Quarterly estimated taxes are pre-payments to the IRS for income not subject to employer withholding, like from self-employment, covering income, Social Security, and Medicare taxes, typically paid using IRS Form 1040-ES by specific deadlines (April 15, June 15, Sept 15, Jan 15) to avoid penalties, often by basing payments on last year's taxes or current year's income via online or mail payments.

Is it worth paying quarterly taxes?

Yes, you should pay quarterly taxes if you expect to owe $1,000 or more in taxes for the year from non-wage income (like self-employment, investments, or other sources) and your withholding isn't enough, to avoid penalties, with payments generally due April 15, June 15, September 15, and January 15 of the following year. This "pay-as-you-go" system ensures you cover taxes on income not subject to employer withholding, helping manage finances and avoid large bills. 

What happens if I miss a quarterly estimated tax payment?

If you miss a quarterly estimated tax payment, the IRS charges a failure-to-pay penalty and interest on the underpayment, starting at 0.5% per month (up to 25%), plus daily compounding interest, even if you're due a refund later, though penalties can be reduced or waived for certain situations like natural disasters or qualifying retirement/disability, and you should pay the missed amount immediately to stop penalties from growing. 

What triggers IRS quarterly tax payments?
