for CS, how many months of your past salary do they ask for when crafting the offer? the standard 3 months?

reason i'm asking is that I recently got promoted (3 months ago) and I hope they take that into consideration. Also my bonus is also there in the last three months, so will they take my annual compensation into consideration or only monthly?

recently jo teo said employers cant ask candidates to showpast payslip. Any difference since then?
