Who Does the IRS Consider "Self-Employed"?
The IRS uses a broad definition — even a modest side income can trigger self-employment obligations. You are generally self-employed if you operate as any of the following:
Freelancers
Writers, designers, developers, consultants providing services to multiple clients without being on a formal payroll. Clients paying $600 or more will issue you a Form 1099-NEC at year-end.
Independent Contractors
Professionals — doctors, lawyers, accountants, construction subcontractors — hired for specific projects. No employer withholds taxes from your pay; that responsibility falls entirely on you.
Sole Proprietors
If you run an unincorporated business without registering as a corporation or LLC treated as a corporation, you are automatically a sole proprietor. There is no legal separation between you and your business.
Gig Economy Workers
Rideshare drivers, delivery couriers, short-term rental hosts — income from any gig platform is self-employment income. Platforms may report your earnings on a Form 1099-K when you reach certain thresholds.
Regardless of which label applies to your work, the core principle is the same: you are personally responsible for reporting all income and paying the appropriate taxes directly to the IRS — no employer does this for you.
— Mark Anderson, CPA | About MarkDecoding the Self-Employment (SECA) Tax
When you work a traditional W-2 job, your employer pays half of your Social Security and Medicare taxes. When you work for yourself, the IRS requires you to pay both halves under the Self-Employment Contributions Act (SECA). This is separate from your ordinary income tax.
How the 15.3% Rate Breaks Down
Applies only up to the Social Security wage base: $176,100 for 2025 / $184,500 for 2026
No cap — applies to all net self-employment earnings without limit
An extra 0.9% applies to net earnings above $200,000 (single) or $250,000 (married filing jointly).
Sample SE Tax Calculation

From Net Profit to Tax Due: The IRS Process
You cannot simply multiply your gross income by 15.3%. The IRS requires a specific sequence using Schedule C and Schedule SE.
Report Gross Income & Expenses on Schedule C
List every client payment as gross income — this should match your Forms 1099-NEC and 1099-K. Deduct all ordinary and necessary business expenses: advertising, software subscriptions, travel, office supplies, home internet (if working remotely). The result is your net profit.
Apply the 92.35% Multiplier on Schedule SE
Carry your net profit to Schedule SE. Multiply it by 0.9235 to arrive at your official "net earnings from self-employment." This adjustment mimics the treatment of employees, whose employers' payroll contributions are not counted as taxable employee income.
Apply the 15.3% Rate (Subject to SS Wage Base Cap)
Apply 15.3% to your net earnings. The 12.4% Social Security portion only applies up to the annual wage base ($176,100 for 2025; $184,500 for 2026). If your net earnings are under $400, you are generally exempt from SE tax — but still must report the income for federal income tax purposes.
Claim the 50% SE Tax Deduction ("Above-the-Line")
The IRS allows you to deduct exactly half of your computed SE tax from gross income on Schedule 1 of Form 1040. This above-the-line deduction reduces your Adjusted Gross Income (AGI) regardless of whether you itemize — lowering income tax, improving credit eligibility, and reducing phase-out exposure.
Self-Employed Abroad: The FEIE Trap & Totalization Agreements
Why You Still Owe SE Tax After Using the FEIE
The FEIE (Form 2555) is a powerful exclusion — up to $130,000 of foreign earned income in 2025 — that shields qualifying income from US federal income tax. However, the self-employment tax (SECA) operates under a separate section of the tax code. Congress did not extend the FEIE's protection to cover SECA, so self-employed expats face this surprise liability regardless of how long they have lived abroad.
Proper planning — weighing the Foreign Tax Credit (Form 1116) against the FEIE for your specific situation — can dramatically change your overall liability. This is exactly the kind of analysis Mark provides.
Totalization Agreements: Possible Relief for Some Countries
To prevent dual Social Security taxation, the US has signed Totalization Agreements with approximately 30 countries, including the UK, Germany, Australia, Japan, and Canada. If you are self-employed and reside in a country with such an agreement:
- You generally pay Social Security taxes to only one country
- Long-term residents typically pay into the host country's social system
- You must obtain a Certificate of Coverage from the host country's Social Security Administration to prove exemption to the IRS
Note on Southeast Asia: United States do not currently have a Totalization Agreement, making SE tax planning especially critical for self-employed expats living in the region. Contact Mark to discuss your options.
