Each year, most countries adjust their income tax brackets for inflation. Some also change rates, deduction amounts, or social contribution caps. This article documents every change FiscalFold tracks for the 2026 tax year across all six countries in our database.
United States
The IRS adjusts bracket thresholds, the standard deduction, and Social Security caps annually using chained CPI-U. For 2026:
Bracket Thresholds (Single Filer)
| Rate | 2025 Threshold | 2026 Threshold | Change |
|---|---|---|---|
| 10% | $0 | $0 | — |
| 12% | $11,925 | $12,400 | +$475 |
| 22% | $48,475 | $50,400 | +$1,925 |
| 24% | $103,350 | $105,700 | +$2,350 |
| 32% | $197,300 | $201,775 | +$4,475 |
| 35% | $250,525 | $256,225 | +$5,700 |
| 37% | $626,350 | $640,600 | +$14,250 |
Other US Changes
- Standard deduction: $15,000 → $16,100 (+$1,100)
- Social Security wage cap: $176,100 → $184,500 (+$8,400)
- Maximum Social Security tax: $10,918 → $11,439
- Medicare rate: Unchanged at 1.45% (+ 0.9% Additional Medicare above $200,000)
The $1,100 increase in the standard deduction is the largest single-year jump since the Tax Cuts and Jobs Act took effect. Combined with the bracket shifts, the average single filer earning $75,000 will see about $400-500 less in federal tax than under 2025 rules.
Canada
The CRA applies an annual indexation factor based on the average monthly CPI over a 12-month period ending September 30 of the prior year.
Federal Bracket Thresholds
| Rate | 2025 Threshold | 2026 Threshold | Change |
|---|---|---|---|
| 14% (was 15%) | $0 | $0 | rate cut |
| 20.5% | $57,375 | $58,523 | +$1,148 |
| 26% | $114,750 | $117,045 | +$2,295 |
| 29% | $177,882 | $181,440 | +$3,558 |
| 33% | $253,414 | $258,482 | +$5,068 |
Other Canada Changes
| Item | 2025 | 2026 | Change |
|---|---|---|---|
| Basic Personal Amount | $16,129 | $16,452 | +$323 |
| CPP max pensionable earnings | $71,300 | $74,600 | +$3,300 |
| CPP employee rate | 5.95% | 5.95% | unchanged |
| EI max insurable earnings | $65,700 | $68,900 | +$3,200 |
| EI employee rate | 1.64% | 1.63% | −0.01pp |
United Kingdom
The UK has been in a period of frozen thresholds since 2021. For 2026:
Income Tax Thresholds
| Band | Range (GBP) | Rate | Status |
|---|---|---|---|
| Personal Allowance | 0 - 12,570 | 0% | Frozen since 2021-22 |
| Basic rate | 12,571 - 50,270 | 20% | Frozen |
| Higher rate | 50,271 - 125,140 | 40% | Frozen |
| Additional rate | Above 125,140 | 45% | Unchanged for 2026 |
National Insurance Changes
| NI Band | Earnings Range (GBP) | Rate |
|---|---|---|
| Class 1 primary | 12,570 - 50,270 | 8% |
| Class 1 upper | Above 50,270 | 2% |
The UK's freeze on thresholds means that inflation continues to push more earners into higher brackets — a phenomenon known as fiscal drag. With cumulative inflation of roughly 20% since the thresholds were last raised, many workers find themselves paying higher effective rates on the same real income.
Germany
Germany adjusts its tax-free amount (Grundfreibetrag) and Social Security caps annually, but the progressive formula structure remains largely the same.
Key Changes
| Item | 2025 | 2026 | Change |
|---|---|---|---|
| Grundfreibetrag (tax-free) | 12,096 EUR | 12,348 EUR | +252 EUR |
| 42% threshold (Spitzensteuersatz) | ~68,430 EUR | ~69,878 EUR | +1,448 EUR |
| 45% threshold (Reichensteuersatz) | 277,826 EUR | 277,826 EUR | unchanged |
| Solidarity surcharge | High earners only | unchanged | |
Social Insurance
| Pillar | Employee Rate | 2026 Change |
|---|---|---|
| Pension (Rentenversicherung) | 9.3% | Ceiling: 7,550 → 8,050 EUR/mo |
| Health (Krankenversicherung) | ~7.3% + supplemental | Ceiling slightly increased |
| Unemployment | 1.3% | unchanged |
| Long-term care (Pflegeversicherung) | 1.8% / 2.3% | Childless: 3.4% → 3.6% |
Germany's Grundfreibetrag increase of 252 EUR translates to roughly 45 EUR less in tax per year at the lowest bracket — a modest adjustment. The more impactful change is the pension assessment ceiling increase, which means higher earners pay more in social contributions.
