If revenue and customs can't count

Ok, so maybe this is a rant, and maybe it is due to the fact I forgot my annual Pay As You Earn (PAYE) employers return and was fined £400...

But seriously...

This is the government!
This is the part of the government that calculates how much our taxes are!!
This is intelligent automated software that they've had designed that should be 200% idiot proof.

I've had no employees for the past 12 months and I'm trying to submit (basically) an empty / null return.

Apparently I have employees on the list for whom I have not completed a P14 - note the list displays no employees, there's another summary page later on that tells me I'm submitting for 0 employees, so they know !!!!
