Long-Life Assets for Capital Allowances

When businesses invest in plant and machinery, one of the key considerations for tax relief is how that expenditure is classified. A particularly important category is long-life assets, which are subject to specific capital allowances treatment.

What is a Long-Life Asset?

A long-life asset is an item of plant or machinery that is expected to have a useful economic life of at least 25 years.

• If the asset is new, the expectation is based on its anticipated lifespan from first use.

• If the asset is second-hand, the test looks at what its lifespan would reasonably have been when it was new.

Importantly, this 25-year test applies to the asset as a whole, rather than breaking it down into individual components.

What Does “Useful Economic Life” Mean?

The useful economic life of an asset is not limited to how long your business intends to use it. Instead, it covers the entire period:

• From when the asset is first brought into use by any business

• Until it is no longer likely to be used by anyone as a business asset

This means the lifespan used for capital allowances purposes can often be longer than the accounting life shown in your financial statements.

How Are Long-Life Assets Treated?

Expenditure on long-life assets is usually allocated to the special rate pool, which attracts a lower rate of tax relief:

• Writing-down allowances are typically given at 6% per year on a reducing balance basis

However, there are more favourable options available in certain situations:

• The Annual Investment Allowance (AIA) may allow you to claim 100% relief upfront, depending on your circumstances

• Some types of expenditure may qualify for enhanced first-year allowances, offering accelerated tax relief in the year of purchase

The £100,000 Threshold

Not all long-life asset expenditure is treated as such automatically.

There is an annual threshold of £100,000:

• If total spending on long-life assets in a period does not exceed this limit, the expenditure can often be treated under normal plant and machinery rules

• If the limit is exceeded, the long-life asset rules apply

This threshold is adjusted for shorter or longer accounting periods and may be shared or reduced where businesses are part of a group.

There are also situations where this threshold does not apply, such as certain leasing activities.

Fixtures and Integral Features

Long-life assets can include fixtures and integral features within buildings. However, there are notable exceptions.

Assets are generally excluded from long-life treatment if they are:

• Installed in buildings used mainly as homes, hotels, offices, shops, or showrooms

• Used for purposes related to those types of buildings

In addition, certain assets are always excluded, such as:

• Cars and motorcycles

• Specific industry assets that have been agreed as exceptions

Other Key Points

• The expected lifespan is always assessed based on the asset when new, even if purchased second-hand

• Once an asset is classified as a long-life asset, that treatment is fixed, even if the asset is later sold

• Some assets, such as solar panels, are specifically treated as long-life assets

Final Thoughts

Long-life asset rules can significantly affect the timing and amount of tax relief your business receives. Misclassifying expenditure can mean missing out on valuable upfront deductions or applying the wrong rate of relief.

If you’re planning capital expenditure or want to ensure you’re maximising your claims, it’s worth getting the right advice early.
