IRS Publication 583 · Document retention
Keep tax records for at least 3 years from the filing date. Employment records require 4 years. Bad debt and worthless securities claims require 7 years. Property records: indefinitely until disposal.
- Lead every filename with ISO 8601 date (YYYY-MM-DD) — the only format that sorts chronologically in any file system.
- Include document type, entity name, and reference number so files are identifiable without opening them.
- Organize workpapers by chart of accounts number (Assets 1XXX, Liabilities 2XXX, Revenue 4XXX) to mirror the trial balance.

Federal requirements
IRS document retention requirements
IRS Publication 583 (Starting a Business and Keeping Records, last revised December 2024) defines how long to keep tax records. The retention period depends on the action, expense, or event the document supports. The clock starts from the later of your return filing date or the return due date (including extensions).
General rule for income, deduction, and credit records
From the later of the filing date or due date (including extensions). Covers most invoices, receipts, and bank statements.
Employment tax records
W-2s, payroll journals, Form 941 records — kept at least 4 years after the tax becomes due or is paid, whichever is later.
Unreported income exceeding 25% of gross
If you fail to report income exceeding 25% of gross income on your return, the IRS has 6 years to assess additional tax.
Bad debt deductions and worthless securities
Claims of loss from worthless securities or bad debt deductions require 7-year retention under IRC §6511(d).
No return filed or fraudulent return
No statute of limitations applies. Also applies to property/asset records — keep until the period of limitations expires for the year you dispose of the property.

State requirements
State-by-state retention requirements
State requirements often exceed IRS minimums. Multi-state businesses must follow the strictest applicable standard — for most firms, California's 8-year requirement is the practical floor.
| State | Period | Notes |
|---|---|---|
| California | 8 years | Strictest major state. FTB uses a 4-year SOL for assessment, but practical guidance is 8 years. Extended to 12 years for abusive tax avoidance transactions. |
| New York | 4 years | 3-year standard SOL, 6 years if substantial understatement. Payroll records: 4 years minimum. |
| Texas | 3 years | No state income tax. Retention applies to sales tax and franchise tax records. |
| Florida | 5 years | No state income tax. 5 years for business records. 3–5 years depending on document type. |
| Illinois | 5 years | 3-year standard SOL. Corporate income tax records: 5 years recommended. |

Tax form reference
What each tax form is and how to name it
Every tax engagement involves the same core forms. Consistent naming eliminates the annual scramble of matching unlabeled PDFs to the correct line items on a return.

{TaxYear}_K1_{Entity}_{Partner}.pdf2025_K1_AcmePartners_JohnSmith.pdfAudit & tax prep workflow
PBC lists and the “47 unlabeled PDFs” problem
A PBC (Provided By Client) listis the formal checklist of supporting documents an auditor or tax preparer sends to clients before fieldwork begins — typically 2–4 weeks before the engagement start date. It's the primary driver of audit and tax return completion timelines.
What a typical PBC list requests
Before and after: PBC document naming
Clients dump unlabeled files into a shared folder. AI-powered naming transforms the folder before the audit team opens a single file.

Professional standards
Workpaper organization by trial balance account
Workpapers (working papers) are the supporting documentation a CPA maintains for each engagement. The standard organization follows the chart of accounts numbering system, mirroring the trial balance structure so reviewers can navigate directly from a line item to its supporting documentation.

|---|---|---|
| 1000–1999 | Assets | 1010_Cash_BankRec_2026-02.xlsx |
| 2000–2999 | Liabilities | 2010_AP_Aging_2026-02.xlsx |
| 3000–3999 | Equity | 3010_RetainedEarnings_Rollforward_2026.xlsx |
| 4000–4999 | Revenue | 4010_Revenue_Detail_2026-02.xlsx |

Comparison
Document management tools compared
Most accounting tools focus on capturing new documents going forward. The gap is in organizing existing file archives retroactively — the thousands of PDFs already in your cloud storage with names like scan001.pdf.

FAQ
Frequently asked questions
How long should I keep accounting records for IRS compliance?
The IRS general rule (Publication 583) is 3 years from the filing date or due date, whichever is later. However, employment tax records (W-2s, payroll) require 4 years. Bad debt deductions and worthless securities claims require 7 years. Property and asset records should be kept indefinitely until disposed of, plus 3 years. If you operate in California, keep records for at least 8 years — the strictest state requirement.
What is a PBC list and why does document naming matter for it?
PBC stands for Provided By Client — it's the checklist of documents an auditor or tax preparer sends to clients before fieldwork begins. Clients typically respond by dumping dozens of unlabeled files into a shared folder (the classic "47 files named scan001.pdf" scenario). Consistent naming conventions eliminate the manual matching step: if files arrive as 2025_W2_AcmeCorp_JohnSmith.pdf instead of scan047.pdf, the audit team can match them to PBC line items instantly.
What naming convention should I use for invoices?
Use YYYY-MM-DD_Vendor_INV-Number_Amount.pdf (e.g., 2026-02-15_AcmeSupply_INV-10234_1250.00.pdf). Leading with ISO 8601 date format ensures chronological sorting in any file system or cloud storage provider. Include the vendor name and invoice number for instant identification without opening the file.
How should I organize workpapers by trial balance account?
Follow the chart of accounts numbering: Assets (1000–1999), Liabilities (2000–2999), Equity (3000–3999), Revenue (4000–4999), Expenses (5000–7999). Create folders by account range and name workpapers with the account number prefix: 1010_Cash_BankRec_2026-02.xlsx, 2010_AP_Aging_2026-02.xlsx. This structure mirrors the trial balance and makes workpaper review systematic.
Should I use calendar year or fiscal year in file names?
Use whichever matches the entity's tax year. For fiscal year filers, prefix with FY and the ending year: FY2026_Q3 for a fiscal year ending June 30, 2026. For calendar year filers, use standard YYYY-MM-DD. If a firm handles both, include a FY/CY prefix to prevent confusion: FY2026_Q3_AcmeCorp_TrialBalance.xlsx vs CY2026_Q1_SmithLLC_TrialBalance.xlsx.
What is the difference between Dext and renamed.to for accounting document management?
Dext (formerly Receipt Bank) captures new documents going forward — you photograph receipts or forward emails, and Dext extracts data and pushes it to your accounting software. Renamed.to solves a different problem: organizing existing files. If you have thousands of PDFs in Google Drive or Dropbox with names like scan001.pdf, renamed.to reads each document with AI/OCR and renames them in place. The two tools are complementary, not competing.
How can I automate naming hundreds of scanned invoices?
Connect your Google Drive or Dropbox folder to renamed.to. The AI reads each scanned PDF using OCR, extracts vendor name, date, amount, and invoice number, and suggests a standardized filename. You preview every suggestion with confidence scores, then approve the batch. Accounting firms typically process 1,000+ documents in under 3 minutes. Custom naming templates can be saved per client and reused monthly.
