What it did to a Social Security payment
The Part B premium is withheld from the Social Security payment, so it lands in the same January as the cost-of-living adjustment and the two move against each other. A $2,000 monthly benefit in 2025 became $2,056 gross with the 2.8% adjustment — a rise of +$56. After the premium went from $185.00 to $202.90, the payment rose +$38, an effective 2.09%.

| Gross monthly benefit | $2,000 | $2,056 |
| Part B premium | $185.00 | $202.90 |
| Net payment | $1,815 | $1,853 |

The 2026 income-related tiers
Anyone whose modified adjusted gross income on the 2024 tax return crossed the first threshold paid more than the standard premium. The adjustment is a flat dollar amount per tier, not a percentage of income, and it steps at the bracket boundary rather than phasing in.
| Single | Married filing jointly | Married filing separately | Adjustment | Total Part B | Part D adjustment |
|---|---|---|---|---|---|
| Up to $109,000 | Up to $218,000 | Up to $109,000 | none | $202.90 | none |
| $109,001 to $137,000 | $218,001 to $274,000 | — | $81.20 | $284.10 | $14.50 |
| $137,001 to $171,000 | $274,001 to $342,000 | — | $202.90 | $405.80 | $37.50 |
| $171,001 to $205,000 | $342,001 to $410,000 | — | $324.60 | $527.50 | $60.40 |
| $205,001 to $499,999 | $410,001 to $749,999 | $109,001 to $390,999 | $446.30 | $649.20 | $83.30 |

CMS computes each tier from the unrounded monthly actuarial rate, so exact reconstruction from the rounded standard premium is impossible. SPEC section 3.7 fixes the tolerance at $0.10, which holds for 2026 but is not the right bound generally: the standard premium carries up to $0.05 of rounding error, multiplying it by 3.4 propagates that to $0.17, and the dime rounding of the tier itself adds another $0.05. The bound is therefore per-tier. Never round the reconstruction, and never assert exact equality against it. Exact equality is asserted only between the committed tables and their Federal Register / POMS sources.
