HMRC’s Expanding Enforcement Measures Against Tax Evasion

As buy-to-let incorporation rises, HM Revenue & Customs (HMRC) is increasing its focus on tax evasion and avoidance schemes within the property sector.

Landlords must be aware of HMRC’s key enforcement actions and compliance initiatives that may impact their tax liabilities.

Increased Capital Gains Tax (CGT) Investigations

One of the major areas of HMRC’s scrutiny is Capital Gains Tax (CGT) compliance. When landlords transfer properties to a limited company, they trigger a CGT liability based on the property’s market value at the time of incorporation. Many landlords have attempted to avoid this liability through complex restructuring strategies. HMRC is actively investigating cases where:

• CGT has been underreported or misdeclared during incorporation.
• Artificial transactions have been used to suppress market valuations.
• Landlords have failed to report property disposals properly.

With over 14,000 CGT investigations completed in 2023-24, landlords should ensure they follow the correct valuation and reporting procedures to avoid penalties.

Crackdown on Buy-to-Let Tax Avoidance Schemes

Tax avoidance schemes designed to minimize landlords’ tax liabilities have become a prime target for HMRC.

A notable example is the “Less Tax for Landlords” scheme, which encouraged landlords to shift properties into partnerships and corporate structures to reduce tax exposure.

HMRC has challenged the validity of such schemes and imposed significant tax penalties on those found to be non-compliant.

Key Red Flags in Tax Avoidance Schemes

Landlords should be cautious of schemes that:

• Promise unrealistic tax reductions through artificial structures.
• Involve circular transactions designed purely for tax benefits.
• Lack of genuine commercial purpose beyond tax savings.

Those who have participated in such schemes may face backdated tax liabilities, interest, and financial penalties. Seeking professional tax advice is essential to assess exposure to HMRC enforcement.

Targeting Undeclared Rental Income

Under the Let Property Campaign, HMRC is encouraging landlords to voluntarily disclose any previously undeclared rental income. Failure to report rental income accurately can result in severe penalties, including fines of up to 100% of unpaid tax. The key aspects of this initiative include:

• Encouraging voluntary disclosures to reduce penalties.
• Identifying landlords through data analysis, including mortgage lender records, land registry data, and tenant deposit schemes.
• Issuing compliance letters and conducting audits on landlords with suspected unreported income.

Mortgage Interest Deduction Rules: What Landlords Need to Know

Since the 2017 tax changes, individual landlords can no longer fully deduct mortgage interest from rental income when calculating taxable profits. Instead, they receive a 20% tax credit, which can be less beneficial for higher-rate taxpayers. In contrast, limited companies can still deduct mortgage interest as a business expense, making incorporation a more tax-efficient strategy for many landlords.

However, landlords must weigh the corporate tax implications, administrative costs, and potential exit strategy complexities before transitioning to a company structure.

Financial and Legal Considerations for Landlords in 2025

Landlords must navigate a complex tax and regulatory landscape. The following financial and legal aspects should be carefully evaluated:

Stamp Duty Land Tax (SDLT) on Incorporation

Stamp Duty Land Tax (SDLT) applies when transferring properties to a company, potentially increasing upfront costs. However, landlords with large portfolios may qualify for incorporation relief under certain conditions.

Dividend Taxation for Limited Companies

While operating through a company provides tax advantages on mortgage interest deductions, withdrawn profits are subject to dividend taxation.

With recent increases in dividend tax rates, landlords need to assess whether retaining profits within the company aligns with their long-term financial goals.

Inheritance Tax (IHT) and Estate Planning

Owning properties through a company structure offers potential inheritance tax planning opportunities.

Shares in a company may be structured to facilitate tax-efficient succession planning, whereas personally held properties could be subject to a 40% IHT charge above the tax-free threshold.

Future Outlook: Potential Regulatory Changes for Landlords

The UK government is continuously reviewing tax policies affecting landlords. Possible future reforms may include:

• Further tightening of corporate tax loopholes to prevent tax avoidance via buy-to-let companies.
• Adjustments to mortgage interest relief to level the playing field between individual and corporate landlords.
• Stronger enforcement of CGT compliance to ensure accurate reporting on property disposals.

Given these potential changes, landlords should stay informed and adapt their tax strategies accordingly.

