The 2024 Substantial Gainful Activity threshold is $1,550 per month

In 2024, the Substantial Gainful Activity (SGA) limit — the income ceiling that determines whether you are considered to be working — is $1,550 per month for non-blind beneficiaries. This means that if you earn more than $1,550 in a month from work, Social Security will assume you are working at a substantial level and may suspend your benefits for that month, even if you have a disability.

For beneficiaries who are blind, the 2024 SGA limit is higher: $2,590 per month. This higher threshold reflects a longstanding policy that recognizes the additional costs blind workers often face when working.

These figures change each year because Social Security adjusts them based on the national average wage index. The 2024 amounts represent an increase from 2023, when the non-blind limit was $1,470 and the blind limit was $2,460.

Key Takeaways

  • If you earn more than $1,550 in a single month, Social Security will count that month as a month of work, which can affect your benefits.
  • The SGA limit applies to your gross earnings before taxes, not your take-home pay.
  • Blind beneficiaries have a separate, higher SGA limit of $2,590 per month in 2024.
  • Staying under the SGA limit does not automatically mean you keep your full benefit — other income rules and work incentives also explore.
  • Social Security publishes updated SGA amounts each year in November, effective the following January.

How the SGA limit affects your monthly benefits

The SGA limit is a threshold, not a gradual reduction. If you earn $1,550 or less in a month, that month does not count as a month of work for benefit purposes. If you earn $1,551 or more, Social Security counts it as a month in which you worked, and your benefit for that month may be suspended.

This is different from how other income (such as interest, rental income, or unearned money) affects your benefits. Unearned income does not trigger the SGA rule. Only work earnings matter for the SGA threshold.

The rule applies to your gross earnings — the amount before taxes, deductions, or other withholdings. If you are self-employed, Social Security counts your net profit (revenue minus business expenses) as your earnings.

The trial work period and SGA

Social Security offers a trial work period that lets you test your ability to work without losing benefits. During the nine-month trial work period, you can earn any amount and keep your full SSDI benefit. The trial work period does not depend on the SGA limit.

After your trial work period ends, the SGA limit becomes the main rule. If you earn above SGA in any month after the trial work period, that month counts as a work month. Once you have accumulated nine work months (not necessarily consecutive) in a 60-month window, your benefits will end.

This structure means the SGA limit is most relevant after your trial work period closes. During the trial work period itself, you can earn above $1,550 with no effect on your benefits.

Self-employment and the SGA limit

If you are self-employed, the SGA limit still applies, but Social Security calculates your earnings differently. You report your net profit — total revenue minus ordinary and necessary business expenses — rather than gross revenue.

Self-employed beneficiaries also have an alternative test called the expedited reinstatement of benefits rule. If your self-employment business fails or you stop working, you may be able to restart your benefits without going through the full medical review again, as long as you request reinstatement within five years.

Keep records of all business expenses, receipts, and profit-and-loss statements. Social Security will ask for these documents if your earnings approach or exceed the SGA limit.

What happens if you exceed the SGA limit

If you earn more than $1,550 in a month, Social Security will not automatically stop your benefits that same month. Instead, the agency counts that month as a work month. Your benefits continue until you have accumulated enough work months to trigger the end of your benefits under the rules that follow your trial work period.

You are required to report your earnings to Social Security. You can report them online through your my Social Security account, by phone at 1-800-772-1213, or in person at your local Social Security office. Failing to report earnings can result in overpayments that you will have to repay.

If you receive an overpayment notice, you have the right to request a waiver or to appeal. Social Security may forgive overpayments in some cases if you were not at fault for the error.

Other income limits that interact with SGA

The SGA limit is separate from the Student Earned Income Exclusion, which allows students under age 22 to exclude up to $2,170 per month in 2024 (or $8,680 in annual earnings) from the SGA calculation. If you are a student, you may be able to earn above the SGA limit without it counting as work.

SSDI also has work incentive programs — such as Impairment Related Work Expenses (IRWE), Plans to Achieve Self-Support (PASS), and the Student Earned Income Exclusion — that can reduce your countable earnings below the SGA limit even if your gross earnings are higher. These programs are designed to encourage work without when ready ending your benefits.

If you receive both SSDI and Supplemental Security Income (SSI), you may be subject to different income rules. SSI has its own income limits and counting rules that are separate from the SSDI SGA threshold.

Planning your work around the SGA limit

If you are working or considering work, understanding the SGA limit helps you plan. Many beneficiaries stay intentionally below the limit to keep their benefits while earning some income. Others use the trial work period to test whether they can work full-time, knowing they have nine months to do so without losing benefits.

Some beneficiaries work part-time or seasonally to stay under $1,550 per month. Others use work incentive programs to reduce their countable earnings. The right strategy depends on your health, your job, and how much you need your SSDI benefit.

If you are unsure whether a job or income will affect your benefits, contact Social Security before you start work. The agency can explain how your specific situation interacts with the SGA limit and other rules.

Frequently Asked Questions

Does the SGA limit include tips, bonuses, or irregular income?

Yes. Social Security counts all work earnings, including tips, bonuses, commissions, and irregular payments. If you receive a large bonus in one month that pushes your earnings above $1,550, that month counts as a work month for SGA purposes, even if your usual monthly earnings are lower.

What if I work for a family member or volunteer?

If you are paid for work — even by a family member — the SGA limit applies. Unpaid volunteer work does not count as earnings and does not affect your benefits. If you are unsure whether an arrangement counts as paid work, ask Social Security before you begin.

Can I use work incentives to stay under the SGA limit?

Yes. Programs like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) can reduce your countable earnings. For example, if you earn $2,000 but have $600 in work-related disability expenses, your countable earnings may be $1,400, which is below SGA. You must document these expenses and have them approved by Social Security.

What if I earn above SGA for one month but below it the next month?

Each month is counted separately. If you earn $1,551 in January and $1,200 in February, January counts as a work month and February does not. You accumulate work months over time; once you reach nine work months in a 60-month window, your benefits end. Months below SGA do not count toward this total.

Does the SGA limit change if I move to a different state?

No. The SGA limit is set by the federal government and applies the same way in every state. Your state of residence does not affect the $1,550 threshold for 2024.
