Quarterly Taxes for Seasonal Gig Workers: Paying Only When You Earn (2026)
Plenty of gig workers earn most of their money in a few busy months — holiday deliveries, summer rideshare, tax-season tutoring. Paying four equal quarterly estimates makes no sense when your income isn't equal. The IRS has a method for that. Size each payment with the quarterly taxes for gig workers calculator.
The default rule assumes even income
Normally the IRS expects 25% of your annual tax on each of the four deadlines: April 15, June 15, September 15 and January 15. If you pay less early in the year, you can owe an underpayment penalty for those quarters even if you catch up later.
The annualized installment method
Form 2210, Schedule AI, lets you calculate each required payment based on the income you actually earned up to that period. If you earned almost nothing January through May, your required April and June payments can be close to zero.
The periods it uses
The method looks at cumulative income for January 1–March 31, January 1–May 31, January 1–August 31 and the full year. Those cutoffs match the April, June, September and January deadlines.
Example: a holiday-heavy delivery driver
Jordan earns $4,000 of gig profit January–August and $16,000 from September to December. With equal payments he'd need about a quarter of his annual tax every deadline. Using annualization, his April, June and September payments are small, and most of his tax is due January 15.
What you need to do
Track profit by month, pay based on what you earned in each period, and attach Form 2210 with Schedule AI when you file. Tax software handles the math if your monthly records are clean.
An easier option if last year was similar
If your income is roughly steady year to year, the safe-harbor rule may be simpler: pay 100% of last year's total tax (110% above $150,000 AGI), split evenly, and you're protected no matter when you earn.
Frequently asked questions
+Do I have to tell the IRS in advance that I'm using annualized payments?
No. You simply pay according to your income and attach Form 2210 with Schedule AI to your return.
+Does this work for state taxes too?
Many states allow a similar annualized method, but rules vary. Check your state's estimated tax form.
+What if I'm a full-time driver with steady income?
Annualizing won't help much. Equal quarterly payments or the safe-harbor rule are simpler.
