Ohio ODJFS issues more SUI rate notices than almost any other state. Missing the 30-day protest window means overpaying for an entire year. Here is your complete timeline and checklist.
If you employ people in Ohio, ODJFS sends you a contribution rate notice every year — and the clock it starts is one of the least forgiving in employer compliance. Miss the protest window and the assigned rate stands for the entire year, whether or not the underlying numbers are right. This guide covers the Ohio timeline, what to check in the first week, and the checklist to run before the window closes.

ODJFS calculates next year's contribution rates from your account's reserve ratio — the balance of contributions paid minus benefits charged, divided by your average annual payroll — and mails annual rate notices at the end of the year. Two things matter the moment it arrives: the assigned rate, and the mailing date, because the protest window runs from the mailing date, not from whenever the notice surfaced in the mail pile.
Ohio employers can request a rate review within the window stated on the notice — 30 days from mailing. That window is your only chance to correct the rate for the coming year. After it closes, even a provably wrong rate generally stands until the next annual cycle, which means an error does not cost you once — it costs you across every taxable dollar of every employee for a full year.
Ohio allows voluntary contributions — a one-time payment into your account that can lift your reserve ratio into a lower rate bracket. Whether it pays off is pure arithmetic on your rate table position, and the answer is sometimes a payback measured in months. The deadline is January 31, so the VC analysis belongs in the same year-end sprint as the rate review. Run your numbers with the VC calculator or read the full ROI guide.
Pull your benefit charge statements and your taxable wage history, and recompute the reserve ratio ODJFS used. The common errors: benefit charges from claims that were never yours, wages attributed to the wrong account after a restructure, and successorship transfers applied incorrectly. If any input is wrong, the rate built on it is wrong.
Confirm the new rate is actually configured in payroll for January 1 forward. A payroll system still running last year's rate is the quietest and most common failure — if the old rate was lower, you are underpaying and accruing an assessment; if higher, you are donating the difference. Our SUI rate calculator shows what a tenth of a point costs across your headcount.
If the numbers do not reconcile, file the rate review request in writing before the window closes, with the wage and charge evidence attached. If the numbers are right but you sit near the bottom of a rate bracket, run the voluntary contribution analysis before January 31. Do both with time to spare — mailing-date windows do not grant extensions for busy Decembers.
On the overpayment side there is no penalty — just money gone. On Ohio's $9,000 wage base, a half-point of unnecessary rate across 50 employees is $2,250 every year it goes uncorrected. The SUI overpayment audit guide walks through catching exactly that.
When the ODJFS notice arrives: (1) record the mailing date and calendar the protest deadline; (2) recompute the reserve ratio from your charge and wage history; (3) audit the benefit charges line-by-line; (4) confirm payroll is configured with the new rate and the $9,000 base; (5) run the voluntary contribution analysis before January 31; (6) if anything is off, file the review request in writing — inside the window.
Kreto runs this checklist as software: upload the notice, and it reads the rate, verifies it against your uploaded payroll data, quantifies any discrepancy in dollars, tracks the protest deadline, and drafts the review request for your approval. Start with a free notice scan.
Kreto classifies it, verifies it against payroll, and tells you exactly what to do. No credit card required.
