Capital tax due after marriage

My wife and I got married in 2023 after being together for 3 years. We each owned and lived in our own properties as both our families and jobs were 85 miles away from each other. I have recently sold my property and moved permanently into her house. Is there capital gains tax to pay on the sale of my property? I had owned my house since 2006 and she has owned hers since 2017.

Hi,
You can see guidance here:
Tax when you sell property
Tax when you sell your home
Thank you.
 

Not HMRC, as two single people you were both entitled to main residences, and any gains to the point of marriage are covered by PPR exemption. After marriage you are only entitled to one PPR. Your gain from 2006 to 2023 (on marriage) is covered, plus final nine months, you may be liable for a few months from Marriage (+9) to sale?...calculation is net sale proceeds, less total costs gives gain. Multiply gain by number of months main residence (month in 2006 to month of marriage in 2023) (plus 9) divided by the total number of months owned (to sale)...thats the exempt amount, difference liable (after annual exemption)
