The de minimis safe harbor is an annual election under Treas. Reg. Section 1.263(a)-1(f) that lets a business deduct small equipment and property purchases immediately as expenses instead of capitalizing them and depreciating them over several years. It is available to any business, from a Schedule C freelancer to a corporation, and it is the simplest of the three expensing tools, sitting alongside Section 179 and bonus depreciation. Its real product is certainty: items under the threshold are supplies by rule, and the IRS has agreed in advance not to argue about it.
The $2,500 and $5,000 thresholds and how the election works
The threshold depends on whether the business has an applicable financial statement (AFS), which in practice means audited financials or SEC filings. Without an AFS, which describes nearly every small business, items costing up to $2,500 per item or per invoice can be expensed. With an AFS, the threshold is $5,000. The $2,500 figure comes from IRS Notice 2015-82 and has been fixed since 2016; it is not indexed for inflation. Additional costs on the same invoice, such as delivery and installation, count toward the per-item price.
Three requirements make the election stick. The business must have accounting procedures in place at the beginning of the year treating items under its chosen threshold as expenses; a written policy is mandatory for AFS businesses and strongly recommended for everyone else. The business must actually expense those items on its books during the year. And the return must carry a short statement titled "Section 1.263(a)-1(f) de minimis safe harbor election" with the taxpayer's name, address, and identification number, attached to a timely filed original return. The election is annual, not permanent, and once made it covers every qualifying item that year; you cannot cherry-pick.
The safe harbor is not a ceiling on deductions. An item over the threshold can still be written off in full through Section 179 or 100% bonus depreciation. What the safe harbor adds is procedure: items under the line never touch Form 4562, never sit on a depreciation schedule, never generate depreciation recapture, and cannot be recharacterized as capital assets on audit.
2026 figures
For 2026 the thresholds remain $2,500 per item or invoice without an AFS and $5,000 with one, both unchanged since Notice 2015-82 took effect in 2016. Two neighboring rules frame it. Items costing $200 or less, or with an economic useful life of 12 months or less, are deductible as materials and supplies even without the election. And with bonus depreciation restored to 100% permanently for property acquired after January 19, 2025, the cash difference between the safe harbor and capitalizing-then-bonus-depreciating is now small; the difference that remains is procedural, covering depreciation schedules, recapture on later sales, and state conformity.
For creators and the self-employed
This is the rule that covers most of a creator's gear: lenses, microphones, drones, monitors, lights, hard drives, phones, and most laptops come in under $2,500 apiece. With the election in place, those purchases are deducted as supplies on Schedule C rather than run through Form 4562, and because they reduce net profit before Schedule SE, they cut both income tax and 15.3% self-employment tax in the year of purchase. S corporations and partnerships make the election at the entity level on Form 1120-S or Form 1065, and the deduction reaches the owner through the Schedule K-1.
The per-item, per-invoice mechanics reward attention at checkout. An invoice listing eight cameras at $2,100 each qualifies item by item, all $16,800 of it. A single $6,000 cinema camera does not, and it should be expensed through Section 179 or bonus depreciation instead. Keep the invoices themselves: the election statement is short, but the consistency requirement means your books must actually expense these items all year, and the receipt trail is what proves each item's price sat under the line.
Mistakes that cost money
First, skipping the election statement. The safe harbor is elective, and without the attached statement the protection does not exist; on audit the IRS can recharacterize expensed items as capital assets, move deductions into later years, and add accuracy penalties. Second, splitting invoices to sneak under the threshold. Asking a vendor to bill a $4,800 workstation as two $2,400 invoices is the exact manipulation the regulation anticipates, and it forfeits the safe harbor for those items. Third, applying it to inventory. Property held for sale to customers is inventory and is never eligible; a reseller expensing product purchases this way is misstating cost of goods sold. Fourth, missing that the test is per item. A $10,000 order of four $2,500 chairs qualifies in full, while a single $2,600 chair fails; taxpayers who apply the threshold to the order total get it wrong in both directions. Fifth, expecting capital gain when the gear sells. Because safe harbor items were never capital assets, selling used equipment later produces ordinary income, and those sales are reportable even when the original cost was fully deducted.
Coordinating with Section 179 and bonus depreciation
A sensible small-business stack for a year of purchases: everything at or under $2,500 rides the de minimis election as supplies; larger items take 100% bonus depreciation or Section 179 on Form 4562; and anything the owner wants to spread out, usually to preserve deductions for higher-bracket years, is elected out of bonus and left on the regular MACRS schedule. The safe harbor election, once attached, costs nothing in flexibility because it only sweeps up the small items that were never worth a depreciation schedule in the first place.
If your purchases cluster near the threshold, you resell hardware, or you are unsure whether your bookkeeping policy qualifies, have a professional set the written policy and the election language before year end; this is a rule where a two-paragraph document decides the audit.
