You generally need to make quarterly estimated tax payments if you expect to owe $1,000 or more in taxes when you file your return, and you haven’t paid at least 90% of the current year’s tax liability or 100% of last year’s tax liability (110% if your prior-year AGI exceeded $150,000).
This typically applies to self-employed individuals, business owners, freelancers, investors, and anyone with income that doesn’t have tax withheld.
Quarterly estimated tax payments are due on January 15, April 15, June 15, and September 15. If a due date falls on a weekend or holiday, the payment is due the next business day. These dates correspond to the four quarters of the tax year, though the quarters are not equal in length.
Estimate your adjusted gross income, taxable income, taxes, deductions, and credits for the year. Then divide your expected annual tax liability by four, or use the safe harbor rule of paying 100% of last year’s tax (110% if AGI exceeded $150,000).

Yes, if your income or tax situation changes during the year. If your income increases, you may need to increase your payments to avoid penalties; if it decreases, you might be able to reduce them. We recommend reviewing your payments quarterly and adjusting them as needed to stay compliant.
