Reintroducing Interest Deductibility – the Rules are finally here!
In a significant move aimed at providing relief (and fairness) to property investors, the Government has finally released the draft legislation to reinstate the ability to claim interest deductions for residential investment properties. The proposed changes are scheduled to come into effect from April 1, 2024, one year from the previously proposed implementation date – but better late than never.
The interest limitation rules, initially introduced in 2021, aimed to curtail interest deductions for residential investment properties. Under these rules, interest deductions were gradually phased out based on the acquisition date of the property. However, recognizing the need for a balanced approach, the government is now proposing to reintroduce interest deductibility in a phased manner.
The Annual Rates for 2023-24, Multinational Tax, and Remedial Matters Bill proposes a phased reintroduction of interest deductibility for residential investment properties. From 1 April 2024 to 31 March 2025, taxpayers will be allowed to claim 80% of interest deductions. Subsequently, from 1 April 2025, onwards, 100% deduction of interest will be permitted. Importantly, this phased approach applies to all taxpayers. This will provide some immediate relief (from 1 April this year anyway) to those taxpayers who acquired their properties after 27 March 2021.
Key Features
- Phased Reintroduction
Interest deductibility will be phased back in, with taxpayers allowed 80% deductions from April 2024 to March 2025, followed by 100% deductions thereafter. - Universality
The reintroduction of interest deductibility applies universally to all taxpayers, irrespective of the acquisition date of their properties. - Scope Retention
The rules governing the types of properties and taxpayers subject to interest limitation will remain unchanged during the phased reintroduction period. Any taxpayers, or types of land, that are currently exempt from the interest limitation rules will continue to be exempt. - Sunset Clause
The interest limitation rules are proposed to be repealed from April 1, 2025, once full deductibility is restored. - Deductions on Sale
Rules allowing taxpayers to deduct previously disallowed interest upon the sale of the property will be retained.
Details
- Application
The reintroduction of interest deductibility will apply universally to all taxpayers, including those with non-standard balance dates. - Scope
No changes are proposed regarding the types of properties and taxpayers subject to interest limitation rules, ensuring continuity. The interposed entity and other anti-avoidance rules will continue to apply while the interest limitation rules are being phased out. - Deductions on Sale
Rules allowing deductions for disallowed interest upon property sale will continue. This means that where a sale of the property is taxed, the denied interest can be added to the cost of the property and taxed on sale (subject to loss ring-fencing). From a practical perspective you may wish to consider capitalising the denied interest each year so that this is tracked in the financial statements. - Effective date
The proposed interest limitation phasing rules will apply based on interest incurred for the period 1 April to 31 March each year. For most taxpayers this will be the same as their income year. However, for taxpayers with non-standard balance dates they will need to calculate the denied interest for each part of the income year.
Although somewhat controversial in the media, the proposed amendments merely reinstate the same right to deduct interest that every other taxpayer in business has.
