If you close on a Gilford home this fall, you'll split a tax bill with the seller, and the rate behind it may not be set yet. Gilford mails its second-half property tax bill in late October and bases it on a new rate that the New Hampshire Department of Revenue Administration sets each year. On its real estate tax information page, the town says it "cannot be a party to the proration of taxes at the time of closing," so the split is between buyer and seller alone. The bill you split is also built on an assessment that, for most Gilford properties, sits well below what they sell for. Gilford will close that gap with its next town-wide update, and the town hasn't announced a year for it.
How the fall calendar sets up the proration
Gilford's tax year runs April 1 to March 31, and the town says its bills don't cover any specific part of that year. Here's how 2026 plays out:
- First issue. Mailed May 27, 2026, and due Thursday, July 2, 2026. It equals half of the prior year's total tax and is credited against the final bill.
- Rate setting. DRA dated Gilford's last two rates October 31: 10/31/24 and 10/31/25.
- Second issue. Mailed in late October and generally due around December 1. It covers the full year's tax at the new rate, minus what was billed in May.
- Interest. 8 percent per year on any bill paid after its due date.
So a buyer and seller writing a fall contract may have to prorate before the 2026 rate is public. Gilford's 2026 town meeting packet projected the municipal part of the rate at $4.31 per $1,000, up from $4.03. That was a budget estimate for the town's slice only. School and county taxes made up about two-thirds of the bill in that same packet, and none of them were part of that projection.
The ratio that slipped after 2023
Every year the town compares assessed values to arm's-length sale prices and reports the median result. A home assessed at $190,000 that sells for $200,000 has a ratio of 95 percent. Here is Gilford's recent history, from the assessing agent's sections of the town's 2024 annual report and 2025 annual report:
| Ratio year | Median assessment-to-sales ratio | What happened |
|---|---|---|
| 2022 | 73.6% | Before the update |
| 2023 | 97.7%, preliminary | Town-wide statistical update |
| 2024 | 86.7% | No update |
| 2025 | 83.9%, preliminary | No town-wide update reported |
The 2025 figure is based on sales from October 1, 2024 through September 30, 2025. It's the most recent official measurement. Put simply, a typical Gilford property that sold in that window was assessed at a bit under 84 cents for every dollar it brought.
DRA's own 2025 equalization report uses a different measure, the weighted mean, and puts Gilford at 76.0 percent. A weighted mean gives expensive sales more pull. When it comes in below the median, that's a reasonable sign that the higher-priced sales sold further above their assessments than the typical sale did. That reading is ours, not a finding the state publishes. It does line up with what the town's assessing agent reported about prices.
Where prices moved fastest
The 2024 annual report includes average sale prices for improved properties by category. Compare the 2023 and 2024 calendar years:
- Single family: $646,900 in 2023, $634,800 in 2024
- Mainland waterfront: $2,496,250 in 2023, $3,860,000 in 2024
- Governors Island waterfront: $4,700,000 in 2023, $7,050,000 in 2024
- Condo with waterfront: $869,800 in 2023, $930,000 in 2024
- Boat slips: $169,560 in 2023, $203,500 in 2024
The town warns that averages can mislead when categories aren't evenly represented. A year with a few big waterfront sales can push the number around. Still, the assessing agent's summary points the same way. Waterfront, condominiums, and boat slips saw the largest increases on average, and single-family non-waterfront prices were "starting to level off."
Over the same stretch, the town's total net valuation barely moved. It rose 0.75 percent for 2024 and 0.70 percent for 2025, mostly from inspections, permits, and sales review rather than any market adjustment. Prices climbed fastest in exactly the categories where assessments stood still.
What the gap does to the seller's tax bill
The total rate was $11.25 per $1,000 in 2024 and $11.85 in 2025. The 2025 rate breaks down as town $4.03, county $1.06, local school $5.61, and state school $1.15.
Measured against what a property actually sells for, the effective rate runs lower. At the 2025 median ratio of 83.9 percent, $11.85 works out to roughly $9.94 per $1,000 of sale price. At DRA's 76.0 percent weighted mean, it's closer to $9.01.
Here's an illustration. It's arithmetic, not a forecast. Say a home sells for $800,000 and is assessed right at the 2025 median ratio, about $671,000. At $11.85, its annual bill comes to about $7,950. If that same home were assessed at its full sale price, the bill at the same rate would be about $9,480. The difference of roughly $1,500 a year is what the gap is worth on that one house. A buyer who reads the seller's bill as "the taxes" is reading a number that state law and town practice are both set up to correct.
The update is required. Its timing isn't fixed.
RSA 75:8-a requires every New Hampshire municipality to reappraise all real estate to full and true value at least every fifth year. The town's report adds that DRA requires assessments to fall between 90 and 110 percent of market value at least once in five years. Gilford hasn't tied itself to the bare minimum. It updated town-wide in 2020, 2021, and 2023. In its 2025 report, the town explained why:
"Performing more frequent updates adjusts taxes more incrementally as the market moves as opposed to all at one time."
As of mid-October, the town's Assessing Office page says "No notices at this time." Neither the 2025 annual report nor the town's posted assessing material names a year for the next update.
What the 2023 reset looked like
The last update shows what happens when the gap closes. The Laconia Daily Sun reported that Corcoran Consulting Associates, the town's assessing agents, ran a statistical update using about 325 sales. Total assessed value rose 34.8 percent, from $2.6 billion to $3.5 billion.
The increases weren't even across property types:
| Category | Average 2023 adjustment |
|---|---|
| Single-family homes | up 35% |
| Condominiums | up 38% |
| Boat slips | up 60% |
| Mobile homes | up 84% |
| Vacant land | up 200% |
The town's part of the rate was estimated to drop from $4.14 to $3.46 per $1,000. That estimate didn't cover county or education taxes, which made up about 66 percent of the rate.
A falling rate spreads the same total tax over a bigger base. If your property's assessment rises about as much as the town's, your bill stays roughly where it was. If it rises more, as boat slips and vacant land did in 2023, you carry a bigger share of the total. For a 2026 buyer, the useful question is how far this property's assessment sits below its own sale price compared with the town's median of 83.9 percent.
Reading a fall contract with this in mind
When you're working through a Gilford purchase, here's how we'd handle the numbers:
- Divide the property's current assessment by your contract price. Compare that figure to 83.9 percent.
- Figure the annual tax at $11.85 on both the current assessment and your purchase price. Use the higher one for planning.
- Check whether the 2026 rate has posted before you agree on the proration formula. If it hasn't, decide with the seller how a later true-up will be handled.
- Keep the December due date and the 8 percent interest in mind if the closing falls near it.

A few questions buyers ask
Does Gilford split the tax bill between buyer and seller?
No. The town says proration is an agreement between buyer and seller and that it can't be a party to it.
What if I think my assessment is too high?
New Hampshire's Board of Tax and Land Appeals publishes the state's abatement process and deadlines. According to the board, an abatement application goes to the municipality first, with a March 1 deadline when the final tax notice is mailed by December 31, and an appeal to the BTLA or superior court comes after that. A tax attorney or the town's assessing office can tell you how that applies to your property.
Where can I check the rate once it's set?
DRA posts every town's rate in its yearly municipal tax rate report. Gilford also posts tax bill notices on its real estate tax page.
