If you run a business in both the US and the UAE — or you’re planning to expand — understanding how each country taxes your company is not optional. Getting it wrong costs money. Getting it right can save you thousands.
The Basics: How Each Country Taxes Companies
The United States taxes corporations at a flat federal rate of 21%, plus state-level taxes that vary between 0% and 11.5% depending on where your business is registered. This means a company in Wyoming pays far less in state tax than one in California. The US also taxes worldwide income — meaning even profits earned abroad can be subject to US tax if your company is incorporated there.
The UAE introduced its first-ever Corporate Tax in June 2023, set at 9% on taxable income above AED 375,000 (approximately $102,000). Income below that threshold is taxed at 0%. Free zone companies may still qualify for a 0% rate on qualifying income, provided they meet specific substance and compliance requirements.
Key Differences at a Glance
- Tax Rate: US federal rate is 21% + state; UAE is 9% (or 0% for qualifying free zone income)
- Worldwide vs Territorial: The US taxes global income; the UAE taxes only income sourced within the UAE
- VAT: The UAE charges 5% VAT on most goods and services. The US has no federal VAT — sales tax is state-level and varies
- Tax Year: US fiscal year can be calendar or custom; UAE corporate tax year aligns with the financial year
- Filing Deadlines: US federal returns are typically due April 15 (with extensions to October); UAE corporate tax returns are due 9 months after the end of the tax period
Founder tip: If you hold a US passport and own a UAE company, the IRS may still want a slice of your UAE profits through GILTI (Global Intangible Low-Taxed Income) rules. This is one of the most commonly missed obligations for American founders abroad.
What This Means If You Operate in Both Markets
A dual-market business needs to plan its structure carefully. Holding companies, transfer pricing between entities, and tax treaty benefits all come into play. Without proper advice, you risk being taxed twice on the same income — or missing exemptions you’re entitled to.
The US-UAE tax treaty is limited, which makes professional guidance even more critical. Your accountant needs to understand both jurisdictions — not just one.
