The $75 myth: Contractors don't get a receipt-free zone for expenses under $75. That rule applied to employee expense reimbursements — not Schedule C filers. Every deductible expense needs documentation, regardless of amount.
Receipt tracking is the unglamorous backbone of self-employed tax compliance. General contractors, subcontractors, electricians, plumbers, handyman operators — they all face the same problem: business runs on cash payments, job-site purchases, and vendor invoices that are easy to lose and even easier to forget. Then April arrives and the scramble begins.
The scramble costs money. Missing receipts mean missing deductions. And if the IRS ever audits a return with unsubstantiated deductions, the financial hit is far worse than a missed write-off. This guide explains exactly what the IRS requires, how to capture receipts in the field, and the category system that keeps your Schedule C clean year-round.
1. What the IRS Actually Requires (The Real Rules)
The Internal Revenue Code Section 274 requires "adequate records" for business expense deductions. The IRS defines adequate records as documentation that establishes:
- Amount — the exact dollar amount of the expense
- Date — when the expense was incurred
- Vendor or payee — who you paid (business name, not just "Home Depot")
- Business purpose — why this was a legitimate business expense
The receipt itself establishes the first three. The business purpose is your responsibility to note — either on the receipt at the time or in your expense tracking system when you log it.
The $75 myth
The most persistent piece of wrong advice in contractor tax circles is that receipts under $75 don't matter. This misreads the law. The $75 threshold appeared in Treasury Regulations governing employer Accountable Plans — the rules for when employers can reimburse employees tax-free. It has zero application to self-employed contractors filing Schedule C. As a 1099 worker, you need documentation for every expense.
That said, if a receipt genuinely cannot be obtained (a cash payment to a small vendor with no receipt available), a contemporaneous written record created the same day — noting the date, vendor, amount, and business purpose — is an acceptable substitute for receipts under $75. It's a substitute, not an exemption.
For meals specifically
Business meals require two additional data points: who was present and what business was discussed. A receipt that shows $85 at a restaurant doesn't prove it was a business meal. Write the client name and meeting topic on the receipt or in your log immediately. Meals are also only 50% deductible — which is why keeping them in a separate category matters at calculation time.
Capture Receipts in Seconds, Not Hours
ProvExpense lets you photograph receipts on the job site, assign a category, and add a note — all from your phone in under 30 seconds. Your records build themselves as you go.

The IRS has formally accepted electronic records since Revenue Procedure 98-25, reaffirmed in 2011. A clear photograph of a paper receipt, a PDF invoice, or an email order confirmation all qualify as valid documentation — as long as the image is legible and shows all the required information.
What "legible" means in practice
- The receipt image must be sharp enough to read the vendor name, date, and amount clearly
- Thermal paper fades — photograph it immediately and don't rely on the paper copy
- Partial images don't count; capture the entire receipt including the header (vendor name)
- If the back of the receipt has any relevant information (like a credit card summary), photograph that too
Storage requirements
Digital records must be stored in a "durable, accessible" format. Cloud storage (Google Drive, Dropbox, iCloud, or a dedicated expense app) meets this standard — records on a device that can be lost, broken, or stolen do not. Back up your records in at least two places.
Thermal paper tip: Receipts printed on thermal paper (most gas stations, hardware stores, home improvement centers) fade completely within 1–3 years. If an audit happens in year 2 or 3, that paper receipt is gone. Photograph it the day you get it.
3. The Category System: Organize by Schedule C Line
The most useful way to organize contractor receipts is by the Schedule C lines they belong to. At filing time, your receipts need to map directly to tax form lines — so organizing them that way from the start eliminates the year-end sorting nightmare.
| Category | What Goes Here | Deductibility |
|---|---|---|
| Materials & supplies | Lumber, pipe, wire, concrete, fasteners, consumables | 100% |
| Tools & equipment | Hand tools, power tools, testing equipment (under $2,500) | 100% (Section 179) |
| Vehicle / mileage | Business mileage log or actual vehicle expenses | 100% (IRS rate × miles) |
| Subcontractors | Payments to subs (1099-NEC required if >$600) | 100% |
| Insurance | General liability, workers comp, commercial auto | 100% |
| Marketing | Ads, business cards, website, Angi/HomeAdvisor fees | 100% |
| Professional fees | Accountant, attorney, permit expediter | 100% |
| Phone & internet | Monthly bill × business-use percentage | Business % only |
| Office supplies | Paper, ink, postage, small office items | 100% |
| Meals (business) | Client/vendor meals with noted business purpose | 50% only |
| Continuing education | License CE, trade courses, certifications | 100% |
| Licenses & permits | Contractor license renewals, job-specific permits | 100% |
Why meals need their own category: If you mix meals with other supplies, your accounting software can't automatically apply the 50% limitation correctly at year-end. Keeping meals isolated means the calculation is automatic.
4. What to Capture Per Receipt: A Field Checklist
In the field, you don't have time for complex systems. The minimum viable receipt entry takes about 30 seconds:
Receipt checklist (30-second field entry):
✓ Photograph the receipt — full image, sharp, all text visible
✓ Note the category — materials, tools, insurance, meals, etc.
✓ Add a 3-word business purpose — "Bathroom remodel Elm St," "HVAC cert renewal," "Client lunch bid review"
✓ Confirm the date — almost always on the receipt, but verify
That's it. The photograph captures vendor, amount, and date. The category note makes filing automatic. The business purpose note makes the deduction defensible. If you do this at the time of purchase — not at the end of the day, not at the end of the week — your records are complete and contemporaneous by default.
Cash purchases
Cash purchases at supply houses, lumber yards, or tool shops are common in contracting. If the vendor doesn't provide a receipt: write the date, vendor name, amount, and business purpose in a pocket notebook or your phone's notes app immediately. That contemporaneous entry is an acceptable substitute for a receipt under $75. For larger cash purchases, always request a written receipt or invoice — no exceptions.
5. How Long to Keep Contractor Receipts
The IRS standard audit window is 3 years from the return due date or filing date, whichever is later. However, keep records for 6 years as a contractor because:
- If the IRS suspects you omitted more than 25% of gross income, the window extends to 6 years
- State tax agencies may have different (sometimes longer) audit periods
- Business disputes with clients or subcontractors often require records from prior years
For assets you depreciate (vehicles, equipment), keep records for 6 years after the asset is disposed of — because the depreciation recapture rules can affect returns in the year you sell or scrap the asset.
| Record Type | Minimum Retention | Recommended |
|---|---|---|
| General expense receipts | 3 years | 6 years |
| Mileage logs | 3 years | 6 years |
| Equipment purchase records | 3 years after disposal | 6 years after disposal |
| Subcontractor payments / 1099s | 3 years | 6 years |
| Tax returns themselves | 6 years | Indefinitely |

