Tax Periods are set by the HMRC. Tax Period months always run from the 6th of one month to the 5th of the next month. The 1st tax month runs from 6th April to 5th May. The 2nd tax month runs from 6th May to 5th June and so on. Similarly Tax Period weeks are periods of seven days starting from 6th April.
52-53 Tax-Year. A special type of tax year is the 52-53 week tax year. This is a tax year which ends on the same day of the week within a month instead of the last day of that month (for instance, the last Friday in March instead of March 31). This results in some tax years being 52 weeks long and some being 53 weeks long.
