Effective tax rate

July 27, 2023
The average amount of tax an individual or business has to pay is its effective tax rate. A person's taxable federal income tax is the tax due on their income before deducting any state, local, or FICA taxes. To calculate an enterprise's effective tax rate, divide its tax bill by its profit before taxes. Individuals' effective tax rates are calculated by dividing their total tax liabilities by their taxable income. In a system where tax obligations are applied to individuals based on their actual taxable earnings, the marginal tax rate is the highest proportion of income tax each individual must pay.

What is the effective tax rate?

A company or individual's effective tax rate is the average rate of taxation for which they are responsible. The effective tax rate is a typical rate at which a person's generated and unearned revenue is taxed.

Salary, wage, and dividends are all examples of earned income, whereas interest and capital gains are unearned. A company's effective tax rate is the standard rate at which it pays taxes on its profits. However, the legal percentage of the statutory tax rate is established by statute.

It is the percentage of taxable income subject to federal income tax after subtracting any applicable state, local, or FICA taxes. The marginal tax rate is one possible equivalent of the effective tax rate. Nonetheless, the two rates are not the same. When analyzing the tax burdens of two entities or individuals, the effective tax rate is a helpful metric.

The concept of effective tax rate

A taxpayer's effective tax rate is the sum of their annual tax bill and taxable income. Approximately 95% of Americans supposedly benefit more from the United States' effective tax rate brackets, which take into account each taxpayer's last dollar of income. However, those in higher tax categories may find the marginal tax rate more manageable.

An effective tax rate is one statistic that investors may use to gauge the viability of a business. Thus familiarity with the idea is crucial. However, the rate may change drastically yearly under a progressive tax scheme as various taxable income levels are taxed at different rates. Without such context, it is hard to determine what led to an unexpected increase or decrease in the tax rate. For instance, the corporation may have manipulated its asset accounting to lower its tax rate. Nonetheless, the tax rate is representative of the total tax levy.

Taxpayers often use tax tables to estimate their tax bills. However, these tables are often missing key details. Firstly, effective tax rates are a weighted average of all the rates in a tax table. Federal income tax obligation for a person may be calculated using the 10%, 15%, or 18% tax brackets. The average of these rates will be determined based on the taxpayer's effective tax rate.

Furthermore, effective tax rates reflect tax laws that provide incentives and may decrease taxable income. A business or person may want to compare their reported taxable income to the amount of tax they paid. This data might be particularly useful when comparing the tax efficiency of competing businesses or weighing the pros and cons of relocating to a state with more onerous personal tax requirements.

The progressive Federal tax structure allows for an effective rate for people in the United States. Varying tax rates apply to varying amounts of taxable income for individuals and businesses. The marginal tax rate rises with each additional dollar of taxable income. A weighted average rate does not equal the sum of the bracket rates because individual rates fluctuate.

Financial statements and taxation rates

The financial stability of an organization may be quickly assessed by reviewing its income statement, which provides a snapshot of the business's financial performance over a certain period (often one year or four quarters). Cost of goods sold (COGS), gross margin, cost of goods sold (COGS), gross margin, sales revenue, operating expenditures, x tax expense, and net income are all items that may be seen on an income statement. The financial viability of a business may primarily be ascertained via the income statement.

Along with calculating net income, a corporation will typically provide net income before taxes. Earnings Before Interest and Taxes (EBIT) refers to this figure, often not including debt servicing costs. Taxes are paid on taxable income, then subtracted to get to net income when interest is factored out.

The income statement does not disclose a corporation's effective tax rate. In either case, the remainder of the data on the income statement may be used to calculate the effective tax rate.

Computation of the effective tax rate

The effective tax rate is the effective rate of taxation that the firm incurs on its profits. Divide your income tax bill by your pre-tax income for the easiest approach to get your effective tax rate. Tax cost is often shown immediately before the net income total on an income statement. A company's or a person's effective tax rate may be determined using the following formulae:

The formula for individuals;

Effective tax rate = Total tax expense / Taxable income

The formula for a company;

Effective tax rate = Total tax expense / EBT

Since EBT is equivalent to adding net income to total tax cost, the above calculation may be revised as follows.

Effective tax rate = Total tax expense / (Net income + Total tax expense)

The effective tax rate of a business may be determined using just the income statement, just as the effective tax rate of a person can be determined using only Form 1040. The form assesses the sum of tax the government must pay or reimburse based on a person's total taxable income. It is required when submitting a federal income tax return on behalf of an individual.

Interpretation of effective tax rate

In almost all circumstances, there is a disparity between the pre-tax income indicated on the revenue statement and taxable earnings recorded on the tax filing. As a result, the effective and marginal tax rates are seldom similar since the effective tax rate calculation employs pre-tax revenue from the financial statement. This accounting report follows accrual accounting.

