Why Pay Quarterly Taxes?
As a gig worker, you're responsible for paying estimated taxes throughout the year. Unlike W-2 employees who have taxes withheld automatically, self-employed individuals must make quarterly payments to avoid penalties.
The IRS charges penalties if you don't pay at least 90% of your current year tax liability or 100% of your prior year liability (110% if your income exceeds $150,000).

Frequently Asked Questions
Do I have to pay quarterly taxes?
If you expect to owe $1,000 or more in taxes when you file your return, you generally need to make estimated tax payments. This applies to most gig workers since taxes aren't withheld from their earnings.
What is the self-employment tax rate?
The self-employment tax rate is 15.3%, which covers Social Security (12.4%) and Medicare (2.9%). This is in addition to your regular income tax. However, you can deduct half of your SE tax from your income.
What happens if I miss a quarterly payment?
If you miss a payment or pay less than required, you may be subject to an underpayment penalty. The penalty is calculated based on the amount underpaid and how long it remained unpaid.
What is the safe harbor rule?
The safe harbor rule protects you from penalties if you pay either 100% of last year's tax liability (110% if your AGI was over $150,000) or 90% of your current year's tax liability, whichever is less.
