My Taxpayer Can’t Create Their Taxes to Go Account Because It Won’t Send Them a Code.

If a client is unable to receive the verification code, check whether the client is using T-Mobile or not. We have had problems with T-Mobile rejecting MFA codes to mobile phones. To solve this, have them contact T-Mobile to correct the problem on their phones. 

In case your client doesn’t use T-Mobile, ensure that they use the correct phone number to create their accounts.
