Query names with special characters

An issue has been reported when editing a saved query with special characters in the name (& _ % * ^ ). It only happens when you add a new field to a saved query and run it, when you go back and edit the query, the name at the top has some strange characters added and the system treats it like a new query. Query names with no special characters are working correctly. We are currently working on a fix to be released as soon as possible.

Add new button on employee screens

An issue has been reported when using the Add new button on a screen where the ability to copy an existing record is enabled, see The Job and Salary screen as an example. The Add new button is behaving the same as copying a record. We are currently working on a fix and will have this released as soon as possible.

Time and Attendance screen

An error has been reported when accessing the Time & Attendance screen. This screen is linked to the module T&A. We are currently working on a fix and will have it released as soon as possible.

Workflow data triggers

We are aware of an issue with workflows not triggering using the Data trigger event. We are working on a solution and will look to have this resolved as soon as possible.

Entitlement year screen

We are aware of an issue on the entitlement year screen where both Days and Hrs & Mins are being displayed in the Entitlement section at the bottom of a record. This is a display issue only. We are currently looking at the issue and will have a fix released as soon as possible.

HMRC have announced changes to the Approved Mileage rate for the first 10,000 miles for Cars and Vans..

The tax free amount that employers can reimburse for employees using their own vehicle is increasing to 55p for the first 10,000 miles for tax year 2026 to 2027. The rate of 25p per mile remains for each business mile over 10,000 miles remains

We have started work on these changes required to update the rates for 2026/27. The changes to the rates will be updated as part of the next Cascade release, which is scheduled for Wednesday June 3rd.

Further information can be found here Vehicle Mileage Schemes 2026/2027

10th April 2026

HMRC have made us aware of an issue regarding to the uprating of statutory payments.

Historically, all statutory payments will be uprated from previous tax year on the 1st Sunday in the new year, which was the 5th April for 2026/27.

On the 8th April, HMRC have advised that for the 2026/27 tax year, the uprated date should have actually been the 6th April for the following statutory payments:

  • SPP

  • SAP

  • ShPP

  • SNCP

  • SPBP

As part of the year end procedures when uprating statutory payments for 2026/27, Cascade will have used 5th April for these statutory payments as per initial guidance.

HMRC and the Department for Business & Trade recognise that this error has been identified after the start of the new tax year, and that payroll products for 2026/27 have already been released. They have determined that as the issue only impacts a small number of customers not resulting in any detriment, they will take a pragmatic approach and not pursue any unintentional errors where the alternative date of 5th April has been applied for uprating these statutory payments for 2026/27 tax year. Therefore, based upon this advice, no further changes regarding uprating statutory payments will be made to Cascade.

The statutory rate applied by Cascade can be manually amended in Input Variable Pay if required.

Actions buttons on some vertical screens

We are aware of some screens where the Action buttons along the bottom are not being aligned further up the screen after the data has loaded..

The areas in question are;

In HR any of the catalogues (Query and Groups catalogue etc)

In payroll, Application data > Pay Element > Groups > Add

The areas in question are still usable so we will be working towards correcting the issues in the coming releases.
