I lived in the US in 2014, and I got a salary from a company located in Virginia (VA) in 2014 and 2015. I didn't file the VA tax return back then and I want to sort it out now. I did file the federal tax return on time.
I'm not from the US and the tax system puzzles me sometimes. I've found the "estimated tax payments" concept for the first time in the VA form 760. If I got it correctly, they are payments that taxpayers must make in advance when the taxes withheld from the salary are lower than the taxes we have to pay.
I did not make any estimated tax payment in 2014 or 2015. How should I deal with them now?
Since I'm late on filing in the state return for 2014 and 2015, may I just type "0" in the "estimated tax payment" entry and complete the forms normally?
If 2014 return results in me having to pay additional state taxes, does it affect the estimated tax payments?
Do I have to fill in the 2014 and 2015 forms that calculate the "estimated tax payment" for the following year (form 760ES for VA)?
As an aside, do federal taxes affect the amount of state taxes that I have to pay?
