Self Assessment Tax Returns in Marlow Made Simple

You typically need to file if you are self-employed, a sole trader, or have untaxed income such as rental income, dividends, or foreign income. If you earn over £1,000 from self-employment or have a tax liability not covered by PAYE, you must register for Self Assessment. Our accountants can help determine your requirements.

Our service includes full preparation and filing of your SA100 return, calculation of your tax liability, and identification of all allowable expenses and reliefs. We handle all correspondence with HMRC on your behalf and ensure your return is submitted digitally before the deadline. We provide a complete, stress-free solution.

You provide us with your income and expense details, and we do the rest. We prepare your SA100 return, calculate your tax and National Insurance contributions, and submit it electronically to HMRC. We also advise on any payments due and ensure all deadlines are met.

You'll need your Unique Taxpayer Reference (UTR), National Insurance number, details of all income sources (P60s, P45s, dividend vouchers, rental statements), and records of any allowable expenses. We'll guide you on exactly what to provide to ensure a smooth filing.

Once you engage us, we'll register as your agent with HMRC. This authorises us to act on your behalf, including submitting your Self Assessment Tax Return and handling any communications. We'll manage the entire process, so you don't have to deal with HMRC directly.

If you miss the deadline, HMRC will issue a late-filing penalty, which increases over time. Our proactive approach ensures you never miss a deadline. If you're already late, we can still help you file immediately and minimise any penalties by acting quickly.

We offer transparent fixed-fee packages with no hidden costs. The exact price depends on the complexity of your tax affairs, but you'll always know the fee upfront. We provide a one-off package that covers everything, so you can budget with confidence.
