关于 Internal Revenue Service (yearly average rates)

The Internal Revenue Service publishes a table of yearly average exchange rates that US taxpayers can use to convert foreign income and expenses into dollars, covering the last five calendar years. The IRS states that it has no official exchange rate and generally accepts any posted rate used consistently, so these are published averages, not official or required rates. The API serves them as foreign currency per US dollar, each dated 31 December of its year. Two punctuation slips in the IRS table are read as intended (0,924 as 0.924 and .73.686 as 73.686), and the Venezuela row is left out because its figure matches no bolívar series we could identify.

IRS 年度平均汇率有什么用途？

IRS 发布这些平均汇率，方便纳税人在美国报税时折算外币收入和费用。IRS 明确表示它没有官方汇率，并且通常接受任何一贯使用的公开汇率，因此并不要求必须使用此表。

某一项目应使用年度平均汇率，还是收付款当日的汇率，请咨询您的税务顾问。本 API 以 JSON 提供已公布的数值，便于使用和引用。
