Frequently Asked Questions

Everything you need to know about limited company accounting.

If you are self-employed, a sole trader, a landlord with rental income, or have untaxed income from savings, investments, or foreign sources, you likely need to file a Self Assessment Tax Return. Additionally, if you earn over u00a3100,000 or need to claim certain reliefs, you may also be required to file. SATR can help you determine your obligations.

Our service includes a full review of your income and expenses, preparation of your SA100 return, calculation of your tax liability, and submission to HMRC. We also advise on allowable deductions and ensure you claim all entitled reliefs. We handle all correspondence with HMRC on your behalf.

First, you provide us with your financial details, such as income statements, expense records, and any relevant tax documents. Our accountants then prepare your return, ensuring accuracy and compliance. We submit it to HMRC digitally and provide you with a copy for your records.

You'll need to provide details of all your income, including P60s, P45s, dividend vouchers, bank interest statements, and records of any self-employment or rental income. You should also include receipts for expenses you wish to claim. Our team will guide you on exactly what is needed.

SATR is registered as an agent with HMRC, which allows us to act on your behalf. This means we can correspond with HMRC, submit your return, and manage any queries. We'll handle everything, so you don't have to deal with HMRC directly.

Late filing of Self Assessment Tax Returns results in automatic penalties from HMRC, starting at u00a3100 even if you owe no tax. SATR ensures your return is filed well before the 31st January deadline, so you never face late-filing penalties. We monitor all deadlines for you.

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'll know exactly what you're paying before we start.
