Zoho Books 1099 export: check it before IRIS

Getting the file out of Zoho Books

1. Track the vendors. In each vendor's Other Details tab, tick the option to track payments for Form 1099 and enter the Tax ID.
2. Generate Form 1099 under Taxes, Form 1099: choose the filing year and the form, map your expense accounts to the boxes, select the vendors and review the details.
3. Export for Filing. On the 1099 Report page, choose Export for Filing, complete your organization's Tax ID, name and address, and export the CSV.

What to check before you upload

• The $2,000 threshold. For payments made in 2026, the threshold for most 1099-NEC and 1099-MISC boxes is $2,000. Zoho Books' help page still lists $600 limits, so look for vendors under $2,000 that you may not need to report. The tool flags them.
• The payer phone number. Zoho asks you to type it in by hand when you export. Without it, IRIS returns business rule S1H001.
• The template for the tax year. IRIS checks the header row against the template for the tax year you file. If your export was built for another year, match the header to the template you download inside IRIS.
• File size. IRIS takes at most 250 records and 100KB per file.
• The new 2026 boxes. Tax year 2026 adds boxes for cash tips, tipped occupation codes and overtime. See what changed for 2026.

Drop the export into the IRIS CSV tool. It recognizes IRIS-format files, checks every row against the IRS rules, and splits the result into upload-ready files.
