Frequently Asked Questions

Everything you need to know about limited company accounting.

You typically need to file if you are self-employed, a sole trader, a landlord with rental income, or have untaxed income from investments or foreign sources. If you earn over £1,000 from self-employment, you must register for Self Assessment. Our accountants can help you determine if you need to file.

Our service includes full preparation and submission of your SA100 return, calculation of your tax liability, and identification of all allowable expenses and reliefs. We also act as your HMRC agent, handle all correspondence, and ensure your return is filed before the deadline.

First, you provide us with your income details, expenses, and any relevant documents. We then prepare your SA100 return, ensuring everything is accurate and compliant. After your approval, we submit it electronically to HMRC, and you'll receive a confirmation of submission.

You'll need your Unique Taxpayer Reference (UTR), National Insurance number, P60 or P45 forms, records of any self-employment income and expenses, bank statements, and details of any other income such as rental or dividends. Our checklist ensures you have everything covered.

Once you authorise us as your agent, we register with HMRC on your behalf. This allows us to handle your Self Assessment correspondence, submit returns, and manage your tax affairs directly with HMRC. It's a straightforward process that we manage for you.

If you've missed the deadline, it's crucial to act quickly to minimise penalties. We can still file your late return and help you communicate with HMRC to reduce any fines. Our team will guide you through the process and ensure you become compliant as soon as possible.

We offer transparent fixed-fee packages with no hidden costs. The fee depends on the complexity of your tax situation, such as the number of income sources. You'll receive a clear quote upfront, so you know exactly what to expect.
