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, or have untaxed income such as rental income, dividends, or foreign income. If you earned over u00a31,000 from self-employment or have a complex tax situation, you'll likely need to register and file. Our accountants can help you determine your obligations.

Our service includes full SA100 preparation, accurate calculation of your tax liability, maximisation of allowable expenses and reliefs, and digital submission to HMRC. We also handle all correspondence with HMRC on your behalf as your appointed agent, ensuring a smooth and compliant process.

First, you'll provide us with your income and expense details. Our accountants then prepare your SA100, calculating your tax and any payments due. We'll send you a summary for approval before submitting it to HMRC electronically. You'll receive a copy of your filed return for your records.

You'll need to provide any documents showing your income, such as P60s, P45s, bank statements, and records of self-employment income. You should also include receipts for allowable expenses, details of any rental or dividend income, and information about pension contributions or charitable donations.

To act on your behalf, we must be registered as your agent with HMRC. We handle this registration process for you, which authorises us to deal with your tax affairs. This allows us to correspond with HMRC, file your return, and manage any queries that arise.

If you miss the deadline, you'll incur an automatic u00a3100 penalty, with further fines if you delay longer. To avoid this, we proactively monitor key dates and ensure your return is submitted well in advance. If you've already missed a deadline, we can help you file as soon as possible to mitigate additional penalties.

We offer transparent fixed-fee packages with no hidden costs. Your fee will depend on the complexity of your tax affairs, such as the number of income sources you have. We'll provide a clear quote upfront, so you know exactly what to expect before you commit.
