Frequently Asked Questions
Everything you need to know about limited company accounting.
You may need to file a Self Assessment Tax Return if you are self-employed, a landlord, a company director, or have untaxed income such as dividends or foreign income. Even if you're employed, you might need to file if your income exceeds a certain threshold or you have capital gains. Our accountants can help you determine if you need to file and guide you through the process.
Our service includes full preparation and submission of your SA100 return, calculation of your tax liability, and advice on allowable expenses and reliefs. We also handle all HMRC correspondence and ensure your return is filed before the deadline. We provide a comprehensive, end-to-end service so you don't have to worry about any aspect of your tax return.
You provide us with all your income and expense records, and we take it from there. We'll prepare your SA100 return accurately, ensuring every figure is correct and that you claim all the deductions you're entitled to. We then submit it digitally to HMRC and send you a copy for your records. The process is straightforward and completely handled by our team.
You'll need to provide documents related to your income, such as P60s, P45s, dividend vouchers, and records of any self-employment or rental income. You should also keep receipts for any allowable expenses you wish to claim. Our checklist will guide you through exactly what we need, and we're happy to advise if you're unsure.
Once you instruct us, we'll register as your agent with HMRC, which allows us to deal with them on your behalf. This means we can submit your return, respond to queries, and manage your tax affairs without you having to contact HMRC directly. We handle the entire process seamlessly.
If you've missed the 31st January deadline, don't panic – we can still help you file late and minimise any penalties. We'll submit your return as soon as possible and advise you on the best course of action. Our team is experienced in dealing with late filings and will work to resolve the issue quickly.
We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your tax affairs, and we'll provide a clear quote before you commit. You'll know exactly what you're paying from the start, with no surprises.
