Protecting Buyers From Surprise Bills in M&A –
The Hidden Tax Dangers in M&A
You just closed a $50 million acquisition. Six months later, the IRS comes knocking—the target company underpaid taxes by $2.3 million. Who pays? Without proper protections, the buyer does.
At Secured Trust Escrow, we’ve seen tax surprises derail countless deals. That’s why sophisticated buyers use tax liability escrow—a financial airbag that protects against:
✔ Unpaid income/payroll taxes
✔ Sales tax audits
✔ Transfer tax disputes
✔ International VAT exposures
Here’s how it works.
How Tax Escrow Works: A 3-Step Shield
1. Pre-Deal Tax Review
– Phase 1: Buyer’s tax team identifies potential exposures
– Phase 2: Quantifies worst-case liabilities (usually 5-15% of deal value)
Common Red Flags:
– Unfiled state sales tax returns
– Aggressive R&D credit claims
– International transfer pricing risks
2. Escrow Agreement Terms
✔ Amount Held: Typically 5-20% of purchase price
✔ Duration: 12-36 months (matches statute of limitations)
✔ Release Conditions:
– Clean tax clearance certificates
– Expiration of audit periods
– Resolution of disputed items
3. Post-Closing Protection
– Escrow covers:
– IRS/state tax assessments
– Defense costs
– Indemnity claims
3 Real-World Tax Escrow Scenarios
Case 1: The $18M California Sales Tax Surprise
A tech buyer discovered post-closing that the target never remitted $2.1M in sales tax. The 10% tax escrow covered the bill plus penalties.
Case 2: International VAT Timebomb
A UK acquisition revealed unpaid EU VAT liabilities. The €4M escrow holdback prevented buyer losses.
Case 3: Payroll Tax Nightmare
An IRS audit found misclassified contractors owed $850K in back payroll taxes—paid from escrow.
Key Structuring Decisions
| Consideration | Buyer-Friendly | Seller-Friendly |
| Escrow Amount | Higher (15-20%) | Lower (5-10%) |
| Duration | Longer (36 months) | Shorter (12 months) |
| Release Triggers | “No assessments” vs. “No known issues” | Good |
| Dispute Resolution | Arbitration preferred | Good |
Emerging Trends in Tax Escrow
1. Pass-Through Entity Escrows
Special structures for S-corps/LLCs where tax liabilities flow through to buyers.
2. Green Energy Tax Credit Escrows
Holdbacks for IRA (Inflation Reduction Act) credit recapture risks.
3. Crypto Tax Escrows
Withholding for potential IRS challenges on blockchain transactions.
When Tax Escrow Isn’t Necessary
Consider alternatives when:
✔ The target has pristine tax compliance records
✔ Deal size is too small to justify escrow costs
✔ Buyer assumes all tax risks (rare in mid-market+)
Why Choose Specialized Tax Escrow?
Generic escrow agents often miss:
✔ Jurisdictional nuances (California FTB vs. Texas Comptroller)
✔ Statute of limitation differences
✔ Pass-through entity complexities
At Secured Trust Escrow, our tax attorney-vetted escrow agreements address these pitfalls.
