How Much Does a Property Tax Appeal Cost?

Reputable contingency firms have no hidden fees, but the details vary by provider so it's worth asking. At EPTA, there are no filing fees, research costs, or administrative charges passed to the client — the contingency percentage covers everything from the initial review through negotiation and tribunal representation, and even appraisal costs on cases that require one. Always ask for the full fee structure in writing before signing, and look specifically for language around filing fees, expert witness costs, multi-year engagements, and automatic renewals. Our guide on hiring a property tax consultant walks through exactly what a clean engagement agreement should look like.

In many cases, your property tax consultant handles the valuation analysis as part of the contingency engagement — no separate appraisal needed. For complex cases that go to tribunal, a formal MAI appraisal may strengthen your case. At EPTA, we cover appraisal costs when needed and only bill the contingency fee if we win. See our evidence guide for more on what's required.

With a contingency fee arrangement, no professional fee. If the appeal doesn't produce a reduction in your assessment or tax bill, you owe no fee beyond the modest filing retainer you paid up front — and that is the core advantage of the contingency model, because the large, variable cost sits with the firm rather than with you. This is also why experienced firms are selective: they only take on cases they genuinely believe will succeed, which means a professional accepting your case is itself a signal that a reduction is likely. You can learn more about typical outcomes in our appeal success rate guide, and check the timeline guide to see how long an appeal typically takes from filing to decision.

It depends on the fee structure. With contingency fees, even modest savings are worth pursuing because you have no downside risk. A $10,000 annual savings with a 30% contingency fee still puts $7,000 back in your pocket the first year — and the full $10,000 in every year after. Our DIY vs professional comparison walks through the break-even math on small-dollar cases, and our free review can help you estimate whether an appeal makes financial sense.

For most commercial properties, the return on investment is substantial. The average commercial appeal produces $20,000 to $100,000+ in annual savings, while the one-time contingency fee is a fraction of that. In states like Michigan and Ohio, a successful appeal typically reduces your assessment for multiple years, so the savings compound while the fee is paid only once.
