Taxation Interpretation

While the US corporate tax rate stands at a seemingly straightforward 21%, the global dance of credits, deductions, and international rules reveals a complex reality where the average multinational pays just over half that rate, proving that the true art of taxation lies not in the statutory rate but in the labyrinth of provisions written beneath it.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source
ChatGPTClaudeGeminiPerplexity
