## Trusts: What’s New in Legal Changes & Reporting

- Trigger-change in section 7(5): When a donor ceases to be a South African tax resident, deemed income accrual ends from that date. Applies to years of assessment starting on or after 1 March 2026. ([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/trusts/trust-legal-changes/?utm_source=openai))
- Section 18(2B) now clarifies deduction rules for donations to certain organisations. Trustees and taxpayers must ensure that charities or organisations qualify before claiming. ([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/trusts/trust-legal-changes/?utm_source=openai))
## EMP501 and Employer Requirements
- Employers must use the updated **Business Requirements Specification** v25.3.0 for EMP501 submission. Ensure payroll systems reflect updated source codes (notably ITREG) to avoid duplicate employee registrations. ([sars.gov.za](https://www.sars.gov.za/latest-news/employer-interim-declarations-emp501-21-september-to-october-2026/?utm_source=openai))
- Valid employee Income Tax numbers are now strictly enforced: missing or invalid references can lead to rejections. ([sars.gov.za](https://www.sars.gov.za/latest-news/employer-interim-declarations-emp501-21-september-to-october-2026/?utm_source=openai))
## Actionable Tips for Individuals & Trustees
- Check your auto-assessment status early using SARS Online Query System to know whether you need to file. reduces surprises. ([sars.gov.za](https://www.sars.gov.za/latest-news/everything-you-need-to-know-about-auto-assessments/?utm_source=openai))
- If you’re changing residence or considering emigrating, track dates to determine when certain deemed income triggers apply (section 7(5)) and whether losses can be ring fenced under the new rate. ([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/trusts/trust-legal-changes/?utm_source=openai))
- Trustees should gather crucial documents in advance: trust deed, income-expenditure sheets, beneficial-ownership documentation, resolutions, financial statements. ([sars.gov.za](https://www.sars.gov.za/latest-news/media-release-trust-filing-season-set-to-open/?utm_source=openai))
## Why It Matters
These changes aren’t just administrative—they can affect:
-****■■**tax payable**■■ (loss ring fencing under lower marginal rates may reduce tax burden)
-****■■**liability and timing for trusts**■■ (deemed accrual, representation definitions)
-****■■**penalties**■■ for late or incorrect submissions—EMP501 deadlines, trust registrations, or trustee obligations carry legal risk. ■•
Staying informed and pro-active will help avoid costly errors and leverage benefits. SARS’ recent updates show a trend toward clarity, automation, and stricter enforcement—you’ll want to stay ahead.
