Social Security returns are done quarterly. Tax returns are done monthly. No matter what way you look at it, it involves extra work for the employer.
There is an extra admin burden. I don't dispute that. The process isn't fundamentally different though, unlike GST, so it doesnt involve a radical overhaul of what you are currently doing. It would be nice if Social and Income Tax could pull the process parallel though.
Somewhere along the line Employers have taken on a workload that was formerly dealt with by someone in the tax dept. Who in the tax dept has been made redundant as a result of this work being,"Out-sourced"?
They haven't - this work didn't exist before.
Previously returns were filed annually, payment was generally made in one lump sum.
Everyone still files a return, which has to be reviewed in exactly the same way as before ITIS. Now they have to issue ITIS rate notices regularly too. Their work burden has increased as a result.
Only difference is that cash comes in via the employer monthly, rather than from the individual in one go. That monthly payment process is the additional work burden, on both sides.
