Frequently Asked Questions

Everything you need to know about limited company accounting.

You need to file if you are self-employed, a sole trader, a landlord with rental income, a company director, or if you have untaxed income such as foreign income or capital gains. If you earn over £1,000 from self-employment or have other taxable income not taxed at source, HMRC requires you to register for Self Assessment and submit an SA100 each year.

Our service includes registering you as our client with HMRC, preparing your SA100 accurately, calculating your tax liability, identifying allowable expenses and reliefs, and submitting your return electronically before the deadline. We also provide ongoing support and advice throughout the year, ensuring you remain compliant and tax-efficient.

First, you provide us with your income details and expenses. Our accountants review the information, apply all relevant allowances and deductions, and complete the SA100 form. We then submit it to HMRC online and provide you with a copy of your tax calculation. We handle all correspondence with HMRC until your return is accepted.

You'll need to provide documents such as your P60 or P45 from employment, records of any self-employment income and expenses, details of rental income, dividend vouchers, bank interest statements, and any other income sources. If you have capital gains, you'll need records of the assets sold. Our team will guide you on exactly what's required.

Once you instruct us, we'll register as your agent with HMRC. This allows us to communicate with HMRC on your behalf, submit your SA100, and manage any queries. You'll need to authorise us online or by post, and we'll handle the rest. This ensures a smooth and efficient process.

If you miss the deadline, HMRC will issue a late-filing penalty, which increases over time. To avoid this, we always submit your return well before the deadline. If you've already missed it, we can still file your return and help you minimise penalties by responding to HMRC promptly and explaining any reasonable excuse.

We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your tax affairs, such as the number of income sources and whether you have capital gains or foreign income. You'll receive a clear quote upfront, so you know exactly what you'll pay before we start.
