## What’s New for EMP501 and PAYE (2026 Interim Period) South Africa’s SARS has issued key updates for the **Employer Interim Reconciliation** period, which runs from **21 September to 31 October 2026**. During this time, employers must submit the **EMP501**, reconciling all PAYE, UIF, and SDL values for the period **1 March to 31 August 2026**. Employers with fewer than 50 employees can use **eFiling**; larger employers should use **e@syFile™ Employer**. ([sars.gov.za](https://www.sars.gov.za/types-of-tax/pay-as-you-earn/?utm_source=openai)) ## Key System & Procedure Changes - **Updated e@syFile™ build** due in **mid-September 2026**, which employers must download to ensure compliance. New source codes and validations are included. ([sars.gov.za](https://www.sars.gov.za/types-of-tax/pay-as-you-earn/?utm_source=openai)) - A **new source code (ITREG)** has been introduced to help prevent **duplicate income tax registration** of employees. Employers should ensure all employee registrations are up-to-date and unique. ([sars.gov.za](https://www.sars.gov.za/types-of-tax/pay-as-you-earn/?utm_source=openai)) - Source code descriptions and validation rules have been amended—employers must accurately match payroll system codes to SARS specifications. ([sars.gov.za](https://www.sars.gov.za/types-of-tax/pay-as-you-earn/?utm_source=openai)) ## Action Steps for Employers 1. **Update payroll software** to the latest version supporting the new e@syFile™ Employer build. 2. **Audit employee tax registrations** to identify duplicates and confirm accurate tax reference numbers. 3. **Review historical payments** to ensure reconciliation values match prior EMP201 submissions. Discrepancies must be corrected. 4. **Set internal deadlines** well ahead of the closing date (31 Oct 2026), especially for payroll teams and external accountants. ## Consequences of Non-Compliance - Incorrect or incomplete EMP501s may lead to **penalties or interest**. - Wrong source codes can delay processing or trigger audits. - Failure to submit reconciliation in the correct period may affect employees’ tax certificates and promotion of trust in payroll integrity. ## Case Example - *Large payroll scenario*: A company with 200 staff must use e@syFile™ Employer. Its finance system must integrate the new ITREG code to avoid duplicate tax references across multiple departments; if not updated, the system may flag duplicates, leading to rejections or penalties. - *Small business*: Under 50 employees, filing with eFiling. Still must download updated forms and ensure payroll data aligns with new validation rules or face manual rejection or adjustment by SARS. **Bottom Line**: Don’t wait—review payroll rules now, update systems, train staff, and ensure accurate reconciliation to meet SARS’s EMP501 requirements during the interim period.
