How to Buy a Tax Resolution Firm: The Due Diligence Playbook

Verify case file quality, confirm staff licensing, and protect your investment before closing on an IRS representation or tax debt relief practice.

Find Tax Resolution Firm Acquisition Targets

Acquiring a tax resolution firm offers access to recession-resistant, recurring revenue in a highly fragmented $11B industry. However, buyers face unique risks: contingency-fee revenue tied to multi-year IRS timelines, owner-dependent client relationships, and strict licensing requirements. A disciplined due diligence process across financial, operational, and regulatory dimensions is essential to avoid overpaying or inheriting unresolvable liabilities.

Tax Resolution Firm Due Diligence Phases

01

Financial & Revenue Verification

Validate reported earnings by separating retainer income from contingency fees and confirming collectability of active case receivables.

Revenue Stream Disaggregationcritical

Request trailing 36-month P&L broken down by retainer fees, contingency fees, and installment billing to assess earnings stability and reduce exposure to uncollectable contingency income.

Deferred Revenue & Accrual Accounting Reviewcritical

Confirm the firm uses proper accrual accounting for retainer deposits. Misstated deferred revenue can artificially inflate EBITDA and distort the true purchase price multiple.

Client Concentration Analysisimportant

Verify no single client exceeds 15% of trailing revenue. Flag any large contingency cases that disproportionately skew reported earnings or create binary collection risk post-close.

02

Case File & Pipeline Audit

Assess the quality, stage, and collectability of all active IRS and state tax resolution cases before attributing value to the pipeline.

Active Case File Reviewcritical

Obtain a full case summary report listing each active matter, resolution stage, estimated fees, IRS program type (OIC, installment, CNC), and expected close timeline.

Resolution Rate & Outcome Historyimportant

Request historical case outcome data including acceptance rates on Offers in Compromise and installment agreements. Low resolution rates signal operational or staff quality issues.

Contingency Fee Collectability Assessmentimportant

For contingency cases, estimate realistic collection scenarios under bear, base, and bull outcomes. Apply a haircut to pipeline value for cases in early IRS negotiation stages.

03

Regulatory, Licensing & Operational Review

Confirm firm-level compliance, validate staff credentials, and assess operational systems that reduce owner dependency.

Staff Licensing Verificationcritical

Confirm all practitioners handling IRS representation hold valid EA, CPA, or JD credentials in good standing. Request IRS CAF number documentation for each licensed staff member.

IRS & State Compliance Historycritical

Pull the firm's own IRS transcripts and confirm no outstanding tax liabilities, FTC complaints, state AG actions, or bar grievances related to fee practices or advertising claims.

SOP & Case Management Documentationimportant

Evaluate documented workflows for client intake, IRS correspondence, fee billing, and case handoff. Well-documented SOPs reduce founder dependency and support post-acquisition continuity.

04

Phase 4: SBA Financing and Deal Structure Validation

Verify the Tax Resolution Firm acquisition qualifies for SBA financing, the purchase price is supportable by the verified cash flow, and the deal structure protects the buyer's downside.

SBA Eligibility Confirmationcritical

Confirm the Tax Resolution Firm meets SBA 7(a) eligibility requirements: the business is for-profit, U.S.-based, within SBA size standards, and the buyer meets personal financial requirements. Some industries have specific SBA restrictions — verify before LOI.

Normalized EBITDA vs. SBA Debt Service Coveragecritical

Model verified normalized EBITDA against projected SBA loan payments at current rates. A $1M SBA 7(a) loan at 10.5% over 10 years costs approximately $13,000/month. The Tax Resolution Firm must generate at least 1.25x debt service coverage after a market-rate manager salary to pass underwriting.

Seller Note and Earnout Structure Reviewimportant

Confirm the seller note is properly subordinated to the SBA loan and goes on 24-month standby as required by SBA rules. If an earnout is included, define exact measurement metrics, time period, and dispute resolution process before signing the purchase agreement.

Tax Resolution Firm-Specific Due Diligence Items

  • Obtain IRS Centralized Authorization File (CAF) numbers for all licensed practitioners and verify active power of attorney filings across the case portfolio.
  • Review all client engagement letters to confirm fee structures are compliant with FTC regulations governing tax relief advertising and advance fee collection rules.
  • Assess the firm's Google Business Profile, BBB rating, and Trustpilot reviews as leading indicators of client satisfaction, referral quality, and reputational risk.
  • Confirm the acquiring entity or its principals hold the required EA, CPA, or JD credentials to legally represent clients in IRS proceedings post-acquisition in all active states.
  • Evaluate CPA referral relationships and digital marketing attribution data to determine whether lead flow is replicable or dependent on the seller's personal professional network.
  • Verify that the purchase price divided by verified normalized EBITDA produces a multiple consistent with current market comparables for Tax Resolution Firm transactions — overpaying by 0.5x–1.0x EBITDA is the most common buyer error in this sector.
  • Confirm the lease terms are assignable to the buyer with the landlord's written consent, and that the remaining lease term extends at least through the SBA loan term — lenders require this before funding.
  • Request copies of all material vendor contracts, supplier agreements, and service relationships — confirm which are transferable, which require novation, and which may terminate on change of ownership.

Standard Document Request List

Before signing a Letter of Intent, request these documents from the seller. Missing or incomplete items are a red flag — not a reason to proceed without them.

  • 3 years of business tax returns (Schedule C or Form 1120)
  • Last 3 years profit & loss statements (monthly detail)
  • Current balance sheet and accounts receivable aging
  • Customer/client list with revenue by account (anonymized)
  • All active contracts, subscriptions, and recurring agreements
  • Equipment list with condition and estimated replacement cost
  • Employee roster with tenure, title, and compensation
  • Any pending or threatened litigation or regulatory complaints
  • Owner compensation and discretionary expense add-backs
  • Year-to-date financials vs. prior year same period

Frequently Asked Questions

What is the typical valuation multiple for a tax resolution firm?

Most tax resolution firms sell at 2.5x–4.5x EBITDA. Firms with high retainer revenue, documented SOPs, and licensed staff teams command the upper end of that range.

Can I use an SBA 7(a) loan to acquire a tax resolution firm?

Yes. Tax resolution firms are SBA-eligible. Most SBA-financed deals include a seller note and a 12–18 month consulting agreement to support client and staff retention during transition.

How do I value active case files during due diligence?

Apply a probability-weighted haircut based on case stage and IRS program type. Early-stage OIC cases carry more uncertainty than active installment agreements nearing resolution.

What is the biggest risk when buying a tax resolution firm?

Owner dependency is the top risk. If the founder personally manages all IRS relationships and negotiations, client attrition post-close can materially erode the value you paid for.
