Employers must request proof of transfer, e.g., BIR Form 1905, if applicable, before the employee’s start date. Concerning the withholding taxes, your employer will still remit your taxes to the RDO where you are currently registered. However, please note that out-of-district payments of taxes are still considered as “non-payment” in the event of a tax audit, although the risk of getting audited as an employee is shallow.
