Short answer: whether digital nomad health insurance is tax deductible depends almost entirely on where the nomad is filing, not on the insurer or the itinerary. In the United States, self-employed nomads filing a Schedule C can generally deduct qualifying premiums above the line under the self-employed health insurance deduction, subject to specific eligibility rules and business-net-income limits. In the United Kingdom, HMRC treats personal medical insurance for sole traders as a private expense that fails the "wholly and exclusively" trade test, so it is rarely deductible. In Portugal, health insurance premiums are not treated as a business expense for freelancers under the standard IRS categories, and the personal health-expense credit only covers actual medical costs, not most international insurance premiums.
This article walks through each of those regimes in turn, with the paperwork the US actually asks for when the plan and the nomad are both offshore, and the traps that catch remote workers who assume the deduction travels with them. Figures cited are current as of 2026; verify anything material with a licensed adviser in the relevant jurisdiction before filing.
What "digital nomad health insurance" usually means
The term covers a wide range of products, and the tax treatment can hinge on which one is actually held:
- International private medical insurance (IPMI): annual plans from providers such as Cigna Global, Allianz Care, GeoBlue, IMG, or April International. Global or multi-region coverage; often the plan a longer-term nomad settles on.
- Travel medical insurance: short-duration trip cover from SafetyWing, World Nomads, IMG Patriot, and similar. Written as travel insurance rather than health insurance in most jurisdictions.
- ACA marketplace plans: US-based individual health plans purchased through Healthcare.gov or a state exchange. Only meaningful for nomads who retain a US home state and are physically present in the US enough to actually use the network.
- Foreign national or resident health insurance: a domestic plan taken out in the country of residence (for example, a Portuguese ADSE-style plan or a private complementar).
Tax authorities generally do not care about the marketing label. They care about who the insured is, who paid the premium, whether the plan is established under a trade or business, and whether the coverage qualifies as "medical care" under local law. Those questions have different answers in each of the three jurisdictions below.
United States: the self-employed health insurance deduction
Under Internal Revenue Code §162(l), a self-employed individual can deduct 100% of premiums paid for medical, dental, and qualifying long-term care insurance for themselves, their spouse, dependents, and non-dependent children under age 27 as of the end of the tax year. The deduction is taken as an adjustment to gross income (above the line, on Schedule 1), not as an itemized medical expense on Schedule A. That distinction matters: the itemized route only helps when total medical expenses exceed 7.5% of AGI, so the above-the-line route is far more valuable when it applies.
The United States taxes citizens and green card holders on worldwide income regardless of where they live, so a nomad who has not renounced remains a US filer. The federal individual tax structure — a progressive 10-37% federal bracket, with state taxes 0-13.3% on top — was made permanent by the One Big Beautiful Bill Act signed 4 July 2025, so the deduction continues to sit against the same rate schedule most nomads have been planning against. See the United States country page for the full 2026 bracket and residency test detail.
Who qualifies as "self-employed" for this purpose
The deduction is available to:
- Sole proprietors filing a Schedule C with net profit for the year;
- Partners in a partnership with net earnings from self-employment;
- Members of an LLC taxed as a partnership or disregarded entity, on the same basis;
- More-than-2% shareholders of an S corporation, if the premium is paid by the S corp and included in W-2 Box 1 wages.
A Schedule C nomad is squarely inside the target population. What matters is that the trade or business generated net earnings from self-employment for the year, and that the health plan is "established under" that trade or business. The IRS accepts a plan in the individual's own name provided the business either pays the premium directly or reimburses the individual and the reimbursement runs through the books.
Key limits and disqualifiers
- Net earnings ceiling. The deduction cannot exceed net earnings from self-employment for the year, reduced by the deductible portion of self-employment tax and any qualifying contributions to self-employed retirement plans. A loss year zeros the deduction.
- Employer-plan lockout. No deduction is allowed for any month in which the nomad, spouse, or dependents were eligible to participate in a subsidized health plan maintained by any employer of the nomad, the spouse, a dependent, or a non-dependent child under 27. The test is monthly and eligibility-based, not enrolment-based — a spouse who could have joined a subsidized employer plan blocks the deduction for that month.
