Self-Employment Tax Deductions for U.S. Expats: What Can You Write Off?

U.S. expats can deduct ordinary and necessary business expenses—including software, professional fees, equipment, marketing and qualifying home-office costs—from their self-employment income. These deductions can reduce both income tax and self-employment tax, while other tax breaks only affect income tax.

The distinction is easy to miss. At Bright!Tax, we regularly see freelancers abroad claim the Foreign Earned Income Exclusion and assume the rest of the tax calculation will take care of itself. It won’t: the FEIE does not reduce self-employment tax, and where you claim a deduction matters almost as much as what you claim.

What is self-employment tax?

Self-employment tax covers Social Security and Medicare taxes for people who work for themselves. Employees normally split these taxes with an employer; self-employed people pay both portions.

The standard self-employment tax rate is 15.3%:

Part of self-employment tax	Rate	2026 limit
Social Security	12.4%	Applies up to the $184,500 wage base
Medicare	2.9%	No wage-base limit
Additional Medicare Tax	0.9%	Can apply above the relevant income threshold

Self-employment tax is separate from federal income tax, so the same business income can affect both calculations.

Tax	What it is based on	What reduces it
Federal income tax	Taxable income after applicable adjustments and deductions	Business expenses, personal deductions, exclusions and credits
Self-employment tax	Net earnings from self-employment	Business expenses and any applicable totalization agreement
Additional Medicare Tax	Combined wages, compensation and self-employment income above the filing-status threshold	Subject to its own calculation

Self-employment tax can apply if you work as a:

• Freelancer
• Consultant
• Independent contractor
• Sole proprietor
• Small-business owner
• Partner receiving self-employment income from a partnership

If you run your business through an S corporation or another entity, the calculation can work differently.

Under the regular method, you begin with your net business profit—business income minus deductible expenses—and generally multiply it by 92.35% to determine your net earnings from self-employment. Schedule SE then applies the relevant Social Security and Medicare rates.

For example, Ana is a freelance designer in Portugal who earns $80,000 and has $15,000 in qualifying business expenses. Her Schedule C net profit is $65,000. Before applying the self-employment tax rates, she would generally multiply that figure by 92.35%, producing net earnings of approximately $60,028.

Ana’s calculation	Amount
Gross business income	$80,000
Deductible business expenses	−$15,000
Schedule C net profit	$65,000
Net earnings at 92.35%	Approximately $60,028

That is why deductions matter. Software, supplies, insurance, professional fees, travel and other legitimate costs reduce net profit before self-employment tax is calculated.

Other tax breaks—such as the self-employed health insurance deduction—can still lower income tax without reducing Schedule C profit or self-employment tax.

Self-employment tax is ordinarily calculated on Schedule SE and reported with Form 1040.

Do U.S. expats have to pay self-employment tax?

In many cases, yes. U.S. citizens and resident aliens are generally subject to the same self-employment tax rules whether they work inside or outside the United States.

Living abroad does not remove the obligation, and claiming the Foreign Earned Income Exclusion does not reduce self-employment tax.

If this applies to you	Why it matters
You work for yourself abroad	Your net earnings can remain subject to U.S. self-employment tax
You claim the FEIE	It can reduce income tax but not self-employment tax
You pay into a foreign social security system	A totalization agreement can determine which country’s system applies
No totalization agreement applies	You can owe U.S. self-employment tax even while paying taxes abroad
You operate through a company	Your entity type can change how the income is reported and taxed

Malik’s situation shows why the FEIE and self-employment tax must be considered separately. He runs a consulting business from Japan and qualifies to exclude his foreign earned income. That exclusion may reduce his federal income tax, but it does not remove his Schedule SE liability. Japan does have a totalization agreement with the United States, however, so we would next establish which country’s social security system covers his work.

At Bright!Tax, this is one of the first questions we ask our self-employed clients: not just whether they qualify for the FEIE, but whether a totalization agreement changes the Social Security calculation.

How do self-employment tax deductions work?

The phrase “self-employment tax deductions” can refer to several different tax breaks. They do not all affect your return in the same way.

The clearest division is between expenses that reduce business profit and deductions or credits applied later on the return.

Tax break	Reduces business profit?	Reduces self-employment tax?	Can reduce income tax?
Ordinary business expenses	Yes	Yes	Yes
Deduction for employer-equivalent portion of self-employment tax	No	No	Yes
Self-employed health insurance deduction	No	No	Yes
Eligible retirement contributions	No	No	Yes
Qualified business income deduction	No	No	Yes
Standard or itemized deduction	No	No	Yes
Personal tax credits	No	No	Yes—by reducing the tax itself

Deductions that reduce business profit

Ordinary and necessary business expenses are generally claimed against business income on Schedule C if you operate as a sole proprietor or qualifying single-member LLC.

