Doing VA taxes and I am asked for Form 760C, line 3, prior year tax liability. Is that info on the VA tax form or federal form. I can't even locate last years VA tax form. :( Sorry to be so think but ai am dealing with a husband who is terminally ill and I am not firing on all six cylinders. Thank you for your patience.
Yes, form 760C is the Virginia form that calculates underpayment of estimated taxes.
Line 3 on form 760C on your 2023 return is "2022 Income Tax Liability After Spouse Tax Adjustment and Tax Credits". This is used to help calculate if you even owe a penalty for underpayment.
You can get a copy of your 2023 return from the state, but it will be by mail, and may not come for up to 10 days (their estimate). To get a copy, please see this Virginia page.
Note the state of Virginia says this:
Filing Extensions
Can't file by the deadline? Virginia allows an automatic 6-month extension to file your return (Nov. 1 for most filers). No application is required. You still need to pay any taxes owed on time to avoid additional penalties and interest. Make an extension payment.
Please the page above if you have questions on this. Yes, you can file your federal return (1040) now if you want, and your state return later.
