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, a landlord with rental income, or have income from other sources such as dividends, foreign income, or capital gains above certain thresholds. Even if you are employed and pay tax through PAYE, you may still need to file if you have additional untaxed income.

Our service includes full preparation and filing of your SA100, calculation of your tax liability, identification of allowable expenses and reliefs, and submission to HMRC. We also handle all correspondence with HMRC on your behalf, ensuring you stay compliant and stress-free.

First, you provide us with your income and expense details, which can be done securely online. Our qualified accountants then prepare your SA100, calculate your tax, and submit it to HMRC digitally. We keep you informed throughout the process and confirm once your return is filed.

You will need to provide documents such as P60s, P45s, bank statements, records of any self-employment income and expenses, rental income statements, dividend vouchers, and details of any other income or capital gains. Our team can guide you on exactly what is required.

With your permission, we register as your agent with HMRC. This allows us to act on your behalf, access your tax records, and handle all communications and submissions. It simplifies the process and ensures that HMRC contacts us instead of you.

If you miss the 31st January deadline, you may incur late-filing penalties. At SATR, we proactively monitor all deadlines and ensure your return is submitted on time. If you have already missed a deadline, we can help you file as quickly as possible and advise on penalty mitigation.

We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your tax affairs, but we always provide a clear quote upfront. You can be confident that our pricing is competitive and represents excellent value for the expertise you receive.
