Receipts matter because they support the numbers reported on a tax return. But a receipt by itself is not always enough. The file should also explain the business purpose and how the expense fits the business.
Quick answer
Keep receipts, invoices, paid bills, statements, deposit records, canceled checks, mileage logs, and business-purpose notes. The IRS says a business recordkeeping system should clearly show income and expenses, and supporting documents should be kept in an orderly and safe place.
What receipts prove
Receipts usually show vendor, date, items, tax, and amount. They may not show business purpose, personal-use split, reimbursement, or customer/job connection. Add those notes before filing.
For a useful business record, make sure the document can show the payee or vendor, amount paid, date, item or service description, and proof of payment. If the receipt does not explain the business reason, add a note while the context is still fresh.
Supporting business documents
The IRS lists supporting documents such as sales slips, paid bills, invoices, receipts, deposit slips, and canceled checks. Gross receipts, purchases, expenses, assets, and employment taxes each need their own supporting records.
Credit card statements and bank statements help prove payment, but they may not prove what was purchased. An invoice may show what was purchased but not whether it was paid. Strong files often keep both.
The under-$75 myth
Do not assume a small purchase is automatically safe without proof. Some travel and expense substantiation rules are narrow, but a self-employed business should still keep records for deductible expenses. The safer workflow is simple: if you want to claim it, save proof or rebuild reliable alternative documentation.
Meal and travel receipts
Meal and travel records need more than the restaurant or hotel name. Add who was involved, the business purpose, the event or client, and whether any part was personal. Keep airfare, lodging, rideshare, rental car, parking, toll, conference, and meal records in the travel month.
Digital vs paper records
Electronic records can work when they are complete, accurate, accessible, and organized. Scan or photograph receipts while the details are readable. Keep backups and avoid relying on one app inbox or one email account.
Mileage logs and receipts
Mileage records are separate from receipts. A business trip log should show date, distance, destination or route, purpose, and vehicle. Save tolls, parking, charging, fuel, and repairs separately.
How long to keep records
The IRS says records should generally be kept as long as needed to prove income, deductions, or credits, with specific limitation periods depending on the situation. Employment tax records should be kept for at least four years. Keep property records longer when they support basis, depreciation, or sale calculations.
For US records, the common three-year period is only a baseline. Longer periods can apply when a return is amended, a bad debt or worthless securities claim is involved, income is substantially omitted, no return is filed, or fraud is involved. Canada commonly requires business records to be kept for six years from the end of the relevant tax year unless permission is granted to destroy them earlier.
Lost receipt workflow
If a receipt is missing, look for a duplicate from the vendor, card statement, invoice, email, calendar record, mileage log, customer message, or photo. Add a note explaining what happened. Do not create unsupported numbers.
Receipt quality checklist
A useful receipt shows who was paid, when the payment happened, what was purchased, how much was paid, and any tax or tip included. A useful business record also explains why the purchase was business-related. For example, “lunch” is weak. “Client meeting with ABC Plumbing to discuss April proposal” is stronger.
Records by category
Gross receipts need sales slips, invoices, deposit records, processor statements, 1099 forms, and bank records. Purchases need invoices, receipts, order confirmations, and payment records. Expenses need bills, statements, receipts, and business-purpose notes. Assets need purchase records, placed-in-service dates, depreciation details, sale records, and business-use percentage where relevant.
Digital record habits
Use a consistent file name such as YYYY-MM-DD vendor amount category. Store the image or PDF in the correct tax-year folder. Keep backups outside the phone camera roll. A receipt saved only in a messaging app, glove box, or email inbox is easy to lose.
What an IRS-style record should answer
The record should let someone understand the transaction without asking you months later. What was bought? Why was it for the business? Was any part personal? Was it reimbursed? How was it paid? Which income activity does it relate to?
Canada and Europe note
CRA and European tax authorities use different systems, but the same discipline helps: original documents, income records, expense records, vehicle records, invoices, and retention periods matter. VAT/GST invoices can require specific details, so businesses should keep the full invoice rather than only a card statement.
Simple standard for every receipt
Use the “future reader” test. If someone opened the receipt folder next year, could they understand the expense without calling you? If not, add a note now. The note can be short: client name, project, route, business purpose, personal-use split, or reimbursement status. The receipt proves the transaction; the note explains why the transaction belongs in the business file.
FAQ
Does the IRS require every receipt for self-employed expenses?
The IRS expects records that support income and expenses. Receipts are usually the easiest proof, but other documents can also support a transaction when they clearly show the facts.
Are digital receipts acceptable?
Digital records can work if they are legible, complete, organized, and accessible. Keep backups and avoid storing the only copy in a phone photo roll.
How long should self-employed people keep receipts?
Keep records for as long as they may be needed. Many US taxpayers use at least three years as a baseline, but longer periods can apply. Canada commonly uses six years from the end of the relevant tax year.
What should I do if I lose a receipt?
Request a duplicate, search email and vendor portals, match the payment to bank records, and write a short business-purpose note. If the proof is still weak, flag the expense for review.
