Nonprofit Audit Checklist: 47 Items Your Finance Team Needs Before Fieldwork Begins

Audit prep that begins 30 days before fieldwork has already failed. The bank reconciliations that need review, the grant files that need organization, the board minutes that need to be located and confirmed complete — these tasks require 60–90 days of working time, not 30 days of scrambling. A $2M nonprofit with five active grants that starts audit prep in earnest 30 days before fieldwork will spend 80 or more hours assembling documentation while also managing ongoing operations. The same organization that maintained documentation continuously throughout the year spends fewer than 20 hours — presenting organized materials rather than reconstructing them.

The 47 items in this checklist represent 90% of what auditors request in the first week of fieldwork. Organizing them by the six document categories auditors use creates the efficient PBC response that minimizes fieldwork duration.

Why Audit Prep Starts 90 Days Before Fieldwork

The 90-day timeline is not conservative padding — it reflects the sequential dependencies in audit preparation.

Day 90: Year-end close. The fiscal year-end close must be complete before audit prep can begin in earnest. Organizations that have not closed the year cannot produce a trial balance, and without a trial balance, the finance team cannot identify accounts that need reconciliation. A year-end close that takes 45 days leaves 45 days for audit prep — not enough.

Days 60–45: Account reconciliation. All balance sheet accounts — bank accounts, investment accounts, accounts receivable, accounts payable, deferred revenue — should be reconciled and documented before the auditor arrives. Reconciliation items that are found and resolved before fieldwork do not appear in the management letter; the same items found during fieldwork do.

Days 45–30: Grant file review. The grants manager or finance director should review the grant file for every award that will be tested (typically all awards active during the audit period), confirm that documentation is complete, and identify and resolve gaps. An invoice that cannot be located 30 days before fieldwork can sometimes be obtained from the vendor; an invoice that cannot be located during fieldwork becomes a questioned cost.

Days 30–15: PBC list response. When the audit firm sends the PBC list, the organization should be able to respond completely within 15 business days. The PBC list is not a surprise — the major categories are the same every year. Organizations that start collecting PBC items before receiving the list are ahead of schedule.

Days 15–0: Review and organize. A final review of the PBC response to confirm completeness and organization. Auditors who receive a well-organized PBC response with a clear index spend their fieldwork time testing, not searching for documents.

The Six Document Categories Auditors Request

The PBC list for a nonprofit audit is organized around six document categories. Every item in the 47-item checklist falls into one of these categories.

Category 1: Financial Records (Items 1–12)

1. Trial balance as of the fiscal year-end
2. General ledger for the full fiscal year, in accounting system export format
3. Bank statements for all accounts for the full fiscal year
4. Bank reconciliations for all accounts for each month of the fiscal year
5. Investment account statements for the full fiscal year
6. Investment reconciliation and roll-forward schedule (beginning balance + purchases + gains/losses - disposals = ending balance)
7. Accounts payable aging as of year-end with detail of items over 90 days
8. Accounts receivable aging as of year-end with notes on collectibility of items over 90 days
9. Deferred revenue schedule (restricted grant funds received but not yet earned; advance payments)
10. Prepaid expense schedule with documentation of the amortization basis
11. Fixed asset register with beginning balance, additions, disposals, and depreciation for the year
12. Debt schedule (loans, lines of credit) with interest calculations and covenant compliance documentation

Category 2: Grant Documentation (Items 13–24)

13. Fully executed grant agreement for every award active during the audit period
14. All amendments to each grant agreement
15. Approved budget and budget narrative for each active award
16. Budget modification requests and approvals (written) for each award where modifications were made
17. General ledger detail of all expenditures by grant for the audit period
18. Invoices and receipts supporting the five largest expenditures by dollar amount for each active federal award
19. Time and effort documentation for all personnel funded wholly or partially by grants: timesheets for each pay period showing allocation by grant, signed by the employee and supervisor
20. A copy of every interim and final report submitted to each funder during the audit period, with submission confirmation (email receipt, portal confirmation, etc.)
21. Draw requests submitted during the audit period for federal awards, with documentation of cash-on-hand compliance
22. Subrecipient agreements for any pass-through funds, plus monitoring documentation
23. Indirect cost rate agreement with the cognizant federal agency, or documentation supporting use of the 10% de minimis rate under 2 CFR 200.414(f)
24. For awards with a matching requirement: the matching documentation showing the source, amount, and date of all match contributions

Category 3: Board Records (Items 25–31)

25. Board meeting minutes for all meetings during the audit period, signed by the secretary
26. Board committee meeting minutes (Finance Committee, Audit Committee) for the full audit period
27. Resolutions passed by the board during the audit period — budget approval, policy approvals, major contracts
28. Conflict of interest disclosure forms completed by each board member for the audit year
29. Board-approved compensation policy and the most recent executive compensation review
30. Board-approved investment policy
31. Board-approved reserve policy (operating reserve target and draw criteria)

Category 4: Personnel Records (Items 32–38)

32. Offer letters or employment agreements for all current staff and any staff who departed during the audit period
33. W-2s and 1099s issued for the audit year

Category 5: Internal Controls Documentation (Items 39–44)

