If you're working in China and earning foreign income, the 183-day rule matters. A lot.
Basically: stay in China more than 183 days in a calendar year and you might owe Chinese income tax on your worldwide income. Not just your China salary. ALL of it.
How I track it:
I have a spreadsheet. I know, exciting.
Column A: Date
Column B: Location (China / Not China)
Column C: Running total of China days
Every time I travel, I update it. When I hit 150 days, I start getting nervous. At 170, I plan my exit.
What counts as "in China":
• Any day you're physically in mainland China
• Does NOT include Hong Kong, Macau, Taiwan (they count as outside China for tax)
• Partial days count as full days (land at 11:59 PM? That's a China day)
The loophole:
The 183 days is per CALENDAR YEAR (Jan 1 – Dec 31). So if you arrive in July and leave in June, you could theoretically stay 365 days but split across two calendar years = 0 tax years.
What I actually do:
I aim for ~160 days max per year. Gives me buffer. I travel to HK or elsewhere for long weekends. Keeps me under the limit and gives me a break from the mainland internet.
Disclaimer: I'm not an accountant. Talk to a real tax advisor. But track your days. The government definitely is.
How do you handle the 183-day thing? Or do you just... not think about it?
