The Short Answer: Rarely, and Here's Why
Yes, your mandatory KVG premiums (the basic Swiss health insurance every resident is required to carry) technically qualify as medical expenses under US tax rules. IRS Publication 502 confirms that foreign health insurance premiums count the same way domestic ones do. The problem isn't whether they qualify — it's whether claiming them actually changes what you owe. For most Americans in Switzerland, the honest answer is no, and understanding why saves you from chasing a deduction that was never going to move the needle.
How the IRS Treats Medical Expenses for Americans Abroad
Medical expenses, including foreign insurance premiums, only reduce your US tax bill if two conditions are both met. First, you have to itemize deductions on Schedule A instead of taking the standard deduction — the flat amount every filer can claim without listing anything. Second, only the portion of your total medical expenses above 7.5% of your adjusted gross income (AGI, essentially your income after certain adjustments) is deductible at all. Everything below that threshold simply doesn't count, no matter how legitimate the expense.
7.5%
of your AGI is the floor — only medical costs above this amount are deductible, and only if you itemize
Here's what that looks like in practice. If your AGI is $100,000, the first $7,500 of medical expenses for the year aren't deductible under any circumstances — you'd need costs above that amount before a single dollar counts. A typical KVG premium runs roughly CHF 300 to 500 a month, which translates to somewhere around $3,600 to $6,000 a year. On its own, that rarely gets you anywhere close to clearing a 7.5% AGI threshold, even before you consider whether itemizing makes sense in the first place.
Why Itemizing Usually Doesn't Help If You Use the FEIE or Foreign Tax Credit
Most Americans working in Switzerland use one of two tools to avoid double taxation: the Foreign Earned Income Exclusion (FEIE), which lets you exclude a set amount of foreign wages from US tax each year, or the Foreign Tax Credit (FTC), which credits the Swiss tax you've already paid against your US liability. Either one typically brings your US tax bill to zero or close to it — without you needing to itemize anything. If the standard deduction already gets you to the same result as itemizing, there's no reason to track and substantiate medical expenses at all. For a broader look at how these mechanics play out on your actual filing, see our rundown of the 2026 tax filing season for Americans in Switzerland.
Even for the smaller group of filers where itemizing might make sense — say, a high-deductible year with a major medical event — KVG premiums alone are unlikely to be the deciding factor. You'd generally need them stacked alongside other significant medical costs: dental work, physical therapy, out-of-pocket procedures, or a high franchise (the Swiss term for your annual deductible) year. The premium alone almost never carries the load.
The Self-Employed Exception: A Deduction That Actually Works
There's one genuine exception worth knowing about. If you're self-employed, IRC Section 162(l) allows you to deduct 100% of your health insurance premiums — including foreign premiums like KVG — as an above-the-line deduction on Schedule 1, claimed via Form 7206. This is fundamentally different from the Schedule A route: it doesn't require itemizing, and there's no 7.5% AGI floor to clear. For self-employed Americans in Switzerland, this can be a meaningful, straightforward benefit. If you're weighing self-employment against salaried work here, our guide to self-employment in Switzerland as a US citizen covers the broader tax mechanics that come with that choice.
The cap that trips people up
The self-employed premium deduction can't exceed your net self-employment income after you've applied the FEIE exclusion, per Rev. Rul. 91-26. If your FEIE exclusion wipes out most of your net income for US tax purposes, there may be little or nothing left against which to deduct the premium. Whether this works in your case depends on your specific numbers — this is a good moment to get personal advice rather than assume the deduction applies at full value.
The Swiss Side: KVG Premiums Are Deductible There
While the US picture is limited, the Swiss side is more generous. KVG premiums are deductible on your cantonal tax return, subject to caps that vary by canton, plus a separate federal deduction. Medical expenses above 5% of net income are also deductible on the Swiss return, similar in spirit to the US 7.5% AGI floor but with a lower bar and different mechanics.
- Zurich: cantonal cap of CHF 2,600 (single) / CHF 5,200 (married)
- Vaud: cantonal cap of CHF 3,100 (single) / CHF 6,200 (married)
- Geneva: cantonal cap of CHF 3,366 (single) / CHF 6,732 (married)
- Federal deduction: capped at CHF 1,800 (single) / CHF 3,600 (married), plus CHF 600 per child
Putting the Two Systems Together
There's no double-dip here, and that's fine — the two systems simply aren't linked. Your Swiss deduction lowers your Swiss taxable income and has no bearing on your US return; your US treatment depends entirely on the itemize-versus-standard-deduction math and, for the self-employed, the Section 162(l) pathway. Since premiums have been trending upward in recent years, it's worth revisiting this calculation periodically rather than assuming last year's numbers still hold — our piece on Swiss health insurance premiums rising in 2027 walks through what higher premiums mean for your budget and your filing.
What This Means for Your Filing
If you're a salaried employee using the FEIE or FTC, don't spend energy chasing the KVG deduction on Schedule A — the math almost never works in your favor, and the standard deduction is doing its job. If you're self-employed, the Form 7206 route is worth exploring properly, with attention to the net-income cap. Either way, the goal isn't to find a clever workaround; it's to understand which rule actually applies to your situation and file with confidence instead of second-guessing yourself every April.
Two systems, one plan
At US Expat Wealth, we work specifically with Americans navigating both the US and Swiss systems at once — this kind of cross-border detail is exactly where the two sets of rules stop lining up neatly. None of this is individual tax advice; your own filing depends on your income, employment status, and deductions, so treat this as a starting point for a conversation, not a final answer.
Bottom Line
KVG premiums are a real medical expense in the eyes of the IRS, but that's rarely enough to make them useful on your US return. The FEIE and Foreign Tax Credit already do the heavy lifting for most employees, the 7.5% AGI threshold is a high bar for premiums alone, and the one clear win — the self-employed above-the-line deduction — comes with its own cap. None of this is a mistake on your part; it's simply two systems that were never designed to talk to each other, and knowing that is most of the battle.
