Frequently asked questions
- When are quarterly estimated taxes due?
- In the US, estimated taxes are generally due in four installments (around April, June, September, and the following January). Check your authority's current calendar, as exact dates shift with weekends and holidays.
- What self-employment tax rate should I enter?
- Below the Social Security wage base, the US combined SE tax is about 14.13% of net income (15.3% applied to 92.35% of earnings). Above the wage base only the Medicare portion continues, so the effective rate falls.
- How do I avoid an underpayment penalty?
- Many jurisdictions offer a safe harbor — paying a set percentage of last year's tax (often 100% or 110%) — that avoids penalties even if you owe more. Use that target if your income is hard to predict.
