Need your self-assessment taken care of?

At SBX, we understand that self-assessment as a sole trader can be a challenge. You’re managing your books and facing HMRC requirements, which can feel daunting. We’re here to ease that burden with a reliable service to handle your annual tax return, ensuring your trade profits, losses, and personal income are accurately reported for compliance.

Support Tailored to You

For those with straightforward income – such as freelancing or a small retail business – our flat-fee return preparation offers a practical solution. We’ll review your records, calculate your taxable income, and submit your Self-Assessment, keeping costs manageable and the process straightforward.

Handling Complex Finances

If your situation involves complications like rental income or investments, we step in with ICAEW-standard accounts. This includes detailed profit and loss statements and a focus on identifying tax savings, such as allowable expenses or reliefs, to optimise your finances.

Looking Ahead

We also assess your overall financial picture to determine if switching to a limited company could improve your take-home pay. We’ll consider tax rates, setup costs, and long-term benefits, guiding you through the process if it suits your goals, including registration with Companies House.
