Frequently Asked Questions

Everything you need to know about limited company accounting.

You need to file if you are self-employed, a sole trader, a landlord with rental income, a company director, or if you have untaxed income such as capital gains or foreign income. It's also required if your income exceeds £100,000 or you need to pay the High Income Child Benefit Charge. Our accountants can help you determine if you need to register for Self Assessment.

Our service includes registering you as a client with HMRC, preparing and submitting your SA100 return, calculating your tax liability, and identifying all allowable expenses and reliefs. We also provide ongoing support and advice, ensuring you remain compliant with HMRC regulations. We handle everything from start to finish, so you don't have to worry about a thing.

Once you engage our services, we'll send you a checklist of required information and documents. You provide us with your income details and expense records, and we take care of the rest. We prepare your SA100, review it for accuracy, and submit it electronically to HMRC well before the deadline. We'll also inform you of any tax due and the payment deadline.

You'll need to provide your Unique Taxpayer Reference (UTR), National Insurance number, and details of all your income, such as P60s, P45s, bank interest statements, dividend vouchers, and records of any rental or self-employment income. You should also include records of any expenses you wish to claim. Our team will guide you through exactly what we need.

To act on your behalf, we need to be registered as your agent with HMRC. This involves completing a 64-8 form, which you'll sign, authorising us to handle your tax affairs. Once registered, we can correspond with HMRC on your behalf, submit your returns, and manage any queries. This ensures a seamless and efficient process.

If you've missed the deadline, don't panic. Our accountants can still file your return, but you may incur late-filing penalties and interest on any tax owed. We'll help you submit your return as soon as possible and advise you on how to handle any penalties. We can also set up a payment plan with HMRC if needed, to ease the financial burden.

We offer transparent fixed-fee packages with no hidden costs, so you know exactly what you'll pay upfront. The fee depends on the complexity of your return, such as the number of income sources and the level of detail involved. We'll provide a clear quote before you commit, ensuring there are no surprises.
