The error message when submitting the gift tax return 2026 is caused by the input fields for contact details in the return. If the checkbox for “The contact person is a legal entity” is unchecked, we advise checking the other fields under contact details and resubmitting the return.
We are working on being able to submit the returns where the contact person is a legal entity and you have checked this box. We will update this page as soon as more information becomes available.

You may experience that gift tax returns for the year 2026 are rejected with the error message: "...BD-X-1405: - - [error] BR-BD-16.4.110:...". A workaround is to resubmit the return. We are investigating this issue, and we will update this page as soon as more information becomes available. Our apologies for the inconvenience.
