What Is Ordinary Business Income and How Is It Reported?

Ordinary business income is a fundamental concept in accounting and taxation, representing the net earnings derived from regular business operations. Understanding how this income is reported is crucial for businesses and individuals, as it impacts tax liabilities and financial planning.

Types of Earnings Included

Ordinary business income includes earnings from core business operations, primarily generated through the sale of goods or services. For example, a retail store earns income by selling merchandise, while a consulting firm generates revenue through service fees. The Internal Revenue Code (IRC) Section 61(a) broadly defines gross income, encompassing all income from any source unless specifically excluded by law.

In addition to direct sales, ordinary business income also encompasses operational revenues like rental income from business property, interest from business bank accounts, and royalties from intellectual property. These sources, though not directly tied to primary business activities, contribute to a company’s financial health. For instance, a tech company earning royalties from licensing its software would classify these earnings as part of ordinary business income. To qualify, such income must be regular and recurring, distinguishing it from extraordinary or one-time gains.

Allocation in Pass-Through Structures

Pass-through structures, including S corporations, partnerships, and LLCs, allow income to bypass taxation at the corporate level, instead being reported by individual owners or partners on their personal tax returns. Allocation rules ensure fair distribution among stakeholders.

For partnerships, allocation is often detailed in the partnership agreement, which may specify pro-rata distribution based on ownership percentages or special allocations reflecting partners’ contributions and roles. S corporations, however, allocate income strictly in proportion to share ownership, as required by the IRS.

The Tax Cuts and Jobs Act (TCJA) introduced the Qualified Business Income (QBI) deduction, enabling eligible taxpayers to deduct up to 20% of their qualified business income from pass-through entities. This deduction is subject to limitations, such as taxable income caps and restrictions for specified service trades or businesses (SSTBs). For instance, the deduction begins phasing out for single filers with taxable income above $182,100 and joint filers above $364,200 in 2024.

Adjustments for Tax Purposes

Reporting ordinary business income for tax purposes often requires adjustments to align with tax regulations. Depreciation, as outlined in IRC Section 167, allows businesses to deduct a portion of an asset’s cost over its useful life, reducing taxable income. The Modified Accelerated Cost Recovery System (MACRS) is commonly used for this purpose, permitting accelerated write-offs.

Business expenses must be ordinary and necessary under IRC Section 162 to qualify for deductions, including costs like salaries, rent, and utilities. Certain expenses, such as meals and entertainment, are subject to limitations, with only 50% typically deductible. Businesses should also account for Net Operating Loss (NOL) provisions, which allow losses to be carried forward to offset future taxable income, as specified in IRC Section 172. Starting in 2024, NOLs can be carried forward indefinitely but are limited to 80% of taxable income in any given year.

Tax credits, like the Research and Development (R&D) credit or the Work Opportunity Tax Credit (WOTC), provide dollar-for-dollar reductions in tax liability and incentivize innovation or hiring from targeted groups. Careful documentation is essential to fully leverage these credits.

Reporting on Individual Returns

Individuals receiving ordinary business income from pass-through entities must accurately report this income on personal tax returns. The entity issues a Schedule K-1 to each owner, detailing their share of income, deductions, and credits. This information is then used to complete Schedule E (Supplemental Income and Loss) on Form 1040, where income or losses from partnerships, S corporations, estates, and trusts are reported.

Ordinary business income also affects Adjusted Gross Income (AGI), which influences eligibility for various credits and deductions. For instance, a higher AGI can limit contributions to a Roth IRA or phase out eligibility for the American Opportunity Tax Credit. Strategic planning around reporting ordinary business income is key to optimizing tax outcomes.

Exclusions or Non-Deductible Items

Certain revenues and expenses are excluded from ordinary business income or deemed non-deductible, as outlined by tax regulations. These exclusions can significantly affect taxable income calculations.

Income exempt from federal taxation, such as municipal bond interest, is excluded from ordinary business income, even if earned through business operations. Similarly, life insurance proceeds received upon the death of an insured individual are generally excluded under IRC Section 101(a).

On the expense side, specific costs are non-deductible regardless of their connection to business operations. Fines and penalties paid to government agencies for regulatory violations cannot be deducted, as stated in IRC Section 162(f). Expenses related to lobbying or political contributions are also non-deductible. Additionally, IRC Section 162(m) limits the deductible amount of executive compensation for publicly traded companies to $1 million per covered employee, with exceptions for certain performance-based compensation plans. Businesses must thoroughly review financial records to identify and segregate non-deductible items to ensure accurate tax reporting.
