I have tested all standard Dutch VAT-codes both with a sales invoice as well as with a purchase invoice and the VAT Tax-Return Report (Concept BTW-aangifte) is now showing the right figures at the correct lines in the report (aangifte). However all individual amounts shown at lines 1 until 4b and 5b should be rounded to zero digits. The subtotals at lines 5a and 5c should be the totals of the to zero rounded amounts. In a test situation, because of not being rounded to zero digits, 21 + 21 added up to 43 in the report,which is not correct. Could you please change this and let me/us know.