The IRS uses automated scoring (the Discriminant Inventory Function system) to flag returns that statistically deviate from comparable businesses. For contractors, the most common triggers are:
- 100% vehicle business use. Claiming that a vehicle was used exclusively for business is an immediate flag. A realistic allocation (75–90% for a dedicated work truck) is far more defensible.
- High materials costs relative to reported income. If you're claiming $120,000 in materials but only reporting $85,000 in revenue, an auditor will ask where the materials went.
- Large meal deductions. Meals are a known abuse category. Unusually high meal percentages relative to revenue draw scrutiny. Keep them documented and reasonable.
- Round numbers throughout. Claiming exactly $10,000 in supplies, exactly $5,000 in tools, exactly $3,000 in marketing signals estimation rather than actual records.
- Home office deduction inconsistent with business type. A contractor who works on job sites all day claiming a large home office deduction will need to explain when and how the home office is used exclusively for business administrative work.
The protection
Contemporaneous records eliminate virtually all audit risk because you have actual documentation, not estimates. If every expense has a receipt with a business purpose note, there's nothing to dispute — the auditor either accepts it or doesn't, and a well-documented legitimate business expense almost always gets accepted.
7. Subcontractor Payments: The Receipt Problem That Creates Bigger Problems
For general contractors who use subcontractors, receipt tracking has an extra layer. Payments to subcontractors are deductible as a business expense — but if you pay any individual contractor more than $600 in a calendar year, you're required to issue a Form 1099-NEC by January 31 of the following year.
What you need to collect from every subcontractor before paying them:
- Name and address
- Social Security Number or EIN (collected via Form W-9)
- A record of each payment (date, amount, job description)
If you don't collect W-9 information upfront and the sub refuses to provide it later, you may be required to withhold 24% backup withholding from future payments. Collecting the W-9 before the first check avoids this entirely. ProvExpense has a built-in W-9 management module that tracks this for every payee.
W-9 Management Built In
ProvExpense tracks payee information, W-9 status, and total payments per subcontractor — so you know exactly who needs a 1099 at year-end. No January scramble.

The best system is the one you'll actually use on a job site. Here's the minimum viable setup:
- Photograph every receipt immediately. Before you leave the store, before you start the truck, before you pocket the paper. Thermal receipts fade fast — the photo lasts forever.
- Log it the same day. Batch entry at end of day works. Weekly batch entry loses receipts. Monthly batch entry is a disaster waiting to happen. Same-day is the standard.
- Note the business purpose at log time. Not "supplies" — "copper fittings for Johnson bathroom remodel." The specificity is what makes the deduction stick.
- Separate personal and business card spending. A dedicated business credit card creates a clean transaction record that serves as backup documentation. One card for business, one for personal — no exceptions.
- Back up to the cloud monthly. If your system lives only on your phone and the phone gets lost on a job site, your records are gone. Cloud backup is not optional.
- Review categories quarterly. Spend 20 minutes every quarter confirming receipts are in the right categories. Catching a miscategorization in April is much easier than finding it in the middle of a March filing panic.
That system works whether you're a solo handyman or a GC with 15 subs. The discipline is logging each receipt at the time — everything else follows from that.

The contractors who come through audits cleanly aren't doing anything exotic. They have receipts. They have business purpose notes. They have records that were created when the expense happened — not reconstructed later. The entire IRS documentation requirement reduces to: write it down when it happens, save the proof, keep it for six years.
