Self Assessment Tax Return
made simple

To file your self assessment tax return, you'll need your National Insurance number and Unique Taxpayer Reference (UTR). Also, you’ll need to gather information on your income sources like self-employment earnings, property rental income, and any untaxed income.

For allowable expenses, consider including costs such as office supplies, expenses related to your home office, and professional fees.
