What work exists at the cutoff date?
List engagement-level work that has started, finished, been reviewed, or remains dependent on client inputs, but has not yet been billed. Identify the service, fee arrangement, status, responsible team, expected bill, prior payments, remaining duties, and unresolved issues. A total work-in-process balance alone may conceal very different completion and collection prospects.
The seller hub places closing balances within the wider transaction. Unbilled work at practice closing needs a defined cutoff and a documented division of fee rights, work, cost, client communication, and evidence. Seller and buyer should not each assume the other will complete necessary tasks while each also expects to receive the associated cash.
Distinguish the ledger measure from the agreement’s treatment. A time-based WIP schedule, fixed-fee engagement status, tax-return completion stage, and contract right to bill can describe different things. Identify what each number represents before applying a percentage or placing it in the closing statement.
How should accounting basis be kept separate from contract rights?
The IRS Publication 538 describes cash and accrual income timing as general accounting-method concepts. Its published revision is January 2022; have advisers review current rules and the actual taxpayer. Whether an amount appears in historical taxable revenue does not itself decide who receives a postclosing fee or who must finish the underlying engagement.
Unbilled-work cutoff schedule means an engagement-level record defining status, supported fee measures, prior payments, remaining obligations, and agreed treatment at a specified transaction date. It should connect the financial balance with real completion and collection responsibilities rather than assume every recorded hour is a collectible acquired asset.
Review engagement terms, billing practices, ownership documents, and the actual sale agreement with advisers. Work performed before closing, an invoice issued afterward, and cash collected later can involve separate dates. A clear schedule should show those dates without silently treating all later cash as new buyer revenue or all earlier effort as seller consideration.
What should the engagement schedule contain?
Use stable reviewed identifiers, service scope, fee basis, agreed amount where supported, hours or status where meaningful, billed amounts, payments, work remaining, responsible people, and exceptions. Reconcile totals with the ledger and the proposed closing treatment. Keep the basis consistent across schedules so buyers can compare evidence without guessing which definition changed.
| Field | Question | Reason |
|---|---|---|
| Status | What is actually completed and reviewed? | Identify remaining qualified work |
| Fee basis | Is billing hourly, fixed or otherwise defined? | Avoid converting time directly into collectible value |
| Prior money | What was billed or received already? | Prevent duplicate fee rights or balances |
| Exceptions | What inputs, disputes or approvals remain? | Explain uncertainty and completion conditions |
The document-preparation guide supports reconciliation. Preserve protected source evidence and identify any estimate. A schedule can remain useful with stated limitations; unsupported precision can make a time balance look like guaranteed cash even when scope, approval, or client payment remains uncertain.
How should value and remaining cost be evaluated?
Assess the actual fee arrangement, work completed, quality, review needs, client inputs, collectability, and remaining delivery cost. Do not assume that 60 percent of recorded hours automatically earns 60 percent of a fixed fee. Some tasks, review steps, or contractual conditions may be essential before any bill or completion claim is supported.
For illustration, an engagement with an agreed $2,000 fee might require $600 of remaining qualified delivery cost under a documented scenario. A proposed fee allocation still needs review of work status, prior payment, contractual rights, and collection risk. These invented amounts show separate measures; they are not a standard valuation method or assurance that $1,400 belongs to the seller.
Consider who controls completion and billing after closing. A seller fee right may depend on the buyer’s cooperation, while a buyer finishing work may need valid access and client arrangements. Reconcile those dependencies through actual duties and procedures rather than leave value based on a party’s informal expectation of help.
Which treatment options should be compared?
The parties may discuss retained seller billing, acquired rights, a supported closing adjustment, separate completion compensation, or another reviewed mechanism. These are potential contract choices, not universally available or appropriate terms. Compare fee rights, completion costs, collection handling, timing, taxes, client arrangements, and financing constraints for the actual proposal.
The IRS sale-of-a-business explanation discusses tax analysis of separate transferred assets. The IRS Form 8594 instructions addresses allocation reporting for applicable asset acquisitions. Ask advisers how the actual rights and payments are treated, rather than call every WIP amount goodwill or assume an invoice-based split settles its tax classification.
