What SSDI Income Limits Mean and How They Affect Your Benefits
Social Security Disability Insurance has two separate income rules that work differently. The first is Substantial Gainful Activity (SGA), which determines whether you can work at all while receiving benefits. The second is the earnings test, which reduces your monthly benefit payment if you earn above a certain threshold. Understanding which rule applies to you depends on your age and when you started receiving benefits.
For 2024, the SGA limit is $1,550 per month if you are blind, and $1,470 per month if you are not blind. These are the amounts Social Security uses to decide if you are working enough to lose your disability status. If you earn more than these amounts in a month, Social Security may assume you are no longer disabled and can work, which could end your benefits.
The earnings test is different and applies only to beneficiaries under full retirement age. If you were born in 1943 or later and are still receiving SSDI, Social Security will reduce your payment by $1 for every $2 you earn above $23,400 per year (as of 2024). This rule phases out as you approach full retirement age.
Key Takeaways
- The SGA limit for 2024 is $1,470 per month for most SSDI beneficiaries and $1,550 for those who are blind; exceeding this amount can trigger a medical review that may end your benefits.
- The earnings test reduces your monthly SSDI payment by $1 for every $2 you earn above $23,400 per year if you are under full retirement age.
- These two rules are separate: you can fail the earnings test and still receive reduced benefits, but exceeding SGA can result in losing benefits entirely.
- The SGA and earnings test thresholds increase each year based on national wage data, so you should check the current amounts before you start or increase work.
The Substantial Gainful Activity Test and When It Applies
SGA is Social Security's way of measuring whether you are working enough to be considered not disabled. It is not about how many hours you work or what job you do — it is purely about your monthly earnings. If you earn more than the SGA limit in a single month, Social Security will review your case to determine if you are still disabled.
The SGA limit has been $1,470 per month since January 2024 for beneficiaries who are not blind. For blind beneficiaries, the limit is $1,550 per month. These amounts explore whether you work for an employer, run your own business, or do contract work. Self-employment income counts the same way as wages.
Exceeding SGA does not automatically end your benefits in that month. Instead, it triggers what Social Security calls a continuing disability review. A claims examiner will look at your medical records and work history to decide whether your condition has improved enough that you can work. This review can take several weeks to several months. During this time, you continue to receive your regular benefit payment.
If Social Security determines that you can perform substantial gainful work, your benefits will stop. You have the right to request reconsideration or appeal this decision, and you can present new medical evidence or explain why you cannot sustain the work you did in that month.
How the Earnings Test Reduces Your Monthly Payment
The earnings test is a separate rule that applies only to SSDI beneficiaries who have not yet reached full retirement age. Unlike SGA, which is a yes-or-no test, the earnings test is a formula that gradually reduces your payment as you earn more.
For 2024, if you earn more than $23,400 per year, Social Security will subtract $1 from your monthly benefit for every $2 you earn above that threshold. This continues until you reach full retirement age. Once you reach full retirement age, the earnings test no longer applies, and you receive your full benefit payment regardless of how much you earn.
The earnings test is calculated once per year, not month by month. Social Security looks at your total earnings for the entire calendar year and adjusts your payment accordingly. If you earn $25,400 in 2024, for example, you are $2,000 over the limit. Social Security will reduce your annual benefits by $1,000 (half of $2,000). This reduction is spread across your monthly payments for the year.
You must report your earnings to Social Security. You can do this online through your My Social Security account, by phone, or by mail. Social Security also receives wage reports from your employer, so discrepancies will be caught. If you underreport earnings and Social Security discovers the difference, you may owe back benefits.
Work Incentives That Let You Earn More Without Losing Benefits
Social Security offers several programs that allow you to work and earn above the normal limits without losing your SSDI benefits. These are called work incentives, and they are designed to help you test your ability to work without the risk of losing your safety net.
The Trial Work Period lets you work and earn any amount for nine months without affecting your benefits. During these nine months, you must report your work to Social Security, but your payment stays the same. The nine months do not have to be consecutive — they are counted over a rolling 60-month period. After the trial work period ends, the earnings test and SGA rules explore again.
