Quarterly Tax Calculator: Calculate Estimated Tax Payments

A comprehensive guide to quarterly tax calculations

Quarterly estimated tax payments are required when you expect to owe $1,000 or more in taxes for the year and your withholding doesn't cover your tax liability. This applies to self-employed individuals, freelancers, investors, and others with significant non-wage income. Payments are due April 15, June 15, September 15, and January 15.

A Quarterly Tax Calculator estimates your required quarterly payments based on your expected annual income, deductions, and credits. This tool is essential for self-employed individuals and others with non-wage income to avoid underpayment penalties.

Making accurate quarterly estimated payments helps avoid penalties and ensures you don't face a large tax bill at year-end.

Frequently Asked Questions

Who must make quarterly estimated tax payments?

You must make estimated payments if you expect to owe $1,000+ in taxes after subtracting withholding and credits, and your withholding is less than 90% of your current year tax liability or 100% of last year's tax (110% if AGI over $150,000).

When are quarterly estimated taxes due?

Estimated tax payments are due April 15 (Q1), June 15 (Q2), September 15 (Q3), and January 15 of the following year (Q4). If the due date falls on a weekend or holiday, the deadline is the next business day.

How do I calculate quarterly estimated taxes?

Estimate your total annual income, deductions, and credits. Calculate your expected tax liability and divide by 4. Alternatively, use the annualized income method if your income varies throughout the year.

What if I underpay my estimated taxes?

Underpayment can result in a penalty, typically calculated based on the amount underpaid and how long it was underpaid. The penalty rate is set quarterly by the IRS and is generally around 3-8% annually.
