Frequently Asked Questions
Everything you need to know about limited company accounting.
You typically need to file if you're self-employed, a sole trader, a landlord with rental income, or have untaxed income such as dividends, savings interest, or foreign income. If you earn over £1,000 from self-employment or have a high income, you'll likely need to register. Our accountants can help you determine your filing requirement.
Our service includes HMRC agent registration, preparation and submission of your SA100 return, calculation of your tax liability, and identification of all allowable expenses and reliefs. We also handle all HMRC correspondence and provide year-round support, ensuring your return is accurate and compliant.
First, you'll provide us with your income and expense details. We'll then prepare your SA100 return, calculate your tax, and submit it digitally to HMRC. We'll also advise you on any tax due and payment deadlines, so you're never caught off guard.
You'll need your UTR number, P60 or P45 forms, records of any self-employment income and expenses, rental income statements, dividend vouchers, and details of any other untaxed income. We'll provide a comprehensive checklist to ensure we have everything needed for a complete return.
We'll register as your agent with HMRC, which allows us to act on your behalf. This means we can handle all correspondence, submit your return, and manage any queries from HMRC. You'll need to authorise us, and we'll guide you through the simple process.
If you've missed the deadline, it's crucial to file as soon as possible to minimise penalties. Our accountants can still prepare and submit your return, and we'll advise you on the penalties you may face. We'll help you get back on track quickly and avoid further issues.
We offer transparent fixed-fee packages with no hidden costs. The fee depends on the complexity of your return, such as whether you have rental income or capital gains. We'll provide a clear quote upfront so you know exactly what to expect.
