ask your local Social Security office or a work incentives planning and information (WIPA) project for help. WIPA services are free and available in every state.

Frequently Asked Questions

Do I lose all my benefits the month I reach nine work months?

No. Your benefits stop the month after your ninth work month ends. For example, if you have your ninth work month in June, your benefits stop in July. You receive a notice before the stop date.

What if I work part-time and earn $800 one month and $1,600 the next?

Only the month you earned $1,600 counts as a work month. The $800 month does not count. If you alternate between high and low earnings, only the high-earning months count toward your nine-month threshold.

Can I restart my benefits if I stop working?

Yes. If your benefits stopped because of nine work months, you can restart them by reporting that your earnings dropped below the SGA limit ($1,470 for non-blind recipients). Benefits restart the month after you fall below the limit, and you do not need a new medical review.

Do I have to report earnings if I am still in my trial work period?

Yes. You must report all earnings during the trial work period, even though your benefits do not change. Reporting is required so Social Security can track which months count toward your nine-month threshold after the trial work period ends.

How do I know if my business expenses are deductible from my self-employment income?

Business expenses are costs you incur to run your business — rent, supplies, equipment, utilities, and employee wages. They do not include your own income or personal expenses. If you are unsure, ask a tax preparer or contact your local WIPA project for guidance.
