Myth 1: SE Tax Applies to Gross Revenue
Reality: Self-employment tax applies to net SE income — gross revenue minus all legitimate business deductions. A photographer who earns $90,000 in client fees but has $25,000 in legitimate business expenses has $65,000 in net SE income, and pays SE tax on $65,000, not $90,000. This distinction saves thousands annually for freelancers who maximize legitimate deductions.
Myth 2: An LLC Eliminates Self-Employment Tax
Reality: A single-member LLC taxed as a sole proprietor pays exactly the same SE tax as a sole proprietorship — the LLC structure provides liability protection, not tax reduction. Only an S-corp election (which any LLC or corporation can make) creates the opportunity to reduce SE tax through the salary/distribution split. An LLC without an S-corp election does nothing to reduce SE tax.
Myths 3–6 Debunked
Self-employment tax myths 3–6 and their cost
| Myth | Reality | Cost of Believing It |
|---|---|---|
| Myth 3: Quarterly payments are optional if you’ll pay at filing | Optional only if you want to pay 8% annualized underpayment penalty; practically, they’re required | Hundreds to thousands in penalties annually |
| Myth 4: You only owe SE tax if you get a 1099 | You owe SE tax on all SE income regardless of whether a 1099 was issued — you must report cash payments too | Underreporting triggers IRS notices and penalties |
| Myth 5: The SE tax deduction eliminates SE tax | The 50% SE tax deduction reduces your income tax (not SE tax itself) by deducting half of SE tax from gross income | No one eliminates SE tax through this deduction; it only partially offsets |
| Myth 6: You can deduct everything if you call it a business expense | Deductions must be ordinary, necessary, and for a genuine business purpose — personal expenses remain personal | IRS audit; disallowed deductions; potential fraud penalties |
Believing that quarterly payments are optional is the most immediately costly myth — the IRS charges 8% annualized penalty on underpayments. A freelancer with $20,000 in annual SE tax who pays nothing quarterly owes approximately $800–$1,000 in entirely avoidable penalties every year.
