You do not need a lawyer to reduce your property taxes, or to fight increases. Talk to your assessors office about the process and it is something you can do. There are different methods of appealing based on the why your assessment is changing, ie a reassessment or equalization.

Here when it is a reassessment there is the option of talking to the assessor and having them do an informal assessment, basically coming out and walking around the property and giving you a number. You can either agree with the number or disagree. If you agree with the new number you simply sign off and its done. If you disagree you can still do a formal written protest to the board of review.

If the increase is a result of equalization, your only option is to submit a formal written protest.

When talking to the assessor, or in your written protest tell why your taxes should not be increased. For example one time I argued that my taxes were being increased twice in two years while other houses in the area were not. Another time i protested that the increase was greater than what other houses of similar age, size, and design were selling for in my area.
