How The IRS Taxes Freelancers

Starting your own business is incredibly rewarding, but the shock of a 'Schedule SE' tax bill during your first April filing can be devastating. When you transition from a W-2 employee to a 1099 contractor, you instantly lose the corporate tax shield that secretly paid for half of your Social Security burden.

The 15.3% Penalty

Normal corporate employees pay 7.65% out of their paychecks to fund FICA (Federal Insurance Contributions Act), and their employer matches the other 7.65% behind closed doors. Because the IRS views self-employed individuals as both the employee and the employer, you are legally forced to pay both halves: a brutal 15.3% tax.

  • 12.4% goes directly to Social Security (capped when earnings exceed $168,600).
  • 2.9% goes directly to Medicare (uncapped, with high-earner penalties).

The Two IRS Silver Linings

To prevent complete small business collapse, the IRS built two distinct 'breaks' directly into Schedule SE:

Break 1: The 92.35% Multiplier

You do NOT pay 15.3% tax on every dollar of profit you make. The IRS assumes you would have deducted your 'employer half' of the tax as a business expense anyway. To skip that tedious paperwork, they simply tax you on 92.35% of your net profit instead of 100%.

Break 2: The Adjustable Gross Income (AGI) Write-Off

When you finally move from Schedule SE to your main Form 1040 to pay standard Federal Income Tax, the IRS allows you to write off exactly 50% of the massive FICA check you just wrote as an 'above-the-line' deduction, lowering your final progressive income tax bracket.
