Goodwill is an intangible asset that arises when one company purchases another for an amount greater than the value of its assets acquired after accounting for the liabilities assumed. Examples of goodwill include an outstanding management team or a reputation for exceptional customer service. These things are by nature nearly impossible to quantify, though through the acquisition process it is possible to put a monetary value on them by considering the true value of the company including all tangible assets and net of any liabilities.
One consequence of these events was the passage of Sarbanes–Oxley Act in the United States 2002, as a result of the first admissions of fraudulent behavior made by Enron. The act significantly raises criminal penalties for securities fraud, for destroying, altering or fabricating records in federal investigations or any scheme or attempt to defraud shareholders.[75]
Tax gain-loss harvesting is another form of tax planning or management relating to investments. It is helpful because it can use a portfolio's losses to offset overall capital gains. According to the IRS, short and long-term capital losses must first be used to offset capital gains of the same type. In other words, long-term losses offset long-term gains before offsetting short-term gains. As of 2018, short-term capital gains, or earnings from assets owned for less than one year, are taxed at ordinary income rates. 

Accounting or accountancy is the measurement, processing, and communication of financial and non financial information about economic entities[1][2] such as businesses and corporations. Accounting, which has been called the "language of business",[3] measures the results of an organization's economic activities and conveys this information to a variety of users, including investors, creditors, management, and regulators.[4] Practitioners of accounting are known as accountants. The terms "accounting" and "financial reporting" are often used as synonyms.

Tax credits are extremely valuable breaks for taxpayers. Credits lead to a greater reduction in tax than deductions because they are directly applied to your tax bill in a dollar-for-dollar manner. For instance, a $1,000 credit would cut your tax bill by $1,000, but a $1,000 deduction would reduce your taxes by less than $1,000 -- more specifically, typically somewhere between $100 and $370 under current tax law. In particular, the following tax credits are among the most common and can produce significant savings. 
In addition to being the largest bankruptcy reorganization in American history, the Enron scandal undoubtedly is the biggest audit failure.[73] It involved a financial scandal of Enron Corporation and their auditors Arthur Andersen, which was revealed in late 2001. The scandal caused the dissolution of Arthur Andersen, which at the time was one of the five largest accounting firms in the world. After a series of revelations involving irregular accounting procedures conducted throughout the 1990s, Enron filed for Chapter 11 bankruptcy protection in December 2001.[74]
Tax planning is the analysis of a financial situation or plan from a tax perspective. The purpose of tax planning is to ensure tax efficiency. Through tax planning, all elements of the financial plan work together in the most tax-efficient manner possible. Tax planning is an essential part of an individual investor's financial plan. Reduction of tax liability and maximizing the ability to contribute to retirement plans are crucial for success.
Organizations in individual countries may issue accounting standards unique to the countries. For example, in the United States the Financial Accounting Standards Board (FASB) issues the Statements of Financial Accounting Standards, which form the basis of US GAAP,[1] and in the United Kingdom the Financial Reporting Council (FRC) sets accounting standards.[53] However, as of 2012 "all major economies" have plans to converge towards or adopt the IFRS.[11]

The total sum of state and local income taxes, real estate taxes, and personal property taxes (such as car registration fees) up to $10,000, or $5,000 if you're married and file a separate return. You can substitute sales taxes you paid for income taxes if this is more beneficial for you, but you cannot include both sales and income taxes—you must choose one or the other.

Saving via a retirement plan is a popular way to efficiently reduce taxes. Contributing money to a traditional IRA can minimize gross income up to $6,500. As of 2018, if meeting all qualifications, a filer under age 50 receives a reduction of $6,000 and a reduction of $7,000 if age 50 or older. For example, if a 52-year-old male with an annual income of $50,000 who made a $6,500 contribution to a traditional IRA has an adjusted gross income of $43,500, the $6,500 contribution would grow tax-deferred until retirement.
Managerial accounting uses much of the same data as financial accounting, but it organizes and utilizes information in different ways. Namely, in managerial accounting, an accountant generates monthly or quarterly reports that a business's management team can use to make decisions about how the business operates. Managerial accounting also encompasses many other facets of accounting, including budgeting, forecasting and various financial analysis tools. Essentially, any information that may be useful to management falls underneath this umbrella.
