Czech President advances first Tanzania income-tax treaty towards ratification

The signature is a material Czech ratification milestone, not entry into force. The agreement will become operative only after both states complete their domestic procedures and exchange diplomatic notifications. Czech parliamentary consent had already been given in October.^[1][3][4][5]

Permanent establishments and source taxation

The agreement, signed in Dar es Salaam on 14 May 2025, covers Czech individual and corporate income taxes and Tanzanian taxes imposed under the Income Tax Act, Cap. 332. Article 5 creates a permanent establishment where a construction, assembly or installation project, or connected supervision, continues for more than six months. A service permanent establishment can also arise where services, including consultancy or management, exceed six months in aggregate within any 12-month period.^[2]

For qualifying residents that are beneficial owners, source-state tax is capped at 7.5% of gross dividends, 10% of gross interest, 15% of gross royalties and 12.5% of gross fees for managerial, technical or consultancy services. The technical-services article excludes employee services, teaching and services acquired by an individual for personal use. The limits are qualified where income is effectively connected with a local permanent establishment or fixed base, and excessive related-party payments remain subject to arm’s-length limits.^[2]

Relief and anti-abuse

Article 24 generally uses foreign-tax credits to relieve double taxation. Tanzania also grants an underlying credit for Czech corporate tax where a Tanzanian-resident shareholder owns at least 5% of the Czech payer. Treaty access remains subject to Article 29’s principal-purpose test and domestic anti-avoidance law.^[2]

Do not apply the rates yet

Under Article 31, the agreement enters into force when the later diplomatic notification is received. Withholding provisions then apply to income paid or credited from 1 January of the following calendar year; other income-tax provisions apply to taxable years beginning from that date. Groups should identify affected payments, service projects and construction activity now, while continuing to apply existing domestic law until entry into force is confirmed.^[1][2][5]
