As the main outcome of the research, the author describes peculiarities of the legal regulation of concluding a public contract with a single supplier, subcontractor or performer as follows: 1. In some cases, public contract for single-source procurement may be concluded verbally; 2. it is allowed to agree on a contract price by setting formula or maximum amount instead of a fixed amount; 3. In all cases of concluding a contract for single-source procurement with a physical entity, a contract price must be reduced by tax payment amount (Part 13 of Article 34 of the Procurement Law) disregarding the fact that Part 15 of Article 34 of the Procurement Law provides an opportunity not to do it. This is explained by the fact that in these legal relations a customer acts as a tax agent of a supplier, contractor or performer.
