As a result of the Chancellor’s September 10p tax amendment
your IRIS GP Payroll software needs to be updated.
Why is there a September update this year?
The Chancellor of the Exchequer has introduced changes to help
people on low-income affected by the abolition of the 10% starting
rate of income tax.
What are the changes exactly?
The Chancellor announced that the personal allowance for the
2008-09 tax year will be increased by £600 from £5,435 to £6,035,
and the threshold at which someone starts to pay higher rate tax
will be reduced by £1200 from £36,000 to £34,800.
When do the changes apply?
The new tax code and tax band come into effect on the 7th
September 2008. Therefore you must you make this change prior to
processing your September payroll (Month 6).
Important Note: Do not make the
change until your August payroll has been processed (month
5).
