NOTE 13:-

TAXES ON INCOME

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "TCJA"). The TCJA makes broad and complex changes to the Code. The changes include, but are not limited to:

1. A corporate income tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017 ("Rate Reduction");

2. The transition of U.S international taxation from a worldwide tax system to a territorial system by providing a 100 percent deduction to an eligible U.S. shareholder on foreign sourced dividends received from a foreign subsidiary;

3. A one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017; and

4. Taxation of GILTI earned by foreign subsidiaries beginning after December 31, 2017. The GILTI tax imposes a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations.

The Company has not completed its accounting for the income tax effects of the TCJA. Where the Company has not yet been able to make reasonable estimates of the impact of certain elements, the Company has not recorded any amounts related to those elements and has continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect immediately prior to the enactment of the TCJA, pursuant to SEC Staff Accounting Bulletin No. 118.

Corporate tax rates:

Israeli companies are generally subject to corporate tax on their taxable income. As of 2017, the corporate tax rate is 24% (in 2016 and 2015, the corporate tax rate was 25% and 26.5%, respectively).

In December 2016, the Israeli Parliament approved the Economic Efficiency Law (Legislative Amendments for Applying the Economic Policy for the 2017 and 2018 Budget Years), 2016 which reduces the corporate income tax rate to 24% (instead of 25%) effective from January 1, 2017 and to 23% effective from January 1, 2018. Capital gains derived by an Israeli company are subject to the prevailing corporate tax rate.

Taxable income of the Company's subsidiary in Luxemburg, Switzerland and the United States is subject to the following tax rates:

	Year ended December 31,
	2017			2016			2015

Luxemburg		29	%		29	%		29	%
Switzerland		24	%		24	%		24	%
United States		34	%		34	%		34	%
Germany		16	%		16	%		16	%


	c.	Tax assessments:

The Company has final tax assessments through the tax year 2013.

Deferred tax assets and liabilities:

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Deferred tax assets and liabilities mainly derive from the acquisitions of commercial buildings in Switzerland. The deferred taxes are computed at the average tax rate of 24%, based on the corporate income tax in Switzerland, which is the tax rate that will be in effect when the differences are expected to reverse.

Significant components of the Company and its subsidiary deferred tax assets are as follows:

	December 31,
	2017			2016
Deferred tax assets:
Net Operating losses	$	24,972		$	28,091

Net operating losses carry-forward:

Through December 31, 2017, Optibase Ltd. had net operating losses carry-forward for tax purposes in Israel of approximately $ 68,000 which may be carried forward and offset against taxable income in the future, for an indefinite period.

As of December 31, 2017, Optibase Inc. had U.S. federal net operating loss carry-forward of approximately $ 37,000 that can be carried forward and offset against taxable income for 20 years, no later than 2037. Utilization of U.S. net operating losses may be subject to the substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986, and similar state provisions. The annual limitation may result in the expiration of net operating losses before utilization. Based upon the weight of available evidence, which includes the Company's historical operating performance and the recorded cumulative net losses in all prior fiscal periods, the Company has provided a full valuation allowance against it Israeli and U.S deferred tax assets.