Estimated Taxes & Avoiding Penalties
Because no employer withholds taxes from freelance or contract payments, the IRS requires you to pay taxes as you earn. If you expect to owe $1,000 or more in federal taxes for the year, you must make quarterly estimated payments using Form 1040-ES.
2026 Estimated Tax Deadlines
Income earned Jan 1 – Mar 31
Income earned Apr 1 – May 31
Income earned Jun 1 – Aug 31
Income earned Sep 1 – Dec 31
A practical rule of thumb: set aside 25–30% of every payment received into a dedicated savings account. Failing to make adequate quarterly payments — or underpaying — triggers IRS underpayment penalties and accrued interest by April filing time. Mark can help you calculate accurate quarterly estimates and build a payment schedule that protects you from penalties.

Frequently Asked Questions — Self-Employed Expat Taxes
No — this is the most common and costly misconception for self-employed expats. The Foreign Earned Income Exclusion (FEIE, Form 2555) can reduce your US federal income tax to zero on up to $130,000 of foreign earned income (2025 limit). However, the self-employment tax (SECA) is a separate obligation under a different section of the tax code, and the FEIE provides no protection against it.
Even if you exclude every dollar of income from federal income tax via the FEIE, you still owe the full 15.3% SECA tax on your net self-employment earnings. Proper strategy — comparing FEIE vs. Foreign Tax Credit for your situation — can make a meaningful difference. Contact Mark to review your options.
Form 1099-NEC (Nonemployee Compensation) is issued directly by a business that paid you $600 or more during the tax year as a freelancer or independent contractor. Form 1099-K is issued by third-party payment processors — PayPal, Stripe, Venmo, or gig economy platforms — and reflects the total transaction volume processed through their networks.
Both forms report income you are required to declare. If a client paid you through a platform that also issues a 1099-K, take care not to double-count the income. All income must be reported regardless of whether a form was issued.
Yes, but with an important limitation on the Social Security component. Your W-2 wages and self-employment income are combined to calculate how much income falls below the annual Social Security wage base ($176,100 for 2025; $184,500 for 2026).
If your W-2 wages alone already exceed the cap, you will not owe the 12.4% Social Security portion of SE tax on your freelance income. However, you will still owe the full 2.9% Medicare tax on all net self-employment earnings, regardless of how much you earn from your W-2 position.
Totalization Agreements are bilateral treaties between the US and approximately 30 countries (including the UK, Germany, Australia, Japan, Canada, and others) designed to prevent double taxation of Social Security contributions. If you are self-employed and reside in a country with such an agreement, you will typically only pay social security taxes to one country — either the US or your host country — rather than both.
For long-term self-employed residents operating a business in the host country, you generally pay into the host country's system and are exempt from the US self-employment (SECA) tax. To claim this exemption with the IRS, you must obtain a Certificate of Coverage from the host country's Social Security Administration. Note that Thailand, for instance, does not currently have a Totalization Agreement with the US, making this issue particularly relevant for expats in Southeast Asia.
If you expect to owe $1,000 or more in total federal taxes — combining both income tax and self-employment tax — when you file your annual return, the IRS requires quarterly estimated payments using Form 1040-ES. Failing to make these payments, or underpaying them, results in IRS underpayment penalties and accrued interest.
For the 2026 tax year, payment deadlines fall on April 15, June 15, September 15, and January 15 of the following year. A practical strategy is setting aside 25–30% of every payment you receive into a dedicated account. Mark can calculate your precise quarterly estimates as part of your annual engagement.
Yes, generally. Even if your income is exempt from US federal income tax because you are a bona fide resident of a US territory such as Puerto Rico, Guam, or the US Virgin Islands, you remain subject to the US self-employment tax on net self-employment earnings. You must file Form 1040-SS (or Form 1040-PR for Puerto Rico) to report your net earnings and calculate your SE tax liability directly with the IRS. These situations are highly specialized — a consultation with Mark is strongly recommended.
