Frequently Asked Questions
Everything you need to know about limited company accounting.
You need to file a Self Assessment Tax Return in Co Antrim if you are self-employed, a sole trader, a landlord with rental income, or if you have untaxed income such as dividends, foreign income, or capital gains. Additionally, if you earned over £1,000 from self-employment or have a high income that requires you to pay the High Income Child Benefit Charge, you must register for Self Assessment. Our accountants can help you determine if you need to file and ensure you meet all HMRC requirements.
Our Self Assessment Tax Returns service in Co Antrim includes full preparation and filing of your SA100 form, calculation of your tax liability, identification of allowable expenses and reliefs, and digital submission to HMRC. We also handle all communication with HMRC on your behalf, including responding to any queries or notices. We ensure your return is accurate and submitted before the 31st January deadline, giving you complete peace of mind.
The process starts with you providing us with all your income and expense details for the tax year. Our accountants will then review this information, complete the relevant sections of the SA100, and calculate your tax liability. We will send you a summary for approval before we submit the return electronically to HMRC. Throughout the process, we keep you informed and are available to answer any questions you may have.
You will need to provide documents such as your P60 or P45 from employment, bank statements, records of any self-employment income and expenses, rental income statements, dividend vouchers, and details of any other income or gains. If you have foreign income, you may also need to supply relevant tax documents from abroad. Our team will guide you on exactly what we need to ensure a smooth filing process.
To act as your agent, we need to be registered with HMRC. This involves linking your tax account to our agent account using your Unique Taxpayer Reference (UTR) and other verification details. Once registered, we can correspond with HMRC on your behalf, file your return, and deal with any queries. We handle this process for you, making it seamless and hassle-free.
If you miss the deadline, you may face late-filing penalties, which increase over time. At SATR, we proactively monitor all deadlines and ensure your return is submitted well in advance. If you have already missed a deadline, we can help you file as soon as possible and advise on how to handle any penalties you may have incurred.
We offer transparent fixed-fee packages with no hidden costs, so you know exactly what you'll pay upfront. The exact fee depends on the complexity of your tax affairs, such as the number of income sources and the level of record-keeping required. We'll provide a clear quote before we begin, ensuring there are no surprises. Our pricing is competitive and reflects the expert service you receive.
