Personal and commercial tax – Important deadlines

Running your own business can be an empowering and fulfilling alternative to financially restricting traditional employment. But not everything in life is perfect, and the unavoidable grey lining to the entrepreneurial silver cloud is dealing with complex tax matters – with many pressing deadlines.

So let’s make it simple – here are the upcoming dates you’ll need to take note of for the financial year of April 2017 to April 2018.

Self-Assessment

31 July 2017 – deadline for your second Self-Assessment payment on account for tax year ended 5 April 2017.
31 October 2017 (midnight) – deadline for paper Self-Assessment return for tax year ended 5 April 2017.
31 January 2018 – deadline for the online completion of your Self-Assessment return for tax year ended 5 April 2017.

VAT
VAT payments are made every quarter, however the exact deadline will depend on when you originally registered for VAT, which in turn would have been based on when your accounting periods begin and end.

Corporation Tax
Where your profits are under £1.5 million, the corporation tax deadline will typically be 9 months and 1 day following the end of your accounting period. This deadline will be in place following your first year trading, as your first deadline may be slightly before this. HMRC will contact you to notify you as to when your corporation tax is due.

The end of the accounting period for corporation tax is typically the month end on the anniversary of incorporation.

Where you’ve made over £1.5 million in profit, your corporation tax will be paid in instalments as follows:

  • 6 months and 13 days after the first day of your accounting period
  • 3 months after your first instalment
  • 3 months after your second instalment
  • 3 months and 14 days after the last day of your accounting period