Common examples include:

• Software and subscriptions
• Office supplies
• Contractor payments
• Business insurance
• Legal and professional fees
• Qualifying home-office expenses
• Car and travel expenses
• Marketing and advertising
• Depreciation
• Eligible startup costs

These expenses reduce Schedule C profit, which can reduce both income tax and self-employment tax.

Deductions that reduce income tax but not self-employment tax

Other tax breaks are applied after business profit has been calculated. They can still save you money, but they do not reduce your net earnings from self-employment.

These include:

• Deduction for the employer-equivalent portion of self-employment tax: This reduces adjusted gross income; it does not reduce the self-employment tax itself.
• Retirement contributions: Eligible contributions to plans such as a SEP IRA or solo 401(k) can reduce taxable income.
• Self-employed health insurance deduction: Qualifying premiums paid for you, your spouse and eligible dependents can reduce income tax.
• Qualified business income deduction: Eligible taxpayers can deduct up to 20% of qualified business income, subject to the applicable limits.
• Standard or itemized deduction: Personal deductions reduce taxable income after business profit has been calculated.
• Tax credits: Credits such as the Child Tax Credit reduce the final tax bill rather than business profit.

What business expenses can self-employed expats deduct?

Self-employed expats can generally deduct ordinary and necessary expenses connected with running their businesses. Paying an expense abroad or in a foreign currency does not prevent it from qualifying, but U.S. tax rules still determine how it is treated.

1. Home-office expenses

If you work from home, you may be able to deduct the cost of a qualifying workspace.

The space must ordinarily be used exclusively and regularly for business and meet one of the IRS’s qualifying-use tests. Limited exceptions apply to certain daycare and inventory-storage uses.

Under the actual-expense method, eligible costs can include the business portion of:

• Rent
• Mortgage interest
• Property taxes
• Homeowners’ or renters’ insurance
• Utilities
• Repairs and maintenance
• Depreciation for an owned home
• Internet costs, where properly allocated

Mortgage principal is not deductible.

Suppose Sophie uses a 120-square-foot room in her 1,200-square-foot apartment in France exclusively as her translation office. The room occupies 10% of the apartment, so she could potentially allocate 10% of qualifying costs such as rent and utilities to the business.

There are two ways to calculate the deduction:

Method	How it works
Actual-expense method	Allocates qualifying costs based on business use
Simplified method	Uses $5 per qualifying square foot, up to 300 square feet

Under the simplified method, Sophie’s 120-square-foot office would produce a $600 deduction.

Local tax treatment does not determine whether the space qualifies on a U.S. return. An office in London, Lisbon, Bangkok or Berlin must still satisfy the U.S. home-office rules.

2. Equipment, supplies and depreciation

Business equipment and supplies can be deductible when they are used for your work.

Examples include:

• Laptop
• Monitor
• Printer
• Desk and office chair
• Camera or microphone
• Business phone
• Specialist tools or equipment
• Consumable office supplies

Smaller purchases may be deducted in the year they are bought. Larger assets can require depreciation, which spreads the deduction over several years.

The de minimis safe harbor can allow taxpayers without an applicable financial statement to deduct qualifying property costing $2,500 or less per item or invoice rather than depreciating it. Different limits apply to businesses with an applicable financial statement.

If you buy equipment abroad, keep the original receipt and a record of the U.S. dollar conversion used on your return.

3. Software, subscriptions and online tools

Digital tools used to run your business can qualify as ordinary business expenses.

These might include:

• Accounting software
• Project-management tools
• Design or editing software
• Website hosting
• Email marketing services
• Cloud storage
• Paid research tools
• Professional databases
• Cybersecurity services

When you pay in pounds, euros, pesos or another currency, keep the original invoice and document the U.S. dollar amount reported.

4. Professional fees, legal advice and tax help

Professional fees are deductible to the extent that they relate to your business.

Qualifying costs can include:

• Business bookkeeping and accounting
• The business portion of tax-preparation fees
• Business legal advice
• Contract reviews
• Compliance support
• Business consulting

Personal tax-preparation costs do not become Schedule C expenses simply because you are self-employed. If one invoice covers both your business accounts and personal return, allocate the business portion.

This comes up often with our clients at Bright!Tax. A freelancer might pay one accountant to prepare local business accounts, another to prepare a U.S. return and a lawyer to review a client contract. The business-related portions can qualify, but they need to be separated from personal advice and compliance costs.

5. Business insurance and liability insurance

Premiums for insurance connected with your business can be deductible.

