Your Social Security Disability Benefits may be taxable if: you have other income besides your benefits, or if you spouse earns a lot of money. Now if you file as an individual, and all of your income is between $25,000 and $34,000, 50% of it may be taxed, if it's more than $34,000, then 85% of your SSDI would be taxed. If you are married filing together, 50% of your SSDI may be taxed if you and your spouse's income is between $32,000 and $44,000. Finally if your joint income is more than $44,000, then 85% of your SSDI could be subject to tax. If you think it may be possible then you might want to make sure to set aside some money to cover those taxes.
