Let’s face it: navigating corporate tax regimes can feel like a maze designed to trip up even the savviest entrepreneur. If you’re considering Brunei (BN) as a base for your company in 2025, you’re probably searching for clarity, efficiency, and—above all—a way to keep more of your hard-earned profits. Here’s a data-driven breakdown of Brunei’s corporate tax system, with actionable tips to help you optimize your fiscal footprint and minimize state-imposed costs.
Brunei Corporate Tax Rates in 2025: What You Need to Know
Brunei’s corporate tax regime is progressive in name, but in practice, it’s refreshingly straightforward. The tax rate is a flat 18.5% across all income brackets for most companies. Here’s how it breaks down:
| Taxable Income (BND) | Tax Rate (%) |
|---|---|
| 0 – 100,000 (approx. $0 – $74,000 USD) | 18.5 |
| 100,001 – 250,000 (approx. $74,001 – $185,000 USD) | 18.5 |
| 250,001 and above (over $185,000 USD) | 18.5 |
For most businesses, this means predictable tax planning and no nasty surprises as your profits grow. But there’s a crucial exception for those in the oil and gas sector.
Special Surtax for Oil & Gas Companies
If your company is engaged in the exploration and production of oil and gas, Brunei imposes a petroleum tax of 55%—a significant jump from the standard rate. This is a targeted measure, so unless you’re in this sector, you can disregard this surtax.
Case Study: How Much Will Your Company Pay?
Let’s say you’re running a digital marketing agency with a taxable profit of BND 200,000 (about $148,000 USD) in 2025. Here’s how your tax liability would look:
- Taxable Profit: BND 200,000 ($148,000 USD)
- Corporate Tax (18.5%): BND 37,000 ($27,380 USD)
No additional brackets, no hidden surcharges—just a flat calculation.
