  • Accrual method

    Accounting method that reports income when earned (not necessarily received) and expenses when incurred (not necessarily paid), as opposed to the cash method.

  • Active Participation

    When a taxpayer makes significant rental or business management decisions, such as approving rental terms, repairs, expenditures, and new tenants (versus passive activity). Taxpayers who use a leasing agent or property manager are still considered active participants if they retain final management rights.

  • Active Pay

    The military income a service member receives while on active duty (versus retirement or retainer pay).

  • Actual Expense Method

    One of two methods for calculating business automobile expenses. For the actual expense method, the taxpayer determines the business portion of expenses for fuel, auto maintenance, parking fees and tolls, and auto loan interest. (The other method is the standard mileage method). The actual expense method is out of scope for the VITA/TCE programs.

  • Adjusted Basis

    The adjusted basis is the taxpayer’s basis in a home increased or decreased by certain amounts. Increases include additions or improvements to the home such as installing a recreation room or putting on a new roof. In order to be considered an increase, the improvement must have a useful life of more than one year. Repairs that maintain the home in good condition are not considered improvements and should not be added to the basis of the property.

B
  • BAH

    Basic allowance for housing, a type of excludable military income.

  • BAS

    Basic allowance for subsistence, a type of excludable military income.

  • Basis

    The basis in a home is determined by how the taxpayer obtained the home. If a taxpayer bought or built a home, the basis is what it cost the taxpayer to buy or build that home. If the taxpayer inherited the home, generally the basis is its fair market value on the date of the decedent’s death, or on the later alternate valuation date chosen by the representative for the estate. There are special rules for determining the basis of property received from decedents who died in 2010.

  • Before-tax Contributions

    Before-tax simply means that the employee did not pay taxes on the money at the time it was contributed, i.e., the taxpayer has no cost basis in the plan.

  • Blocked income

    Blocked income is when a taxpayer cannot convert foreign currency to U.S. dollars due to local law or local government policy. Special tax rules allow taxpayers with blocked income to delay reporting part of their income.

  • Bona Fide Residence Test

    To meet the bona fide residence test for the foreign earned income exclusion, taxpayers must show that they have set up permanent quarters in a foreign country for an entire, uninterrupted tax year.
