SARS 2026: Mandatory Tax Numbers and Enhanced Enforcement

From February 2026, PAYE reconciliations without valid Income Tax Numbers will be rejected. Plus: what SARS's technology upgrades mean for your business.

The Big Change: Mandatory Income Tax Numbers

From February 2026, employers will no longer be allowed to submit PAYE reconciliations without valid Income Tax Reference Numbers for every employee on their payroll.

SARS has been clear: "This grace period ends with the 2026 season. Reconciliations without valid Income Tax Numbers will be rejected and non-compliance will result in administrative penalties."

Who Needs Registration?

Income tax registration is required for all individuals earning above the tax threshold:

  • R95,750 per annum for individuals younger than 65 years (2026 tax year)

Action Required

  • Audit your payroll for employees without tax numbers
  • Assist employees with SARS registration
  • Update your HR systems to require tax numbers at onboarding
  • Test your payroll submission process before February
  • Enhanced Technology and Enforcement

    SARS has announced significant system modernisations for 2026, including:

    Data Analytics and AI

    • Improved detection of non-compliance
    • More rigorous audits
    • Enhanced collection of outstanding taxes

    Third-Party Data Verification

    Greater emphasis on proactive verification of:
    • Retirement fund withdrawals
    • Investment income
    • International transactions
    • Bank account transactions
    SARS says: "In 2026, taxpayers can expect SARS to continue strengthening its enforcement, verification and compliance activities, supported by increasingly sophisticated technology."

    The Tax Gap

    SARS is attempting to close a tax gap estimated at nearly R500 billion. For businesses, this means:

    • Expect more queries and audits
    • Maintain meticulous records
    • Ensure all income is properly declared

    Key Dates for 2026

    New ITR12 Features

    Updates to the individual tax return include:

    • New source codes 3623 and 3673 for backdated salaries and pensions
    • Source codes 4306 and 4307 for local and foreign dividends
    • Automatic carry-forward of unused foreign tax credits (up to 6 years)
    • Separate wizard questionnaires for residents vs non-residents

    Large Business Forum

    SARS has launched the Large Business Forum focusing on "key taxpayers" across sectors. The large and international business segment contributed R600 billion in taxes in 2024-2025—expect continued scrutiny here.

    Practical Steps

  • Register all employees for income tax before February 2026
  • Review your record-keeping for audit readiness
  • Reconcile third-party data (banks, retirement funds) with your submissions
  • Separate business and personal finances clearly
  • Consider professional tax planning given tighter enforcement