The asset-versus-equity guide provides broader structure context. An entity acquisition can involve balances and historical obligations differently from a selected-asset transaction. The cutoff schedule should reflect the actual legal scope and approvals, without borrowing a generic asset-sale convention solely because it seems easy to calculate.
Who completes, reviews, and files unfinished tax work?
Identify the continuing provider, qualified preparation and review, client authorizations, filing readiness, and communication. The IRS EFIN frequently asked questions states that an EFIN is not transferable. Acquiring an unbilled engagement does not itself authorize the purchaser to use the original provider’s filing identity or personal credentials.
The client-transfer guide supports assignment of contacts and duties. Review new or continuing engagement requirements for the actual transaction. Clients should understand whom to supply missing information to and who is responsible for completion, without a misleading assumption that the seller remains indefinitely available.
Document a process for new scope or problems discovered after closing. A missing item, amended instruction, notice, or quality concern can change required effort. Specify who approves additional work and how responsibility is reviewed. A cutoff allocation should not force parties to hide an issue simply because it was not visible in the first WIP schedule.
How should collection and disputes be handled?
Define invoice authority, payment destination, remittance timing, reporting, offsets where reviewed, and evidence for disagreements. Track amounts received against stable engagement identifiers and avoid mixing prior-work cash with the buyer’s new services without a reconciliation. Clients should receive accurate billing information that matches the actual rights and service arrangement.
The IRS Section 7216 information center describes separate tax-return-information duties. Collection cooperation and evidence sharing need appropriate purpose, records, recipients, and review. A fee dispute between buyer and seller does not provide universal permission to disclose full taxpayer files to every participant.
Review professional or claim concerns with appropriate advisers rather than treat every unpaid fee as a simple collection failure. Preserve source records and context. The agreement should establish a dispute process that permits responsible service and evidence review while keeping protected information and ongoing client needs under control.
How should the cutoff be verified and maintained?
Set the date and time, required schedules, review process, permitted access, exceptions, signing responsibility, and later adjustment procedure. Compare the closing version with recent billing and cash records so newly billed or paid items do not remain duplicated in WIP. Identify who maintains the postclosing register and how corrections are supported.
- Define the cutoff and actual unbilled engagement population.
- Reconcile status, fee basis, prior money and remaining work.
- Review rights, value, tax treatment and financing constraints.
- Assign qualified completion, filing and collection responsibilities.
- Maintain reporting, corrections and a protected dispute process.
The resulting schedule should explain both money and work. A purchaser needs to fund remaining delivery, and the seller needs clear supported fee rights and evidence. Reconcile those answers before closing so a familiar WIP label does not carry several incompatible assumptions about who performs, bills, receives, or owes the engagement’s remaining obligations.
A few common questions
What else should you know?
Does every recorded WIP hour have purchase value?
Review actual fee arrangements, completed and reviewed work, client inputs, remaining costs, approval conditions, and collectability. Recorded time may describe effort rather than a supported billing right or guaranteed cash. A fixed-fee engagement needs its own analysis; do not automatically convert a percentage of hours into the same percentage of collectible value.
Who receives a fee billed after closing for earlier work?
The actual agreement should define rights, cutoff, work status, prior payments, completion duties, collection handling, and tax review. Billing or receipt after closing does not alone settle ownership of the fee. Reconcile the engagement-level schedule with the transaction structure rather than assume all later cash belongs automatically to either party.
Can the buyer file unfinished returns with the seller’s EFIN?
The IRS states that an EFIN is not transferable. Review the continuing provider’s authorization, client arrangements, preparation, review, filing responsibilities, and required updates. Purchasing unfinished engagements or obtaining software access does not establish permission to use another provider’s filing identity or personal credentials. Fund the actual authorized completion route.
How should WIP disagreements be resolved after closing?
Use agreed definitions, stable engagement identifiers, source records, reporting, correction procedures, and a reviewed dispute process. Separate prior-work receipts from new services and document remaining obligations. Protect client information when sharing evidence, and involve appropriate advisers for professional or claim concerns rather than treat every disagreement as permission for unrestricted file disclosure.
