HMRC Online Self Assessment

Self Assessment is a system used by HMRC for collecting income tax in the United Kingdom. The tax amount payable is more often than not subtracted automatically from the wage amount. Individuals and businesses with other income have to report it in a self assessment tax return. It is not just the self-employed who need to be bothered about self assessment tax returns. Rather, a self assessment tax return needs to be submitted if:

  • an individual gets £2,500 or more as untaxed income e.g. income from property rental or save instruments
  • an individual’s savings or investment income is £10,000 or more before tax
  • an individual made profits from selling shares, or a home and is required to pay Capital Gains Tax
  • an individual is a nominated business partner
  • an individual has income from abroad and is required to pay tax on foreign income
  • an individual who lives abroad and has a UK income
  • an individual received dividends from shares
  • an individual receives a P800 from HMRC stating that enough tax wasn’t paid the previous year

Individuals who are self employed must keep few things such as business records and transaction details up-to-date and in order so that it is easy for computation and to update documents when the time comes. Individuals also need to be up-to-date on Payments on Account for each year which also includes paying advance tax i.e. for 6 months on 31st January and 31st July for each financial year. DNS Accountants can help self employed plan their savings better and make sure that no additional tax is paid.

How to Pay your Self Assessment Tax Bill in Tax Return Deadlines

For any new business, a self employed individual must register with the HMRC, in advance, before they start trading. Key self assessment deadlines include:

  • 31st January – By 31st January, the self employed must file their online tax returns for the prior year and pay the tax amount due, if any. In addition to this, self employed need to make the first “payment on account” for the following year

  • 5th April – The tax year ends on 5th April. Post this date, the HMRC will get in touch with self employed for their Self Assessment tax return

  • 31st July – Important for “payments on account”

  • 31st October – For submitting paper tax returns, 31st October is the deadline

Any deadline missed, will impose penalties. The HMRC expected all owner-managed-businesses to file their tax returns on time and provide accurate details of the earnings.

As mentioned earlier, businesses might need to register for Value added tax separately. Self employed can read more about self assessment tax returns and tax codes on our DNS Accountants website.
