• Self-employment income: If you are self-employed and earn income from running your own business, you will need to include this income on your self-assessment tax return.
• Employment income: If you are employed and earn income from a job, this income will typically be subject to PAYE tax and National Insurance contributions deducted at source. However, you may still need to include this income on your self-assessment tax return if you have additional income that is not subject to PAYE.

• Rental income: If you receive rental income from a property you own, this income will need to be included on your self-assessment tax return.
• Investment income: If you receive income from investments, such as dividends or interest, this income will need to be included on your self-assessment tax return.
• Foreign income: If you receive income from overseas, this income will need to be included on your self-assessment tax return.
• Capital gains: If you sell an asset, such as a property or shares, and make a profit, this may be subject to Capital Gains Tax, and the gain will need to be included on your self-assessment tax return.

It’s important to note that there may be other types of income or gains that are required to be included on a self-assessment tax return depending on individual circumstances. If you’re unsure about whether you need to include a particular type of income or gain on your tax return, it’s always best to seek advice from an accountant or tax adviser.
