What % to come under 40% tax

[Pensiongrey]

Can anyone help me???
I earn 65k a year- I want to salary sacrifice to come under the 40% tax bracket.

what % of my wage do I need to sacrifice?

If you sacrifice cash where would you want it to go (eg into a pension)?

You need to sacrifice £15k so it’s around 23%, that will take you to £50050.

23% approx, to get to £50,050 taxable income.

I use this website: Tax Calculator | UK Tax Calculators I increase my pension contribution to stay under 40% tax.

Thanks so much - yes sacrifice into a pension.
My form at work requires a % amount and so
just wanted to double check.

Appreciate the replies
