Should You Make a Major Business Purchase Before the Year Ends?

Every December, the same conversation comes up. A business owner looks at the year’s profit, sees a larger tax bill than expected, and wonders whether buying that truck or machine now would help.



Sometimes it does. Sometimes it just trades a tax bill for a cash problem. The difference comes down to three things: whether you actually need the asset, whether you can afford it, and whether it will qualify for a deduction this year.

How a Year-End Purchase Can Lower Your Taxes

Normally, you deduct the cost of equipment a little at a time over several years. Two provisions let you speed that up.

Section 179 lets you deduct the full cost of qualifying equipment in the year it goes into service. There are dollar limits and income restrictions. It covers things like machinery, computers, office equipment, and some vehicles.



Bonus depreciation lets you write off a set percentage of an asset’s cost in the first year. Under current federal law, that’s 100% for qualifying property acquired after January 19, 2025, as long as it’s placed in service in that tax year.

Whether you qualify depends on the type of asset, when you acquired it, how much you use it for business, and the specific rules that apply. Paying before December 31 doesn’t automatically earn you a full deduction.

Do You Actually Need It?

A deduction is a nice bonus, but it shouldn’t be the reason you buy something.



Start with what the asset will do for the business. A new machine might raise your output. A software and hardware refresh might save your team hours each week. A newer van might cut repair bills or let you add a service route. If you can point to a result like that, the purchase has a clear business purpose.

Timing matters too. Equipment that adds capacity or cuts costs right away may be worth buying now. An upgrade that’s merely nice to have can usually wait until next year without much harm.

What It Does to Your Cash

This is where owners most often go wrong. A deduction doesn’t give you the purchase price back. It lowers your taxable income, so your tax bill drops by some fraction of the amount, depending on your tax rate and overall situation.



Say you spend $50,000 on qualifying equipment. You don’t get $50,000 back. You may get to deduct that amount, and the savings are whatever that deduction does to your tax bill.

Before you commit, look at your cash on hand and what’s coming due: payroll, vendor bills, loan payments, and your working capital needs. If you’re financing the purchase, factor in the monthly payments and interest as well. A deal that leaves you short on cash in the first quarter can easily cost more than the tax savings were worth.

The December 31 Trap

For depreciation, the asset generally has to be placed in service during the tax year. That means it’s ready and available to use, not just ordered or paid for.



A signed contract in December doesn’t do it. Neither does a deposit, or even a paid invoice. What matters is whether the equipment is ready to run. Say a CNC machine is delivered on December 18, but the installers can’t finish setup and test runs until January 6. For tax purposes, it probably went into service in the new year, and the deduction goes with it.

So before you count on anything, get real dates from your vendor. When does it arrive? How long will installation take? Will it be working by the 31st? Also confirm that the business owns the equipment and that you’ll use it mainly for business.

Is Taking the Deduction Now the Best Move?

Faster isn’t always better. If you expect much higher income next year, spreading deductions out may serve you better than using them all up now.



There’s no single right answer. If this year was strong and next year looks slower, taking the deduction now usually makes sense. If it’s the reverse, waiting may be better, since a deduction is worth more against higher income. Entity type and other deductions you already have matter too.

The easiest way to decide is to run the numbers twice, once with the purchase this year and once next year, and compare taxable income, cash flow, and next year’s tax bill side by side.

Look at the Bigger Picture

A large purchase shouldn’t be decided in isolation. Weigh it alongside your projected profit, your own compensation, retirement contributions, available credits, and any other investments you’re planning.

At Straight Talk CPAs, we work through these decisions with business owners throughout the year, not just in December. We look at where your finances stand today and where you want the business to go, then find the tax savings that fit.

A big purchase can be a smart move when the business needs it and the numbers work. Talk it through with a CPA before you sign anything. The best year-end purchase is one that makes your business stronger and also happens to reduce your tax bill.
