SPV & Property Company Structuring
A property SPV (Special Purpose Vehicle) is a limited company holding buy-to-let or property investment assets. The structure is increasingly common in the Harrow market because Section 24 makes personal-name holding tax-inefficient for higher-rate-tax landlords. The accounting is more complex than personal SA — corporation tax computation, director's loan handling, dividend planning, SDLT optimisation including Multiple Dwellings Relief — but the after-tax yield is usually better at portfolio scale. We match you with specialists who handle SPV setup and ongoing compliance.
What SPV & Property Company Structuring Involves
Pre-incorporation analysis is where the work starts. The breakeven between holding personally and incorporating into a SPV depends on portfolio size and finance costs, intended hold period, capital growth versus income strategy, inheritance planning, and refinance timing. Specialist accountants run the breakeven each year for higher-rate-tax landlords. The typical conclusion: at 4+ properties, 70%+ LTV, and 5+ year hold horizons, SPV typically wins on after-tax yield even after the SDLT incorporation cost.
SDLT on incorporation is the biggest single cost. Transferring properties from personal name to a SPV is treated as a sale-and-purchase for SDLT — the 3% second-property surcharge applies to all properties (the SPV is treated as not owning the properties before the transaction). For a £1.5m portfolio, the SDLT bill is typically £80-130k depending on value-band split. Multiple Dwellings Relief can reduce SDLT meaningfully where 2+ dwellings transfer together — specialist accountants run MDR vs straight SDLT comparisons to optimise.
Annual corporation tax computation differs from personal SA. Currently 19% corporation tax up to £50k profits, marginal rate up to £250k, 25% above £250k. Mortgage interest is fully deductible (no Section 24). Dividend distribution to shareholders is taxed at dividend rates (8.75% basic / 33.75% higher / 39.35% additional). For higher-rate-tax landlords with material finance costs, the SPV route's effective tax rate is often 30-35% versus 50%+ for personal holding under Section 24.
Director's loan handling is where SPVs frequently go wrong. Director's loans need interest at the official rate (currently 2.25%) when overdrawn; otherwise HMRC will deem interest charged and tax the company on phantom income. Overdrawn director's loans not repaid within 9 months of year-end attract a 33.75% Section 455 corporation tax charge — repayable when the loan is repaid but a meaningful cash drain in the meantime. Specialist accountants set up loan agreements properly and flag the 9-month deadline proactively.
Dividend timing for higher-rate-tax shareholders is a real annual planning exercise. Drawing dividends to top up income to the £100k threshold (where personal allowance starts tapering) is rarely optimal — the marginal effective rate above £100k can exceed 60% when the tapered allowance is lost. Specialist accountants model the year-end position and advise on the right dividend draw to maximise after-tax income. Generalists frequently leave excess profits in the company without modelling whether the corporation-tax-then-dividend route or the income-as-salary route is better in a given year.
Where SPV Structuring Catches Landlords Out
Multiple Dwellings Relief on SPV incorporation — the relief applies where 2+ dwellings transfer together, treating the average price per dwelling as the basis for SDLT calculation. Can reduce SDLT meaningfully on portfolios with mixed property values. Specialist accountants run MDR vs straight SDLT comparisons; generalists frequently default to per-property SDLT.
Director's loan account interest — when a director borrows from the company (overdrawn DLA), HMRC requires interest at the official rate. Interest charged to the director is corporation tax income for the company; if not charged, HMRC will deem interest charged anyway. Generalists frequently leave the DLA uninterested, creating phantom-income exposure.
Section 455 charge on overdrawn DLAs — overdrawn loans not repaid within 9 months of year-end attract a 33.75% corporation tax charge. The charge is repayable when the loan is repaid, but it's a meaningful cash hit in the meantime. Specialist accountants flag this proactively.
Dividend cover and lender covenants — many property SPV mortgages have covenants requiring minimum dividend cover. Drawing dividends that breach covenants can trigger lender action. Specialist accountants check covenant compliance before signing off on dividends.
CGT on incorporation versus corporation tax on eventual disposal — incorporating triggers CGT at residential property rates (28% on residential gains for higher-rate-tax landlords). The SPV then holds the property at market value (its base cost = transferred market value). On eventual disposal by the SPV, corporation tax applies to the gain at corporation tax rates. The two-stage tax is sometimes worse than holding personally and disposing personally; sometimes better. Specialist accountants model both pathways.
Annual filing deadlines — SPVs file accounts at Companies House within 9 months of year-end, plus a CT600 corporation tax return within 12 months of year-end (paying corporation tax 9 months and 1 day after year-end). Plus an annual confirmation statement. Generalist accountants serving primarily personal-name landlords occasionally miss SPV-specific deadlines.
How SPV Structuring Plays Out
Year 1 SPV setup, 4-property landlord incorporating
Higher-rate-tax landlord with 4 BTL properties incorporating into a new SPV. Portfolio market value £1.45m. Incorporation SDLT after Multiple Dwellings Relief: £62,200 (vs £79,400 without MDR). CGT on personal-side disposal: £42,800 (residential rate at 28%). New SPV base cost: £1.45m. Year 1 SPV operations: gross rents £138k, mortgage interest £41k, repairs and management £24k, depreciation/capital allowances £8k. Corporation tax £12.4k. Director took dividends of £45k to top up other income to £100k boundary. Net effective tax rate on rental income reduced from ~52% (personal-side, post-Section 24) to ~31% (SPV including dividend tax).
Director's loan repayment timing, mid-portfolio SPV
SPV with 7-property Harrow portfolio. Director had drawn £80k from the company across the year as ad-hoc loans (intended to be cleared at year-end against dividends). By year-end, DLA was overdrawn £62k. Modelled the s455 implications: if not repaid within 9 months of year-end, 33.75% × £62k = £20.9k corporation tax charge (refundable on later repayment but a cash drain). Restructured as: declared dividend of £62k clearing the DLA, taxed personally at the dividend higher rate. Net cash effect: £20.9k of s455 charge avoided; ~£21k of dividend tax owed instead. Net positive plus avoiding 9-month timing pressure.
MDR vs straight SDLT on incorporation
Landlord incorporating 5-property portfolio (3 properties at £400k each, 2 properties at £680k each). Total £1.96m. Without MDR: per-property SDLT calculation including 3% surcharge on each = £124,400. With MDR: average price per dwelling = £392k; SDLT calculated on £392k per dwelling × 5 dwellings = £64,200. MDR saving: £60,200. The application is filed alongside the SDLT return; specialist accountants identify and apply MDR; generalists frequently default to per-property without considering MDR.
