You got the job. The first paycheck arrives, and the number is smaller than you expected. Taxes, deductions, and acronyms fill the stub. Your caseworker mentioned reporting income, but you're not sure when or how. A friend said something about gross versus net, and you nodded along.

Opening that envelope means knowing what you're looking at and what to do next.

Understanding Your Paycheck

Your pay stub has two numbers that matter most: gross pay and net pay. Gross is what you earned before anything comes out. Net is what hits your bank account. The difference is where confusion starts.

Gross pay is your hours multiplied by your hourly rate. If you worked 20 hours at $15 per hour, your gross is $300. That's the number your employer reports to the IRS and Social Security Administration. It's also the number SSI uses to calculate your benefit reduction, not the net amount you take home.

Net pay is what remains after deductions. Federal income tax, state income tax (if your state has one), Social Security tax (FICA), Medicare tax, and any voluntary deductions like health insurance premiums. For someone earning $300 gross, net might be $240 after taxes and FICA. That $60 difference matters when you're budgeting.

What Each Deduction Means

Federal income tax: withheld based on the W-4 form you filled out when you started. If you're earning part-time wages, you may owe little to no federal tax, and you'll get most of this back at tax time if your employer overwitheld.

FICA (Social Security and Medicare taxes): 7.65% of your gross pay. This funds Social Security and Medicare. You can't opt out, and you won't get it back at tax time. If you're receiving SSDI, you're still paying into the system through work. If you're on SSI, FICA comes out regardless.

State and local taxes: depend on where you live. Nine states have no income tax. Others withhold a percentage. Check your stub to see if this line appears.

Voluntary deductions: health insurance, retirement contributions, union dues. These only show up if you elected them. If a deduction appears that you don't recognize, ask your employer's payroll department. Don't assume it's correct.

How Work Income Affects Disability Benefits

This is where competence matters more than anywhere else. Misunderstanding how employment affects SSI or SSDI can result in overpayments you're required to repay, sometimes years later.

If You're on SSI

SSI has strict income rules. The program reduces your benefit by $1 for every $2 you earn above $85 per month (as of 2026). The calculation uses your gross wages, not your net pay. That $300 gross paycheck reduces your SSI by $107.50, even though you only took home $240.

You must report your earnings to Social Security within 10 days of receiving your first paycheck, and then continue reporting monthly. The math changes month-to-month based on what you earned, and if they find out late, you get a bill for overpayment you've already spent.

Some income doesn't count. Social Security excludes the first $20 of any income, and then excludes the first $65 of earned income. After that, the $1-for-$2 reduction kicks in. If your state has a state supplement to SSI, different rules may apply. Call your local SSA office or ask your benefits counselor to walk through the calculation using your actual wages.

If You're on SSDI

SSDI doesn't reduce benefits dollar-for-dollar the way SSI does. Instead, it uses a threshold called Substantial Gainful Activity (SGA). In 2026, SGA is $1,550 per month for non-blind individuals and $2,590 for blind individuals. Earn less than that, and your SSDI continues unchanged. Earn more, and your benefits stop after a trial work period.

The trial work period lets you test employment for nine months (not necessarily consecutive) within a 60-month rolling window. During those months, you receive full SSDI regardless of earnings. After the trial work period ends, if you're still earning above SGA, benefits stop. If your earnings drop below SGA within the next 36 months, benefits restart without reapplying.

This structure means you need to track your hours and gross pay carefully. A few months of overtime that push you above SGA can trigger benefit termination if you're past your trial work period. Your caseworker needs to know about your job within 10 days of your first paycheck so they can start the trial work period clock and explain what happens next.

Building a Budget on Variable Income

Many entry-level jobs offer variable hours. You work 15 hours one week, 25 the next. Your paycheck swings between $180 and $375. Budgeting on fixed income is straightforward. Budgeting on variable income requires a different approach.

Start With Your Lowest Expected Monthly Income

Look at your last three months of paychecks. What was your lowest gross pay in a single month? That's your baseline. Build your budget assuming that amount, not your highest month or an average. If your lowest month was $600 and your highest was $1,100, budget for $600.

This approach ensures your essential expenses (rent, utilities, food, transportation) are covered even in a light-earning month. Anything above $600 goes into savings or discretionary spending, not fixed commitments.

Separate Needs from Wants

Needs: rent, utilities, food, transportation, medications, phone. Wants: streaming services, dining out, new clothes. When income varies, wants get funded only after needs are covered and a small buffer is saved.

