# Where is a company's investment taxed least?

Hungary leads on effective average rate at 11.96%; Indonesia is last of the 15 shown at 21.56%.

The headline corporate rate is the number everyone quotes and almost nobody pays. OECD models a standard investment in a composite asset under each country's rate, depreciation allowances and incentives, and reports the share of its return taken in tax: the effective average tax rate. That is the figure to compare when deciding where to put a company.

Fixed interest and inflation assumptions are used so that 39 countries compare on one basis; it is a property of the tax system, not of any company's bill, and losses, sector regimes and negotiated rulings are outside it. The tool behind this page shows the statutory rate beside it and the gap between the two.

Countries OECD does not model are absent rather than estimated — the Philippines and the UAE among them. Published rates, for information only; not tax advice.
