Tax permissable or not

slms,

Is it permissible for a person to put their child on the payroll to save paying more tax.
Pls kindly advise.

Wasalam

May Allah bless you.
If its done with the correct legal parameters and there is no lies involved then yes, it is permissible.
If you have to lie to do it or are in breach of the legal requirement then no, it is not permissible.

And Allah knows best!
