Holiday scheme in the payroll software is not calculating the annual entitlement correctly when compared to the government website calculator. Also, when you tick on 'override' in order to put in the correct entitlement, all the values change and the remaining holiday balance is then calculated based on the accrual value up to the date you are running the payroll and NOT the annual entitlement that you have HAD to override in order to show the same figures as GOV.UK.
No matter how many days I add or take away, the system will not provide the correct remaining balance. I added more days by how much it was out by i.e. 1 day, 0.5 days, etc. but it would still not give the right remaining balance, it would reduce the remaining balance by more than what I increased it by, i.e. overridden entitlement and increased by 0.5 day but the remaining balance reduced by 1.5 days!
It was also evident that on some employees it was not rounding up but rounding down - this is against government legislation, holiday leave is always rounded up. https://www.gov.uk/holiday-entitlement-rights
Older employees were calculating correctly and most of new/current year starters were incorrect, however, no pattern is present as some new/current starters were calculating correctly. Spent 2 hours on helpdesk with no actual resolution but to try and call HMRC to question their calculations in order to confirm that the entitlement is correct/incorrect and to raise this issue as an idea on the idea portal.
The holiday schemes are not complex and we have been lead to believe it has been set up correctly, however, helpdesk can't recommend anyone on the team to actually guide us through the scheme set-up to ensure everything is in fact correct. It is evident that the system coding needs to be looked at and needs to be amended to follow HMRC holiday leave calculation. https://www.gov.uk/holiday-entitlement-rights
