Some VAT/tax transactions, including those with custom tax rates, EC VAT, reverse charges, or unusual tax transactions, will be converted as closely as possible but are likely to be different. We may use a standard rate of tax or No Tax and then add an adjustment to correct the tax amount if necessary. This could result in some boxes in VAT/Tax Returns being incorrect even if the Balance Sheet amount to be paid or refunded is correct.
For more information, please refer to our post-conversion tasks page and also the Tax Returns Don’t Agree page.
Depending on the system you’re converting from and the transactions present, the conversion may result in some rounding differences due to the way VAT/tax or line amount totals are calculated differently between systems.
