There is no age limit for filing taxes. But, there is an income limit.
Q. Does social security count as income when determining is you have enough income to have to file a tax return?
A. It's complicated but the simple answer is: No, for most people.
Social security only becomes taxable when added to sufficient other income.
Social security (including SSDI) becomes taxable when your income, including 1/2 your social security, reaches:
Married Filing Jointly(MFJ): $32,000
Single or head of household: $25,000
Married Filing Separately and lived with your spouse at any time during the tax year: $0
How much is "sufficient other income"? The simple answer is $14,600 (a single person's filing requirement). But the answer varies dependent on marital status, filing status, age, the amount of your Social security, and whether you are claimed as a dependent by someone else.
