What's Changing in 2026
In December 2025, the Social Security Administration announced a 2.8% cost-of-living adjustment effective January 2026. If you're already receiving benefits, your monthly payment will increase automatically to keep pace with inflation. The adjustment applies to retirement, survivor and disability benefits alike.
Separately, in July 2025, Congress passed the One Big Beautiful Bill, which includes a new $6,000 standard deduction for individuals aged 65 and older. This deduction reduces your taxable income on your US federal return, which can lower the amount of your Social Security benefit subject to tax — particularly relevant if you have other income that pushes you into the thresholds where benefits become taxable.
Both changes are federal US measures. Neither alters Swiss tax law, the US-Swiss tax treaty, or your reporting obligations as a US person abroad. Understanding how they interact with your dual-system reality is the key.
How the 2.8% COLA Affects Your Monthly Benefit
The COLA is straightforward: your January 2026 payment will be 2.8% higher than your December 2025 payment. No action required; the Social Security Administration applies it automatically. If you receive your benefit by direct deposit to a US bank account or via international transfer, you'll see the new amount on your January statement.
Currency Considerations
If you convert your dollar benefit to Swiss francs for living expenses, the real purchasing-power gain depends on the exchange rate as well as the COLA percentage. A 2.8% increase in dollars may feel smaller or larger in francs depending on how the currency moves.
The adjustment does not change your filing obligations. You still report worldwide income to both the IRS and the Swiss tax authorities. The larger benefit simply means a higher number on the income lines of both returns.
The New $6,000 Senior Tax Deduction: Who Qualifies and What It Does
The new deduction applies to US taxpayers aged 65 or older. It increases your standard deduction by $6,000, effectively reducing the amount of income subject to federal tax. For 2026, if you're single and 65 or older, your total standard deduction rises to approximately $21,000 (the regular standard deduction plus the new senior amount). For married couples filing jointly where both spouses are 65 or older, the combined increase is $12,000.
Why does this matter for Social Security benefits? Because the US taxes Social Security using a two-tier formula: up to 50% of your benefit can be taxable if your combined income exceeds $25,000 (single) or $32,000 (married filing jointly), and up to 85% can be taxable above $34,000 (single) or $44,000 (married filing jointly). Combined income means your adjusted gross income, plus non-taxable interest, plus half your Social Security benefit.
A higher standard deduction reduces your taxable income after these thresholds are applied. It won't eliminate the inclusion of Social Security in the calculation, but it can lower your final tax bill — particularly if you have pension income, investment income, or are taking distributions from retirement accounts.
Not a Credit
The $6,000 is a deduction, not a tax credit. It lowers the income on which you pay tax; it doesn't reduce your tax dollar-for-dollar. The actual tax savings depend on your marginal rate and total income picture.
How Social Security Is Taxed Under the US-Swiss Tax Treaty
If you're a US citizen resident in Switzerland, Article 19 of the US-Swiss tax treaty generally assigns taxing rights on Social Security benefits to Switzerland, your country of residence. This means you report the benefit as income on your Swiss tax return, and Switzerland taxes it according to Swiss rules.
The US, however, still considers you a US taxpayer because of your citizenship. You must report your worldwide income — including Social Security — on your US federal return. The treaty prevents true double taxation by allowing you to claim a foreign tax credit on your US return for Swiss taxes paid on the same income, but the mechanics matter.
- You include your Social Security benefit in gross income on both the US and Swiss returns.
- On the US side, you calculate how much of the benefit is taxable using the standard formula (up to 85% depending on other income).
- You then claim the foreign tax credit for Swiss taxes paid, which usually eliminates or sharply reduces US tax owed on that income.
- The new $6,000 deduction reduces your US taxable income before you apply the credit, potentially lowering the amount of foreign tax credit you need or freeing up credits for other income.
In practice, many Americans in Switzerland owe little or no US federal tax on Social Security after the foreign tax credit, but filing accurately and understanding how treaty benefits apply remains essential to avoid penalties and optimize your position.
Swiss Tax Treatment: No Automatic Deduction Portability
The $6,000 senior deduction is a US federal tax measure. It does not apply to your Swiss tax return. Switzerland has its own deductions and allowances for pensioners, which vary by canton and are unrelated to US law changes.
On your Swiss return, you report your Social Security benefit as foreign pension income. The amount is the full annual benefit received, converted to Swiss francs at the applicable rate. Swiss tax authorities do not care about the US COLA percentage or the new US deduction — they assess your income and apply Swiss rules.
The coordination challenge: you're taxed in Switzerland on the gross benefit, then you report the same benefit in the US, apply the US inclusion formula and the new deduction, then credit Swiss tax back. The net result is that the treaty prevents double taxation, but the two systems don't mirror each other, and changes in one country don't automatically flow through to the other.
