If you earn more than $400 in self-employment income per year, the IRS generally expects estimated tax payments quarterly, not just at tax time. This can include both self-employment tax and federal income tax. Missing payments can result in penalties and a surprise bill in April.
Self-employment tax is 15.3% before high-income adjustments: 12.4% Social Security plus 2.9% Medicare. It is generally applied to 92.35% of your net self-employment income. This calculator handles that estimate automatically.
Common deductible expenses may include supplies, equipment, software subscriptions, phone or internet used for business, vehicle mileage, home office space, advertising, professional services, and education related to your business. Keep records for everything you deduct.
Simple trackers for taxes, expenses, and take-home pay.
Fast decision tools for pricing, profit, and product planning.
