1. Corporate Taxes

Income taxes in the United States are an enormous and complex issue. Corporate taxes are especially complicated because of the inherent complexities of corporations themselves. Corporations may be taxed on their incomes, property, or their very existence. The types and rates of taxes vary depending on the jurisdiction in which the corporation is organized or acts.


Maryland imposes a tax on corporations organized within its borders based on the number of shares of capital stock they issue.

Corporate taxation differs depending upon the legal form of the corporation. Which legal form to take is driven by the objectives of the company, but taxation also plays a vital role. Tax law contains built-in trade-offs for each corporate form, and companies often must give up some liability protection or flexibility.

Type of Corporation Type of Tax
Sole Proprietorship A sole proprietorship is a business entity that is owned and run by a single individual. There is no legal distinction between the owner and the business. They are one and the same for tax purposes. The individual reports all income and expenses for the business on his or her personal income tax statement. In other words, the business is not taxed as a separate entity.

There is no method for sheltering tax in a sole proprietorship. Earnings are taxed regardless if they are actually distributed. In addition, the individual is held liable for the actions of the business, meaning claimants can pursue the personal property of the individual should solvency issues arise.
Partnership A partnership is a business entity with two or more owners. For tax purposes, partnerships are treated similarly to a sole proprietorship – the owners pay tax on their “distributive share” of the business’s taxable income. The partners must agree on how the income of the business will be allocated. Partners are jointly liable for the operations of the business. Thus, one partner may pursue one or any number of other partners in the case of personal damages or losses.
C Corporation A C corporation refers to any corporation that is taxed separately from its owners. Although vastly outnumbered by sole proprietorships and partnerships, most of the largest companies in the U.S. are C corporations. Owners of C corporations are personally protected from any liability of the company – an idea known as the corporate veil. In return, the earnings of a C corporation are taxed both on the entity level and the individual level.
S Corporation The S corporation is a hybrid entity wherein the income, deductions and tax credits of the business are taxed at the shareholder level as opposed to the entity level. However, owners enjoy the same limited liability awarded to C corporations. In exchange for this luxury, rules are placed on the types of corporations that can elect S status:
  • The corporation must have only one class of stock.
  • It must be a domestic corporation (owned by U.S. citizens).
  • It must not have more than 100 shareholders (spouses are considered to be one shareholder).
  • Shareholders generally cannot include corporations or partnerships (certain trusts, estates and tax-exempt corporations are permitted).
  • Profits and losses must be allocated to shareholders proportionately to each one’s interest in the business.
Limited Liability Company (LLC) The LLC is similar to that of the S corporation – a hybrid form of ownership. It bears characteristics of a corporation and a sole proprietorship. It provides for limited liability in the event of a dispute, provides ease of transferability in the event of a sale or death of owner(s), and does not limit the types or number of shareholders.

In the United States, taxable income for a corporation is defined as all gross income less allowable tax deductions and tax credits. This income is taxed at a specified corporate tax rate. This rate varies by jurisdiction and is generally the same for different types of income. Some systems have graduated tax rates – corporations with lower levels of income pay a lower rate of tax – or impose tax at different rates for different types of corporations.

In the US, federal rates range from 15% to 35%. States charge rates ranging from 0% to 10%, deductible in computing federal taxable income. Some cities charge rates up to 9%, also deductible in computing federal taxable income. Corporations are also subject to property tax, payroll tax, withholding tax, excise tax, customs duties and value added tax. However, these are rarely referred to as “corporate tax.”

2. Tax Deductions

A tax deduction is a sum that can be removed from tax calculations. Specifically, it is a reduction of the income subject to tax. Often these deductions are subject to limitations or conditions.

Expenses incurred in order to generate profit for a company are referred to as business expenses. These can be categorized into cost of goods sold and ordinary expenses – also known as trading or necessary expenses.