- FEIE interaction. Premiums allocable to income excluded under the Foreign Earned Income Exclusion cannot also generate a deduction. The FEIE is $132,900 for 2026 per the TaxAtlas US data. For nomads leaning heavily on FEIE, this can materially compress the SEHID benefit; TaxAtlas's FEIE vs Foreign Tax Credit comparison lays out the trade-off in detail.
- Marketplace subsidy interaction. Nomads with ACA marketplace coverage and advance premium tax credits face a circular calculation between the SEHID and the PTC. The IRS provides a simplified iterative method in Publication 974.
Does the insurer need to be based in the US?
No. IRC §162(l) does not require a US-domiciled insurer. It requires that the plan constitute "insurance" providing "medical care" as defined in §213(d). A well-structured IPMI plan from a mainstream global carrier — with defined premiums, defined benefits, and coverage of medical services rather than pure indemnity or travel-accident cover — generally satisfies the definition. Pure travel accident or trip-interruption cover typically does not, because the primary purpose is not medical care.
The safer defaults for nomads relying on the deduction are annual IPMI plans issued by regulated carriers, in the name of the individual (or spouse/dependents), with clearly itemized premium amounts and evidence of payment from a business or personal account that is reconciled to the Schedule C.
Paperwork the IRS actually asks for
The deduction is reported on Schedule 1, Line 17 (as of the 2025 form; line numbers occasionally shift). The IRS does not require the underlying documents to be filed with the return, but on audit or notice review, a self-employed nomad claiming the deduction on a foreign-issued policy should be able to produce:
- The policy schedule or certificate of insurance, showing insured name(s), coverage type, effective dates, and premium amount in the original currency;
- Proof of payment for each premium period — bank or card statements matching the amount, converted to USD at the yearly average or the payment-date spot rate (be consistent with the method used elsewhere on the return);
- The Schedule C or Schedule K-1 that establishes net earnings from self-employment for the year;
- Evidence that the plan was "established under" the trade or business — most commonly, the business bank account paying the premium, or a documented reimbursement policy;
- Confirmation that no month of eligibility for a subsidized employer plan applied — a spouse's HR letter is often the cleanest evidence when relevant;
- Any FEIE or Foreign Tax Credit computation, so the allocation between excluded and non-excluded income is clear.
Nomads who file the streamlined package, use Form 2555 for FEIE, and hold offshore accounts should also keep the SEHID substantiation with their FBAR/FATCA file. The US citizen moving abroad tax guide covers those interlocking obligations in one place.
United Kingdom: sole-trader treatment is much less friendly
The UK taxes residents on worldwide income on the arising basis from 6 April 2025, following the abolition of the non-domicile regime; the new four-year Foreign Income and Gains (FIG) regime is far narrower than the old remittance basis, as the United Kingdom country page sets out. The top marginal rate is 45%, with National Insurance layered on top for the self-employed.
For sole traders and partners, HMRC applies the "wholly and exclusively" test at ITTOIA 2005 s.34. Private medical insurance premiums are almost always treated as failing that test, because the coverage protects the individual personally — health is an inherently personal attribute — not the trade. HMRC's manual guidance is long-standing: the fact that being ill would interrupt the trade is not enough to make the premium a trade expense.
Two narrow exceptions exist and are worth flagging so that nomads do not over-read them:
- Overseas working medical expenses. HMRC accepts a deduction for the cost of medical treatment or insurance specifically required to allow the sole trader to work in a country where medical care would not otherwise be available on reasonable terms — for example, insurance covering an emergency evacuation from a remote location where treatment could not be obtained locally. The concession is narrow and evidence-driven, not a general permission to deduct IPMI.
- Ltd company route. A UK limited company can pay for a director's private medical insurance and deduct the premium as a business expense, but the director then has a benefit in kind reportable on the P11D and subject to Class 1A NICs. The net effect is often no better than paying personally out of already-taxed income, and can be worse depending on marginal rate.
For most UK-resident nomads operating as sole traders, the practical answer is that international health insurance is not deductible against self-employment profits, and the plan should be budgeted as a personal cost.
