Individual reviewing a Self Assessment tax return with I Sumar & Co

Self Assessment - Done Properly, Filed On Time

Personal tax return services for individuals, sole traders, landlords and company directors across the UK. We make sure you claim every relief you are entitled to - and never miss a deadline.

A Self Assessment tax return is one of those jobs that hangs over you until it is done - and getting it wrong, or late, means penalties and interest. Whether your tax affairs are simple or genuinely complex, we take the whole thing off your hands. I Sumar & Co prepare and file personal tax returns for clients across the UK, making sure every figure is right, every allowable relief is claimed, and the return is submitted well before the deadline. As specialist accountants, we also make sure you are not paying a penny more tax than you have to.

Do You Need to File a Tax Return?

You may need to complete a Self Assessment return if you are:

  • self-employed or a sole trader

  • a landlord receiving rental income

  • a company director

  • a higher earner, or affected by the High Income Child Benefit Charge

  • receiving significant income from savings, investments or dividends

  • earning income from abroad, or living abroad with UK income

  • selling assets and liable for capital gains tax

Not sure if you need to file? We will tell you - and handle it if you do. The current filing requirements are published at gov.uk.

What Our Personal Tax Service Includes

Every employer has legal duties to enrol eligible staff into a workplace pension and contribute to it. The rules are strict and the penalties for getting them wrong are real. We manage auto-enrolment from start to finish - assessing your workforce, setting up the scheme, handling contributions and keeping you compliant as your team changes. Current contribution rates and duties are published at gov.uk.

Self Assessment - Frequently Asked Questions

  • The online filing and payment deadline falls at the end of January following the tax year, with the tax year ending in early April. We file well ahead of the deadline so you have time to plan for what you owe. The exact dates are published at gov.uk.

  • HMRC charges an automatic penalty for missing the deadline, with further penalties and interest the longer it remains outstanding. The simplest way to avoid all of it is to let us handle the return in good time.

  • That depends on your circumstances, but it often includes far more than people realise. Part of our job is identifying every allowable expense and relief you are entitled to, so you do not overpay.
