Your Michigan premium charged you for 12 months in both states during your first snowbird year. Here's how to document your Florida months and recover what you overpaid.
Why Your First-Year Premium Charged You for Two States Simultaneously
Your Michigan insurer billed you for 12 months of Michigan coverage at Michigan rates during your first snowbird year, even though you spent November through March in Cape Coral. That's standard practice. Carriers charge the higher-risk state's premium upfront, then reconcile after you prove where you actually drove.
Michigan premiums run $140–$220/mo for liability and comprehensive on a paid-off sedan. Florida premiums for the same coverage run $95–$150/mo in Lee County. If you spent 4 months in Florida, you paid Michigan rates for those 4 months — an overpayment of $180–$280 that won't be refunded unless you request reconciliation with documentation.
Most carriers require you to initiate this process. They will not automatically prorate your premium based on your Florida address appearing mid-policy. You paid for Michigan no-fault Personal Injury Protection coverage during months you weren't driving in Michigan. That's the gap this reconciliation closes.
What Documentation Triggers the Reconciliation Credit
Carriers accept three forms of proof for time spent in Florida: utility bills showing consecutive monthly service at your Cape Coral address, credit card statements with Florida merchant transactions spanning the winter months, or mobile phone location data if your carrier offers that option. The utility bill is the cleanest — 4 consecutive monthly electric or water bills with your Florida address and service dates covering November through March.
You need documentation for both states. Michigan proof matters as much as Florida proof. Your Michigan utility bills should show reduced usage during your away months, and your return should be visible in April or May usage increases. Carriers look for the gap pattern, not just Florida presence.
Submit reconciliation requests within 60 days of your policy renewal date. Most carriers allow retroactive reconciliation for one policy year. If you're on a 12-month policy that renews in July and you wintered in Florida from November to March, submit documentation in July or August. Missing this window means the overpayment becomes final.

How Carriers Calculate the Prorated Refund
The refund is the difference between what you paid at Michigan rates and what you would have paid at Florida rates for the months you were in Lee County. If your Michigan premium is $180/mo and the Florida equivalent is $120/mo, the monthly difference is $60. Four months in Florida equals a $240 credit.
Some carriers issue the credit as a check. Others apply it to your next policy term as a premium reduction. If your renewal is imminent, request the check — a premium credit on a policy you're about to cancel or reprice doesn't help you.
Carriers will not prorate if you maintained Michigan registration and only added a Florida mailing address. The reconciliation requires proof you were physically present and driving in Florida, not just receiving mail there. If you registered your vehicle in Florida mid-year, that registration date becomes your proration trigger, and documentation requirements change.
What Happens If You Registered in Florida During Year One
Registering your vehicle in Florida mid-policy forces a policy rewrite, not a reconciliation. Michigan coverage ends the day Florida registration begins. Your Michigan insurer will refund the unused portion of your Michigan premium from the registration date forward, and you'll need a new Florida policy starting that same day.
Florida requires insurance before registration. You cannot register in Lee County without proof of Florida liability coverage meeting state minimums: $10,000 property damage and $10,000 personal injury protection. If you registered in Florida in January, your Michigan policy should have been canceled in January, and you should have been on a Florida policy from that date forward.
If you registered in Florida but your Michigan insurer kept charging you, contact them immediately. That's not a reconciliation situation — that's a billing error. You were charged for Michigan coverage on a vehicle no longer registered in Michigan. Request a full refund for premiums paid after your Florida registration date and provide the Florida registration certificate as proof.
When Two-State Registration Makes Reconciliation Impossible
Some snowbirds keep Michigan registration and add Florida registration on the same vehicle. Michigan allows this if the vehicle is primarily garaged in Michigan. Florida allows this if you meet residency requirements for a second home. Carriers do not allow this for reconciliation purposes.
If you hold active registration in both states simultaneously, your insurer will charge the higher-risk state's rate for the full 12 months. No proration applies. The policy is priced for Michigan exposure because Michigan registration signals Michigan garaging, regardless of where you physically drive.
The only exception: if you register a second vehicle in Florida and maintain your Michigan vehicle's Michigan-only registration, you can reconcile the Michigan vehicle's premium based on months it sat unused in Michigan. But that requires proof the Michigan vehicle was not driven during your Florida months, which is difficult to document unless you also have mileage records or garage storage receipts.
How to Structure Year Two to Avoid This Entirely
Before your second snowbird year, ask your Michigan insurer if they offer seasonal or laid-up coverage for the months you're in Florida. Some carriers allow you to drop collision and comprehensive to storage-only coverage while you're away, reducing your Michigan premium to $30–$50/mo for those months instead of $180/mo.
If you're registering in Florida for year two, cancel your Michigan policy the day before Florida registration and start a Florida policy the same day. Do not overlap. Overlapping policies do not give you double coverage — they give you two premiums and confusion about which insurer handles a claim if one occurs during the overlap period.
If you're keeping Michigan registration and staying on a Michigan policy, set a calendar reminder 45 days before renewal to submit your year-one reconciliation documentation. Carriers process these requests in 15–30 days. Submitting early ensures the credit posts before renewal.
