What Documents Should I Keep and for How Long in 2026

You’re staring at a cabinet that hasn’t been sorted since the last truck was financed, and someone just asked what the company is worth. The 2022 payroll folder is in there. So is a building closing statement, a stack of vendor receipts, and a will nobody has opened since it was signed. The useful question is what documents should I keep and for how long, and the date printed on the paper is the wrong place to start.

The retention clock runs from the last event that still depends on a record, not from the day it was created. A van invoice isn’t finished when that tax year ends. It’s finished when the van is sold and the tax window on that sale closes. A planned sale or a family handover does one more thing. It turns files you treated as temporary into files a buyer, a spouse, or a successor will expect to see.

Retention Periods at a Glance by Document Type

Use one scan on day one. When two rules touch the same document, keep it for the longer one.

Document	Keep for	Why it matters
Federal income tax returns and supporting receipts	3 years from filing	Standard IRS examination window
Records for bad-debt or worthless-securities deductions	7 years	Longer window for loss claims
Payroll and employment-tax records	4 years after tax is due or paid, whichever is later	Employment-tax limitation period
OSHA 300, 300A and 301 injury and illness logs	5 years after the end of the calendar year covered	OSHA access and update period
Employee medical and exposure records	Employment plus 30 years	OSHA medical-record rule
Vehicle, equipment and building purchase and depreciation records	Until the limitation period ends after disposal (usually 3 years)	Basis determines the final gain or loss
Home and rental property purchase and sale records	Until the limitation period ends for the year of sale	Ownership and basis history
Bank and credit card statements	3 years, or 7 if they support a loss claim	Matches the return they support
Customer contracts, warranties and service agreements	Life of the contract plus 6 years	Covers common state written-contract claim windows
Personnel files (hiring, reviews, separation)	7 years after the employee leaves	Common practice for wage and discrimination claims
Corporate minutes, stock ledgers, articles and bylaws	Permanent	Proves ownership and authority
Sale, purchase and closing documents	Permanent	Ownership and tax basis history
Wills, trusts, powers of attorney and certified identity records	Permanent, originals or certified copies with backups	Identity, family and legal authority
UK self-employed business records (HMRC)	5 years after the 31 January submission deadline for the tax year	UK rule; confirm with HMRC

How to read a row that has two clocks

A bank statement that only supports an ordinary return can follow the three-year row. The same statement that proves a bad-debt write-off stays with the seven-year loss file. Federal income-tax, loss, payroll, and property rows follow IRS guidance on how long to keep records. Injury logs and medical files follow OSHA, not the tax calendar. Contract and personnel rows are common practice across many states, not a single federal number, so confirm them before you shred.

A blanket keep everything seven years policy is easy to explain and wrong in both directions. Ordinary returns often need three years. Payroll needs at least four. Ownership papers don’t expire because a calendar page turned. Short destruction creates a hole. Keeping every receipt forever fills the cabinet and still misses the permanent set if nobody labeled it.

State tax agencies, licensing boards, and trade rules can add years. Treat the table as a planning start, not legal advice. Owners cleaning tax files before a sale can pair this schedule with small business tax planning.

If you’re self-employed in the UK, HMRC’s 2026 guidance says business records must be kept for at least 5 years after the 31 January submission deadline for the relevant tax year. Don’t apply the U.S. three-year row to a UK return.

How the Retention Clock Starts and What Extends It

A warranty doesn’t start when the manufacturer printed the card. It starts on the install date. A retention period works the same way. It starts on the last event that still needs the record.

Where each clock starts

• Returns: the filing date, not the year printed on the form.
• A tax payment: the date the money left the account, which can be later than filing.
• Payroll taxes: the due date or the payment date, whichever is later. The employment-tax minimum then runs from that later date.
• A van, lift, or building: the disposal date. Purchase papers and the depreciation schedule stay through the limitation period for the sale year, because basis sets the gain or loss.
• An employee file: the separation date for ordinary personnel records.
• A service agreement: the expiry date, then the claim window that still applies.

