The warning means that we haven't received your monthly instalment.
In order to resolve the issue you can either:
1. Log on to the TaxCalc website using your registered email address and password and click on My Account > Account History, where you will see a 'Resolve' button to submit your payment.
2. Call your account manager to process the payment on the phone
3. Email sales@taxcalc.com where one of the team can look into your account and advise accordingly.
If access to your TaxCalc has been suspended due to the payment being outstanding for 7 days or more, once payment has been received, immediate access will be restored. An email will have been sent to the registered account holder to advise of the payment failure.
