# What records is a business required to keep for tax and compliance purposes?

Applies to: United States · Updated 2026-09-27

No single federal list exists. The IRS standard requires records sufficient to establish every income, deduction, credit and other figure your returns report, so the core set is whatever proves those figures: receipts including cash, inventory, expenses and each asset's history. Further sets attach only when a trigger applies, each from its own authority: having employees or contractors, making reportable payments, selling taxable goods or services, holding a license, or operating as an LLC, partnership, corporation or nonprofit.

## What does the federal tax standard require your records to show?

The IRS regulation on records, 26 CFR 1.6001-1, requires any person subject to federal income tax, and any person required to file an information return about income, to keep permanent books of account or records, including inventories, sufficient to establish the gross income, deductions, credits and other matters its returns must show. IRS Publication 583 states the consequence: except in a few cases, the law does not require any specific kind of records. Publication 583 does flag specific recordkeeping rules for travel, transportation and gift expenses, referring readers to Publication 463, and specific employment tax records, covered below. What travel, transportation and gift records must contain is a separate substantiation question.

So the test is what your records can prove, not which documents you own: for each figure on each return, you must be able to produce what establishes it. Publication 583 adds that business records must be available at all times for IRS inspection, and that in an examination you may be asked to explain the items reported.

The regulation sets two variations. Individuals whose income comes from the business of farming need for that income only records that let the IRS determine the correct amount subject to tax, not full books. And the IRS may, by notice served on a particular person, require that person to keep specific records.

Accounting software does not mark the edge of the set. Publication 583 says the requirements for paper books and records also apply to electronic storage systems, and that a computerized system must be able to produce sufficient legible records to support and verify entries made on your return and determine your correct tax liability. It adds that you must keep all machine-sensible records and a complete description of the computerized system, including its charts of accounts and controls against unauthorized changes to retained records. The documents that establish those entries, and the agreements, certificates and registrations other authorities require, belong to the set wherever they are kept.

## Which records support income and gross receipts?

Publication 583 says to keep supporting documents that show the amounts and sources of gross receipts, and lists cash register tapes, bank deposit slips, receipt books, invoices, credit card charge slips and Forms 1099-MISC and 1099-NEC among them. Publication 583 also says you need to identify the source of receipts to separate business from nonbusiness receipts and taxable from nontaxable income. Keep the Forms 1099 payers send you with your gross-receipts records when they arrive.

Cash that never reaches a bank account needs its own record. A bank statement shows only what was deposited, so cash spent, kept or paid out before any deposit is documented only by the register tape, receipt book or daily sales record made when it came in. Record every cash sale when it happens, whether or not it is banked.

Large cash receipts also carry a report: the IRS page on Form 8300 says that, generally, a person in a trade or business who receives more than $10,000 in cash in a single transaction or in related transactions must file Form 8300.

## Which records support purchases, expenses and assets?

Publication 583 describes inventory as any item you buy and resell to customers, including a manufacturer's or producer's raw materials and parts, and says its supporting documents should show the amount paid and that it was for inventory. For other costs, Publication 583 says the documents should show the amount paid and that the amount was for a business expense. Which documents prove a particular expense, and when a receipt is required, is a separate question.

Assets need records that outlast the year of purchase. Publication 583 says you must keep records to verify certain information about business assets, because you need them to figure annual depreciation and the gain or loss when you sell. It says those records should show when and how you acquired the asset, the purchase price, the cost of any improvements, any section 179 deduction, deductions taken for depreciation and casualty losses, how you used the asset, when and how you disposed of it, the selling price and the expenses of sale. Of these, the acquisition records (when and how you acquired the asset and what you paid) and improvement costs are what record the asset's cost.

## Which records support figures reported in later years?

Some records arise in one year and support a figure reported in another. They are required for the same reason as this year's receipts: the regulation asks for records sufficient to establish what each return shows, and only these records establish those later figures. Their relevance is set by the position they support, not by their age, so a clear-out of old years destroys exactly the records that cannot be recreated. How long each must be kept is a separate retention question.

The classes to identify are these:

- **Asset history.** Each year's depreciation and the eventual gain or loss rest on the acquisition, improvement and deduction records described above.
- **Owner basis.** The IRS Shareholder's Instructions for Schedule K-1 (Form 1120-S) say a shareholder is responsible for keeping the information needed to figure the basis of their stock, and the IRS Partner's Instructions for Schedule K-1 (Form 1065) make tracking adjusted basis in the partnership the partner's responsibility. The owners keep these, not the business.
- **Carried losses.** The Shareholder's and Partner's Instructions for Schedule K-1 both say losses disallowed by the basis limit can be carried forward, so the loss year's records support each later return that uses the loss.
- **Carried credits.** The IRS Instructions for Form 3800 say unused general business credits may be carried to other years, so the records behind a credit support every return it reaches.
- **Elections.** The IRS Instructions for Form 2553 say an S corporation election, once made, stays in effect until it is terminated or revoked, and list the proof of filing the IRS accepts if it questions whether the form was filed, including an IRS letter stating the election was accepted. An LLC that filed Form 8832 to be treated as a corporation keeps that election's record too, because its IRS classification rests on it.

