## Do I need to pay tax if I earn less than S$22k?

If your total annual income falls below the **S$22,000 benchmark** and you receive no explicit filing notification \(e.g., SMS or letter from IRAS\), you are **entirely exempt** from filing an income tax return. 

**Important:** Even if you earn less than S$22,000, you _must_ still file if IRAS explicitly notifies you to do so.
