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 landlord, a company director, or have untaxed income such as dividends, interest, or foreign income. Additionally, if your income exceeds £100,000 or you need to pay the High Income Child Benefit Charge, you must file. SATR can help you determine your obligation and ensure you comply with HMRC rules.

Our service includes a full review of your financial records, preparation of your SA100 form, calculation of your tax liability, and digital submission to HMRC.

We handle all communication with HMRC on your behalf, giving you complete peace of mind.

Simply provide us with your income and expense details, and we'll do the rest. Our accountants will prepare your SA100, calculate your tax liability, and submit it electronically to HMRC before the deadline. We'll also advise you on any tax due and help you set up a payment plan if needed. You'll receive a copy of your return for your records.

Typically, you'll need your P60 or P45 if you're employed, bank statements showing interest, dividend vouchers, records of any rental income or self-employment income, and receipts for allowable expenses. If you're claiming certain reliefs, such as marriage allowance, we may need additional documentation. We'll provide a comprehensive checklist to make gathering everything straightforward.

After you engage us, we'll register as your agent with HMRC by completing the necessary authorisation forms. This allows us to communicate with HMRC on your behalf, submit your return, and deal with any queries. The process is simple and ensures that all correspondence goes through us, saving you time and hassle.

If you miss the deadline, you'll face automatic late-filing penalties. However, if you file with SATR, we'll never let that happen. We set reminders well in advance and submit your return early, ensuring you avoid any penalties. If you've already missed the deadline, we can still help you file as soon as possible to minimise the impact.

Our pricing is transparent and tailored to your specific tax situation. We offer a fixed fee for standard Self Assessment Tax Returns, with no hidden costs. For more complex cases, such as those involving multiple income streams or foreign income, we provide a bespoke quote after an initial consultation. This ensures you know exactly what you'll pay before we start.

Absolutely. Our accountants provide proactive tax planning advice throughout the year, not just at filing time.
