Frequently Asked Questions

Everything you need to know about limited company accounting.

You typically need to file a Self Assessment tax return if you are self-employed, a sole trader, a landlord with rental income, or have untaxed income from savings, investments, or foreign sources. Even if you're employed, you may need to file if your income exceeds £100,000 or you have additional income to declare. Our accountants can help determine your obligations.

Our service covers the complete preparation and filing of your SA100 tax return, including calculating your tax liability, identifying allowable expenses, and submitting to HMRC digitally. We also provide year-round advice and support, ensuring you meet all deadlines and stay compliant with HMRC.

You provide us with your income and expense details, and we handle the rest. We'll prepare your SA100, calculate your tax, and submit it to HMRC online. You'll receive a copy of your return and a clear breakdown of any tax owed. We also liaise with HMRC on your behalf if any questions arise.

You'll need to provide documents such as P60s, P45s, bank statements, records of self-employment income and expenses, rental income statements, and any other relevant financial paperwork. Our checklist ensures you don't miss anything, making the process smooth and efficient.

Once you engage our services, we'll register as your agent with HMRC. This allows us to communicate with HMRC on your behalf, submit your tax return, and handle any enquiries. We manage the entire process, so you don't have to worry about the administrative side.

If you miss the deadline, you'll face automatic late-filing penalties from HMRC. However, with SATR, we ensure your return is submitted well before the deadline, so you never have to worry about penalties. We proactively track all deadlines and remind you of upcoming filings.

We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your tax return, such as the number of income streams and whether you have capital gains. We'll provide a clear quote upfront, so you know exactly what to expect.