AHV and Social Security: Two Independent Systems
Swiss AHV (Alters- und Hinterlassenenversicherung) and US Social Security are separate pension systems. If you've worked in both countries, you may receive benefits from both. There is no totalization agreement between the US and Switzerland for US citizens, meaning your US work credits and Swiss AHV contributions don't combine to help you qualify for either benefit.
The 2026 COLA applies only to your US Social Security benefit. It has no effect on your AHV pension, which is adjusted according to Swiss federal policy. Similarly, the new US senior deduction affects only your US tax calculation — it doesn't change how Switzerland taxes your AHV or your US benefit.

Practical Planning Steps for 2026
Here's how to incorporate these changes into your financial routine without overcomplicating things.
Confirm Your Benefit Amount
Check your Social Security statement in January 2026 to verify the 2.8% increase was applied. If you haven't set up a my Social Security account online, do so — it's the easiest way to track your benefit, download statements, and update direct-deposit information from abroad.
Update Your Withholding if Desired
You can request voluntary federal income tax withholding from your Social Security benefit using Form W-4V. Some expats do this to avoid a tax bill at filing time, though many find they owe little or nothing after foreign tax credits. With the new $6,000 deduction potentially lowering your taxable income, you may want to revisit whether withholding still makes sense for your situation.
Track Both Currencies
Keep records of your benefit in US dollars and the Swiss franc equivalent for the tax year. You'll need the dollar amount for your US return and the franc amount for your Swiss return. Using consistent exchange rates (the year-end rate or average annual rate, depending on cantonal practice) simplifies reconciliation.
Coordinate With Other Retirement Income
If you're also drawing from a Swiss pillar 2 pension, pillar 3a withdrawals, or US retirement accounts, the interplay of these income sources with Social Security affects both your US taxable-benefit calculation and your Swiss marginal rate. The mechanics of Swiss pension taxation and US compliance are distinct and require careful reporting in both jurisdictions.
Don't Forget FBAR and FATCA
Receiving Social Security doesn't change your obligation to report foreign bank accounts if the aggregate balance exceeds $10,000 at any point during the year (FBAR) or to file FATCA forms if you meet the thresholds. These are separate compliance items, but they're part of the same dual-system reality.
No Automatic Foreign Tax Credit
The foreign tax credit isn't automatic. You must file Form 1116 with your US return to claim it. If you skip this step, you may pay US tax on income already taxed in Switzerland, even though the treaty entitles you to relief.
When the New Deduction Helps Most
The $6,000 senior deduction is most valuable if you have income beyond Social Security that pushes you into taxable territory in the US, but not so much income that you're already itemizing or that the standard deduction is irrelevant.
Scenarios where it makes a meaningful difference include receiving Social Security plus a modest pension or investment income, taking required minimum distributions from an IRA, or earning part-time self-employment income in retirement. In these cases, the extra $6,000 lowers your adjusted gross income, which can reduce the taxable portion of your Social Security benefit and your overall US tax before foreign tax credits.
If your income is low enough that you're already below the taxable thresholds, or high enough that Swiss taxes fully cover your US liability via foreign tax credits, the deduction may not change your bottom line — but it still simplifies the calculation and provides a cushion.
What Doesn't Change
- The US-Swiss tax treaty allocation of taxing rights remains the same: Switzerland taxes your benefit, the US allows a credit.
- Your obligation to file both a US federal return and a Swiss tax return continues unchanged.
- The method for calculating how much of your Social Security is taxable in the US (the combined-income formula) stays in place; the deduction applies after that calculation.
- Swiss cantonal tax rules and AHV adjustments are independent of US federal policy.
- FBAR, FATCA and other expat compliance requirements are unaffected by the COLA or the new deduction.
In other words: you get a bit more money each month and a potentially lower US tax bill, but the dual-system complexity you already manage doesn't go away.
Long-Term Considerations
If you're approaching retirement or already drawing benefits, these changes are worth folding into your broader planning. The COLA mechanism means your benefit adjusts yearly for inflation, which helps preserve purchasing power — though the real value depends on where and how you spend.
The $6,000 deduction is currently written into law for 2026 and beyond, but tax laws can change. Future Congresses could modify or repeal it, or adjust the thresholds for taxing Social Security. Planning on current rules while staying alert to changes is the practical approach.
For those thinking about estate and legacy planning, remember that Social Security benefits generally stop at death (except for survivor benefits), so they don't form part of your taxable estate. The focus is on lifetime tax efficiency and making sure you're not overpaying either government due to missed credits or misreported income.
Where to Get Help
These rules are educational context, not individual advice. Your actual tax outcome depends on your total income, filing status, canton of residence, and how you've structured retirement accounts and other assets.
If you're uncertain whether the new deduction applies to you, how to claim the foreign tax credit correctly, or how Swiss and US taxation of your combined retirement income should be coordinated, that's exactly the kind of question that requires personal analysis. A cross-border specialist who understands both systems can model your specific situation and help you file accurately in both countries.
