For the first time, I have enough deductions to itemize, but I think I deducted too much, and now I have to fix it.
I used TaxAct to do my federal return, and it listed all the tax that was withheld by CA on Sch A. However, after I did my state taxes, I got a refund. So I’m pretty sure that means I need to go back to the Federal return and amend it to show that I paid less in state income taxes.
The reason I’m confused by this is that TaxAct showed numbers for both federal refund and state refund. If they knew that I’d get a state refund, why did they include the full amount withheld in my federal deductions? Maybe because I didn’t actually do my state return with them? If so, I now understand why they’ll let you file your federal return for free and only pay for the state return. You have to do the state return with them or they do the federal return incorrectly.
In the past, I’ve always done my federal return first, then done my state return. But now it sounds like I probably have to do them simultaneously, since you can’t really finalize either one until some work has been done on the other. Is this what other people do?
Finally: Since I’m going to get more money back from the Feds than I should, will I have to pay penalties/interest? The difference is only going to be about $200. If I file my amended return with a check before April 15 I should be fine, right?
