Summary of Key Points
- Section 179 and bonus depreciation both let a business deduct the cost of equipment immediately
- Equipment must be placed in service, not just purchased or ordered, before Dec 31 to qualify for a deduction in the current year.
- Section 179 is limited by business taxable income and an annual purchase cap, while bonus depreciation has no income limitation.
- North Carolina does not conform to federal bonus depreciation and requires most of the deduction to be added back and recovered over several years.

Equipment purchases are one of the most straightforward ways for a business to lower its tax bill, and also one of thEquipment purchases are one of the most straightforward ways for a business to lower its tax bill, and also one of the easiest to mistime. Wait until December to start thinking it through, and lead times alone can put the deduction out of reach no matter what the tax code allows.
Section 179 and bonus depreciation both let a business deduct the cost of qualifying equipment in the year it is put to use, rather than spreading that deduction over several years.
How Section 179 and Bonus Depreciation Work Together
Section 179 lets a business elect to expense the full cost of qualifying equipment, up to an annual limit, in the year it is purchased and placed in service, rather than depreciating it over time. The election applies asset by asset, and the deduction cannot exceed the business’s taxable income for the year, so Section 179 cannot be used to create or increase a loss.
Bonus depreciation works differently. It currently allows businesses to deduct 100 percent of the cost of qualifying new or used property in the year it is placed in service, with no income limitation. Unlike Section 179, bonus depreciation can create or add to a net operating loss, which makes it useful for businesses whose income varies from year to year.
Why the Placed-in-Service Date Is the Detail That Trips People Up
A purchase order or an invoice date is not what determines when a deduction is available. What matters is when the equipment is placed in service, meaning it is installed, operational, and ready for its intended use in the business.
Equipment ordered in November that does not arrive, get installed, and become operational until January belongs to next year’s tax return, not this one, regardless of when the purchase order was signed or the deposit was paid. This is one of the most common surprises at year-end, particularly for machinery, specialized equipment, and technology systems that require setup time after delivery.
Working backward from Dec 31, rather than forward from the purchase decision, is the safer way to plan. Our Charlotte tax preparation team can help you confirm whether a planned purchase will actually be placed in service in time to count for the current year.
North Carolina’s Treatment of Bonus Depreciation
North Carolina does not follow the federal bonus depreciation rules. Instead, the state generally requires most of that deduction to be added back to income in the year it is claimed, then allows it to be recovered gradually over the following several years.
This means the federal and North Carolina pictures for the same purchase can look very different in the year it is made, even though they eventually align over time. A large equipment purchase that produces a substantial federal deduction may still increase North Carolina taxable income for that year, which is worth modeling before committing to a major purchase based on the federal numbers alone.
Timing Your Q4 Equipment Decision
A year-end equipment purchase works best when it is planned rather than rushed. Before committing to a purchase with this year’s tax deduction in mind, it is worth working through the following:
- Confirm a current projection of taxable income, since that affects both whether Section 179 is available and how large a deduction actually helps.
- Check vendor lead times and installation schedules well ahead of December, since delivery delays are the most common reason a planned deduction slips to next year.
- Decide whether Section 179, bonus depreciation, or a combination of the two fits this year’s income picture best.
- Model the North Carolina addback and recovery schedule alongside the federal deduction before finalizing the decision.
- Confirm the equipment will be used more than half the time for business purposes, since mixed-use property has its own rules.
Our financial consulting team in Charlotte can help you run these numbers against your current year projections before you commit to a purchase.
Vehicles and Mixed-Use Equipment Carry Extra Rules
Passenger vehicles used for business are subject to separate depreciation limits that cap how much of their cost can be deducted, regardless of how the rest of Section 179 or bonus depreciation would otherwise apply. Heavier vehicles, including many SUVs and trucks above a certain weight threshold, are generally treated more favorably and can qualify for a much larger deduction.
Equipment used for both business and personal purposes has its own threshold to meet before it qualifies for these deductions at all, and the business-use percentage has to be supported by records if the deduction is ever questioned. These details are easy to overlook in the excitement of a large purchase, and they are worth confirming before the purchase is finalized rather than after.
Why Some Businesses Choose Not to Take Full Bonus Depreciation
Taking the largest deduction available is not always the right move. Some businesses elect out of bonus depreciation for some or all categories of equipment because a smaller deduction this year preserves depreciation to offset income in future years, particularly if this year’s income is lower than usual or next year is expected to look different.
This is a decision that benefits from looking at more than one year at a time. A CPA who understands both your current numbers and your plans for the business is better positioned to help weigh whether taking the full deduction now or spreading it out serves your situation best.
Frequently Asked Questions About Section 179 and Bonus Depreciation
What does “placed in service” actually mean?
Placed in service means the equipment is installed, operational, and ready to be used for its intended purpose, not simply purchased, delivered, or invoiced. The date it becomes usable in the business, not the purchase date, is what determines which tax year the deduction belongs to.
Can a business use both Section 179 and bonus depreciation in the same year?
Yes. The two are generally applied in order, with Section 179 taken first up to its limit and bonus depreciation available for qualifying costs beyond that, so many businesses use both on the same set of purchases.
Does North Carolina allow the full federal bonus depreciation deduction?
No. North Carolina generally requires most of the deduction to be added back in the year it is claimed, then recovered over the following years, so the federal and state pictures differ for the year of purchase.
Is used equipment eligible for bonus depreciation?
Generally, yes, as long as the equipment is new to the business and meets other qualifying requirements. This differs from older versions of the bonus depreciation rules, which limited the deduction to original-use property.
Timing Equipment Purchases to Make Section 179 and Bonus Depreciation Work
Section 179 and bonus depreciation offer some of the most direct tax savings available to a business, but only when the timing lines up. Waiting until the final weeks of the year to start the conversation often means the placed-in-service deadline, vendor lead times, or the North Carolina addback rules get overlooked until it is too late to plan around them.
