Delaying Capital Gain?

[MickyV]

I have built a pair of houses. One was sold a few months ago and the other is (hopefully!) due to complete at the end of March. If all goes according to plan, this would leave me with a Capital Gain of around £40k total. I do not expect to make any Capital Gains in 2018/19.

Is there any way (short of persuading the buyer to delay completion for a fortnight) that I can hold over the gain on the second house until April 6 so I can take advantage of my 2018/19 allowance?

Apart from anything else, experience on the first sale shows it would be prudent to hold back £5-10k to use for snagging issues which I will be liable for over the first few months. Can I reasonably withhold that?

You are missing a few difficulties First building houses for sale for profit is possibly not a capital gain but trading profits with a different method of calculation.

However if it is a CG then the year of the gain is determined by the date of exchange of an unconditional contract

Not completion

Thank you.

Much appreciated