  • Cost of Goods Sold: Nearly all income tax systems allow a deduction for cost of goods sold. This can be considered an expense or simply a reduction in gross income, which is the starting point for determining federal and state income tax. Several complexities must be factored in when determining cost of goods sold, including assigning a dollar amount to a good/service when it is difficult to assign value, deciding which period costs will be recognized, and determining whether costs of goods not sold or those that have been depreciated will be recorded.
  • Ordinary Expenses: According to tax law, the United States allows as a deduction “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business…”. Generally, this business must be regular, continuous, substantial, and entered into with an expectation of profit. Ordinary and necessary expenses tend to be those that are appropriate to the nature of the business, the sort expected to help produce income and promote the business, and those that are not lavish and extravagant.


An ordinary expense could be interest paid on debt, or interest expense incurred by a corporation in carrying out its trading activities. Such an expense comes with limitations, though, such as limiting the amount of deductible interest that can be paid to related parties.

Other types of expenses such as non-business expenses may be tax deductible as well. A loss recognized on a non-business asset is typically classified as a capital loss. This can have an impact on one's realized capital gains and must be accounted for appropriately.

Corporate taxes in the United States are considered to be progressive. That is to say, taxes are charged at a higher rate as income grows. To fully understand the effect of tax deductions, we must consider the marginal tax rate, which is the rate of tax paid on the next or last unit of currency of taxable income. The marginal tax rate is dependent upon a jurisdiction’s tax structure, usually referred to as tax brackets. To determine the after-tax cost of a deductible expense, we simply multiply the cost by one minus the appropriate marginal tax rate.

Tax deductions and tax credits are often incorrectly equated. While a deduction is a reduction of the level of taxable income, a tax credit is a sum deducted from the total amount of tax owed. It is a dollar-for-dollar tax saving. For example, a tax credit of $1,000 reduces taxes owed by $1,000, regardless of the marginal tax rate. A tax credit may be granted in recognition of taxes already paid, as a subsidy, or to encourage investment or other behaviors.

3. Depreciation

Many tax systems require that the cost of items likely to produce future benefits be capitalized. Such assets include property and capital equipment that represent a commitment of resources over several periods. In accounting, the profits (net income) from an activity must be reduced by the costs associated with that activity.

When an asset will be used in operations for several periods, tax systems often allow the allocation of the costs to periods in which the assets are used. In the U.S., this allocation is known as depreciation expense. It is important to reasonably estimate the useful life of the asset under depreciation in time-units. Then it is important to calculate the corresponding depreciation rate that will result in extinguishing the value of the asset from the books when the estimated useful life ends. There are several methods for achieving this goal.

Type of Depreciation Description
Straight-Line Method This method reduces the book value of an asset by the same amount each period. This amount is determined by dividing the total value of the asset, less its salvage value, by the number of periods in its useful life. This amount is then deducted from income in each applicable period. Straight-line depreciation is the simplest and most-often-used technique.

The economic reasoning behind the straight-line method involves the acceptance that depreciation is an approximation of the rate at which an asset transfers value to the operations of a business. As a result, we should use the most economical, or simplest, method to calculate and incorporate its costs.
Declining Balance Method This method provides for a higher depreciation expense in the first year of an asset’s life and gradually decreases expenses in subsequent years. This may be a more realistic reflection of the actual expected benefit from the use of the asset because many assets are most useful when they are new.

Under this method, the annual depreciation expense is found by multiplying book value of the asset each year by a fixed rate. Since this book value will differ from year to year, the annual depreciation expense will subsequently differ. The most commonly used rate is double the straight-line rate. Since the declining balance method will never fully amortize the original cost of the asset, the salvage value is not considered in determining the annual depreciation.
Activity Depreciation Methods Activity depreciation methods are not based on time, but on a level of activity. When the asset is acquired, its life is estimated in terms of this level of activity. This could be miles driven for a vehicle or a cycle count for a machine. Each year, the depreciation expense is calculated by multiplying the rate by the actual activity level.

big idea
Depreciation expense affects net income in each period of an asset’s useful life. Therefore, it can be deducted from taxes owed in each of these periods. In other words, depreciation allows a company to properly identify the amount of income it generates in a given period. As with all expenses, a dollar of taxes that a company can defer until later is a dollar that can be used in profit generating operations today.

4. Individual Taxes

In the US, there is a broad variety of state, local, and federal taxes that must be taken into account. Below is a chart that depicts the level of tax received by the United States federal government from each source in 2010.

