Williston's 2027 Budget Season: Why Your Property Tax Bill Answers To Two Governments, Not One

If you're closing on a Williston home this month, ask your agent one question before you sign: whose 2027 budget got baked into your tax proration? Not the sale price. Not the school district's number. The credit or debit on your settlement sheet is a bet on figures that two separate governments haven't finished setting, and they're not working from the same calendar.

That's not a hypothetical. On August 2, 2026, the Williston City Commission approved a preliminary 2027 budget of nearly $200 million, with more than $222 million in projected expenses. On a completely separate legal timetable, Williams County commissioners were still working through their own $168.89 million budget proposal for the same tax year, one that doesn't get a public hearing until September 15. Same parcel. Two clocks.

Two Budgets, Two Legal Deadlines

North Dakota state law treats cities and counties differently when it comes to budget timing, and that difference is doing real work on your tax bill right now. Cities have to approve a preliminary budget by August 10, which is why Williston's commission already had numbers on the table by August 2, with department heads set to start hashing out line items on August 24. Counties operate on a longer leash. They only need a proposed budget publicly available and a hearing and final vote scheduled before October 10, which is how Williams County landed on a September 15 hearing for its 2027 levy and budget.

Here's the part that matters for a buyer: cities can't move their preliminary number upward after it's set, but counties can adjust theirs right up until final approval. That means the city's nearly $200 million figure is close to locked, while the county's $168.89 million proposal, and the $15.25 million levy that funds it, could still shift before mid-September.

The Reserve Drawdown Behind The "Modest" Levy Number

A 3% levy increase sounds restrained next to a budget that's also growing 3%, but the county's own numbers show why that restraint is a choice rather than a coincidence. Williams County projects $100.82 million in revenue against $168.89 million in expenses for 2027, a $68.07 million gap that the levy only partly covers. The rest comes out of reserves, which are projected to fall from $126.25 million at the start of 2027 to $70.7 million by year's end.

That's a county deliberately spending down a large cash cushion instead of pushing the full cost onto property owners this cycle. County Administrator Helen Askim told the Williston Herald that commissioners worked to cap the increase at 3% even though it was legally possible to go higher, and that there was little appetite to do so.

That reserve won't refill itself. A buyer thinking in five-year terms, not just next year's bill, should treat this year's 3% as the floor of a trend, not the ceiling.

The Number That Actually Predicts Your Bill

Here's the figure that should carry more weight than either headline percentage: Williston's median effective property tax rate, the actual tax bill divided by the assessor's market value, runs at 0.85%. North Dakota's state median sits at 1.20%. The national median is 1.02%.

That gap is the real story. A 3% levy increase on a base that's already meaningfully lower than the state and national norm still leaves Williston property owners paying less relative to home value than the typical North Dakota homeowner, let alone the typical American one. For a buyer relocating from a higher-tax state, the levy headlines read as bad news. The effective rate says otherwise.

Location Inside The County Still Moves The Number

County-wide averages flatten a real spread. Williston, Wheelock, and Bonetrail carry the highest assessed property values in Williams County, running 0.788x to 1.1x the county average, while Spring Brook carries the lowest assessed values. On the tax-bill side specifically, Williston, Wheelock, and Buford carry the highest bills, at 0.684x to 1.1x the average, while McGregor carries the lowest tax bill in the county at $229.

Williston itself has the highest median tax bill in the county, at $2,189, against a county-wide average bill of about $2,198 on a median assessed market value near $254,998. That average still hides a wide range: the 25th percentile bill lands around $1,275, the 75th percentile near $2,752, and the 90th percentile as high as $3,488. Two homes at similar price points can carry meaningfully different annual tax obligations depending on which township or city boundary they fall inside. That's a conversation worth having with your agent before you write an offer, not after your first tax bill arrives.

Two Levers That Move Your Bill More Than The Levy Does

Buyers who fixate on the levy percentage often miss two mechanisms that do more to shape an actual bill.

• The Primary Residence Credit. Approved applicants can receive up to a $1,600 credit against their property tax bill, though the exact amount isn't finalized until bills are calculated in December. The Williams County Assessor's Office already mailed this year's approval and denial letters on May 13, 2026, which tells you the application window runs earlier in the year than most new owners expect.
• The assessment appeal window. Notices go out each spring and typically reach mailboxes by mid-April, with a formal appeal deadline that falls around the same time. If you close in the fall and your first spring notice looks off relative to comparable sales, that window, not the December tax bill, is when you have standing to push back.

Neither of these shows up in a levy percentage. Both can change what actually lands on your bill more than a 3% county increase does.

What This Means If You're Closing Before September 15

If your closing date falls before the county's hearing, your title company is prorating taxes using the 2026 levy, because that's the only finalized number available. If the county's final 2027 levy comes in at the proposed 3%, or higher, the gap between what you were credited at closing and what you'll actually owe is small in dollar terms on a typical Williston home, but it's real, and it's worth a specific question to your agent or closing attorney about how the settlement statement handled the estimate. It's a five-minute conversation that prevents a surprised phone call next spring.

For sellers, the same logic cuts the other way. If you're pricing a proration credit to a buyer, using last year's confirmed levy rather than guessing at the pending one keeps the number defensible if a question comes up later.

FAQ

Does the city's approved preliminary budget mean my city tax rate is final for 2027? Not entirely. The preliminary budget locks the ceiling under state law, but department-level detail still has to be worked out through commissioner meetings set to begin August 24, and the city's final levy resolution follows later in the budget cycle.

Will the county's levy definitely land at 3%? The county capped its proposal at 3% and Administrator Helen Askim indicated little appetite among commissioners to go higher, but the number isn't final until the September 15 hearing and vote.

How do I apply for the Primary Residence Credit if I'm buying this year? Applications go through the Williams County Assessor's Office, and this year's approval and denial letters were mailed May 13, 2026, which suggests new owners should plan to apply well before next spring rather than waiting for a tax bill to prompt it.

Two governments, two calendars, and a rate that's genuinely lower than the state around it. That combination is exactly the kind of detail a portal listing won't walk you through, and exactly the kind of question worth asking before you sign anything.
