  taxation 指整体征税制度或征税行为，是不可数名词，更正式、更抽象，通常用于讨论政策或经济议题。

Tax and taxation both relate to money paid to the government. Tax is countable, meaning the actual amount owed, often with an article and the taxed item. Taxation is uncountable, more formal, meaning the overall system of collecting taxes. Not compared: tax as a verb.

这两个词在“税收”这一意义上容易混淆，但用法有别：tax 是可数名词，指政府征收的某项具体税款，常带冠词或接具体征税对象；taxation 是不可数名词，指整体征税制度或征税行为，更正式、更抽象。这里不比较 tax 作动词“对……征税”的用法。
