Taxes & Budget
The budget has been reviewed by a third party. THK Associates, a Denver planning, market-research and appraisal firm, reviewed the pro forma line by line and concluded it “provides a sound and reliable fiscal foundation for home-rule incorporation.” THK did not prepare the pro forma, was not asked to advocate for incorporation, and was free to identify overstatements. The review is posted in full.

| Category | Amount and detail |
|---|---|
| Revenue — Other revenue | $855K. Building permit fees ($191K), grants and Conservation Trust Fund ($361K), state-shared revenue including Highway Users Tax Fund, specific ownership tax and Road & Bridge ($171K), municipal fees ($80K — solid waste franchise, municipal court fines and licensing; no utility franchise fee is assumed, and none is in the published household cost), marijuana tax ($53K). |
| Revenue — Use tax | $510K. 2.5% use tax, mostly on vehicles registered in Niwot. |
| Revenue — Property tax | $897K. 4-mill municipal levy. |
| Revenue — Sales tax | $2.32M. 2.5% municipal sales tax. |
| Total revenue | $4.58M |
| Expense — Contingency | $131K. Budgeted contingency of $131K. Not committed to any service. In 2030 budgeted spending exceeds revenue by about $5K, which is drawn from general fund reserves. |
| Expense — Events & downtown | $265K. Events and beautification, downtown improvements. |
| Expense — Administration | $324K. Office space, insurance, IT, finance and audit, planning and zoning services ($55K), codification and legal notices ($16K), materials, elections. Planning and zoning is booked under Service Contracts in the pro forma; it sits here because it is a land-use function rather than a contracted service the town buys wholesale. |
| Expense — Pay & benefits | $468K. Town manager, clerk, deputy clerk, benefits, mayor and council, contract attorney and judge. |
| Expense — Service contracts | $721K. Boulder County Sheriff, contracted building department, public works. |
| Expense — Roads — rebuild reserve | $750K. The share of ongoing road maintenance that accrues toward the next mill-and-overlay and reconstruction cycle rather than paying for work performed in 2030. Held, not spent. Derived from the town road cost model rather than shown as its own line in the pro forma. |
| Expense — Roads — work & debt | $1.93M. Repayment on the 2029 road bond ($1,235K), the road work actually performed during the year — crack sealing and chip or slurry seal, about $535K — and snow removal, street sweeping, signs and striping ($158K). Components are rounded to the nearest $1,000 and may not sum exactly. |
| Total expenses | $4.59M |
Modeled 2030 budget — the first year the full structure is in place, and the tightest year in the projection. Roads, including bond repayment, ongoing maintenance, snow removal, and signs, is 58% of the total.
The two hatched bands are money set aside, not spent — about $881K of the $4.59M budget. The larger one is the roads rebuild reserve. Road maintenance is costed on a lifecycle: every year the town pays for crack sealing and surface seal, and sets aside a share toward the mill-and-overlay and reconstruction that come due decades later. That set-aside is $750K of the $1,285K ongoing maintenance line — the pro forma reports the line whole, so we split it here using the town road cost model that produced it. In the years just after the 2029 rebuild, when no heavy work is due, it genuinely accumulates. The smaller hatched band is $131K of budgeted contingency plus about $11K added to general fund reserves; behind it sits a further $160K of contingency the model budgets but does not expect to spend.
Cumulative general fund reserves reach roughly $2.8M by the end of 2030. The roads reserve sits outside that figure by design, expensed within the roads section rather than accumulated in the general fund, so the town is holding more than the $2.8M alone suggests. Other revenue is building permit fees ($191K), grants and Conservation Trust Fund ($361K), state-shared revenue ($171K), municipal fees ($80K — solid waste franchise, court fines and licensing, with no utility franchise fee assumed), and marijuana tax ($53K). Figures from the Pro Forma Budget v1.8, in nominal dollars. This is a planning model, not an adopted budget.
Who Actually Pays It
The figure above is about what the town collects and what it buys. This one is about who hands it over — the question most people are really asking.
Who pays for the town · Modeled 2030
Residents fund 49%. The other 51% comes from businesses, visitors, and the state. About one dollar in 20 of the whole is money Niwot already pays today — to Boulder County, or at the DMV — redirected to the town rather than added.
- Niwot households49.0%47–54% · $2.25MResidential property tax, plus the household share of the sales and use taxes — and about $250K across building permit fees, municipal fees, specific ownership tax and marijuana tax. The hatched slice is $177K of that: building permit fees and specific ownership tax Niwot households already pay today, to Boulder County and at vehicle registration.
