Frequently Asked Questions

When are quarterly taxes due in Georgia?
Federal quarterly deadlines: April 15 (Q1), June 15 (Q2), September 15 (Q3), January 15 (Q4). Georgia follows the same schedule for state estimated payments.
How do I calculate quarterly taxes in Georgia?
Estimate your annual income, subtract deductions, calculate tax, and divide by 4. Or use the safe harbor method: pay 100% of last year's tax (110% if AGI > $150K). Our calculator above does this automatically.
What happens if I miss a quarterly payment in Georgia?
The IRS charges interest on underpayments (currently 8% annual rate). Georgia may impose additional penalties. Even partial payments reduce your penalty.
Can I skip quarterly payments in Georgia?
You can skip if you expect to owe less than $1,000 total, had zero tax liability last year, or your withholding covers 90%+ of this year's tax. Otherwise, skipping triggers penalties.
How do I pay quarterly taxes online in Georgia?
Pay federal taxes via IRS Direct Pay (free), EFTPS, or credit card (fees apply). Pay Georgia taxes through the state Department of Revenue website.
