Can i know that what is the limitation of regarding mortgage relief? Is that base on the amount of mortgage interest amount or the tax due? However base on my testing on the system, when i input the same income in UK section but not oversea section, I can see the relief finally. I saw the post telling the same system fault in the community, when tax payers input the rental income and the mortgage interest expense in UK section but not oversea, the system shows the relief as expect. Could you please explain?

I have input my tax calculation like the following : Foreign income after all allowance: £8358 Foreign savings £ 12140 therefore total income received £8358+£12140= £20498 minus personal allowance £12570 total income on which tax is due £20498-£12570=£7928 income tax charged afer allowance and relief in basic rate (£7928-£6000)x20%=£1928 x 20%= £385.6 minus Marriage allowane transfer £ 252 I had £8289 finance cost filled in 24.1 of SA106 however i saw £0x20% in the line (which i expect it should be £8289 x 20%= £1657.8 while i have the relief) minus Reflief for finance costs £8289 reduced to maximum allowable £0x20% and this made the final Income Tax due after tax reductions £385.6- £252= £133.6 only (which i expect it should be £385.6- £252- £1657.8) Can i know the reason i dont have the relief of finance cost of residential property?
