Back to Tax Basics: How capital allowances reduce your tax bill

Anna Stubbs • October 10, 2023

Generally speaking, the business expenses you incur are allowable against your profits. But when it comes to fixed asset purchases (things like machinery, equipment or vehicles), these purchases are treated slightly differently.

 

To reduce your tax bill when purchasing fixed assets, it’s important to know what capital allowances are available and how you can use them to enhance your tax planning.

 

In the next part of our Back to Tax Basics series, we outline which capital allowances are available and which assets they relate to.

What are capital allowances?

 

Fixed assets are classed as items of equipment that will be used in the business for more than a year – so, things like office furniture, machinery and company vehicles. For accounting purposes, the cost of these fixed assets is spread over the expected life by calculating a depreciation charge each year – in other words, the value the item will lose over this time.

 

  • For tax purposes, the depreciation is added back (disallowed) and ‘writing down allowances’ are claimed instead.
  • There is an Annual Investment Allowance (AIA), fixed at £1 million per annum for the forseeable future. Most asset purchases up to that total can be claimed in full in the year of purchase. The main exceptions are cars and items you owned for another reason before putting them into the business.
  • For some assets, 100% First Year Allowances (FYA) are available. These include:
  • New and unused vehicles with Nil CO2 emissions
  • New electric vehicle charging points
  • Plant and machinery for use in a Freeport
  • For everything else you might purchase as a fixed asset, the costs are allocated into various pools depending on the type of asset, and Writing Down Allowances (WDA) calculated on the pool value on a reducing balance basis. These include:
  • Special Rate Pool 6% rate – Cars (new or used) with CO2 emissions > 50 g/km, Integral fittings incorporated into commercial buildings (lifts, electrical and water reticulation, air conditioning, heating equipment), long-life (>25 years when new) items over £100K annual spend. Long-life excludes structures and buildings.
  • Main Rate Pool 18% rate – everything else. Note as specifics this includes cars with CO2 emissions >0 <50 g/km.
  • Structures and Buildings Allowance (SBA) – the SBA offers a 3% flat rate for 33.33 years on non-residential buildings, but not on land.

If you’re thinking of purchasing capital equipment, it’s worth knowing that, in many cases, the tax benefit can be claimed in a lump sum, even though the equipment may be in use for several years. This will have a positive short-term impact on both your tax charges and your cashflow.

In 1961, President John F Kennedy famously announced his goal of landing a man on the moon and returning him safely to Earth before the decade was out. As we know, in July 1969, Neil Armstrong and Buzz Aldrin became the first people to walk on the moon, and were brought back to Earth safely, achieving JFK’s goal.  At a time when most people hadn’t even been on an aeroplane, landing on the moon would’ve felt unachievable and overwhelming. However, such a massive goal united people with a purpose; the story goes that even a cleaner mopping the floor at the space station said his job was to help put a man on the moon. So, how did they make the goal achievable? They broke it down into milestones, with each one taking them closer and closer to achieving their ultimate goal. The first milestone was to achieve lift off. So, they set about resolving this challenge. The next milestone was to reach orbit, so they had a team working on this milestone. Then, they had to reach the moon’s atmosphere, land safely on the moon, take off from the moon, enter Earth’s atmosphere and land safely back down to Earth. You can see how breaking the goal down into milestones gave everyone a more achievable objective to focus on which was less overwhelming. Those milestones were then broken down into the actions which needed to be completed. Each action was essentially a small step towards reaching the ultimate goal.

Are you undercharging for your services? It can be hard to tell, particularly if you’re in a niche industry or you’re a contractor. Costs have been rising, so it may be time to rethink your own pricing.

For your business to make money, you need to generate revenue. You produce revenue through your usual business activity, by making sales, getting your invoices paid, or taking cash from paying customers. So, the better you are at selling your products/services and bringing money into the business, the higher your revenue levels will be. But what actually drives these revenue levels? And how do you get in control of these drivers?
