SGA is the income limit that decides whether Social Security counts you as working

SGA stands for Substantial Gainful Activity. It is a dollar amount set by Social Security each year. If you earn more than that amount per month, Social Security treats you as working — even if you say you are not trying to work, even if you work part-time, even if you work from home.

Why this matters: if you are receiving SSDI (Social Security Disability Insurance) and your earnings cross the SGA line, Social Security can stop your benefits. The threshold changes every January, so the number that applied last year may not explore this year.

SGA is not the same as the earnings limit for Supplemental Security Income (SSI). SSDI and SSI are separate programs with different rules. This article covers SSDI only.

Key Takeaways

  • SGA is a monthly income threshold; if you earn more than that amount, Social Security may view you as working and reduce or stop your SSDI payments.
  • The SGA amount changes each January and is different for blind beneficiaries than for other beneficiaries.
  • Earnings include wages, net profit from self-employment, and some other forms of income, but do not include certain work incentives like Plans to Achieve Self-Support (PASS).
  • You must report your earnings to Social Security; they do not automatically know what you earn, and failing to report can result in overpayment and a debt you must repay.
  • Crossing the SGA threshold does not when ready end your benefits — there are trial work periods and other rules that may protect your payments temporarily.

The SGA dollar amount for 2024 and how it changes

For 2024, the SGA amount is $1,550 per month for most beneficiaries. For beneficiaries who are blind, it is $2,590 per month. These numbers are set by federal law and change only once per year, in January.

Social Security bases the SGA amount on the national average wage index from two years prior. Because wages rise over time, the SGA threshold generally increases each year, though the increase is usually small — often $50 to $150. You can find the current year's SGA amount on the Social Security website or by calling 1-800-772-1213.

The SGA amount applies to all states the same way. It does not vary by where you live or by the type of work you do.

What counts as earnings under SGA

Social Security counts most money you receive for work as earnings. This includes:

  • Wages from an employer (before taxes are taken out)
  • Net profit from self-employment (income minus business expenses)
  • Royalties and honorariums
  • Sheltered workshop income

Some forms of income do not count toward SGA. These include:

  • Unearned income like pensions, interest, rental income, or gifts
  • Impairment-Related Work Expenses (IRWE) — costs you pay to work because of your disability, such as special transportation or medical equipment
  • Plans to Achieve Self-Support (PASS) — money you set aside to reach a work goal
  • Earnings from certain work incentive programs

The distinction matters because only earned income counts. If you receive $2,000 per month in disability pension and $500 in wages, only the $500 counts toward SGA.

How Social Security uses SGA to make decisions about your benefits

If your monthly earnings stay below the SGA amount, Social Security assumes you are not working at a substantial level. Your SSDI payments continue without interruption, regardless of how many hours you work or how hard you try.

If your monthly earnings go above the SGA amount, Social Security views you as engaged in substantial gainful activity. This does not automatically stop your benefits when ready — there are protections built in — but it signals to Social Security that your case needs review.

The key protections are the trial work period and the grace period. During the trial work period, you can earn any amount and keep your full SSDI payment for up to nine months in a rolling 60-month window. After the trial work period ends, if you continue to earn above SGA, your benefits will stop. The grace period gives you one additional month of full payment even if you earn above SGA during that month.

After your benefits stop, you enter what Social Security calls the extended period of may be able to access. During this time, you can work and earn above SGA for up to 36 months, and your benefits will turn back on automatically in any month you earn below SGA again.

How to report your earnings to Social Security

You are responsible for telling Social Security about your earnings. They do not receive this information automatically from your employer or from tax records. You must report:

  • The month you started working
  • Your gross monthly earnings (before taxes)
  • The name and address of your employer, or details of your self-employment

You can report earnings by phone at 1-800-772-1213, by visiting your local Social Security office, or through your online my Social Security account. Report as soon as you start working or as soon as your earnings change. Do not wait until tax time.

If you do not report earnings and Social Security later discovers you were working, you may owe back a portion of the benefits you received. This debt is called an overpayment, and Social Security will ask you to repay it — usually by reducing your future benefits month by month.

What happens if you earn above SGA

Earning above the SGA threshold does not mean your benefits stop that same month. The timeline depends on where you are in your work history with SSDI.

If you have not yet used your trial work period, you can earn any amount for up to nine months and keep your full payment. Social Security counts any month in which you earn $1,050 or more (for 2024) as a trial work month, regardless of how much you actually earn.

Once you have used nine trial work months, the next month you earn above SGA, your payment is reduced. After a grace period of one additional month, your benefits stop if you continue to earn above SGA.

The extended period of may be able to access then kicks in. For the next 36 months, your benefits will restart automatically in any month you earn below SGA, even if you earned above it the month before. This gives you a chance to test your ability to work without permanently losing your safety net.

SGA and work incentives you should know about

Social Security offers several work incentives designed to let you earn money without losing benefits. These are separate from the SGA rule and can help you work more while keeping some or all of your payment.

Impairment-Related Work Expenses (IRWE) let you subtract certain disability-related costs from your earnings before Social Security counts them toward SGA. If you need a personal assistant, special transportation, or medical equipment to work, these costs may reduce your countable earnings.

Plans to Achieve Self-Support (PASS) let you set aside income and resources to reach a specific work goal — like paying for training or buying tools. Money in a PASS plan does not count as earnings and does not affect your benefits.

Impairment-Related Expenses (IRE) and Plans for Achieving Self-Support for Blind Individuals are variations with slightly different rules for blind beneficiaries.

To use these work incentives, you usually need to set them up in advance with Social Security. Ask your local Social Security office or call 1-800-772-1213 to learn whether any of these might help your situation.

Frequently Asked Questions

What if I earn $1,600 one month but $1,400 the next — does that count as above SGA?

Social Security looks at each month separately. The month you earn $1,600 counts as above SGA (assuming 2024 rates). The month you earn $1,400 counts as below SGA. Your benefits are based on what you earn in each individual month, not an average across months.

Do I lose all my benefits the month I go over SGA?

Not necessarily. If you have not used your trial work period, you can earn any amount and keep your full payment for up to nine trial work months. After that, benefits are reduced or stopped depending on how much you earn and which grace period you are in. The exact timing depends on your work history with SSDI.

What if I am self-employed — how do I calculate my earnings for SGA?

For self-employment, Social Security counts your net profit: total income minus reasonable business expenses. Keep records of both. If you are unsure what counts as a business expense, ask Social Security before you report, because they may question expenses later.

Can I work during the trial work period without telling Social Security?

No. You must report your earnings even during the trial work period. Social Security uses your reports to count down your nine trial work months. If you do not report and they find out later, you may owe an overpayment.

Does SGA explore if I am on SSI instead of SSDI?

No. SSI has its own earnings rules and does not use SGA. If you receive SSI, contact Social Security about the SSI earnings limit, which is different. This article covers SSDI only.