Because most businesses are an incentive to delay paying the government, the effective tax rate is often less than the marginal tax rate. Most corporations employ various accounting standards and requirements for financial disclosure vs. filing tax returns under US GAAP reporting, as described in the sections below.

Depreciation GAAP compared to fiscal management

A possible explanation for why the marginal and effective tax rates often vary is the idea of depreciation, which is the distribution of capital expenditure over the practical lifespan of a fixed asset.

    Financial disclosure: Most businesses use straight-line depreciation, where the PP&E is depreciated in equal quantities yearly.

    Filing taxes: The Internal Revenue Service (IRS), on the contrary, mandates accelerated depreciation for tax reasons, leading to deferred tax liabilities (DTLs).

The depreciation expenditure reported in previous periods for tax reasons is more than the amount recognized on GAAP reports. However, these tax variations are just transient, and the cumulative depreciation is equivalent at the conclusion.

A turning point in the asset's lifespan is reached when the depreciation reported for tax reasons is less than the amount declared on the accounting records; the DTL eventually approaches zero.

Net operating losses (NOLs)

Many businesses make significant losses in prior years and obtain tax credits that may be transferred to following periods once profitable, known as net operating loss (NOL) carry-forwards. A prosperous corporation may use previously accrued tax credits to lower taxes in both current and future cycles, resulting in a tax difference under book and fiscal accounting.

Approved write-offs

If an organization's debt or accounts receivable (A/R) are declared inaccessible, referred to as "Bad Debt" and "Bad AR," respectively, deferred tax assets (DTAs) are formed, resulting in tax disparities. The write-off is shown on the financial report as a write-off; nonetheless, it is not taken away from the company's tax filings.

Comparison of the marginal tax rate and the effective tax rate

Differences exist between the marginal tax rate (how much an increase in income results in corresponding tax liability) and the effective tax rate. For individuals and businesses alike, the effective tax rate reflects their true tax burden more accurately than the marginal tax rate.

Remember that the highest tax bracket an individual or business belongs to determines the marginal tax rate, while the effective tax rate is the average of all tax rates. A person's tax rate in the United States rises when their income rises over specific thresholds. Despite having the same income in the highest marginal tax band, two people might have drastically different effective tax rates.

The effective tax rate for a person is less than the marginal tax rate. Your earnings are segmented at various points based on the marginal tax rate. The tax rate is lower for the primary income level and increases exponentially for higher incomes. Taxes are calculated depending on the levels in between for any amounts that fall there.

 U.S. government tax rates

Tax rates at the federal level are set by legislation. The internal revenue service (IRS) enforces these thresholds in the United States. Taxpayers are placed into different tax brackets based on income and filing status.

The importance of the effective tax rate

The effective tax rate is one statistic investors use to gauge a company's profitability. This figure is subject to significant annual fluctuations. It is not always easy to determine what causes a change in the effective tax rate. It is possible, for instance, that a business is manipulating its asset accounts to lower its tax bill rather than making genuine changes in management or procedure.

Remember that businesses often create two financial statements, one of which is the reported financials like an income statement. The other is for accounting and tax reasons. Discrepancies may arise between the two papers due to differences in the treatment of expenses that qualify as tax deductions or credits. The effective tax rate of a business is lower if it makes better use of tax deductions and credits than if it does not.

Which income group has the highest effective tax rate?

The effective tax rate may be higher for those in the highest marginal tax band since a greater proportion of their income is subject to taxation at that rate. Taxpayers in this category may have the financial wherewithal to engage in tax evasion tactics that lower their taxable income and, therefore, their effective tax rate.

What can I do to lower my marginal tax rate?

Tax-free income is a great way for businesses and individuals to lower their effective tax rates. It might be a gift or tax-free money from sources like municipal bond interest or disability insurance. Tax breaks exist, for example, if you sell your property and fulfill the criteria to exempt the profit from tax reporting or make a qualifying distribution from your Roth IRA.

Is it possible to have a negative effective tax rate?

Yes, it is possible. Taxpayers who get a refund are counted as having an effective tax rate in the negative.

Do multibillionaires have lower tax rates?

The actual rate of taxation paid by individuals and businesses will vary. However, many of the rich can avoid paying taxes on their income. Think of a rich person who uses the value of their investments as collateral to get low-interest personal loans. If a person does not sell their stocks, they have no taxable gain to report (and pay taxes on). Some multibillionaires can pay extremely minimal effective tax rates because of these and other portfolio and financial strategy practices.


An individual's effective tax rate is the proportion of tax they owe on their taxable revenue. It depends on brackets created and upheld by the IRS. One may calculate their effective tax rate by dividing the total tax by the taxable earnings from Form 1040. Companies' effective tax rate is computed by dividing the total tax by profits before interest.
