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, savings interest, or foreign income. Even if you are employed, you may need to file if your income exceeds certain thresholds or you receive benefits in kind. If you're unsure, our accountants can help you determine your obligations.

Our service includes full preparation and submission of your SA100 return, calculation of your tax liability, and identification of all allowable expenses and reliefs. We also handle all HMRC correspondence and provide year-round advice on tax planning. Our fixed-fee packages are transparent, with no hidden costs.

First, you'll need to register for Self Assessment and obtain a Unique Taxpayer Reference (UTR) if you haven't already. You'll then gather your income and expense records, which we'll use to complete your SA100 return. We'll review everything with you, calculate your tax, and submit electronically to HMRC before the deadline.

You'll need to provide your UTR, National Insurance number, and details of all income, including employment, self-employment, rental, dividends, and foreign income. You should also provide records of any allowable expenses, such as business costs, professional fees, and charitable donations. We'll guide you on exactly what's needed.

Once you engage our services, you'll need to authorise us as your agent with HMRC. This involves linking your UTR and National Insurance number to our firm. We'll guide you through the simple online process, and once authorised, we can handle all communications and submissions on your behalf.

If you miss the deadline, HMRC will issue a late-filing penalty, which increases the longer you delay. To avoid this, our team ensures your return is submitted well before the deadline. We also offer support if you've already missed a deadline, helping you get back on track as quickly as possible.

We offer transparent fixed-fee packages for our Self Assessment Tax Returns service, so you know exactly what you'll pay from the start. The fee depends on the complexity of your tax affairs, but we never charge hidden costs. We'll provide a clear quote before you commit, so there are no surprises.

Absolutely. Our accountants are experienced in dealing with foreign income and can help you comply with HMRC's requirements. We'll ensure you declare all relevant income and claim any applicable foreign tax credit relief, minimising your UK tax liability while staying fully compliant.
