Guidance from HMRC

The following guidance from HMRC will help you to understand what is restricable and what is not-restrictable:
The following extract from Tax relief for residential landlords explains how it's worked out:
The reduction is the basic rate value (currently 20%) of the lower of:
  • Finance costs
    : costs not deducted from rental income in the tax year (this will be a proportion of finance costs for the transitional years) plus any finance costs brought forward.
  • Property business profits
    : profits of the property business in the tax year (after using any brought forward losses).
  • Adjusted total income
    : income (after losses and reliefs, and excluding savings and dividends income) that exceeds your personal allowance.
The tax reduction can’t be used to create a tax refund.
If the basic rate tax reduction is calculated using
property business profits
or
adjusted total income
, then the difference between that figure and
finance costs
is carried forward to calculate the basic rate tax reduction in the following years.
If you cannot use the finance charge in the current year, for example if the profit is covered by the personal allowance or by losses brought forward, then the unused finance charges can be carried forward to the following year.
To find the workings for loss utilisation and enter any brought forward loss for new clients manually: go to the

Self Assessment: SA903 Trust and Estate UK Property

You'll only receive the 20% tax reducer directly within the tax computation if the trust pays tax at the higher trust rates.  The trust pays at the lower trust rates, the reducer is passed to the beneficiary through Form R185 for them to claim themselves.
HMRC's Trust and Estate UK Property Notes to Form SA903 explain where to enter residential property finance costs:
Accumulation or discretionary trusts enter residential finance costs in box 3.46. This amount will be used to calculate a reduction in income tax.
For interest in possession trusts and estates of deceased persons, finance costs must not be entered in box 3.46. Instead, the finance costs are used by the beneficiaries as a basis for calculating their basic rate tax reductions. You’ll need to tell the beneficiaries the figures for the profits of each property business and the finance costs that relate to each business.
