Guides
Estimated taxes
If no one withholds tax from your pay, you pay it yourself during the year. These guides walk through the IRS rules and the state rules that differ, starting with California.
What this section covers
- Whether you need to make estimated payments
- How to calculate each payment, with a worked example
- IRS due dates, and state schedules that differ, such as California’s 30/40/0/30
- Paying online through IRS Direct Pay and state payment sites
- What to do if you missed a payment
New guides are added every week. Each one shows the date it was last checked against official sources.
