Rollover relief allows a trader to defer the payment of capital gains tax where the disposal proceeds of a business asset are reinvested in a new business asset. The deferral is achieved by deducting the chargeable gain from the cost of the new asset. It can be where proceeds are fully or partially reinvested.
Example 1 – proceeds fully reinvested
David sold a factory on 1January 2010 for £300,000 and this resulted in a chargeable gain of £80,000.
If David is replacing the old factory with a new factory costing £350,000, he can make a claim to defer the gain he has made.
The amount deferred (in this case £80,000) is rolled over and reduces the base cost of the new asset purchased. So the base cost of the new factory will be £270,000 (being cost of £350,000 less rolled over gain of £80,000).
Example 2 – proceeds not fully reinvested
Eve sells a business asset for £500,000 realising a capital gain of £100,000.
Eve uses the money to buy an office block used for the purpose of her trade which costs £480,000.
As Eve has not spent the entire sale proceeds, the cash retained of £20,000 (£500,000 less £480,000) is immediately chargeable to capital gains tax.
The remainder of the gain (£80,000) is rolled over into the base cost of the replacement asset. The base cost of the new asset is £400,000 (being amount paid £480,000 less gain rolled over £80,000).
