The 90-Day Vehicle Rule: How a New Truck Bought Before the Move Costs You 6%

Idaho's sales and use tax rate is 6%. On a $40,000 vehicle that is $2,400. This is the single most expensive thing a relocating buyer can get wrong, and it turns entirely on a date most people never think about: the day you bought the vehicle, not the day you moved.

What the Exemption Actually Says

The Idaho State Tax Commission's Sales and Use Tax Guide for Vehicle Transactions sets out the New Resident Exemption. New residents owe no tax on personal vehicles brought to Idaho if all three of the following are true: they acquired the vehicle while residing in another state or country; the vehicle was primarily for use outside Idaho, and that use was actual and substantial; and they acquired the vehicle more than 90 days before moving to Idaho. The authority is Idaho Code § 63-3621(k)(1) and IDAPA 35.01.02.107.04. An out-of-state registration or title issued more than 90 days before the move is the proof the Tax Commission names. The Commission's own example: someone who moves to Idaho with a vehicle she has owned for two years does not owe tax.

The Flip Side

Idaho presumes that property bought less than 90 days before moving was purchased for use in Idaho, and it does not qualify. A household that trades in the old car and buys a new one two months before closing on an Idaho house owes 6% on that new vehicle. Buy 90-plus days ahead of the move, or buy after you get here. The six weeks before the move is the worst possible window.

It Is Not Automatic — You File Form ST-102

The exemption only happens if you hand the county a completed Form ST-102, Use Tax Exemption Certificate — New Resident, at the counter when you title and register. The form asks three yes/no questions: are you a new resident of Idaho; did you purchase this property at least 90 days before moving to Idaho; is this your personal property and not an asset of a corporation, partnership, LLC or other separate entity. All three have to be yes. The form covers vehicles, vessels, trailers, campers, RVs and aircraft. Active-duty military use Form ST-102NM instead.

The Traps Inside the Traps

Everyone on the paperwork has to be a new resident. The Tax Commission is explicit: each individual listed on the purchase, title and registration documents must be a new Idaho resident. Putting an existing Idaho resident on the title kills the exemption. It has to be personal property. A vehicle titled to an LLC, corporation or partnership does not qualify — a sole proprietorship or grantor trust does. Coming from a state with no sales tax does not exempt you from the paperwork. New residents from Oregon, Montana, Alaska, Delaware and New Hampshire still have to file ST-102 to claim it. Foreign taxes get no credit. Idaho does not credit tax paid to another country, though the 90-day exemption itself does apply to a citizen of another country.

If You Do Not Qualify

Idaho gives reciprocity credit for general sales tax actually paid to another state. If what you paid elsewhere was less than 6%, you owe Idaho the difference. If it was equal to or more than 6%, you owe Idaho nothing. The Tax Commission's own worked examples: someone who paid 5.3% elsewhere on a $20,000 vehicle owes Idaho another $140; someone who paid Washington's 8.9% combined rate on the same vehicle owes Idaho nothing. The Commission also warns that a sales agreement showing an out-of-state dealer collected tax does not by itself prove the tax was collected for that state — keep proof of actual payment.

Rural Internet in North Idaho: What to Verify Before You Write the Offer

If you are moving from a city, this is the part of North Idaho that most often surprises people after closing instead of before. In Coeur d'Alene, Post Falls, Hayden and Rathdrum you generally have real choices, often two or three wired providers including fiber. Outside those service footprints the picture changes fast. Large parts of Kootenai, Bonner, Benewah and Shoshone counties have no wired broadband at all. On many rural parcels the only options are fixed wireless, if you have line of sight to a tower, or satellite.

Who Actually Serves Where

TDS Telecom lists six Panhandle communities: Coeur d'Alene, Dalton Gardens, Hayden, Hayden Lake, Post Falls and Rathdrum. Nothing outside those towns — and inside them, fiber versus legacy DSL varies block by block, which TDS's own terms acknowledge. Ziply Fiber has the widest small-town footprint in the region, because it is the former Frontier Northwest network: Coeur d'Alene, Post Falls, Hayden, Rathdrum, Spirit Lake, Bayview, Blanchard, Harrison, Priest River, Sandpoint, Bonners Ferry, St. Maries, Kellogg, Osburn, Pinehurst, Wallace and Mullan. In much of the Silver Valley and around Priest River, Ziply is the only fiber. Spectrum lists Coeur d'Alene, Post Falls, Hayden, Rathdrum, Athol and Bayview — strong in the urban core, thins out quickly. Intermax Networks, a local ISP with offices in Coeur d'Alene, St. Maries and Sandpoint, runs fiber and fixed wireless and covers pockets of rural Kootenai, Benewah and Bonner County that the national carriers skip; fixed wireless needs line of sight to a tower and they will check the address for you. Starlink is the honest answer for a lot of rural parcels and it works — self-install, no local technician, and no published customer service phone number, because everything runs through your online account. The practical limiter here is not the sky, it is the trees. Heavy tree cover is extremely common on North Idaho acreage.

