2. Contractors or suppliers domiciled in the Republic of Panama must accompany their invoices with current and valid clearance certificates issued by the Ministry of Economics and Finance, (Internal Revenue Directory) as well as from the Social Security Institution. Invoices associated to contracts or purchase orders lesser or equal to $500.00 are exempt from this requirement.
Causes for Returning Invoices
An invoice is defective and shall be returned when:
1. Does not comply with the requirements above described.
2. The number of the contract or purchase order indicated on the invoice is mistaken.
3. Makes reference or includes goods or services associated to more than one contract or purchase order.
Tax Exemption
As stipulated in the Article 43 of the Panama Canal Authority Organic Law, all goods object of a contract, consigned to the Authority and identified as such on the contract as well as all services rendered to the Authority, are exempt from the payment of any national or municipal levy, tax, duty, fee, rate, charge, or contribution.
1. Requirements that must fulfill the clearance certificates (income tax and social security contributions) submitted along with the supplier’s invoice:
2. Procedure for submission of clearance certificates
The Panama Canal Authority shall make a payment within thirty (30) calendar days after the submission of a complete invoice and delivery of the object of the contract or purchase order.
Calculation of the thirty (30) day-period will begin the day after the latest of these dates:
1. Date in which the proper invoice (along with the clearance certificates and any other document required by the Authority) is actually received by the designated billing office.
2. Date in which the office designated in the contract or purchase order as “Ship To” actually receives the goods or services object of the contract.
3. Date in which the office designated in the contract or purchase order as “Ship To” actually accepts the goods or services object of the contract, when the contract or purchase order includes an inspection and acceptance clause.
* When a purchase order or contract includes an inspection clause, such clause must specify the number of days required for the inspection of the goods. The days established for the inspection will not be taken into account within the 30-day period to calculate the due date for payment. In those cases, the acceptance date shall constitute the goods delivery valid date.
The 30-day period shall be reduced if the contractor offers to the Authority a prompt payment discount.

When a delay occurs in the payment process attributable to the Authority, interest estimated shall be recognized and paid automatically for the delay period at the LIBOR rate at three (3) months, valid at the beginning of each quarter.
The Authority shall accept a request from a contractor for assigning payments due or to become due under a contract to a financial or governmental institution. A payments assignment contract must fulfill the following requirements:
The payment assignment contract must be submitted with the following documents:
The payments assignment contract must:
“Invoice corresponds to a contract with a payment assignment”
The Authority shall make a payment within thirty (30) calendar days after the contractor submits a complete invoice along with any required documents and delivers the goods or services, object of the contract or purchase order.
To reduce the 30-day period to make a payment, the Authority accepts the offering of prompt payment discounts. Discounts will be taken whenever they are proven to be economically beneficial for the Authority.
A prompt payment discount may be offered before, during or after a supplier invoice is submitted. Furthermore, discounts may be offered for a single invoice or for all invoices submitted to the Authority by the contractor. In doing so, the contractor must send, by fax, a written notice offering the prompt payment discount. See an example of the notice.
Calculation of a discount payment date:
To calculate a discount payment date the following parameters have to be taken into consideration:
The latest of the dates established by the Authority for processing the payment. Refer to Payment Terms.
The discount offered.
Examples of discount payment date calculations:
