If you own a manufactured or mobile home in Indiana, your property tax treatment depends on one question most owners have never been asked directly: is your home assessed as personal property or as real property? The answer changes your assessment date, when your taxes are due, whether you pay in arrears, and what paperwork stands between you and moving or selling the home.
Indiana Code chapter IC 6-1.1-7 governs the whole system, and the DLGF walks assessors through it in its mobile home assessment guidance. Here is what it means for you as the owner.
The two tracks
| Annually assessed (personal property) | Real property | |
|---|---|---|
| Typical situation | Home on rented land — a mobile home community, or land owned by someone else | Home on land you own, typically on a permanent foundation |
| Title status | Certificate of title from the BMV | Affidavit of transfer to real estate recorded with the county recorder |
| Assessed | Every year, as of January 1 | With the land, like any house |
| Taxes due | May 10 and November 10 of the same year as the assessment | Following year (normal arrears billing) |
| Moving/selling | Requires a treasurer's permit showing taxes paid | Sells with the land at closing |
The dividing line is ownership and title, not construction. A "real property mobile home" is one with an affidavit of transfer to real estate recorded by the county recorder — at that point it stops being titled like a vehicle and is assessed as part of the parcel. A home sitting on land the homeowner does not own stays on the personal-property track and is assessed annually under IC 6-1.1-7.
If your home is on the real-property track, your tax life looks like every other Indiana homeowner's: assessed with the land, billed in arrears, spring and fall installments. The rest of this guide focuses on the annually assessed track, where the rules genuinely differ.
The annually assessed calendar: no arrears
Indiana's statewide assessment date is January 1 (IC 6-1.1-2-1.5), and that applies to annually assessed mobile homes too. But here is the twist that surprises owners who previously owned a site-built house: annually assessed mobile home taxes are not billed a year behind.
Under IC 6-1.1-7-7, the owner pays the taxes in two equal semi-annual installments due May 10 and November 10 — in the same year the home was assessed. County treasurers describe the system the same way; see, for example, Sullivan County's annually assessed mobile home page. A home assessed January 1, 2026 generates a bill payable in May and November of 2026.
Practical consequences of same-year billing:
- Your mobile home bill and a regular property bill for the same year cover different assessment years. If you own both (say, a home on the annual track plus a small parcel of land), don't assume the two statements are in sync.
- Whoever owns the home on January 1 is on the hook for that year's assessment. Buying mid-year? Settle up with the seller for the year's taxes at the time of sale, because the county's records point at the January 1 situation.
- Missing a due date carries Indiana's standard delinquency penalty — 5% if paid within 30 days on a parcel with no prior delinquency, 10% otherwise — the same structure covered in our missed-payment guide.
Note
Annually assessed homes don't ride the normal Form 11 cycle the way real property does — but you can still disagree with the value. If your home's assessed value looks high relative to what comparable homes actually sell for, ask your county assessor about the appeal procedure for annually assessed mobile homes rather than assuming the number is final.
Moving or selling: the permit requirement
This is the rule that catches the most people, usually at the worst moment. Under IC 6-1.1-7-10, you need a permit from the county treasurer before you can:
- Move the mobile home from one location to another, or
- Transfer the title to a new owner (including name changes on the title).
The treasurer issues the permit only when the taxes, special assessments, interest, penalties, judgments, and costs due and payable on the home have been paid. No paid-up taxes, no permit — and transport companies and the BMV will ask for it. County treasurers publish the mechanics locally; Porter County's permit page is a representative example.
Two details worth knowing before you plan a move or sale:
- The permit expires 90 days after issuance. If your move or title transfer slips past that window, you're back to the treasurer for a fresh permit.
- Buyers: demand the permit. If you buy a mobile home without a title-transfer permit, you may inherit a delinquency problem you can't clear cheaply — the unpaid taxes follow the home, and you won't get your own permit later until they're resolved.
Warning
Selling a mobile home "on the private market" without the treasurer's permit doesn't make the tax debt disappear — it makes it the next dispute. Sellers can't lawfully transfer title without the permit, and buyers who skip the check are volunteering to fund someone else's back taxes.
Deductions: yes, including the homestead
A persistent myth says mobile home owners on rented land can't claim the homestead deduction. Indiana's homestead statute says otherwise. Under IC 6-1.1-12-37, a mobile home or manufactured home not assessed as real property can qualify as a homestead if you own it and use it as your principal residence — with two wrinkles specific to the annual track:
- You must attach a copy of your title to the home when you file the homestead application with the county auditor.
- The total of all deductions on an annually assessed home may not exceed one-half of its assessed value. On a low assessed value, the deductions compress rather than stack in full.
Beyond the homestead (and the supplemental homestead deduction that rides with it — see the homestead guide for the current amounts and the SEA 1 phase-in), owners should check the complete deductions list for anything else they qualify for — over-65, disabled veteran, and the rest. The SEA 1 homestead credit of 10% of the bill, capped at $300, applies to qualifying homesteads as well; our $300 credit explainer covers the mechanics.
Real-property-track owners simply claim deductions the normal way, on the combined home-and-land parcel.
A quick self-audit for mobile home owners
- Which track are you on? Check whether your home has a BMV title (annual track) or a recorded affidavit of transfer to real estate (real property).
- Is the assessed value plausible? Compare against what similar homes in your community actually sell for.
- Are your deductions on file? Homestead requires an application — it is not automatic — and the title-copy requirement trips up annual-track filers.
- Are you current before you move or sell? Budget for full payment of the year's taxes before you'll see a permit.
- Calendar both due dates. May 10 and November 10, same year as the assessment.
Verify your assessment
Whether your home rides the annual track or sits on your own land, the tax bill is only as fair as the assessed value behind it. Verify your parcel's assessment history, deductions, and taxing district with Property Lookup — and if the value looks inflated against real sales, our appeal guide walks through challenging it.
