The tax rate was due to reduce from 19% to 17% from 1 April 2020, following changes substantively enacted on 6 September 2016. In the March 2019 Budget it was announced that the corporation tax rate would remain at 19% from 1 April 2020. This was substantively enacted on 17 March 2020.

The deferred tax asset at 3 April 2020 has been calculated based on the rate of 19% substantively enacted at the balance sheet date.

The effective tax rate of 9.7% (2019: 17.8%) is lower than the UK corporation tax rate principally due to the impact of overseas tax rates, adjustments in respect of prior periods now closed with HM Revenue and Customs, and the impact of the rate change in deferred tax recognised in the balance sheet.

The tax charge for the period was £1.9m (2019: £9.1m), including a £5.0m credit (2019: £1.4m credit) in respect of tax on non-underlying items.

An income tax charge of £0.7m (2019: nil credit) on other comprehensive income relates to the movement in fair valuing forward currency contracts outstanding at the year end. No other items within other comprehensive income have a tax impact.

The Group engages openly and proactively with tax authorities both in the UK and internationally, where it trades and sources products, and is considered low risk by HM Revenue & Customs ("HMRC"). The Company is fully committed to complying with all of its tax payment and reporting obligations.

In this period, the Group's contribution from both taxes paid and collected exceeded £208m (2019: £172m) with the main taxes including corporation tax of £16.3m (2019: £12.7m), net VAT of £101.4m (2019: £72.2m), employment taxes of £54.3m (2019: £48.2m) and business rates of £36.3m (2019: £39.8m).