If your baseline income is $600 and your needs total $550, you have $50 left. That $50 doesn't go to a new subscription. It goes into savings until you have $200-$300 set aside for the month your hours get cut or you're sick and miss a week.

Track Spending for Two Months Before Making Changes

Budgeting starts with knowing where money goes, not where you think it goes. For two months, write down or photograph every purchase. At the end of the second month, categorize: food, transportation, entertainment, personal care, other. You'll see patterns. Coffee adds up. So do app purchases and convenience store snacks.

Don't judge the spending yet. Just observe it. Then decide what to keep and what to cut based on your actual baseline income, not your aspirational one.

Taxes and Filing

If you earn wages, you'll receive a W-2 form by January 31 of the following year. That form shows your total gross wages, federal tax withheld, FICA withheld, and state tax withheld (if applicable). You'll need it to file your tax return.

Many people with disabilities earning part-time wages owe no federal income tax after taking the standard deduction. For 2026, the standard deduction for a single filer is $14,600. If you earned $8,000 in wages, you owe no federal tax and should get back whatever was withheld.

Free tax preparation is available through the IRS Volunteer Income Tax Assistance (VITA) program for people earning under $64,000 annually. VITA sites are staffed by IRS-certified volunteers who prepare returns at no cost. Find a site near you at irs.gov/vita or call 1-800-906-9887.

If you're on SSI or SSDI and work, you may qualify for the Earned Income Tax Credit (EITC), a refundable credit that can add $600-$7,800 to your refund depending on your income and family size. VITA preparers can determine eligibility and file the claim for you.

What to Ask Your Employer or Job Coach

You're not expected to know everything before you start. These are the questions worth asking during your first week:

• How do I access my pay stubs? (Online portal, paper, direct deposit notification?)
• What's the pay schedule? (Weekly, biweekly, semi-monthly?)
• Who do I contact if a deduction looks wrong or if my hours don't match my stub?
• Does the company offer direct deposit, and how do I set it up?
• If my schedule changes, when will I know my hours for the next pay period?

If you have a job coach or supported employment counselor, bring your first pay stub to your next meeting and walk through it together. They should be able to explain each line and help you set up a reporting routine with Social Security if needed.

When to Get Help

You don't need to do this alone. If any of the following apply, ask for help from a benefits counselor, job coach, or financial counselor:

• You don't understand how your wages will affect your SSI or SSDI.
• Your paycheck amount changes week-to-week and you can't figure out why.
• You received a letter from Social Security about overpayment or a benefit reduction you didn't expect.
• You've been working for three months and still don't have a budget that works.
• You're not sure whether you should file taxes or how to do it.

Many state vocational rehabilitation agencies offer benefits counseling as part of their services. The Ticket to Work program also provides free benefits counseling through Work Incentives Planning and Assistance (WIPA) projects. Find a WIPA provider at choosework.ssa.gov/findhelp.

FAQ

Do I have to report my job to Social Security if I'm on SSDI?

Yes. You must report within 10 days of starting work, even though SSDI doesn't reduce benefits dollar-for-dollar like SSI. Social Security needs to start tracking your trial work period and SGA months.

What if I don't understand my pay stub?

Ask your employer's payroll or HR department. If they can't explain it in a way that makes sense, bring the stub to your job coach, benefits counselor, or a VITA tax preparer. Don't assume it's correct without verification.

Can I lose my Medicaid if I start working?

It depends on your state and how much you earn. Many states have Medicaid Buy-In programs that let you keep coverage even if your income rises above traditional Medicaid limits. Ask your caseworker or a WIPA counselor about your state's rules before you start work.

What happens if I get paid cash and don't report it?

Cash wages are still wages. Social Security expects you to report them, and the IRS expects you to claim them as income. Unreported cash income can result in overpayment demands from SSA and penalties from the IRS. If you're working for cash, insist on getting paid by check or ask your employer to report your wages properly.

How much should I save before I start spending on wants?

Aim for $200-$300 in savings before committing to discretionary expenses. That buffer covers one light-earning month or an unexpected cost like a car repair or medical copay.

Do I need a separate bank account for work income?

Not required, but helpful if you're on SSI and need to track how much of your balance is from wages versus benefits. Some people open a second checking account just for paychecks to keep the math simple when reporting assets to SSI.

Financial literacy isn't about perfection. It's about knowing what the numbers mean, when to ask questions, and how to set up a system that prevents avoidable mistakes. Open the envelope, read the stub, and ask about anything that doesn't make sense. That's competence, and it's enough.
