Frequently Asked Questions
Does my state have quarterly estimated tax payments too?
Most states with an income tax require quarterly estimated payments on self-employment income, similar to federal requirements. Thresholds and due dates vary by state — some states use the same due dates as federal, others differ slightly. Generally, if you owe more than $500–$1,000 in state tax for the year, you'll need to make quarterly state payments as well. Check your state's Department of Revenue website for exact thresholds and due dates.
What is the underpayment penalty rate for 2026?
The IRS underpayment penalty rate for 2026 is the federal short-term rate plus 3 percentage points — typically 7–8% annualized on the underpaid amount. The penalty is calculated quarterly and applied proportionally to how long the underpayment existed. To avoid it entirely, meet the safe harbor: pay 90% of this year's tax or 100% (110% if AGI > $150,000) of last year's total tax liability, in equal quarterly installments.
