Frequently Asked Questions
Everything you need to know about limited company accounting.
You need to file if you're self-employed, a sole trader, a landlord with rental income, a company director, or if you have untaxed income from savings, investments, or foreign sources. Even if your income is below the personal allowance, you may still need to register if you receive certain types of income. Our accountants can help you determine your filing obligation.
Our service includes full preparation and filing of your SA100 return, calculation of your tax liability, advice on allowable expenses and reliefs, and submission to HMRC. We also handle all correspondence with HMRC on your behalf. We ensure your return is accurate and compliant, giving you peace of mind.
First, you provide us with your income and expense details. Our qualified accountants then prepare your SA100 return, ensuring all figures are correct and all allowances are claimed. We submit the return electronically to HMRC and provide you with a copy for your records. We also confirm your tax liability and any payment deadlines.
You'll need to provide documents such as P60s, P45s, bank statements, records of self-employment income and expenses, rental income statements, dividend vouchers, and details of any capital gains or foreign income. Our team will guide you on exactly what we need to complete your return accurately.
To act on your behalf, we must be registered as your agent with HMRC. This involves completing a form 64-8 or doing it online through your HMRC account. Once registered, we can correspond with HMRC and file your return for you. We handle this process seamlessly, so you don't have to worry.
If you miss the deadline, you may face late-filing penalties starting at £100, even if you have no tax to pay. Our service ensures you never miss the deadline, as we monitor all key dates and submit your return well in advance. If you've already missed a deadline, we can still help you file and minimise any penalties.
We offer transparent fixed-fee packages with no hidden costs. The exact fee depends on the complexity of your tax affairs, such as the number of income sources. We provide a clear quote before you commit, so you know exactly what to expect. Our pricing is competitive and reflects the expertise of our qualified accountants.
