Hi, I was wondering if anyone could confirm whether I need to declare a property sale within 60 days of sale if a loss was made? There seems to be some contradictory information on the internet: some sites say that, regardless of whether you have tax to pay or made a loss, the deadline for informing HMRC is 60 or you will incur fines. Other sites say that you can declare on your next SA tax return or within 4 years of sale. This site has the info I'm referring to: https://www.gov.uk/capital-gains-tax/losses Thanks in advance.
