claim 20% mortgage loan interest relief for finance cost of property

Dear Sir, I am inputting the figure of tax yar 2022-2023 online. I have a letting property with mortgage to earn my rental income. As per my understanding the finance cost - mortgage interest expense can claim a tax relief. It can be claim 20% of the financal cost. e.g. £7,668 was the interest i paid in tax year. 20% of it = £1533.6 should be deduced my payable tax. However when i entered the amount in "Residential property finance costs "field. and submitted my form. In the section " how we have worked out your income tax", I can only see "minus Relief for finance costs £7,668.00 reduced to maximum allowable" but the amount right to it is £0 x 20% thus the total was also £0. and no reduction on "Income tax due after tax reductions." Can you tell me what wrong with my input /?

Hi
Thank you for your question.
Firstly, your understanding is correct, you may claim interest paid on a mortgage at the restricted rate of basic rate, so in your case, 20% of the £7,668.00, which you have stated totals £1533.60.
The information inputted into your Tax Return will determine how much relief is given against any property income profits for that given year.
It appears in your case that a large enough profit was not made during the 2022/2023 tax year to use said relief against, for example a loss has been made.
I would advise that you would have to carry forward the unused finance costs to a future year.
The following link gives further information when no tax reduction will be given or it is reduced.

Can I claim the amount or a proportion of the interest on my help to buy loan (as I have permission to let out my help to buy property).

Hi, 
You can claim relief, see - Work out your rental income when you let property Allowable expenses
Thank you.

I am in the same situation as the original poster. I have some mortgage interest to claim as residential property finance costs, but there is insufficient profit for the costs to be used for tax relief (as shown in the fill tax calculation). How do I carry forward the unused financial costs to a future year; what box or section do I enter the costs in to be carried forward? Thanks

Hi,
There is no box for you to enter the unused finacial costs. You will need to keep a record of these and enter them in box 45 of your return for the following year to use these against any future profit.
Thank you.
