Business taxes can still apply
The Business Profits Tax and Business Enterprise Tax can apply to businesses above gross income and receipts thresholds that the state adjusts over time. Check the Department of Revenue Administration's current figures as your business grows.
Your federal tax comes first
Wherever you live, self-employed income is subject to federal income tax and self-employment tax. A single filer with $60,000 of net profit and no other income owes about $12,037 in federal tax for 2026, or 20% of profit, before any state or local tax.
Federal estimated payments are due April 15, June 15, and September 15, 2026, and January 15, 2027. Use our 1099 tax calculator to run your own numbers.
