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 if you have untaxed income from savings, investments, or foreign sources. Additionally, company directors and high earners with income over a certain threshold may need to file. If you're unsure, our accountants can help you determine your obligations.
Our service includes full preparation and filing of your SA100 return, calculation of your tax liability, and maximisation of allowable expenses and reliefs. We also register as your HMRC agent, handle all correspondence with HMRC, and provide year-round tax planning advice. You receive a dedicated accountant who ensures your return is accurate and compliant.
First, you provide us with your income details, expenses, and any relevant documents. We then prepare your SA100 return, ensuring all figures are correct and all allowances are claimed. After your approval, we submit the return electronically to HMRC and confirm the filing. We also calculate your tax liability and advise on payment deadlines.
You'll need to provide your UTR number, P60 or P45 forms, details of any self-employment income and expenses, rental income records, bank interest statements, and records of any other income such as dividends or foreign income. Our checklist ensures you gather everything required for a smooth filing.
We register as your agent with HMRC, which gives us authorisation to act on your behalf for tax matters. This allows us to correspond with HMRC, file your returns, and manage any queries. We handle all the paperwork, so you don't have to worry about the administrative burden.
If you miss the 31st January deadline, you may face late-filing penalties and interest on any tax owed. Our team ensures your return is filed well before the deadline, eliminating this risk. If you've already missed a deadline, we can help you file as soon as possible and advise on penalty mitigation.
We offer transparent, fixed-fee pricing with no hidden costs. The exact fee depends on the complexity of your return, such as the number of income streams or properties. You'll receive a clear quote upfront, so you know exactly what to expect. We aim to provide exceptional value for the peace of mind we offer.
