You will be aware of the limits placed on claiming a deduction for interest on money borrowed to buy residential rental property.
If you have owned property before 27 March 2021, your claim for interest reduces over time through to 31 March 2025. For the current year, interest incurred is claimable in full up to 30 September 2021 and for the remainder of the year your tax claim is reduced to 75 percent of the interest you pay.
Just a small point: It is the interest you have “incurred” as opposed to the interest you have paid. Therefore, if you paid interest on 15 October 2021 for the period 16 September 2021 to 15 October 2021, you will see some of the interest relates to the time before 1 October and can be claimed in full.
