CT600 Box 210: Chargeable Gains Explained

Box 210 on the CT600 captures chargeable gains arising from the disposal of capital assets. This is where you report gains from selling property, shares, or other assets your company owns.

What Goes in Box 210?

Box 210 is for net chargeable gains after deducting allowable losses. This includes gains from disposing of:

  • Property and land
  • Shares and securities
  • Business assets
  • Equipment (in certain cases)
  • Intellectual property (pre-April 2002)
Most small companies don't sell capital assets, so Box 210 is typically zero.

Understanding Chargeable Gains

What Creates a Chargeable Gain?

A gain arises when your company sells an asset for more than it cost:

``` Chargeable Gain = Sale Proceeds - Original Cost - Allowable Costs ```

Allowable costs include:

  • Purchase price
  • Legal fees on acquisition
  • Improvement costs
  • Legal fees on disposal

Example Calculation

ItemAmount
Sale proceeds£150,000
Less: Purchase price(£100,000)
Less: Legal fees (buy)(£2,000)
Less: Improvements(£10,000)
Less: Legal fees (sell)(£3,000)
Chargeable Gain£35,000

Calculating the Net Figure

Box 210 requires the net position:

If Gains Exceed Losses

  • Total gains: £50,000
  • Less current year losses: (£10,000)
  • Less brought forward losses: (£5,000)
  • Box 210: £35,000

If Losses Exceed Gains

  • Enter zero in Box 210
  • Carry forward the excess loss
  • Use Box 220 for losses to carry forward

Indexation Allowance

For assets acquired before January 2018:

  • Indexation can reduce chargeable gain
  • Based on RPI increase from purchase to January 2018 (or earlier sale)
  • Cannot create or increase a loss
Example:
  • Cost in 2010: £100,000
  • Indexation factor to Jan 2018: 0.234
  • Indexed cost: £123,400
  • Sale proceeds: £150,000
  • Gain: £26,600 (not £50,000)

The Substantial Shareholding Exemption

Companies selling shares may qualify for SSE:

Conditions for SSE

  • Held at least 10% of ordinary shares
  • Held for at least 12 months
  • Selling company was a trading company
  • Company being sold was a trading company
If SSE applies, no gain (or loss) is recognised - nothing enters Box 210.

Most Small Companies: Box 210 = Zero

Typical small companies:

  • Operate from rented premises
  • Don't own investment properties
  • Don't sell shares in other companies
  • Keep the same assets year to year
If you haven't sold any capital assets, Box 210 will be zero.

Common Questions

My company sold a company car - does that go here?

Normally no. Cars are exempt from capital gains tax. Enter zero unless it was a vintage/classic car held as an investment.

We sold our office building - is that Box 210?

Yes. The gain on selling property (proceeds minus cost and fees) goes in Box 210.

What about shares my company holds?

If you sell shares for a gain:

  • Check if SSE applies (often exempt)
  • If not exempt, enter gain in Box 210
  • Losses can offset other gains

My company received compensation for damaged equipment - where does that go?

Usually not Box 210:

  • If it's revenue compensation → Trading income
  • If it's capital compensation → May be a chargeable gain
  • Often covered by rollover relief
