Estimated Tax Payments - Am I Required To Pay?
Per the IRS Instructions for Form 1040-ES:

Who Must Make Estimated Tax Payments

The estimated tax rules apply to:
  • U.S. citizens and resident aliens;
  • Residents of Puerto Rico, the U.S. Virgin Islands, Guam, the Commonwealth of the Northern Mariana Islands, and American Samoa; and
  • Nonresident aliens (use Form 1040-ES (NR)).
General Rule
In most cases, you must pay estimated tax for 2020 if both of the following apply.
  1. You expect to owe at least $1,000 in tax for 2020, after subtracting your withholding and refundable credits.
  2. You expect your withholding and refundable credits to be less than the smaller of:
    1. 90% of the tax to be shown on your 2020 tax return, or
    2. 100% of the tax shown on your 2019 tax return. Your 2019 tax return must cover all 12 months.

Note. These percentages may be different if you are a farmer, fisherman, or higher income taxpayer. See Special Rules next.

Exception. You don’t have to pay estimated tax for 2020 if you were a U.S. citizen or resident alien for all of 2019 and you had no tax liability for the full 12-month 2019 tax year. You had no tax liability for 2019 if your total tax was zero or you didn’t have to file an income tax return.
