  3. Click Calculate to see the total to set aside and the quarterly amount.

How the estimate works

Self-employment tax covers Social Security and Medicare and is 15.3 percent, but it applies to 92.35 percent of net income. Half of it is deductible for income tax. On top of that you owe income tax at your own rate. The total is split into four quarterly payments.

SE tax = net x 0.9235 x 0.153 income tax = (net - half of SE tax) x your rate quarterly = (SE tax + income tax) / 4

A real example

A freelancer with 80,000 dollars of net income owes self-employment tax plus income tax. Setting aside the quarterly figure into a separate account each quarter avoids a painful bill at year end and possible underpayment penalties.
