Frequently asked
Questions, answered
When are sole proprietor quarterly estimated tax payments due?
The IRS uses four estimated-tax periods that don't line up evenly with calendar quarters. Federal due dates are generally April 15, June 15, September 15, and January 15 of the following year. If a date falls on a weekend or holiday, it shifts to the next business day. You pay online through IRS Direct Pay or EFTPS. Many states require their own quarterly estimates on separate dates, so check your state alongside the federal schedule.
How do I calculate quarterly taxes when my income is seasonal or unpredictable?
Quarterly estimates must cover both income tax and self-employment tax (Social Security and Medicare on net profit). For uneven income like campgrounds, STRs, or SaaS, the IRS annualized income installment method lets you pay based on what you actually earned each period instead of four equal amounts, reducing penalties in slow quarters. Recalculate after every quarter using year-to-date profit. A bookkeeper or CFO who tracks your books monthly makes this far more accurate than annual guessing.
How can I avoid underpayment penalties on estimated taxes?
The IRS generally waives the underpayment penalty if you pay at least 90% of the current year's tax or 100% of last year's tax through withholding and estimates. That threshold rises to 110% of last year's tax for higher-income filers. The penalty is calculated as interest on the shortfall, so paying even a late estimate reduces it. Setting aside a fixed percentage of every deposit and automating payments are the most reliable ways to stay above the safe-harbor line.
