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, a company director, or you have untaxed income such as dividends or foreign income. If you earn over £1,000 from self-employment or have other untaxed income, you must register for Self Assessment and file an SA100 return.
Our service includes registering you as a client with HMRC, preparing and submitting your SA100 form, calculating your tax liability, and identifying allowable expenses and reliefs. We also handle all correspondence with HMRC on your behalf and provide proactive deadline reminders to ensure you never miss the 31st January filing deadline.
Once you provide us with your income and expense details, our accountants will review the information, calculate your tax liability, and complete the SA100 form. We then submit it electronically to HMRC via our agent account, well before the deadline. You'll receive a copy of your return and a breakdown of your tax position for your records.
You'll need to provide documents such as P60s, P45s, self-employment records, rental income statements, dividend vouchers, bank interest statements, and details of any other taxable income. It's also helpful to have records of allowable expenses, such as business mileage, office costs, and professional fees. We'll guide you on exactly what we need.
When you engage our services, we register as your agent with HMRC. This allows us to act on your behalf, submit your Self Assessment Tax Return, and handle any correspondence with HMRC. You'll need to authorise us through your HMRC online account, and we'll guide you through the simple process.
If you miss the 31st January deadline, you may incur a late-filing penalty starting at £100, even if you have no tax to pay. Our proactive deadline monitoring ensures you never miss this date. If you've already missed it, we can still file your return quickly to minimise penalties, but we strongly advise acting promptly.
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 or whether you have capital gains. You'll receive a clear quote upfront, so you know exactly what to expect before you commit.
