First time quarterly taxes for self employed client who started freelancing this January. I cleaned up his books in QBO so I thought he could file through TurboTax. However, he has already filed 2025 personal taxes through AARP volunteers and has filed with them the last two years. He does not have a history in TurboTax.
Should he file his estimated quarterly taxes here through FreeTaxUSA and how?
I clean up the books. I am not a tax professional in the least. What should I advise him to do?
