Self Assessment Tax Return Services

Make sure you have the following information on hand to streamline the self assessment process: your Unique Taxpayer Reference (UTR), Government Gateway ID, activation code (for your first UK self assessment), National Insurance number, invoices or payment receipts, income from other jobs (e.g., P60, dividend income, etc.), your salary details, etc. 

You can claim various allowable expenses, including office costs (e.g., stationery and phone bills), travel costs (e.g., fuel, parking, or public transport fares), clothing expenses (e.g., uniforms), staff costs (e.g., salaries and subcontractor expenses), and items purchased for resale (e.g., stock or raw materials). 

It is important to register for self assessment with HMRC by the 5th of October following the tax year in which your income or gains initially occurred to avoid potential penalties. Even if you have reported a property disposal within 60 days, you might still need to complete a separate registration for self assessment.
