Quarterly Estimated Tax Payment FAQs

Who needs to make quarterly estimated tax payments?

You generally need to make quarterly estimated tax payments if you expect to owe $1,000 or more in taxes when you file your return, and you haven't paid at least 90% of the current year's tax liability or 100% of last year's tax liability (110% if your prior year AGI exceeded $150,000). This typically applies to self-employed individuals, business owners, freelancers, investors, and anyone with income that doesn't have taxes withheld.

When are quarterly estimated tax payments due?

Quarterly estimated tax payments are due on January 15, April 15, June 15, and September 15. If the due date falls on a weekend or holiday, the payment is due the next business day. These dates correspond to the four quarters of the tax year, though the quarters are not equal in length.

How do I calculate my quarterly estimated tax payments?

Calculate your quarterly payments by estimating your adjusted gross income, taxable income, taxes, deductions, and credits for the year. Divide your expected annual tax liability by four, or use the safe harbor rule of paying 100% of last year's tax (110% if AGI exceeded $150,000). We recommend working with a tax professional to ensure accurate calculations and avoid penalties.

What happens if I don't make quarterly payments?

If you don't make required quarterly payments, you may face underpayment penalties from the CRA, even if you receive a refund when you file your annual return. The penalty is calculated based on the amount underpaid and how long the payment was overdue. The current penalty rate is updated quarterly and is typically around 3-8% annually.

Can I adjust my quarterly payments during the year?

Yes, you can adjust your quarterly payments if your income or tax situation changes during the year. If your income increases, you may need to increase your payments to avoid penalties. If your income decreases, you might be able to reduce your payments. We recommend reviewing your payments quarterly and making adjustments as needed to stay compliant.
