Frequently Asked Questions
Everything you need to know about limited company accounting.
You need to file if you're self-employed, a sole trader, a landlord with rental income, or have untaxed income such as dividends, interest, or foreign earnings. Also, if your income exceeds £100,000 or you have capital gains, you may need to register. If you're unsure, our accountants can help determine your obligation.
Our service includes HMRC agent registration, preparation and filing of your SA100, calculation of your tax liability, and identification of allowable expenses and reliefs. We also provide proactive tax planning and year-round support to ensure you stay compliant and minimise your tax bill.
You provide your income and expense details, and we handle the rest. We complete the SA100 accurately, claim all applicable reliefs, and submit it digitally to HMRC before the deadline. You'll receive a copy of your return and a breakdown of your tax liability, so you know exactly what you owe.
You'll need your UTR number, P60 or P45 if employed, bank statements, receipts for expenses, records of any rental income, dividend vouchers, and details of any capital gains. If you have foreign income, provide relevant documents. We'll guide you on exactly what's needed.
To act on your behalf, we register with HMRC as your agent. Once registered, we can correspond with HMRC, submit your return, and handle any queries. This ensures all communications go through us, saving you time and stress.
If you miss the 31st January deadline, HMRC charges a late-filing penalty. With SATR, we proactively monitor deadlines and ensure your return is submitted on time, so you never face penalties. If you've already missed a deadline, we can help you file as soon as possible to minimise any additional charges.
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. You'll receive a clear quote upfront, so you know exactly what you'll pay. We believe in fair, competitive pricing for professional service.
