Gross Income Definition and Scope
Last Updated: June 13, 2026
tips_and_updatesDefinition
Gross income refers to all income from whatever source derived by a taxpayer during a taxable year, before any deductions or exemptions, as defined under Section 32 of the National Internal Revenue Code (NIRC). It includes compensation, business income, professional income, passive income, and other sources of income subject to Philippine income tax.
Under Section 32 of the NIRC, gross income encompasses all income received by a taxpayer from any source, whether from within or outside the Philippines. This includes salaries, wages, bonuses, business profits, professional fees, rental income, dividends, interest, royalties, and capital gains. The concept serves as the starting point for computing taxable income before applying allowable deductions and exemptions. The Bureau of Internal Revenue (BIR) requires taxpayers to report all sources of gross income in their annual income tax returns, with different treatment for residents and non-residents. Gross income determination follows the all-inclusive principle, meaning all income is taxable unless specifically exempted by law.
Detailed Explanation
What Is Gross Income?
Gross income is the total of all income from whatever source derived by a taxpayer during a taxable year, before any deductions, exemptions, or allowances are applied. Under Section 32 of the National Internal Revenue Code (NIRC), gross income is the foundation upon which Philippine income tax liability is calculated. It encompasses compensation for services, business and professional income, gains from property transactions, passive income, and all other accretions to wealth not specifically exempted by law.
Sources of Gross Income
Compensation for Services
Compensation includes salaries, wages, bonuses, allowances, benefits, and other remuneration received by employees and professionals for services rendered. This covers both cash and non-cash benefits with taxable value. Under NIRC §32(a)(1), compensation is taxable regardless of the form in which it is received.
Business and Professional Income
Income derived from the operation of a trade or business, including gross receipts from sales of goods or services, is part of gross income. For professionals (doctors, lawyers, accountants, engineers), gross income includes all fees and compensation earned from professional practice. The NIRC §32(a)(2) treats business income as a primary source of gross income.
Passive Income
Passive income includes interest, dividends, rental income, royalties, and gains from the sale of property. Under NIRC §32(a)(3), income from property—whether real or personal—is taxable. This includes interest from bank deposits, bonds, and loans; dividends from stocks and mutual funds; and rental income from real property.
Other Sources
Gross income also includes prizes, awards, gifts subject to donor's tax, annuities, pensions, and any other accretion to wealth. The NIRC §32(a)(4) provides a catch-all provision for "all other income from whatever source derived" not specifically enumerated.
What Is NOT Included in Gross Income
Certain items are excluded from gross income by law. These include life insurance proceeds (NIRC §32(b)(1)), gifts and bequests (NIRC §32(b)(2)), income exempt under special laws (such as SSS and GSIS benefits under RA 8291 and RA 11199), and certain government benefits. Additionally, the NIRC §32(b) lists specific exclusions such as income derived from sources within the Philippines by non-resident foreign nationals and income from certain government securities.
Gross Income vs. Net Income
Gross income is the starting point; net income is calculated after deducting allowable expenses and deductions. For employees, the standard deduction (₱250,000 for 2024 under TRAIN Law RA 10963) is subtracted from gross compensation to arrive at taxable income. For self-employed and business taxpayers, ordinary and necessary business expenses are deducted from gross income to compute net income, which is then subject to income tax.
Importance in Tax Compliance
Accurate determination of gross income is critical because it is the base upon which all income tax calculations rest. Underreporting gross income is a common audit finding by the Bureau of Internal Revenue (BIR). Taxpayers must maintain complete records of all income sources and substantiate gross income with supporting documents such as payslips, invoices, bank statements, and financial statements.
Reporting Gross Income
Individual taxpayers report gross income on the Annual Income Tax Return (BIR Form 1700 or 1701). Self-employed and business taxpayers report gross income on their income tax returns and must file audited financial statements if gross income exceeds ₱10,000,000 (BIR Revenue Memorandum Order 15-2020). Corporations report gross income on their corporate income tax returns (BIR Form 1702).
Why it Matters
Gross income is the foundation of your tax liability in the Philippines. Understanding what counts as gross income ensures you report all required sources and claim only legitimate deductions, reducing audit risk and ensuring compliance with BIR requirements. Underreporting gross income is one of the most common violations detected in BIR audits.

Common Misconceptions
Misconception
Gross income is the same as take-home pay or net salary.
Reality
Gross income is total income before any deductions. Take-home pay is what remains after taxes and other withholdings. For a ₱600,000 salary, gross income is ₱600,000; take-home is less after income tax and other deductions (NIRC §32).
Misconception
Gifts and inheritances are always part of gross income.
Reality
Gifts and bequests are excluded from the recipient's gross income under NIRC §32(b)(2). However, the donor may owe donor's tax at 6% flat rate on gifts exceeding ₱250,000 per donee per calendar year (NIRC §99).
Misconception
Business expenses can be deducted from gross income to reduce it before reporting.
Reality
Gross income is reported as the total of all income sources. Business expenses are deducted separately to compute net income. Gross income must be reported in full; deductions are itemized separately on the tax return (NIRC §32 and §34).
Misconception
Income from informal or cash-based work does not count as gross income.
Reality
All income from whatever source derived is taxable under NIRC §32, regardless of whether it is formal, informal, or cash-based. The BIR expects taxpayers to report all income, and failure to do so is tax evasion (NIRC §32(a)(4)).
Frequently Asked Questions
Gross income is the total of all income from all sources before any deductions. Taxable income is gross income minus allowable deductions and exemptions. For employees, taxable income equals gross compensation minus the standard deduction of ₱250,000 (TRAIN Law RA 10963). For self-employed, taxable income equals gross income minus business expenses (NIRC §32 and §24).
Yes. All income from whatever source derived is taxable under NIRC §32(a)(4), including informal work, freelance projects, and side hustles. The BIR expects complete reporting of all income. Failure to report is tax evasion and subject to penalties and surcharge of 25% plus 12% annual interest (NIRC §248 and §249).
No. Gifts and bequests received are excluded from the recipient's gross income under NIRC §32(b)(2). However, the donor may owe donor's tax on gifts exceeding ₱250,000 per donee per calendar year at a flat 6% rate (NIRC §99). Inheritances are not subject to income tax on the heir; the estate may owe estate tax at 6% flat rate (NIRC §87).
List all employers and income sources on your annual income tax return (BIR Form 1700 or 1701). Include gross compensation from each employer, plus all other income (interest, dividends, rental, business, professional). The total is your gross income. Each employer withholds tax based on your gross salary; you reconcile all withholdings when you file your annual return (NIRC §32 and BIR Form 1700).
The BIR may assess additional income tax, surcharge of 25%, and interest of 12% per annum on the unpaid tax (NIRC §248 and §249). If the underreporting is willful, criminal prosecution for tax evasion is possible under NIRC §254. The BIR cross-checks gross income against third-party reports (payroll, bank interest, dividends) to detect discrepancies (BIR Revenue Memorandum Order 20-2018).
No. SSS benefits, GSIS benefits, and certain government pensions are excluded from gross income under RA 8291 and RA 11199. However, private pension income and annuities are taxable under NIRC §32(a)(3). Consult your RDO to confirm whether a specific benefit is exempt.
Report gross income as the total of all business receipts or sales before deducting expenses. File an income tax return (BIR Form 1701 or 1702) with a detailed income statement showing gross income, cost of goods sold, operating expenses, and net income. If gross income exceeds ₱10,000,000, you must file audited financial statements (BIR Revenue Memorandum Order 15-2020 and NIRC §32(a)(2)).
