Whether you will have to pay taxes on your leave pay will depend on the specific type of leave you are taking and the laws in your country. For example, if you are taking a leave under the Family and Medical Leave Act (FMLA) in the US, the pay you receive during your leave may be tax-free. However, if you are taking a personal leave of absence without pay, you will not receive any pay and therefore will not have to pay taxes on it.
