Work Limits for Disability Benefits in Maryland, Virginia and D.C.

When health problems make it hard or impossible to work, Social Security Disability benefits help cover basic living expenses. Benefits provide stability during a difficult time.

One of the key standards Social Security uses to decide who qualifies is called “substantial gainful activity,” otherwise known as SGA.

Substantial gainful activity is the level of work and income from work that Social Security uses to help decide whether you need disability benefits. If you’re under their SGA limit, you could be eligible for benefits. Over SGA, you’ll likely be denied.

To determine whether you’re at SGA, they look at how much money you earn through work and, in some cases, the kind of work you are doing.

This rule applies when you first apply for disability benefits, but it also matters after you are approved and they review whether you should keep receiving benefits.

For people in Maryland, Virginia and Washington, D.C., understanding how substantial gainful activity works is important when you’re trying to get disability benefits.

Substantial Gainful Activity: How Much Can You Earn?

Social Security sets a monthly income limit each year to decide whether someone is engaging in substantial gainful activity.

If your countable income goes over that amount, Social Security may decide you are able to work too much to qualify for disability benefits.

The main goal of disability benefits is to help people who can’t work enough to support themselves.

As of 2026, the SGA limits were set at:

$1,690 per month for most individuals

$2,830 per month for individuals who are legally blind

You can’t be making more than those amounts and still expect to be approved for benefits.

The limits apply when you’re applying for benefits and after you’re approved. Going over the substantial gainful activity limit in any month can affect your pending claim or ongoing benefits you already receive.

When Social Security looks at income for substantial gainful activity, they usually start with your gross monthly earnings.

If you’re self-employed, they may also look at your net income and the value of the work you perform, not just the money you take home. In some cases, work expenses related to your health impairments may reduce how much income Social Security counts.

The rules can be hard to understand. Because of this, many people go over the substantial gainful activity limit without realizing it.

It’s perfectly understandable to want to work at least a little bit to help make ends meet when your household budget is strained. But you need to make sure it doesn’t jeopardize other help.

The disability advocates at Mathis & Mathis can help you understand how working affects your disability claim.

You Can Sometimes Keep Disability Benefits and Earn more than SGA

Social Security allows people to work more while receiving disability benefits in certain cases, but the rules can be confusing.

Trial Work Periods

If you receive Social Security Disability Insurance (SSDI), you may qualify for something called a “trial work period.” This allows you to try working for up to nine months without immediately losing your disability benefits.

The nine months do not have to be in a row. As of 2026, a month usually counts toward a trial work period if you earn at least $1,210. During this time, you can earn more than the substantial gainful activity limit and still receive your full SSDI check.

Extended Period of Eligibility

After you use your nine months of trial work period, Social Security gives you a 36-month “extended period of eligibility.”

During this time, you continue getting disability benefits in months when your earnings stay below the SGA limit, but you don’t receive benefits in months when your income rises above SGA.

Social Security may also look at the type of work you are doing, such as how physical it is, how mentally demanding it is, and whether it looks like work you can do on a regular basis.

These same issues can come up later during a “continuing disability review,” when they check if you should still keep getting benefits after several years.

Dealing with serious health problems and piecing together the money you need to stay afloat makes this one of the hardest times in your life.

You deserve personal care and attention to navigate these programs. At Mathis & Mathis Disability Advocates, we treat you like a human being, not a case number. We help people win benefits, and we’re still here when questions come up later about work, payments or reviews.
