How can a tax and utility recovery firm get more clients?

Sales tax and utility bill recovery firms find money a business has already overpaid: sales tax charged on exempt purchases or exempt utility use, and billing errors on electric, gas, water and telecom accounts. The service is B2B, the fee is commonly a share of what is recovered, and the buyer is a controller, CFO or owner who has never heard of the firm. That combination makes this a prospecting business, not a search business.

Mostly, they do not look. Search demand is close to zero.

In the Strive analysis of Google Keyword Planner data from September 2025 to August 2026, only 3 terms in this vertical registered measurable national volume¹. “utility bill audit”, “utility audit” and “utility auditing” each sat in the 100 to 1,000 monthly range, with top-of-page bid estimates (high range) of $21.61 to $24.00. Smaller terms such as “telecom audit” and “utility bill audit companies” were in the 10 to 100 range¹. No sales tax recovery term surfaced at all, and none of the state reports met the publishing threshold¹. Keyword Planner volumes are ranges, and bids are Google’s estimates, not cost per click or cost per lead.

So the demand is not measured in search. It exists in the books of every business that buys a lot of taxable goods or pays large utility bills, and it is found by outreach, partners and referrals. A small paid search campaign can catch the few people who do search, but it will not fill a pipeline.

No public, sourced benchmark exists for contingency rates or average recoveries in this industry. Rates and results vary with the client’s size, industry and state. Build your numbers from your own audits.

Worked example 1: one Texas manufacturing meter

Illustrative inputs, not sourced:

• A manufacturer’s electric bill on one meter: $40,000 a month
• The meter has been charged sales tax at a combined 8.25% (Texas allows a 6.25% state rate plus up to 2% local⁶)
• A predominant use study shows more than 50% of that meter’s electricity powers exempt manufacturing, so the whole meter qualifies⁵⁷

Tax per month: $40,000 × 0.0825 = $3,300. Four-year lookback⁴: $3,300 × 48 = $158,400 potential refund, before any adjustments the Comptroller makes. At an illustrative 30% contingency fee: $47,520.

That is one meter at one company. It also shows why the deadline matters: each month that passes, the oldest month falls outside the four-year window⁴.

Worked example 2: value of one lead

Illustrative inputs across a mixed pipeline:

• Leads who agree to an audit: 20%
• Average recovery per audited client (many find little, a few find a lot): $25,000
• Contingency fee: 30%, so $7,500 per audited client
• Gross margin after analyst time and engineering studies: 50%

Gross profit per audited client: $7,500 × 0.50 = $3,750. Gross profit per lead: $3,750 × 0.20 = $750.

At a $20 click (below the $21.61 to $24.00 bid estimates¹) and a 5% click-to-lead rate, a search lead costs $400, which works on paper. The limit is volume: three terms in the 100 to 1,000 monthly range nationally¹ cannot supply a firm. Outbound and partners must carry it.

Ranked for a small firm.

CPA partners

CPAs see the tax returns and the utility expense lines. Many prefer to send recovery work out rather than staff it. Know their rules before you offer anything:

• In Texas, a CPA may not take a commission or referral fee for referring a client for whom it performs work requiring independence, such as an audit, and must disclose any permitted referral compensation to the client in writing, including its nature, source and amount, no later than the referral¹³.
• Texas CPAs also may not work on a contingent fee for clients that need independence, or prepare an original or amended tax return on contingency during an engagement requiring independence¹⁴. A CPA who audits the client’s financial statements usually cannot be your contingency partner on that client.

The simplest partner offer is no fee at all: you send the CPA tax work you find, and the CPA sends you clients with large spend.

Account-based outreach

Pick industries where the math is large: manufacturers (electricity used in exempt processing), restaurants and hotels (utility-heavy), multi-site retailers, hospitals, and companies with large equipment purchases. Build a list of 100 to 300 target companies, find the controller or CFO, and lead with the deadline and a no-cost first look.

Cold email to businesses is legal under CAN-SPAM if it follows the rules. The FTC says the law “makes no exception for business-to-business email.” Each message needs accurate header information, a subject line that matches the content, clear identification as an ad, a valid physical postal address, and an opt-out you honor within 10 business days. Penalties can reach $53,088 per violating email¹⁵. You may not require a recipient to pay a fee or give any information beyond an email address and opt-out preferences to unsubscribe¹⁶. If an email mixes a relationship message with a pitch, the FTC’s primary-purpose test decides whether it counts as commercial, based largely on the subject line and what appears first¹⁷.

