Just making an example: if I make 4th quarter estimated tax payment(for both federal and state) in January 2020.
1) Will 4th quarter federal estimated tax payment be counted in 2019 federal tax return? I think it is true, but would like to confirm.
2) Will 4th quarter state estimated tax payment be counted in 2020 IRS Schedule A or 2019 IRS Schedule A?
3) Will 4th quarter state estimated tax payment be counted in 2019 state tax return?
4) Can I make 4th quarter estimated tax payment (for federal and state) in December 2019? Instead of January 2020.
Thanks.
