Why professional landlords move portfolios out of personal names and into a UK limited company.
BYPASS SECTION 24
100% Tax Deductible Mortgage Interest
The Issue
Personal landlords in the 40%/45% tax brackets are taxed on gross turnover rather than net profit due to Section 24 interest restrictions.
The SPV Fix
Inside a UK Ltd Company (SIC 68209), mortgage interest remains 100% tax-deductible as a business expense against Corporation Tax.
CGT DEFERRAL
Section 162 Incorporation Relief
How it works
Allows landlords transferring a business as a 'going concern' to defer Capital Gains Tax (CGT) by rolling gains into shares issued by the new SPV.
Requirement
Proving active business management — typically 20+ hours per week spent managing the portfolio.
SCHEDULE 15 RULES
Stamp Duty Land Tax (SDLT) Mitigation
How it works
Transferring property to a connected company usually triggers 15% SDLT rates.
The Partnership Route
Transferring via a legitimate property partnership under Schedule 15 SDLT rules can reduce or eliminate the SDLT liability to 0%.
TAX-FREE CAPITAL EXTRACTION
Creating a Director's Loan Account (DLA)
How it works
Net equity transferred into the SPV is credited to your Director's Loan Account (DLA).
The Benefit
You can draw future rental profits or refinanced funds out of the company 100% tax-free until the DLA is repaid in full.
Know the Risks
The 3 Biggest Incorporation Hurdles & How We Clear Them
Incorporation fails on tax qualification, refinance capacity, or anti-avoidance compliance. Here is how each is handled.
1. Qualifying as a 'Business' (S162 Test)
HMRC scrutinises whether your portfolio constitutes a genuine 'business' or a passive investment. Demonstrating active management, multiple properties, and formal bookkeeping is critical for S162 CGT deferral.
2. Refinancing Existing Personal Debt
Mortgages cannot simply be transferred. Lenders must replace your personal mortgages with new SPV Buy-to-Let mortgages. Acorn packages your whole portfolio with specialist lenders who underwrite the transition simultaneously.
3. SDLT Anti-Avoidance Compliance
Forming a partnership solely to avoid SDLT triggers HMRC anti-avoidance rules (GAAR). The partnership must be a genuine, pre-existing commercial entity with commercial trading history.
The Process
The Step-by-Step Incorporation Roadmap
Four coordinated stages, run alongside your tax specialist and conveyancer.
Step 1
Professional Tax & Legal Audit
A chartered tax specialist confirms your Section 162 and SDLT eligibility before anything moves.
Step 2
SPV Incorporation & Valuation
Establish the UK Ltd Company (SIC 68209) and obtain RICS valuations across the portfolio.
Step 3
Portfolio Mortgage Approval
Acorn Finance secures SPV term sheets to refinance the existing personal debt in one coordinated package.
Step 4
Legal Completion & DLA Credit
Conveyancers complete the asset transfers, personal mortgages are cleared, and net equity is credited to your Director's Loan Account.

Personal Income Tax Rate
Illustration assumes an indicative 5.50% average mortgage interest cost, a 20% basic-rate interest credit under Section 24, and Corporation Tax at 25% on net company profit.
Personally you would pay roughly £35,900 a year at the higher rate (40%), versus about £14,875 of Corporation Tax inside the SPV — while £900,000 of equity sits on your DLA to draw back tax-free.
Indicative illustration only, ignoring CGT, SDLT, personal allowances and other income. Actual outcomes depend on your full tax position and must be confirmed by a qualified tax specialist.
Critical Legal, Tax & Financial Advice Notice
Acorn Finance is a specialist credit broker authorised and regulated by the FCA (#660207), not a tax advisory firm, chartered accountant, or legal practice. Incorporating a property portfolio involves complex statutory provisions including Section 162 TCGA 1992 (Incorporation Relief), Schedule 15 FA 2003 (SDLT Partnership rules), and anti-avoidance legislation (GAAR).
We arrange the commercial and SPV mortgage refinancing required to execute the transaction. We do not provide legal or tax advice. You MUST consult a qualified tax specialist or chartered accountant specialising in property incorporation before making any decisions.
