Delaware participates in the Combined Federal / State Filing Program, but Delaware taxpayers must still file 1099-MISC and 1099-R forms directly with the Delaware Division of Revenue.

Delaware accepts 1099 information in three formats:

• Online
• Magnetic Media
• Paper

Please see our W-2 and 1099 reporting FAQs for details.

Duplicate 1099 Returns

Each year the Delaware Division of Accounting sends IRS Form 1099-MISC and 1099-NEC to all applicable service providers. Duplicate 1099s are available upon request.

For additional information please visit Division of Accounting’s website https://accounting.delaware.gov/suppliers/ or call Division of Accounting’s 1099 Help Line at (855) 846-7524.
