Michigan IRP: One Lansing Office, Everything Online

Quick Answer

Michigan IRP is run by the Department of State’s IRP Unit in Lansing (517-335-6119, SOSIRP@Michigan.gov) — Secretary of State branch offices cannot handle apportioned registration at all. Transactions run online 24/7 at michigan.gov/irp through MiLogin for Business. Registrations are staggered by the month the account opened, expiring on the last day of the month with renewal materials 60 days out. For the 2290, Michigan publishes generous windows: from July 1 to September 30 proof from either tax year is accepted; from October 1 the current year is required; and vehicles registered within 60 days of purchase need no proof.

Michigan centralizes apportioned registration completely: one IRP Unit in Lansing issues every plate and cab card, and the branch offices that handle ordinary Michigan renewals cannot assist with IRP at all. The carrier-facing channel is the Secretary of State’s online services, entered at michigan.gov/irp and authenticated through MiLogin for Business.

The system rewards preparation — and penalizes winging it, with a documentation rule that restricts online access for carriers who process transactions without their papers in hand.

Access and the documentation rule

New accounts open through online services (IRP Services → Apply); existing carriers log in via MiLogin for Business (password help: 1-888-767-6424). Any IRP transaction can be processed and paid online around the clock; renewals can also go by mail. The warning Michigan prints in bold: ALL documents must be in your possession before processing online — an undocumented transaction gets your online access restricted, and fees paid for undocumented transactions are not refunded.

Staggered months and the renewal rhythm

Michigan staggers IRP so credentials expire in different months, pegged to when the account opened — an account opened in January expires December 31, one opened in July expires June 30 — always on the last day of the month, with enforcement the first day after. Renewal applications appear in online services (or the mail) 60 days before expiration, with an email alert for online accounts.

And plan on eventually being audited: Michigan is required to audit 3% of renewed accounts per year, comparing trip records against quarterly summaries and renewal-reported distances — the state itself notes most Michigan IRP accounts will eventually be audited.

Michigan’s 2290 windows — the most explicit in the country

Michigan publishes exactly which tax year’s Schedule 1 works when: although the new HVUT period begins July 1, owners have until October 1 before the new period’s 2290 must be shown. From July 1 through September 30, proof from either the last tax year or the current one is accepted; from October 1 through June 30, only the current year.

Acceptable formats: the validated Schedule 1 (photocopy fine, stamp fully legible) or the e-filed Schedule 1 showing the full electronic watermark and the complete payment-received date. No validated copy yet? Michigan takes the 2290 front page plus Schedule 1 plus payment evidence — both sides of the IRS-validated check, an IRS cash receipt (Form 809), or an EFTPS payment confirmation. Vehicles registered within 60 days of purchase are excused entirely.

Frequently asked questions

Can a Secretary of State branch office help with Michigan IRP?⌄
No — Michigan states that branch offices cannot assist with IRP apportioned registrations. Everything runs through the Lansing IRP Unit: online via michigan.gov/irp and MiLogin for Business, by mail for renewals, or by phone at 517-335-6119.
When does my Michigan IRP registration expire?⌄
On the last day of the month determined by when your account opened — Michigan staggers expirations across the year (January openings expire December 31, July openings June 30, and so on), with enforcement starting the first day after and renewal materials arriving 60 days ahead.
Which year’s 2290 does Michigan accept?⌄
From July 1 through September 30: either the prior or the current tax year’s proof. From October 1 through June 30: the current year only. It is one of the few states that publishes the transition window explicitly — and vehicles registered within 60 days of purchase need no proof at all.
Why was my Michigan IRP online access restricted?⌄
Almost certainly a documentation issue: Michigan requires every supporting document to be in your possession before processing a transaction online, restricts access when transactions are processed without them, and does not refund fees paid on undocumented transactions. Gather the title, lease, insurance, and Schedule 1 first, then file.
