Should I Stay or Should I Go?

A Comprehensive Guide to the 2025–2028 Tax Changes and the Future for Landlords

The Autumn Budget delivered one of the most significant shifts in landlord taxation in a decade. Combined with the incoming changes under the Renters Reform Bill, the next three years will reshape the private rented sector (PRS) more fundamentally than any period since the introduction of Section 24.

For landlords, the challenge is no longer simply managing rising costs.
It is understanding a new tax framework, assessing portfolio resilience, and determining whether staying in the sector — or exiting — is the right financial decision.

This long-form analysis provides a clear, professional interpretation of the changes affecting landlords between now and 2028. It outlines the implications, risks, opportunities, and strategic decisions landlords must make to remain profitable and compliant in an evolving landscape.

1. Overview: A New Era for UK Landlords

The latest Budget goes beyond incremental changes. It introduces:

A new rental income tax regime, adding +2 percentage points to property income tax from April 2027.
Higher dividend taxes for company-structure landlords from April 2026.
Higher taxation on savings income from April 2027.
A prolonged freeze on personal tax thresholds until 2031, the longest in modern UK history.
The continuation of Section 24, preventing mortgage interest relief for personal landlords.
A new high-value property council-tax surcharge from 2028.
No changes to Stamp Duty, meaning acquisition costs remain high.
Rising compliance expectations tied to the Renters Reform Bill.

These changes collectively shift the PRS towards professionalisation. Casual, accidental, or highly leveraged landlords face growing pressure. At the same time, demand for rental property continues to rise due to limited supply, making the sector increasingly favourable for well-structured, prepared, and long-term investors.

The central question, then, is no longer whether the PRS is viable — it is whether your specific portfolio, in its current form, can remain viable under the new system.

2. All Budget Changes That Affect Landlords (2025–2028)

Below is a summary of all relevant policy changes — direct and indirect — now baked into the 2025–2028 tax horizon.

2.1 From April 2027: New Higher Tax Rates on Rental Income

The most consequential change is the creation of new property income tax rates, set at:

22% basic rate
42% higher rate
47% additional rate

This represents a 2 percentage point increase on each band compared to employment income.

These apply only to rental income, meaning landlords face a higher tax burden than other income groups.

Combined with Section 24, this will sharply reduce net profit for personal-name landlords with high mortgage costs or weak yields.

2.2 From April 2026: Dividend Tax Rise (+2%)

Landlords using limited companies will face higher personal taxation when extracting profit, with dividend taxes rising across all bands.

Despite this, companies remain significantly more tax-efficient for higher-rate landlords due to:

Full mortgage interest deductibility
Lower corporation tax
Flexible profit extraction options

This change narrows — but does not close — the gap between personal and corporate ownership.

2.3 From April 2027: Savings Income Tax Rise (+2%)

Any interest earned on savings, including maintenance reserves or property sale proceeds, will be taxed 2% higher.

Landlords holding large cash buffers or reserves should be aware of reduced net returns.

2.4 Threshold Freezes Until 2031

The freeze on:

Personal Allowance
Basic rate threshold
Higher rate threshold
Additional rate threshold

…means “fiscal drag” will pull more landlords into higher tax bands.

As rents rise with market pressures, landlords’ taxable income will increase even if real profitability does not.

2.5 No Change to Stamp Duty

All existing Stamp Duty rules remain in place, including the 3% additional property surcharge.

This continues to make expansion costly for personal-name landlords and reinforces the long-term case for using limited companies.

2.6 Capital Gains Tax (CGT) Allowance Fixed at £3,000

The reduced allowance significantly increases CGT liabilities when disposing of rental property.

Landlords planning to sell to reduce exposure should model their CGT position early to avoid surprises.

2.7 No Changes to Section 24

Mortgage interest remains fully non-deductible for personal-name landlords.

This remains the single biggest driver of reduced profitability for leveraged individuals in the PRS.

2.8 From 2028: High-Value Property Surcharge

Council tax for properties valued over £2m will increase.
This affects investors in prime areas and may alter the economics of high-value rental units.

2.9 Compliance and Regulatory Pressure Continues to Rise

Alongside tax changes, landlords face:

Strengthened tenant protections
Increased enforcement funding
Further development of future EPC rules
Longer-term movement towards decarbonisation in housing stock

These changes create additional administrative and cost pressures, particularly for landlords with older properties.

3. The Renters Reform Bill: Its Impact on Profitability and Rent Increases

A critical part of the “stay or go” decision is understanding how rent increases work under the Renters Reform Bill.

There is significant confusion in the sector, but the core facts are:

3.1 Landlords Retain the Right to Increase Rent Annually

Under the new rules, landlords may:

Increase rent once every 12 months
Use the updated Section 13 process
Set the rent at prevailing market rates

This is unchanged from the current system.

