Frequently Asked Questions

Everything you need to know about limited company accounting.

You need to file Self Assessment Tax Returns if you are self-employed, a sole trader, a landlord with rental income, a company director, or if you have other untaxed income such as dividends, savings interest, or foreign income. It's also required if your income exceeds £100,000 or if you need to pay Capital Gains Tax.

Our service includes full preparation and filing of your SA100 return, HMRC agent registration, calculation of your tax liability, identification of allowable expenses and reliefs, and digital submission before the deadline. We also provide ongoing support and advice throughout the year.

You provide us with your income and expense details, and we handle the rest. We'll prepare your SA100 accurately, claim all eligible reliefs, and submit it to HMRC electronically. We'll also advise you on any tax due and ensure you meet the 31st January deadline.

You'll need to provide documents such as P60s, P45s, payslips, bank statements, records of self-employment income and expenses, rental income details, dividend vouchers, and any other relevant financial records. We'll guide you on exactly what's needed.

Once you instruct us, we'll register as your agent with HMRC. This allows us to communicate with HMRC on your behalf, access your tax records, and submit your returns. We handle all the paperwork, so you don't have to worry about the administrative hassle.

If you miss the deadline, HMRC will automatically issue a late-filing penalty, even if you have no tax to pay. If you're worried about missing the deadline, our accountants will ensure your return is filed on time. If you've already missed it, we can help you submit as soon as possible and potentially mitigate 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 sources and the level of support you require. You'll always know the cost upfront before we begin work.
