Here is a glossary of terms (a work in progress) with simplified definitions:
After-tax: After-tax means a deduction from an employee’s wages that does not reduce the employee’s taxable income. (Also see pre-tax)
After-tax Basis: When a taxpayer makes non-deductible contributions to an IRA, the non-deductible contributions give the taxpayer after-tax basis in the IRA. When the taxpayer withdraws money from the IRA, the after-tax portion is not taxable. (Also see IRA)
AMT: Stands for “alternative minimum tax.” AMT is an alternative tax calculation that affects higher-income individuals. The AMT calculation takes away personal exemptions and many itemized deductions in arriving at taxable income for AMT purposes.
Asset: For businesses, an asset is something the business purchases that has a useful life of one year or more (equipment, for example). For individuals, things such as houses, stocks and other such items are considered assets.
Bonus Depreciation: A special, accelerated depreciation deduction available for purchases of brand-new assets. Bonus depreciation allows immediate expensing of a certain portion of the purchase price of the asset, with the remaining cost being depreciated. The bonus depreciation amount is set by Congress and varies from 100% (in other words, immediate expensing in full) to some lesser percentage (oftentimes 50%). (Also see Asset, Depreciation, Section 179)
Capital gain/capital loss: Gain or loss from the sale of an asset. Long-term capital gains may be subject to special, preferential tax rates. Capital losses are limited to $3,000/year. (Also see Asset)
Capital loss limit: Tax law places a limit on how much a taxpayer can deduct in capital losses each year. That limit is $3,000/year. Unused losses in one year can be carried forward to be used in future years. (Also see Capital gain/capital loss)
C-Corporation: By default, any incorporated business entity is taxed as a C-Corporation. A corporation can elect to be taxed as an S-Corporation. A C-Corporation is a separate taxpaying entity. The results of C-Corporation operations stay within the corporation, and the corporation itself pays taxes on corporate net income.
Child tax credit: A $1,000 per child tax credit available for parents who have kids under the age of 17. The credit is non-refundable. However, part of the credit may be refundable depending on the amount of earned income the taxpayer has. (Also see Refundable Credits, Refundable Child Tax Credit)
Community Property: Most states follow “common law,” but 9 states in the United States follow “community property” laws. When married couples in community property states file separate tax returns, they must employ community property rules. Those rules require splitting most of items of income 50/50 between both spouses. The 9 states that follow community property laws are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin.
Defense of Marriage Act (often abbreviated as DOMA): A federal law passed in 1996 that said, for all federal purposes, that marriage is defined as “one man, one woman.” Because of DOMA, the federal government did not recognize any same-sex marriage, civil unions or domestic partnerships. The U.S. Supreme Court ruled the law unconstitutional on June 26, 2013.
Dependent: Refers to a taxpayer’s child (if the taxpayer claims the child on the tax return) or others that the taxpayer supports. A dependency exemption and certain other tax benefits are available for claiming dependents on a tax return. (Also see Personal Exemptions)
Depreciation (for taxes): For tax purposes, depreciation is a deduction taken by businesses on the purchase of assets. Rather than taking a deduction in full in the year of purchase, the deduction is spread over time. The IRS determines the length of time. For example, a computer is depreciated over 5 years because that’s the length of time for depreciating computers set out by the IRS.
Depreciation (for financial statements): Under Generally Accepted Accounting Principles, an asset is depreciated over its estimated useful life. For example, if a business determines that it will use a computer for 3 years and then replace it, the computer is depreciated over 3 years.
Draws: Withdrawals from a sole proprietorship or partnership by the proprietor. In a sole proprietorship, Draws are not deductible. In a partnership, draws are also not deductible but must be tracked because draws reduce the partner’s basis in the partnership.
Earned Income Credit (EIC) - A tax credit available to taxpayers between the ages of 25 and 65 whose income is below certain levels. The income level varies depending on filing status and how many children the taxpayer has. The credit is fully refundable. (Also see Filing Status, Refundable Credits)

Filing status - There are 5 filing statuses one can choose from when filing a federal income tax return: single, head of household, married filing jointly, married filing separately, and qualified widow(er). Each status comes with its own standard deduction, tax bracket, and (s0metimes) special rules or restrictions on certain deductions and credits.
529 Plan: A savings plan that lets a taxpayer save for their children’s college expenses. Money put into a 529 plan does NOT result in a federal tax deduction, but withdrawals (including earnings) are tax-free if used for college expenses. Many states, such as Iowa, allow for a deduction on the state tax return for money put into a 529 plan. For more information about Iowa 529 plans, visit the College Savings Iowa website.
Form K-1: A reporting form issued by partnerships, S-Corporations, estates and trusts. Form K-1 reports an individual shareholder’s or beneficiary’s share of the entity’s income and deductions for the year.

Gift tax: A federal tax assessed against the givers of gifts above a certain amount. For 2013, that amount is $14,000. If a person gives gifts to any one person that total more than $14,000 for the year, that person may need to file a gift tax return and potentially pay gift tax.

The test for someone to be a medical dependent is: did they live with the taxpayer all year and did the taxpayer provide more than half of their support? If so, they might be the taxpayer’s medical dependent.
Miscellaneous Itemized Deductions: Deductions for things such as unreimbursed employee expenses, expenses relating to investments, and fees for safe-deposit boxes at banks, among many other possibilities.

The deposit can still be made, but is not deductible on the taxpayer’s tax return. Non-deductible contributions give the taxpayer after-tax basis in their IRA. (Also see IRA, After-Tax Basis)
Non-refundable credit: A tax credit that reduces taxable income to $0 but cannot generate a refund in and of itself.
Passive Activity Losses: A passive activity is an investment activity in which a taxpayer doesn’t “actively participate.” In overly simplified terms, this means the taxpayer doesn’t work in the business day-to-day. There are limits on the amount of losses a taxpayer can deduct from passive activities.
Pass-through Entity: Sometimes called “flow-through” entities. This term refers to business entities that do not pay income taxes themselves.

In the year of the spouse’s death, the couple will file as married filing jointly. The surviving spouse can use Qualified Widow(er) as a filing status for the next two tax years after that.

Section 179: A deduction, similar to depreciation, that allows a business to expense 100% of the cost of an asset in the year of purchase. A business can take the Section 179 deduction on any assets it purchases, whether new or used. The deduction is limited to the business’s net income for the year.
Section 1231/1245: Both terms refer to business assets. Section 1245 refers to depreciation taken on assets. When those assets are sold at a gain, the depreciation that has been taken over the life of the asset may need to be claimed as ordinary income in the year of the sale. Any remaining gain after depreciation recapture is treated as a Section 1231 gain, which means losses are deductible in full, while gains are treated as capital gains.
