So I take it from the onset you have been using the guides as a primary source of reference.

I agree. It is likely he renamed the “Tax payable” system account to “2000 - Tax payable” and left the the tax codes with this default account. When Manager was updated it didn’t update the tax codes to link to the renamed account and instead linked them to the new default (“Suspense account”). In which case this maybe considered a Manager update bug.
So I would have thought, not the sort of problem I would expect to find a solution in the guides. Errors caused by updating Manager to a later version are more typically discussed in the forum.
I agree the logical guide to look at for suspense errors is the Suspense guide, not chart of accounts or tax codes guides.
Perhaps more useful information earlier would have been:
Manager’s handling of the account “Tax payable” has recently changed. From Releases page
In the past it was a special system account automatically created when a tax code was used, and the default account in all tax codes unless a specific account was selected by the user. Now “Tax payable” is an ordinary account (which can be deleted or renamed if present at all in a COA), and all tax codes default to “Suspense account” unless explicitly set to a specific account.
The Tax code guide has been updated to reflect this change and if Managers version update code does not automatically implement the conversion you will need to manually configure the account used by each of your tax codes, see the updated guide on tax codes for details.
