Oh no - more RTI PAYE questions

[Eric Mc]

I actually don't think so. The power to charge interest on late monthly payments of PAYE and NI was given to HMRC as far back as 2008.

They obviously could do little about this until something like RTI was introduced so they have now set this system in place, 18 months after RTI was started (6 April 2013)

Funny this thread should come back up - I have another question for the experts: I'm just getting round to doing last months wages (normally pay on last day of the month, but been too busy last few days). So if I do it today and enter today's date, then at the end of October I enter this months wages for 31st, two months worth of wages fall into October. Will we end up with extra NI being deducted because of this (our employee's pay period is monthly)?

If so, I'd be better to enter it as 31st September, and suffer a late submission.

Don't use 31 September - there is no such date

RTI expects that the submissions be sent to HMRC ON THE PAYROLL DATE. If you submit them after the set payroll date, they will be deemed as being late and will be liable to a penalty.
However, as the latest HMRC update states, penalties will not be actually levied for small employers until April 2015.
So all you will get for the moment is a Generic Employer's Notice warning you that you were late and that a penalty would have been charged in normal circumstances.
