Quick Summary
- Corporation tax (25%) vs Scottish Higher rate (42%) — a limited company saves 17p per pound of rental profit for Scottish Higher-rate landlords, which can be £1,700/year on £10,000 profit
- Section 24 doesn't apply to companies — full mortgage interest deductibility returns inside a limited company, often the biggest financial driver
- Transferring existing properties is expensive — LBTT, 8% ADS, and CGT make moving properties into a company cost £20,000–£60,000+ per property

The limited company question is the most important strategic decision for Scottish buy-to-let investors above the Higher rate threshold. The tax savings are real and significant. The transfer costs are brutal. Here's exactly when incorporation makes sense — and when it doesn't.
Quick Answer: For new Scottish buy-to-let purchases, buying through a limited company (SPV) saves income tax at the purchase stage and keeps full mortgage interest deductibility. For Scottish Higher-rate taxpayers (42%), the annual saving on rental income can be 17–28 percentage points vs personal ownership. But moving existing properties into a company triggers LBTT, 8% ADS, and CGT — easily £20,000–£50,000+ per property. The rule of thumb: incorporate for new purchases, stay personal for existing well-performing properties. Use our Buy-to-Let Tax Calculator to run the numbers for your specific situation.
Why this matters more in Scotland
Scotland's tax system makes the company question more pressing than in England for three reasons:
1. Higher income tax rates. Scotland's 42% Higher rate (vs England's 40%) means the gap between corporate and personal taxation is larger. At 45% (Advanced) and 48% (Top), the gap widens further.
2. Section 24 hits harder. The mortgage interest restriction limits landlords to a 20% basic-rate tax credit. The penalty = (your marginal rate − 20%) × mortgage interest. At 42%, that's 22% × interest. At 45%, it's 25%. A company avoids Section 24 entirely — interest is fully deductible against profits.
3. The ADS creates a higher transfer cost. Moving properties into a company is an ADS-triggering event at 8% in Scotland (5% in England). On a £200,000 property, that's £16,000 in ADS alone — making transfer significantly more expensive north of the border.
The tax comparison side by side
Let's model the same property under both structures.
Scenario: Scottish landlord, combined salary + rental income puts them in the 42% Higher band. One buy-to-let property: £200,000 value, £10,000 annual rent, £5,000 mortgage interest, £2,000 other expenses.
Personal ownership (Scottish Higher rate)
| Item | Amount |
|---|---|
| Rental income | £10,000 |
| Allowable expenses (excl. mortgage) | −£2,000 |
| Taxable profit | £8,000 |
| Income tax at 42% | £3,360 |
| Section 24 credit (20% × £5,000) | −£1,000 |
| Net tax on rental | £2,360 |
| Cash profit (rent − mortgage − expenses) | £3,000 |
| After-tax cash position | £640 |
Limited company (SPV)
| Item | Amount |
|---|---|
| Rental income | £10,000 |
| Mortgage interest (deductible) | −£5,000 |
| Other expenses | −£2,000 |
| Company profit | £3,000 |
| Corporation tax at 25% | £750 |
| Net tax in company | £750 |
| After-tax company profit | £2,250 |
Annual saving vs personal ownership: £1,610 (£2,360 − £750) — on one property.
But this is money inside the company. To take it personally, you pay additional tax when extracting it as salary or dividends.
Extraction comparison
| Extraction method | Tax on £2,250 company profit | Additional tax | Total tax rate |
|---|---|---|---|
| Leave in company | £750 CT | £0 | 25% |
| Take as dividend | £750 CT + 33.75% dividend tax on £2,250 | £759 | ~54% |
| Take as salary | £750 CT + PAYE at 42% + NI | ~£1,700+ | ~67% |
The key insight: the company structure works best when profits stay in the company to fund future purchases. Extracting profits to live on partially erodes the tax saving.

