Corporate tax — common questions

Straight answers, current for 2025/2026.

Companies are taxed at a standard corporate rate, with concessionary rates for specific sectors and activities; the rate that applies depends on your company's business and turnover. TaxWise reads the Y/A 2025/2026 rates from a versioned tax-law database rather than hardcoding them, and shows which rate applied and why.
