Accounting research is carried out both by academic researchers and practicing accountants. Methodologies in academic accounting research include archival research, which examines "objective data collected from repositories"; experimental research, which examines data "the researcher gathered by administering treatments to subjects"; analytical research, which is "based on the act of formally modeling theories or substantiating ideas in mathematical terms"; interpretive research, which emphasizes the role of language, interpretation and understanding in accounting practice, "highlighting the symbolic structures and taken-for-granted themes which pattern the world in distinct ways"; critical research, which emphasizes the role of power and conflict in accounting practice; case studies; computer simulation; and field research.[66][67]
Hiring a certified public accountant (CPA) could be a better option instead of doing your taxes by yourself, but it depends on your tax situation and preferences. Having a CPA do your taxes is usually recommended if you have a business or any type of side job, or if you’ve been contacted by the IRS for a tax-related matter. Others who can benefit are those who own rental properties or have many assets. You can also hire a CPA if you need help understanding what deductions or credit you might qualify for.
The history of accounting is thousands of years old and can be traced to ancient civilizations.[12][13][14] The early development of accounting dates back to ancient Mesopotamia, and is closely related to developments in writing, counting and money;[12] there is also evidence of early forms of bookkeeping in ancient Iran,[15][16] and early auditing systems by the ancient Egyptians and Babylonians.[13] By the time of Emperor Augustus, the Roman government had access to detailed financial information.[17]
Just as managerial accounting helps businesses make decisions about management, cost accounting helps businesses make decisions about costing. Essentially, cost accounting considers all of the costs related to producing a product. Analysts, managers, business owners and accountants use this information to determine what their products should cost. In cost accounting, money is cast as an economic factor in production, whereas in financial accounting, money is considered to be a measure of a company's economic performance.

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. 


Meanwhile, the Lifetime Learning tax credit offers additional educational tax breaks even beyond traditional college. A 20% credit on up to $10,000 in eligible expenses every year is available to taxpayers making less than $59,000 if they're single or $118,000 if they're filing jointly, with reduced credits available up to $69,000 in income for singles and $138,000 for joint filers. This credit is available for graduate school, vocational training, and certain other nontraditional educational expenses.
In most cases, accountants use generally accepted accounting principles (GAAP) when preparing financial statements in the U.S. GAAP is a set of standards and principles designed to improve the comparability and consistency of financial reporting across industries. Its standards are based on double-entry accounting, a method in which every accounting transaction is entered as both a debit and credit in two separate general ledger accounts that will roll up into the balance sheet and income statement.
