Ask the company to convert the allowance to basic salary. There are a few reasons why you want to do that:
- increment and bonus are calculated based on basic salary.
- when you change job next time, the future employer may consider only the basic salary for your salary increment, for example, 20% increment on top of the basic salary. Each company has different compensation package with regard to allowance and other benefits.