Portugal and other EU residency: business-expense treatment is limited
Portuguese personal income tax (IRS) is progressive to 48%, with a solidarity surcharge on top; the Portugal country page has the full band structure. Self-employed individuals report under Category B, either through the simplified regime (which applies a fixed coefficient to gross income and does not permit itemized expense deductions in the usual sense) or through organized accounts.
Under the simplified regime, no separate deduction is available for health insurance premiums — the coefficient (typically 0.75 for professional service income) already builds in an assumed expense ratio, and additional itemized deductions above a residual amount are not permitted. Under organized accounts, a business expense is only deductible if it is incurred to obtain business income and properly documented. Health insurance premiums covering the individual are treated as a personal expense in the same spirit as the UK "wholly and exclusively" test, and are generally not accepted.
Portuguese IRS does provide a personal (not business) tax credit for health expenses at 15% of qualifying expenses up to €1,000 in credit per household, but this covers actual medical costs and premiums paid on VAT-exempt policies — many international IPMI plans issued outside Portugal do not qualify, and the credit is materially smaller than the business deduction a Schedule C filer in the US would receive.
Nomads on the IFICI (NHR 2.0) regime face the same treatment on the deduction side — the flat 20% rate applies to qualifying Portuguese-source employment or self-employment income, but the deduction rules are unchanged. The Digital Nomad Visa (D8) itself confers no tax benefit and does not by itself qualify a nomad for IFICI.
Other high-tax EU jurisdictions follow broadly similar logic for freelancers: France, Germany, Spain, and Italy each restrict deductibility of personal health insurance to specific statutory categories (typically supplementary cover linked to the state system), rather than treating an international private plan as a trade expense. Country-specific advice is essential; the general takeaway is that Continental European personal tax systems rarely mirror the US SEHID.
Three jurisdictions at a glance
| Item | United States (Sch C) | United Kingdom (sole trader) | Portugal (Category B) |
|---|---|---|---|
| Business-expense deduction for personal health insurance | Yes — SEHID, 100% of qualifying premium above the line | Generally no (fails "wholly and exclusively") | Generally no (personal expense; simplified regime uses fixed coefficient) |
| Cap on deduction | Net earnings from self-employment for the year | N/A — deduction rarely available | N/A — deduction rarely available |
| Foreign insurer accepted | Yes, if plan meets §213(d) "medical care" definition | Immaterial — deductibility is the blocker | Personal health-expense credit requires qualifying VAT-exempt Portuguese cover |
| Personal (non-business) credit or relief | Itemized Schedule A above 7.5% AGI threshold | Very limited; historic relief long since withdrawn | 15% credit on health expenses, capped at €1,000/household |
| Ltd company / corporate route | S corp: premium via W-2 works; C corp: fringe benefit rules | Ltd company deducts, but P11D benefit in kind for director | Company can cover, but treated as employment income for director |
Common mistakes nomads make on this deduction
- Assuming the SEHID is portable to other systems. The US deduction is unusually generous. Nomads who spent years claiming it as US-resident freelancers often assume the equivalent exists after moving to the UK, Ireland, Germany, or Portugal. In most cases it does not.
- Claiming SEHID in a loss year. The deduction is capped at net earnings from self-employment. A year with a net loss on Schedule C produces zero SEHID no matter how large the premium.
- Ignoring the spouse employer-plan test. A spouse eligible for a subsidized employer health plan disqualifies the SEHID on a month-by-month basis, even if the spouse never enrolled.
- Double-counting FEIE-excluded income. The portion of premiums allocable to excluded foreign earned income must be removed from the SEHID. Nomads maxing the FEIE often see a much smaller net deduction than the premium suggests.
- Treating travel insurance as health insurance. Trip-cancellation, baggage, and short-stay accident policies are not "insurance for medical care" for §162(l) purposes. Only the medical component of a genuine health plan qualifies.
- Weak substantiation for foreign-currency premiums. Payments in EUR, GBP, THB, or MXN should be converted using a documented method — annual average or spot rate at payment date — and the method should be applied consistently across the return.
- Overlooking dual residency. A nomad who inadvertently becomes tax resident in a second country (see the tie-breaker analysis in the tax planning guide for remote workers) may find that the second country's rules override the assumed home-country deduction.