Examples include:

• Professional liability insurance
• General liability insurance
• Cybersecurity insurance
• Equipment coverage
• Industry-specific business policies

Keep the policy documents and payment records with your other business-expense evidence.

6. Startup costs and registration fees

Some costs incurred before a business begins operating can qualify as startup or organizational expenses.

These can include:

• Market research
• Initial advertising
• Website development
• Professional fees
• Business registration
• Certain formation costs
• Pre-opening travel
• Staff training

Startup and organizational costs have separate rules. Some can be deducted when the business begins, while the remaining amount may need to be amortized over 180 months.

Registering a business abroad does not determine its U.S. classification. Before deducting formation costs, establish how the foreign entity is treated for U.S. tax purposes.

7. Marketing and advertising

Ordinary expenses incurred to promote your business can qualify, including:

• Website costs
• Digital or print advertising
• SEO services
• Branding
• Graphic design
• Copywriting
• Sponsored placements
• Email marketing
• Photography
• Social media tools

The question is whether the expense genuinely supports the business rather than a personal profile or hobby.

8. Contractor and freelancer payments

Payments to people who help run or deliver your business can reduce net profit.

This may include payments to:

• Virtual assistants
• Designers
• Developers
• Writers and editors
• Bookkeepers
• Other subcontractors

Keep invoices, contracts and payment records. Payments to U.S. contractors can also create Form 1099 reporting obligations, depending on the recipient, payment method and amount.

9. Bank fees and payment-processing costs

Banking costs can add up quickly when clients, accounts and currencies span several countries.

Deductible business costs can include:

• Card-processing fees
• PayPal, Stripe or Wise business fees
• Wire-transfer charges
• Business bank-account fees
• Foreign-transaction fees
• Currency-conversion charges

If an €800 client payment arrives as €770 after processing and conversion fees, keep both the gross invoice and the fee record. Reporting only the net deposit can make income and expenses harder to reconcile.

10. Car expenses and business travel

You can deduct qualifying car and travel expenses incurred for business.

For vehicle use, you ordinarily choose between:

• The actual-expense method, allocating qualifying vehicle costs based on business use
• The standard mileage method, applying the relevant IRS rate to qualifying business miles

The 2026 business mileage rates are:

Travel date	Rate
January 1–June 30, 2026	72.5 cents per mile
July 1–December 31, 2026	76 cents per mile

A single annual mileage total is therefore not enough for 2026. You need to separate miles driven during the first and second halves of the year.

Other potentially deductible travel costs include:

• Parking and tolls
• Public transport
• Flights for qualifying business trips
• Hotels
• Ground transportation
• The business portion of mixed-purpose travel

Diego’s trip from Madrid to New York included a three-day industry conference followed by four personal days. The airfare and other costs cannot simply be labelled “business travel” because a conference appears somewhere in the itinerary. We would examine the trip’s primary purpose and allocate expenses under the applicable international-travel rules.

Keep itineraries, receipts and notes showing the business purpose of each trip.

11. Business meals

Business meals can qualify when:

• You or an employee is present
• The meal is not lavish or extravagant
• The food or drinks are provided to you or a business associate
• The expense has a genuine business connection
• You keep adequate records

The deduction is generally limited to 50% of the qualifying cost.

Record:

• Who attended
• The date and location
• The amount paid
• The business purpose
• The relationship between the meal and your business

A receipt proves that you bought lunch. It does not prove that lunch was a business expense.

Which tax breaks help without reducing self-employment tax?

Several valuable tax breaks sit outside Schedule C and therefore do not reduce self-employment tax.

Deduction for the employer-equivalent portion of self-employment tax

Self-employed taxpayers generally pay both portions of Social Security and Medicare tax. You can deduct the employer-equivalent portion when calculating adjusted gross income.

If your calculated self-employment tax is $6,000, the related income-tax deduction will commonly be approximately $3,000. You still owe the full $6,000 in self-employment tax; the deduction reduces income tax elsewhere on the return.

Retirement-plan contributions

Eligible contributions to a SEP IRA, solo 401(k) or traditional IRA can reduce taxable income.

The contribution limits and calculations depend on the type of account, your net earnings and your participation in other retirement plans. These contributions do not ordinarily reduce Schedule C profit.

Qualified business income deduction

The qualified business income deduction allows some sole proprietors and owners of pass-through businesses to deduct up to 20% of qualified business income.

The calculation can depend on:

• Taxable income
• Business type
• W-2 wages
• Qualified property
• Other limitations and adjustments

Eligible taxpayers ordinarily use Form 8995 or Form 8995-A. The deduction can reduce income tax but does not directly reduce self-employment tax.

