The Town of Alton has just completed a 2017 town wide update. All assessments are preliminary and anyone whose assessment has gone up more then $7,000 will receive a letter from the Alton assessors office showing the new and old assessment. At that time anyone wishing to have their assessment reviewed will have the opportunity to do so by appointment only. Do not use the 2016 tax rate to figure your taxes. By doing so it would be an incorrect amount. The new tax rate will be available sometime in October 2017 if not sooner.
