Strategy: The Golden Ratio

1

💳 Step 1: Credit Card

Use for the first 25% of your salary. (15% deduction rate)

Since spend up to 25% is not deductible anyway, use a credit card to maximize points and airline miles.

2

💸 Step 2: Debit Card / Cash

Use for everything above 25% of your salary. (30% deduction rate)

The deduction rate is double compared to credit cards! This is where you actually save tax.

3

🚀 Step 3: Bonus Deduction (40~80%)

Traditional Markets & Public Transit qualify for 40% (up to 80%) deduction.

This is the super-deduction tier. Always use cards for transit and local markets.
