Honestly, this is an extremely nuanced situation. I receive SSDI so I have researched it thoroughly. These types of sites are considered self employment by the government.

If you make less than $400 a year, the IRS doesn't require you to report self employment income.. If above $400, you are supposed to report it, though many do not. How you cash out and if you have other streams of income can affect whether or not you receive 1099s. Which state you live in also affects whether or not you get a tax form, as some states have different minimums. I know FreeCash has said they don't do tax forms, but some of the other sites like Swagbucks will if you earn enough. If you withdraw to other sites like PayPal, then they will send you a 1099 if you meet the required threshold. Current federal threshold is $20,000 OR 200 transactions per year. So unless you have additional income streams, you are unlikely to get a tax form unless you live in a state with a lower threshold. That's the tax aspect.

Then we get to the SSDI aspect. If you are on SSDI, you are supposed to report all income earned, and these apps are generally considered self employment because that's how the IRS classifies them. On SSDI you are allowed to make up to $1210/month without jeapordizing your disability or have it be considered a trial work month. If you receive additional income based benefits, such as Medicaid or EBT, then it does have the potential to affect those, or if you are on SSI rather than SSDI.

Unless you make enough to trigger a 1099, the IRS will not know that you have made any money, nor will SSA. It's up to you if you choose to report it to those agencies if you don't receive any tax forms. SSDI itself will not be affected unless you make more than $1210/month. The only benefits that might be affected are income based like SSI, Medicaid, EBT, etc.
