West Hartford's 2026 Revaluation Notices:
How to Read Yours, What to Check, and When to Appeal
Quick Answer
- West Hartford's new assessments are set as of October 1, 2026, replacing values based on the town's October 1, 2021 revaluation. Owners receive a notice in November 2026, and the first tax bill based on the new values is due July 1, 2027.
- A higher assessment does not automatically mean a higher tax bill. The town describes the revaluation as revenue neutral, and says the mill rate falls in proportion to growth in the overall grand list if budgets stay the same. The mill rate will not be known until the budget is adopted in spring 2027, so what matters is how your assessment changes compared with the town overall.
- Know the dates: informal reviews in November and December 2026, a second notice in January or February 2027 for owners who attended, Board of Assessment Appeals applications due February 1 to 20, 2027, and Board hearings in March 2027.
- Check the facts the town has on record for your home, compare your value with sales near the assessment date, and ask questions early. The town's revaluation page says there is no disadvantage to appealing.
Every Connecticut town must revalue its properties on a regular cycle, and West Hartford's turn is this year. The notices that arrive in November will show your home's previous assessed value and its new one, and for many owners the new number may differ sharply from the old one, because the last revaluation, effective October 1, 2021, predates years of market movement.
A larger number on a notice is not a tax bill. The tax bill comes from two numbers, your assessment and a mill rate that has not been set yet, and the way those two interact is the part most owners misread. Reading the notice correctly takes a few minutes, and the deadlines are firm.
This guide explains the timeline, what the notice shows, how a higher assessment can leave a bill nearly unchanged, how to check your home's record, and how the informal review and the formal appeal differ. It is informational and is not legal or tax advice.
The Revaluation Timeline
| When | What happens | What you can do |
|---|---|---|
| October 1, 2026 | Assessment date for the new values | Sales near this date matter most when you compare your value |
| November 2026 | Value notices arrive, showing prior and new assessed values | Read the notice, check the property details, and note the review instructions |
| November–December 2026 | Informal reviews with the town's appraisal firm, Vision Government Solutions | Book a meeting and bring your evidence |
| January–February 2027 | A second notice goes to owners who attended an informal review, stating whether the value changed | Decide whether to file a formal appeal |
| February 1–20, 2027 | Board of Assessment Appeals applications are due | File on time if you still disagree with the assessment |
| March 2027 | Board hearings and certification of values | Present your case if you filed |
| Spring 2027 | The town adopts its budget and sets the mill rate | Estimate your bill once the rate is known |
| July 1, 2027 | First tax bill based on the October 1, 2026 grand list is due | Budget for the new amount |

If disagreement remains after the Board hearing, the next step is an appeal to Superior Court under Connecticut General Statutes Section 12-117a.
How Your Assessment Works
West Hartford assesses real estate at 70% of fair market value, and the town defines fair market value as the price agreed between a willing buyer and a willing seller, taking into account the property's permitted uses. A purchase price is not always the fair market value, because a sale can reflect unusual terms, timing or condition.
The tax is the assessed value multiplied by the mill rate, divided by 1,000. The town's online assessment database lists a mill rate of 46.77 for real property on the October 1, 2025 grand list, which is the rate behind current bills. Using that rate, a home with a fair market value of $900,000 has an assessed value of $630,000 and a tax of about $29,465. After the revaluation, both numbers change: the assessment is reset to October 1, 2026 values, and the mill rate is set in spring 2027.
Why a Higher Assessment May Not Mean a Higher Bill
The revaluation is designed to raise assessments to current market levels, not to raise money. The town describes it as revenue neutral: if budgets stay the same, the mill rate falls in proportion to any increase in the overall grand list. The key is relative change. A home whose assessment rises by the same percentage as the town as a whole should see roughly the same bill, a home that rises more can pay more, and a home that rises less can pay less.
The table below shows an illustration only, not a forecast. It assumes the town's total grand list rises 25%, the budget is unchanged, and the mill rate therefore falls from 46.77 to about 37.42, applied to a home currently assessed at $630,000.
| Scenario (illustration only) | New assessment | Mill rate | Annual tax |
|---|---|---|---|
| Today | $630,000 | 46.77 | $29,465 |
| Your home rises 25%, same as the town | $787,500 | 37.42 | $29,465 |
| Your home rises 40%, faster than the town | $882,000 | 37.42 | $33,001 |
| Your home rises 10%, slower than the town | $693,000 | 37.42 | $25,929 |
Hypothetical figures for explanation. Actual assessments, the grand list and the mill rate will differ, and a town budget that changes will change the mill rate as well. Figures rounded.
That is why waiting to see the mill rate is not the same as ignoring the notice. The notice is your only chance in the process to compare your home's value with the neighbors' values and with sales.
How to Check Your Notice
- Check the property facts. Confirm the square footage, number of bedrooms and bathrooms, lot size, age and features the town has on record. The town's online assessment database lets owners review their property data and contact the Assessor's Office about discrepancies, and an error in the record can carry into the value.
