Frequently Asked Questions

Everything you need to know about limited company accounting.

You need to file a Self Assessment Tax Return if you are self-employed, a sole trader, a landlord with rental income, or if you have untaxed income from savings, dividends, or foreign sources. Additionally, if your income exceeds £100,000 or you need to claim certain reliefs, you may be required to file. Our accountants can help you determine your obligations and ensure you meet HMRC's requirements.

Our service includes a comprehensive review of your income and expenses, preparation of your SA100 return, accurate calculation of your tax liability, and digital submission to HMRC. We also handle all correspondence with HMRC on your behalf and provide proactive tax planning advice to minimise your tax bill. We ensure your return is fully compliant and submitted well before the deadline.

Once you engage us, we'll ask you to provide your financial details, such as income statements, expense records, and any relevant tax documents. Our accountants will then prepare your SA100 return, ensuring every figure is accurate and every allowable expense is claimed. After your review and approval, we submit the return electronically to HMRC and provide you with a copy for your records.

You'll need to provide evidence of all your income, such as P60s, P45s, bank statements, dividend vouchers, and rental income records. You should also include records of any allowable expenses, such as receipts for business costs, professional fees, and home office expenses. If you have foreign income, you'll need relevant documents from overseas. Our team will guide you on what's required.

To act on your behalf, we must be registered as your agent with HMRC. This involves adding our agent details to your HMRC account, which authorises us to correspond with HMRC and manage your tax affairs. We handle this process for you, ensuring you remain in control while we deal with the administrative burden.

If you've missed the 31st January deadline, it's crucial to act quickly to minimise penalties. We can still file your return late, but you may face penalties from HMRC. Our accountants will assess your situation and advise on the best course of action, including helping you file as soon as possible and potentially negotiating a reduction in penalties if you have a reasonable excuse.

We offer transparent fixed-fee packages with no hidden costs, tailored to the complexity of your tax affairs. This means you know exactly what you'll pay upfront, with no surprises. Our pricing is competitive and reflects the level of service you receive, including expert advice and support throughout the year. Contact us for a personalised quote.
