Tax Returns

Self Assessment allows you to report your income and capital gains to HM Revenue & Customs (HMRC) and claim any allowances or tax reliefs you are entitled to.

Depending on your circumstances, your return may need supplementary pages covering self-employment, property income, employment, foreign income or capital gains.

At C Warmington & Son, we prepare and submit your tax return, calculate your tax liability and explain when payments are due. We review your information carefully to help you claim the appropriate expenses, allowances and reliefs.

Missing filing or payment deadlines can result in penalties, while late tax payments may also attract interest. Preparing early helps you meet your obligations and budget for any tax due.

For help with your tax return, call us on 01865 777755.

Self Assessment Tax Returns

Who needs to complete a tax return?

If your income is taxed through PAYE, you will not usually need to complete a Self Assessment tax return unless other circumstances apply.

You may need to submit a return if you:

  • Are self-employed with gross trading income exceeding £1,000 in a tax year.

  • Are a partner in a business partnership.

  • Receive rental income, foreign income or other untaxed income.

  • Receive dividends or investment income that needs to be reported.

  • Have Capital Gains Tax to pay.

  • Need to pay the High Income Child Benefit Charge and do not pay it through PAYE.

Company directors may also need to submit a return, depending on their income and personal circumstances.
