Overview 

West Virginia allows taxpayers to upload certain supporting documents electronically when filing their state return. This is done through the WV – Optional Binary PDF Attachments form. 

What Is the Optional Binary PDF Attachments Form? 

The Optional Binary PDF Attachments form is a way to securely provide supporting documentation to the West Virginia State Tax Department when filing electronically. 

• It is primarily used for items that require proof or additional verification. 

• Most taxpayers do not need to use this form unless the state requests documentation. 

When Should You Use This Form? 

You may need to upload PDF attachments if: 

• The West Virginia State Tax Department requests original documentation. 

• You are required to submit special support documents that cannot be entered directly into the tax return. 

• You are providing documentation for credits, deductions, or adjustments that require validation. 

Note: Most income and withholding information do not require you to submit original documents.