France
France revalues its brackets each year by the forecast consumer price index.
Income Tax Brackets (Per Part)
| Rate | 2025 Threshold | 2026 Threshold |
|---|---|---|
| 0% | 0 - 11,497 EUR | 0 - 11,600 EUR |
| 11% | 11,497 - 29,315 EUR | 11,600 - 29,579 EUR |
| 30% | 29,315 - 83,823 EUR | 29,579 - 84,577 EUR |
| 41% | 83,823 - 180,294 EUR | 84,577 - 181,917 EUR |
| 45% | Above 180,294 EUR | Above 181,917 EUR |
Social Contributions
| Contribution | Rate | 2026 Change |
|---|---|---|
| CSG | 9.2% | unchanged |
| CRDS | 0.5% | unchanged |
| Pension (CNAV) ceiling | — | 3,864 → 3,925 EUR/mo |
| AGIRC-ARRCO (complementary) | — | Follows SS ceiling |
France's total social contribution burden remains among the highest in our dataset — the combined employee-side deductions can reach 22-25% of gross salary. The bracket adjustments are modest, reflecting low but persistent inflation in the eurozone.
Spain
Spain's national (estatal) income tax brackets have been relatively stable, with most changes occurring at the autonomous community level.
National Income Tax Rates
| Taxable Income (EUR) | National Rate |
|---|---|
| 0 - 12,450 | 9.5% |
| 12,450 - 20,200 | 12% |
| 20,200 - 35,200 | 15% |
| 35,200 - 60,000 | 18.5% |
| 60,000 - 300,000 | 22.5% |
| Above 300,000 | 24.5% |
Spain is notable for splitting income tax between the national (estatal) and autonomous community (autonomica) portions. The rates above are the national component only. Combined with the autonomous portion, total marginal rates typically run 2x the figures shown — so the effective top rate is around 47-54% depending on the region.
Social Security
| Item | 2025 | 2026 |
|---|---|---|
| General regime employee rate | 6.47% (incl. 0.12% MEI) | 6.50% (incl. 0.15% MEI) |
| Maximum contribution base | 4,720.50 EUR/mo | 5,101.20 EUR/mo |
| Minimum contribution base | Linked to SMI (increasing annually) | |
The Big Picture
Across all six countries, the direction of change for 2026 is broadly the same: bracket thresholds are moving up with inflation, social contribution caps are rising, and headline rates are largely unchanged. None of the countries in our dataset introduced new tax brackets or made significant structural changes for the 2026 tax year.
The most impactful change is the US standard deduction jump to $16,100 — a $1,100 increase that directly benefits every single filer. The UK's continued threshold freeze is the most consequential non-change, as it represents an effective tax increase for anyone whose wages have kept pace with inflation.

Common questions
§ 09 / 09- What changed in US tax brackets for 2026?
- The seven rates stayed at 10/12/22/24/32/35/37%, but every threshold was indexed upward under IRS Rev. Proc. 2025-32. The standard deduction rose from $15,000 to $16,100 for single filers and to $32,200 for married filing jointly. The Social Security wage base climbed from $176,100 to $184,500, which raises the maximum Social Security tax an employee pays from $10,918 to $11,439 — so higher earners see a payroll tax increase even though no income tax rate changed.
- Which country cut income tax rates for 2026?
- Canada, most notably. The lowest federal bracket dropped from 15% to 14%, the first cut to the bottom rate in years, and the brackets were indexed 2.0% on top. The Basic Personal Amount rose to $16,452. Elsewhere the pattern was indexation rather than rate cuts: the US, Germany, France and Spain adjusted thresholds for inflation while leaving rates alone, and the UK kept its thresholds frozen — which raises tax in real terms without changing any published rate.
- Why does the UK collect more tax without raising rates?
- Threshold freezes, often called fiscal drag. The UK Personal Allowance has been held at £12,570 and the higher-rate threshold at £50,270 rather than rising with inflation. As wages grow, more of each person's income crosses into taxable territory and more people are pulled into the 40% band, so the effective tax rate rises every year even though the published rates of 20%, 40% and 45% have not moved. It is the least visible way to raise tax and, in the current period, one of the most significant.
- How do 2026 income tax rates compare across these six countries?
- Top marginal rates are closer than most people expect: 37% in the US, 33% federal in Canada before provincial tax, 45% in the UK, Germany and France, and 47% in Spain. What separates them is where those rates start and what sits underneath. Germany's 42% rate begins at just €69,878 while the US 37% rate needs $640,600. And social contributions — 7.65% in the US against 20–25% in Germany and France — move the effective burden far more than any bracket change did this year.
