Output VAT is the value added tax you calculate and charge on your own sales of goods and services if you are registered in the VAT Register. Output VAT must be calculated on sales both to other businesses and to ordinary consumers. VAT on sales between businesses must be specified in a sales document.
Output VAT must also be calculated when when you withdraw goods or services for private use from a registered business. If goods are withdrawn for use that is not liable to VAT under the VAT Act, VAT on withdrawals must be calculated unless the goods in question are capital goods that fall under the scope of the adjustment provisions for input VAT.
Input VAT is the value added tax added to the price when you purchase goods or services liable to VAT. If the buyer is registered in the VAT Register, the buyer can deduct the amount of VAT paid from his/her settlement with the tax authorities.
The seller's organisation number and the letters MVA must be stated on the sales document. If this information is missing from a paid invoice, you cannot deduct input VAT.
