Section 179 and Bonus Depreciation in 2026: A Year-End Equipment Buying Guide

For 2026, a small business can deduct up to $2,560,000 of qualifying equipment and software in the year it buys it, under Section 179. Bonus depreciation can cover the rest at 100%. The catch is timing: the asset must be placed in service by December 31, 2026, not merely ordered.

If you plan to buy a truck, laptops, a printer or a piece of production equipment, the next ten weeks matter. At Emazoo, we write about how businesses run day to day, and year-end purchases are where cash flow and taxes meet. This guide covers the 2026 limits, how Section 179 and bonus depreciation differ, a worked example, and the mistakes that cost owners the deduction.

What Are the 2026 Section 179 Limits?

The 2026 Section 179 limit is $2,560,000, and it starts to shrink once you place more than $4,090,000 of qualifying property in service. The IRS published these numbers in Revenue Procedure 2025-32. The deduction disappears entirely at $6,650,000 of purchases.

Most small businesses never come near those limits. What matters more is the rule that a Section 179 deduction cannot exceed your business income for the year. If you earn $60,000 in business profit and buy $100,000 of equipment, you deduct $60,000 now and carry the rest forward.

The IRS lists the rules on its Publication 946 page, which explains how to depreciate property. You claim the deduction on Form 4562, filed with your business return.

Section 179 or Bonus Depreciation: Which Should You Use?

Section 179 lets you choose which assets to expense, while bonus depreciation applies automatically to eligible property unless you opt out. Bonus depreciation at 100% was made permanent for property acquired after January 19, 2025 by the 2025 tax law. It has no business income limit, so it can create a loss that carries forward.

The table below compares the two in plain terms.

Many owners pick Section 179 for flexibility, then let bonus depreciation absorb what remains. Your accountant can model both. Ask for the result with and without the deduction, so you can see the real change in your tax bill.

What Equipment Qualifies?

Qualifying purchases include machinery, computers, office furniture, off-the-shelf software and vehicles used in the business. Buildings do not qualify, though some improvements to non-residential buildings, such as roofs, HVAC systems and fire protection, can. Business use must be more than 50% of the asset's use.

Software is easy to miss. Off-the-shelf software you buy outright can qualify, while a monthly subscription is a regular expense you already deduct. If your team is replacing old Windows machines, our guide on Windows 10 ESU year-two costs shows what extending support costs against buying new hardware.

Vehicles need extra care. A heavy SUV with a gross vehicle weight rating between 6,001 and 14,000 pounds is capped at $32,000 of Section 179 expensing. Cargo vans and trucks with a bed of at least six feet may be treated differently. Check the vehicle's weight rating and business-use log before you buy.

Keep one more rule in mind. A Section 179 deduction can be recaptured as income if business use of the asset later drops to 50% or below. A truck you move to mostly personal use two years from now can bring part of the deduction back into your income. Track use over the life of the asset, not only in the first year.

A Worked Example for a Small Shop

Say a small print shop earns $140,000 in profit and buys a $48,000 press and $12,000 of computers in November. The shop installs both before December 31. It elects Section 179 for the full $60,000.

Taxable business income drops from $140,000 to $80,000. If the owner's combined federal rate on that slice is 24%, the federal tax falls by about $14,400. The shop still spent $60,000 in cash. The deduction saves tax, but it does not repay the purchase.

That last point trips up many owners. A $60,000 purchase that saves $14,400 in tax still costs $45,600 net. If you would not buy the press without the deduction, the deduction alone is a poor reason to buy it.

When Does Equipment Count as Placed in Service?

Equipment counts as placed in service when it is installed and ready for its intended use. Ordering it, paying for it or having it delivered to a warehouse is not enough. A press stuck in a crate on December 31 does not count for 2026.

That is why year-end buying has a practical deadline well before the last day. Supply delays, installation schedules and holiday closures all interfere. Aim to have major purchases delivered and running by mid-December, and keep the invoice, delivery receipt and a note of the in-service date.

A short list of records protects the deduction if the IRS asks questions.

Buying on Credit or a Loan

You can generally take the deduction in the year you place the asset in service, even if you pay for it over time. A financed purchase still counts, so a loan or an equipment lease that is treated as a purchase can qualify. That makes year-end buying possible without draining cash.

Be careful with the cash side. Monthly payments, interest and the effect on your credit line all matter. Test a purchase the way you would test software. Our guide to picking a first tool and running a 30-day pilot shows how to size a buy before you commit, and the same logic applies to larger equipment. Build a cash-flow forecast before you sign. Check that you can cover payroll and taxes in the first quarter of 2027.

Should You Buy, Lease or Wait?

Buying is not always the best choice. If equipment will be obsolete in two years, such as laptops or phones, leasing or paying monthly may keep your cash free. If the asset will last ten years, such as a heavy press or a delivery truck, buying usually wins.

Waiting is also a valid answer. A deduction in 2026 only moves tax between years. If you expect higher profit next year, deferring the purchase can give you a bigger deduction when your tax rate is higher. Owners with a rising business often get more from next year's deduction than this year's.

Consider the three questions below before any year-end purchase.

Common Mistakes That Cost the Deduction

A handful of errors cause most missed deductions. Owners buy assets that arrive after year-end. They claim a vehicle with low business use. They forget that the Section 179 deduction cannot exceed business income. And they ignore state rules, which can differ from federal limits.

State treatment is a real gap. Some states do not follow the federal Section 179 limit or the bonus depreciation rules, so the deduction may be smaller on your state return. Ask your accountant to check both returns before you buy.

Contractors and employees also raise questions. If you bought equipment for a worker you classify as a contractor, see our explainer on the 1099 threshold for contractor payments in 2026. The way you pay people affects your records and your year-end reports.

Questions to Ask Your Accountant

A fifteen-minute call can settle most doubts. Bring your year-to-date profit, a list of planned purchases and the in-service dates. Ask how each purchase changes your estimated tax payment for the fourth quarter.

Also ask about the qualified business income deduction, which can interact with a large expensing deduction. A bigger deduction lowers your profit, and that can lower the pass-through deduction too. Your accountant can show the combined effect in one table.
