What document is NOT required when applying for Widow's pension benefits?

The answer identifying tax return as the document not required when applying for Widow's pension benefits is accurate because tax returns are not a standard requirement in the application process for these benefits. Typically, when one applies for a Widow's pension, the essential documents are primarily focused on establishing the marital relationship and the eligibility of the deceased spouse.

The marriage certificate is crucial as it confirms the legal union between the applicant and the deceased. This document serves to establish the nature of the relationship, which is fundamental when determining eligibility for the benefit.

Similarly, the death certificate is required to prove that the spouse is deceased, confirming the beneficiary status of the applicant. It is a foundational document in this context.

The birth certificate may be requested if the application process involves verifying the identity or age of the applicant or their dependents, but it is not universally required for all Widow's pension applications.

In contrast, while tax returns may provide additional financial information, they do not directly pertain to the marital or status qualifications necessary for the Widow’s pension application, which is why they are not included as a required document.