Final Recommendations: Ensuring Compliance and Maximising Tax Efficiency

To mitigate risks and optimize tax efficiency, landlords should consider the following steps:

1. Seek professional tax advice to navigate complex regulations and avoid unintended tax liabilities.
2. Ensure full compliance with CGT and SDLT rules when incorporating properties into a limited company.
3. Avoid high-risk tax avoidance schemes that could result in backdated liabilities and financial penalties.
4. Regularly review tax planning strategies in light of evolving government policies.

FAQ on Buy-to-Let Incorporation and HMRC Scrutiny

Why are landlords incorporating buy-to-let properties into companies?

Landlords are incorporating their buy-to-let properties to benefit from tax advantages, such as:

• The ability to deduct mortgage interest as a business expense.
• Lower corporation tax rates compared to higher personal income tax rates.
• Flexible tax planning, such as income splitting among shareholders.

How does incorporation affect Capital Gains Tax (CGT)?

When transferring a property from personal ownership to a limited company, the transaction is treated as a sale at market value, which may trigger a Capital Gains Tax (CGT) liability. Landlords need to account for CGT based on the property’s appreciation since purchase.

Do landlords have to pay Stamp Duty Land Tax (SDLT) when incorporating?

Yes, when a property is transferred to a company, Stamp Duty Land Tax (SDLT) is usually payable. However, landlords with multiple properties may qualify for incorporation relief under specific conditions.

How is rental income taxed for limited companies compared to individual landlords?

• Individual landlords: Pay income tax on rental profits, with tax rates up to 45% for high earners.
• Limited companies: Pay corporation tax on rental profits (currently 19%-25%, depending on profits). If profits are withdrawn as dividends, additional dividend tax rates apply.

What tax advantages do limited companies have over individual landlords?

Limited companies benefit from:

• Full mortgage interest relief, reducing taxable profits.
• Lower corporation tax rates (compared to higher personal tax brackets).
• Retaining profits within the company for reinvestment.

However, withdrawing profits from the company as dividends may result in additional tax charges.

Is incorporating a buy-to-let portfolio always beneficial?

Not always. Incorporation involves:

• CGT and SDLT costs, which can be significant.
• Additional administrative and accounting responsibilities.
• Dividend tax on withdrawals, which can reduce overall tax savings. It is advisable to consult a tax specialist before incorporating.

How is HMRC cracking down on buy-to-let tax avoidance?

HMRC is increasing investigations into:

• CGT underreporting during property transfers to companies.
• Tax avoidance schemes, such as those marketed under “Less Tax for Landlords.”
• Undeclared rental income, using data matching from lenders, land registries, and tenant deposit schemes.

What is the HMRC Let Property Campaign?

The Let Property Campaign is an HMRC initiative encouraging landlords to voluntarily disclose undeclared rental income. Those who come forward may receive reduced penalties, while landlords caught through investigations may face heavier fines.

Are landlords who use tax avoidance schemes at risk?

Yes. HMRC is aggressively challenging schemes designed to artificially reduce tax liabilities. Landlords who engage in such schemes may:

• Owe backdated taxes plus interest.
• Face penalties for tax avoidance.
• Be required to unwind non-compliant corporate structures.

Can landlords switch back from a limited company to personal ownership?

Yes, but this process may trigger CGT, SDLT, and administrative costs. Landlords should consider the long-term tax implications before incorporating their property portfolio.

What are the risks of HMRC investigations for landlords?

Landlords found to be non-compliant with tax laws may face:

• Hefty financial penalties.
• Retrospective tax bills for unpaid CGT, SDLT, or rental income tax.
• Legal action in cases of deliberate tax evasion.

What should landlords do to remain tax-compliant?

• Accurately report rental income and CGT liabilities.
• Avoid aggressive tax avoidance schemes flagged by HMRC.
• Seek professional tax advice to ensure compliance and optimize tax efficiency.

Is the government likely to introduce further tax reforms for landlords?

The UK government regularly reviews tax policies, and further changes may include:

• Tighter restrictions on mortgage interest relief.
• Revised CGT rules for buy-to-let investors.
• Higher compliance requirements for landlords operating via limited companies.

What are the next steps for landlords considering incorporation?

Before incorporating a buy-to-let portfolio, landlords should:

1. Assess tax liabilities, including CGT and SDLT.
2. Calculate long-term tax savings versus administrative costs.
3. Consult with a property tax specialist to ensure the best financial strategy.

Conclusion

Incorporating a buy-to-let portfolio can offer significant tax advantages, but it also comes with regulatory complexities and risks.

With HMRC intensifying scrutiny on tax compliance, landlords must ensure full legal adherence while strategically managing their property investments.
