Confirm you actually owe estimates
You must pay estimates if you expect to owe $1,000+ at tax time. You must also pay if the tax taken out of your pay covers less than 90% of this year's tax or 100% of last year's tax. The rule is 110% if your income was over $150,000 last year. Do you have a salary job and a small side job? It can be easier to have more tax taken out on your W-4 instead.

FAQ
Frequently Asked Questions
What happens if I miss a quarterly deadline?
The IRS charges interest if you pay too little. The rate is 7% per year for Q4 2026; the IRS resets the rate each quarter. The rate was 6% for Q2 2026. It changes each quarter. The IRS charges interest on the amount you missed, for the days it was late. It works this out with Form 2210. The IRS does the math on its own. You do not need to file a separate form. One late quarter on a small amount usually costs just a few dollars.
I just started freelancing and have no idea what I'll earn. What do I do?
Use last year's safe harbor if you had a job last year. Or guess from your income in your first few months. Set aside 25–30% of each payment in a separate savings account. Keep it as a safety fund.
Do I have to pay estimates on investment income?
Not usually. You can cover tax on investment income in other ways. You can have more tax taken out on your W-4 or make one big Q4 payment. The IRS treats tax taken out of your pay as if you paid it evenly all year. It does not treat estimates that way. So tax taken out of your pay is more forgiving.
