Frequently Asked Questions

When are new tax year brackets announced?

The IRS typically publishes inflation-adjusted bracket thresholds, standard deduction amounts, and other figures in October or November of the prior year via a Revenue Procedure. Canada's CRA publishes similar updates before the start of each tax year.

What does "provisional" mean for tax data?

Provisional data means we have modeled the values based on carry-forward rates or preliminary announcements, but the official final publication has not yet been confirmed. Provisional values should be treated as directional estimates.

How can I report an error in the tax data?

Email [email protected] with the jurisdiction, year, and the value you believe is incorrect. Include a link to the official source if possible. We aim to verify and correct reported issues within a few days.
