Intro 0:00

In this video, you'll create your Delaware 1099-NEC IRIS XML file with the Export Wizard in W2 Mate. Delaware takes 1099s in the IRS IRIS XML format, and the wizard builds that file in four short steps. Delaware wants a 1099-NEC for every Delaware resident and for work done in Delaware by nonresidents.

What goes into the 1099-NEC IRIS XML file 0:26

Here's the 1099-NEC, and the IRIS XML that W2 Mate writes for it. Box 1a, nonemployee compensation, becomes NonemployeeCompensationAmt. Boxes 5, 6 and 7 become the state group: DE, your Delaware state ID number, the state tax withheld and the state income. The recipient's tax ID goes in with its type. So in W2 Mate, type each one with its dashes: SSN as xxx-xx-xxxx, EIN as xx-xxxxxxx. That's how the file gets the right TIN type and goes through.

Before you start: set Box 6 to DE 1:08

Before you start, make sure Box 6 on every 1099-NEC you're filing with Delaware is set to DE. To be safe, open Tools > Other Recipient / 1099 Tools > Update Box 6 (State, Payer's state #) for multiple 1099-NEC recipients. Pick DE, and enter your Delaware withholding account number, if you have one.

Open the IRIS XML Export Wizard 1:33

Then start the wizard from the E-Filing menu. Point to 1099 IRIS XML Format (For State Upload), then click Export 1099-NEC Data as IRIS XML File.

Step 1: Payer 1:48

Step 1 shows the payer — the business that issues the forms. Check the name, tax ID and address. To fix something, click Review / Edit Payer. Here you can update the payer's TIN type and number, the name and the address. Click OK when you're done. Then tick the box to confirm, and click Next.

Step 2: Transmitter 2:10

Step 2 shows the transmitter, who sends the file, and the contact person Delaware will reach if there's a problem. To change any of it, click Edit Transmitter. This screen has who's sending the file, the company address for letters from the state, and the contact person. Click OK. Then click Next.

Step 3: Recipients (select Delaware) 2:32

Step 3 lists everyone who gets a 1099-NEC. Checked recipients go into the file. Delaware wants every Delaware resident and every payment with a Delaware source. With Box 6 set to DE on those forms, choose DE in the Box 6 state list and click Select Only This State. To double-check, choose DE in the Address state list. Every recipient with a Delaware address should already be checked. If a recipient shows in red, the Problem column tells you what to fix before you upload. Click Next.

Step 4: Output file 3:09

Step 4 is where the file is saved. Click Browse to pick a different folder. Leave the testing box unchecked for your real filing, and click Finish.

File created: check the totals 3:20

W2 Mate creates the file and shows the totals inside it. Compare them with your records: 5 Delaware forms and the Delaware tax withheld. Click Copy Path, so you can find the file on the upload page.

Upload to DE Delaware Taxpayer Portal 3:35

Now log in to the Delaware Taxpayer Portal, find the 1099 upload, and choose the IRIS XML option when the portal offers it. Delaware is moving its 1099 uploads to the IRS XML format, so if you don't see that option yet, contact them before you upload. Keep the confirmation for your records. If there are errors, fix them in W2 Mate and upload again. 11 or more W-2s and 1099s in total must be filed electronically through the portal. The file is due January 31, and your filing isn't complete until Delaware accepts it. For help, email the Delaware Division of Revenue at dor_w2_1099@delaware.gov. That's it. Your Delaware 1099-NEC IRIS XML file is ready. If you have questions about W2 Mate, email sales@realtaxtools.com or call 1-800-507-1992.

