Deferred Income Tax

A tax liability that is directly related to differences in income recognition between tax laws (IRS) and accounting methods (GAAP)

What is a Deferred Income Tax?

Deferred income tax is a liability that can be found on a balance sheet. It results from differences in income tax recognition between tax laws (IRS) and accounting methods (GAAP).

 

Deferred Income Tax

 

In financial reporting, a company’s income tax payable must equate to total tax expense. However, income tax payable may not equal total tax expense due to the difference in income recognition between tax laws and accounting methods.

To simplify, accounting rule differences between a company and the IRS may cause a deferment in income tax payment.

 

Summary

  • Deferred income tax is a liability. It primarily arises from differences in taxes payable created by different depreciation methods.
  • It is directly related to differences in income recognition between tax laws (IRS) and accounting methods (GAAP).
  • The IRS follows the MACRS depreciation system that includes the straight-line method and the declining balance method.
  • Accountants not using the MACRS depreciation system may run into income tax treatment issues causing income tax to be deferred.

 

The IRS vs. GAAP

The Internal Revenue Services (IRS) is a government agency primarily responsible for collecting taxes and administering statutory tax laws. Generally Accepted Accounting Principles (GAAP) regularly follows a set of accounting rules and principles that govern the standards for year-end financial reporting.

Consequently, the rules and principles within GAAP can sometimes differ from the rules and principles within the IRS. Such rule differences can cause differences in calculations and the postponement of income tax payments.

For example, the most common difference between the IRS and GAAP is the methods used to calculate depreciation.

Deferred income tax is mainly caused by differences in income recognition between tax laws (IRS) and accounting methods (GAAP). Listed below are the main characteristics of the IRS and GAAP to better understand how different they are.

 

IRS:

  • Responsible for tax return processing
  • Provide taxpayer services to individuals and  companies
  • Conducts audits and investigations and ensures taxation enforcement
  • A company is more likely to be audited by the IRS if it is a complex business

GAAP:

  • Accounting rules and principles
  • Accountants follow GAAP when they prepare financial statements
  • Public companies must follow GAAP rules and principles
  • The primary focus is to ensure consistency, clarity, and comparability of financial statements issued by companies and individuals

Treatment of Depreciation (IRS vs. GAAP)

The main cause of deferred income tax is due to the differences between how depreciation is calculated under the IRS and GAAP.

  • IRS: The IRS allows a set list of depreciation methods for the treatment of depreciation on specific assets. It can cause reporting discrepancies when accountants choose to use alternate depreciation policies that are different from the tax agency.
  • GAAP: Unlike the IRS, GAAP gives accountants the freedom to select from multiple methods of depreciation. With this in mind, freedom in selection can potentially cause a wide variety of differences between the IRS and GAAP.

 

As a whole, accountants will follow GAAP to prepare financial statements, calculate taxes payable separately, and take advantage of any rules to reduce taxes payable. These motivations can cause depreciation to be stated differently when tax season arrives.

 

MACRS – The IRS’s Depreciation System

Some of the methods used for depreciation by the IRS are discussed below.

The modified accelerated cost recovery system (MACRS) is the primary tax depreciation system used by the IRS. It allows the capital cost of an asset to be recovered through annual deductions over a certain period. Also, the IRS has a specific list of assets that are eligible for MACRS depreciation and assets that are not.

For example, MACRS depreciation can be used on assets, such as office furniture, buildings, and equipment. It cannot be used on intangible property, certain aged properties, and film/video recording.

Within the MACRS system, two distinct forms of depreciation are used – the straight-line and declining balance methods.

The IRS’s depreciation system limits accountants to two basic methods of depreciation. GAAP uses the two forms of depreciation stated above, but it also adds methods such as the sum of the year’s digits method and the units of production method.

As you can envision, deferred income tax arises when accountants use different depreciation methods other than the straight-line method and the declining balance method.
