2D Barcode Specifications

The links listed below will contain the final 2D barcode specifications for tax years 2017 and 2018 forms and are arranged by Maryland form number. Since we prefer the 2D barcode method for computer preparation of paper returns, vendors providing 2D barcodes will be designated as preferred software vendors for tax professionals.

For more instructions about 2D barcode processing, see Administrative Release 26.
