The Provision for Income Tax is the amount of money a company expects to pay in taxes during the current year. To calculate this, adjustments are made to the company’s net income, accounting for temporary and permanent differences, and then this figure is multiplied by the applicable tax rate.

A tax provision represents the amount a company expects to owe in income tax to the IRS for the current year. It’s just one piece of the puzzle in the financial planning of a business. Corporate finance departments also set aside provisions for other foreseeable expenses such as bad debts, depreciation, product warranties, pensions, and sales allowances.

In the world of accounting, tax provisions are classified as current tax liabilities. This categorization is due to these funds being designated for taxes expected to be paid within the current year. However, the process of calculating tax provisions isn’t as straightforward as it may seem. Striking the right balance between efficiency, accuracy, and defensibility can be quite a challenge. Estimating the tax provision for each year demands a substantial amount of time and effort from corporate tax departments.

Here’s How We Calculate the Provision for Income Tax

A company’s tax provision can be broken down into two main components: current income tax expense and deferred income tax expense. However, things get a bit tricky because most accounting departments follow Generally Accepted Accounting Principles (GAAP) to determine their financial status. GAAP procedures have their unique nuances compared to income tax accounting rules, and these distinctions significantly influence how current and deferred income tax expenses are computed.

Provision for Income Tax Formula = Income Earned Before Tax * Applicable Tax Rate

Key Points to Remember:

  • The company creates the provision from its current profits to cover future tax obligations.
  • It considers the applicable tax rate for the given period.
  • The provision is established by accounting for differences in the company’s net income, both permanent and temporary.
  • There’s typically a time gap between when the provision is created and when it’s paid. During this interim period, the company can use it as a source of short-term financing.

Example of Calculating the Provision for Income Tax:

Certainly, let’s break down the concept of Provision for Income Tax with an example:

Imagine Company XYZ, which operates in the field of technology, recently concluded its financial year on December 31, 2022. The prevailing income tax rate for the year is 25%. Let’s calculate the profit before tax based on the provided financial details and determine the required income tax provision.

Here are the financial figures for Company XYZ:

  • Total Sales: $3,000,000
  • Cost of Goods Sold: $1,800,000
  • Administrative Expenses: $500,000
  • Distribution Expenses: $200,000
  • Interest Expense: $120,000
  • Rental Income: $50,000

Step 1: Calculate Profit Before Tax

To calculate the profit before tax, we need to sum up the relevant figures:

  • Profit Before Tax = (Total Sales – Cost of Goods Sold) – (Administrative Expenses + Distribution Expenses + Interest Expense – Rental Income)
  • Profit Before Tax = ($3,000,000 – $1,800,000) – ($500,000 + $200,000 + $120,000 – $50,000)
  • Profit Before Tax = $1,200,000 – $770,000
  • Profit Before Tax = $430,000

So, Company XYZ’s profit before tax for the financial year ending December 31, 2022, is $430,000.

Step 2: Calculate the Provision for Income Tax

Now, let’s determine the provision for income tax by applying the tax rate:

  • Provision for Income Tax = Profit Before Tax * Tax Rate
  • Provision for Income Tax = $430,000 * 25%
  • Provision for Income Tax = $107,500

Therefore, Company XYZ should make a provision for income tax amounting to $107,500 for the financial year ending December 31, 2022. This ensures that they are prepared to meet their tax obligations when they become due, considering the applicable tax rate.

Advantages and Disadvantages of this Provision:


  1. Short-Term Financing: The company sets aside this provision from its current profits to meet its future tax obligations. There’s often a time gap between when the provision is made and when it’s paid. During this period, the company can use this provision as a source of short-term finance. This doesn’t involve any extra costs or legal formalities.
  2. Future Liability Awareness: By creating the provision for income tax, the company prepares in advance for its future tax liabilities. This awareness benefits all stakeholders by ensuring they know about the impending tax obligations.


  1. Short-Term Use: This provision serves as a source of short-term financing and can’t be used to meet long-term financial needs.
  2. Excess Provision: Sometimes, companies may overestimate the provision for income tax, resulting in underutilized funds. These funds could have been put to more productive use in other areas.

