Frequently Asked Questions
Everything you need to know about limited company accounting.
You typically need to file a Self Assessment Tax Return if you are self-employed, a sole trader, or a landlord with rental income. Additionally, individuals earning over £100,000, those with untaxed income like capital gains, or people with foreign income may also need to register. If you're unsure, our accountants can help you determine your obligations.
Our service includes full preparation and submission of your SA100 form, calculation of your tax liability, and identification of all allowable expenses and reliefs. We also handle HMRC correspondence on your behalf, ensuring you stay compliant without the stress. We provide end-to-end support, so you don't have to worry about any aspect of the process.
First, you provide us with your financial details and any relevant documents. We then prepare your SA100, double-checking every figure for accuracy. After you review and approve, we submit it to HMRC digitally, well before the deadline. We keep you informed throughout, so you always know where your return stands.
You'll need to provide proof of income, such as P60s, P45s, or self-employment records, along with details of any rental income, dividends, or capital gains. Also, keep records of allowable expenses, like business costs or professional fees. Our checklist will guide you, and we can help you organise your paperwork.
Once you authorise us as your agent, we can act on your behalf with HMRC. This means we can correspond with them, access your tax records, and submit your return electronically. We handle the registration process for you, making it seamless and stress-free.
If you miss the deadline, you may face late-filing penalties, which increase over time. However, with SATR, we ensure your return is submitted well in advance, so you never have to worry about penalties. If you've already missed a deadline, we can help you file as soon as possible and minimise any consequences.
We offer transparent, fixed-fee packages, so you know exactly what you'll pay upfront with no hidden costs. The fee depends on the complexity of your tax situation, but we'll provide a clear quote before you commit. Our aim is to provide affordable, professional support without any surprises.
