# 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.
