CT600 Box 275: Non-Trading Losses on Intangible Assets

Box 275 on the CT600 is for non-trading losses on intangible fixed assets. This is the opposite of Box 195 (gains) and applies when your company disposes of intangible assets at a loss.

What Goes in Box 275?

Box 275 captures losses arising from intangible assets held outside of a trade. This includes losses on:

  • Patents sold for less than cost
  • Trademarks that have diminished in value
  • Goodwill written off
  • Licences surrendered or expired
  • Intellectual property disposed of at a loss
Most small trading companies don't have non-trading intangible losses - Box 275 is typically zero.

Understanding Intangible Asset Losses

What Creates a Loss?

A loss arises when:

``` Disposal proceeds < Tax written down value ```

Example

ItemAmount
Original cost of patent£50,000
Tax amortisation claimed(£20,000)
Tax written down value£30,000
Sale proceeds£15,000
Loss£15,000

Types of Intangible Assets

Assets Covered

Asset TypeBox 275 Applies?
Patents (non-trade)Yes
TrademarksYes
CopyrightsYes
Goodwill (post-April 2002)Yes
LicencesYes
Know-howYes

Pre-April 2002 Assets

Intangible assets acquired before April 2002 follow different (capital gains) rules and don't create Box 275 entries.

When Box 275 Applies

Scenarios Creating Box 275 Entries

  1. Sale at a loss - Asset sold for less than book value
  2. Impairment - Asset written down due to reduced value
  3. Abandonment - Asset surrendered or allowed to lapse
  4. Expiry - Time-limited rights expiring worthless

Non-Trading Requirement

The asset must be held outside of a trade:

  • Investment in IP as a side activity
  • Patents not used in company's main business
  • Assets held by holding companies
Trade-related intangibles have different treatment.

How Losses Are Used

Relief Options

Non-trading intangible losses can be:

  1. Set against non-trading intangible gains (same period)
  2. Set against total profits (current period)
  3. Carried back to previous periods
  4. Carried forward to future periods

Example: Current Year Set-Off

ItemAmount
Trading profits£80,000
Non-trading intangible gains (Box 195)£20,000
Non-trading intangible loss (Box 275)(£25,000)
Net positionRemaining loss of £5,000

Calculating Box 275

Step-by-Step

  1. Identify intangible asset disposed of
  2. Confirm it was non-trading
  3. Calculate proceeds minus tax value
  4. If negative, enter loss in Box 275

Worked Example

A company holds a trademark as an investment:

ItemAmount
Acquired for£40,000
Amortised over 5 years (£8,000/year)(£24,000)
Tax written down value£16,000
Sold for£5,000
Loss for Box 275£11,000

Box 275 vs Box 195

BoxPurpose
195Non-trading intangible gains
275Non-trading intangible losses
Both relate to the same type of assets - just different outcomes:
  • Profit on sale → Box 195
  • Loss on sale → Box 275
BoxDescription
195Non-trading intangible gains
275Non-trading intangible losses (this box)
285Trading losses (for trade-related intangibles)
295Donations to grassroots sports

Most Small Companies: Box 275 = Zero

For typical small trading companies:

  • Intangible assets are usually trade-related
  • Few companies hold IP investments separately
  • Goodwill is typically only relevant on business sale
  • No separate intangible investment portfolios
If you don't hold non-trading intangible assets, Box 275 will be zero.

Common Questions

My company developed software we're writing off - is that Box 275?

Probably not. If the software was developed for your trade, any write-off would be a trading expense, not a Box 275 item.

We sold our trademark - where does the loss go?

It depends on use:

  • If the trademark was used in your trade → Trading loss
  • If it was an investment asset → Box 275

What about goodwill when closing a business?

Goodwill losses on cessation are complex:

  • Post-April 2002 goodwill → May be Box 275
  • Pre-April 2002 goodwill → Capital gains rules
  • Seek professional advice for business closures

My company acquired another company's IP and it's now worthless - Box 275?

If the IP was:

  • Acquired post-April 2002
  • Held as a non-trading investment
  • Now being disposed of at a loss
Then yes, Box 275 would apply.
