Preparing for a charity audit is easier when it is treated as a project with owners, milestones and review time. The work should not begin when the auditor sends the first query. By that point, the charity should already have closed its records, resolved significant accounting judgements and assembled the core evidence behind the draft accounts.

A 12-week charity audit preparation timeline gives finance staff, senior management and trustees enough space to complete their different responsibilities without turning the audit into an emergency. It also allows questions to be raised while there is still time to find grant agreements, correct fund coding, update forecasts or obtain professional advice.

The exact timetable will vary. A complex group, an international charity or an organisation with a small part-time finance team may need longer. A straightforward charity with strong monthly reporting may need less. The sequence is more important than the precise number of days: confirm the scope, close the records, prepare the accounts, assemble evidence, perform internal review and only then begin fieldwork.

Start With the Signing Date, Not the Fieldwork Date

Many audit plans start by asking when the auditor can begin. A better approach is to identify the final trustee meeting at which the annual report and accounts will be approved, then work backwards. The plan should include time after fieldwork for audit queries, amendments, partner review, going-concern work, trustee circulation and signatures.

The regulatory deadline is the final backstop, not a target signing date. Charities registered in England and Wales generally have ten months from the financial year end to file their annual return and required documents with the Charity Commission. Charitable companies also have Companies House deadlines. A timetable that aims to sign only days before filing leaves no resilience for staff absence, valuation delays, complex evidence or trustee questions.

Agree five dates at the outset: when the first draft accounts will be ready, when the evidence pack will be complete, when fieldwork will start, when the clearance meeting will take place and when trustees will approve the final documents. Place these dates in the board calendar so that trustee availability does not become a late obstacle.

Weeks 12 to 10: Confirm Scope and Responsibilities

The first stage is to define what is being audited. Confirm the reporting entity, legal form, financial year end and applicable accounting framework. Identify subsidiaries, branches, joint arrangements and overseas operations. Check whether consolidated accounts are required and whether another auditor or component accountant will be involved.

The board should also confirm why the audit is required. The trigger may be a statutory threshold, a governing-document clause, a funder condition or a voluntary decision. Thresholds for charities in England and Wales change for financial years ending on or after 30 September 2026, so the organisation should use current Charity Commission reporting guidance rather than relying on last year’s position.

Create a short responsibility schedule. One person should coordinate the audit, but each significant area needs an owner. Grant income may sit with fundraising or programme leads. Payroll evidence may sit with HR. Property documents may be held by an operations manager. Trustee declarations and minutes may be managed by the company secretary. Assigning these owners early prevents the finance team from becoming a messenger for information it does not control.

Ask the auditor for the planned request list and confirm how evidence will be shared. If the audit portal uses a tracker, agree naming conventions and status definitions. Decide who may upload files, who answers queries and who approves proposed adjustments. Access should be secure and limited to appropriate individuals.

Weeks 10 to 8: Perform the Year-End Close

The quality of the audit pack depends on the quality of the ledger. Complete bank reconciliations for every account, including deposit accounts, fundraising platforms, petty cash and accounts that had little activity. Clear old reconciling items or explain why they remain. Reconcile payroll, pensions, VAT where applicable, debtors, creditors, accruals, deferred income, fixed assets, investments and intercompany balances.

Review control and suspense accounts line by line. Round numbers, long-standing balances, unexpected debit creditors and unsupported journals deserve attention. Compare the draft results with the budget, prior year and recent management accounts. Investigate movements that the board or auditor is likely to question.

Fund accounting should be reviewed before the financial statements are drafted. Reconcile opening balances by fund, current-year income and expenditure, transfers and closing balances. Match each material restriction to the grant letter, donor communication or appeal wording that created it. Confirm that expenditure charged to a restricted fund is permitted by its terms and that the remaining balance reflects work still to be delivered.

This is also the time to review the cut-off. Test transactions around the year end to ensure income and expenditure are recorded in the correct period. Consider grant conditions, service contracts, legacies, fundraising events, unspent funding and goods or services received but not yet invoiced.

Weeks 8 to 6: Resolve Judgements and Draft the Accounts

An audit becomes slower when significant judgements are first considered during fieldwork. Prepare position papers for material or unusual matters before the evidence pack is finalised. These may cover income recognition, provisions, impairment, leases, asset valuation, restricted-fund treatment, donated services, going concern or the accounting for a new activity.

A useful position paper is concise. It describes the transaction, identifies the relevant evidence, explains the accounting requirements, evaluates the available treatments and records management’s conclusion. The purpose is not to overwhelm the auditor with technical language. It is to show that the charity has made a reasoned decision supported by facts.

Prepare the first full draft of the financial statements, including notes. Map every figure to the final trial balance and supporting schedule. Check comparative figures and opening fund balances against the signed prior-year accounts. Review the accounting policies for consistency with the charity’s actual activities and the framework applying to the period.

For accounting periods beginning on or after 1 January 2026, charities preparing accruals accounts need to consider Charities SORP 2026. Millet Audit’s article on revenue recognition for small charities explains one area where exchange and non-exchange income require particular attention.

Weeks 6 to 4: Build the Audit Evidence Pack

The evidence pack should make it easy to move from a figure in the accounts to the underlying records. Each material balance should have a lead schedule that agrees to the trial balance. Supporting documents should be labelled consistently, and totals should reconcile without the auditor having to rebuild the schedule.

