Which Expenses Require Receipts? IRS Rules

Your bank balance can show that money left your account. It cannot show why it left, whether it was ordinary and necessary for your business, or whether it survives an IRS question two years from now. That is the real answer behind which expenses require receipts: receipts are evidence, not just paperwork.

For US freelancers and companies of one, the IRS does not offer a single clean rule that says, “Keep receipts over this amount and ignore the rest.” The familiar $75 threshold matters, but it is not permission to run a business without records. A receipt is only one piece of substantiation. You also need a record that connects the purchase to your work.

Which Expenses Require Receipts Under IRS Rules?

The safest operating rule is simple: keep proof for every deductible business expense, regardless of amount. A digital receipt, invoice, order confirmation, or vendor email is usually enough when it shows what was bought, when, from whom, and how much.

The IRS generally requires documentary evidence for business expenses of $75 or more. But there are important exceptions. You should retain a receipt for lodging even when the cost is below $75. And for many expenses under $75, you still need your own contemporaneous record showing the amount, date, place or vendor, and business purpose.

That means a $12 stock-photo purchase may not need a formal receipt under the $75 documentation threshold, but “Adobe charge” on a credit-card statement is weak evidence. Was it a business image license? A personal subscription? A reimbursable client cost? Your record needs to answer that without relying on memory.

The $75 rule is best understood as a narrow documentation exception, not a bookkeeping strategy. Receipts are cheap to capture when the purchase happens. Reconstructing a year of transactions during tax season is expensive in time, focus, and confidence.

Expenses Where a Receipt Is Especially Important

Some categories are routinely scrutinized because personal and business use often overlap. Treat receipts and supporting notes as non-negotiable here.

Travel and lodging

Keep receipts for airfare, hotels, rental cars, baggage fees, conference registration, and other travel purchases. For lodging, retain the itemized hotel folio regardless of cost. It identifies the dates, location, and charges in a way a card statement does not.

Also record the business reason for the trip. “Client workshop in Chicago” is useful. “Travel” is not. If a trip includes personal days, separate them honestly. A business trip does not turn every meal, museum ticket, or extra night into a deduction.

Business meals

A restaurant receipt establishes the amount and venue, but it does not establish the business purpose. Add a note with the date, who attended, their business relationship to you, and what was discussed. For example: “Lunch with design client, reviewed Q3 product launch scope.”

Most qualifying business meals are generally subject to a 50% deduction limit. The receipt still matters even when the amount is small, because meals are easy to misclassify and hard to explain after the fact.

Equipment, software, and supplies

Keep purchase records for computers, cameras, monitors, phones, tools, office furniture, and other equipment. These purchases may be deducted immediately, depreciated over time, or handled under other tax rules depending on the asset and your tax situation. The receipt establishes cost and purchase date, both of which matter beyond the current year.

For software, retain renewal confirmations and invoices. A monthly editing app, scheduling tool, domain renewal, or AI service can look like an anonymous card charge six months later. The invoice supplies the missing context.

Advertising, contractors, and professional services

Save invoices for ads, sponsorships, web hosting, legal work, bookkeeping, design, and subcontractor payments. For contractors, an invoice alone is not the whole file. Keep the agreement, the invoice, and proof of payment.

If you pay qualifying US contractors $2,000 or more during the year ($600 for payments made before 2026, per the IRS 1099-NEC instructions), you may have information-reporting obligations, including collecting a Form W-9 and potentially issuing a Form 1099-NEC. That is separate from receipt retention, but it is the same discipline: know who was paid, what they did, and why the payment was business-related.

A Card Statement Is Not a Receipt

Bank and credit-card statements are valuable backup records. They confirm that money moved. Usually, they do not prove what was purchased or why it was deductible.

A statement line reading “APPLE.COM/BILL $29.99” could be cloud storage, a personal app, a client project tool, or a family subscription. A transaction record without context creates ambiguity, and ambiguity is where deductions become vulnerable.

Use statements to reconcile your records, not as your only records. The stronger file combines the merchant document, payment evidence, and a short business-purpose note when the purpose is not obvious.

Mileage Does Not Work Like Other Expenses

If you use the standard mileage method, you do not need gas receipts to substantiate the mileage deduction. You need a timely mileage log. That log should show the date, destination, business purpose, and number of business miles for each trip.

“Drove 42 miles” is incomplete. “42 miles round trip to meet Acme Studio about website redesign” is defensible. Parking fees and tolls related to business driving can generally be tracked separately, so keep those receipts too.

If you use the actual-expense method instead, receipts for fuel, repairs, insurance, registration, and other vehicle costs become central. You must also track business versus personal use. You cannot claim 100% of a mixed-use vehicle’s actual costs simply because you sometimes drive it to client meetings.

Home Office, Phone, and Mixed-Use Costs

The home office deduction is another category where the supporting records matter more than a single receipt. Keep rent or mortgage-interest records, utility bills, insurance documents, and measurements supporting the business-use portion of your home. The space must generally be used regularly and exclusively for business, subject to the applicable rules.

For a phone or internet plan used for both work and personal life, keep the bill and document a reasonable business-use percentage. Do not invent a precise-looking number you cannot explain. If 60% reflects how you actually use your phone for client calls, project management, and work messages, record that rationale and apply it consistently.

The same principle applies to shared software, a personal car, and a computer used for both business and home. The tax deduction is for the business portion, not the entire bill.

A Receipt Capture Habit That Holds Up

The most reliable workflow happens at the point of purchase. Capture the receipt, assign a category, and add a short note before the details evaporate. Waiting until month-end is better than waiting until tax season, but immediate capture wins because the business reason is still obvious.

For every expense, aim to preserve five facts: the vendor, date, amount, item or service purchased, and business purpose. Add payment evidence where useful. Store digital records in a format you can retrieve by tax year and category.

Paper receipts fade. Email inboxes become archaeological sites. A local-first receipt workflow gives you the practical advantage of having the record on the device where you run the business, without forwarding readable purchase data to another cloud account. Keel uses on-device receipt capture so the receipt, extracted details, and your business note stay on your iPhone. Nothing readable leaves the phone.

This is not about collecting screenshots for their own sake. It is about producing one honest number for each expense and the evidence behind it.

How Long Should You Keep Receipts?

For many federal tax situations, keeping records for at least three years after filing the return is a common baseline. But longer retention can be wise. The IRS can have more time in cases involving substantial underreporting, and records connected to property or equipment may be needed until years after you dispose of the asset.

As a practical approach, retain expense records for at least three years after filing, keep asset and depreciation records for the life of the asset plus the relevant retention period, and check whether your state has a longer requirement. If you are unsure, ask a tax professional who understands your business structure and location.

The point is not to build a private archive nobody can use. It is to make every real business expense easy to find, easy to explain, and hard to dispute when the year is no longer fresh in your mind.
