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 with rental income, or have untaxed income from savings, investments, or foreign sources. You may also need to file if your income exceeds £100,000 or you have capital gains to report. Our team can help you determine if you need to register.
Our service includes registering you with HMRC as your agent, preparing and filing your SA100 return, calculating your tax liability, and maximising your allowable expenses and reliefs. We also handle all HMRC correspondence and provide year-round tax planning advice to help you minimise your tax bill.
The SA100 filing process involves gathering all your income and expense records, completing the relevant sections of the form, and submitting it to HMRC. We handle this entirely for you, ensuring accuracy and compliance. We'll guide you on what documents we need and keep you informed throughout the process.
Typically, you'll need to provide your P60 or P45 forms if you're employed, records of any self-employment income and expenses, details of rental income, bank interest statements, dividend vouchers, and any other relevant income or relief documents. We'll provide a tailored checklist to ensure we have everything needed.
HMRC agent registration allows us to act on your behalf for tax matters. We complete an authorisation form that you sign, and HMRC then links our account to yours. This enables us to file your return, respond to HMRC queries, and manage your tax affairs seamlessly. We handle the entire process for you.
If your return is late, HMRC imposes automatic penalties, which increase over time. We ensure your return is filed well before the 31st January deadline to avoid these penalties. If you have missed a deadline in the past, we can help you regularise your affairs and minimise any additional charges.
We offer transparent fixed-fee packages with no hidden costs, so you know exactly what you're paying upfront. The fee depends on the complexity of your tax affairs, but we always provide a clear quote before we begin. Our pricing is competitive and ensures you receive professional, value-for-money service.
