Hello TT community, I'm on Social Security, am 671/2 and didn't file in 2025. Can I still file federal and state?

At end of 2024 I was 661/2. I made a little gig money on the side. Do I need to include that income?

If you file a tax return you have to include all of your income, including "a little gig money."

If "a little gig money" is $400 or more you are required to file a tax return.

You can always file a late tax return, the IRS will always accept it.  There may be some interest and penalties if you owe tax and you file late, but the longer you wait, the more the penalties will be.  

Turbotax is still available for the 2024 tax season, both online and as software you download and install on your own computer.  The online version is "free to start" and you only pay if you need to file.  The download version is pay up front.

You can use this web site to find out if you are required to file.

If your only income is social security, that is tax-free and you don't need to file.  As you add more types of income (pension, small job, self-employment) it becomes more likely that you need to file.  For any combination of wages, pension and social security, check the IRS web site calculator.  But, if you have self-employment, you must file if your net profit from self-employment is more than $400, no matter what other income you have.  If you file a tax return for any reason, you must report all your income, no matter how small any one item might be.

And...to be clear since you mentioned your age more than once....your age has nothing to do with whether you need to file a tax return.   The need to file a tax return is determined by how much income you had and what kind(s) of income you had--no matter whether you are an infant or 100 years old.   If you had "side gig" income of over $400 from self -employment, you are required to file a tax return and pay self-employment tax for Social Security and Medicare, even if you do not owe any other ordinary income tax.
