Frequently Asked Questions
Everything you need to know about limited company accounting.
You need to file if you are self-employed, a sole trader, a landlord with rental income, or earn over £1,000 from a side hustle. You also need to file if your income from savings or investments is over £10,000, or if you have foreign income. Our accountants can confirm your filing requirement and ensure you meet HMRC rules.
Our service includes full SA100 preparation and submission, HMRC agent registration, income calculation across all sources, and claiming all allowable expenses and reliefs. We also provide proactive tax planning and deadline reminders. Everything is handled digitally, and we keep you informed throughout the process.
First, you provide your financial details and documentation securely via our online portal. We then calculate your tax liability, complete the SA100, and submit it to HMRC on your behalf. We also handle any follow-up queries from HMRC, and you receive a copy of your return for your records.
You'll need your P60 or P45 from employment, records of any self-employment income and expenses, rental income statements, dividend vouchers, and bank interest certificates. If you have foreign income, we'll need relevant tax documents. We'll provide a tailored checklist to ensure you have everything.
We register with HMRC as your authorised agent, which allows us to act on your behalf when dealing with your tax affairs. This means we can contact HMRC, respond to notices, and manage your Self Assessment Tax Returns without your direct involvement. It saves you time and ensures professional handling of your tax matters.
If you miss the deadline, HMRC will issue a late-filing penalty, which increases the longer you delay. However, with our service, we ensure your return is submitted well before the deadline, so you never face penalties. If you've already missed a deadline, we can help you file as soon as possible and minimise any fines.
We offer transparent fixed-fee packages with no hidden costs, tailored to your individual circumstances. The exact fee depends on the complexity of your return, such as the number of income sources. You'll receive a clear quote upfront, so you know exactly what to expect. Contact us for a personalised quote.
Absolutely. Our accountants are experts in identifying legitimate reliefs and allowances, including the personal allowance, marriage allowance, and capital allowances. We thoroughly review your finances to ensure you claim every deduction you're eligible for, reducing your tax bill legally and maximising your savings.
