AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
The IRS generally expects records supporting a return to be kept for at least three years after filing, with longer periods in some cases: six years if income was substantially under-reported, seven for bad debt or worthless securities claims, at least four for employment tax records, and indefinitely if no return was filed. An AI agent can file each record against the transaction it supports and hold the retention date, so nothing is lost or deleted early.
The IRS periods, in summary
The IRS's guidance on how long to keep records ties each period to the time it has to assess additional tax, known as the period of limitations. The table below summarises the main cases it lists. Your own situation may need longer, and state tax agencies and other laws can set their own periods.
| Situation | Keep records for |
|---|---|
| You owe additional tax and none of the cases below apply | 3 years after filing |
| You claim a loss from worthless securities or a bad debt deduction | 7 years |
| You do not report income you should, and it is more than 25% of the gross income shown | 6 years |
| You do not file a return | Indefinitely |
| You file a fraudulent return | Indefinitely |
| Employment tax records | At least 4 years after the tax is due or paid, whichever is later |
Records relating to property, such as equipment or a building, should generally be kept until the period of limitations expires for the year in which you dispose of the property, because you need them to work out depreciation and any gain or loss.
Other rules can run longer than the IRS periods. Insurers, lenders, landlords and state agencies may expect records for their own purposes, and employment laws set separate periods for personnel and I-9 files. A practical approach many advisers suggest is to keep core financial records for seven years and asset records for as long as the asset plus seven years, but agree the rule with your own adviser and write it down so the agent applies it consistently.
What counts as a record
- Gross receipts: invoices, sales records, deposit records, marketplace and card processor statements, Forms 1099 you receive.
- Purchases and expenses: receipts, bills, cancelled cheques or payment confirmations, and what each was for.
- Assets: purchase documents, improvement costs, depreciation records and sale documents.
- Payroll: wages paid, tax withheld, deposits, Forms W-4, copies of returns filed and W-2s.
- Contractors: Forms W-9 and W-8, agreements, and 1099s issued.
- Supporting documents for decisions: your written bookkeeping rules and the reasons for unusual entries.
IRS Publication 583 says the records you keep should show income, expenses and the basis of assets, and that electronic records are acceptable if they are accurate, accessible and legible. A phone photo of a receipt, filed against the right transaction, is far more useful than the paper original in a drawer.
How an agent keeps the archive in order
- Attach each document to the transaction it supports at the time, not at year end.
- Index by year, type and counterparty so a request from an auditor or lender can be answered quickly.
- Hold a retention date on each record based on the rules you and your adviser set, defaulting to the longer period when unsure.
- Never delete on its own. When a retention date passes, it lists the records for a person to approve disposal.
- Keep an audit trail of every access, change and export.
- Check completeness monthly: transactions over a set amount with no supporting document are listed for you.
The monthly completeness check is where most of the value sits. A missing receipt is easy to get in the week it happened and nearly impossible to get two years later. An agent that lists the gaps every month, while suppliers still have the paperwork, keeps the archive whole without a year-end chase.
Worked example
Example only. A small roofing company in North Carolina is asked by a lender for three years of financial statements and supporting tax returns, and separately receives an IRS letter querying a vehicle deduction from two years ago.
Because receipts, mileage logs and the vehicle purchase documents were filed against transactions when they happened, the agent assembles the lender pack and a separate file for the IRS query in under an hour. The owner sends the IRS file to the company's CPA, who replies to the letter. Nothing had to be searched for in email or boxes. The agent did not reply to the IRS; it prepared the evidence.
The same archive later supports a sale of one of the company's trucks. Because the purchase price, improvements and depreciation were all on file, the CPA works out the gain without estimating any figure.
Common mistakes
- Relying on the bank to keep statements. Banks may not keep them for as long as you need, or may charge to retrieve them.
- Deleting a former software subscription without exporting the data first.
- Keeping receipts with no note of the business purpose.
- Mixing personal and business documents, which makes it hard to produce one without the other.
- Shredding asset records after three years, when the asset is still in use.
Where Pryme fits
On a Pryme Business account, every action by a person or an agent is on the audit trail, and the Finance agent keeps each posting traced to a named source. The Compliance agent can hold retention dates as obligations. Statements are available per currency; see how it works.

Questions people ask
How long should a small business keep tax records?
Generally at least three years after filing, but longer in several cases set out by the IRS, including seven years for bad debt claims and at least four years for employment tax records. Ask your adviser.
Are scanned or photographed receipts acceptable to the IRS?
The IRS accepts electronic records if they are accurate, complete and legible and you can produce them when asked.
Should an AI agent delete old records automatically?
No. It can list records past their retention date, but a person should approve any disposal, after checking that no audit, claim or asset still needs them.
Do state tax agencies have different retention periods?
They can. Check your state revenue department's guidance and keep records for the longer of the federal and state periods.
