Hi. I'd like to clarify an important detail about the exact amount to pay for Quarterly Estimated Tax Payments for Capital Gains.
Lets say I have $40,000 of long-term capital gains in Q1 2021, and my federal tax due is exactly $6,000 (i.e. 15% of $40,000).
do i need to pay IRS all $6,000 by April 15th? or can i pay only $1,500 by April 15th, and then $1,500 in each of the 3 remaining Quarterly Estimated Tax Payment dates?
Also, lets also say I am a CA resident. so, there is another $4,0000 (i.e. 10%) in CA-state tax. do i need to pay CA FTB all $4,000 by April 15th or i can pay only $1,200 (30%) now, and the rest according to remaining Quarterly Estimated Tax Payment requirements stated in https://www.ftb.ca.gov/pay/estimated-tax-payments.html
Please advise! Thanks!
