Property company accounts and CT600

With SimpleCompanyTax, file your property company’s CT600 and eligible micro-entity accounts. Enter UK rental income, property expenses and the tax adjustments that apply to your company.

What figures does a property company need for its CT600?

A property company needs both its prepared rental figures and its company accounts figures. Rental income and property expenses describe the activity during the period. Property assets, borrowing and other balances describe the company at the period end. Keeping those two sets of figures separate makes the return easier to review.

Eligible micro-entity limited companies with UK property income, including companies that both trade and let property.

From rental figures to the property result

This illustration starts with figures the company has already prepared and classified. It explains the arithmetic, not whether a particular expense qualifies for tax relief.

This is not the final Corporation Tax bill. Adjustments, losses and the company’s other income can affect the taxable result.

UK property income, expenses and losses

Property-only or trading and property?

A company that only lets UK property can use the property-only route without inventing trading turnover. A company that also trades needs both sets of prepared figures.

Keep each activity’s figures identifiable. If a question asks how a claim is allocated between activities, use your prepared treatment. Do not put rental income into trading turnover merely to fill a field.

Checks that make the property preview useful

Check that the rental figures cover the return you are preparing and that brought-forward balances belong to the company. Where several property companies share owners, each company still needs its own figures.

A property company may also need associated-company information. The property route does not replace those details, and a portfolio of separately incorporated companies is not one combined return.
