Other useful information

Taxation of dividends

You do not pay any tax on any dividend income that falls within your Personal Allowance.

You also get a dividend allowance each tax year. You only pay tax on dividend income above the dividend allowance (£500 for 2024-25).

Capital gains

You only pay CGT on overall gains in excess of your annual exempt amount (£3,000 for 2024-25 onwards).

If you disposed of a residential property that was not your main residence, in most cases a capital gains tax return needs to be submitted to HMRC within 60 days of completion, together with CGT payment.

Tax relief for landlords

The old 10% wear & tear allowance was abolished in 2016. Landlords can now claim Replacement Relief.

From April 2020, relief for mortgage interest and other finance costs on residential property is restricted to the basic rate of income tax (20%). This means all finance costs will no longer be an allowable expense when calculating taxable rental profits. An adjustment is required, which gives a basic rate tax deduction after rental profits have been taxed.

Marriage Allowance

Allows you to transfer £1,260 of your Personal Allowance to your spouse/ civil partner (if they earn more than you). This reduces their tax by up to £252.

To benefit as a couple, the lower earner must have income below the Personal Allowance, and the other must be a basic rate taxpayer.

Other tax-free allowances

You can get up to £1,000 tax-free allowances per tax year for property/ trading income.

If you have both types of income, you will get a £1,000 allowance for each. This can be claimed instead of actual expenditure if more beneficial.
