1099 Tax FAQ
Common questions about freelance taxes, estimated payments, and IRS rules.
What is the difference between Self-Employment Tax and Income Tax?
Self-Employment (SE) tax specifically covers your Medicare and Social Security contributions. W-2 employees split this cost with their employer, but as a freelancer, you are responsible for the full 15.3%. Federal Income Tax is calculated separately based on your overall tax bracket. Freelancers must pay both.
When are 1099 quarterly estimated taxes due?
The IRS operates on a "pay-as-you-go" system. Freelancers are expected to pay taxes four times a year. The standard deadlines are typically April 15, June 15, September 15, and January 15 (of the following year). If you expect to owe more than $1,000 in taxes for the year, you must make these quarterly payments.
How do business deductions lower my taxes?
The IRS allows you to deduct "ordinary and necessary" business expenses. This is crucial because deductions lower your Net Business Profit. Since both your SE Tax and your Federal Income Tax are calculated based on your Net Profit (not your Gross Income), tracking deductions like software, internet, and home office space directly reduces your tax bill.
What happens if I don't pay quarterly taxes and wait until April?
If you owe significant taxes and wait until the annual April deadline to pay them in one lump sum, the IRS will likely charge you an Underpayment Penalty. This acts as an interest charge on the money you should have been submitting throughout the year. Use the quarterly breakdown in our calculator to hit your targets and avoid penalties.
