What is income tax?
An income tax is a tax charged on individuals or entities that varies with their respective income or profits. Many jurisdictions refer to income tax on business entities as company’s tax or corporate tax. Partnerships generally are not taxed; rather, the partners are taxed on their share of partnership items. Taxes imposed at the national level are collected by the Bureau of Internal Revenue (BIR), while those imposed at the local level such as provincial, city, municipal, barangay are collected by a local treasurer’s office.

Taxation – is the most influential and powerful in the government, without taxation our government will not survive because taxes is the strength or they call it the lifeblood of the government. It is the imposition of financial charges or other levies upon taxpayer by a state such that failure to pay is punishable by law.

These are the basic types of taxation:

1. Personal Income Tax – charge on incomes of individuals, households, partnerships and sole proprietorships

Computation of Income Tax
Here is an example of computation of an Income tax;
Mr. X is a well-paid employed as a full time Professor at the Philippine Women’s University. His Monthly salary is P85, 000. Deducted 32% of his salary for tax. He is married, with 5 children namely, Juan, 30 years old but mentally retarded, Tudis, 25 years old, third, 20 years old, fourth, 18 years old and fifth is 15 years old. To solve the monthly and annual tax of Professor X we need to identify first if there is an overpayment/tax payable using the following allowable deductions:

SSS 700 monthly
Phil health 200 monthly
Pag ibig 200 monthly
Union 100 monthly
Total allowance Reduction P1,200/month X 12 = P14,400/ year
Gross Income P75,000 X 12 = P900,000/ year
Tax Deduction from his employer (32% of his salary) P900,000 X.32 = P288,000
Tax Income P75,000 – P1,200 (allowance deduction) = 73,800
Annual Tax of Professor X P73,800 x 0.32 = P23,616 monthly tax X 12 = P283,392
Mr. Magnifico is gainfully employed as a National sales manager in a Pharmaceutical company. His salary is P85, 000 and the said company deducted 32% of his salary for tax. He is Single, with no dependent. Solve the monthly and annual tax of Mr. Magnifico. Identify if there is an overpayment/tax payable using the following allowable deductions:

SSS 700 monthly
Phil health 200 monthly
Pag ibig 200 monthly
Union 100 monthly
Gross Income P1,020,000 – P14,400 (allowance deductions) = 1,005,600
Gross Taxable Income P1,005,600 – 50,000 (personal exemptions) = P955,600
Taxable Income (Notes: using the tax table tax due is P125,000 + 32% of the excess of P500,000 P955,600 – P500,000 = P455,600 X 0.32 = P145,792 + P125,000 = P270,792
Tax due from his employer P326,400
Tax withheld per BIR 1700 P270,792.00
Computation: Overpayment of Mr. Magnifico from his employer P55,608.00 (Refundable)


The main purpose of taxation is to accumulate funds for the functioning of the government machineries. No government in the world can run its administrative office without funds and it has no such system incorporated in itself to generate profit from its functioning. The government’s ability to serve the people depends upon the taxes that are collected. Taxes are indispensable in the government operation and without it the government will be paralyzed.
