Abstract: Abstract. The article substantiates the need to delimitate the customs legislation and tax legislation. The subject of the study is related to the regularities associated with customs payments. The author notes that customs payments represent the totality of customs duties and customs fees.

Customs payments shall be governed by the provisions of customs legislation. The VAT should be excluded from the list of customs payments.
