Confirm what applies to your establishment with a labour law adviser before changing registers or payroll logic. ## Content **Intro:** India consolidated 29 central labour laws into four codes. Plant HR and compliance teams still carry registers, ERP payroll references and licences named after the older Acts, so a mapping table saves a lot of searching. **Sections:** #### How to use the mapping table **Body:** Search the older Act name you know, such as Factories Act or Payment of Gratuity, and read off the new code. The third column shows where that law touches day to day plant work, so you can see which register, ERP field or licence is affected. Filter by code name to see everything one code absorbs, then export to Excel and attach it to your compliance calendar. **Bullets:** - Search by old Act name or by new code - Use the plant area column to find the affected register or process - Export to Excel and add owner and review date columns #### What the four codes cover **Body:** The Code on Wages deals with wage definition, minimum wages, payment timing and bonus. The Industrial Relations Code covers unions, standing orders, layoffs, retrenchment and dispute resolution. The Code on Social Security covers provident fund, ESI, gratuity, maternity benefit and employee compensation. The Occupational Safety, Health and Working Conditions Code covers factory licensing, working hours, safety, welfare and contract labour. A uniform wage definition under the Code on Wages affects PF, gratuity and bonus calculations together. #### Impact on ERP and payroll configuration **Body:** Wage definition is the item most likely to change payroll logic, because the codes use a common definition of wages that feeds PF, ESI, gratuity and bonus. Payroll modules in SAP, Oracle, Infor and Indian HRMS tools usually keep statutory wage components as configuration, so the change is a set of component and rule updates rather than a rebuild. Maintain the old Act reference in your documentation until your auditors and licences have moved over. #### Common mistakes **Body:** Teams assume that all older rules vanish the moment a code is notified. In practice, rules, forms and state notifications decide the effective position, and transitional provisions often keep old registers valid for a period. Another mistake is updating payroll without updating gratuity and leave encashment calculations that depend on the wage definition. Keep a dated change log for every compliance change. **Cta:** If you want payroll and compliance reports in your ERP reviewed against the new wage definition, we can help assess what needs to change, working on your own data and hardware. **Faq:** #### How many labour codes are there in India? **Answer:** There are four: the Code on Wages 2019, the Industrial Relations Code 2020, the Code on Social Security 2020 and the Occupational Safety, Health and Working Conditions Code 2020. Together they consolidate 29 central labour laws. #### Does the Factories Act still apply? **Answer:** The Factories Act is among the laws the OSH Code absorbs, but what applies to your plant today depends on notification of the code and the rules framed by the central and state governments. Check the current position with your adviser. #### Does this table replace legal advice? **Answer:** No. It is a navigation aid that maps Acts to codes at a summary level. Provisions, thresholds, forms and transition dates need to be confirmed against the official text and state rules for your establishment. #### Which code affects payroll the most? **Answer:** The Code on Wages, because its wage definition flows into PF, ESI, gratuity and bonus calculations. The Code on Social Security then governs the contributions and benefits that use those wages. ## Search terms labour codes india list of acts replaced, code on wages 2019 acts subsumed, occupational safety health code factories act, code on social security epf esi gratuity, industrial relations code 2020 acts, labour law mapping excel, old labour act to new code table, four labour codes compliance register --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
