Article ID: 2633
Last updated: 28 Jan, 2022

Below is a list of notable issues that have been reported in recent versions of TaxCalc since their release. Other issues may exist that have not yet been confirmed or investigated, or are trivial/cosmetic. This should be read in conjunction with our article How are software enhancements and issues prioritised at TaxCalc?

Tax Return Production

Issue Description Workaround Case reference Resolution schedule

In some cases, a filing error which contains the following is experienced:

ChRIS 0 Computations The item '{}MainPoolCarsWithLowCO2EmissionsFirstYearExpenditure' is not dimensionally valid. 

We recommend waiting for the Winter release and attempting after this has been applied. PROD-7013 Released in v12.1.020
In some cases, where fetching for SA100s or VAT Returns the HMRC Portal window comes up blank and you cannot proceed.

We have found the following steps help resolve the issue:

  • Close TaxCalc
  • click on Start and type %appdata%, and press return
  • Click on AppData on the menu, if it defaults to Roaming
  • Navigate to the folder:

Local\Acorah Software Products\TaxCalcHub\ cache\QtWebEngine\Default\Cache

  • Delete the contents of this Cache folder
  • Log into TaxCalc and try to Authorise again.
PROD-6923 Released in v12.1.020
Tax Return failing to open or crashing relating to clients with Partnerships

- For clients who are no longer in a partnership but still have the records on PM, If you delete the relationship and then go to the return it will no longer crash.

- For the clients who are still in a partnership, instead of deleting the partnership, you can create a partnership return for the same year and it will no longer crash either.

- Alternatively, you can go to File \  Print Tax Return or File \ Submit to HMRC. This avoids going to Check/Finish but when submitting still completes the same verification/checks and will prompt if there is a problem.

PROD-6991 Released in v12.1.020
In some rare situations TaxCalc is prompting to re-authorise the fetching token for MTD VAT & SA, even though the token expiry date has not been reached. Investigations around this are continuing. In the meantime you can delete and create a new token or we have found that if you wait 1-2 hours and try again this has shown to have a positive effect. PROD-6344 Released in v12.0.007
Locking SA800 return causes SA100 validation message about changes made on SA800 return Ignore the validation error or refresh import PROD-5924 Released in v12.0.007
CGT - Residential Property - Tax paid Box 12 is being rounded down Manually round the tax paid value up to the nearest pound PROD-5872 Released in v12.0.007
CT600 - incorrect validation for box 895 when an amount hasn't been entered for tax credits ignore the validation message and proceed with submission as the return will file online successfully PROD-5449 Released in v12.0.007

In some cases a CT600 capital allowance check and finish message is presented as:

"Capital Allowances Grid — The Written Down Value brought forward in capital allowances does not match the Written Down Value carried forward from the previous tax return. Please check your entries and if required amend as necessary."

If you are happy with your figures this message can be ignored and you can continue as needed. PROD-5244 Released in v12.0.007
Read only message appearing in Notifications Panel (Non-practice users) Usage of the application is retained so users can ignore the Notification and proceed with required entries. PROD-5165 TBC
In some cases when filing a CT600 there is an error relating to "Director in Generic Dimension"

In Accounts Production:

  1. Go to Notes > Edit Notes
  2. Locate the Report of the Director's > Small Company Rules section
  3. Turn the note on
  4. Add the date and director name for signing,
  5. Turn the note off again.

On the CT:

Go to CT600 > Attachment Management and refresh the attachment and file.


Other modules/General

Issue Description Workaround Case reference Resolution schedule
Company Incorporations. In some cases a Transaction Error is presented, but the Incorporation has been successful.

Do not poll for updates via Notifications at the top-right corner of TaxCalc.

Please go to the Company Incorporator module itself and click Finish and poll from here.

Communications Centre - in some cases emails to BT, SKY or Yahoo clients are not being received or a rejection notice showing details including  "bare lines" is received This is currently being investigated PROD-7016 / PROD-7054 Released in v12.1.020

AML Centre - Slow loading of Firm Wide Compliance  Wait for the module to load, once it has opened navigation within the module is back to normal. PROD-5461 TBC
In some cases users are not being shown within Admin Centre \ Users.

We have seen this when there is a failure during the login process.

We have also noted a link to enabling 2FA and not completing the login. In this situation a workaround is to log in as 'admin' and go to Admin Centre \ Users and then Bulk turn off 2FA. This will allow the user to log in as expected, and they will be listed on Admin Centre \ Users after this.

PROD-4495 Released in v12.0.007
In rare cases eSign envelopes are stuck in processing and will not be sent to the client, but may not be visible as this status from within TaxCalc.

We believe we have identified the cause of this issue. Please ensure that any external PDF files run through the File > Save As routine and re-create the envelope to send. 

PROD-6241 Released in v12.1.020
Any envelopes which have generated a status of "processing" cannot be deleted from the application

Please contact with details of the affected envelope so that we can review the status and confirm the behaviour for you.
