My property tax bill came a while ago and I couldn't believe the cost, just about $500. Now that my boat is over a year old I would think that it would be worth significantly less than I paid so I gave the county a call. After a brief discussion with somebody in the marine division of the county assessor's office they reduced the tax bill by more than $100.
Check your tax bill, don't be bashful to give them a call if you think they have your boat's value overstated.
Its not too late. Just file for a lower valuation/dispute on the last payment and if successful they will refund the difference. Go online to find the form. They will call you to settle on a value. I was able to walk the adjuster through lower NADA value over the phone and reduce the tax.
