2027 figures
CMS has not announced the 2027 Part B premium, deductible or Part D amounts. They will appear here when CMS publishes them.
2027 income thresholds Calculated from BLS data · CMS confirmation pending
Calculated with the formula in the Social Security Act from BLS CPI-U for September 2025 to August 2026. The same calculation reproduces CMS's thresholds for 2026 and earlier years. One month of the index, October 2025, was never published, and CMS has not said how it will treat it, so where the result depends on that month both figures are shown.
| Bracket (2026 individual amount) | Individual tax return | Joint tax return | ||
|---|---|---|---|---|
| 11 published months | With October 2025 at 325.604 | 11 published months | With October 2025 at 325.604 | |
| Above $109,000 in 2026 | $112,000 | $224,000 | ||
| Above $137,000 in 2026 | $142,000 | $141,000 | $284,000 | $282,000 |
| Above $171,000 in 2026 | $177,000 | $176,000 | $354,000 | $352,000 |
| Above $205,000 in 2026 | $212,000 | $211,000 | $424,000 | $422,000 |
How this works
- Most people with Medicare Part B pay the standard premium. People whose modified adjusted gross income, as reported on their IRS tax return from 2 years ago, is above the amounts shown pay the standard premium plus an income-related monthly adjustment amount (IRMAA). For 2026, that is the 2024 tax return.
- People who pay the Part D income-related monthly adjustment amount pay it in addition to their Part D plan premium. Plan premiums vary by plan.
- Social Security tells people if they have to pay a higher premium because of their income. Someone who has had a life-changing event that reduced their household income can ask Social Security to lower the additional amount.
- CMS sets the premium, deductible and income amounts each year under the Social Security Act and usually announces the next year's figures in the fall. Medicare.gov has more.
Methodology
- Source
- Centers for Medicare & Medicaid Services — Medicare Parts A & B premiums and deductibles fact sheet
- Update cadence
- Annual (CMS usually publishes the next year's figures in the fall). Checked every 24 hours, and every hour in October, November and December until CMS publishes the next year's figures.
- Last updated
- Oct 7, 2026, 5:30 AM ET
- How it is produced
- The premium, deductible and income tables come from CMS's annual fact sheet. Before publishing, each total must equal the standard premium plus its adjustment, amounts must rise with income, and joint-return thresholds must be twice the individual ones. The Federal Register's annual Part B premium notice is checked too, to notice next year's publication. If figures for a year ever change, the update is held until the editor has checked why.
- Calculated thresholds
- Until CMS publishes, next year's income thresholds are calculated from BLS CPI-U (U.S. city average, all items, not seasonally adjusted, series CUUR0000SA0) as the Social Security Act sets out: each base amount ($85,000, $107,000, $133,500 and $160,000) rises by the percentage the average index for the 12 months ending with August of the preceding year exceeds the average for the 12 months ending with August 2018, rounded to the nearest $1,000; joint-return amounts are twice those. This reproduces CMS's thresholds for 2020, 2021, 2024, 2025 and 2026 exactly, and calculated figures are shown only while it reproduces the latest year. They are labelled as calculated and replaced by CMS's figures when CMS publishes; if CMS's figure differs, the page says so.