Phone calls to a business are exempt from most of the Telemarketing Sales Rule, but not from its bans on misrepresentation and false or misleading statements¹⁸. Script the call around what the audit checks, never around a promised result.

Associations and trade shows

State manufacturers associations, restaurant and lodging associations, and controller or CFO groups gather the buyers in one room. A speaking slot on “four years of refunds you may be leaving behind” earns more meetings than a booth. Bring the Comptroller’s own refund rules as the handout⁴.

Energy brokers and facility consultants

Electricity brokers and facility managers already hold utility bills and letters of authorization. They can be partners, but they may also see your audit as a review of their own work. Agree up front on who owns which finding.

Public sector work

Cities, counties and school districts may buy utility audit or cost recovery services through formal solicitations. Watch your state and local procurement portals. Expect long timelines and fixed formats.

This is not legal or tax advice. Talk to a state and local tax attorney or CPA about any specific claim.

Refund deadlines

In Texas, the refund statute requires a written claim stating the specific grounds, filed within the limitation period, and says that failing to file a timely claim waives any demand against the state for the overpayment². The four-year assessment limit runs from when the tax becomes due and payable³. A claim tolls the statute only for the specific reasons it states, and it must include all required elements to do so⁵.

Who may file and how

• The Texas Comptroller accepts claims from permitted sellers and permitted purchasers. A purchaser without a permit must first ask the seller for the refund, and the seller may instead give the purchaser Form 00-985, Assignment of Right to Refund, so the purchaser can file directly⁴.
• If anyone other than the taxpayer, such as an accountant, attorney or recovery firm, files the claim, it must include Form 01-137, Limited Power of Attorney⁴.
• The Comptroller may request invoices, proof of payment, resale certificates and other support⁴, and its FAQ says requested documentation is due within 30 days⁵. Collect documents before you file, not after.

The Texas utility exemption, in detail

Texas exempts gas and electricity sold for residential use and for listed uses including powering exempt manufacturing equipment, lighting, cooling and heating in manufacturing areas, and agriculture⁷. When one meter measures both exempt and taxable use, the whole meter is exempt or taxable based on the predominant use⁷. The Comptroller says a complete predominant use study covers 12 consecutive months, shows more than 50% exempt use, is certified by a registered engineer or a person with an engineering degree from an accredited college, and carries the owner’s certification of the equipment list and hours of use⁵. That makes the engineering study a cost in your fee model.

Utility billing error rules

Utility refunds follow tariffs and commission rules, not tax law:

• PG&E’s Electric Rule 17.1 refunds overcharges from billing errors for up to three years, or only the months of the error if shorter, without interest¹⁰.
• In Texas, when a retail electric provider overbills, the bill must be corrected for the entire period of the overbilling, and the provider owes interest if it does not correct the error within three billing cycles¹¹.
• Texas lets larger non-residential customers agree in writing to different customer protections than the rules provide¹². Read the contract before you promise a client the default protections.

Claims to keep out of your marketing

• “We guarantee a refund” or any average recovery you cannot document.
• “The state owes you money” before an audit has found anything.
• Implying you are affiliated with the Comptroller, a utility or the client’s CPA.
• Implying a business needs a firm to claim a refund. A business can file its own claim with the Comptroller⁴.

No sourced data shows a seasonal pattern, and the keyword data is too small to show one¹. Two calendar effects are worth planning around. First, the refund window rolls forward monthly, so every month of delay costs a prospect one month of refunds in Texas⁴. Second, finance teams are busiest at year-end close and tax deadlines and more open to outside reviews between them. Treat that second point as a planning assumption and check it against your own reply rates.

• Waiting for search traffic. There is almost none¹.
• Offering CPAs referral fees without checking their rules. Independence limits and written disclosure apply in Texas¹³¹⁴.
• Sloppy cold email. No postal address, a misleading subject line or ignored opt-outs turn a cheap channel into a liability¹⁵¹⁶.
• Promising results before the audit. It erodes trust and invites deception claims.
• Underpricing the work. Engineering studies, document collection and amended filings cost money; build them into the contingency rate.
• Vague contracts. Define what counts as a recovery (refunds, credits, future savings) and for how long the fee applies.

• Search demand is tiny, so outbound, CPA partners and associations carry this business.
• The refund deadline is the strongest message: four years in Texas, three in Florida and New York.
• Texas utility recovery turns on the predominant use study and its specific requirements.
• CPAs face referral-fee disclosure and independence rules, so build partnerships that respect them.
• B2B cold email is legal only when it meets CAN-SPAM, and no recovery should be promised before the audit.
