Frequently Asked Questions
Everything you need to know about limited company accounting.
If you are self-employed, a sole trader, a landlord with rental income, or you have untaxed income from savings, investments, or foreign sources, you likely need to file a Self Assessment Tax Return. Additionally, if you earn over £100,000 or need to pay the High Income Child Benefit Charge, you must also file. Our accountants can confirm your obligation and help you register with HMRC if needed.
Our service includes a comprehensive review of your income and expenses, preparation of your SA100 form, calculation of your tax liability, and submission to HMRC. We also act as your agent, handle all HMRC correspondence, and provide year-round advice on tax planning. You receive a dedicated accountant who ensures your return is accurate and compliant.
The process begins with you providing your financial details and supporting documents. We then prepare your SA100, ensuring all income and allowable expenses are correctly reported. After your review and approval, we submit the return electronically to HMRC. We also calculate any tax due and advise on payment deadlines to avoid penalties.
You'll need to provide your UTR number, details of all income sources (such as P60s, P45s, dividend vouchers, rental income statements), and records of any allowable expenses. If you're self-employed, a simple summary of your business income and expenses is often sufficient. Our accountants will guide you on exactly what's needed.
Once you engage us, we'll apply to HMRC to become your authorised agent. This involves adding us to your Self Assessment account. After approval, we can communicate with HMRC on your behalf, view your tax records, and submit returns. This ensures seamless handling of your tax affairs.
If you've missed the 31st January deadline, it's crucial to act quickly. We can still file your return, but you may incur late-filing penalties. Our accountants will assess your situation and help you minimise any penalties by submitting as soon as possible. We also advise on paying any tax due to reduce interest charges.
We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your tax affairs, but we always provide a clear quote upfront. Whether you have simple employment income or multiple rental properties, our pricing is competitive and tailored to your needs.
Yes, we are fully prepared for Making Tax Digital for Income Tax. Our accountants can help you transition to digital record-keeping and ensure your Self Assessment Tax Returns are submitted using compatible software. We'll keep you compliant with all current and future HMRC requirements.
