Income tax expense includes U.S. (federal and state) and foreign income taxes. Tax legislation commonly known as the Tax Cuts and Jobs Act of 2017 (the "2017 Tax Act") includes a mandatory one-time tax on accumulated earnings of foreign subsidiaries, and as a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued have now been subject to U.S. tax. Notwithstanding the U.S. taxation of these amounts, Amazon.com intends to continue to invest most or all of these earnings, as well as the capital in these subsidiaries, indefinitely outside of the U.S. and does not expect to incur any significant, additional taxes related to such amounts.

Deferred income tax balances reflect the effects of temporary differences between the carrying amounts of assets and liabilities and their tax bases and are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered.

Deferred tax assets are evaluated for future realization and reduced by a valuation allowance to the extent Amazon.com believes they will not be realized. Amazon.com considers many factors when assessing the likelihood of future realization of the deferred tax assets, including the recent cumulative loss experience and expectations of future earnings, capital gains and investment in such jurisdiction, the carry-forward periods available to Amazon.com for tax reporting purposes, and other relevant factors.

Amazon.com utilizes a two-step approach to recognizing and measuring uncertain income tax positions (tax contingencies). The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. Amazon.com considers many factors when evaluating the tax positions and estimating the tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. Amazon.com includes interest and penalties related to the tax contingencies in income tax expense.
