Dear Software Developer (SD):

The information contained on this page is for those re-creating Delaware tax forms.


Please Note: To include a Delaware tax return in your software package, each form must receive OCR Approval by the Delaware Division of Revenue. 2D Barcode forms will require additional testing and approval.


Step 1: Per new FTA guidelines, SDs are required to submit a Letter of Intent (LOI) at the start of the design year. The first step to be included in the LOI approval process is to send an email to REV_MeF_Support@state.de.us. You will receive instructions on obtaining and completing your LOI. Once your LOI has been accepted, you may begin the forms approval process.


Step 2: Design forms as they appear on the following pages: Business Forms, Personal Forms

  • Software Developer forms must match Delaware's form field sizes, placement, and anchor marks exactly - see the General Form Specifications document.
  • All forms require OCR Approval unless otherwise noted. 2D barcode forms require additional testing and approval. (More info below)
  • All forms - even 2D Barcode forms - require a 1D barcode: see the General Form Specifications document.


Step 3: Determine if your form requires OCR or 2D Barcode Approval - do not mix OCR and 2D submissions.

All submissions must mimic what your users will submit using your software package. All PDF files should be saved at actual size.

There is no separate scanline testing for coupon forms this year. Scanlines will now be tested during the OCR Approval process.

Approval Process
  • Field borders should be 1-point thickness, in black with 8% opacity. If you can't do 8% opacity, then remove field borders completely.
  • Alpha characters should be in all caps.
  • No commas in numeric fields; no dashes in TPID.
  • No dashes in zip codes; please privide 9 digit zip codes in your test data samples.
  • Save forms as actual size: provide 1 full-fill sample and 2 test data samples via email; do not mail samples.
  • Each form should be saved as a separate file; do not combine multiple forms into one PDF.
  • Include your NACTP number in the PDF file names.
  • Email your PDF samples to DE_DOR_Forms@state.de.us, and include your NACTP number in the title of your email.
2D Barcode Testing:
  • Available for Forms 200-01, 200-02, 1100, and 1100S
  • Whenever possible, provide 2D barcodes on these forms
  • Specs and approval process - email DE_DOR_Forms@state.de.us for more information.

Please Note:

  • Whenever possible, forms will be approved/tested within 7 business days.
  • Forms will be marked "DRAFT" until finalized.
  • You can only receive approval on forms marked "FINAL."
  • Once you receive approval on a FINAL form, your form will be marked certified. If scanning issues arise as the tax season progresses, we will work with you on making changes.
