I’ve used TaxAct for many years and find the platform intuitive and easy to navigate. In recent years there have been increasing hoops to Jump through with regards payment cards and U.K. addresses. There was a spectacular workaround that worked brilliantly where you’d use the first line of your address and the rest would be TaxActs. This worked without fault, until this season. I was getting a constant decline under this method, even trying a VPN to no avail. I had Major issues with MFA, as the old and much loved email authentication method was removed, leaving the Google App or a text to mobile. I was able to overcome this, (again via a brilliant suggestion on this forum (can’t find the original post), with disposable mobile numbers. Anyhow as my account had been locked out by TaxAct I had to put in my previous U.S address and other information to get the account reenabled. As a final attempt I used that Stateside address in the payment section and it all worked, payment accepted! How my U.S. bank card worked with the old address is a mystery. Any other online purchases and it’s my U.K.address with that card… strange indeed.
