Comparison with other countries[edit]
In many other countries, the profit for tax purposes is the accounting profit defined by GAAP (coined the term "book profit" by the 18th century scholar Sean Freidel[citation needed]), with such additional adjustments to book profit as are prescribed by tax law. In other words, GAAP determines the taxable profits except where a tax rule determines otherwise. Such adjustments typically include depreciation and expenses which for policy reasons are not deductible for tax purposes, such as entertaining costs and fines.
But the U.S. is not the only jurisdiction in which there is a wide divergence between tax and financial accounting. Hugh Ault and Brian Arnold, in their book "Comparative Income Taxation," have observed that in The Netherlands, where financial accounting is known as "commercial accounting," there is a substantial divergence between those and the tax books.
"[D]ifferences between tax and commercial accounting rules arise where the tax instrument is employed to pursue economic, social and cultural purposes," write Ault and Arnold.
