Safe Harbor
Pay 100% of last year's tax (110% if AGI was over $150k) to avoid penalties. If this is your first year, estimate conservatively.
Using IRS Direct Pay (irs.gov)
Go to irs.gov/payments — no registration required. Instant confirmation.
Three things to do right now
- 01Put all four dates in your calendar. April 15, June 15, September 15, January 15. Set a reminder two weeks before each one. Missing a deadline because you forgot is the most avoidable mistake here.
- 02Open a dedicated tax savings account. Move 25–30% of every payment you receive into a savings account you don’t touch. Label it “taxes.” When payment day arrives, the money is already there.
- 03Make your next payment at IRS.gov/payments. IRS Direct Pay is free, takes about five minutes, and gives you an instant confirmation number. No account setup required. If you’re in California, also pay at ftb.ca.gov/pay.
