If you’re running a Limited Company, you’re likely used to the idea that buying gear for your business comes with a nice little silver lining: tax relief. Whether it’s a new fleet of vans, high-tech machinery, or even just the desks and chairs in your office, the taxman usually lets you deduct a portion of those costs from your profits before they calculate your Corporation Tax bill.
However, as of April 2026, the rules of the game have shifted. Specifically, we’ve seen a significant cut to what’s known as the Writing Down Allowance (WDA).
At Makes Sense Accountants, we’re all about making the complex stuff simple. You don't need a degree in tax law to understand how this affects your back pocket, but you do need a plan. Let’s break down exactly what has changed, why it matters for your cash flow, and how you should be thinking about your next big purchase.
What on earth is a Writing Down Allowance (WDA)?
Before we dive into the cuts, let’s clear up the jargon. When your company buys an "asset" (something big that lasts a long time, like a tractor, a computer system, or a CNC machine), you usually can’t just claim the whole cost as an expense in one go like you would with a pack of pens or a utility bill.
Instead, HMRC expects you to spread that tax relief over several years. This reflects the fact that the asset is wearing out (depreciating) over time. The Writing Down Allowance is the percentage of the value you’re allowed to knock off your taxable profits each year.
Up until April 2026, the "main rate" for most equipment was 18%. From 1 April 2026, that rate has dropped to 14%.
It might not sound like a huge leap, only 4%, but because of how the math works, it can have a massive impact on how quickly you get your tax money back.
The "Reducing Balance" Trap: Why 14% is slower than you think
The WDA works on a "reducing balance" basis. This means you don't just get 14% of the original price every year. You get 14% of whatever is left in the pot.
Let’s look at a quick example. Imagine your company buys a piece of machinery for £100,000. (We’ll assume for a second you aren’t using other reliefs like the Annual Investment Allowance, more on that later).
Under the old 18% rate:
- Year 1: You claim £18,000. Your taxable profit drops by £18k.
- Year 2: You claim 18% of the remaining £82,000, which is £14,760.
- Year 3: You claim 18% of the remaining £67,240, which is £12,103.
Under the new 14% rate:
- Year 1: You claim £14,000.
- Year 2: You claim 14% of the remaining £86,000, which is £12,040.
- Year 3: You claim 14% of the remaining £73,960, which is £10,354.
By the end of Year 3, you’ve claimed about £8,000 less in tax relief under the new rules. That’s £8,000 more "profit" that HMRC is going to look at and say, "I’ll have my 25% of that, please."
In short: you still get the tax relief eventually, but it takes much, much longer. And in business, we all know that a pound in your pocket today is worth much more than a pound in your pocket five years from now.
Why this changes the way you buy assets
Now that we’re living in the post-April 2026 world, "just buying it and letting the accountant handle it" isn't the best strategy. You need to be proactive. Here is how the 14% cut should change your thinking:
1. The hunt for 100% relief is more important than ever
Because the 14% pool is so slow, you want to avoid it whenever possible. Fortunately, there are still ways to get 100% tax relief in the very first year.
- Annual Investment Allowance (AIA): This is still your best friend. It allows most businesses to claim 100% of the cost of plant and machinery up to £1 million per year. If your total annual spend is under £1m, you might not feel the 14% cut at all: if you use your AIA correctly.
- Full Expensing: For Limited Companies buying new (not second-hand) equipment, full expensing is a game-changer. It gives you 100% relief upfront.
The danger is for businesses that go over the £1m AIA limit or buy assets that don't qualify for these 100% schemes. If you’re planning a massive expansion, you need to be very careful about how you stage your purchases so you don't get stuck in the slow 14% lane.
2. The new 40% First Year Allowance (FYA)
Introduced in early 2026, there is now a 40% first-year allowance for certain assets that don't qualify for full expensing. This is a bit of a "middle ground." It’s better than the basic 14%, but not as good as 100%. If you can’t get 100%, we should be looking to see if your purchase qualifies for this 40% kickstart to help your cash flow in Year 1.
3. Buying vs. Leasing: The math has shifted
This is where it gets interesting. When you buy an asset, you own it and claim WDAs (at the new, slower 14% rate). When you lease an asset (like an operating lease), you don't own it, but you can usually deduct the entire monthly lease payment as a business expense.
Before April 2026, the 18% WDA was often "fast enough" to make buying more tax-efficient than leasing. Now that the WDA has dropped to 14%, leasing might actually be the winner for certain types of equipment or vehicles. It gives you a more immediate tax deduction and keeps more cash in your business.
If you're unsure which route is better for your LTD company, it's definitely time to run the numbers.
Timing and Asset Classification: Don't leave it to chance
The way your invoices are written and how your assets are classified now matters more than ever.
Separation is key
If you are doing a big office fit-out, for example, some parts might be considered "integral features" (which have an even lower rate of relief), and some might be "main rate" plant (now 14%).
We often see businesses get lazy with their invoicing, putting everything under one "Refurbishment" line. That is a mistake. By properly separating your assets on your invoices, we can ensure that every possible penny is put into the highest-rate tax relief category available.
Strategic Timing
If your company’s year-end is approaching and you’ve already used up your £1m AIA, it might make sense to wait until the first day of your next financial year to make a big purchase. This resets your AIA limit and could mean the difference between getting 100% relief now or 14% relief over the next decade.
