Rejection 1026: Error "IBS rate of the UF must be 0.1% for documents issued in 2026"

This rejection happens when the NF-e has an issue date in 2026 and the IBS rate of the UF informed in the item is different from the value required by SEFAZ.

What does this mean?

During the year 2026, the IBS legislation establishes that the IBS rate of the UF must be exactly 0.1%.
If any other value is entered (or if the field is left empty when required), SEFAZ will return Rejection 1026.

How to fix it in Sensio

  1. Go to Issue NF-e and open the invoice that got the error.

  2. In the Products section, click Edit on the invoice item.

  3. Scroll down to Item Taxes.

  4. Find the group for IBS (when available for 2026).

  5. In the field IBS UF Rate (%), enter 0.10.

  6. Save the item, check the invoice and issue again.

⚠ Attention: this rule is only valid for documents issued in 2026. For other years, the IBS rate might be different according to current legislation and SEFAZ updates.