- Niwot businesses29.2%24–31% · $1.34MCommercial property, assessed at 25% against a home’s 6.8%, plus business purchasing delivered in and about $70K of permit and municipal fees. Boulder Tech Center and Monarch Park are 72% of that commercial base — this is not a downtown figure. The hatched slice is $51K of permit fees and specific ownership tax already paid today.
- People from outside Niwot11.0%11–12% · $0.50MVisitors and neighbours spending at Niwot businesses — the estimated figure here.
- State and formula money10.8%$0.50MHighway Users Tax ($116K), county Road & Bridge ($18K), grants and lottery-funded Conservation Trust ($361K). It arrives by formula from the state and county rather than as a charge the town levies — though it is not money nobody here pays: Road & Bridge is a Boulder County mill levy on Niwot property, and the Highway Users Tax is fuel tax Niwot drivers pay at the pump. Incorporation changes who receives it, not who funds it.
| Payer | Share, range and detail |
|---|---|
| Niwot households | 49.0% (47–54%), $2.25M. Residential property tax, plus the household share of the sales and use taxes — and about $250K across building permit fees, municipal fees, specific ownership tax and marijuana tax. The hatched slice is $177K of that: building permit fees and specific ownership tax Niwot households already pay today, to Boulder County and at vehicle registration. |
| Niwot businesses | 29.2% (24–31%), $1.34M. Commercial property, assessed at 25% against a home’s 6.8%, plus business purchasing delivered in and about $70K of permit and municipal fees. Boulder Tech Center and Monarch Park are 72% of that commercial base — this is not a downtown figure. The hatched slice is $51K of permit fees and specific ownership tax already paid today. |
| People from outside Niwot | 11.0% (11–12%), $0.50M. Visitors and neighbours spending at Niwot businesses — the estimated figure here. |
| State and formula money | 10.8% (no material range), $0.50M. Highway Users Tax ($116K), county Road & Bridge ($18K), grants and lottery-funded Conservation Trust ($361K). It arrives by formula from the state and county rather than as a charge the town levies — though it is not money nobody here pays: Road & Bridge is a Boulder County mill levy on Niwot property, and the Highway Users Tax is fuel tax Niwot drivers pay at the pump. Incorporation changes who receives it, not who funds it. |
This answers a different question from the figure above. That one shows what kind of revenue the town collects and what it buys; this one shows who hands it over. The two smallest bands are money no Niwot household pays: visitors spending at Niwot businesses, and state gas-tax sharing, county road money and lottery-funded Conservation Trust proceeds that arrive by formula.
The hatched slices are money already being paid. Building permit fees and specific ownership tax — about $228,000 across the two Niwot bands, one dollar in 20 of the town’s revenue — are paid today already, to Boulder County and at vehicle registration. Incorporation makes the town the recipient rather than adding a charge, so they are drawn as part of what Niwot hands over, which is what the figure asks, but marked as money that is redirected rather than new. The state and formula band is the same in kind: Road & Bridge is a county levy on Niwot property and the Highway Users Tax is fuel tax paid at the pump. Which lines are genuinely new and which are redirected is set out in the household cost methodology.
The business band is mostly not downtown. Niwot’s commercial property sits overwhelmingly in the two business parks inside the proposed boundary. Boulder Tech Center, eight buildings on Dry Creek Parkway, is 55% of the town’s commercial value on its own — more than every other commercial property in Niwot combined. Monarch Park, seven buildings on Monarch Park Place and Horizon Lane, adds 17%. Together they are 72%, against 18% along Second Avenue and 9% around Cottonwood Square. The purchasing side leans the same way: the equipment the model counts as business buying is anchored to $13.1 million of business personal property — an actual value, across both parks. The county’s current roll is higher still, $20.6 million; the model keeps the lower figure. Read this band as the whole commercial town, not the shops on Second Avenue.
The visitor band is the estimated one. It depends on Niwot households being about 28% of the $25 million of taxable sales the downtown improvement district records each year — a figure built from household spending rather than observed at the register. What supports it is the district’s own history: downtown sales rose $6.0 million in real terms between 2019 and 2022, a gain residents cannot have produced on their own, since it would mean every household in Niwot adding $290 a month in local spending for two years. It receded in full by 2025. Niwot’s downtown tracks destination towns like Steamboat Springs and Fredericksburg, Texas, not bedroom communities — while Boulder’s downtown, which depends on commuters, lost half its business in 2020 and never recovered.
