The de minimis safe harbor lets you expense any item up to $2,500 ($5,000 with audited financials) instead of capitalizing it. The written-policy requirement, the election, and why it still matters.
The de minimis safe harbor lets you deduct — immediately, as an ordinary expense — any item costing up to $2,500, instead of putting it on your books as an asset and depreciating it. The limit applies per item or per invoice, and it rises to $5,000 if your business has audited financial statements. Buy ten laptops at $1,800 each? All $18,000 is expensed the day you buy them, no depreciation schedule, no asset ledger entries.
Two strings are attached: you need an expensing policy in place at the start of the year, and you attach a short annual election statement to your return. This post covers the mechanics — and answers the obvious question of why the safe harbor still matters now that 100% bonus depreciation is permanent, a topic our bonus depreciation and Section 179 playbook covers in full.
The $2,500 ceiling applies to businesses without an applicable financial statement — which is most small businesses. With audited financials (or certain SEC/government filings), the ceiling is $5,000. Costs like delivery and installation billed on the same invoice count toward the item's cost; test the all-in number.
The threshold is applied item by item, not to the invoice total. Ten laptops at $1,800 each on one $18,000 invoice: every laptop passes the test individually, so the whole $18,000 is expensed. The same goes for desks, phones, tools, small machinery, and software. What fails: a single $6,000 server. That one gets capitalized — and then almost certainly written off anyway under bonus depreciation or Section 179.
One caution: don't carve a genuinely single asset into parts to sneak under the threshold. A $7,500 machine invoiced as three "components" you bolted together is one asset. The safe harbor covers things that are actually separate items.
Fair question. With 100% bonus depreciation permanent for property acquired after January 19, 2025, and Section 179's limit at $2,560,000 for 2026, a laptop gets fully written off in year one under any of the three methods. The safe harbor still earns its keep:
The practical playbook: de minimis for everything at or under $2,500, bonus or Section 179 for the big stuff — vehicles (including heavy ones under the 6,000-pound vehicle rules), machinery, and major build-outs.
For the safe harbor to hold up, your expensing policy must exist at the beginning of the tax year — you can't adopt it in December and apply it to March purchases. For a business without audited financials, the policy doesn't technically have to be written, but a written one is trivial to create and ends the argument. One paragraph: "Effective January 1, [year], [Company] expenses for book and tax purposes all property costing $2,500 or less per item or invoice." Date it, keep it with your records, and actually book purchases consistently with it. Then remember the second half: the election statement goes on the return every year — it's annual, not one-and-done.
Two pieces of paper — a dated policy before year-start and a yearly election on the return — buy you a lifetime of not tracking small assets.
The safe harbor lives inside the broader repair regulations, which govern a related question: when you spend money on property you already own, is it a deductible repair or a capitalized improvement? Broadly, costs that keep an asset in ordinary operating condition — patching a roof section, servicing equipment, repainting — are repairs, deductible now. Costs that better the asset, restore it after it's worn out, or adapt it to a new use — replacing the entire roof, rebuilding an engine, converting a garage to an office — are improvements, capitalized and depreciated. Small-dollar spending under your de minimis threshold sidesteps the whole analysis, which is one more quiet benefit of the election.
This is fundamentally a bookkeeping habit: a policy on file, a consistent expense account for sub-threshold purchases, and a checkbox at tax time for the election. If your chart of accounts dumps everything into "equipment," you're either capitalizing things you didn't need to or expensing things inconsistently — both create cleanup work later.
New businesses should adopt the policy on day one. Equipment you buy for a business that's up and running is never a Section 195 startup cost — it's expensed or depreciated once placed in service — so a de minimis policy from the start keeps your launch-phase laptops and furniture off both the amortization schedule and the asset register. Our guide to deducting startup costs under the $5,000 first-year rule covers where the pre-opening spending goes.
The de minimis safe harbor turns every purchase up to $2,500 per item ($5,000 with audited financials) into a simple, immediate expense — no depreciation schedules, no recapture, no state add-back headaches — as long as your policy predates the year and you make the annual election on the return. It's the low-drama companion to bonus depreciation and Section 179.
