Tax returns for the self-employed

We provide professional Self Assessment and tax-rebate services for individuals working in the construction industry under CIS, sole traders, and anyone declaring income from a variety of activities. Our fixed-fee pricing means no surprises — and as an officially registered HM Revenue & Customs agent, you can rely on us to file your return correctly and within the shortest possible timeframe.

Our specialists keep their qualifications continuously up to date with the latest HMRC rules and reliefs, so every claim we submit on your behalf reflects the current allowances available to you.

When is a Self Assessment return required?

You are typically required to submit an annual tax return to HMRC if any of the following apply:

• You worked under the Construction Industry Scheme (CIS).
• You were self-employed as a sole trader.
• You worked as self-employed within a partnership.
• You served as a director of a limited company.
• You received income from dividends or rental property.
• You hold significant savings or investment income.
• You sold or gifted property, land or other taxable assets.
• You received income from outside the United Kingdom.

How the process works

We have refined the declaration process into a transparent, staged workflow. It begins as soon as you provide the initial information and authorise our agent to represent you with HMRC. Once authorised, we prepare your return, share the draft for your review, and answer every question before anything is submitted.

Our work doesn't end at filing. You can come back to us at any point during the year for follow-up questions, post-submission queries, or HMRC correspondence — your assigned accountant remains available throughout.