Ranges span the plausible values of the one input nobody has published: how much of a comparable town’s delivered-goods base is bought by households rather than businesses. We take it as 48% for general merchandise and 37% for communications and services, and the City of Louisville confirmed on 14 September 2026 that it does not record the split and cannot without auditing each vendor — so the range is the answer, not a margin around the answer. The resident share is not a point estimate: it runs from 47% to 54%, so residents fund about half and, at the top of the range, comfortably more than half. Shares divide the pro forma’s $80 million taxable base; measured against the smaller base our own reconstruction supports, the household share would be about three points higher. Figures from the Pro Forma Budget v1.8, in nominal dollars. A planning model, not an adopted budget.
What Is Actually in the Tax Base
The chart above puts Niwot households at about 49% of the town’s total revenue. Of the narrower thing the sales and use taxes actually fall on, households are about 44%. That share depends entirely on what else is in the base — so we would rather show you than assert it, and we can, because a comparable town reports the breakdown.
See the Louisville report this is built from, industry by industry
The City of Louisville reports the taxable sales of vendors with no physical location in the city. That is its “outside city” category — the same destination-sourced concept a Niwot municipal tax would reach — and the City reports it by industry. Below is that report for January through November 2025, converted to dollars per resident so a town of 20,614 can be compared with a town of 4,305.
| Industry | Per resident | Share | Who buys it |
|---|---|---|---|
| General merchandise | $4,898 | 32.0% | Mixed — e-commerce and delivered retail |
| Communications & utilities | $2,427 | 15.9% | Mixed — telecom, data, cable |
| Services | $2,352 | 15.4% | Mixed — taxable goods sold by service firms |
| Manufacturing | $1,166 | 7.6% | Business inputs |
| Finance & leasing | $964 | 6.3% | Business — leased equipment |
| Building materials | $888 | 5.8% | Contractor materials delivered to job sites |
| Wholesale | $870 | 5.7% | Business to business |
| Furniture | $574 | 3.8% | Household — delivered big-ticket goods |
| Food & beverage | $365 | 2.4% | Household — prepared food and delivery |
| Grocery | $301 | 2.0% | Household — non-exempt items only |
| Apparel | $257 | 1.7% | Household |
| Agriculture | $133 | 0.9% | Business inputs |
| Automotive | $106 | 0.7% | Parts and accessories — not vehicles |
| Total | $15,302 | 100% | Annualized from eleven months |
Shares are computed from the 2025 column. The City’s own printed “% of total” column is calculated off 2024 and reads 29.7% and 17.0% for the first two rows, so do not be surprised by the difference — we recomputed rather than reprint a figure that lags a year. The City’s report is here if you want to check the transcription line by line.
Read the right-hand column. Manufacturing, wholesale, finance and agriculture are unambiguously business purchasing, and they are about a fifth of the category on their own. Communications and utilities is the second-largest line in the entire table — larger than furniture, food, grocery and apparel put together — and it appears in no model of consumer spending anyone has ever built. Add contractor materials and the business half of services, and between 56% and 59% of the base is bought by someone who is not a household.
In Niwot that buyer has an address. The two business parks inside the proposed boundary — Boulder Tech Center on Dry Creek Parkway and Monarch Park on Monarch Park Place — are 15 of the town’s 65 commercial parcels and 72% of its commercial property value, against 18% along Second Avenue. The Tech Center alone is worth more than every other commercial property in Niwot combined. Together the two parks hold about 1,100 jobs, close to 60% of every job inside the proposed boundary (U.S. Census Bureau, LEHD 2023). Manufacturing, wholesale and leased equipment are not abstractions borrowed from Louisville; they are what those parks buy.
That is the whole reconciliation. A town can have a large tax base and a household can have a modest tax bill at the same time, because they are not the same people buying.
Two things the same report settles
The base is durable, not a pandemic artifact. Louisville’s outside-city collections went from $4.94 million in 2020 to $10.92 million in 2025 — more than double in five years, and up 9.5% in the last year alone. In November 2025, vendors outside the city produced $948,699 against $846,948 from businesses physically located in Louisville. Destination-sourced sales are now the larger half of that town’s sales tax, and its steadiest component is the telecom line, which barely moves from year to year.
Vehicles are not counted twice. A fair question to ask of the pro forma is whether motor-vehicle tax sits inside both the sales tax base and the separate use tax line, which would inflate the budget by counting the same money twice. It does not. Louisville reports auto use tax in a column of its own — $1,870,831 in 2025 — entirely outside the $10,915,079 in the table above. Automotive inside the outside-city category runs between 0.7% and 1.2%, which is the signature of parts and accessories rather than cars. In 2020 that line was three dollars.
Is the Estimate Too High?
