| To supplement the comment I left regarding TurboTax (http://news.ycombinator.com/item?id=1783200), I thought I'd lay out exactly how and when I interact with the IRS. About 50% of my income comes from freelancing; the other 50% from a full-time job. January 15: Send the IRS a check for 28% of the gross freelance income you made between September 1 and December 31 of the previous year along with a 1040-ES (http://www.irs.gov/pub/irs-pdf/f1040es.pdf) Also send an estimated payment to your state of about 5-7%, based on your state's income tax bracket for your income. (My state, Minnesota, has easy online payments, so there's no paperwork required.) Between March 1 and April 15: Do your taxes. Use TurboTax; it will simplify your life. Take appropriate deductions for everything that TurboTax asks, but make sure to have documentation. April 15: Repeat what you did on January 15, but for income received between January 1 and March 31. June 15: Repeat January's step again, but for income from between April 1 and May 31. September 15: Repeat January again, but for income from between June 1 and August 31. Note that you only really need to make estimated payments if you expect to owe more than $1,000 on tax day if you were to not make estimated payments. If you owe more than $1,000 when tax day comes, you may be charged a penalty if you didn't make estimated payments. (I'm not an accountant, so your mileage may vary.) |
