Pay estimated tax for tax year 2020 if:
You expect your 2020 tax after all credits and withholding will be $1,000 or more when you file your return and you estimate that your total withheld tax will be less than:
• One hundred percent of the tax shown on your 2019 income tax return that covered all 12 months of the year; or
• Ninety percent of the tax to be shown on your 2020 income tax return; or
• Ninety percent of the tax on your 2020 annualized income.
Even if you expect that your 2020 tax after all credits and withholding will be less than $1,000, you may still make estimated tax payments
