Contingency Fees in Property Tax Consulting: Defining Savings and Staying Compliant

How a contingency engagement is priced

A contingency agreement sets a percentage of the tax savings produced by the appeal, payable after the reduction is final. If there is no reduction, there is no fee. Most agreements cover one tax year at a time and renew annually, and many add a minimum fee per parcel or a flat filing charge so small parcels still cover their cost.

Owners like the structure because it caps their downside, and it lets them appeal across a whole portfolio instead of picking the three most obvious parcels. Consultants like it because a strong practice can earn more on a large reduction than hourly billing would ever allow. The tension is that the consultant carries the cost of every losing appeal, which pushes small or marginal parcels to the bottom of the queue. That is a labor problem more than a pricing problem, and we come back to it below.

Define realized savings before the appeal, not after

Almost every fee dispute traces back to an agreement that said "savings" without saying from what, at which rate, and for how long. Write the definition into the engagement letter and use the same definition in the invoice.

• Starting value: the value on the original notice for the year under appeal, not the prior year's value. A reduction the assessor made on its own before any filing is usually excluded.
• Ending value: the final value after the board decision, settlement, or further appeal, with any later court result triggering a revised invoice.
• Tax rate: the final adopted combined rate for that tax year, applied to the reduction in taxable value, with the assessment ratio applied where the state assesses at a fraction of market value.
• Exemptions, abatements and caps: savings attributable to an exemption, an abatement, or a statutory cap are carved out unless the agreement covers that work.
• Multi-year effect: whether a reduction that carries into later years of a reassessment cycle is billed once, every year, or at a lower rate in later years.
• Payment trigger: when the reduction is final, when the corrected bill issues, or when the refund is received for taxes already paid.
• Tenant recoveries: whether the fee is calculated on gross savings even though NNN tenants receive part of the benefit through lower reimbursements.

A worked invoice

Cypress Ridge Apartments is a 280-unit Texas multifamily property. The appraisal district's notice value was $41,500,000. After an informal meeting and an ARB hearing on market value and unequal appraisal, the final value was $36,800,000. The combined tax rate for the year was 2.15%, and the engagement priced at 22% of first-year realized savings.

Notice the multi-year clause. Texas appraises every year, so this agreement bills one year at a time. In a jurisdiction where a reduction carries through a multi-year cycle, the same reduction may be worth two or three years of savings, and an agreement silent on the point invites a dispute in year two.

Realized savings = (Notice value - Final value) x Assessment ratio x Final tax rate

The rules that shape contingency work

Contingency consulting is legal in most states, but who may do the work, and in which forum, varies. Get this wrong and the fee may be the smaller problem.

• Texas: anyone who performs property tax consulting for compensation must register with the Texas Department of Licensing and Regulation under Occupations Code chapter 1152. A registrant may not solicit an assignment by assuring a specific outcome, and TDLR rules (16 TAC §66.70(b)) require the department's regulatory notice on written contracts. The owner appoints the agent on Comptroller Form 50-162, Appointment of Agent for Property Tax Matters.
• Illinois: at the Property Tax Appeal Board, 86 Ill. Adm. Code 1910.70 provides that corporations, LLCs, partnerships and similar entities must be represented by an Illinois-licensed attorney. Tax representatives, consultants and appraisers may testify and help prepare the case but may not appear in a representative capacity.
• California: an agent other than a California attorney retained by the owner must file the owner's written authorization with each Assessment Appeals Board application.
• Appraisers: USPAP's Ethics Rule bars an appraiser from accepting an assignment, or a compensation arrangement, that is contingent on the value opinion or a stipulated result. A consultant paid on contingency should not sign the appraisal; an independent appraiser engaged on a flat fee should.

Why the economics change with faster evidence

Consultants spend 12 to 25 billable hours per parcel building evidence by hand (IPT Practice Survey). At that rate, a contingency practice has to triage hard. A parcel with $8,000 of potential savings and a 22% fee earns $1,760 if it wins, which does not cover a day of senior time once losing appeals are counted. So the practice files the large, obvious cases and lets the rest go, and owners with mid-sized parcels quietly overpay.

Cut preparation time and that threshold drops. ATALI ELECTRIC customers have reduced evidence preparation from 16 hours to 20 minutes per parcel, and first-round win rates of 58% to 79%. A consultant on Firm Scale ($17,988 a year for up to 150 appeals) carries a software cost of about $120 per appeal at full use, which makes the $8,000 parcel worth filing. The Contingency & Client Billing module records the starting value, final value, tax rate and fee terms for each parcel and produces the invoice from the same numbers the engagement letter defined.

Choosing the right structure

Contingency is not the right answer for every engagement. Flat fees per parcel suit owners who appeal the same buildings every year and want predictable cost. Hourly billing fits litigation and complex valuation disputes where the work is open-ended. Hybrid agreements, a modest flat fee plus a reduced contingency share, suit portfolios where the owner wants every parcel reviewed and the consultant needs its cost covered on the ones that do not produce a reduction.

For owners who want no upfront cost and no internal workload, ATALI ELECTRIC's Contingency Success Hybrid works through a managed partner network at $0 upfront plus 20% to 25% of first-year realized savings. Partners file and present the appeals; ATALI ELECTRIC provides the evidence and the savings accounting.
