I strongly advise against outrightly lying like that.

It's ok to BS a bit about your job scope, leadership skills, appraisal, size of project etc, but to directly lie about actual verifiable numbers is taking a big risk.

Like you correctly point out HR will ask for your payslip and bonus letters, you will then be forced into a corner and either have to admit you were BS-ing earlier or cover the first lie with a 2nd bigger lie.

Coming out with a tall tale like you were actually paid allowances, bonuses or some dubious cash items "off the record" or some huge promotion is coming "soon" is a big red flag for any seasoned hirers. You won't be the first one that try this stunt and unlikely you will find someone dumb enough to believe that.

Most big MNCs have to submit their offers to C&B dept for approval and quoting off the market wages & bonuses will sometimes trigger internal audit.
