Why This Site Sometimes Asks for Your Birth Month Instead of Just Showing a Date
Most of this site works the same way for every visitor to a given state page: pick your state, see the date, done. A handful of states don't work that way, and if you've landed on one of those pages wondering why we're asking for your birth month instead of just showing a date, here's exactly why — and why we won't guess it for you.
The simple case: one date, for everyone, codified in law
Most states renew every individual CPA on the same calendar date, full stop. Wisconsin is a clean example: every individual license renews December 15 of each odd-numbered year — "the same statutory date for every licensee," per Wis. Stat. § 440.08(2)(a)1. There's no formula to apply, no personal detail needed — the date on the page is your date, and it's a real, citation-backed fact this site verifies and marks Verified.
The other case: your date depends on something specific to you
Several states don't assign one date to everyone — they compute each licensee's own deadline from a personal detail, most often the licensee's own birth month:
- Texas: renewal fee is due annually by the last day of your own birth month.
- Oklahoma: "all permits issued shall be renewed on the last day of the individual's birth month" (Okla. Stat. tit. 59 § 15.14A) — the Board even publishes its own birth-month lookup table.
- New Mexico: annual renewal due by the last day of your birth month (16.60.3.9.I NMAC).
- California: your license expires every 2 years at midnight on the last day of your birth month — which two years depends on whether your birth year is odd or even.
- Arizona: biennial, matched to both your birth month and your birth year's odd/even parity (A.R.S. § 32-730, A.A.C. R4-1-345(B)(1)) — see our full Arizona guide for exactly how that works.
- New York: a mandatory triennial registration (separate from the license itself) that expires in the month before your own birth month.
These aren't small variations on the same idea — a birth-month formula, a birth- year-parity formula, and a fixed date that applies to everyone are three genuinely different mechanisms, and mixing them up is an easy way to track the wrong deadline entirely.
Why we ask instead of guess
This site's whole standard, described in full on our verification methodology page, is simple: if a date can't be confirmed against the actual codified rule for everyone in a state, we don't publish a guessed date. For a birth-month-driven state, "your deadline" genuinely doesn't exist as a single fact until you tell us the one detail the rule itself depends on. So instead of picking a plausible-looking date and hoping it's close enough, the signup form for these states asks for that one extra field — your birth month, or similar — and computes your actual deadline from it, the same way the state's own rule does.
Bottom line: if a state page shows an exact date with a Verified badge, that date is confirmed law, the same for every licensee. If it asks you a question first, that's not this site being vague — it's the actual rule working that way, and we'd rather ask than guess.
General orientation, not a citation. This guide draws on board rules and, where available, this site's own verified dataset — it isn't a primary source in itself. Last checked against those sources: August 4, 2026.
