Kuwait's 5 percent retention on contract payments: what companies paying foreign contractors must do
A Kuwaiti company paying a foreign engineering firm for work on a project cannot simply pay the full invoice. Kuwait's tax rules require it to hold back 5 percent of each payment until the contractor produces a tax clearance certificate. Paying in full can make the Kuwaiti company liable.

A Kuwait City developer hires a European engineering firm for KWD 480,000 of design and supervision work on a residential tower. Each month it pays 95 percent of the firm's invoice and holds 5 percent. At the end of the project the firm asks for the retained amount. The developer replies that it needs to see the firm's tax clearance certificate first. That is the rule.
The retention rule
Kuwait taxes foreign companies on income from activities in Kuwait. To secure that tax, the income tax executive regulations require Kuwaiti entities that contract with contractors and subcontractors to:
- notify the tax department of the contract,
- retain 5 percent of each payment, or of the final payment if that is larger,
- release the retention only when the contractor presents a tax clearance certificate from the Ministry of Finance.
The rule covers foreign companies doing work and services in Kuwait.
Why the payer cares
If a Kuwaiti company releases the retention without clearance, it can be held liable for the contractor's unpaid tax. The 5 percent is the payer's protection, so finance teams hold it firmly.
Planning with contractors
- Put it in the contract. State that 5 percent is retained until clearance, so the contractor plans for it.
- Notify the contract to the tax department as required.
- Track retentions per contractor and project.
- Release promptly once clearance arrives.
Paying the 95 percent
The regular payments still have to reach the contractor. Foreign contractors receive international transfers from Kuwaiti banks, usually in dollars or euros. Agree the currency and who bears transfer charges in the contract.
Where Rivet fits
Rivet does not handle Kuwaiti tax filings or clearance. A Rivet business account accepts registered companies after verification, including Kuwaiti companies, subject to local rules, and pays contractors in 120+ countries from dollar and euro balances, with each payment matched to its invoice so retained amounts are easy to track. Rivet is not a bank; regulated partner institutions hold the funds.
