Bring your 2020 Form EA, 2020 Form BE, CP21 given by employer and also use 2020 paper BE form to fill in your taxes for 2021 (simply strike off 2020 and replace with 2021). Make sure your employer has already informed LHDN about your intention to depart Malaysia for employment abroad. LHDN will tell you to wait up to 14 days while they process your tax clearance. Remember to ask for point of contact if it exceeds 14 days.

Once the process is done, they will send a letter to your employee for them to release your salary. You will also receive a copy in your mailbox.

I'm also going over to SG so the above is my personal experience dealing with them in the past fortnight. All the best!
