Tax year

Formal Neutral

What it really means

The UK tax year runs from 6 April to 5 April the next year, not January to December. Allowances, tax bands and many rates reset on 6 April, so figures are often quoted per tax year.

Chinese explanation

税务年度：英国的税务年度是从 4 月 6 日到次年 4 月 5 日，而非 1 月到 12 月。免税额、税率档次和许多费率都在 4 月 6 日重置，所以数字常按税务年度来说。

Example conversation

A: Does my allowance start again in January? B: No, the tax year resets in April — everything starts fresh then.

A：我的免税额是 1 月重新开始吗？ B：不是，税务年度 4 月重置——那时一切重新计算。

What you could say back

“So the deadline dates are in April too?”
