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.

The latest edition of the Federation of Small Businesses’ (FSB) Small Business Index had some unexpected results when it comes to growth expectations of UK small businesses. 27% of businesses said they expected their business to shrink, close or sell up over the next year. This outweighed the 25% who predicted their business would expand over the same period. It’s the first time in the history of the SBI that expectations of contraction have outnumbered those of growth. And it underlines a growing trend.

One of the best things about online shopping is instant, hassle-free payment. Enter your details, click, and you’re done. If your customers can make an instant online payment, they’re likely to pay you more quickly – and they’ll appreciate the simplicity too. The details Online payment methods include credit and debit cards, ACH (Automated Clearing House) services like Paypal, and repeat payments through direct debit. Payments are managed by merchant service providers – specialist companies that process transactions on your behalf. Some focus on credit and debit cards, while others stick to ACH or direct debit. Choose a provider that can integrate with your accounting software, and you can add a super-simple payment button to future invoices. The costs While your merchant service provider shouldn’t charge any set-up fees, they will charge transaction fees. These range from 2-4% of the invoice for debit or credit cards, and under $2 a transaction for direct debit. These fees are an added expense, so they need to be included in your profit calculation – smart accounting software will do this automatically. Because credit and debit fees can add up, many businesses don’t offer online payment for invoices over a certain amount. The benefits Businesses using online payments get paid faster. Of course, not every client will pay instantly just because they have the option, but it should speed up your average payment time.  A bonus benefit? Customers appreciate the ability to pay online, so offering it as an option can be a big point in your favour. Ready to reap the benefits of online payments?
