Landlords with growing portfolios are making a deliberate shift to limited companies, and the motivation is simple: contain future tax exposure, protect cash flow, and keep growth options open. Since Section 24 restricted finance cost relief for individuals, the sums have changed. Incorporation is now a mainstream strategy rather than a niche move, especially for owners with multiple mortgaged properties who want control over long term planning 1.
Before we go further, a quick explainer. When people say “company structure” here, they usually mean a buy to let SPV
SPV stands for Special Purpose Vehicle, a limited company set up to hold property, ring fencing risk and simplifying mortgage underwriting.

that holds the properties, while the landlord draws funds as salary or dividends. The key difference is how profits and finance costs are taxed. Companies can deduct mortgage interest in full, whereas individuals receive only a basic rate credit on those costs under Section 24.
Why more landlords are incorporating
The tax drivers are clear. The post 2017 finance cost rules, rising interest costs, and the flexibility of corporate profit extraction create a strong case for many multi property owners 1. Add the ability to retain profits for future purchases, and the appeal grows further.
- Full interest deductibility inside a company: Corporation tax is charged on profit after mortgage interest. For individuals, Section 24 provides only a credit at the basic rate, which can inflate taxable income and push you into higher tax bands.
- Flexible profit extraction: Directors can use a blend of modest salary and dividends, plus pension contributions, to match personal allowances and bands. This gives fine grained control over take home pay.
- Retain and reinvest profits: Leaving profits in the company to fund deposits or refurbishments can accelerate growth without personal tax leakage each year.
- Estate and succession planning: Shares can be gifted or transferred more flexibly than bricks and mortar, offering tools for long term family planning.
- Professional presentation to lenders: Many specialist lenders now prefer SPVs. Pricing can be competitive, and underwriting is often streamlined for simple property holding companies.
Market data backs up the trend. Research suggests a meaningful minority of landlords operate within a company already, and that share is rising 2. At the same time, a significant cohort has exited the market, a reminder that margins can be tight without the right structure 3.
What changes when you use a limited company
Two things stand out: how profits are taxed, and how cash leaves the structure. Inside a company, profit after allowable costs, including finance, is charged to corporation tax. Cash extraction then follows as salary, dividends, or pensions. The total tax can be lower or higher depending on gearing, personal income, and growth plans. High loan to value portfolios often see the biggest savings.
From a compliance perspective, expect director duties, Companies House filings, and formal accounts. The upside is cleaner records, better analytics via modern software, and a professional image with banks. Pennine Accounting integrates Xero from day one so you can track cash flow, taxes due, and loan covenants in real time.

Costs, taxes, and pitfalls to map out first
Incorporation is not free. You need to model stamp duty land tax on property transfers, potential capital gains tax triggers, lender consent, legal fees, and new company running costs. Reliefs may be available in specific circumstances, for instance partnership incorporation routes
Where a genuine partnership exists, different SDLT rules may apply. Evidence of partnership is critical, including accounts and history.
Read guidance
. Good records strengthen your position if you are claiming reliefs.
There is also the practical question of mortgages. Some lenders will not permit novation to a company, so refinancing can be required. Rates may differ, product fees can be chunky, and legal work adds time. A clear sequence plan avoids voids and rushed decisions.
Five practical steps to explore incorporation
Use this as a framing exercise before you engage lenders and solicitors.
Build a clean, current portfolio model
List each property with rent, costs, mortgage details, and current value. Add personal income. Create a base case and a company case to compare tax and cash flow for the next five years.
Assess tax triggers and relief routes
Work through CGT, SDLT, and whether you meet the business threshold
Time spent managing, the scale of activity, and services provided can evidence a business rather than passive investment.
See criteria
. Consider whether incorporation relief could apply, and document evidence.
Line up finance and lender consents
Speak with a broker who understands SPV lending. Confirm refinance options, indicative pricing, and timing. Sequencing matters to avoid cash squeezes.
Incorporate the SPV and set up bookkeeping
Choose simple SIC codes, open a business bank account, and implement Xero. Accurate opening balances and legal documents are essential for clean audit trails.
Move properties across with legal support
Work with solicitors on transfers, lender covenants, and any group relief claims. Update insurance and register changes with all stakeholders promptly.
Who tends to benefit the most
Heavily mortgaged portfolios
Where interest is a large share of costs, corporation tax after full interest deduction often beats personal tax with a basic rate credit. Many landlords aim to retain profits in the company, buy the next property from retained earnings, and draw modestly.
Owners planning long term growth
Those reinvesting for ten or more years value the control over timing. Company structures make it easier to smooth personal income, manage allowances, and plan family shareholdings.