## What must an employer keep, and what supports each worker's classification?

Having employees adds a separate block of records under agencies of its own, none of which a clean income-tax file satisfies. The main sources are these:

- **Employment taxes.** The IRS page Employment tax recordkeeping lists records including your employer identification number, amounts and dates of all wage payments, employees' names, addresses, Social Security numbers and occupations, copies of withholding certificates such as Form W-4, dates and amounts of tax deposits, copies of returns filed, and documentation for any credits claimed.
- **Wages and hours.** The Department of Labor's Fact Sheet #21 says every covered employer must keep certain records for each non-exempt worker, in no particular form, including hours worked each day, total hours each workweek, the regular hourly pay rate and total wages paid each pay period.
- **Employment eligibility.** USCIS says all U.S. employers must properly complete Form I-9 for every individual they hire for employment in the United States, and tells employers not to file it with USCIS, so it stays in your files.
- **Injuries and illnesses.** OSHA's undated recordkeeping page says many employers with more than 10 employees must keep a record of recordable work-related injuries and illnesses on OSHA's forms or equivalent forms, and that certain industries are exempted.
- **State payroll rules.** Your state may add its own; confirm them from that state's own labor statute or labor department.

Worker classification needs its own file. The IRS page on whether a worker is an independent contractor or employee asks whether the business controls or has the right to control what the worker does and how, whether the payer controls the business aspects of the job, and whether there are written contracts or employee-type benefits, and it tells businesses to document each of the factors used in reaching the determination. The same page warns that classifying an employee as an independent contractor with no reasonable basis may leave you liable for employment taxes for that worker, while a reasonable basis may relieve you of them, but only if you have filed all required federal information returns consistently with treating the worker as a contractor and have treated no worker in a substantially similar position as an employee. That relief, the page adds, does not make the worker a contractor. A contractor label in the ledger is a conclusion; keep the agreement, the facts on control and payment, and a dated note of how you weighed them. This file supports the IRS determination for federal employment taxes; it does not show how the Department of Labor or a state agency would classify the worker.

## What must you collect from others before you pay or sell?

Some required records can only come from someone else, so get them before the payment or sale, while the other party still has reason to provide them.

For payees, Publication 583 says a business that makes payments may have to report them to the IRS on information returns, that Form W-9 is used to get a payee's SSN or EIN, and that if the payee does not provide an identification number you may have to withhold part of the payments as backup withholding. The IRS Instructions for the Requester of Form W-9 say a properly completed and signed Form W-9 can be relied upon to avoid backup withholding to a payee, and give the backup withholding rate as 24% for reportable payments. They add that backup withholding still applies if the IRS notifies you the payee's TIN is incorrect or the payee fails to certify it is not subject to backup withholding. Get the signed form before the first payment. If you pay a payee who has not furnished a TIN, the W-9 instructions say you must withhold 24% of the reportable payment and deposit it with the IRS, or you may become liable for the amount not withheld.

Other records in this class include the employee's withholding certificate and Form I-9, and customers' exemption certificates: New York's Tax Bulletin ST-770, for example, requires you to be able to connect each exempt sale to a particular purchaser and the exemption certificate you have on file.

A W-9 identifies a payee for tax reporting; it does not confirm where the payee's money should go. Before the first payment to any payee, and before paying to changed bank details, confirm the destination through a channel independent of the one the details arrived by: a phone number you already held before the request arrived, such as one in your own record of an earlier confirmation; a number shown on the payee's website at a web address you had on record before the request, never a web address or link taken from the invoice, the request or any message; or one given to you in person. A number, meeting link or video call that reached you through the payee's email or messages, in the same thread or any other, does not count, and neither does a contact number in your own files that was last changed at such a request, because whoever controls that mailbox can answer or join it. Where staffing allows, someone other than the person who entered the details makes the confirmation; a one-person business has no second checker, so the owner confirms personally through the independent route and notes when and with whom. If no such route exists, the change waits: pay only to details confirmed before the change, or by check to an address confirmed before it, until the new details are confirmed in person or through a route you held before the request arrived. Before money moves, compare each payee's amount with that payee's approved invoice or claim, not only the batch total.

## Which records do state, local and licensing authorities require?

Federal categories are not the whole obligation. State tax agencies, local governments and licensing bodies set their own record rules, so no national list exists; you look them up for each state where you register and each license you hold. For each state return you file, keep what establishes its figures and check that state's record rules.

Sales and use tax shows the pattern. In New York, for example, Tax Bulletin ST-770 says a registered vendor must keep records of every sale, the amount of the sale and the sales tax on it; a true copy of each sales slip, invoice, receipt, cash register tape and other original sales document; where no written document is given to the purchaser, a detailed daily record of all cash and credit sales in a daybook or similar journal; and records establishing the taxable status of all purchases. The bulletin warns that if records are inadequate, you may be subject to an estimated audit methodology to determine additional tax due. Other states set their own rules. If you sell taxable goods or services in a state where you are not registered, check with that state's tax agency whether you must register.

