Many people treat social insurance as a benefit the company hands out, something to be negotiated: take it as cash instead, or sign a statement saying you give it up voluntarily. A new official document, effective November 1, closes that door.
The document is the 2026 edition of the national tax administrative penalty discretion standards, issued under State Taxation Administration Announcement No. 20 of 2026. It was published on September 28 and takes effect on November 1. One clause in it concerns almost every employee in the country: for the first time, violations in the payment of social insurance premiums have been folded into the nationwide, unified tax penalty framework. They sit at item 30, under the category of violations in the collection and administration of taxes and fees.
1. The fines: one to three times, but not for a first missed payment
Item 30 states that an employer which fails to pay, or underpays, social insurance premiums within the prescribed period, and still does not pay after the tax authority orders payment within a deadline, faces a fine of one to three times the amount owed.
The fine is tiered by the amount owed and its share of the total due. Underpayments below 500,000 yuan, or between 500,000 and 5 million yuan but accounting for less than 30 percent of what should have been paid, draw a fine of one times the amount owed. Underpayments between 500,000 and 5 million yuan at 30 percent or more, or above 5 million yuan at under 30 percent, draw one to two times. Above 5 million yuan at 30 percent or more, or in other serious cases, the fine is two to three times the amount owed.
A late fee of 0.05 percent per day is added from the date the payment fell due.
The order to pay within a deadline comes first. Only continued non-payment after that triggers a penalty.
2. The rule is not new. The yardstick is
The one-to-three-times fine did not appear this time.
Shi Zhengwen, director of the Fiscal and Tax Law Research Center at China University of Political Science and Law, explains that the penalty was already set out in the Social Insurance Law, in force since 2011. What changed is the uniformity of enforcement: when the fine is one times and when it is three times now follows a single national standard.
The background is that tax authorities in six major regions—Northeast, Southwest, Northwest, Central South, North and East China—had each issued their own regional discretion standards. This document gathers that practice into one national version.
3. Why a “voluntary waiver” does not hold
What most people actually run into is this: the employer asks them to sign a statement waiving social insurance, sometimes promising to pay the equivalent as cash.
The Labor Law and the Social Insurance Law make contributions a compulsory obligation for both employer and employee. In Shi’s words, the agreement is void because it violates mandatory provisions of law.
4. The arithmetic of taking social insurance as cash
Converting contributions into cash looks like more money in hand in the short term. Chu Fuling, director of the Social Security Research Center at the Central University of Finance and Economics, has run the numbers.
Suppose the contributory wage is 10,000 yuan but contributions are paid on 5,000. When the pension is calculated, the base is halved, and the pension level drops with it. Work injury and maternity benefits are also usually calculated on the contributory wage.
The other side of that ledger comes due in the year the pension is drawn.
5. When the numbers on your record look wrong
First, preserve evidence: keep payslips, bank statements and the employment contract, and note the gap between actual wages and the contribution base.
Then ask for back payment in writing, submitting a written request that the employer pay the difference as required by law.
If negotiation fails, complain to the social insurance collection agency—the tax authority—or to the labor security supervision team.
Article 6 of Announcement No. 20 addresses which rules apply across the effective date: for violations that occurred before the announcement took effect and for which no penalty decision has yet been made, the rules in force at the time of the violation apply, unless applying this announcement benefits the taxpayer or fee payer. Back-payment procedures and complaint channels vary by locality; local tax authorities and social insurance agencies have the final word.