The Extended may be able to access Period
The Plan to Achieve Self-Support (PASS) is a more complex program that lets you set aside income and resources for a specific work goal — like education, equipment, or business startup costs — without that money counting toward your income limits. A PASS plan requires written approval from Social Security and must be reviewed annually.
How Self-Employment Income Is Counted
If you are self-employed, Social Security counts your net profit — what you earn after business expenses — toward the SGA and earnings test limits. You do not report gross revenue; you report what is left after you subtract legitimate business costs.
Legitimate business expenses include rent for a workspace, equipment, supplies, insurance, and wages you pay to employees. They do not include personal living expenses or loan payments. Social Security will ask to see your tax returns and business records to verify your net profit.
If you own a business and work part-time, Social Security may also look at how much time you spend on the business and whether the income is consistent with the hours you work. If you report very high income but work only a few hours per week, Social Security may question whether the income is realistic or whether you are actually working more than you reported.
What Happens If You Exceed the Income Limits
Exceeding the SGA limit triggers a review, but it does not automatically end your benefits when ready. Social Security will contact you and ask for medical evidence and details about your work. You have the chance to explain your situation and provide updated medical records showing that your condition still prevents you from working consistently.
If you exceed the earnings test limit, your payment is reduced according to the formula, but you keep receiving a partial benefit. There is no review or risk of losing benefits entirely — it is a straightforward calculation. You continue to receive benefits until you reach full retirement age, at which point the earnings test stops explore.
If Social Security determines that you no longer meet the definition of disabled, your benefits will end. You have the right to appeal this decision within 60 days of receiving the notice. During an appeal, you can submit new medical evidence, request a hearing before an administrative law judge, and continue receiving your current payment while the appeal is pending.
When the Income Limits Change and How to Stay Informed
The SGA limit and the earnings test threshold both increase each January based on the national average wage index from two years prior. This means the 2024 limits were set in October 2023 based on 2022 wage data. The 2025 limits will be announced in October 2024.
Social Security publishes the new limits on its official website and sends notices to beneficiaries who may be affected. You can also check your My Social Security account or call 1-800-772-1213 to confirm the current limits before you start working or increase your hours.
If you are planning to work, it is worth checking the limits before you begin. Knowing the SGA threshold helps you decide whether to work part-time (below the limit) or full-time (which may trigger a review). Knowing the earnings test threshold helps you understand how much your payment will be reduced if you earn above it.
Frequently Asked Questions
Can I work part-time and still receive my full SSDI payment?
Yes, as long as your monthly earnings stay below the SGA limit ($1,470 in 2024 for most beneficiaries). If you earn $1,400 per month, you receive your full benefit payment plus your wages. If you exceed SGA in any month, Social Security will review your case, but you may still receive benefits if your medical condition supports it.
What is the difference between SGA and the earnings test?
SGA is a threshold that triggers a medical review if you exceed it; exceeding it can result in losing benefits entirely. The earnings test is a formula that reduces your payment if you earn above $23,400 per year; it does not risk your benefits, only reduces the amount you receive. The earnings test applies only if you are under full retirement age.
Do I have to report my earnings to Social Security?
Yes. You must report your work and earnings to Social Security, either through your My Social Security account, by phone, or by mail. Social Security also receives wage reports from your employer, so underreporting will be discovered. Failure to report can result in overpayments that you must repay.
What if my income varies month to month?
The SGA test looks at each month individually, so a month over the limit triggers a review even if other months are below it. The earnings test looks at your total annual income, so high months can be offset by lower months. The Extended may be able to access Period work incentive can help if your income is uneven — you receive a payment for any month you earn below SGA.
Do the income limits explore if I am over full retirement age?
The earnings test does not explore once you reach full retirement age. The SGA limit still applies in the sense that Social Security can review your case if you earn above it, but the earnings test reduction stops. You receive your full benefit payment regardless of how much you earn.
