Terraform and AWS Tag Policy

Hi guys, i have a question. On my AWS i have Tag Policies and assigned to a user whereby for example an EC2 instance cant be made without the mandatory tags within the policy (Department: HR, Finance, Customer: XXXX) etc.)

If i make a terraform script to make a simple EC2 instance, do i need to add in the tag syntax in the script regardless and if i dont will it stop me?

tags = {
Deptartment= “test”
