First-year savings usually exceed the consultant’s entire fee at this tier
The property tax appeal industry is dominated by mass-market services designed for $300K–$750K homes. Flat-fee software that generates an evidence packet for $49 works well at that tier. For a $5M–20M luxury property, the evidence is more complex, the comparables are thinner, the assessor’s model is more systematically wrong, and the dollar amounts justify professional representation. The question is not whether to hire someone at this tier. It is what kind of professional to hire and when.

The Three Professional Options
Option 1: Property Tax Consultant (Full-Service)
A consultant handles the entire appeal on your behalf: pulls the property record, gathers comparables, files the appeal, attends the informal review and formal hearing, and negotiates the reduction. Most work on contingency — 25–50% of the first year’s savings. If they don’t reduce your taxes, you pay nothing. For a $10M property where a successful appeal saves $15,000 per year, the consultant earns $3,750–7,500 in year 1 and you keep 100% in every subsequent year. The best luxury-tier consultants have access to off-market comparable data and specific experience with your local review board. Generalist firms that handle thousands of mass-market appeals simultaneously often underperform at the luxury tier.
Option 2: Property Tax Attorney
An attorney is appropriate for large-dollar disputes, state-level appeals, and judicial proceedings. For informal reviews and board hearings, a consultant is usually sufficient. For a dispute where the assessor is defending a $20M value on a property you believe is worth $14M, with $60,000+ in annual tax at stake, an attorney who specializes in property tax litigation provides the advocacy and procedural expertise that a consultant may not. Fees are typically hourly or contingency depending on the firm and the state.
Option 3: Independent Appraiser
Not a representative, but a key expert witness. A certified residential or luxury property appraiser produces a formal opinion of value that carries significant weight with review boards because it is professional, certified, and defensible. An appraiser is typically engaged by the consultant or attorney as part of the appeal package, but can be hired directly. For a $5M+ luxury appeal, a professional appraisal at $1,500–3,500 is almost always worth the cost.
How to Evaluate a Property Tax Consultant at the Luxury Tier
| Evaluation Criterion | What to Ask | Red Flag |
|---|---|---|
| Luxury market experience | What is the highest-value property you have successfully appealed in my market? | Cannot name specific high-value cases |
| Local board relationships | How many hearings have you attended at my county’s ARB or review board? | Primarily files by mail; limited hearing experience |
| Off-market data access | How do you find comparable sales for properties that don’t appear on Zillow? | Relies exclusively on MLS and public portal data |
| Contingency vs flat fee | What is your fee structure and when do I pay? | Charges upfront before any result; non-refundable |
| Track record | What percentage of your luxury cases result in a reduction? | Cannot provide data or cites only national averages |
When a DIY Appeal Is Appropriate at the Luxury Tier
There is one scenario where a luxury owner should strongly consider filing themselves: when the appeal ground is a factual error in the property record. If the assessor has your square footage wrong, or has listed three bathrooms when you have five, or has applied the wrong construction quality classification — these errors are indisputable and do not require a comparable evidence strategy. You document the error, file the appeal with supporting evidence (floor plan, permit records, photos), and the correction is usually made at the informal review. For any appeal that turns on market value or comparable evidence, professional representation at $3M+ is the right call.
Ryan Brown, Principal Broker & CEO — Own Luxury Homes®
“I introduced a client to a property tax consultant after he closed on a $14M Coral Gables waterfront. The assessed value came in at $13.8M. The consultant challenged it on equity grounds — comparable properties in the same zip code were assessed at a lower per-square-foot rate. The reduction was $1.1M in assessed value, saving $14,000 in annual taxes. The consultant’s contingency fee in year 1 was about $4,200. The client has kept $14,000 per year since, every year until the next reassessment. The math on hiring the right professional at this tier is not complicated.”
What percentage do property tax consultants charge?
Most full-service consultants charge 25–50% of the first year’s tax savings on a contingency basis. If they achieve no reduction, you pay nothing. Some luxury-tier specialists charge a flat fee plus a contingency percentage. Avoid firms that require large upfront fees before any result.
How do I find a property tax consultant who specializes in luxury?
Ask your real estate agent for referrals — the best luxury consultants are known in the professional network. Interview at least two before selecting. Ask specifically about their experience in your county at your price point. National firms that handle mass volume often underperform at the luxury tier compared to local specialists.
