A Missouri credit almost nobody is writing about

This is a cost page, so here is a cost item that belongs on it and that almost every roofing site in this market has missed. It is not a discount, it is not something a contractor can offer you, and it has nothing to do with what a roof is priced at. It is a provision of the Missouri Revised Statutes.

What the statute says

Section 135.445 of the Missouri Revised Statutes authorises a tax credit for a homestead insurance deductible incurred during calendar year 2025. The essential terms, as written:

Why it belongs on a page about roofing cost

Because for a great many households in this metro, the largest deductible they incurred in 2025 was on a storm claim, and a large share of those storm claims were roofs. The 2025 season in Missouri was not an ordinary one. The Missouri Department of Commerce and Insurance recorded two hundred and fifty three thousand two hundred and forty one catastrophic claims from that season with more than two point nine billion dollars paid, roughly eighty three percent of it residential.

The single event most people in St. Louis remember is the tornado of 16 May 2025. The National Weather Service rated it EF3 at one hundred and fifty two miles per hour. It began near Clayton at 2:41 in the afternoon and tracked twenty two point six miles, and at its widest it was one point eight miles across, which is the widest this region has recorded in a series that begins in 1950. Five people were killed. The damage figure of one point six billion dollars comes from the National Centers for Environmental Information rather than from the weather service. The federal declaration that followed, DR-4877-MO, covered St. Louis City and County and produced nine thousand four hundred and twenty seven individual assistance approvals, fifty eight point one three million dollars in individual and household programme money and one hundred and five point zero one million in public assistance.

If your household was inside any of that, you incurred a deductible in 2025, and this statute exists.

The date is the point

The statute authorises no new credits after 15 October 2026. That is not a filing deadline in the ordinary sense and it is not something anyone can extend for you, so the practical advice is to establish your position early rather than late. What you will need is evidence of the deductible you actually incurred, which generally means your carrier's settlement documentation showing the amount withheld.

Where to check it yourself

Do not take this page's word for any of it. The statute is published at the Missouri Revisor of Statutes and it is short enough to read in a couple of minutes. Forms and eligibility are handled by the Missouri Department of Revenue. If your return is at all complicated, or if the transferability provision is interesting to you, that is a conversation for a tax professional rather than for a roofing site.

What this page is for is simply making sure you know it exists. It is real, it is sourced, it expires, and in a metro that took the 2025 season this metro took, a great many people who are entitled to it have never heard of it.

The rest of the cost picture

Everything else on this site is about the number itself: how the roof is measured, what slope does to it, the one line that cannot be known in advance and how to read the document it all lands on. A tax credit does not change any of that arithmetic. It changes what the season cost your household, which is a different question and a fair one to ask while you are already thinking about roofs.
