What Documents Do You Need for a Business Valuation? The Complete Checklist
By Bill Anderson, FCCA, Chief Executive Officer, Assetica — 2026-08-13
A valuation cannot be built from a conversation; it is built from evidence, and the single biggest reason engagements stall is that the evidence is assembled in stages instead of all at once. Here is exactly what a valuer needs from financial statements, tax filings and corporate records to contracts, asset registers and forecasts, why each one matters, a purpose-by-purpose breakdown, and what to do if your bookkeeping is behind before you start.
The documents every valuation needs
Whatever the reason for the valuation, sale, bank finance, a dispute, a tax position or an investment, the request list draws from five core categories: financial statements or management accounts, tax filings, corporate and legal documents confirming ownership, contracts with customer and supplier concentration data, and an asset register where property, plant or equipment are material.
Financial statements and management accounts: how many years are needed
Three years is the working standard for most commercial valuations, enough to establish an earnings trend and a normalisation base. Audited accounts are the strongest evidence; where they do not exist, well-kept management accounts supported by a trial balance and general ledger are the fallback, alongside current year-to-date figures up to the valuation date.
Tax filings, corporate and legal documents
Corporate tax returns and VAT filings cross-check reported income against the management accounts and surface related-party items or owner remuneration that needs normalising. Corporate and legal documents, trade licence, MOA/AOA, shareholder register and cap table, confirm exactly what entity and what stake is actually being valued before any analysis proceeds.
Contracts, concentration data and asset registers
Material customer and supplier contracts and a revenue-by-customer breakdown let the valuer assess how sustainable current earnings are and whether a concentration discount applies. A fixed asset register with depreciation schedules and property or equipment records supports an asset-based approach and checks book value against reality.
Forecasts and purpose-specific extras
A forecast with documented assumptions is needed for a discounted cash flow valuation, an early-stage business or an investment raise, but not for a straightforward historical market-multiple valuation. On top of the core document set, the purpose of the valuation, bank lending, divorce, shareholder dispute, tax or transfer pricing, or a visa application, adds its own specific supporting documents.
Incomplete records and catching up bookkeeping
Informal or incomplete records are common in family businesses and SMEs and are not, on their own, a reason a valuation cannot proceed, though they add time while the valuer reconstructs and verifies the true position. Bringing bookkeeping up to at least trial-balance level before the engagement starts, and disclosing any gaps upfront, is the fastest way through the process.
Frequently Asked Questions
Do I need audited accounts for a business valuation?
Audited accounts are the strongest evidence available, but not always essential. Well-kept management accounts, supported by a trial balance and general ledger, are an acceptable substitute for most commercial valuations, particularly for SMEs where a full audit was never a statutory requirement.
What if my business has no formal financial statements?
A valuation can still proceed from bank statements, invoices and bookkeeping exports, but expect it to take longer, since the valuer first has to reconstruct a reliable financial picture before analysing value at all. Flagging this at the outset keeps the process as efficient as possible.
How many years of accounts do I need for a valuation?
Three years is the standard for most commercial valuations, enough to establish a genuine earnings trend without leaning on figures that have become less relevant to the business today. Cyclical businesses sometimes need five years, while early-stage businesses may have less than three to draw on.
What documents does a bank need for a lending valuation?
Alongside the core financial, tax and legal documents, a bank-focused valuation typically needs existing facility agreements, details of security already in place, personal guarantees, and aged debtor and creditor listings the credit team uses to assess working capital and downside risk.
What extra documents does a divorce or shareholder dispute valuation need?
These engagements carry a higher evidence bar because the report may be challenged by an opposing expert. Expect to provide full financial disclosure, a clear separation of personal and business assets, historic drawings or distributions, and any correspondence relevant to the matters in dispute.
Do I need to provide customer and supplier contracts?
For most engagements, yes, particularly where the business relies on a small number of key relationships. Contracts and a revenue-by-customer breakdown let the valuer assess how sustainable current earnings genuinely are and whether a concentration discount should be applied.
What if my business has multiple entities or a group structure?
You will need a group structure chart and, where they exist, consolidated figures, along with documentation of any related-party transactions or intercompany balances. Groups that have never produced consolidated accounts before should expect this reconciliation step to add time.
Can a valuation proceed if my bookkeeping is behind?
Yes, but it is worth bringing your records up to at least trial-balance level before the engagement starts if the deadline allows for it. Catching up in parallel with the valuer's own work is slower than resolving the gap first, and disclosed gaps are far easier to work around than discovered ones.
Do I need a forecast if I only want a current valuation?
Not always. A market-multiple valuation of an established, stable business can often be built from historical earnings alone. A forecast becomes necessary for a discounted cash flow approach, an early-stage business without a long earnings history, or a valuation supporting an investment raise.
How long does it take to gather the documents?
For a business with reasonably organised records, most of the core document list can be assembled within a few business days. Businesses with informal records, unconsolidated entities, or undocumented related-party arrangements should expect this stage to take longer, and it is usually the biggest driver of how quickly the whole engagement moves.
Who should I send the documents to, and how?
Your valuer will confirm a secure method, typically a shared, access-controlled folder, and it is worth designating one person on your side who can respond quickly to follow-up questions, rather than routing requests through several people in turn.
What happens to my documents after the valuation is complete?
A reputable, independent valuer will confirm their data handling and retention approach at the outset of the engagement. Documents provided are used solely to prepare the report and are handled under the confidentiality terms of your engagement letter.
