Does one have to pay estimated taxes for capital gains? I have a large amount of capital gains for the first quarter of 2021, do I need to pay estimated taxes on them?

If you pay 110% of what you paid in 2021 then you won't receive a penalty.

I had capital gains of around 100,000 dollars total in 2021. What should I pay in my estimated tax payment.

I have requested an extension for filing.

Yes, you should have paid estimated taxes, on your $100,000 capital gains, in the first quarter of 2021. Taxes are pay-as-you-go. This means that you need to pay most of your tax during the year, as you receive income, rather than paying at the end of the year.

Regarding what you should pay in, we can't tell you an amount or percent since the amount is dependent on all your income, deductions, filing status, etc. One way to get a good estimate of how much to pay is to use TurboTax.

You haven't provided enough info to answer that question.

As you appear to know, when you file an extension, you still need to pay the amount of tax due before April 18. Normally, you would be far enough along in your tax prep that TT has calculated a preliminary tax due. You would pay a little bit more than that to be safe.

If you haven't gotten that far, you can use this tool to do an estimate: https://turbotax.intuit.com/tax-tools/calculators/taxcaster/?s=1

The rule is that you must pay your taxes as you go.

To determine whether you need to make quarterly estimates, check if both of the following apply:

• You expect to owe at least $1,000 in tax for the current tax year after subtracting your withholding and refundable credits, and
• You expect your withholding and refundable credits to be less than the smaller of:
  • 90% of the tax to be shown on your current year's tax return, or
  • 100% of the tax shown on your prior year’s tax return. (Your prior year’s tax return must cover all 12 months.)

Q. Does one have to pay estimated taxes for capital gains? I have a large amount of capital gains for the first quarter of 2022, am  I need to pay estimated taxes on them?

A. Simple answer: No, that is not required.  However, you might be subject to an underpayment penalty if you were "short".  Usually, if you are currently withholding federal  tax at a rate equal to last year's tax, there will be no penalty, even if you owe a hugh amount at tax time.  See @MayaD 's reply for details.
