This article explains how to move from the 2025/26 tax year to 2026/27 in BrightCIS.  

Follow the steps below to set up the new CIS tax year when you access the BrightCIS site 

Generate a new tax year 

• Go to http://cis.brightpay.com/ in your browser.  
• Log in with your Bright ID
• When you sign in, BrightCIS will default to the 2025/26 tax year.
• Open the contractor you set up in 2025/26.  

• At the top of the screen, locate the Tax year selector (e.g. “2025/26”).  

  

• Click on 2025/26.  
• Choose Generate tax year from the options.
• BrightCIS will now create the **next tax year** for that contractor, carrying forward the relevant CIS setup so you can continue processing subcontractor payments in the new year. 
• Start Working in the New Year

If you use BrightPay for payroll as well, you can transfer **Gross CIS deductions** from BrightCIS into BrightPay so your overall HMRC liability (PAYE + CIS) is kept up to date.

Note - You can easily switch between the old and new tax years by clicking on the tax year at the top of the screen and selecting 2025/26. This will let you view or print any reports you need for that year.
