Employer asking for latest payslip? Why?

HR asking for latest payslip, should I give it?

In my previous company the JO is around 12k but I lied and told the employer that my previous pay was 15k and allowance (to avoid being low-balled). Now that the employer called me that I am qualified for the position, they asked for my latest payslip.

For short, buking ako if ibigay ko yung annual salary ko because of BIR 2316. So I was thinking na i-reason that the pay out would be like (Basic salary 12k + Allowance 3k + incentives).

For those who experienced this. What is the best approach for this? Possible ba na ireason ko 'yung payout na na-mention ko above as my reason bakit mababa ang payslip ko?

Please help! I really need a good paying job 🥺
