What Counts as Self-Employment Income?
Net earnings from a trade or business — what is in, what is out (rentals, investments, hobby income), and the partnership and LLC rules
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
Self-employment income is the net earnings from a trade or business you carry on as a sole proprietor, independent contractor, or general partner — profit from regular, continuous activity undertaken for income. It includes Schedule C profit, 1099 contractor income, and a general partner's share of partnership income. It excludes wages, rental income, investment income, and S corporation distributions.

What is the test?
The income must come from a trade or business — an activity carried on with continuity and regularity, with the primary purpose of income or profit — in which you are not an employee. Both halves matter: a one-time sale of a personal item is not a trade or business (no regularity), and wages from a job are not self-employment income (you are an employee). Within a trade or business, the character of the activity, not the label on the payment, controls: a 1099-NEC is evidence of self-employment income but does not create it, and cash received with no form at all is still self-employment income if it came from your business.
What is included?
| Included | Why |
|---|---|
| Net profit from Schedule C (sole proprietorship or single-member LLC) | The core case |
| Income reported on Form 1099-NEC for services performed as a non-employee | Independent contractor earnings |
| Payments through platforms reported on Form 1099-K, to the extent from your business | Gross receipts of the business |
| A general partner's distributive share of partnership ordinary business income, plus guaranteed payments | Partners are self-employed, not employees |
| An LLC member's share of business income where the member participates in management or provides services (the limited-partner exception is narrow for LLCs) | Active members are treated like general partners |
| Fees for serving on a board of directors | A trade or business of being a director |
| Income from a side business alongside a W-2 job | Profits and losses from all businesses are combined on Schedule SE; the US$400 threshold applies to the total |
| Ministers' earnings and certain religious workers (special rules) | Statutory inclusion |
What is excluded?
| Excluded | Why |
|---|---|
| Wages, salaries, tips from employment (Form W-2) | You are an employee; payroll tax already applies |
| S corporation shareholder distributions and pass-through income | Not self-employment income; the shareholder's salary carries payroll tax instead |
| Rental income from real estate (Schedule E) | Excluded unless you are a real estate dealer or provide substantial services (a hotel-like operation) |
| Interest, dividends, capital gains | Investment income, not a trade or business |
| A limited partner's distributive share (other than guaranteed payments for services) | Statutory exclusion — though the IRS and courts have narrowed it for LLC members and "limited partners" who actively participate, and the courts are still divided on the test |
| Hobby income | Not a trade or business (no profit motive); reported as other income with no deductions |
| Gains from selling business property (Form 4797) | Capital or section 1231 gains, not operating income |
| Certain payments: jury duty, most prizes, notary fees (notary public fees are specifically exempt) | Statutory exclusions or not from a trade or business |
The gray areas
Rentals with services: renting rooms is Schedule E; running a bed-and-breakfast with meals and daily cleaning is a business on Schedule C. Short-term rentals sit on the line, decided by the level of services provided. LLC members: a member of a multi-member LLC who works in the business generally has self-employment income on their full share; the "limited partner" exclusion is not available to someone who is a limited partner in name only. Occasional work: a professor paid to give three lectures a year has a trade or business; someone who sells one used car does not. Under US$400: income under the threshold is still taxable as income — it just carries no self-employment tax and needs no Schedule SE.
Worked example
A schoolteacher (W-2) also tutors privately (US$9,000 through a platform, on a 1099-K), owns a duplex (US$14,000 of net rent), holds an S corporation interest in a family business (US$20,000 K-1 income, no salary — a problem of its own), and sold a personal bicycle for US$600. Self-employment income: the US$9,000 of tutoring only. The wages are employment; the rent is Schedule E; the S corporation income is not self-employment income; the bicycle sale is a personal-use asset (no gain, no business). Self-employment tax applies to US$9,000 × 92.35% — with the teacher's W-2 wages counting against the same Social Security wage base.
Frequently asked questions
Is rental income self-employment income?
Generally no — real estate rentals go on Schedule E without self-employment tax. The exceptions are real estate dealers and rentals with substantial services (hotel-like operations), which are businesses on Schedule C.
Are LLC member distributions self-employment income?
For a single-member LLC, the profit is Schedule C income — yes. For a multi-member LLC taxed as a partnership, a member who works in or manages the business generally has self-employment income on their share; the limited-partner exclusion is narrow.
Is a one-time side gig self-employment income?
If it is an isolated transaction with no continuity, it is generally not a trade or business. Repeated or ongoing work for pay, even part-time, is.
Do I owe self-employment tax under $400?
No. Net earnings from self-employment under US$400 for the year carry no self-employment tax and require no Schedule SE. The income itself is still reportable.

Publication 334 states: “If you have earnings subject to SE tax from more than one trade, business, or profession, you must combine the net profit (or loss) from each to determine your total earnings subject to SE tax. A loss from one business generally reduces your profit from another business.” — Internal Revenue Service, Publication 334, Tax Guide for Small Business, https://www.irs.gov/publications/p334
The IRS states: “Generally, your net earnings from self-employment are subject to self-employment tax.