The steps at a glance

  1. Before you start: set the state box to DE on every form you file with Delaware (Tools › Other Recipient / 1099 Tools › Update … for multiple recipients), and enter your Delaware withholding ID. Type your Delaware withholding account number as you use it, like 012345678.
  2. Type tax IDs with dashes: SSN as xxx-xx-xxxx, EIN as xx-xxxxxxx, so the file gets the right TIN type.
  3. Open the wizard: E-Filing › 1099 IRIS XML Format (For State Upload) › Export … Data as IRIS XML File.
  4. Step 1 and 2: confirm the payer and the transmitter (use Review / Edit to fix anything).
  5. Step 3: With Box 6 set to DE on the forms for Delaware residents and work done in Delaware, choose DE in the Box 6 state list and click Select Only This State. Then choose DE in the Address state list to double-check every Delaware resident is checked.
  6. Step 4: pick where to save, leave Testing unchecked, and click Finish. Check the totals, then Copy Path.
  7. Upload the file to Delaware Taxpayer Portal with W-2/1099 upload; pick the IRIS XML option when the portal offers it. Keep the confirmation for your records; your filing isn't complete until Delaware accepts it.

What W2 Mate writes for Delaware

This is the state part of each 1099 in the IRIS XML file W2 Mate creates for Delaware. Open your file in Notepad to compare it with yours. The element names come from the IRS IRIS XML schema; see the IRS page IRIS schemas and business rules.

Common problems

Issues our support team sees most when customers file state 1099s:

The file has fewer recipients than I expected.

Either those recipients aren't in W2 Mate yet, or the state box on their forms isn't set to DE (Box 6 on the 1099-NEC). Use Tools › Other Recipient / 1099 Tools › Update … for multiple recipients to set DE on all of them, then export again. In Step 3 of the wizard, compare the number of checked recipients with your records before you click Next.

The state rejects a recipient because of the TIN type.

Type the recipient's tax ID with its dashes: an SSN as xxx-xx-xxxx and an EIN as xx-xxxxxxx. W2 Mate reads the dashes to tell an SSN from an EIN and writes the right TIN type into the file. Fix the TIN in W2 Mate, then export again.

The state says the file is in the wrong format.

Make sure you uploaded the IRIS XML file you saved in Step 4 of the wizard, not another file (for example an older Pub 1220 file or your federal IRIS file). Click Copy Path at the end of the wizard and paste it into the upload page's file box so you pick the right one.

The state doesn't accept my Delaware withholding number.

W2 Mate puts the number in the file exactly as you type it, so enter it in the format Delaware gave you (see "What should the Delaware withholding ID look like?" under Questions). Type it in the Employer State ID field on the Company General Information tab, and use the Update tool for multiple recipients so every form has it, then export again. If you're not sure of the number, contact the Delaware Division of Revenue.

Questions

Does Delaware accept 1099s in the IRS IRIS XML format?

A September 2026 Delaware notice moves 1099 uploads to the IRS IRIS XML format, but Delaware's FAQ still describes Pub 1220 files. Pick the IRIS XML option in the Delaware Taxpayer Portal when it's offered, and email dor_w2_1099@delaware.gov if you don't see one.

When are Delaware 1099 files due?

A September 2026 Delaware Division of Revenue notice moves 1099 uploads to the IRS IRIS XML format with a January 31 due date. Delaware's FAQ still lists the older Pub 1220 format and dates, so confirm the due date with the Division of Revenue before you file.

Which 1099s does Delaware require?

1099-NEC for Delaware residents (wherever the work was done) and for nonresidents for work done in Delaware.

What should the Delaware withholding ID look like?

Type your Delaware withholding account number as you use it, like 012345678.

Who do I contact about Delaware Taxpayer Portal?

Email the Delaware Division of Revenue at dor_w2_1099@delaware.gov.

Does Delaware take IRIS XML files yet?

A September 2026 Delaware notice says 1099 uploads move to the IRS IRIS XML format, but Delaware's W-2/1099 FAQ still describes Pub 1220 files. In the Delaware Taxpayer Portal, pick the IRIS XML option when it's offered; if you don't see one, email dor_w2_1099@delaware.gov before you upload.

Do I have to file electronically?

If you have 11 or more W-2s and 1099s in total, yes, through the Delaware Taxpayer Portal (registration required). With 10 or fewer you may mail paper forms to State of Delaware, Division of Revenue, P.O. Box 830, Wilmington, DE 19899.
