If you work for yourself, self-employment tax is usually the piece that catches people off guard. It covers the Social Security and Medicare that an employer would normally split with you — but as your own boss, you pay both halves. It applies to 92.35% of your net profit at a combined 15.3% rate, with the Social Security portion capped at the annual wage base.
The good news: you get to deduct half of it against your income, and every legitimate business expense lowers the profit it’s calculated on. When you’re ready for your exact number — and every deduction you’re owed — that’s what we’re here for.
