Income tax allowance and CGT

[flatree]

My wife and I sold a jointly-owned second property in the 2016-17 tax year. I had originally bought the property in 1996 and gifted her half in 2014-15. My wife had negligable income in 2016-17 (less than £1000 from savings interest). When working out her CGT, does she include the unused income tax allowance as well as the CGT allowance? Her share of the sale is as follows: sale price £105,000, purchase price £14,000, purchase plus sale fees £1500, improvements £5000, her other income for 16-17 was essentially £0, CGT allowance £11,100. How much CGT will she pay?

Many thanks

No.

Using your figures at face value and assuming these relate to wife only then:
Gain = 105,000 - [14,000 + 1,500 + 5,000] - 11,100 = 73,400.

CGT = 18% x 73,400 = 13,212.

.....except not all of the £73,400 gain is liable at 18%.
the element that takes her above basic rate threshold (32k for 16/17) is liable to the top rate of 28%.

so based on no other income £41,400 @ 28% = £11,592
£32,000 @18% = £5,760
