Social Security counts online sales income the same way it counts any other self-employment income

If you sell items online—through eBay, Etsy, Facebook Marketplace, Amazon, or your own website—Social Security treats that as self-employment income. The amount that matters to SSDI is your net profit, not the total money that passes through your account. Net profit means what you keep after you subtract the cost of goods, shipping, fees, and other business expenses.

Social Security uses your net profit to decide whether you're working above the level that SSDI allows. In 2024, if your net profit from self-employment reaches a certain threshold each month, Social Security may decide you're doing substantial gainful activity—the term they use for work that's too much to combine with SSDI. The threshold changes each year, so you need to check the current amount with Social Security directly or through their website.

The key difference from a regular job is that you report net profit, not gross sales. If you sold $5,000 worth of items but spent $3,000 on inventory and $400 on shipping and fees, your net profit is $1,600. That $1,600 is what Social Security counts toward your income limit.

Key Takeaways

  • Social Security counts only your net profit from online sales, not the total amount of money you receive from buyers.
  • Net profit means the money left after you subtract inventory costs, shipping, platform fees, supplies, and other direct business expenses.
  • You must report all online sales income to Social Security, even if the amount is small or you don't receive a tax form.
  • If your net profit crosses Social Security's monthly threshold for substantial gainful activity, your SSDI payments may stop or reduce.
  • Keeping clear records of all sales, costs, and expenses protects you if Social Security asks questions about your income.

What counts as a business expense you can subtract

Social Security allows you to subtract costs that are directly tied to making the sale. This includes the price you paid for the item you sold, shipping materials and postage you paid, platform fees (like eBay's seller fees or Etsy's listing fees), payment processing fees (like PayPal or Stripe charges), and supplies you buy specifically for the business (boxes, tape, labels, bubble wrap).

You can also subtract costs for a dedicated workspace if you use part of your home only for the business, internet service if it's used only for sales, and tools or equipment you buy to run the business. Keep receipts and records for all of these. Social Security may ask to see them, and having documentation protects you from overpayment notices later.

What you cannot subtract: personal expenses, rent or mortgage on your home (unless you're claiming a home office deduction), utilities that serve your whole household, or costs that aren't directly related to making sales. If you're unsure whether a cost counts, write it down separately and mention it when you report to Social Security.

How to report online sales income to Social Security

You must report all online sales income to Social Security, even if the amount is small. You can report it when you first start selling, or you can wait and report it at your annual review. The sooner you report, the sooner Social Security can tell you whether it affects your SSDI payments.

Contact your local Social Security office by phone, in person, or through your online account at ssa.gov. Tell them you have self-employment income from online sales. They will ask you for your net monthly profit and may ask for documentation—bank statements, sales records, receipts for expenses, or tax returns if you file them.

Social Security also wants to know whether you expect the income to continue, how many hours per week you spend on the business, and whether you're doing the work yourself or paying someone else to help. Answer honestly. If your situation changes—if you stop selling, or if your profit goes up or down—report that change too.

The difference between trial work period and substantial gainful activity

SSDI includes a trial work period that lets you test whether you can work without losing benefits when ready. During the trial work period, you can earn any amount and keep your full SSDI payment. The trial work period lasts nine months (not necessarily consecutive) within a rolling 60-month window.

After your trial work period ends, Social Security looks at whether your net profit reaches the substantial gainful activity threshold. In 2024, that threshold is $1,550 per month for most people receiving SSDI. If your net profit stays below that amount, you keep your full SSDI payment. If it goes above, your benefits reduce or stop.

The threshold changes each year, so check with Social Security for the current amount. Also, if you're blind, the threshold is higher. The trial work period and the substantial gainful activity rules are separate—using your trial work period months doesn't prevent you from working below the threshold later.

When Social Security asks for proof of your income

Social Security may ask for documentation if your reported income seems inconsistent with your account activity, if the amount changes significantly from month to month, or during a routine review. They typically ask for bank statements showing deposits from sales, records of your expenses, screenshots of your online seller account, or copies of tax returns if you file them.

Gather these documents before Social Security asks. Keep a straightforward spreadsheet or notebook with the date of each sale, the amount, the cost of goods sold, and any fees or expenses. This record takes minutes to maintain and hours to reconstruct if Social Security requests it later.

If you don't have documentation for past months, explain that to Social Security and start keeping records now. They understand that many people selling online informally don't keep perfect records. What matters is that you're honest about what you earned and that you make a genuine effort to track it going forward.

How online sales income affects your work incentives

SSDI includes several work incentives designed to let you test work without losing benefits all at once. The trial work period is one. Another is the extended period of may be able to access, which continues your SSDI for 36 months after your trial work period ends, even if your earnings go above the threshold. During those 36 months, you keep your SSDI payment in any month your earnings fall below the threshold again.

There's also a Plan to Achieve Self-Support (PASS), which lets you set aside income and resources for a specific work goal without it counting against your SSDI. If you're planning to grow your online sales business into something larger, a PASS might protect your benefits while you build it. Ask Social Security whether a PASS makes sense for your situation.

These work incentives exist because Social Security recognizes that work is unpredictable, especially self-employment. If your online sales income fluctuates month to month, these programs give you room to keep your benefits while you figure out whether the work is sustainable.

What happens if you don't report online sales income

If Social Security discovers unreported income, they will send you an overpayment notice. This means you received SSDI payments you weren't supposed to get, and Social Security will ask you to repay the money. The amount can be substantial if the unreported income went on for several months.

You have the right to appeal an overpayment notice and explain your situation. You can also ask Social Security to reduce the amount you owe or to let you repay it slowly. But the easiest path is to report the income when it starts, so there's no overpayment in the first place.

Reporting also protects you legally. If you knowingly hide income from Social Security, that's considered fraud, which carries penalties beyond repayment. Reporting honestly, even if it means your benefits reduce, keeps you in the clear.

Frequently Asked Questions

Do I have to report online sales if I only make a few dollars a month?

Yes, you must report all self-employment income to Social Security, regardless of the amount. Even small, irregular sales count. The sooner you report, the sooner Social Security can tell you whether it affects your benefits. Reporting small amounts is much simpler than dealing with an overpayment notice later.

What if I sell items I already own, like used clothes or furniture?

If you're selling personal items you already owned, you generally don't count the sale as income—you're just recovering what you paid for them. But if you're buying items specifically to resell them, that's self-employment income and you must report it. The difference is whether you're running a business or just clearing out your closet.

Does Social Security count money my spouse or family member makes from online sales?

No, Social Security counts only your own income. If someone else in your household sells items online, that's their income and doesn't affect your SSDI. However, if you're receiving Supplemental Security Income (SSI) instead of SSDI, household income rules are different—ask Social Security about your specific situation.

Can I deduct the time I spend on online sales as a work expense?

No, you can't deduct time itself. You can deduct the cost of supplies, materials, fees, and services you buy to run the business. But the hours you work don't reduce your net profit. Social Security counts your net profit the same way whether you spent two hours or twenty hours making the sales.

What if my online sales income changes a lot from month to month?

Report your actual net profit for each month. Social Security understands that self-employment income is uneven. If one month you make $500 and the next month you make $50, report both amounts. Social Security looks at whether you're doing substantial gainful activity, which is based on your actual earnings, not an average.
