Follow these steps to input trading and property income on a CT600 form:

1. Enter the figure for Profit/(loss) on ordinary activities before taxation – this is the total of trading profit/(loss) and property profit/(loss).
2. Enter Disallowable expenditure (Depreciation).
3. Go to Tax adjusted profit/(loss) worksheet – other adjustments > Income from UK land and buildings.
4. Select Yes for Do you wish to use this wizard to calculate the income?
5. Enter Income from UK land and buildings – this is the rent received, before expenses.
6. Enter Property income related expenses – this is the total expenses included in the profit/(loss) figure in Step 1.
7. Enter Other capital allowances – this is any additional expenses not included in calculating the profit/(loss) figure.

Worked example

This example shows you how to complete a CT600 form using the following trading and property income figures:

• Trading loss = £15,000
• Disallowable expenditure (depreciation) = £250
• Taxable trading loss = £15,000 - £250 = £14,750
• Rent received = £5,000
• Rental expenses = £2,500
• Capital allowances/other expenses = £1,000
• Taxable property income = £2,500 - £1,000 = £1,500

Calculate and enter the following figures (see diagram):

• Profit/(loss) on ordinary activities before taxation = £(15,000) + £5,000 - £2,500 = £(12,500)
• Disallowable expenditure (Depreciation) = £250

Go to Tax adjusted profit/(loss) worksheet – other adjustments > Income from UK land and buildings and enter the following figures (see diagram):

• Income from UK land and buildings = £5,000
• Property income related expenses = £2,500
• Other capital allowances = £1,000

Note: If you enter Income from UK land and buildings net of expenses (that is, as £5,000 - £2,500 = £2,500), then you don’t need to enter Property income related expenses.
