You should pay in quarterly estimated
taxes if you don't have enough withholding taken out to cover the tax on all
your income. You might be able to increase your W2 withholding to account for
the extra income.
You should make estimated tax payments for the
current tax year if both of the following apply:
- 1. You expect to owe at least $1,000 in tax for
the current tax year, after subtracting your withholding and credits.
- 2. You expect your withholding and 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 tax return must cover all 12 months.)
TurboTax (TT) can prepare the payment vouchers. In

If your goal is just to avoid the
underpayment penalty, then paying 100% of the prior year tax liability is the
“safe haven”