Two challenges are worth answering directly, because a revenue estimate that is wrong in either direction changes what the town can actually do.
Then is the $55 million remote-sales estimate inflated?
We tested it against a primary source and it holds. The City of Louisville reports its “outside city” taxable base by industry in its monthly Finance Committee packet, and provided that report to us directly. For January through November 2025 the category collected $10,915,079 at a 3.775% rate — an annualized base of about $315 million, or $15,302 per resident. The pro forma had assumed $14,724 for Louisville, so its benchmark was slightly conservative rather than generous. Read the City’s report and check our arithmetic against it.
The simplest check needs no model at all. Colorado publishes every city’s taxable sales from its own tax returns. Louisville’s actual base works out to $28,051 per resident and the Town of Lyons’ to $21,168. The pro forma models Niwot at $18,583 — below both, while Niwot has higher per-capita income than either and more commercial property than Lyons. That is a conservative assumption, and anyone can check it at data.colorado.gov.
Louisville’s category includes business purchasing, so test it on a town with no major hotel, no hospital and no office park. The Town of Lyons publishes its own monthly split between local and non-local businesses — online sellers, out-of-town deliveries, utilities. Across 2025, non-local sales came to $12,382 per resident. We model Niwot at $12,777, with per-capita income 44% higher than Lyons’ and more jobs per resident. Read the Town’s report.
Rebuilding Niwot’s base industry by industry from Louisville’s reported mix points the same way. Several methods put it between $48 million and $67 million against the modeled $55 million, and the low end comes from the one method we can show fails a test: applied to Lyons, it predicts a third less than Lyons actually collects. The methods that reproduce Lyons correctly land at or above the pro forma.
A deliberate floor, avoiding our judgment entirely: take Louisville’s $15,302 per resident, delete manufacturing, wholesale and finance outright, and apply no adjustment for Niwot’s higher incomes. That still gives $12,301 per resident — a $53.0 million base, within 4% of the modeled figure and comfortably inside the 20% permanent shortfall the budget is stress-tested against.
What happens to the budget if the spending estimate is wrong?
The pro forma tests this directly. Sales tax collections would have to fall roughly 20% permanently — and stay there — before general fund reserves would be exhausted at any point through 2040. Every reconstruction we have run sits inside that threshold, and most of them sit above the modeled base rather than below it.
It is also worth separating the two questions. If the revenue estimate is too high, household cost falls with it, because the same purchases drive both. What nobody can argue is that the base is too small for the town and too large for the household at the same time. It is one base with different payers.
How Niwot Compares
Every incorporated municipality around Niwot levies a local sales tax. Niwot’s proposed 2.5% rate is the lowest in the area.
| Municipality | Local Sales Tax | Combined Rate |
|---|---|---|
| Niwot (proposed) | 2.50% | 7.84% |
| Town of Erie | 3.50% | 8.84% |
| City of Longmont | 3.53% | 8.87% |
| Town of Louisville | 3.78% | 9.11% |
| City of Boulder | 3.86% | 9.20% |
| City of Lafayette | 3.87% | 9.21% |
| Town of Lyons | 4.00% | 9.34% |
Combined rate includes Colorado state (2.90%), Boulder County (1.335%), RTD (1.00%), and SCFD (0.10%) taxes, which apply everywhere in Boulder County. Groceries are exempt from local sales tax under Colorado state law. Source: Colorado Department of Revenue, municipal websites. Rates as of January 2026.
What Changes for Niwot
Incorporation does not create taxes from scratch — it shifts authority to local control and captures revenue that currently goes uncollected.
The Case
A sales-tax-led revenue model is a deliberate choice. Niwot’s downtown is a regional destination — events like Rock & Rails, First Friday, and the Honeybee Festival draw visitors from Boulder, Longmont, and beyond. A local sales tax means visitors who use Niwot’s streets, parking, and public spaces contribute to maintaining them. It also gives the town a direct financial incentive to promote downtown vitality: the healthier the commercial district, the stronger the tax base.
The pro forma budget models 14 years of revenue and expenditure projections under conservative assumptions. Revenue comes primarily from the 2.5% sales tax and 4-mill property tax, supplemented by use tax, state-shared revenues, and franchise fees. Groceries are exempt from the local sales tax under Colorado state law.
The budget has been stress-tested through Monte Carlo simulation, modeling thousands of scenarios with varying economic conditions. Reserves remain positive throughout in about 97% of those runs; in the remaining 3% they dip below zero at some point. The road bond is revenue-backed — repaid from sales-tax receipts, not from a new property-tax increase. Debt service is the first claim on that revenue: seehow the bond works.
