Do You Need a Lawyer to Appeal Property Taxes?

Usually not. For a home, the first-level appeal (your county board of review, appraisal review board or equivalent) is built so an owner can go in without a lawyer. Rules differ by place, and a few situations are different, so here is what the official sources say and where a lawyer starts to make sense.

We are a research tool, not attorneys or a tax firm, and this is not legal advice. Check your own board's rules.

What official sources say

• Texas. The Comptroller says property owners "may appoint someone to represent them in handling hearings," using Form 50-162. Appointing someone is an option, not a requirement. The same page says that for a court appeal, "you should consult with an attorney." The protest deadline in most cases is May 15 or 30 days after the appraisal district's notice, whichever is later. (Texas Comptroller, protests)
• New York. A New York State tax department legal opinion concludes a non-attorney may represent a taxpayer before the board of assessment review, and that small claims assessment review petitioners need not be represented by an attorney. (NY Dept. of Taxation, opinion of counsel)
• Kentucky. The Claims Commission FAQ answers "Do I have to have an attorney?" with "For most taxpayers, the answer is no." The exception is entities such as corporations, LLCs or trusts. If your home is held in an LLC or trust, check this before you file. (Kentucky Claims Commission FAQ)
• Illinois PTAB. The Property Tax Appeal Board's site notes that filings by an attorney-represented appellant go through its eFiling portal, which tells you attorneys are an option there, not a rule. See our PTAB filing guide. (Illinois PTAB)

We did not find a rule in these sources requiring an individual homeowner to hire counsel for the first-level appeal. Your county may differ, and some require a lawyer for entities or for certain court stages, so confirm on your board's own page.

What a lawyer typically costs

Property tax attorneys often work on contingency. One real example is a published engagement agreement from an Illinois firm (Gardi & Haught, 2020 tax year). Its terms:

• Fee is 30% of the first year's tax savings, due when the board lowers the assessment.
• No reduction, no fee.
• A reduction that holds for the later years of the reassessment cycle is part of the deal, and reductions marked "one year only" are billed at 30% of that year's savings.
• Late invoices accrue 1.5% interest per month after 30 days.
• The client pays for any appraisal the firm needs.

(Gardi & Haught sample contingent fee agreement). Other firms charge different percentages. Get the number in writing and read how it treats later years.

A made-up example. Say a reduction saves you $1,500 on this year's bill. At 30%, the first-year fee is $450, and you keep $1,050. If the same $1,500 repeats the next year at no extra work from you, you keep all of it only if the contract does not bill those years too. Read that clause.

When a lawyer is worth considering

• The property is commercial, multi-unit or high-value, so the savings are large.
• The case has to go to court after the board.
• The home is held by an LLC or trust and your state requires counsel for entities.
• You don't have the time and the potential savings are meaningful.

When doing it yourself works fine

• A single-family home where comparable recent sales are lower than your assessed value.
• Your county has an online filing portal or a simple form.
• You can spend an evening gathering your notice, a few comparable sales and photos of any condition issues.

Our free check shows whether your assessment looks high compared with what we can find, and says plainly when it doesn't. Run the free check. If it looks worth appealing, our $50 Appeal Case prepares your documents. You review, sign and file them yourself. We never file for you or represent you.
