Deducting tools and equipment

In March you bought a $180 impact driver. In July you bought a $30,000 mini excavator. Both are business purchases, both came out of the same account, and the tax return treats them nothing alike.

That is not a mistake. Nearly every legitimate business purchase gets deducted eventually. What the price tag changes is when — all of it this year, or a slice a year while the thing wears out. Knowing which bucket a purchase lands in is most of what a working contractor needs here. The election forms are your preparer's job.

Deducted now or deducted later

Expensed means the whole cost comes off this year's profit. That is how ordinary supplies work: blades, fasteners, a box of drill bits, a $60 pipe wrench.

Capitalized means the purchase is recorded as an asset and deducted over its useful life, a slice each year. That slice is depreciation. Over the full recovery period you deduct the same total dollars — you just wait for most of them. So the choice is about cash flow, not about free money.

Small tools come off in the year you buy them

Hand tools, cordless tools, ladders, jigs, a shop vac, PPE, blades and bits: for most sole proprietors and small LLCs these are simply an expense in the year you buy them. No election, no schedule, no asset ledger. Your preparer usually books them to a "small tools and supplies" line on Schedule C.

No dollar figure in the tax code separates a "tool" from "equipment." Two things push a purchase toward being capitalized: cost, and how long it lasts. A $40 tool that survives ten years is still an expense. A $9,000 machine is not, even if it dies in three.

The safe harbor that ends the argument

The de minimis safe harbor is an election that lets you expense lower-cost items outright instead of judging each one. Elect it, and anything at or under the threshold — measured per item or per invoice — is expensed.

Two things about that threshold. It is not one number: there is a higher limit for businesses with an applicable financial statement (an audited statement, or one filed with the SEC or another federal agency, which almost no small contractor has) and a lower limit for everybody else. You are almost certainly in the lower tier. And that lower limit has already been raised once, and either figure can move again, so do not carry a number over from an old article. The IRS states the current amounts on its tangible property final regulations page.

The election is not automatic. You make it by attaching a statement to a timely filed return, and it rests on a consistent capitalization policy already in place at the start of that tax year. A written policy is required of businesses with an applicable financial statement; the IRS says businesses without one need a consistent procedure existing at the beginning of the year, but not a written one. Writing it down anyway is cheap.

Big equipment: the same cost, three speeds

Say you place a $30,000 machine in service and your preparer classifies it as 5-year property. On the standard schedule, the deduction arrives like this:

Those are the standard 5-year MACRS percentages under the half-year convention. Your asset's recovery period and convention depend on what it is and when it went into service — IRS Publication 946 is the reference, and it is a book for a reason. Treat that schedule as the baseline, not the likely outcome. Two rules can pull the deduction forward.

Section 179 lets you elect to expense qualifying equipment in the year it is placed in service. It carries an annual dollar cap that is inflation-adjusted and has changed repeatedly, a phase-out once total purchases for the year get large, and a ceiling at your business income. The figures for your year are in the Form 4562 instructions — not in an article, including this one.

Bonus depreciation applies automatically to qualifying property unless you elect out, and it has no business-income limit. The percentage is set by legislation and has moved repeatedly: it was 100%, then stepped down year by year, and then 2025 legislation reinstated 100% for qualified property acquired after January 19, 2025 — see Publication 946 and the IRS guidance on the change. Confirm the rate for the year you place the asset in service, not the year you read about it.

Used equipment can qualify for both, which matters if you buy off a dealer lot or at auction — though bonus depreciation on used property has its own conditions, mainly that the machine is new to you and not bought from a related party. Financing does not change the timing either: what counts is the date the machine goes to work, not the date the note is paid off.

Business use is a percentage you have to defend

If a tool is used partly for personal work, only the business share is deductible. Nobody expects a formal log for a $200 miter saw, but a machine you also use on a relative's barn is a split.

The percentage matters more once you accelerate the deduction. Section 179 generally requires more than 50% business use, and if business use later drops below that, part of the deduction can be recaptured — added back to income in the year the use falls. That catches equipment bought for a commercial run that ends.

Vehicles are their own regime. A truck can be capital equipment, but day-to-day driving is usually handled through mileage or actual-cost rules, with separate substantiation. That is a different guide.

What the receipt has to prove

If the deduction is questioned, you are proving three things: that you bought it, what you paid, and that the business uses it. A card statement line reading "HOME DEPOT $1,240" proves one of the three.

Keep the itemized receipt or invoice, in the business name where you can get it. For anything capitalized, keep it for as long as you are depreciating the asset, plus the normal retention window after you sell or scrap it — that final year has a gain or loss calculation in it that needs the original cost. The filing habit in general is its own topic.

Putting the machine's cost back into your prices

A deduction returns a fraction of what you spent. The machine still has to earn the rest back on jobs. Once you know what it has to cover per billable hour or per day, that number has to reach the customer — so keep the equipment charge as a saved line item in DoneQuote instead of re-deriving it on every quote, and the rate you worked out is the rate that goes out. Your saved estimates also show which jobs the machine ran on, which is the same evidence a business-use percentage rests on.

Two dates that decide the year

Buying in December does not by itself buy the deduction. Section 179 and bonus depreciation both run off the date the equipment is placed in service — set up and ready for the work you bought it for. A machine delivered on December 28 and still crated in January is next year's deduction.

The de minimis election runs on an earlier clock. The capitalization policy it rests on has to be in place at the start of the tax year it covers. So ask your preparer about next year's threshold in December, not in April over this year's return.