IRS recordkeeping rules don’t ask you to keep paper for a fixed habit. They ask you to substantiate every item of income, deduction, or credit for the limitation period that applies. For a refund claim, that means the later of 3 years from the original filing date or 2 years from the date the tax was paid.

A plumbing company buys a van in 2019 and sells it in 2026. The 2019 receipts aren’t “old” in 2023 just because three tax seasons passed. Purchase papers, the depreciation schedule, and the bill of sale stay until the limitation period closes for the 2026 sale year. Shredding them when the 2019 return felt old is how owners lose the basis they already paid tax on.

Keep each record until the latest event that depends on it.

Events that push the date out

Trigger	Keep records until	Add to the file
Open IRS audit or notice	Written close of the case	All returns, receipts and payroll registers for the years in question
Amended return or refund claim	Later of 3 years from filing or 2 years from payment	Original return and proof of payment
Bad-debt or worthless-securities deduction	7 years	Loan records and evidence of the write-off
Sale of the business or a major asset	Limitation period closes for the year of sale	Purchase, depreciation, improvement and disposal records
Lawsuit, claim or workers’ compensation case	Matter resolved, including any appeal	Contracts, incident logs and correspondence
Known OSHA exposure or inspection	Matter resolved	Injury logs, medical files and corrective-action records
Pending sale or succession	Closing or handover complete and any indemnity period ends	Several years of financials, contracts, employee and asset files

A buyer doing diligence doesn’t accept “we think the bookkeeper had that.” Buyers ask for several years of financials, payroll registers, and asset histories. Gaps don’t just slow a deal. They give the buyer a reason to cut the price or to widen an indemnity.

An HVAC owner who plans to sell in 2029 should not shred 2022 payroll files because a seven-year habit feels tidy. Those registers may be the proof behind wages, margins, and who was on the crew.

Before anything goes, run three dates and keep the latest. Use the statutory minimum, the limitation period on the return, and the end of any open audit, dispute, financing, or sale. State and industry rules can sit on top of all three.

Records You Keep Permanently and Why

Some papers don’t support one tax year. They prove who a person is, who owns what, or who has authority to act. A deed is closer to a passport than to a receipt. You don’t throw out a passport because the trip ended.

The states permanently maintain vital records of births, deaths, and marriages because those facts don’t expire. The same idea belongs in a family and a company file. IRS guidance on managing records after you file specifically flags home purchase or sale records, stock transactions, IRA documentation, and business or rental-property records as items that may need to outlast the normal 3-year tax period.

Keep these as originals or certified copies, with a backup:

• Identity and family status: birth, marriage, divorce, death, adoption, and citizenship papers. They settle who is who when a bank, a court, or an estate asks.
• Authority: wills, trusts, and powers of attorney. They say who can sign when the owner can’t.
• The company itself: articles, bylaws or the operating agreement, stock ledgers, and shareholder or membership agreements.
• Property and basis: purchase agreements, closing statements, improvement invoices, loan payoff letters that show a lien was released, stock basis records, and the final sale documents.

Temporary receipts follow the schedule above. Proof of ownership and authority does not. Keep the originals in a fireproof safe or a safe-deposit box, scan a copy to a second location, and write a one-page index that says where each item sits.

A short walkthrough helps when you’re deciding which family and property papers outlive a tax year.

The spouse, the executor, or the person taking over the routes should know where that file lives. After a death or an incapacity, it is often the first thing a bank or a title company requests, and a locked drawer with no key is the same as a missing deed.

Payroll, Injury and Personnel Files to Handle Separately

One folder per crew member feels organized until the clocks disagree. A shock report, a clinic note, and a W-2 are not the same record. Mixing them means the short file gets kept too long, or the long file gets shredded with the short one.

OSHA’s recordkeeping position requires Forms 300, 300A, and 301, or an equivalent, for five years after the end of the calendar year they cover. During that window you must update the 300 log if a case was missed or if the classification, description, or outcome changes. Individual medical records generally stay for the duration of employment plus 30 years, with specified exceptions. Payroll and employment-tax records sit on their own minimum, already in the table, and personnel files commonly run from the separation date.

