When Are Estimated Tax Payments Due?

If you have income without tax withheld — such as self-employment, freelance, rental, or investment income — you generally must pay estimated tax quarterly in four equal installments.

The safest way to avoid the underpayment penalty is to pay 100% of last year's tax (110% if your adjusted gross income exceeded $150,000) or 90% of this year's tax, whichever is smaller. Use IRS Form 1040-ES to calculate.
