I am trying to figure out how much to send in for my quarterly payments for the 2025 tax year. I expect everything to be the same as my 2024 taxes except that I will have $185,000 of long-term capital gains for 2025. I did an experiment with my 2024 file (Turbo Tax desk top file) and TT came up with about $37,000 for federal taxes. But it printed out the four vouchers for quarterly estimated payments with total up to about $41,000. So, the question is which number to go with for my quarterly payments, the $37,000 or $41,000? Why is it different?
