Michigan 2018 Auto Insurance Deductible Limits for Homeowners

Deductible Caps for 2018 Michigan Auto Policies

In Michigan, the 2018 auto insurance law capped the deductible for collision and comprehensive coverage at $1,000 for each vehicle. This limit applied whether the policy was purchased through a dealer, a broker, or directly from an insurer. The cap was designed to protect drivers from unexpectedly high out‑of‑pocket costs after an accident.

Impact on Homeowners' Property Tax Deductions

Homeowners can claim a tax deduction for the insurance premiums they pay on their primary residence. However, the deductible amount is not directly tied to the auto insurance deductible cap. Instead, the property tax deduction is calculated from the total annual premium paid for the home, not the vehicles. The $1,000 auto deductible cap does not reduce the amount that can be deducted from property taxes.

How to Calculate Your Deduction

To determine the deductible portion of your homeowners' insurance for tax purposes, follow these steps:

• Gather the annual premium statement from your insurer.
• Subtract any portion paid for additional coverages that are not eligible for deduction (e.g., certain personal liability add‑ons).
• Enter the remaining amount on your Michigan Property Tax Return under the "Homeowners' Insurance Premium" line.

Common Misconceptions

Many homeowners mistakenly believe that a lower auto deductible reduces the deductible portion of their homeowners' insurance. The two are unrelated: the auto deductible cap limits out‑of‑pocket costs for auto claims, while the homeowners' tax deduction depends solely on the premium paid for the house.

State‑Specific Rules and Exceptions

Michigan's 2018 law applied uniformly across all counties. There are no county‑level variations in the auto deductible cap. However, if a homeowner has a multi‑policy bundle that includes auto and home, the premium statements must clearly separate each policy's cost for accurate tax filing.