What each file is for

• The OSHA log has to stay searchable, access-controlled, and tied to the workers’ compensation claim and the corrective action. It isn’t a stack in a job folder.
• The medical and exposure file is confidential. Roofing, electrical, HVAC, excavation, landscaping, and construction crews should split it from the log and limit access to the owner or whoever handles HR.
• Payroll and personnel prove wages, time, hiring, reviews, and the exit. Keep registers, time records, Forms W-2 and W-4, filings, and payment confirmations together by tax year.

An electrician’s shock incident in March 2026 stays on the 2026 log through the end of 2031, and you update that log if the outcome changes. You don’t start a fresh five years from the day someone rewrites the description.

A litigation hold beats the calendar. A workers’ compensation claim, an inspection, or a known exposure pauses routine destruction until the matter is closed, including any appeal.

When a worker leaves, move the personnel file and the medical file to the archive the same week. Start the personnel clock at separation. Write the planned destruction date in a register. Don’t delete from a laptop because the folder looks old. A buyer checking employment history will notice a missing year faster than you’ll recreate it, which is why those files also belong on a financial due diligence checklist before you talk price.

How to Store and Dispose of Records Safely

Scanning isn’t the same as keeping. A photo of a contract that nobody can open in eight years is a picture, not a record.

People do go back to old files. In a 2025 Adobe Japan survey of 400 desk workers, 87.0% said they refer to or reuse digitally stored past business documents in daily work, 32.0% frequently and 55.0% sometimes, according to Adobe’s survey write-up. An archive that only the former office manager can find fails that test.

Split two copies. The working copy lives in the accounting software or the job folder and can be compressed for daily use. The evidentiary copy keeps original metadata, signatures, and the export you could hand an auditor. A cloud export of the general ledger isn’t a substitute for signed contracts, permits, warranties, or proof a customer paid.

Paper goes by year and category in a fireproof cabinet. Digital files live in the books plus one backup that isn’t the same login. Name files so a stranger can search them: year, month, vendor, document type. Write a short access list. When a bookkeeper or office manager leaves, change access the same day and confirm the backup still opens.

A disposal you can explain later

1. Confirm no hold. An audit, a claim, or a sale in progress freezes the shredder.
2. Match the category to the retention table, not to how thick the folder feels.
3. Check the latest date that still depends on the record, including a sale year or a separation date.
4. Destroy every copy. Cross-cut the paper or use a certified shredding vendor, and delete the digital file plus the backup.
5. Log it. Category, date range, and destruction date go in a register so you can show the file was removed on purpose.
6. Review each January after the return is filed, not in a panic when a buyer asks.

Once a year, restore one archived file from backup and open it. Files you expect to need for five or ten years belong in formats other people can still read, such as PDF and CSV, not in a desktop program only one computer still runs.

Build Your Schedule Before You Need It

A schedule you write after the notice arrives is a reconstruction. Build it while nothing is on fire.

1. List every category the business creates, using the rows in the first table, including contracts, permits, and equipment files.
2. Assign a period and a trigger from the events table. A normal receipt and a receipt inside an open claim are not the same item.
3. Name one person per category. The bookkeeper owns tax files. Whoever handles HR owns personnel and medical files. “Everyone” means nobody.
4. Move permanent items into one secure file and put an index page on top that says where each original sits.
5. Put a review on the calendar each January after filing, and tie it to the same week you already block for the return.

If a sale, a handover, or a succession is three to five years out, have the file reviewed now. A missing depreciation schedule is cheap to rebuild from the vendor and the loan file. It is expensive when a buyer is already in the data room. The operating habits behind that review sit with the rest of your business systems and processes, not in a one-time cleanup.

Keep each record until the latest event that depends on it. Nothing here is legal, tax, or financial advice. Confirm state periods, licensing rules, and UK or other non-U.S. requirements with a CPA, an attorney, or the tax authority that governs the return.