What to Actually Do

Call two providers with the full street address and house number, before you close, and get an answer tied to that address rather than to the town. Coverage maps are drawn at a resolution that does not resolve individual driveways. If the answer is fixed wireless, ask specifically whether they have line of sight from your parcel to a tower — that is a yes-or-no question they can answer. If the answer is satellite, walk the property and look up: dense conifer canopy over the house is the thing that turns a working plan into a non-working one.

Why This Belongs in the Offer, Not the Move

If anyone in the household works from home, internet is not an amenity on this side of the county line — it is a functional requirement with a binary answer, and the answer is attached to the parcel, not the price. It is far cheaper to learn it during due diligence than during your first week of meetings.

The Utility, Septic and Well Questions to Ask Before You Close

In Kootenai County, water and sewer are frequently not provided by the city whose name is on the mailing address. There are dozens of independent water associations, irrigation districts and sewer districts. A Hayden address can be billed by the City of Hayden for sewer, a private association for water, and a separate hauler for garbage. Three bills, three organizations, none of which the listing mentions. The single most useful question you can ask a seller is: who bills you?

Utilities, in Order

Power. Which utility serves the parcel is set by where the house sits, not by the town it mails to. Two houses a mile apart can be on different systems. Avista (800) 227-9187, Kootenai Electric Cooperative (208) 765-1200, Northern Lights (208) 263-5141, Inland Power (509) 747-7151. Gas. Avista is the only natural gas utility in the Panhandle, so there is nothing to shop — the only question is whether a main reaches your street. Being inside city limits guarantees nothing; plenty of homes on the edges of Hayden, Rathdrum and Post Falls are on propane. Check the specific address on Avista's start-service page. Water and sewer. Hayden bills sewer only and provides no water. Dalton Gardens has no city water and no residential city sewer at all — every home there is on a well or an association and a private septic system. Post Falls has water districts serving addresses inside city limits, so use the city's provider look-up. Garbage. In Coeur d'Alene and Post Falls it is on the city bill automatically. Everywhere else you open your own account.

The Septic Record, and Its Date

Idaho requires a permit for every subsurface sewage disposal system, and Panhandle Health District holds the records. Pull the record before closing, not after. PHD's public septic record search is online, but the district's own caveat is that the index is current only as of May 2022 — so if the system was permitted, repaired or replaced after that, the online search will not show it and you need to call. Kootenai County septic permits: (208) 415-5220. Environmental Health runs 8 a.m. to 4:30 p.m. at 8500 N. Atlas Rd in Hayden; main line (800) 878-2364. If you are adding a bedroom, building, or replacing a failed drainfield, this is the same office.

The Well, and What "Exempt" Means

A true domestic well does not need a state water-right permit under Idaho Code § 42-227(1). But "domestic" has hard numeric limits in § 42-111: water for homes, livestock and related uses including irrigation of up to one-half acre, if total use does not exceed 13,000 gallons per day, or any other use not exceeding 2.8 acre-feet per year. Mobile home parks, RV parks, apartments, condominiums and most subdivisions are excluded unless they fit that 2.8 acre-foot ceiling. In-home use expressly does not include irrigating lawns, gardens, landscaping or pastures. Both sections were amended in 2025 and again in 2026, and there is a new wrinkle: for subdivision applications filed on or after July 1, 2025, in any area where the Department of Water Resources has issued a moratorium on new water rights or designated a critical ground water area or ground water management area, new domestic diversions other than in-home use or livestock watering now do require a permit. If the property has a well, or irrigation beyond a small yard, check with IDWR before you are in contract. Well drillers must be licensed under § 42-238, and domestic wells are subject to inspection by IDWR and DEQ.

Two More, If They Apply

Acreage: find out whether the parcel is open range or inside a herd district. It is decided parcel by parcel and the county is who knows — Kootenai County Community Development, (208) 446-1070. Silver Valley: if you are buying in Kellogg, Wallace, Osburn, Pinehurst, Smelterville, Wardner, Mullan, Kingston or along the Coeur d'Alene River corridor, the Institutional Controls Program applies to the property. Protective soil barriers were placed over historic mining contamination, homeowners maintain them, and any excavation — a fence post, a garden bed, a foundation, a new driveway — requires a free ICP permit first. Call (208) 783-0707 before a shovel goes in the ground.
