About to start being an Independent Contractor - Any advice on estimating taxes?
I agree with your strategy of using a conservative estimate to overpay taxes and get a refund next year. As a self-employed individual you are responsible for paying self-employment tax (which means paying Social Security and Medicare tax for yourself as both: employee and an employer.) Current Social Security Rate is 6.2% and Medicare is 1.45%, so your Self-employment tax is 15.3% (7.65%X2) Assuming you are single, your effective tax rate will be over 10% (portion of your income under $ 9,075), but less than 15% ($9,075-$36,900), so to adopt a conservative approach, let's use the 15% number.  Given Self-employment and Federal Income tax rate estimates, very conservative approach, your estimated tax can be 30% (Self-employment tax plus income tax) Should you expect much higher compensation, you might move to the 25% tax bracket and adjust this amount to 40%.