When a limited company makes sense
New purchases by Higher-rate taxpayers
If you're a Scottish Higher (42%), Advanced (45%), or Top (48%) rate taxpayer buying a new BTL property, there's almost always a compelling case for buying through a limited company from the start:
- No transfer costs — you're buying fresh
- Full Section 24 avoidance
- Corporation tax (25%) vs 42–48% income tax
- Mortgage rates: slightly higher for company mortgages, but the tax saving usually more than compensates
- Professional landlord structure: easier to grow a portfolio, access specialist lenders, and eventually exit
The break-even analysis: Company mortgages typically charge 0.5–1% more than personal mortgages. On a £150,000 mortgage, that's £750–£1,500/year extra. The annual tax saving at 42% on typical rental profits usually exceeds this.
Portfolio landlords building a business
If you plan to own multiple properties long-term, a company structure allows:
- Retained profits reinvested into further purchases without personal tax
- Easier access to portfolio mortgage products from specialist lenders
- Cleaner succession planning (company shares can be transferred)
- Clear separation between business and personal assets
Landlords where Section 24 is creating phantom profits
If your mortgage interest is high relative to rent — and Section 24 is creating tax bills on income you never actually receive — incorporation may be the only solution that makes the property viable.
When a limited company doesn't make sense
Moving existing personal properties into a company
This is almost never immediately cost-effective. The transfer costs:
| Transfer cost | On £200,000 property | On £350,000 property |
|---|---|---|
| LBTT (standard) | £1,100 | £9,600 |
| ADS (8%) | £16,000 | £28,000 |
| CGT on gain (24%) | Variable (depends on gain) | Variable |
| Stamp Duty on remortgage | Variable | Variable |
| Legal fees | £2,000–£5,000 | £2,000–£5,000 |
| Total upfront cost | £20,000+ | £40,000+ |
At a saving of £1,600/year on one property, the payback period is 12+ years. That's before accounting for higher company mortgage rates.
Exception: Properties with large mortgages, high rents, and minimal capital gains may have a shorter payback period. Model it specifically rather than using a rule of thumb.
Landlords who need income now
If you're retired or relying on rental income to live, extracting profits from a company adds dividend tax (33.75% at Higher rate, after CT). The net position may be similar to personal ownership, negating the tax saving.
Basic-rate taxpayers
At Scotland's Basic rate (20%) or Intermediate rate (21%), the gap between personal income tax and corporation tax (25%) is small or negative — there's no tax advantage to incorporation. Section 24 penalty at Basic rate is 0% (the credit equals the rate), so that driver also disappears.
Setting up a company for BTL
If you decide to use a company structure for new purchases:
Special Purpose Vehicle (SPV)
Most BTL companies are Special Purpose Vehicles — companies whose sole purpose is holding property. They have their own mortgage products, typically SIC code 68209 (renting and operating of own or leased real estate).
Setting up: Register a company at Companies House (£50 online). Standard articles of association are fine. Appoint yourself as director and shareholder. Open a business bank account.
Mortgages: Use a mortgage broker experienced in limited company BTL. Lenders include: Foundation Home Loans, Precise Mortgages, Paragon Bank, Shawbrook Bank. Not all high-street lenders offer company BTL.
Accountancy: A company requires annual accounts, corporation tax returns, and confirmation statements. Budget £750–£1,500/year for accountancy fees. This is tax-deductible against company profits.
Share structure for couples
If buying jointly as a couple, consider the share structure carefully:
- Equal shares (50/50): dividends split equally, tax based on each spouse's personal rates
- Unequal shares: dividends can be split in any ratio, directing income to the lower-rate spouse
- Different classes of shares: allows flexible dividend allocation
The spouse with the lower marginal tax rate should hold enough shares to use their Basic rate band for dividend extraction. Get advice from an accountant on the optimal structure before registering.

Mortgage considerations for Scottish landlords
Company mortgage rates
Limited company mortgages typically carry a 0.5–1% higher rate than equivalent personal mortgages. On a £150,000 mortgage at 1% extra, that's £1,500/year in additional interest cost — which is itself tax-deductible against company profits. At 25% CT, the after-tax extra cost is £1,125/year.
Compare this to the annual tax saving from CT vs personal rates. On £10,000 rental profit at 42%:
- Personal tax (after Section 24): ~£2,360
- Company tax (CT at 25%, no Section 24): ~£750
- Annual saving: £1,610
- Less extra interest cost after CT: £1,125
- Net annual advantage: £485/year on this scenario
The advantage grows with more properties, higher mortgage balances, and higher rental profits.
Scottish bank notes and company accounts
Company bank accounts are straightforward — all major business banks serve Scottish companies. The registered office can be in Scotland.
Scotland vs England: the ADS difference
The biggest structural difference for Scottish landlords considering incorporation:
| Transfer cost element | Scotland | England |
|---|---|---|
| Property surcharge on transfer | 8% ADS | 3% SDLT surcharge |
| On £200,000 property | £16,000 | £6,000 |
| Extra cost of Scottish transfer | +£10,000 | Baseline |
This makes the payback period for Scottish incorporation significantly longer than for equivalent English landlords. It's one reason why the "incorporate existing portfolio" decision is rarely right in Scotland — and "incorporate new purchases from the start" is the dominant strategy.
Frequently Asked Questions
Do I lose the ADS refund if I buy through a company?
Yes. The ADS refund (for replacing your main residence) only applies to natural persons — individuals, not companies. A company buying property has no "main residence" to replace, so the 8% ADS is a permanent cost.
Can a limited company get a residential mortgage?
Some limited companies can access residential mortgages, but most BTL mortgage products designed for companies are buy-to-let products. You can't typically use a company to buy your own home (in which case you'd pay the main residence rate, not the BTL rate).
What accounting software do I need?
At minimum, you need software that can produce company accounts and a CT600 (corporation tax return) for HMRC. Xero, QuickBooks, or FreeAgent all work — your accountant will likely have a preference.
Is there a small companies' rate of corporation tax?
Yes — companies with profits under £50,000 pay 19% corporation tax (the "small profits rate"). Between £50,000 and £250,000, there's marginal relief. For most small BTL portfolios, the 19–25% rate applies, all of which is below Scotland's Higher rate.
What if I want to wind up the company eventually?
Closing a company holding property triggers CGT on any gains, and LBTT/ADS if you transfer properties out to yourself. Plan your exit strategy before incorporating — sometimes a Members' Voluntary Liquidation is more tax-efficient than selling the company's assets.
