🧾 The $75 IRS rule most owners get wrong

Good morning! There is a filing cabinet drawer in every small business in America that functions as a receipt graveyard. Some of you have upgraded to a manila envelope. A few of you are using a Ziploc bag, which, while waterproof, is not what the IRS means by “adequate substantiation.” This week we’re fixing that, because the receipts you can’t find in June are the deductions you lose in April.

This week’s lineup:

The Basics

📚 Receipt management systems that actually work

Most business owners don’t lose deductions because they spent money on the wrong things. They lose them because they can’t prove they spent the money at all.

The IRS calls it “adequate substantiation.” In practice, that means you need five things for every deductible expense: the vendor name, the date, the amount, a description of what you bought, and proof of payment. For meals and entertainment, add who was there and what business was discussed.

That sounds like a lot of paperwork until you realize your phone already does most of it.

A receipt management system doesn’t have to be complicated. It needs three components: a capture method (photo, email forward, or app scan), a storage location (cloud folder, accounting software, or dedicated app), and a categorization habit (tagging expenses by type as they come in, not in a panic the week before your taxes are due).

The simplest version: a dedicated email address that receives forwarded receipts, which auto-files into a Google Drive folder organized by month. The more automated version: an app like Dext or SparkReceipt that scans, extracts, categorizes, and syncs to your accounting software without you typing anything.

The system that works is the one you’ll actually use. If you won’t open an app, use email forwarding. If you won’t forward emails, use a physical inbox that gets scanned once a week. The bar isn’t perfection. It’s consistency.

The IRS gives you a surprising amount of flexibility on format. They accept digital copies, phone photos, and scanned images as valid documentation. What they don’t accept is “I know I bought it, I just can’t find the receipt.”

Build it once. Maintain it weekly. That’s the whole system.

The Strategy

📋 Digital vs. paper receipts — what the IRS accepts as proof

The IRS updated its guidance years ago to accept electronic records, and that change is more significant than most business owners realize. A photo of a receipt taken on your phone carries the same legal weight as the paper original. A PDF emailed from a vendor counts. A screenshot of a digital invoice counts. You do not need to keep the paper.

That said, what qualifies as a “receipt” has specific requirements. The document needs to show the vendor, date, amount, and what was purchased. A credit card statement shows three of those four, but it almost never shows what you actually bought. A $200 charge at an office supply store could be printer cartridges or a personal purchase. The IRS wants the itemized version.

The $75 rule is the one everyone knows and almost everyone misreads. For general business expenses under $75, the IRS doesn’t require a physical receipt. You still need a record — a log entry, a bank statement notation, a note in your expense tracker — but you can skip the paper trail. That changes for two categories regardless of amount: lodging always requires a receipt, and meals under Section 274 always require documentation of who was present and the business purpose discussed.

Here’s what matters in practice: the $75 threshold is not a free pass. It’s a documentation threshold. You still need to prove the expense happened, that it was business-related, and what category it falls under. The receipt requirement just gets lighter below that number.

For anything above $75, keep the itemized receipt. Credit card statements are supporting evidence, not primary documentation. And for anything where the business purpose isn’t obvious from the receipt itself — a restaurant, a retail store, a vague Amazon order — write the purpose on the receipt or log it at the time of purchase. Auditors notice when business purpose annotations show up retroactively in bulk.

The Deep Dive

🔍 Receipt reconstruction — what to do when receipts are lost before an audit

The audit notice arrived. The receipts didn’t survive. This is the scenario that makes business owners lose sleep, and it’s more common than the IRS probably wishes it were.

The good news: the tax code doesn’t require you to have the original receipt in hand to claim a deduction. The Cohan rule, established by a 1930 court case involving Broadway producer George M. Cohan, allows taxpayers to estimate expenses when records are incomplete, as long as there’s a reasonable basis for the estimate. Courts have upheld this principle for decades.

The bad news: “reasonable basis” does real work in that sentence.

Reconstruction starts with the records you do have. Bank statements, credit card records, email confirmations, calendar entries, vendor correspondence — all of these can establish that a transaction occurred, when it occurred, and roughly what it cost. The IRS generally accepts reconstructed records when they’re supported by corroborating evidence from independent sources.

What you’re trying to build is a credible paper trail that shows each expense existed, had a business purpose, and falls within a plausible dollar range. A spreadsheet of round numbers with no supporting documentation doesn’t meet that standard. A credit card statement matched to a calendar entry showing a client meeting at the same restaurant on the same date does.

There are categories where reconstruction is harder. Meals require documentation of attendees and business purpose that almost never exists in bank records. Cash expenses with no digital trail are functionally unrecoverable. And expenses under Section 274 — meals, entertainment, gifts — have strict substantiation rules that the Cohan rule doesn’t override.

The practical advice: don’t wait for an audit to discover your gaps. Run a quarterly self-audit. Pull your bank and credit card statements, match them against your receipt files, and reconstruct anything that’s missing while the details are still fresh. The vendor may still be able to reissue a receipt. Your email may have the confirmation. Your calendar may have the meeting.

The IRS doesn’t expect you to be perfect. But it does expect you to have tried.
