Every fall the IRS resets the numbers that shape next year's money moves. This hub tracks all of them in one place: what's official, what's still projected, and when each IRS release is due. Right now only the 2027 HSA limits are final. We flip each page to official numbers the day the IRS posts them.

🔍 How we label numbers
Official IRS means the figure is in an IRS revenue procedure, notice or news release, linked in the sources. Projected means a published estimate that applies the inflation formula in the tax code to government price data (we name whose estimate on each page). Projections can be off by a step or two of rounding, so don't treat them as final.
