Frequently Asked Questions

What is Self-Employment (SE) Tax?
Self-employment tax covers Social Security and Medicare for those who work for themselves. It's 15.3% of 92.35% of your net earnings (12.4% for Social Security + 2.9% for Medicare). Source: IRS Pub 334
How much should I save for taxes?
A general rule is 25-30% of your net profit, but it varies by income, state, and filing status. Use the calculator above for a personalized estimate based on your actual numbers.
Why does my W-2 income matter?
The US uses progressive tax brackets. Your side hustle income stacks on top of your W-2 income, so it may be taxed at a higher marginal rate. Adding your W-2 gives you a much more accurate total estimate.
Is this calculator accurate?
It provides estimates based on 2025/2026 rates for planning purposes. Real tax liability depends on credits, other deductions, and individual circumstances. Always consult a CPA for exact filing numbers.
Do I need to pay quarterly taxes?
If you expect to owe $1,000 or more in tax for the year and your withholding doesn't cover it, the IRS requires quarterly estimated payments. Use our Quarterly Tax Calculator to figure out how much to pay.
