Understanding Taxation for Buy-to-Let Limited Companies 

A buy-to-let limited company pays Corporation Tax on its rental profits and on gains when it sells property, instead of Income Tax and Capital Gains Tax. Unlike an individual landlord, it can deduct mortgage interest as an expense.

Limited Company or Individual Ownership: Understanding the Differences in Taxation

A limited company is a legal entity in its own right, quite separate from its owners, shareholders or directors.

When owning property in your own name, perhaps as a sole trader, you are personally liable for taxes on this property ownership. For example, income from your property activities is added to your other income and it is taxed as a whole.

A limited company is also a separate entity from a financial and tax point of view, however. This means that the obligation to account for and pay taxes on the business activities of the company falls on the limited company rather than its owners.

What Taxes do Buy-to-Let Limited Companies Pay?

In general terms, buy-to-let limited companies pay the same taxes at the same rates as other limited companies.

Buy-to-let limited companies are more likely to be involved in the buying, selling, letting and ownership of property than limited companies generally, however. This means that limited companies will need to have an understanding of the taxes that apply to buying, selling letting and ownership of property.

Some of the taxes that apply to buy to let limited companies include Stamp Duty, Corporation Tax and Value Added Tax.

Stamp Duty

The higher residential rates are the standard Stamp Duty bands plus a 5% surcharge on each band. They normally apply when a limited company buys residential property, and when an individual buys an additional one.

SDLT applies in England and Northern Ireland. Scotland has Land and Buildings Transaction Tax (LBTT) and Wales has Land Transaction Tax (LTT), which differ.

If you are buying a cheap home in Wales or a budget property in England, you could fall into the lower tax bands and reduce your total stamp duty payable.

The rates of Stamp Duty are different for non-residential, commercial and mixed-use property and Stamp Duty is only applicable when the property costs more than £150,000.

Multiple Dwellings Relief used to reduce the Stamp Duty payable when buying more than one dwelling in a single or linked transaction. It was abolished for transactions completing on or after 1 June 2024, as set out in the government's abolition notice.

Corporation Tax

Buy-to-let limited companies pay Corporation Tax on their profits. They do not pay Income Tax or National Insurance Contributions on their income.

What is Corporation Tax?

Corporation Tax is levied on UK limited companies and some other organisations including housing associations, clubs and societies. It is based on the annual taxable profits that a company generates.

Limited companies need to register for Corporation Tax when they start doing business. They must then file their Company Tax Return (CT600) within 12 months after the end of their accounting period. This will indicate how much Corporation Tax is payable. Any Corporation Tax payable is due by the relevant deadline which in most cases is 9 months and 1 day after the end of their accounting period.

What is Corporation Tax Charged On?

Corporation Tax is levied on limited company profits after salaries and other allowable business expenses have been deducted but before dividends to shareholders are paid.

Taxable profits for Corporation Tax purposes include the money a company makes from doing business (known as its trading profits), investments, and from selling assets for more than they cost (known as chargeable gains). Assets include machinery, land and property.

What are the Rates of Corporation Tax?

Since April 2023, the main rate of Corporation Tax has been 25%, on taxable profits above £250,000. Profits of £50,000 or less may qualify for the 19% small profits rate, while companies with profits between the limits may qualify for marginal relief. The £50,000 and £250,000 limits are reduced for short accounting periods and according to the total number of associated companies. See the current Corporation Tax rates and allowances and HMRC's marginal relief guidance.

Unlike Income Tax, Corporation Tax does not have a tax-free allowance. It is levied on the total amount of trading profits.

Corporation Tax for Buy-to-Let Companies

A significant factor for buy-to-let limited companies is that while tax legislation now restricts the mortgage interest individuals can claim against tax these restrictions do not apply to limited companies. Limited companies can still claim the interest they pay on buy-to-let mortgages as an allowable expense against income.

A company can deduct qualifying finance costs when calculating its property-business profits, whereas the rules for individual residential landlords restrict Income Tax relief for finance costs. That difference does not make company ownership automatically more tax efficient: the result also depends on the company's Corporation Tax rate, the cost of extracting profits, financing, acquisition and disposal taxes, and the investor's intended exit.

Capital Gains Tax

Buy-to-let limited companies are not liable to pay Capital Gains Tax (CGT) on their capital gains when assets are disposed of as individuals are. However, it is useful to understand how this difference affects taxation for limited companies.

Capital Gains Tax is a tax which is charged on any gain made when you dispose of (or sell) chargeable assets less certain allowances. Chargeable assets include personal possessions worth more than £6,000 (except cars), stocks and shares, business assets and investment property.

A company pays Corporation Tax on its chargeable gain when it disposes of property. That tax is not simply the 19% small profits rate. The company's actual Corporation Tax rate depends on its profits, accounting period and associated companies. Taking sale proceeds out of the company can also create a separate personal tax charge. Compare the complete acquisition, ownership, disposal and extraction position rather than one headline rate.

Value Added Tax

A business generally has to register for Value Added Tax when its VAT-taxable turnover exceeds the current £90,000 threshold. Exempt and out-of-scope supplies do not count towards taxable turnover.

VAT registered limited companies must charge VAT on goods and services they provide at the appropriate rate. They may reclaim the VAT they pay on purchases.

Residential property letting is normally exempt from VAT, so VAT is not normally charged on residential rents. VAT directly attributable to exempt letting cannot generally be reclaimed, although the position can depend on the company's other activities and partial-exemption rules.

With commercial buildings, landlords may exercise what is known as an option to tax. VAT is then charged on the rent and VAT on allowable expenses may be reclaimed.

Holiday accommodation is standard-rated for VAT. Its income therefore counts towards VAT-taxable turnover even though ordinary residential rent is normally exempt.

Other Taxes

Other taxes buy-to-let limited companies might have to pay, include Business Rates and Council Tax on property they own, except where it is occupied by a tenant who pays these taxes.

Taxation for Buy-to-Let Company Directors and Shareholders

Money taken out of a buy-to-let limited company can create a personal tax bill for its owners, separate from the company's own Corporation Tax. Owners, directors and shareholders can take money out as a salary, dividends, director's loans or pension contributions, or leave it in the company. They can choose how and when they take it, so the method and timing can be planned around their own tax position.

When a buy-to-let property is owned by an individual instead, the rental profit or loss from it is added to their other income. Any allowances they are entitled to are then deducted. The result sets both their tax rate and the Income Tax they pay.

Limited companies who are employers are, as with all employers, liable to pay Employers' National Insurance Contributions.

Special Purpose Vehicles and Holding Companies

A special purpose vehicle, or SPV, is a limited company set up for one specific purpose, such as owning buy-to-let property.

It is possible to own buy-to-let property through a trading limited company which has other business activities as well as property. There can be disadvantages to this, however. It means it is difficult to separate the buy-to-let from the company's other activities, which is why an SPV is often considered instead.

Consideration should be given to whether an SPV should own several buy-to-lets, or whether each should be owned by a separate SPV. A holding company can own several related SPVs as its subsidiaries. The way ownership is structured and therefore in which buy-to-let income, profits and losses are accrued will have important implications for tax purposes.
