Year-End Hardware Refresh: What to Replace Before December

Every November I get a version of the same call. Somebody’s accountant has mentioned that buying equipment before year-end might help, and now there is a budget, a deadline, and no list. So the question lands on me: what should we replace?

That is the right question in the wrong order. The tax treatment is a reason to time a purchase you were going to make anyway. It is not a reason to make one. So: the list first, the calendar second.

One thing up front, and I will say it again later: this is not tax advice. I run field operations for an IT company. Everything below about how equipment purchases are treated is a plain-language description of a concept so you know what to ask. Your CPA tells you whether and how it applies to your business.

Four Tests for “Genuinely Due”

Run every machine through these in order. The first it fails tells you what you are dealing with.

1. Can it run a currently supported operating system? The only binary test. Microsoft ended support for Windows 10 on October 14, 2025, and machines that cannot meet the hardware requirements for Windows 11 stop receiving security updates once any extended-update arrangement lapses. Extended Security Updates are available to businesses for a limited window at a per-device cost that rises each year — a bridge, not a plan. A machine that fails this test needs replacing, no matter how nice it is to type on.

2. Is it under warranty, and what happens the day it is not? Out of coverage, a dead drive or power supply becomes your problem to source, pay for, and wait on — with the machine sitting idle meanwhile. Look up coverage by serial number on the manufacturer’s support site and write the expiry date next to each device on your list.

3. Is anyone waiting on it? The test people underweight, and the one with the clearest math. If a machine costs an employee twenty minutes a day — slow logins, an application that takes a minute to open a record, a browser that stalls — that is roughly two working weeks a year of paid time on one device. Multiply by the number of people on similar hardware. That number settles the argument faster than anything technical.

4. What breaks if it dies tomorrow? The five-year-old workstation nobody uses much can wait. The five-year-old workstation running the one application that produces invoices cannot. Rank by consequence, not by age.

What People Just Dislike

Half the “this computer is terrible” complaints I chase are not the computer. Before you buy, rule out the cheap fixes:

• A nearly full disk. A drive with almost nothing free behaves like failing hardware. Clearing it is free.
• Security software stacked on security software. Two endpoint products fighting each other will bring a healthy machine to its knees.
• The network, not the PC. If the file server sits across a saturated link or the access point is ten years old, every machine on that floor feels slow. Replacing one fixes nothing.
• A mechanical hard drive in an otherwise fine machine. A solid-state drive and more memory can buy another year or two for a fraction of a new machine.
• The peripherals. A cramped monitor, a dying keyboard, or a bad dock generates “my computer is bad” complaints constantly and costs almost nothing to fix.

None of this applies if the machine failed test one. If it cannot run a supported OS, do not spend money extending its life.

Sort Into Four Piles

Put every device in exactly one column. Do this in a spreadsheet, with serial numbers, so it is still useful next year:

• Replace now — fails the OS test, out of warranty on a critical role, or actively costing staff time every day.
• Replace next year — on the clock but not urgent. This becomes your opening capital line for the following budget.
• Repair or upgrade — memory, a drive, a monitor, a dock. Cheap, fast, buys real time.
• Leave alone — works, supported, nobody is waiting on it. Resist the urge to tidy.

If you want the wider frame for how this list turns into a number, we walk through it in IT budgeting for small business.

Don’t Forget the Things Without Keyboards

Workstations get attention because people sit at them. The equipment that takes an office down is usually what nobody looks at.

• Firewalls run on a support and licensing lifecycle. Once a model stops receiving firmware updates, it is a security appliance with no security fixes. Check the vendor’s end-of-support date.
• Switches and access points age out of standards more than they fail. If everyone is on newer laptops and the wireless is still decade-old gear, the wireless is the bottleneck.
• UPS batteries are consumables. A unit with dead batteries reports itself as fine right up until the power blinks and the server drops hard.
• Backup appliances and target storage quietly run out of capacity as data grows — worth checking against your restore testing. We cover what usually goes wrong in the five things missing from most disaster recovery plans.

Why the Calendar Matters, Operationally

Before the tax part, there are two practical reasons December is a real deadline.

Lead times. Business-class hardware is built to order, and Q4 is when everyone else is ordering too. Between order, delivery, imaging, and deployment, a mid-December order for a meaningful number of machines is optimistic. Early November is comfortable.

Deployment windows. The quiet week between the holidays looks like the perfect time to swap machines, and sometimes it is — if the swap is planned, staffed, and reversible. But a skeleton crew is the wrong audience for an unplanned change. Schedule the cutover deliberately, keep someone who can undo it reachable, and do not stack it on other changes.

The Tax Angle, in Plain Language

Here is the concept, and only the concept. Normally, when a business buys equipment, the cost is deducted gradually over several years through depreciation. Section 179 of the federal tax code allows many businesses to elect to deduct the cost of qualifying equipment in the year it is placed in service instead. Qualifying property generally includes business computers, servers, network equipment, and certain off-the-shelf software.

The phrase that trips people up is placed in service. It generally means the equipment is set up and ready for its intended use in the business — not merely ordered, not merely invoiced, and not sitting in a box in the storage room on December 31. That is the operational reason lead times and deployment scheduling actually matter to the tax question.

Now the caveats, and they are not boilerplate:

• There are annual dollar limits and phase-out thresholds, adjusted from year to year. We deliberately do not publish figures, because any number we print goes stale.
• There are rules about business-use percentage and limits tied to your taxable income. The election is not automatically available in full to every business every year.
• Some states, including California, do not fully conform to the federal treatment. A purchase can be handled one way on a federal return and differently on a state return.
• Section 179 is a deduction, not a credit. It reduces the income you are taxed on; it does not reduce your tax bill dollar for dollar, and it does not make equipment free.

None of the above is tax advice, and we are not qualified to give it. Take the list you built to your CPA, ask how these rules apply to your business this year, and let their answer inform the timing — not the decision about what you need.

The Test That Should Actually Drive the Purchase

The right sequence: build the replacement list on the four tests, price it, then ask your accountant whether year-end timing helps. If the list is short and the answer is “buy it in January,” buy it in January.

What should never happen is the reverse — buying equipment nobody needed to capture a deduction. A deduction on an unnecessary purchase still leaves you out of pocket for most of what you spent.

To price the other side of the decision, look at what deferring costs. We work through how to calculate an hour of downtime from your own numbers in the real cost of IT downtime. Next to a purchase price, that figure usually makes the ranking obvious.
