IRS Form 8594 — where the allocation strategy meets the compliance filing.

The PPA negotiation determines the allocation. Form 8594 is where that allocation enters the IRS record. Sellers who negotiate well on PPA but mishandle the filing — inconsistent with the buyer's filing, missing supplemental statements, unsupported FMV — invite audits that can claw back the very benefits the negotiation captured.

§ 01 · The three-part structureWhat each part does.

Part I — General Information. Identifies the parties, date of sale, total sales price, and whether related agreements (employment, consulting, lease, license, supply contract, non-compete) are part of the transaction. The "related agreements" checkbox matters — these often determine whether portions of the allocation should sit in Class V or be reallocated.

Part II — Original Statement. The allocation across seven asset classes using the Residual Method (Section 1060). Lower classes are valued at FMV first; remaining purchase price flows to higher classes; Class VII (Goodwill) catches the residual.

Part III — Supplemental Statement. Filed if subsequent adjustments change the original allocation. Most commonly triggered by earnout payments, working-capital true-ups, indemnification claims that reduce the price, or post-closing adjustments to assumed liabilities. The supplemental rules govern how the change propagates — increases flow forward (Class I → VII), decreases flow reverse (Class VII → II), with a zero floor.

§ 02 · The Residual MethodHow the allocation actually flows.

Step-by-step. Allocate to Class I (cash and equivalents) at FMV. Then to Class II (actively traded securities) at FMV. Then to Class III (accounts receivable, inventory) at FMV. Then to Class IV (stock in trade) at FMV. Then to Class V (tangible and other intangible property) at FMV. Then to Class VI (Section 197 intangibles) at FMV. Whatever purchase price remains is the residual — assigned to Class VII (Goodwill and going-concern value).

The mechanism. Lower-class items have a documented FMV; they get exactly that. Class VII absorbs whatever is left after all the documented items are valued. The seller's strategic goal is to keep lower-class FMVs honest but not inflated — anything saved at the lower classes flows to Class VII goodwill (capital gains, ~20%).

§ 03 · The Consistency RuleWhy both parties' filings must match.

The IRS requires buyer and seller to file consistent Form 8594s. Mismatched filings are a common audit trigger. The buyer expects to amortize Class V intangibles at one number; the seller reports gain at a different number; the IRS notices.

The remedy is process. The PPA allocation should be agreed before closing, signed as an exhibit to the APA, and used by both parties' tax preparers when filing Form 8594. The exhibit becomes the authoritative reference if either filing is challenged.

§ 04 · Part III triggersThe most-missed compliance step.

Earnout payments, working-capital true-ups, and indemnification payments are not anticipated at closing — they happen later. Each requires a Part III supplemental statement filed with the tax return for the year of the adjustment. Missing supplemental statements is a common audit trigger — and earnouts in particular are easy to miss because the timing is months or years post-closing.

The seller's compliance practice. Track every post-closing adjustment. Coordinate with the buyer's CPA on the supplemental allocation. File Part III in the same year as the adjustment, not retroactively. If the adjustment increases the price, the increase typically flows to Class V or VII; if it decreases, the decrease flows the reverse direction, with a zero floor at each class.

§ 05 · The most common audit triggersWhat to avoid.

Inflated non-compete allocation. Buyers sometimes propose 20%+ non-compete allocations for larger amortization deductions. IRS guidelines suggest 2–8%. Inflated allocations invite challenge. Both buyer and seller can be audited.

Missing Part III for earnout payments. An earnout received in Year 3 requires a Part III filed with the Year-3 return. Forgetting the filing is a common error.

Unsupported FMV claims. The IRS expects allocation supported by objective FMV analysis. Engage a business valuation expert; document the rationale; keep the FMV report with the tax records.

The Class VI / Class VII combined-reporting anomaly. The form structurally reports Classes VI and VII as a combined line item. Practitioners often treat the line as ambiguous; the IRS expects the underlying allocation to be tracked separately, even if reported combined. Maintain documentation showing the Class VI breakdown.

§ 06 · Personal goodwill and the gross-up provisionThe advanced moves.

For agencies where personal goodwill is meaningful — the founder's personal client relationships, the founder's professional reputation — sellers can sometimes negotiate personal-goodwill recognition. Personal goodwill is taxed as capital gains to the founder personally, rather than ordinary income through the entity. The structure requires careful documentation and legal support; it is not appropriate in all cases.

The gross-up provision is the safety net. If the IRS audits and adjusts the allocation in the buyer's favor, the buyer reimburses the seller for additional taxes owed. This shifts allocation-audit risk to the buyer and is a powerful negotiation lever — though rarely accepted by sophisticated buyers without significant concessions in return.
