Who Needs to Pay Quarterly Taxes?
You generally must pay estimated taxes if you expect to owe $1,000 or more in federal tax after subtracting withholding and credits. This commonly applies to self-employed individuals, independent contractors, gig workers, landlords, and retirees with significant investment income. W-2 employees with adequate withholding usually do not need to pay quarterly.
When Are Quarterly Tax Payments Due?
The four deadlines are: April 15 (for Q1: Jan-Mar), June 15 (for Q2: Apr-May), September 15 (for Q3: Jun-Aug), and January 15 of the following year (for Q4: Sep-Dec). Note that the periods are not equal quarters. Missing a deadline triggers an underpayment penalty even if you pay in full when filing your Form 1040.
How Do You Calculate Quarterly Tax Payments?
Use Form 1040-ES to estimate your annual tax liability, then divide by four. Safe harbor rules let you avoid penalties by paying either 100% of last year's tax (110% if AGI exceeds $150,000) or 90% of the current year's tax. Many tax professionals recommend the prior-year safe harbor method for simplicity.
Frequently asked questions
What happens if you miss a quarterly tax payment?
The IRS charges an underpayment penalty calculated as interest on the unpaid amount for each quarter. The penalty applies separately to each missed or underpaid installment. Pay as soon as possible to minimize the interest accruing on the shortfall.
Can you pay quarterly taxes online?
Yes. IRS Direct Pay, EFTPS (Electronic Federal Tax Payment System), and credit/debit card payments are all accepted. Many state tax agencies offer similar online payment portals. EFTPS is free and allows you to schedule payments in advance.
