Self-Employment Tax Deduction: How 1099 Earners Get Back Half

Jeremy Knight, CPA • November 3, 2026

Quick answer: If you earn $400 or more in net self-employment income, you pay self-employment tax of 15.3% for Social Security and Medicare, the share an employer would normally split with you. You get to deduct half of that tax from your income. Every legitimate business expense you claim also lowers your profit, which lowers both your income tax and your self-employment tax.

Self-employment tax at a glance

  • Who pays it: Self-employed people with $400+ in net earnings
  • Rate and deduction: 15.3% (12.4% Social Security up to the annual wage cap + 2.9% Medicare); half is deductible
  • Records to keep: All income records, business expense totals, W-2s, estimated tax payments

What affects your self-employment tax

  • Your gross business income from 1099-NEC, 1099-K, cash, checks and app payments
  • Your total business expenses (every legitimate deduction lowers it)
  • Any W-2 wages you also earned, which count toward the Social Security wage cap
  • Whether you made quarterly estimated payments

What this deduction is not

  • It isn't a business expense; it's an adjustment that reduces your income on your 1040
  • It doesn't reduce the self-employment tax itself; it reduces your income tax
  • It doesn't apply to W-2 employees, whose employer pays half of these taxes

How to gather your self-employment records

  1. Collect every 1099-NEC and 1099-K you receive in January.
  2. Pull your own income records (invoices, deposits, app statements); not every payer sends a 1099.
  3. Total your business expenses by category.
  4. Gather any W-2s from jobs you also worked.
  5. List every estimated tax payment with the date and amount.

How to organize and bring your data to Hub City Tax Pros

  1. Put all income documents in one folder and write your own income total on top.
  2. Put expense totals by category on one page.
  3. Add your W-2s and estimated payment list.
  4. Bring everything to our Lubbock office. We'll also set up next year's quarterly estimates so April isn't a surprise.

Common mistakes

  • Reporting only income that came with a 1099
  • Skipping estimated payments and owing penalties
  • Missing expenses that would have lowered both taxes
