OK, let me break it down for you.
I do this for a living. I have done it for very very big companies and public sector entities. I have done it for a very long time -- over 30 years.
I have had experience with many different Payroll systems. I know their abilities and weaknesses.
You do not. You don't even work with Payroll systems. You don't even do implementations on a large scale. You work with little tiny implementations by your own statements.
My 30+ years of direct experience across multiple large companies and systems trumps your handful of years in itty bitty systems.
The proposal cannot be implemented quickly.
People can believe your assertions or my contentions.
I note (as should others) you can't even answer my simple question about the most primitive of payroll issues.
Answer my question or admit you have no idea of what you are talking.
There you go again, waving around an unverifiable resume, throwing insults and asking red herring questions. Lots of fallacies, no logic.
Here’s the logic:
The tax code changes annually.
Those tax code changes generally get finalized in the summer, July to September range.
Those tax code changes go into effect Jan 1.
If you can’t get tax code changes into your payroll software in under a year, as you state, then you can’t have payroll software that actually works.
Mid year changes have happened twice in the last 20 years (a withholding change by Bush41 and a full tax change by Bush43 both with about 3 months notice), so even if this change was somehow “bigger” than the normal annual change it’s still a demonstrated FACT that these changes HAVE BEEN (and therefore CAN) be implemented in months not years.
That’s the basic reality, your 1, 2 maybe 5 years claim flies in the face of the annual changes every payroll software has had to deal with since the first one got written. These kind of changes ARE implemented quickly EVERY SINGLE YEAR by EVERY PAYROLL SYSTEM in the nation. Wave your fallacies around all you want but the FACTS show your original statement is BS.
