Final answer:
The Mr Goh's income tax payable is $12,960.
Step-by-step explanation:
To find Mr Goh's income tax payable, we need to calculate his taxable income first. Gross tax payable for the first $120,000 is $7,950 and the tax rate for the rest is 15%.
Step 1: Calculate the total amount of income that will not be subjected to income tax: $3,000 (personal relief) + $4,000 (child relief) + $5,000 (parent relief) + $18,600 (CPF contributions) = $30,600.
Step 2: Calculate the taxable income: $185,000 - $30,600 = $154,400.
Step 3: Calculate the income tax payable for the first $120,000: $120,000 x 0.065 (tax rate) = $7,800.
Step 4: Calculate the income tax payable for the remaining income: ($154,400 - $120,000) x 0.15 (tax rate) = $5,160.
Step 5: Add the income tax payable for the first $120,000 and the remaining income: $7,800 + $5,160 = $12,960.
Therefore, Mr Goh's income tax payable is $12,960.
