Should you incorporate a buy-to-let portfolio? Test the transfer before comparing annual tax rates.

Incorporation may improve how future profits are retained, but the existing properties must first move to the company. CGT, SDLT, refinancing and legal cost can outweigh an attractive annual tax comparison.

1. Separate the reason from the marketed solution

Clarify whether the aim is reinvestment, borrowing, succession, administration or current income. If most profits must be withdrawn for living costs, a corporate retention model may have less value. If future acquisitions drive the plan, transferring existing property may be unnecessary.

2. Compare annual cash after every layer

Model rent, operating costs, interest, tax, loan repayment and extraction. A company may receive a corporation-tax deduction for qualifying interest and retain post-tax profits, but owners can face further tax when value is extracted.

Use realistic mortgage pricing and fees for the company, not the existing personal borrowing rate.

3. Treat the transfer as a CGT disposal

A connected company generally acquires property at market value for capital-gains purposes. Incorporation relief may defer gains where a business is transferred as a going concern with all relevant assets in exchange wholly or partly for shares.

Property letting ranges from passive investment to an organised business. There is no guaranteed hours threshold. Record the nature, continuity and extent of owner activity and the role of agents.

4. Analyse SDLT independently

CGT incorporation relief does not create SDLT relief. Connected-company and debt rules can charge SDLT on value even where little cash changes hands.

The partnership code may produce a different calculation only where a genuine partnership exists and the detailed statutory conditions are met. Joint ownership, a tax return label or a newly written agreement cannot by themselves create the necessary history.

5. Confirm refinancing before final advice

Identify each mortgage, security, early repayment charge and lender condition. Obtain indicative company terms and check whether personal guarantees remain.

The tax sequence must match the legal and banking completion. A plan that assumes debt transfers without lender agreement is not implementable.

6. Reconcile shares, debt and director’s loan

The company’s consideration may comprise shares and other amounts, including assumed liabilities or a genuine loan balance. That split affects relief and future access to cash.

Legal documents, valuation, tax calculation and accounting entries must describe the same transaction. Do not begin with a desired director’s loan and work backwards.

7. Model life inside and outside the company

Include annual accounts, corporation tax, extraction, property sales, refinancing, death, gifts and a possible sale or winding up. Shares rather than properties become the owners’ personal asset, which changes succession and exit mechanics.

Useful comparison: leave existing property personally owned, acquire only future property in a company, or transfer some or all of the existing business. Each route deserves its own cash-and-tax model.

Frequently asked questions

Can I sell the portfolio to my company at the original cost?

Connected-party market-value rules can apply for CGT, while SDLT can use market value or debt-related consideration. The stated contract price does not control every tax.

Is there an hours test for CGT incorporation relief?

No fixed statutory number guarantees business status. The nature, extent, regularity and organisation of the owner’s activities must be assessed from real evidence.

Does joint ownership prove a property partnership?

No. Co-ownership and a partnership are not the same. Conduct, profit sharing, business relationship, records and legal evidence all matter for the SDLT partnership code.

Can a director’s loan equal the full property value?

Not automatically. The consideration, debt, shares, relief computation and accounting entries must reflect the actual legal transaction. An unsupported credit can undermine the analysis.

Will lenders allow the transfer?

Existing loans normally need consent or refinancing. Company rates, guarantees, early repayment charges and loan-to-value limits belong in the decision model.

Could I incorporate only future purchases?

Yes, future acquisitions can use a different route from existing property. A split approach may avoid unnecessary transfer taxes while still supporting long-term reinvestment.

Apply the framework to your own facts before acting.

A focused consultation can test the commercial objective, identify the facts that change the tax result and define any further written or implementation work.
