The 2027 numbers
Every federal figure that resets for 2027, in one place. Each one says whether it is projected or confirmed, and when the official version arrives.
In shortMost 2027 figures are not announcements — they are formulas. The tax brackets, the IRMAA thresholds and the COLA are all set by an inflation calculation written into law, so they can be computed months before an agency publishes them. That is what this page tracks:7 figures still projected, 5 already confirmed. Nothing here is presented as official until it is.
When each 2027 number becomes official
| Figure | Who publishes it | When |
|---|---|---|
| Social Security COLA | SSA | Mid-October 2026 |
| Tax brackets and standard deduction | IRS | Late October 2026 |
| 401(k) and IRA contribution limits | IRS | Late October / early November 2026 |
| Medicare Part B premium and deductible | CMS | November 2026 |
| IRMAA income brackets | CMS | November 2026 |
| State minimum wages | State agencies | Effective January 1, 2027 |
