Should I buy equipment before year end?

Buying equipment before year end can accelerate a deduction, but only if the equipment is placed in service, meaning ready and available for use, by December 31, not merely ordered or paid for. Expensing elections let you deduct much of the cost in the first year. The soundest rule is to buy for a genuine business need, letting the deduction follow rather than lead.

Key points

Equipment is deductible in a tax year only if it is placed in service, meaning ready and available for its intended use, by December 31.
Ordering or paying for equipment before year end does not accelerate the deduction if the asset is not installed and usable until January.
First-year expensing under Section 179 and bonus depreciation under Section 168(k) allow much or all of an equipment cost to be deducted immediately.
A deduction returns only a fraction of the purchase price, so equipment bought only for the deduction leaves the business poorer.
Accelerating a purchase helps when this year's income is higher than next year's, and waiting helps when next year's income will be higher.

How does the placed-in-service rule work?

The single most important technicality is the placed-in-service rule, and it trips up owners every year. To deduct equipment in a given year, the equipment must be placed in service by the end of that year, meaning it is ready and available for its intended use, not merely ordered, paid for, or sitting in a crate. A machine delivered on December 30 but not set up and operational until January is a next-year deduction, regardless of when you paid.

A year-end purchase only accelerates the deduction if the asset is actually in service by December 31. If you are buying late in the year for the deduction, plan the delivery and installation so the asset is usable before the year closes, and keep the delivery and installation records that show the date.

What lets me deduct the whole cost in the first year?

Ordinarily equipment is depreciated over several years on Form 4562. Two provisions allow much of the cost, and in some cases all of it, to be deducted in the year the asset is placed in service. The Section 179 election lets a business expense qualifying property up to an annual limit that phases out for businesses placing very large amounts in service, and it cannot create a loss. Bonus depreciation under Section 168(k) applies automatically unless the business elects out, and it can produce a loss.

The One Big Beautiful Bill Act (P.L. 119-21, signed July 4, 2025) modified both provisions, so confirm the current first-year expensing rules with your CPA before assuming how much a year-end purchase will deduct. The concept, deducting a large share up front, is the reason timing the purchase matters at all.

When does accelerating the purchase help?

The year-end equipment question is really a timing question. If your income is high this year and you need the equipment anyway, accelerating the purchase and its deduction into this year reduces this year's tax. If you expect higher income next year, the opposite may be true, and it can be better to wait so the deduction lands against income taxed at a higher rate. The lever works in both directions, which is why the decision should follow your income projection rather than a reflex to spend before December.

Plan equipment purchases as part of a year-end review with your CPA: list what the business actually needs, compare which year the deduction is worth more, and if buying late in the year, make certain the asset is placed in service before December 31.

When is buying before year end not worth it?

Buy for the business need, not for the deduction. A deduction returns only a fraction of what you spend; the rest is still money out the door. Buying equipment you do not need in order to capture a deduction leaves you poorer, because you have spent real dollars to save a portion of them in tax.

Financing changes nothing about this arithmetic: a financed purchase placed in service still qualifies for first-year expensing, but the loan payments continue long after the deduction has been used. Accelerating deductions into a low-income year also wastes them against income that would have been taxed lightly anyway, and a Section 179 deduction limited by business income simply carries forward. An owner whose income is flat from year to year gains little from timing and should buy when the equipment is needed.