How Do You Go About Calculating a Tax Provision?

Getting an accurate handle on the precise amount of income tax you owe can be a time-consuming endeavor. This is where having accounting experts in your corner can be a real asset, freeing you up to concentrate on expanding your business.

However, it’s still a wise move to have a basic understanding of tax provisions when you’re at the helm of a business. So, let’s simplify the process of computing corporate tax provisions under Accounting Standards Codification (ASC) 740. ASC 740 outlines the guidelines for how companies should recognize income tax in their financial statements.

Current Income Tax Expense

The current tax expense is the amount a company expects to pay in taxes for the present year. To calculate this, we consider the company’s current earnings and the differences between Generally Accepted Accounting Principles (GAAP) and income tax rules for the current year. Here’s a simplified breakdown of how we arrive at the current income tax provision:

  1. Start with Net Income: Begin with the company’s net income, which is its income before income taxes, calculated according to GAAP.
  2. Identify Permanent Differences: These are income or expenses not allowed for income tax purposes but permitted under GAAP. Permanent differences, like fines, entertainment expenses, municipal bond interest, and life insurance proceeds, remain constant.
  3. Recognize Temporary Differences: Temporary differences are income or expenses allowed under either GAAP or income tax rules in one year but not in the other. We find these by comparing the current year’s balance sheet against GAAP and tax calculations. Common examples include unpaid expenses and depreciation.
  4. Apply Credits and Net Operating Losses (NOL): After considering these differences, we determine the current year taxable income. We can then apply any tax credits and Net Operating Losses (NOL).
  5. Apply the Current Tax Rate: Multiply the current year taxable income by the prevailing federal tax rate to calculate the company’s current year tax expense for the income tax provision.

Deferred Income Tax Expense

Deferred income tax is a liability on the balance sheet that isn’t due for payment yet. This aspect of the income tax provision calculates a cumulative total of temporary differences and applies the relevant tax rate. It focuses on the deferred effects of income, expenses, NOL, and tax credits. Once calculated, the deferred tax expense is recorded on the company’s balance sheet as an asset or liability, depending on whether it anticipates owing taxes or receiving a tax benefit in the future.

Challenges in Calculating the Income Tax Provision

Calculating the tax provision is intricate and comes with its set of challenges. Tax teams often encounter these common calculation issues:

  1. Timing Mismatch in Income Reporting: Accurate calculations rely on starting with the correct net income figure, which can be challenging when companies report income annually or quarterly.
  2. Data Collection and Integration: Gathering and integrating data from finance and tax departments, and ensuring its proper structuring, can be complex.
  3. Managing a High Volume of Data: Even straightforward calculations require tax experts to scrutinize items like annual reports, financial statements, tax payments, and net income.
  4. Adapting to Tax Law Changes: Changes in tax laws can impact calculation formulas, necessitating a constant awareness of new regulatory requirements.
  5. Over-Reliance on Manual Processes: Using spreadsheets and manual processes to calculate the corporate tax provision can slow down the process and increase the risk of inaccuracies.

Steps to Improve the Tax Provision Calculation

To enhance tax provision calculations and results, consider the following steps:

  1. Data Management: Efficiently collect and analyze data to improve the accuracy of tax provision calculations.
  2. Use Tax Provision Checklists: Tools like the Thomson Reuters Corporate Income Tax Provision Checklists can help assess income tax measurement processes, disclosure requirements, and risk management controls.
  3. Review Compliance: Thoroughly examine the tax provision calculation process to ensure the correct criteria are applied.
  4. Automation: Implement tax provisioning solutions that automate data collection, consolidation, and analysis, reducing laborious tasks and enhancing accuracy.

In conclusion, Provision for Income Tax is a vital financial measure companies use to prepare for their tax obligations.

This provision serves as a short-term financial source during the gap between its creation and payment, enabling companies to manage their tax liabilities efficiently. However, it’s important to note that this provision is suitable for short-term financial needs and not for long-term financing. Companies should also be cautious about overestimating this provision, as it can lead to underutilization of their funds.
