Which country? This makes no sense. The UK payslip is entirely for the purpose of displaying before tax, deductions, and post-tax salary. It's a PAYE receipt, effectively.
Nordic countries do this. They call it an "employment fee", which is calculated on your salary and does not show up on your pay slip. It is quite sustainable as well. Of course you also have your "normal" income tax, which is withheld from you before payment and shows up on your pay slip. Also quite sustainable.
