Avoid China tax residency caps your time in China at 182 days per calendar year. The statute attaches its consequence at 183 days or more, so 182 is the last safe count. Residence at 183 days in a tax year. Worldwide taxation of foreign-sourced income only bites after six consecutive such years, and a single absence of more than 30 days resets that run.
Who it applies to
This matters most if you are:
- A remote worker, digital nomad or frequent traveller spending long stretches in China.
- An expat arriving in or leaving China mid-year, where the days straddle a boundary.
- Anyone keeping a home in more than one country who needs a defensible day count for a tax return.
The rule — and why it exists
China day count. At most 182 days in China per calendar year — written as <=182 / YEAR.
Why it exists: countries use time spent as a measurable proxy for where your economic life really is. A day count gives a clear threshold; the surrounding tests stop a long holiday from making a genuine non-resident taxable.
Counting the days
- Add up every day you were physically in China between 1 January and 31 December.
- Days need not be continuous — several visits in the same year add together.
- Any day of presence generally counts, including arrival and departure days.
- The tally resets to zero on 1 January; it is not a rolling window. Reaching 183 days meets the threshold.

Examples
Example 1 — 109 days in the year
Stays: China 2026-02-01 → 2026-05-20. Checked on 2026-12-31.
Result: China day count: 73 of 182 days left (109 used in China).
Example 2 — 192 days in the year
Stays: China 2026-01-15 → 2026-07-25. Checked on 2026-12-31.
Result: China day count: over the limit — 192 of 182 days, first exceeded 2026-07-16.
Example 3 — Days split across two calendar years
Stays: China 2025-10-01 → 2025-12-31; China 2026-01-01 → 2026-04-19. Checked on 2026-12-31.
Result: China day count: 73 of 182 days left (109 used in China).
Exceptions & edge cases
- Other residency tests. Most countries also apply a domicile, home or centre-of-interests test; you can be resident under one of those with fewer days.
- Double-tax agreements. If two countries both claim you, the treaty tie-breaker (permanent home → centre of vital interests → habitual abode → nationality) decides.
- Split years. Arriving or leaving mid-year may be treated under special rules; the day count is only one input.
Common misconceptions
- "Under 182 days means I'm safe." False — other tests can apply, and the count is only one input.
- "It follows a rolling year." No — the tally resets on 1 January.
- "Arrival day doesn't count." Any part of a day inside is a day inside.
