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 if you have untaxed income from savings, investments, or foreign sources. High earners, company directors, and CIS contractors also typically need to register for Self Assessment. SATR can help you determine your filing requirements and ensure you stay compliant with HMRC.

Our service includes complete preparation and filing of your SA100 return, calculation of your tax liability, and identification of all allowable expenses and reliefs. We also handle all HMRC correspondence as your agent, and provide year-round support for any tax-related queries. With SATR, you get a comprehensive, end-to-end solution for your Self Assessment needs.

Once you provide your income and expense details, our accountants review them and prepare your SA100 accurately. We then submit your return digitally to HMRC, well before the 31st January deadline. We also calculate your tax liability and advise you on payment deadlines. The entire process is handled by us, so you just need to provide the necessary information.

You'll 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 taxable income. Our team will guide you on exactly what's needed to ensure your return is accurate and complete.

When you engage SATR, we become your authorised agent with HMRC. This means we can act on your behalf, correspond with HMRC, and manage your tax affairs directly. We handle the registration process for you, ensuring all authorisations are in place so we can file your return and deal with any queries.

If you miss the 31st January deadline, you may face late-filing penalties from HMRC. SATR ensures this never happens by monitoring all deadlines and submitting your return well in advance. If you've already missed a deadline, we can help you file as soon as possible and minimise any penalties.

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 streams you have. We provide a clear quote upfront, so you know exactly what you'll pay before we start. Our goal is to make professional tax help accessible and affordable.
