Frequently Asked Questions
Everything you need to know about limited company accounting.
You need to file a Self Assessment Tax Return if you are self-employed, a sole trader, or have untaxed income such as rental income, dividends, or foreign income. If you earn over £1,000 from self-employment or have other untaxed income, you must register with HMRC. Our team can help you determine if you need to file.
Our service includes full preparation and filing of your SA100 return, calculation of your tax liability, and identification of all allowable expenses and reliefs. We also handle all HMRC correspondence on your behalf and provide year-round support. We ensure your return is submitted correctly and on time.
Once you engage us, we'll send you a simple checklist of documents and information we need. You provide your income details, expenses, and any other relevant information. We then prepare your SA100 return, review it with you, and submit it to HMRC digitally. We handle everything, making the process effortless for you.
You'll need to provide documents such as P60s, P45s, bank statements, records of self-employment income and expenses, rental income statements, dividend vouchers, and any other relevant financial documents. We'll provide a detailed checklist to ensure we have everything needed to complete your return accurately.
To act on your behalf, we need to be registered as your agent with HMRC. This is a straightforward process where we link your tax records to our account. Once registered, we can handle all communications with HMRC, including filing your return and responding to any queries.
If your Self Assessment is late, HMRC may charge penalties. The late filing penalty starts at £100, even if you have no tax to pay. Additional penalties apply if you delay further. To avoid this, we ensure your return is filed well before the 31st January deadline, so you never face late filing 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 streams or property portfolios. We'll provide a clear quote upfront, so you know exactly what you'll pay before we start.
