Frequently Asked Questions

Everything you need to know about limited company accounting.

You need to file if you are self-employed, a landlord, a company director, or have income from savings, investments, or foreign sources. If you earn over £1,000 from self-employment or have other untaxed income, you must register for Self Assessment. We can help you determine your filing obligations.

Our service covers everything from registering you with HMRC as an agent to preparing and submitting your SA100 form. We calculate your tax liability, identify allowable expenses and reliefs, and ensure you meet the 31st January deadline. We also handle all correspondence with HMRC on your behalf.

First, you provide us with your income and expense details. Our accountants then prepare your SA100, including all relevant schedules. We review everything for accuracy and completeness, then submit it electronically to HMRC. You'll receive a copy of your return and a breakdown of your tax liability.

You'll need to provide your UTR number, P60 or P45 if employed, bank statements, records of any self-employment income and expenses, rental income statements, and details of any capital gains or dividends. We'll guide you on exactly what's needed.

We are registered with HMRC as authorised agents, which allows us to act on your behalf. Once you authorise us, we can communicate with HMRC, file your return, and manage any queries. This means you don't have to deal with HMRC directly.

If your return is filed after the 31st January deadline, HMRC charges a late-filing penalty. We proactively ensure your return is submitted on time, so you never face these penalties. If you've already missed a deadline, we can help you submit immediately and potentially mitigate penalties.

We offer transparent fixed-fee packages with no hidden costs. The fee depends on the complexity of your tax affairs, such as the number of income streams you have. We'll provide a clear quote upfront so you know exactly what you'll pay.