3.2 There Are No Rent Caps Under the Bill

The Bill does not introduce:

Rent controls
CPI-only increases
Linking rent to wages or affordability
Rent freezes
Regional caps

The only test is whether the rent reflects market value.

This gives landlords continued pricing power in areas where supply is tight — which is increasingly common across the UK.

3.3 Tenants May Challenge Increases, but Only on Reasonableness

The First-tier Tribunal can review increases.

However, tribunals assess rent based on:

Comparable local properties
Market evidence
Property condition

They do not impose political or affordability caps.

For well-maintained properties with reasonable increases, challenges are rare and seldom successful.

3.4 The Effect: Annual, Market-Based Rent Growth Sustains Viability

This ability to maintain market-aligned rent levels is central to the argument that landlords can remain profitable even under the new tax regime.

As long as rent increases are:

documented
reasonable
evidence-based
communicated professionally

…the Renters Reform Bill does not prevent sustainable long-term rent growth.

4. Should You Sell? A Rational Assessment

Selling can be the right decision, but it must be based on:

Real net profitability
Future tax projections
Property condition and capex forecasts
Location-specific supply and demand
Your long-term goals

Selling is most rational for landlords with:

High-LTV mortgages
Marginal or negative cashflow
Old, high-maintenance properties
Low rental demand areas
No appetite for the increased compliance burden
Personal financial priorities outside property

These landlords may achieve better overall financial outcomes by reallocating capital elsewhere.

5. Why Many Landlords Should Stay (And Will Profit From Staying)

Despite the increased tax burden, there are strong reasons why staying in the sector may be the optimal financial decision.

5.1 Demand for Rental Property Continues to Grow

The UK has a severe structural shortage of rental homes.

Factors include:

Decades of under-building
Affordability barriers to home ownership
Population growth
Landlord exits reducing supply

This imbalance underpins long-term rent growth.

5.2 Market-Aligned Rent Increases Remain Legal

As outlined earlier, the Renters Reform Bill allows:

Annual increases
Market-based adjustments
Transparent, evidence-driven rent reviews

With fewer landlords in the market, rents are forecast to continue rising in most regions.

5.3 Portfolio Landlords Remain Resilient

Landlords with multiple properties benefit from:

Economies of scale
Lower void risk
Diversification
Better access to finance
Stronger negotiating power
Easier restructuring options

These landlords are well placed to withstand tax increases.

5.4 Property Remains a Strong Long-Term Asset

Historically, property investment has:

Provided inflation-beating returns
Delivered stable income
Offered capital appreciation
Served as a hedge against market volatility

The core fundamentals remain unchanged.

5.5 Staying Allows Time to Restructure

Between now and 2027, landlords can:

Refinance
Incorporate
Prune weak units
Strengthen reserves
Improve EPC rating
Optimise operational efficiency

A well-managed portfolio will weather the upcoming tax changes far better than a passive or neglected one.

6. The Smart Middle Strategy: Restructure, Don’t React

Most landlords should neither panic-sell nor passively hold.

A professional approach includes:

6.1 Sell Weak or Underperforming Units

Dispose of properties that:

Have persistently low yields
Attract problematic tenants
Require large amounts of capital expenditure
Sit outside core, high-demand areas
Face EPC upgrade challenges

This strengthens the remaining portfolio.

6.2 Consider Incorporation

Despite higher dividend tax:

Corporation tax remains lower
Mortgage interest is deductible
Profit extraction is flexible
Inheritance planning is improved
Growth is easier to finance

Companies remain a strong long-term structure for serious landlords.

6.3 Refinance Before 2027

Securing longer-term stability is essential as the new rental tax regime approaches.

6.4 Improve Asset Quality

Enhancing property condition and energy efficiency:

Justifies higher rent
Reduces tribunal risk
Cuts long-term operating costs
Protects capital value

This is particularly important under Renters Reform’s strengthened tenant rights.

6.5 Build a Cash Reserve

A strong reserve protects against:

Unexpected repairs
Arrears
Voids
Future rate rises
Tax changes

Three to six months of running costs per property is advisable.

7. The Timeline: What Happens When (2025–2028)

2025 — Planning and Portfolio Assessment

Start modelling profitability and restructuring options.

2026 — Dividend Tax Rises

Make ownership-structure decisions and dispose of underperformers.

2027 — Rental Income Tax Rises

Your portfolio must be fully prepared by this point.

2028 — High-Value Property Surcharge

Prime landlords reassess asset allocation.

8. A Practical Decision Framework: Stay, Sell, or Restructure?

To decide your next step, ask:

1. Is this property profitable after 2027 tax rates?

If yes → keep
If no → consider selling

2. Am I in the most tax-efficient ownership structure for 2027 and beyond?

If no → restructure

3. Do I want to remain a landlord long-term?

If no → exit
If yes → strengthen your portfolio
