How Part-Time Work Changes Your SSI and Medicare Benefits

Part-time work reduces your SSI check but usually doesn't affect Medicare

If you're receiving Supplemental Security Income (SSI), the Social Security Administration counts most of your earnings against your monthly payment. For every dollar you earn above $65 per month, SSI reduces your benefit by 50 cents. Medicare, on the other hand, continues regardless of how much you work — there's no earnings limit that will cause you to lose coverage.

The key difference is that SSI is a needs-based program (it looks at your income and resources), while Medicare is an earned benefit (it's based on your or your spouse's work history). Understanding which program follows which rule keeps you from losing money you didn't expect to lose.

Key Takeaways

• SSI subtracts 50 cents from your benefit for every dollar you earn above $65 monthly, so a part-time job that pays $500 a month would reduce your SSI by about $217.50.
• Medicare coverage continues no matter how much you earn, and you keep it as long as you remain enrolled and pay any required premiums.
• The first $65 you earn each month is not counted against SSI, and you can also exclude $20 of unearned income monthly.
• You must report all earnings to Social Security within 10 days of the end of the month in which you earned them, or you risk overpayment and having to repay benefits.
• Some work expenses — like transportation to your job or assistive devices you need to work — may reduce the amount of earnings counted against your SSI.

How SSI calculates your earnings and reduces your payment

Social Security uses a specific formula to determine how much of your earnings count. Start with your gross monthly income (before taxes). Subtract the $65 monthly exclusion — this amount is never counted. Then subtract any approved work expenses. The remaining amount is divided by two, and that result is subtracted from your SSI payment.

For example: You earn $500 a month at a part-time job. Subtract $65 (the exclusion), leaving $435. Divide $435 by two, which equals $217.50. Your SSI payment is reduced by $217.50 that month. If your SSI payment was $943 (the federal rate in 2024, though your state may add more), you would receive $725.50 instead.

This calculation happens every single month, so your SSI payment changes based on how much you actually earn that month. A month when you work fewer hours means a smaller reduction. A month when you work more hours means a larger reduction.

Work expenses that reduce the earnings counted against SSI

Social Security allows you to subtract certain work-related costs before calculating the 50-cent reduction. These expenses must be necessary for you to work and must not be reimbursed by anyone else. Common approved expenses include transportation to and from work, uniforms or special clothing required by the job, assistive devices (like a cane or hearing aid you need to work), and attendant care or personal assistance services.

You do not automatically get these deductions — you must report them to Social Security and provide documentation. Keep receipts and records of what you spend. If you use public transportation, save your transit passes or fare cards. If you pay for a ride to work, keep records of the dates and amounts. If you need an assistant to help you work, document their hours and what you pay them.

Work expenses can significantly reduce how much of your earnings count. If you earn $500 but spend $100 on transportation and $50 on required uniforms, only $285 of your earnings would be counted ($500 minus $65 exclusion minus $150 in expenses), reducing your SSI by $142.50 instead of $217.50.

Medicare continues regardless of your work or earnings

If you may have access to for Medicare through SSI or Social Security Disability Insurance (SSDI), your coverage does not stop or reduce based on how much you work. You keep Medicare Part A (hospital insurance) and Part B (medical insurance) as long as you remain enrolled and pay any required premiums.

Part B has a monthly premium that comes out of your Social Security or SSI payment. In 2024, the standard premium is $164.90 per month, though higher earners pay more. If your earnings cause your SSI to drop below a certain level, you may may have access to for help paying your Part B premium through a program called Savings for may have access to Individuals (SQWI) or may have access to Individual (QI). Contact your local Social Security office or Medicare to ask whether you may have access to.

Part D (prescription drug coverage) also continues, and your premium is based on your income from the previous year. If your earnings increase significantly, your Part D premium may increase the following year, but you will not lose the coverage itself.

What happens if you don't report your earnings

Social Security requires you to report all earnings within 10 days of the end of the month in which you earned them. This means if you work in January, you must report by February 10. If you don't report, Social Security will eventually discover the earnings through employer records or tax filings, and you will owe back the SSI payments you received but were not may have access to to.

An overpayment can be substantial. If you earned $500 monthly for six months and didn't report it, you might owe back $1,305 or more. Social Security can recover this money by reducing your future SSI payments, withholding tax refunds, or taking other collection action. It's far simpler to report the earnings when they happen.

You can report earnings by phone, mail, or online through your Social Security account. Ask your local Social Security office which method works best for your situation. Some offices have representatives who specialize in work incentives and can help you understand the reporting process.

Work incentives that protect your benefits while you earn

Social Security offers several programs designed to help people on SSI or SSDI work without immediately losing all their benefits. The most common is the Plan to Achieve Self-Support (PASS), which allows you to set aside income and resources for a specific work goal — like starting a business, getting training, or buying equipment — without those amounts counting against your SSI.

Another option is Impairment Related Work Expenses (IRWE), which lets you deduct costs related to your disability that enable you to work. This is different from general work expenses. For example, if you have a mobility disability and need to pay for specialized transportation that costs more than regular transit, that extra cost might be deductible as an IRWE.

These programs require advance planning and approval from Social Security. You cannot retroactively claim them after you've already earned the money. If you're thinking about starting work, contact your local Social Security office or a work incentives planning specialist (often called a WIPA representative) before you begin. They can help you structure your work and benefits to keep as much money as possible.

Frequently Asked Questions

Will I lose Medicare if I start working?

No. Medicare continues as long as you remain enrolled and pay your premiums. Your work and earnings do not affect your Medicare coverage. However, if your earnings cause your SSI to drop significantly, you may become uninsured for other types of coverage, so plan ahead.

Can I work and still receive my full SSI payment?

Only if you earn $65 or less per month. Above that, your SSI reduces by 50 cents for every dollar earned. If you earn $200 monthly, your SSI drops by about $67.50. The $65 exclusion is the only amount you can earn without any reduction.

What if my job pays me irregularly — some months more, some months less?

Social Security calculates the reduction based on what you actually earn each month, not an average. A month when you earn $300 results in a smaller reduction than a month when you earn $600. Report your actual earnings for each month as they occur.

Do I have to report tips and cash payments?

Yes. Social Security counts all income, including tips, cash, and informal work. You must report the full amount you earned, not just what you reported to the IRS. Failing to report creates an overpayment that you'll have to repay.

Can I use a work incentives planning specialist to help me understand this?

Yes. Work Incentives Planning and Assistance (WIPA) projects operate in every state and offer free, confidential help understanding how work affects your benefits. They can model different earnings scenarios before you start working. Find your local WIPA at askjan.org or call 1-866-968-WIPA (9472).
