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).
