Frequently Asked Questions
Common questions about estimated quarterly taxes.
In general, self-employed people and freelancers who expect to owe a meaningful amount in tax for the year are expected to make quarterly estimated payments. This is because no employer is withholding tax from your income throughout the year.
Federal estimated payments are generally due four times a year, typically in April, June, September, and January of the following year. Exact dates can shift slightly, so check the current deadlines and confirm any state requirements.
Self-employment tax is the 15.3 percent that covers Social Security and Medicare for people who work for themselves. Employees split this with their employer, but as a self-employed worker you pay both halves, which is why this calculator adds it automatically.
Paying enough through the year, either through estimated payments or withholding, helps you avoid penalties. Many people set aside a percentage of each payment they receive. A tax professional can help you choose a safe target for your situation.
