The UK property tax landscape is about to shift dramatically. From April 2027, property income will be taxed at separate rates — 22% for basic rate taxpayers, 42% for higher rate, and 47% for additional rate. This represents a fundamental change from current income tax rates and significantly alters the 2027 tax rates incorporation decision for UK landlords.

Currently, many landlords weigh incorporation against a 19% corporation tax rate versus their marginal income tax rate (20%, 40%, or 45%). From 2027, even basic rate taxpayers will face a 22% rate on property income — higher than the small profits corporation tax rate.

What Are the New 2027 Property Tax Rates?

From 6 April 2027, property income will be subject to these dedicated rates:

  • 22% basic rate (currently 20% general income tax rate)
  • 42% higher rate (currently 40% general income tax rate)
  • 47% additional rate (currently 45% general income tax rate)

These rates apply to rental income after allowable deductions but before Section 24 restrictions on mortgage interest relief. The personal allowance (£12,570 in 2026/27) still applies to total income, including property income.

Meanwhile, corporation tax rates remain at 19% for small profits (up to £250,000) and 25% for profits above £250,000. This creates a clearer tax differential than ever before.

How Does This Change the Incorporation Decision?

The 22% basic rate vs corporation tax comparison now favours corporate ownership even for smaller landlords. Previously, basic rate taxpayers paid the same 20% rate personally as they would through a company (before extraction costs).

Here's how the math changes for different taxpayer profiles:

Basic Rate Taxpayers

A landlord earning £35,000 from employment plus £15,000 rental profit would face:

  • Personal ownership: 22% on rental income = £3,300 tax
  • Corporate ownership: 19% corporation tax = £2,850, plus extraction costs

The 3% differential (22% vs 19%) creates a meaningful saving, even after accounting for dividend tax and additional compliance costs. This is a significant change from the current position where rates are broadly equivalent.

Higher Rate Taxpayers

For higher rate taxpayers, the case becomes even stronger. A landlord with £60,000 employment income and £20,000 rental profit would see:

  • Personal ownership: 42% on rental income = £8,400 tax
  • Corporate ownership: 19% corporation tax = £3,800

Even after dividend extraction at 33.75% (higher rate dividend tax), the corporate structure delivers substantial savings.

Should You Incorporate Before 2027?

The question of whether to incorporate before 2027 depends on several factors beyond just the headline tax rates:

Capital Gains Tax Implications

Incorporating existing properties triggers an immediate CGT liability at 18% (basic rate) or 24% (higher rate). You need to weigh this upfront cost against future tax savings.

For a property portfolio with £100,000 in unrealized gains, a higher rate taxpayer would face £24,000 in CGT to incorporate. The annual tax saving from the new rates needs to exceed this cost within a reasonable timeframe.

Section 24 Mortgage Interest Relief

The Section 24 restrictions continue to apply to personal ownership, limiting mortgage interest relief to a 20% tax credit (reducing to 22% from 2027). Companies can still deduct mortgage interest as a business expense against corporation tax.

For highly leveraged portfolios, this creates an additional advantage for corporate ownership, particularly when combined with the higher property income tax rates.

Timing Considerations for Incorporation

If you're considering incorporation, timing matters for several reasons:

Current vs Future Tax Rates

Incorporating in the 2025/26 or 2026/27 tax years means paying CGT at current rates but potentially qualifying for lower corporation tax on rental profits immediately. However, the full benefit only materializes from April 2027.

Portfolio Growth

If you're actively acquiring properties, incorporating before 2027 means new acquisitions avoid personal ownership from the start. This is particularly relevant given the 5% SDLT surcharge on additional residential properties, which applies equally to companies and individuals.

Making Tax Digital Compliance

From April 2026, Making Tax Digital becomes mandatory for landlords with gross rental income over £10,000. Companies are already subject to MTD for corporation tax, so incorporating might simplify compliance obligations.

Other Factors in the 2027 Incorporation Decision

Dividend Extraction Strategies

The optimal extraction strategy becomes more nuanced with the new property income tax rates. For basic rate taxpayers, the dividend ordinary rate of 8.75% means total effective tax (corporation tax plus dividend tax) of approximately 26% — still higher than the 22% personal rate.

However, companies offer more flexibility in timing distributions, potentially allowing income smoothing across tax years or deferring extractions until retirement when personal tax rates may be lower.

Business Rates vs Council Tax

Corporate ownership may trigger business rates liability instead of council tax on rental properties. For larger portfolios, this could represent a significant additional cost that needs factoring into the incorporation decision.

Inheritance Tax Planning

Company shares may qualify for Business Property Relief, potentially reducing inheritance tax liability to zero. This estate planning benefit becomes more valuable for larger portfolios, particularly when combined with the income tax savings from 2027.

Practical Steps for Landlords Considering Incorporation

Given the scale of change coming in 2027, landlords should take practical steps now:

Calculate Your Specific Position

Work out your projected tax liability under both personal and corporate ownership scenarios. Include CGT on incorporation, ongoing compliance costs, and extraction tax to get a complete picture.

Consider using professional tax calculators or engaging a specialist property accountant to model different scenarios accurately.

Review Your Property Strategy

The 2027 changes may influence your overall property investment approach. If you're planning significant expansion, corporate ownership from the outset might be more tax-efficient than incorporating later.

Consider Partial Incorporation

You don't have to incorporate your entire portfolio. Some landlords choose to incorporate only their highest-yielding properties or those with the lowest CGT liability, maintaining personal ownership of others.

Professional Advice and Implementation

The complexity of the 2027 tax rate changes, combined with individual circumstances around CGT, mortgage arrangements, and long-term strategy, makes professional advice essential.

Key considerations for your adviser discussion include:

  • CGT calculations on your specific property portfolio
  • Mortgage transferability to a corporate structure
  • Optimal timing for incorporation and property transfers
  • Ongoing compliance and administrative costs
  • Estate planning implications of corporate vs personal ownership

The right property accountant will model multiple scenarios and help you understand the long-term implications of different approaches.

Key Takeaways on 2027 Tax Rate Changes

The introduction of separate property income tax rates from April 2027 fundamentally changes the incorporation decision for UK landlords:

  • Even basic rate taxpayers will pay 22% on property income vs 19% corporation tax
  • Higher and additional rate taxpayers face much larger differentials (42%/47% vs 19%/25%)
  • Section 24 mortgage interest restrictions continue to favour corporate ownership
  • Incorporation timing requires careful CGT planning and cash flow analysis

The scale of these changes suggests most portfolio landlords should actively consider their ownership structure before 2027. However, the upfront costs and complexity mean the decision requires careful analysis of your specific circumstances.

Given the significant implications, seeking professional guidance on your 2027 tax rates incorporation decision is likely to be a worthwhile investment in optimizing your property tax position for the years ahead.
