        2. Use SRS Effectively

        Strategy:

        • Contribute maximum each year
        • Reduces current tax
        • Withdraw after 62 at lower rate

        Example: High earner

        • Current rate: 22%
        • Retirement rate: ~5%
        • Effective tax savings: 17%

        3. Claim All Reliefs

        Don't miss:

        • Parent relief (if eligible)
        • Course fees relief
        • NSman relief
        • Life insurance relief

        4. Optimize WMCR vs QCR

        Working mothers:

        • Calculate both options
        • WMCR often better for high earners
        • Can only claim one per child

        5. Time Your Income

        If possible:

        • Defer bonuses to next year
        • Accelerate deductions
        • Manage tax bracket

        Filing Your Tax Return

        For self-employed:

        • Must file by December 31 (estimated income)
        • Actual income by April 18 next year

        No-Filing Service (NFS)

        Automatic assessment:

        • If income from employment only
        • Employer filed employment income
        • No other income or reliefs to claim

        3. Missing CPF relief: Should be automatic but verify
        4. Not using SRS: Missing significant tax savings
