Bulk File Taxes

Bulk Filing via INTIME or SFTP

Customers submitting large files for certain tax types (listed below) can electronically bulk file these records with DOR in the following ways:

• If a file size is under 10 MB, manually enter or upload via INTIME. When filing securely via INTIME, bulk files do not require a file naming convention or encryption. An INTIME Guide for Business Customers is available. Additional INTIME guides are available.


• If a file size exceeds 10 MB, upload via SFTP. Registering for SFTP can only take place if a file has been rejected by INTIME for exceeding the 10 MB size restriction. When bulk filing via SFTP, it is required to follow the file naming convention and file(s) must be encrypted. A SFTP Bulk Filing Guide is available.

Schemas and file specifications for each tax type are available on their respective information page.
