What it means
In the VAT breakdown, the VAT amount of one VAT category (BT-117) has more than two digits after the decimal point. Every digit after the point counts, so 197.4 is fine but 197.405 fails and so does 197.400.
Why it matters
The VAT breakdown shows how much VAT is due at each rate, and the total VAT is the sum of these amounts. A VAT amount with extra decimals cannot be booked as stated, so the file fails validation and is rejected.
How to fix it
For each VAT rate, multiply the taxable amount (BT-116) by the rate, round the result to two decimals and enter it as the VAT amount of that category. The total VAT (BT-110) is then the sum of these rounded amounts. For categories without VAT, such as zero-rated or exempt, the VAT amount is 0.00.
The rule as published
The allowed maximum number of decimals for the VAT category tax amount (BT-117) is 2. Business terms: BT-117
