IRS 2027 FEIE, Tax Brackets, Deduction for Americans in Switzerland

The short version: projected 2027 inflation adjustments

As of mid-October 2026, the IRS has not released its official 2027 inflation adjustments. What you are seeing in early tax-planning articles are projections from the leading tax publishers — not final numbers. The projected 2027 figures are: the Foreign Earned Income Exclusion (FEIE — the amount of foreign salary or wages a qualifying American can exclude from US taxable income) rises from $132,900 to roughly $137,300; the standard deduction rises to about $16,600 for single filers and $33,200 for married filing jointly; and the income tax brackets expand by roughly 3.2% at most levels, compared with a 2.7% inflation adjustment used for 2026. For a deeper comparison of the choice that matters most in Switzerland, see FEIE vs. Foreign Tax Credit: The Switzerland Decision Guide for Americans.

What the 2027 projections show

Foreign Earned Income Exclusion (FEIE)

2026 official: $132,900 · 2027 projected: $137,300 (round)

Standard deduction: single

2026: $16,100 · 2027 projected: $16,600

Standard deduction: married filing jointly

2026: $32,200 · 2027 projected: $33,200

Standard deduction: head of household

2026: $24,150 · 2027 projected: $24,900–$24,950

Housing exclusion cap (part of FEIE package)

2026: $39,870 · 2027 projected: $41,130–$41,190

The tax rates themselves are not expected to change: the marginal rates remain 10%, 12%, 22%, 24%, 32%, 35% and 37%. What changes is how much income falls into each bracket. For a US filer in Switzerland with any US-taxable income left after the FEIE or foreign tax credit, the combination of a larger standard deduction and wider brackets means a slightly lower US tax bill at the margin. But the bracket change is usually far less important than the FEIE-vs-foreign-tax-credit decision.

Why the FEIE number still matters in Switzerland

Swiss income tax is generally high, so for many Americans in Switzerland the Foreign Tax Credit (Form 1116) is the better election: it credits Swiss tax paid against US tax, often eliminating the US liability entirely. The FEIE still matters, though, even when you don't use it as your primary shield. It matters because:

• In lower-tax cantons or for lower earners, the FEIE can be more valuable than the FTC.
• The FEIE amount sets the ceiling for the housing exclusion, which matters if you live in an expensive Swiss city and elect the FEIE.
• Choosing the FEIE rather than the FTC can change whether you keep the refundable Child Tax Credit.
• The FEIE is the ceiling before US tax stacks on top of Swiss tax — a higher FEIE can delay or reduce any residual US tax.

Retirement limits: why they may not move your Swiss return

Projections for 401(k), 403(b), 457 and IRA limits are also circulating: employee deferrals may rise to a projected $25,000–$25,500, with higher catch-up amounts for older savers, and IRA contributions are projected to rise to around $8,000. For most Americans in Switzerland, these numbers are less relevant because US retirement contributions generally require earned income that has not been excluded by the FEIE. If you use the FEIE to exclude all your Swiss salary, you typically cannot contribute to these accounts, regardless of the raised limits.

Housing exclusion: a Swiss angle worth watching

The housing exclusion is part of the FEIE package, not a separate deduction. The 2026 cap was $39,870, which is 30% of the 2026 FEIE. For 2027, publishers project a base amount near $21,968 and a cap in the $41,130–$41,190 range. In Swiss cities, that cap can matter if you elect the FEIE and your housing costs exceed the base amount. If you take the foreign tax credit instead, the housing exclusion does not apply, which is one of several trade-offs worth comparing before you decide.

What this means for your 2027 Swiss tax planning

If you currently use the FEIE, the projected higher exclusion gives you a little more room before US taxable income appears. If you use the foreign tax credit, the change may barely register because Swiss tax already eliminates most or all US tax. The more useful move now is to check whether your current election still makes sense for your Swiss situation, and to remember that you can change elections in some years with proper planning. For context on how last year's changes interacted with FEIE and IRS enforcement, see 2026 Tax Filing Season for Americans in Switzerland: FEIE Changes, IRS AI Enforcement, and What You Must Know.

A calm way to use these projections

Do not restructure anything based on a projection. Use these numbers for scenario planning, not final decisions. If the official 2027 FEIE comes in at $137,300 or a nearby figure, you can already see the direction: slowly rising exclusion, slightly larger brackets, and a standard deduction that quietly helps. The next step is not to panic or jump into a new election — it is to understand your Swiss tax position, your US filing choices, and whether the FEIE or the foreign tax credit better fits your actual numbers.