- Make sure condition and improvements are accurate. If you renovated, added space or left a feature unfinished, the record should reflect the home as it stands on the assessment date, not an outdated version.
- Compare with sales near October 1, 2026. Look at recent sales of similar homes in your area. The Board of Assessment Appeals says it does not consider sales or appraisals dated after the revaluation date, so evidence near October 1, 2026 carries the most weight.
- Compare your change with your neighbors'. If similar homes nearby were valued very differently from yours, that is worth raising at the informal review.
- Check the ratio. West Hartford assesses at 70% of fair market value, so dividing the new assessed value by 0.70 shows the market value the town is implying for your home.
- Put the dates on your calendar. The informal review window and the February 20 deadline are the two that matter most.
The Informal Review and the Formal Appeal
| Step | Informal review | Board of Assessment Appeals |
|---|---|---|
| When | November–December 2026 | Applications due February 1–20, 2027; hearings in March 2027 |
| Who handles it | The town's appraisal firm, Vision Government Solutions, scheduled online or through the Assessor's Office | The town's Board of Assessment Appeals |
| Best for | Correcting factual errors and discussing how the value was set | Disputing the assessed value when you still disagree |
| What happens next | A second notice in January or February 2027 states whether the value changed | If still unresolved, an appeal to Superior Court under Section 12-117a |
The informal review is the efficient first step, because errors in square footage, condition or features can often be corrected there. The formal appeal is a written filing, and Harris Beach Murtha, a Connecticut law firm, warns that a property owner loses the ability to challenge an assessment if a timely appeal is not filed with the Board. The same firm notes that a court appeal must be filed within two months of the Board's decision, and that for assessments over $1 million, state law requires an appraisal to be filed within 120 days after a court appeal begins. If you expect to appeal, speak with an attorney experienced in Connecticut property tax appeals before the deadlines.
The Board's role is to review assessments. The mill rate is set through the town budget, so an appeal can address the value of your property but not the rate.
If You Are Buying or Selling During the Revaluation
The revaluation affects real estate transactions this winter, because buyers want to know what they will pay and sellers want to explain it.
- Sellers should have the current tax bill and mill rate ready, and tell buyers that new assessments take effect for the July 1, 2027 bill and may change the figure. Our seller timeline covers the other disclosures to prepare.
- Buyers should ask what the current assessment is, remember that the new assessment may differ from the purchase price, and model taxes under more than one outcome. Our property tax guide and bidding-war guide show how to build taxes into an offer.
- Everyone should treat a purchase price as one data point and not an automatic assessment. A purchase price is not always fair market value.
Mistakes to Avoid
- Ignoring the notice. The notice is the start of the only process for correcting a value.
- Waiting for the mill rate. The rate is set in spring 2027, after the Board of Assessment Appeals deadline.
- Missing February 20. A late filing is not accepted, and the right to appeal can be lost.
- Appealing the tax rate. The Board reviews assessed value, not the mill rate.
- Relying on the wrong evidence. Sales and appraisals dated after the revaluation date are not considered.
The Bottom Line
Read your November notice carefully, and judge it relative to the town. A higher assessment is expected after five years, and the town describes the revaluation as revenue neutral, so the question is whether your home rose more than comparable homes.
Use the informal review first, and mark February 20, 2027. Check the property facts, compare sales near October 1, 2026, and speak with an attorney if you expect a formal appeal.

When will West Hartford revaluation notices arrive?
Owners receive value notices in November 2026, showing the previous and new assessed values as of October 1, 2026. Informal reviews follow in November and December 2026, and the first tax bill based on the new values is due July 1, 2027.
Will my taxes go up if my assessment goes up?
Not necessarily. The town describes the revaluation as revenue neutral, and says the mill rate falls in proportion to growth in the overall grand list if budgets stay the same. What matters is whether your assessment rises more or less than the town as a whole, and the mill rate is not known until the budget is adopted in spring 2027.
What is the deadline to appeal a West Hartford assessment?
According to the town's revaluation schedule, Board of Assessment Appeals applications are due February 1 to 20, 2027, with hearings in March 2027. A Connecticut law firm warns that missing the timely filing can forfeit the right to challenge the assessment, so confirm the exact deadline on your notice.
What is the informal review?
It is a meeting with the town's appraisal firm, Vision Government Solutions, held in November and December 2026, where owners can raise factual errors or questions about their value. Owners who attend receive a second notice in January or February 2027 stating whether the value changed.
What evidence helps in questioning an assessment?
Accurate property facts and recent sales of comparable homes near the October 1, 2026 assessment date are the most useful. The town's Board of Assessment Appeals does not consider sales or appraisals dated after the revaluation date. An attorney or appraiser can advise on stronger evidence if you plan a formal appeal.
