If you have or expect to receive a disability pension, it's important to understand how disability benefits are taxed. Most, but not all, disability pensions are taxable.
If you retired early on disability, you must include in income any disability pension you receive under a plan that is paid for by your employer. You report your taxable disability payments as wages on line 7 of Form 1040 or Form 1040A until you reach minimum retirement age. Minimum retirement age generally is the age at which you can first receive a pension or annuity if you are not disabled. If you don't know your plan's minimum retirement age, check the plan documents or ask your employer.
Beginning on the day after you reach minimum retirement age, payments you receive are taxable as a pension or annuity. Report the payments on lines 16a and 16b of Form 1040 or on lines 12a and 12b of Form 1040A. For more information on pensions and annuities, see IRS Publication 575, Pension and Annuity Income.
If you retire on disability, any lump-sum payment you receive for accrued annual leave is a salary payment. The payment is not a disability payment. Include it in your income in the tax year you receive it.
You do not have to pay income tax on certain military and government disability pensions.
