Simple answer: $7100 (14.1% x $7100 = 1000).
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.)

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