I have two rental properties, which earned me £6,693 in the tax year 2020/21. However, following the introduction of the mortgage interest relief restriction, there is a profit of £13,506 for property on my return. What I can't find clarification on is: does a couple with children on working tax credits and child tax credit need to put this figure down as income for tax credits renewal purposes? I don't feel it is an accurate representation of the actual income we received.

If you look at the HMRC’s Tax Credits manual at TCM0120160 and TCTM04006, you can see it states that after April 2017, ‘For the purposes of tax credits, a person will still be able to deduct 100% of their finance costs when calculating their allowable expenses for property income’, unlike calculations for income tax.