Tax credits and dependents

Personal credits—including the Child Tax Credit and Credit for Other Dependents—can reduce your final tax bill.

They do not reduce Schedule C profit or net earnings from self-employment.

Expat-specific issues that affect self-employment tax deductions

Running a business abroad adds several questions that a domestic-only deduction list will miss.

The FEIE does not reduce self-employment tax

The Foreign Earned Income Exclusion can exclude up to $132,900 of qualifying foreign earned income for 2026, but the excluded income remains part of the self-employment tax calculation.

Tax calculation	Does the FEIE help?
Federal income tax	Yes
Self-employment tax	No
Social security tax under an applicable totalization agreement	The agreement—not the FEIE—determines coverage

Business deductions still matter because they reduce net profit before both the FEIE and self-employment tax calculations.

Totalization agreements can prevent double Social Security taxation

The United States has agreements with certain countries to coordinate Social Security coverage. These totalization agreements determine which country’s system covers a worker and can prevent contributions being charged by both countries on the same earnings.

An agreement can determine:

• Whether you pay into the U.S. or foreign system
• Whether U.S. self-employment tax applies
• Which country issues your benefits
• Whether you need a certificate of coverage

Consider Leah, a U.S. citizen who lives and works for herself in France. The U.S.–France agreement can assign her self-employment coverage to the French system. A certificate of coverage provides evidence that the same income is exempt from U.S. self-employment tax.

The outcome depends on the specific agreement; there is no universal rule for every country. If no agreement applies, a U.S. citizen or resident can owe U.S. self-employment tax even while making local social security contributions.

Foreign expenses still follow U.S. rules

A cost paid abroad can qualify, but it must be translated into U.S. tax terms.

Keep records of:

• The original foreign-currency amount
• The U.S. dollar conversion
• The exchange-rate source and method
• The business purpose
• Any VAT or sales tax included
• Any VAT subsequently recovered

Recoverable VAT is not ultimately your business cost. Unrecoverable VAT can form part of the cost of the related expense.

An item deductible under local law is not automatically deductible on a U.S. return—and the reverse can also be true.

Foreign businesses can create additional forms

Registering a company abroad can change much more than the deduction calculation.

Depending on its U.S. classification and your ownership, a foreign business can create obligations involving:

• Form 5471
• Form 8858
• Form 8865
• Form 8938
• FBAR
• Form 8621
• Other international information returns

At Bright!Tax, we do not assume that someone is a sole proprietor simply because they describe themselves as self-employed. We first look at the legal entity, ownership and any elections that affect its U.S. treatment.

How do you report self-employment deductions?

The forms depend on your business structure and the tax breaks you claim.

Form or schedule	What it does
Schedule C	Reports income and expenses from a sole proprietorship or qualifying single-member LLC
Schedule SE	Calculates self-employment tax
Form 1040	Reports your overall individual tax position
Form 8995 or 8995-A	Calculates the qualified business income deduction
Form 1116	Claims an eligible Foreign Tax Credit
Form 2555	Claims the Foreign Earned Income Exclusion or foreign housing deduction
Form 8829	Calculates qualifying home-office expenses under the actual-expense method in applicable cases

For many sole proprietors, the basic flow is:

1. Report business income and deductible expenses on Schedule C.
2. Use the resulting profit to calculate net earnings and self-employment tax on Schedule SE.
3. Carry the relevant amounts to Form 1040 and its schedules.
4. Apply other deductions, exclusions and credits where appropriate.

Self-employed expats may also need to make estimated tax payments. These are commonly required when you expect to owe at least $1,000 after subtracting withholding and refundable credits, although other safe-harbor rules and exceptions apply.

Keep records including:

• Invoices
• Receipts
• Bank and card statements
• Contractor payments
• Currency conversions
• Mileage logs
• Travel records
• Home-office calculations
• Estimated-tax payments
• Certificates of coverage

When should self-employed expats work with a tax professional?

A straightforward sole-proprietor return can be manageable. Once income, expenses, entities and social security obligations cross borders, the questions multiply quickly.

Professional help is particularly valuable when:

• You have recently become self-employed abroad
• You claim the FEIE or Foreign Tax Credit
• You pay foreign social security contributions
• You need to establish whether a totalization agreement applies
• You own or operate through a foreign company
• You have employees or contractors in more than one country
• You are behind on U.S. filings
• You have significant mixed personal and business expenses
• You need to coordinate local and U.S. tax treatment

Bright!Tax works with freelancers, consultants, contractors and business owners around the world. We can help determine which expenses belong on Schedule C, whether a totalization agreement changes your self-employment tax and how the business fits into the rest of your U.S. return.
