Frequently Asked Questions

Everything you need to know about limited company accounting.

You typically 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 such as dividends, savings interest, or foreign income. Additionally, if you earn over £100,000 or need to pay the High Income Child Benefit Charge, you must also register for Self Assessment. Our team can help you determine if you need to file.

Our service includes a full review of your income and expenses, preparation of your SA100 tax return, submission to HMRC, and calculation of your tax liability. We also act as your HMRC agent, dealing with any correspondence and ensuring you claim all allowable expenses and reliefs. We provide a comprehensive, stress-free service from start to finish.

First, you provide us with your financial details and any relevant documents. Our accountants then prepare your SA100, ensuring every figure is accurate and that you claim all legitimate deductions. We submit the return to HMRC electronically and send you a confirmation. You'll have peace of mind knowing your return is filed correctly and on time.

HMRC agent registration allows us to act on your behalf with HMRC, giving us the authority to handle your tax affairs. This means we can correspond with HMRC, submit your return, and resolve any queries without your involvement. It's a straightforward process and ensures your Self Assessment Tax Returns are managed efficiently.

If you miss the deadline, HMRC will automatically issue a late-filing penalty, which starts at £100 even if you have no tax to pay. Further penalties apply if you're more than three months late. To avoid this, it's essential to file on time. Our team ensures your return is submitted well ahead of the deadline, so you never face penalties.

We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your tax affairs, such as the number of income sources. We'll provide a clear quote before you commit, so you know exactly what you'll pay. This transparent approach ensures there are no surprises.
