Frequently Asked Questions
Everything you need to know about limited company accounting.
You need to file if you are self-employed, a landlord, a company director, or have untaxed income such as dividends, savings interest, or foreign income. If your income exceeds certain thresholds or you have capital gains, you may also need to register. Our accountants can help determine your obligations.
Our service includes full preparation and filing of your SA100 return, calculation of your tax liability, and identification of allowable expenses and reliefs. We handle all correspondence with HMRC on your behalf and ensure your return is submitted accurately and on time.
First, you provide us with your income and expense details. We then prepare your SA100 return, review it with you, and submit it electronically to HMRC. We also forward the tax bill to you for payment before the deadline, ensuring a smooth process.
You'll need your P60, P45, and any self-employment records, such as income and expenses. Also include records of rental income, dividends, capital gains, and any other income. We'll guide you on what's needed for your specific situation.
We register as your agent with HMRC, which authorises us to act on your behalf. This allows us to file your return and communicate with HMRC. You'll need to provide us with your UTR number and other details to complete the registration.
If your return is late, HMRC charges penalties, and interest on any unpaid tax. To avoid this, our team ensures your return is filed well before the 31st January deadline. We also offer support if you've already missed a deadline, helping you minimise penalties.
We offer transparent fixed-fee packages with no hidden costs. 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 there are no surprises.
