Overview
The tax treatment of the Private Rented Sector (PRS) in England has shifted from a highly benign, unregulated environment designed to stimulate growth after the Housing Act 1988, to a restrictive, heavily taxed sector since 2015/2016. This evolution has seen the sector move from tax-favoured investment to a model where high-rate taxpayers face severely restricted mortgage interest relief, often driving landlords to incorporate or sell.
1. The Post-1988 Boom: Deregulation and Favorable Tax
The Housing Act 1988 (coming into effect January 1989) was the catalyst for the modern PRS, creating Assured Shorthold Tenancies (ASTs), lifting rent controls, and ending long-term security of tenure.
- Tax Climate: Throughout the 1990s and 2000s, this was accompanied by a “markedly benign tax context”.
- Interest Deduction: Individual landlords could deduct 100% of mortgage interest from their rental income before paying income tax. This meant higher-rate (40%+) taxpayers received 40%+ tax relief on their borrowing costs.
- Capital Gains & Wear and Tear: Landlords benefited from generous capital gains treatment and “wear and tear allowance,” which allowed deductions of 10% of rent for furniture replacement without proof of expenditure.
- Impact: Combined with the introduction of buy-to-let mortgages in 1996, this led to a massive expansion of the PRS—the number of households doubled from roughly 2 million in 1980 to over 4.6 million by 2021.
2. The Shift: 2015–2020 (Restrictive Taxation)
From 2015, the government deliberately acted to dampen investor demand for residential property to support first-time buyers.
- Section 24 (Mortgage Interest Restriction): Phased in between 2017 and 2020, this removed the ability for individual landlords to deduct mortgage interest from income. Instead, they receive a flat-rate 20% tax credit. Higher-rate taxpayers now effectively pay tax on turnover, not profit, forcing some into losses.
- Stamp Duty Surcharge (2016): A 3% extra Stamp Duty Land Tax (SDLT) rate was applied to all additional residential properties (buy-to-let or second homes), later increased further to 5%.
- Wear and Tear Allowance Abolished (2016): Replaced by a system where landlords can only claim relief for actual costs incurred.
- Capital Gains Tax (CGT): Residential property sales attract higher CGT rates compared to other assets but they are now aligned with the standard CGT rates for other assets (18% basic/24% higher). An accelerated payment regime requires payment within 60 days of a sale.
3. Current Position (Post-2020)
- Incorporation: Many individual landlords have shifted to Limited Company structures, which are not affected by Section 24 and still pay corporation tax on profits, although this incurs higher operational complexity and capital gains when transferring properties.
- Making Tax Digital (MTD): rules require digital record-keeping and quarterly reporting to HMRC (phased 3 year implementation, starting April 2026) increase the compliance burden.
- Renters Rights Act: Further regulation—including the abolition of Section 21 “no-fault” evictions—coupled with tax changes, has significantly reduced the attractiveness of private individual landlordism. (Starting 6 April 2027, the UK government is increasing Income Tax on rental profits by 2 percentage points.)
Summary of Impact
- Growth Stagnation: The rapid growth of the PRS stalled after 2016; it grew by an average of 200,000 homes a year pre-2016, but only 20,000 annually after, while owner-occupation rebounded.
- Landlord Exodus: Many experienced landlords, particularly higher-rate taxpayers with high-leveraged mortgages, have sold properties, particularly since 2020.
- Rents & Affordability: While critics argued tax changes would increase rents, research indicates that while rents have increased due to high demand, the 2016 tax changes did not significantly increase the average share of income spent on rent by tenants, as landlords often cannot pass on all costs, taking the hit in reduced profit margins.
- Shift to Corporate: The sector is shifting from individual “amateur” landlords to larger corporate entities or limited companies, which can manage the increased tax and regulatory burden.
