How the bonus tax trap zones work

What are bonus "tax trap zones"?

Under separate bonus taxation, brackets jump at thresholds — certain bonus amounts trigger "one yuan more, thousands more tax." These are the trap zones (the bonus trap).

Which amounts are common trap zones?

The classic trap is CNY 36,001 – 38,566. A CNY 36,000 bonus pays CNY 1,080 tax, netting 34,920; at CNY 36,001, the 10% bracket kicks in, tax jumps to 3,495 and you net only 32,505! One extra yuan of generosity costs you over CNY 2,400.

What if you fall into a trap zone?

This tool flags trap zones automatically. If you're in one, negotiate with finance or HR to move the excess — paid out together with that month's base salary — so the bonus sits exactly at the prior bracket's ceiling (e.g. CNY 36,000 or 144,000 on the nose), maximizing what you keep.

Frequently Asked Questions

How is an annual bonus taxed?

The annual bonus can be taxed separately or merged with salary — the choice can swing your tax by thousands. This calculator compares both automatically.

Why do trap zones exist?

Separate taxation uses the monthly schedule: crossing a bracket with just 1 more yuan can cut net pay by over a thousand — the famous trap zone.

What bonus amount is most tax-efficient?

Scanning CNY 0–500K reveals the local peaks of the net-income curve — those are the optimal payout amounts.

Is it better to combine or separate the bonus from salary?

It depends on the salary level. This calculator shows both methods side by side and picks the one that maximizes take-home.
