Social Security disability payments may be includable in taxable income and still not increase the tax you pay. A lump-sum retroactive payment of Social Security Disability Insurance (SSDI) may be includable in taxable income, depending on the amount and your other income and deductions.
While you might have to pay taxes on a small portion of your lump sum payment from Social Security, the IRS does not penalize disability beneficiaries for receiving past-due benefits all in one year.f course, you could owe state taxes on your disability backpay, but most states don't tax Social Security disability benefits. About a dozen states do tax benefits, however, either the same way as the feds or only if you make over a certain amount of adjusted gross income.
