Tax in UAE 2025: A Guide for SMEs & Startups
In an era of rapid economic diversification, UAE corporate tax 2025 has become a critical focus for startups and small-to-medium enterprises (SMEs). With value-added tax firmly entrenched since 2018 and a new business tax regime effective for financial years from June 1, 2023, understanding your obligations is no longer optional—it’s essential for survival and growth. This guide decodes both VAT in the UAE and the corporate tax framework, offering actionable insights and UAE-specific strategies tailored to entrepreneurs and SME owners.

Why VAT & Corporate Tax Matter to UAE SMEs
- SMEs drive 94 % of all UAE companies, account for 86 % of private-sector employment and contribute over 60 % of non-oil GDP
- VAT (5 %) introduced from January 1, 2018 applies to most goods and services, with zero-rate on exports and specific essentials
- Corporate tax launched for fiscal years starting June 1, 2023 at a standard 9 %, with a 0 % rate for qualifying free zone persons under certain conditions
- 15 % minimum top-up tax on large multinationals begins January 1, 2025 under the OECD’s global minimum tax agreement
Together, these regimes mean every UAE-based or UAE-connected business must revisit its accounting processes, supply-chain agreements, and growth strategies. Let’s break down who needs to register, how to comply, and where to seek expert support.
