It would be a good idea if we will have the option to insert a starting date from where the non-deductible VAT % will apply from. And have the option to recalculate the entries that are posted in a given period if they match with the non-deductible VAT %.

The case can be that from the local government changed the percentage for the deductible VAT from a given date and then we can make sure that posting after this date then will be posted with the right deductible VAT.

Companies can also have that their deductible VAT percentage depends on the split between turnover with or without VAT. The company will have a budget percentage and when the fiscal year ends then they can calculate the split and change the percentage. In this case it will great to have a job to make entries in VAT Ledger Entries and General Ledger Entries that correct to the right deductible percentage.
