Four Steps to Safe Harbor
Determine Prior Year Liability
Apply AGI Percentage Threshold
Compare Current Year Projections
Divide Into Equal Vouchers
Remit one-fourth of your target safe harbor amount across April 15, June 15, September 15, and January 15 payment deadlines.
Locate Line 24 on your previous year's Form 1040. This baseline dollar amount anchors your underpayment penalty exemption threshold.
If prior year Adjusted Gross Income was under $150,000, target 100% of that total tax. If over $150,000 ($75,000 MFS), target 110%.
Alternatively calculate 90% of your current tax year total liability. Pay whichever benchmark yields the lower required quarterly sum.
