The values of property must be up-dated every five years and must reflect market value (as opposed to actual cost or perceived value). Market value is always based on actual comparable sales of similar properties in Canaan or near Canaan.



There are programs created by law to provide property tax credits, exemptions (reduction of the value of taxable property) and deferral of taxes owed. The forms used for these programs can be found at NH Department of Revenue Administration

Form PA 29 is used for credits and exemptions and form PA 30 is used for deferrals.

When applying for property tax credits and exemptions, you will need to understand the limitations that apply for each of these programs and these limits will be filled in by the Town.

Why is my seond bill so much higher than my first bill?




The first tax bill is an estimate based on last year's budget and tax base. The actual rate is not set until November of every year. The Town doesn't receive the amount to be raised by taxes for the County, State and the school until November. Your first bill is usually lower because of that timing. The second bill has to catch up on all of the increases in six months and is therefore twice the increase as the annual tax increase.
