Carrying forward losses over multiple years: a bug in the self-assessment form?

[Marc007]

Hi James, I have the same issue and I wrote to HMRC and they said that if I had loses from previous years to carry forward then I would have to keep track of them myself. I share your concern about the 2017/18 return showing no loss to carry forward because it auto calculates and then actually entering a value for the 2018/19 return. I don't think that they have given much thought to this TBH and everything is based around the new system of adding the profit on to any of your other earned income and then giving you the 20% tax credit for the finance costs at the end. It also means that any losses from previous years will be quickly used up. There are some examples on HMRC's website and it clearly says that the tax credit should not result in a tax refund. It states that the tax credit will be the lowest value of either the profit, the finance costs or the total income. Hence, if you have zero profit then you will have zero tax credit. If I understand the example correctly it means that we will be able to carry forward the unused finance cost until we eventually go into profit.

PS: there is an obvious (although untidy) away around this problem, I realise, which is simply to put £17,337 in the "Loss brought forward used against this year's profit" box, and then I can simply remember to put the £22,680 further carried over loss on my 2018/19 return. However, my worry is that this would look odd to HMRC if they cross-reference the two years' returns.

In 2017/18, I made £17,337 profit on my property rentals. However, I had a £40,017 loss from previous tax years to carry over, which should both wipe out my profit for 2017/18 and leave me with a £22,680 remaining loss to carry forward to 2018/19.

I put this into my self-assessment form, and the website came up with the attached screenshot, which all looks exactly how it should be. Happy days, I thought!

However, when I clicked "next" I got the following error message: 'Loss brought forward used against this year's profits' must not exceed 'Adjusted profit for the year'. Please amend.

Aaargh! I then clicked on the help icon next to the "Loss brought forward used against this year's profit" box and it came up with the following (I've put the key sentence in blue text):

Loss brought forward used against this year’s profit
Enter any loss brought forward from earlier years up to the amount in ‘Adjusted profit for the year’ .Include any amount brought forward that you're now setting against 2017 to 2018 Income from Property profits. This figure must not exceed the 'Adjusted profit for the year' figure. If your loss is higher than your profit, provide the remaining losses available to carry forward in the 'Loss to carry forward to following year, including unused losses brought forward’.

That sounds all well and good, but as you can see from the attached screen shot the "Loss to carry forward to following year, including unused losses brought forward" box is not one which permits numbers to be inputted by the user, but is instead (quite sensibly) one which the HMRC website calculates for you based on your previous answers in that section. Aaargh, aargh, aargh!

Am I missing something obvious, or is this a bug in the HMRC website?