39. Written accounts payable policy specifying authorization thresholds and approval requirements
40. Written cash receipts policy specifying how donations and other cash receipts are processed and recorded
41. Written purchasing and procurement policy, including sole-source justification requirements
42. Written check signing policy specifying authorized signatories and dual-signature thresholds
43. Documentation of segregation of duties — evidence that the person who authorizes transactions is different from the person who records them
44. IT security policy and evidence of implementation (access review, password policy)

Category 6: Prior Audit Materials (Items 45–47)

45. Prior year financial statements as issued (signed by the auditor)
46. Prior year management letter and all findings from prior year
47. Management’s written response to prior year findings, with evidence that each finding was addressed

Financial Records: What’s Needed and What Format Auditors Want

Auditors prefer financial records in the format that minimizes their processing time. Specific format guidance:

General ledger: exported in a sortable format (Excel or CSV preferred), not PDF. The GL should include transaction date, description, amount, account number, and account description. Auditors will sort by amount to identify large transactions for testing; a PDF export prevents sorting.

Bank reconciliations: the complete reconciliation for each month showing the bank statement ending balance, the book balance, and a reconciliation of all outstanding items. Auditors will select months for testing; having all 12 months organized in a single folder saves time.

Investment statements: the year-end statement plus the monthly or quarterly statements for any periods involving significant transactions. Include the reconciliation between the investment statement and the general ledger.

Grant Documentation: The Complete File for Every Active Award

For each active federal award, the grant documentation section of the PBC response should be organized as a sub-folder per grant, labeled with the award name and number, containing all items 13–24 in a logical sequence.

Items auditors examine most carefully during Single Audit fieldwork:

Time and effort documentation for personnel funded by multiple grants is the most common source of audit findings. Under 2 CFR 200.430, time records must support the allocation of personnel costs to federal awards. Timesheets that show “Grant A: 50%, Grant B: 50%” without daily or weekly detail, or timesheets that are unsigned, are deficient. If time records were submitted to payroll but not retained in the grant file, locate them before fieldwork.

Subrecipient monitoring documentation is required under 2 CFR 200.332. If your organization passed federal funds to another organization, the audit will test whether you (1) executed a written subrecipient agreement, (2) verified the subrecipient’s Single Audit status, (3) performed ongoing monitoring of the subrecipient’s expenditures and compliance, and (4) reviewed the subrecipient’s audit report if applicable. Documentation of each monitoring activity must be in the grant file.

Board Records: Minutes, Resolutions, and Conflict of Interest Disclosures

Board minutes are surprisingly frequently incomplete or missing when the auditor requests them. Common problems:

• Minutes drafted but never formally approved and signed by the board secretary
• Verbal approvals made during board calls that were never documented
• Resolutions referenced in minutes that cannot be located
• Conflict of interest disclosures that were collected for new board members but not renewed annually

The 90-day prep process should include a board records audit: confirm that minutes exist for every meeting during the audit period, that every minute is signed, and that conflict of interest disclosures are current for every board member. Missing minutes can sometimes be reconstructed from agenda, email records, and board member recollections; this is far easier 90 days before fieldwork than during fieldwork.

The PBC List: How to Organize 47 Items Without Scrambling

The organizational system for the PBC response determines whether the auditor experience is efficient or painful.

Folder structure: a shared folder accessible to both your organization and the audit firm (typically a client portal provided by the audit firm), organized by the six category headings above. Each category has a subfolder; within the grant documentation category, a sub-subfolder per grant.

Index document: a single Excel or Word index listing every PBC item, the file name of the document provided, and any notes (e.g., “Item 20 for Grant XYZ — final report submitted 11/15/2025 via funder portal, confirmation email attached”).

Naming convention: consistent file naming that includes the item number: “PBC-15-Grant-Agreement-Smith-Foundation-2025.pdf” is immediately locatable; “Scan0047.pdf” is not.

Status tracking: a column in the index showing status for each item: Complete, In Progress, Not Applicable (with explanation). Auditors can identify what is missing without asking.

Organizations that have maintained continuous documentation throughout the year should be able to complete the PBC response index in 2–4 hours. The remaining time is spent confirming that files are in order, named correctly, and accessible in the shared folder — not searching for documents that may not exist.

DEFINITION

PBC list

Prepared by Client list — the document provided by the audit firm before fieldwork begins specifying every record, schedule, and document the client must provide. The completeness and organization of the PBC response determines how efficiently fieldwork proceeds.

DEFINITION

Single Audit

An audit required under 2 CFR Part 200, Subpart F for organizations that expend $1,000,000 or more in federal financial assistance (raised from $750,000 for fiscal years ending September 30, 2025 or later) in a fiscal year. The Single Audit includes both a financial statement audit and an audit of compliance with major federal program requirements.

DEFINITION

Management letter

A letter from the audit firm to organizational management and the board, typically issued with the audit report, identifying internal control weaknesses and compliance deficiencies observed during the audit. Management letter findings from prior years must be addressed before the current year audit.

DEFINITION

Fieldwork

The period during which auditors are on-site (or connected remotely) examining records, testing transactions, and interviewing staff. Fieldwork duration is directly correlated with the completeness and organization of PBC list responses — disorganized responses extend fieldwork.
