There are, basically, two ways to deduct pension at source by an employer.
-
employee nominates amount for pension, that is taken from their pay on pay day, their take home is reduced. It's taken before tax. Therefore, for a basic rate tax payer putting in £100 costs them £80. Employer pays, say, £60 and they pay no NI on that element so it doesn't cost them £60 as such.
Employee contribution is £100, employer contribution is £60.
This is what the majority of schemes do.
It's a payroll deduction, but it's not salary sacrifice using the HMRC rules.
-
salary sacrifice. Your salary is £50k. You want to pay £2k pa into your pension. You enter into a different contractual arrangement with your employer whereby your employer reduces your salary to £48k, and you get a letter explaining that. It is a contractual change.
Then, the employer makes a £2k pa contribution to your pension scheme. And adds their own contribution of £200.
£2,200 is ALL an employer contribution . There is NO employee contribution.
As a result of this, both parties now save the NI. The employer saves it on the full contribution instead of just their bit, and the employee saves it on what is just an employer contribution, increasing their take home pay by the NI element of the £2k. Both parties are better off.
I'm definitely not wrong. I have introduced these schemes to employers.
I can appreciate that people use the term incorrectly though.
Where you say "all relevant taxes", you're simply using irrelevant words. It's tax. Tax is saved. Unless you use sal sac, then NI is saved as well.
But there are a lot of other rules around sal sac and the admin burden for the employer is a lot higher.
So, what RR is suggesting, is limiting the NI saving in my 2) to the first £2k pa. Which, to be quite honest, won't impact that many people.
But I suspect the reason she is considering it is because more employers are thinking that the admin burden of sal sac is more worth it with the recent NI increase.
All this information is available on the internet. Especially the HMRC website.
And there are plenty of other posts on this thread that have explained it. So maybe read all that before making a tit of yourself.
