When generating the sales tax report, there's no requirement to include data from past years. Only the Tax Reporting for Service Tax necessitates incorporating the previous year's accounting. This is necessary because any outstanding bills pending payment for over 12 months must be reported to RMCD in the subsequent year.
When this happens, please check the following setups:
Open Setup, General Setup, Last Year Accounting.
Remove location for Last Year Accounting.
Click OK to save the changes.
