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 sole trader, a landlord, a company director, or if you have untaxed income such as dividends or foreign income. Even if you're employed but earn over £1,000 from a side business, you may need to register for Self Assessment. Our accountants can help you determine your filing requirement.

Our service includes full preparation and submission of your SA100 form, calculation of your tax liability, identification of allowable expenses and reliefs, and proactive tax planning. We also handle all HMRC correspondence and ensure you meet the 31st January deadline. We provide a comprehensive, stress-free service tailored to your needs.

Once you provide your financial information, we review it for completeness and accuracy. We then prepare your SA100, calculating your tax liability and claiming all relevant allowances. After your approval, we submit the return digitally to HMRC. You'll receive a copy of the submitted return and confirmation from HMRC.

You'll need to provide your Unique Taxpayer Reference (UTR), National Insurance number, P60 or P45 if employed, records of any self-employment income and expenses, details of rental income, dividend vouchers, and any other relevant financial documents. Our checklist ensures you don't miss anything.

To act on your behalf, we register as your agent with HMRC. This involves linking your UTR to our practice via HMRC's online services. Once registered, we can handle all correspondence and submissions for you. This process is straightforward, and we manage it entirely for you.

If you miss the deadline, HMRC will issue a late-filing penalty, and interest will accrue on any unpaid tax. Our proactive service ensures you never miss this date, as we submit your return well in advance. If you've already missed the deadline, we can help you file as soon as possible to minimise penalties.

We offer transparent, fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your return, such as the number of income sources. We'll provide a clear quote before you commit, so you know exactly what to expect. This ensures there are no surprises.