4a. Income Taxes
When one has a complex income, owns multiple properties, or is involved in the importation of goods, it is best to solicit the services of a tax professional, such as a certified public accountant (CPA).

Individual taxes can generally be defined as either direct or indirect.

  • A direct tax is one imposed upon an individual person or on property, as opposed to a tax imposed upon a transaction. In U.S. constitutional law, direct taxes refer to poll taxes and property taxes, which are based on simple existence or ownership.
  • Indirect taxes, such as sales or value-added tax, are imposed only when a taxable transaction occurs. People have the freedom to engage in or refrain from such transactions, whereas a direct tax is typically imposed upon an individual in an unconditional manner.
Personal income tax is generally the largest source of tax revenue in the United States. Taxes based on income are imposed at the federal, most state, and some local levels. Income tax is levied on the total income of the individual less deductions reducing an individual’s taxable income, and credits, a dollar-for-dollar reduction of total tax liability.

The tax system allows for personal exemptions, as well as certain “itemized deductions,” including:

  • Medical expenses (over 7.5% of adjusted gross income)
  • State and local income and property taxes
  • Interest expense on certain home loans
  • Gifts of money or property to qualifying charitable organizations, subject to certain maximum limitations
  • Losses on non-income-producing property due to casualty/theft
  • Contribution to certain retirement or health savings plans
  • Certain educational expenses
Income tax is often collected on a pay-as-you-earn basis (i.e., withholding taxes from wages). Small corrections are usually made after the end of the tax year. These corrections take one of two forms: payments to the government for taxpayers who have not paid enough during the tax year; and government tax refunds for those who have overpaid.

Federal and many state income tax rates are graduated or progressive–they are higher (graduated) at higher levels of income. The income level at which various tax rates apply for individuals varies by filing status. The income level at which each rate starts generally is higher; therefore, tax is lower for married couples filing a joint return or single individuals filing as head of household. Individuals are subject to federal graduated tax rates from 10% to 35%. State income tax rates vary from 1% to 16%, including local income tax where applicable.

4b. Other Taxes
Other individual taxes include:

Types of Tax Description
Payroll Tax Payroll taxes are imposed on employers and employees and on various compensation bases. These include income tax withholding, social security and medicare taxes, and unemployment taxes.
Sales Tax Sales tax is an indirect tax levied on the state level, including taxes on retail sale, lease and rental of goods, as well as some services. Many cities, counties, transit authorities, and special purpose districts impose an additional local sales tax. Sales tax is calculated as the purchase price times the appropriate tax rate. Tax rates vary widely by jurisdiction from less than 1% to over 10%. Nearly all jurisdictions provide numerous categories of goods and services that are exempt from sales tax or taxed at a reduced rate.
Property Tax Most jurisdictions below the state level impose a tax on interests in real property (land, buildings, and permanent improvements). Property tax is based on fair market value of the subject property. The amount of tax is determined annually based on the market value of each property on a particular date. The tax is computed as the determined market value times an assessment ratio times the tax rate.
Estate and Gift Tax The estate tax is an excise tax levied on the right to pass property at death. It is imposed on the estate, not the beneficiary. Gift taxes are levied on the giver (donor) of property where the property is transferred for less than adequate consideration. The federal gift tax is computed based on cumulative taxable gifts, and is reduced by prior gift taxes paid. The federal estate tax is computed on the sum of taxable estate and taxable gifts, and is reduced by prior gift taxes paid. These taxes are computed as the taxable amount times a graduated tax rate (up to 35%). Taxable values of estates and gifts are the fair market value.

In this lesson, you learned about corporate taxes and received a brief overview of the tax treatment of different types of corporations in the United States. Corporations pay many different kinds of taxes, but benefit from tax deductions for business expenses incurred in order to generate a profit. Tax deductions, not to be confused with tax credits, reduce corporate taxable income. Depreciation expenses also reduce taxable income, and may be calculated through the straight-line method, the declining balance method, or through activity depreciation methods. Individual taxes in the United States comprise the largest source of income for the government, and take the form of income taxes, payroll taxes, sales tax, property tax, and gift and estate taxes.
