Section 24 For Portfolio Landlords: A Practical Guide

6 min read·February 2026

Section 24 affects how finance costs are treated and can materially change net outcomes. Good records and clear property-level views are critical.

01

Why portfolio landlords feel it harder

The larger the portfolio, the more difficult it is to maintain clean attribution of finance costs, repairs, and recurring expenses without software support.

02

Control what you can control

You cannot change legislation, but you can reduce operational uncertainty. Strong transaction coding and regular review cycles protect decision quality.

03

Build for accountant handoff

Organise data so your accountant can verify quickly. This improves confidence and shortens turnaround when filing deadlines approach.
