De Minimis Safe Harbor: Expense Small Purchases
The annual election to deduct items under the per-invoice threshold instead of depreciating them — who qualifies and how to elect
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
The de minimis safe harbor is an annual election under the tangible property regulations that lets a business deduct low-value items — tools, small equipment, furniture, computers — in the year paid instead of depreciating them. The threshold is US$2,500 per invoice or item for businesses without an audited financial statement, and US$5,000 for those with one.

What does the safe harbor do?
Without it, every asset with a useful life beyond the year is technically a capital expenditure to be depreciated — including a US$180 drill or a US$900 laptop. Section 179 and bonus depreciation can write those off in year one, but only by listing each item on Form 4562 as an asset. The de minimis safe harbor bypasses the asset accounting altogether: qualifying items are treated as ordinary supplies expenses, not as depreciable property, so they never appear on the fixed asset schedule, never create recapture, and never affect the section 179 limit or the mid-quarter convention test.
What are the thresholds?
| Taxpayer | Threshold | Condition |
|---|---|---|
| Without an applicable financial statement (most small businesses) | US$2,500 per invoice, or per item as substantiated by the invoice | Written or consistently applied accounting procedure to expense such amounts, in place at the start of the year |
| With an applicable financial statement (audited statements, or statements filed with the SEC or a government agency) | US$5,000 per invoice or item | Written accounting procedure in place at the start of the year, followed for book purposes |
"Per invoice or per item" means a US$7,000 invoice for four US$1,750 chairs qualifies item by item if the invoice shows the per-item cost, but a single US$3,000 machine does not qualify at any part. Additional costs on the same invoice (delivery, installation) are included in the item's cost (allocated among the items when there are several); costs billed on a separate invoice need not be. The thresholds are ceilings on the safe harbor, not on deductibility — an item over the threshold may still be deducted through section 179 or bonus depreciation, just as an asset.
How do I make the election?
By attaching a statement titled "Section 1.263(a)-1(f) de minimis safe harbor election" to a timely filed original return (including extensions) each year, with the taxpayer's name, address, taxpayer identification number, and a statement that the election is being made. It is an annual election — it must be attached every year it is used — and it applies to all qualifying amounts paid during the year (it is not asset by asset). Once made for a year, it is irrevocable for that year. There is no Form 3115 or method change involved; the election is itself the authority.
The non-AFS taxpayer's "accounting procedure" need not be written, but must be consistently applied — the business actually expenses these items on its books. Most small businesses' bookkeeping already does this; the election simply gives it tax authority.
What does it not cover?
Inventory (items held for sale), land, and rotable, temporary, or standby emergency spare parts that the business capitalizes or accounts for under the optional method are outside the safe harbor. Qualifying amounts are not capitalized even when they would otherwise be improvements — the regulations bar an electing business from capitalizing them — but the per-invoice or per-item ceiling still governs, so a larger building project remains a repair-or-improvement question under the tangible property regulations' separate tests. And it applies to what is paid, not what is placed in service, so a cash-method business dates the deduction to payment.
Why does it matter for small businesses?
Nearly every trade guide on this site cites the de minimis election because it is the tool that keeps hand tools, cables, chairs, monitors, treats, leashes, and test kits off the depreciation schedule. A contractor buying US$8,000 of tools across thirty invoices deducts all of it as supplies with one election statement, instead of thirty assets on Form 4562 — and when a tool is lost or sold, there is no basis to track and no recapture to compute — sale proceeds are simply ordinary income. The fixed asset schedule then holds only the items over the threshold: the van, the CNC, the jetter.
Worked example
An electrical contractor without audited statements spends US$11,400 during the year on meters (US$620 each), a knockout set (US$1,850), ladders (US$390 to US$740), cordless tool kits (US$1,200 to US$2,300), and a hydraulic bender (US$4,100). With the election statement attached to the return, every item except the bender is deducted as supplies — US$7,300 in total. The bender exceeds the US$2,500 threshold and goes on the fixed asset schedule as 7-year property, expensed under section 179. Had the contractor bought the bender and two US$2,400 cable pullers on one US$8,900 invoice with the per-item prices shown, the pullers would qualify item by item and only the bender would be capitalized.
Frequently asked questions
What is the de minimis safe harbor?
An annual election under the tangible property regulations to deduct amounts paid for tangible property up to a per-invoice or per-item threshold as expenses in the year paid, rather than capitalizing and depreciating them.
What is the threshold without an audited financial statement?
US$2,500 per invoice or per item. Businesses with an applicable financial statement may use US$5,000.
How do I make the election?
Attach a statement to a timely filed return each year identifying the taxpayer and stating that the section 1.263(a)-1(f) de minimis safe harbor election is being made. It applies to all qualifying amounts for that year.
Does it apply per item or per invoice?
Either: the threshold is tested against the invoice total or, where the invoice itemizes costs, against each item.
