Montana Real Estate Transfer Tax Calculator

Montana imposes no real estate transfer tax at the state or county level, one of a group of interior Western and Mountain states, alongside neighboring Idaho and Wyoming, that has never enacted one. A Montana sale computes to $0.00 in transfer tax at any price, whether the property is a Bozeman starter home or a large ranch parcel in the eastern part of the state.

Montana pairs its lack of a transfer tax with the absence of a state sales tax as well, two revenue sources many states rely on that Montana's tax structure simply omits; the state instead leans more heavily on property and income tax. County clerk and recorder offices still charge flat fees to file a deed, and those fees, along with title insurance and any negotiated commission, remain separate from the $0 transfer tax result shown here.

Montana has no real estate transfer tax and no local authority to create one.

The engine reads Montana's hasTransferTax: false flag and returns zero at any sale price, with net proceeds equal to the full price entered. There is no bracket to evaluate and no minimum threshold. Montana does require a Realty Transfer Certificate at recording, but that is a disclosure document rather than a tax return, and nothing on it scales with the price.

Montana's engine path is a lookup, so these are the operations rather than an invented multiplication.

Step 1 -- The consideration. Contract sale price = $380,000

Step 2 -- The rate-table lookup. Montana's entry returns hasTransferTax: false, and no rate is applied.

Step 3 -- Transfer tax due. $0.00

Step 4 -- Net proceeds. $380,000.00 - $0.00 = $380,000.00

Step 5 -- The effective rate. $0.00 / $380,000 = 0.000%

Step 6 -- The luxury scenario, $1,500,000. Price makes no difference to the lookup: $0.00 due, $1,500,000.00 net, 0.000% effective.

The zero at Step 6 is where Montana's rule turns into real money. Bozeman, Whitefish and the Flathead and Gallatin valleys have carried median prices well into seven figures, and a state with a mansion tier would collect heavily there: the same $1,500,000 sale would trigger $15,000 in mansion tax alone in New York on top of the base levy. Montana has no such tier and no base levy either. What Montana does require is a Realty Transfer Certificate filed with the Department of Revenue at recording, disclosing the sale price for assessment purposes. It is a disclosure obligation with no tax attached, and it is easy to mistake for one because the form arrives in the same envelope as everything that does cost money.

Montana's entry in the transfer tax table is flagged as having no transfer tax, so the function returns before any rate or bracket is read. Every figure below comes from running the calculator rather than from reasoning about the statute.

Each additional $100,000 of sale price costs $0.00. That is the marginal figure at every price the input accepts, in both directions.

The sweep, at three points. A $380,000 sale returns $0.00 of tax and $380,000.00 of net proceeds. A $1,500,000 sale returns $0.00 and $1,500,000.00. The net proceeds output is a copy of the sale price at every price, which is the arithmetic signature of a state with no schedule at all rather than one with a very high exemption.

The reverse question has no answer, and that is the finding. There is no sale price within the input's range at which a Montana transfer tax begins. Sellers in bracket states ask how far below a threshold they can price a deal; in Montana there is no threshold to price against.

The mansion tax output is structural, not conditional. The "Mansion Tax / High-Value Surcharge" field exists because several states in this family impose a cliff at $1,000,000. Montana has none, so the field reads $0.00 at $999,999, at $1,000,000 and at $1,500,000. On the New Jersey page the same field is where a seven-figure sale gets expensive.

What the $0.00 is worth, in figures from the sibling calculators. The identical $380,000 sale costs $855.00 in Nebraska, $1,938.00 in Nevada and $5,700.00 in New Hampshire. On a $1,500,000 sale those become $3,375.00, $7,650.00 and $22,500.00. Those differences, rather than the $0.00 itself, are what a seller comparing markets is actually looking at.

What the zero does not cover. County recording fees, clerk charges and the documentary handling costs that appear on a Montana closing statement are real, are not transfer taxes, and are not computed anywhere on this page.

• County recording and clerk fees are not computed. They are not transfer taxes and no input on this page reaches them.
• The mansion tax output is always $0.00 for Montana, because the state entry carries no high-value cliff.

• The Realty Transfer Certificate (Form RTC). Montana requires most deed transfers to be accompanied by this disclosure form reporting the sale price to the Department of Revenue, but it is an assessment tool, not a tax, and carries no fee tied to the sale price.
• County recording fees. Montana county clerk and recorder offices charge modest, flat per-document recording fees that apply regardless of sale price; these are unrelated to the transfer tax question.
• Property tax reappraisal. A sale can prompt Montana's Department of Revenue to update its valuation of the property for future property tax purposes, using the RTC data, which is a separate and ongoing cost, not a one-time transfer tax.
• Title insurance and closing costs, which are set by the private market rather than by the absence of a transfer tax.

• Mistaking the Realty Transfer Certificate for a tax filing. It is a mandatory disclosure form used for property valuation, and while failing to file it can create title and closing complications, it does not itself impose a transfer tax.
• Assuming a nearby state's transfer tax applies. Buyers or sellers relocating between Montana and Washington, which has a significant bracketed real estate excise tax, should not assume the cost structure is comparable; it is not.
• Overlooking recording fees. These are real, if modest, and are distinct from the (nonexistent) transfer tax.
• Assuming no transfer tax means no property-price disclosure to the state. Montana still tracks sale prices through the RTC for assessment purposes even without taxing the transfer itself.
