Change employer but I haven't completed my tax

I started working in Malaysia on Oct 7th, 2019. I already had a new offer from another company, so I decided to leave the current office. I got tax clearance and submit m passport to process the cancellation of the visa. However, the amount of tax hasn't completed for 2020, my current company said that they will deduct them from my last month's salary. I spent 5 working days but the cancelation of visa hasn't done and hasn't received the updated payroll.
Whether the new employer can process my visa application to get an approval letter for me if my tax due hasn't completed?