Licenses and permits add another layer. The SBA's undated guide Apply for licenses and permits says most small businesses need a combination of licenses and permits from both federal and state agencies, and that what you need from the state, county or city depends on your business activities and location. Any records a license demands come from its issuer, so read each license's conditions rather than tax guidance.

## Which records does your legal form add?

Governance records follow the entity's legal form under its formation state's law. Tax records follow how the IRS classifies it, and Publication 583 says an LLC may be classified as a partnership, a corporation or a disregarded entity. Keep governance records with the business records, not filed away as legal paperwork: they are asked for at a filing, a financing, a sale or an examination. The records by form are these:

- **Sole proprietor.** Publication 583 says the business has no existence apart from you, the owner, so its records are yours and no entity statute adds a governance set.
- **LLC (any number of members, however taxed).** The IRS page on single-member LLCs says a domestic LLC with at least two members is a partnership, and one with a single member a disregarded entity, unless it files Form 8832 and elects to be treated as a corporation; a disregarded LLC's activities should be reflected on its owner's federal tax return, but it is a separate entity for employment tax and certain excise taxes. Publication 583 notes that an LLC is formed under state law, so check that state's LLC statute. Read that statute for the records it requires; an LLC that elects corporate or S corporation treatment also keeps its election proof.
- **Partnership, or LLC taxed as one.** Publication 583 says a partnership must file an annual information return reporting its income, deductions, gains and losses, and each partner keeps the basis records above.
- **Corporation.** Publication 583 says a corporation should keep minutes of board of directors' meetings. The corporation statute of the state where it was formed may set further records rules; read it for them. An S corporation also keeps its election proof, and its shareholders keep their basis records.
- **Tax-exempt organization.** The records regulation, 26 CFR 1.6001-1, requires an organization exempt under section 501(a) to keep, in addition to the books it needs for any unrelated business income tax, permanent books or records sufficient to show specifically its items of gross income, receipts and disbursements, and those required to substantiate the information section 6033 requires. Check its formation state's nonprofit law for governance records.

## How do you strike out the groups that do not apply?

Each group below has its own trigger. Keep the rows whose condition is true for your business and strike the rest.

| Record group | Applies when | Imposed by | What it holds |
|---|---|---|---|
| Core tax records | Always | IRS | Gross receipts including cash, inventory, expenses, asset records, machine-sensible records and system description, if computerized |
| Later-year records | You hold long-lived assets, carried credits, carried losses, elections or an owner's basis | IRS | Asset history, owner basis, credit records, loss records, election proof |
| Payee identification | You make payments you may have to report on information returns | IRS | Signed Forms W-9 and the records behind each information return |
| Employment | You have employees | IRS, Department of Labor, USCIS, OSHA where it applies, your state | Employment tax, wage-and-hour, Form I-9, injury and illness, state payroll records |
| Worker classification | You pay workers you treat as non-employees | IRS | Agreements, facts on control and payment, note of factors weighed, information returns filed for the worker |
| Transaction tax | You sell goods or services a state taxes, or you are registered to collect its sales or use tax | That state's tax agency | That state's sale, tax and exemption records |
| Licenses and permits | Your activity or location requires a license | The issuing federal agency, state, county or city | Whatever the license conditions require |
| Entity and governance | You are an LLC, partnership, corporation or exempt organization | The statute of the state where it was formed; the IRS for an exempt organization | Whatever records that statute lists (read it for them); a corporation's board minutes, which IRS Publication 583 says it should keep; for an exempt organization, the books and records required to substantiate the information section 6033 requires |

For example, a sole proprietor with no employees who pays a freelance designer and sells taxable goods in one state strikes the employment and entity rows. It keeps the core, payee, classification and transaction-tax rows, the later-year row for any equipment, and a license row if its activity or location needs one.

## How do you find which authorities reach your business?

Which authorities reach you depends on the returns you file, where you register, sell or employ, what you do and where you formed the entity, and meeting one authority's requirements does not show that another's are met. Work through each in turn:

1. List every federal return and information return you file; whatever establishes their figures is your core set.
2. If you pay anyone for work, add the employer rows for employees and the classification row for everyone else. Add the payee row for any payment you may have to report on an information return, such as rent or royalties.
3. For each state where you register, collect tax or employ people, start from the IRS State government websites page, which links to each state's information on doing business in the state, taxation and employers, and read that state's tax and labor record rules.
4. For each regulated activity, identify the license issuer, whether a federal agency, the state, or the county or city, and read its conditions. Start from the SBA's licenses and permits guide, which lists federally regulated activities and their issuing agencies and, for state licenses, points to your Secretary of State's website; check county and city rules separately.
5. Read your formation state's entity statute for the records it requires.
