Estimated Quarterly Tax Payments: Avoid Penalties
As a small business owner, you're required to pay estimated taxes quarterly if you expect to owe $1,000 or more. Understanding and meeting these deadlines is crucial to avoid penalties.
2026 Quarterly Tax Deadlines
| Quarter | Income Period | Due Date | % of Annual Tax |
|---|---|---|---|
| Q1 2026 | Jan 1 - Mar 31 | April 15, 2026 | 25% |

- Pay that amount each quarter
- No penalty even if you owe more at year-end!
