Under current national law, a married couple in China can have up to three children. That limit took effect on August 20, 2021, when the top legislature amended the Population and Family Planning Law, replacing the two-child rule that had been in place since 2016. Some provinces have gone further and removed birth registration caps altogether, so how many kids you can have in China depends partly on where you live, but three is the national baseline for everyone.
How the Limit Reached Three
The one-child policy began in 1979 under Deng Xiaoping, restricting most Han Chinese couples to a single child and penalizing families that exceeded the quota with “social maintenance fees” that could run several times a household’s annual income. By 2016, lawmakers amended the Population and Family Planning Law to allow two children. Birth rates barely responded. In May 2021 the central government announced a further expansion, and the legislature formalized the three-child limit that August, at the same time abolishing the social maintenance fee system and directing provinces to roll out family support measures.
The demographic picture explains the urgency. China’s mainland population fell to roughly 1.408 billion by the end of 2024, down about 1.39 million from the prior year and marking the third consecutive year of decline.1Gov.cn. China’s Population Declines in 2024 The fertility rate has dropped to roughly one birth per woman, well below the 2.1 replacement level.
Provinces That Go Beyond Three
Three is a floor, not necessarily a ceiling. Individual provinces have latitude to loosen the rules further, and some have.
The clearest example is Sichuan, a province of more than 80 million people, which in early 2023 removed all caps on the number of birth registrations for any parent. Sichuan also began allowing unmarried individuals to register births, a sharp departure from longstanding practice. The province framed the change as a shift from controlling births to responding to what people actually want.
Ethnic minorities historically received more lenient treatment under family planning rules, generally allowed two or three children during the one-child era depending on the region. With the national limit now at three for everyone, that distinction matters less in practice, though some autonomous regions keep their own local rules.
If you live somewhere that has loosened restrictions past the national baseline, local rules control. Checking with the local health commission or family planning office before assuming a hard cap applies is worth the effort.
What Happens If You Have More Than Three
For decades, the social maintenance fee was the main enforcement tool. Fines were calculated as multiples of local per-capita income and could run from three to six times annual income for a second child, and fifteen times or more for additional children, depending on the jurisdiction. Wealthy families in some provinces faced fines pegged to their own earnings.
The 2021 amendment abolished those fees nationwide, and the State Council followed in September 2021 by annulling the administrative regulations that governed their collection.2Gov.cn.

The consequences haven’t vanished entirely, though. Communist Party members and government employees have historically faced internal disciplinary sanctions for exceeding birth limits, and the amended law still references “disciplinary sanctions” without clearly defining their scope. Provincial rules that once required firing private-sector workers for policy violations have been repealed, but internal Party discipline operates on its own track. For ordinary citizens outside the government and Party apparatus, having a fourth or fifth child today carries no meaningful legal penalty in most of the country.
One Boundary Worth Knowing
The relaxed limits and the loosening in places like Sichuan mostly address the birth cap itself. Registering a child in the household registration (hukou) system without a marriage certificate is a separate question, and implementation remains uneven. Some local offices still expect a marriage certificate in the standard document package, and unmarried parents may face additional requirements such as a paternity test or a community police report. The number of children you may have is one issue; getting each of them registered is another, and the two don’t always move in step.
Government Support for Larger Families
China has flipped from penalizing large families to subsidizing them, though the amounts are modest compared to the cost of raising children in Chinese cities.
Parents can deduct 2,000 yuan (roughly $280) per month per child from their taxable income for children under three, and the same amount for children’s educational expenses from age three through graduate school. That deduction was doubled from 1,000 yuan in January 2023.3Gov.cn. China Adjusts Additional Deduction Standards in Personal Income Tax
A nationwide childcare subsidy program provides 3,600 yuan (about $500) per year for each child under three. The subsidy is exempt from income tax and does not count against eligibility for poverty-related assistance programs.4Gov.cn. China to Offer Nationwide Childcare Subsidies The government has also announced plans to make childbirth essentially free under the national medical insurance system, covering hospital delivery costs that parents previously paid out of pocket.
Provinces and cities layer their own incentives on top. Some offer one-time birth bonuses, monthly stipends for second and third children, or housing subsidies for larger families. Maternity leave, at a national baseline of 98 days, runs longer in every province, with 158 days common and some provinces reaching 178 to 188 days or, in Tibet, up to a full year. Several provinces grant extra days specifically for a second or third child.5National Health Commission of the People’s Republic of China.

The specifics vary widely by location, so the local government is the only reliable source for exactly what you qualify for where you live.
