The UK corporation tax rate reduced from 20% to 19% (effective 1 April 2017) and will be further reduced to 17% (effective from 1 April 2020) following changes substantively enacted on 6 September 2016. This will reduce the Company's future current tax charge accordingly. The deferred tax asset at 29 March 2019 has been calculated based on the rate of 17% substantively enacted at the balance sheet date.

The effective tax rate of 17.8% (2018: 18.5%) is lower than the UK corporation tax rate principally due to the non-deductibility of depreciation charged on capital expenditure, non-deductible amortisation of intangible assets and adjustment in respect of prior periods.

The tax charge for the period was £9.1m (2018: £12.4m), including a £1.4m credit (2018: £0.8m credit) in respect of tax on non-underlying items.

An income tax credit of £nil (2018: £0.2m 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 £172m (2018: £168m) with the main taxes including corporation tax of £12.7m (2018: £16.1m), net VAT of £72.2m (2018: £67.2m), employment taxes of £48.2m (2018: £47.3m) and business rates of £39.8m (2018: £37.5m).