Provide final documents where possible. A draft bank reconciliation that later changes creates duplicate testing. A grant schedule that does not agree to the ledger generates avoidable queries. If information must be updated later, use clear version numbers and explain what changed.

The core pack will normally include the final trial balance, nominal ledger, draft accounts, bank statements and reconciliations, fund reconciliations, grant agreements, payroll records, debtors and creditors schedules, fixed-asset register, investment statements, trustee and committee minutes, governing document, budgets, cash-flow forecasts and evidence supporting material estimates. The exact request list must come from the appointed auditor.

Do not send large volumes of unstructured information in the hope that the required evidence is somewhere inside. Point the auditor to the relevant clause, transaction or page. A clear evidence trail reduces follow-up questions and helps the audit team understand the conclusion reached by management.

Weeks 4 to 3: Review Controls, Fraud Risk and Compliance

Before fieldwork, management should review the controls that operated during the year and disclose any failures or workarounds. Consider payment approval, online banking, donation processing, cash collection, payroll changes, supplier creation, journals, system access and segregation of duties. Where the same person performs several tasks, identify the independent review or trustee oversight that compensates for the lack of separation.

Update the fraud-risk assessment and discuss it with trustees. Consider both misappropriation of assets and manipulation of financial reporting. Include cyber-enabled fraud, changes to bank details, false suppliers, misuse of cards, unauthorised fundraising and grant fraud. Record actual or suspected incidents and the response taken.

The Charity Commission recommends that trustees review their organisation’s controls regularly. Its internal financial controls guidance covers banking, income, expenditure, related parties, assets and other risk areas.

Compile regulator correspondence, serious-incident reports, legal claims, safeguarding matters with potential financial or disclosure consequences and breaches of funding terms. The aim is not to prejudge the auditor’s view. It is to ensure nothing significant reaches the audit team late.

Weeks 3 to 2: Complete the Trustees’ Annual Report and Going-Concern Assessment

The trustees’ annual report should be drafted early enough for genuine board input. It needs to explain the charity’s purposes, public benefit, activities, achievements, financial performance, reserves, principal risks, governance and future plans at the level required by the applicable SORP tier. The narrative must be consistent with the accounts and with what trustees know about the organisation.

Avoid generic language. A reserves policy should explain the target, the actual level of available reserves and the reason for any difference. The risk section should identify the charity’s real principal risks and how they are managed. Achievements should be supported by credible evidence rather than broad claims.

Trustees must also make and document their own going-concern assessment. Prepare a cash-flow forecast and budget covering the relevant period from the expected date of approval. Identify committed and uncommitted income, restrictions on funds, key cost assumptions and downside scenarios. Explain what actions management could take if income falls or costs rise.

The board should challenge the assumptions before the auditor reviews them. If the forecast depends on an unsigned grant, a refinancing, a major fundraising campaign or the sale of an asset, that dependency should be visible. Optimism is not a substitute for evidence.

Week 2: Perform an Internal Readiness Review

Hold a readiness meeting involving the audit coordinator, finance lead, chief executive and relevant trustee or audit committee chair. Review the request tracker, unresolved accounting issues, missing evidence, draft accounts, annual report and going-concern paper. Confirm that the first version supplied to the auditor is internally consistent.

Read the annual report and financial statements as a complete public document. Check names, dates, charity and company numbers, trustee details, professional advisers, website address and signatures. Reperform key additions and cross-references. Compare fund notes with the Statement of Financial Activities and reserves narrative.

Agree how audit queries will be triaged. Straight factual requests can be answered by the evidence owner. Accounting judgements should be reviewed by the finance lead. Governance, legal or going-concern matters may need chief executive or trustee involvement. A daily review during fieldwork can prevent old queries from remaining open.

Week 1 and Fieldwork: Keep Control of the Process

At the opening meeting, confirm the timetable, team, working arrangements and priority areas. Tell the auditor about important developments since planning. Provide an updated tracker and identify any evidence that is still outstanding.

During fieldwork, answer questions accurately and completely. Where a response relies on a document, attach or link to it. Where the charity disagrees with a proposed treatment, explain the facts and reasoning rather than allowing the issue to drift. Track all proposed adjustments and understand their effect on funds, reserves, covenants and narrative reporting.

Short status meetings can be useful, particularly for a remote audit. They give both sides a chance to clarify requests, identify blockers and confirm which issues require senior input. They should be focused and supported by the shared tracker.

After Fieldwork: Allow Time for Clearance and Approval

The end of testing is not the end of the audit. Management needs time to update the accounts, complete outstanding evidence, review the representation letter and respond to audit findings. The auditor needs time for internal review and final procedures. Trustees need enough time to read the final documents and ask questions.

Schedule a clearance meeting to discuss significant judgements, adjusted and unadjusted differences, control findings, going concern and the expected audit report. Circulate the final accounts and trustees’ report before the approval meeting. The board minutes should record approval and important actions.

After signing, file each document with the appropriate regulator by its deadline. Then convert management-letter recommendations into a tracked action plan. Preparation for next year’s audit should begin with those actions, not with another request list eleven months later.

Make Audit Readiness Part of Monthly Reporting

The strongest charity audit preparation does not happen only at year end. Monthly bank and fund reconciliations, timely management accounts, documented controls, current grant files and regular trustee oversight create evidence as the year progresses. That makes the annual audit a review of an established process rather than a reconstruction exercise.
