TDS REIMBURSEMENT FOR AWS

I suggest to open a billing support case from your account https://docs.aws.amazon.com/awssupport/latest/user/case-example.html - as the support team will be able to advise you better depending on the settings of your account.

It depends on the country and settings of address on your account, and also whether you are charged by AWS Inc, AWS EMEA SARL, AISPL, or other AWS entity (seller of record depending on the location) - https://aws.amazon.com/tax-help/ - the support team should be able to advise you better depending on your individual case.
