Should You Transfer Your Buy-to-Let to a Limited Company in 2026?

The question of whether to hold rental properties personally or through a limited company has become one of the most pressing issues for UK landlords. With rising interest rates, the end of mortgage interest relief for individuals, and changes to Capital Gains Tax (CGT), many property owners are reassessing their structure.

For some, incorporation offers clear tax advantages. For others, it may introduce unnecessary complexity or cost. The right answer depends on your income, investment goals, and future plans.

This article outlines the key tax differences between individual and company ownership, how incorporation works in practice, and when transferring your buy-to-let to a limited company in 2026 might — or might not — make sense.

1. Why Are Landlords Considering Limited Companies?

Several tax and market changes have driven landlords to look at limited company structures more seriously:

Mortgage Interest Relief Restriction

Since April 2020, individual landlords can no longer deduct mortgage interest from rental income. Instead, they receive a basic rate (20%) tax credit. This means:

• Higher-rate (40%) and additional-rate (45%) taxpayers pay tax on gross rental income, not profit.
• For many, this dramatically increases their tax bill and distorts cash flow.

Limited companies are not affected — they can still deduct mortgage interest in full as a business expense against rental income.

CGT Rates on Property

As of 2025/26:

• Individuals pay CGT at 18% (basic rate) and 24% (higher rate) on residential property gains.
• Companies don’t pay CGT — they pay corporation tax on capital gains, typically at 19% to 25%, depending on profit levels.

This difference may not always favour one side clearly, but for landlords planning to retain properties long-term, the ability to deduct full costs in a company can outweigh slightly higher tax on sale.

Stamp Duty and Surcharges

Buy-to-let properties purchased by individuals or companies are both subject to the 3% additional SDLT surcharge.

However, companies buying multiple properties can sometimes qualify for Multiple Dwellings Relief or plan more efficiently for large-scale acquisitions.

3. Incorporation: What Does It Actually Involve?

You can’t just move a property from your name into a company without consequences.

Transferring a personally held buy-to-let into a limited company is treated by HMRC as a sale at market value, even if no money changes hands.

This means:

• Capital Gains Tax may apply, based on the property’s increase in value since purchase.
• Stamp Duty Land Tax (SDLT) is payable by the company, based on market value plus 3% surcharge.
• A new mortgage may be required, as most lenders will not allow transfers without refinancing.

This creates upfront costs — and sometimes significant tax liabilities — that must be considered before proceeding.

4. Can You Avoid CGT and SDLT on Transfer?

Incorporation reliefs may be available, but only in specific cases.

Section 162 Incorporation Relief (Capital Gains)

This relief can defer CGT on the transfer of a property business to a company, by rolling the gain into the value of the shares received. To qualify:

• The landlord must operate as a business, not just as a passive investor
• There must be significant involvement: regular management, tenant interaction, etc.
• All assets (usually all properties) must be transferred to the company

Note: HMRC has challenged relief where the landlord’s activity is limited — e.g. a single let, or little day-to-day involvement.

SDLT Relief

There is no direct SDLT relief on incorporation — but if you operate through a partnership, there may be a way to reduce or avoid SDLT using the partnership to company rules.

This requires:

• A genuine partnership with accounts and joint decision-making (not just co-ownership)
• At least three years of operation before incorporation

Professional advice is essential if trying to rely on either of these reliefs.

5. When Is It Worth Incorporating?

In general, incorporation may be worth considering if:

• You are a higher-rate taxpayer
• You plan to retain profits in the company for reinvestment (not extract them immediately)
• You are acquiring additional properties or scaling up
• You want to fully deduct mortgage interest
• Your exit strategy doesn’t require pulling out capital personally in the near term

It may not be suitable if:

• You own only one or two properties and do not plan to expand
• You rely on rental income for personal use
• You would incur high CGT or SDLT costs on transfer
• Your tax band is likely to remain basic rate, where the benefit is smaller

---

6. What About New Purchases?

If you are acquiring a new buy-to-let in 2026, the analysis is different.

You won’t face CGT or SDLT on an existing transfer — so incorporation becomes more attractive.

Points to consider:

• Buying in a company allows full interest relief and flat-rate corporation tax
• The downside is double taxation when extracting income or selling
• Using a family investment company structure can help with long-term estate planning

For long-term portfolio growth, many landlords now buy new properties in a company, even if their existing ones remain in personal ownership.

7. Common Mistakes to Avoid

• Assuming incorporation is tax-free — it’s not unless specific reliefs apply
• Transferring property without refinancing or lender approval
• Ignoring future income extraction costs (dividends, salary)
• Using incorporation solely for perceived “loopholes” without proper structure

---

Summary

Incorporating a buy-to-let business can provide significant tax relief — particularly for higher-rate taxpayers — but it must be carefully evaluated. The loss of mortgage interest deductibility for individuals is a key driver, but capital costs, refinancing issues, and future dividend taxation must all be factored in.

A one-size-fits-all approach does not apply. What works for a growing portfolio may be overkill for a small landlord.

Before transferring any property to a limited company, ensure you’ve:

• Calculated the CGT and SDLT exposure
• Checked whether incorporation relief applies
• Reviewed mortgage implications
• Considered how and when you need access to the profits
• Modelled both income and exit strategies over 5–10 years

This is a long-term decision — and it’s one that should always be made with professional advice.
