INCOME TAXES [Text Block]	NOTE 21 - INCOME TAXES Income tax expense includes Puerto Rico and USVI income taxes as well as applicable U.S. federal and state taxes. The Corporation is subject to Puerto Rico income tax on its income from all sources. As a Puerto Rico corporation, First BanCorp. is treated as a foreign corporation for U.S. and USVI income tax purposes and, accordingly, is generally subject to U.S. and USVI income tax only on its income from sources within the U.S. and USVI or income effectively connected with the conduct of a trade or business in those jurisdictions. Any such tax paid in the U.S. and USVI is also creditable against the Corporation’s Puerto Rico tax liability, subject to certain conditions and limitations. Under the Puerto Rico Internal Revenue Code of 2011, as amended (the “2011 PR Code”), the Corporation and its subsidiaries are treated as separate taxable entities and are generally not entitled to file consolidated tax returns and, thus, the Corporation is generally not entitled to utilize losses from one subsidiary to offset gains in another subsidiary. Accordingly, in order to obtain a tax benefit from a net operating loss (“NOL”), a particular subsidiary must be able to demonstrate sufficient taxable income within the applicable NOL carry-forward period. Pursuant to the 2011 PR Code, the carry-forward period for NOLs incurred during taxable years that commenced after December 31, 2004 and ended before January 1, 2013 is 12 years; for NOLs incurred during taxable years commencing after December 31, 2012, the carryover period is 10 years. The 2011 PR Code allows entities organized as limited liability companies to elect to become a non-taxable “pass-through” entity and utilize losses to offset income from other “pass-through” entities, subject to certain limitations, with the remaining net income passing-through to its partner entities. The 2011 PR Code also provides a dividend received deduction of 100% on dividends received from “controlled” subsidiaries subject to taxation in Puerto Rico and 85% on dividends received from other taxable domestic corporations. On December 10, 2018, the Governor of Puerto Rico signed into law Act 257 (“Act 257”) to amend some of the provisions of the 2011 PR Code, as amended. Act 257 introduced various changes to the income tax regime in the case of individuals and corporations, and the sales and use taxes, which took effect on January 1, 2019, including, among others, (i) a reduction in the Puerto Rico maximum corporate tax rate from 39% to 37.5%; (ii) an increase in the net operating and capital losses usage limitation from 80% to 90%; (iii) amendments to the provisions related to “pass-through” entities that provide that corporations that own 50% or more of a partnership will not be able to claim a current or carryover non partnership NOL deduction against a partnership distributable share, adversely impacting a tax action taken in 2017 for FirstBank Insurance under which the Corporation was previously allowed to offset pass-through income earned by FirstBank Insurance with net operating losses at the holding company level; and (iv) other limitations on certain deductions, such as meals and entertainment deductions. The Corporation has maintained an effective tax rate lower than the maximum statutory rate mainly by investing in government obligations and MBS exempt from U.S. and Puerto Rico income taxes and by doing business through an International Banking Entity (“IBE”) unit of the Bank, and through the Bank’s subsidiary, FirstBank Overseas Corporation, whose interest income and gain on sales is exempt from Puerto Rico income taxation. The IBE and FirstBank Overseas Corporation were created under the International Banking Entity Act of Puerto Rico, which provides for total Puerto Rico tax exemption on net income derived by IBEs operating in Puerto Rico on the specific activities identified in the IBE Act. An IBE that operates as a unit of a bank pays income taxes at the corporate standard rates to the extent that the IBE’s net income exceeds 20% of the bank’s total net taxable income. For the first quarter of 2019, the Corporation recorded an income tax expense of $17.6 million, compared to $7.8 million for the same period in 2018. The increase was mostly attributable to higher taxable income when compared to the same period in 2018. For the quarter ended March 31, 2019, the Corporation calculated the provision for income taxes by applying the estimated annual effective tax rate for the full fiscal year to ordinary income or loss. In the computation of the consolidated worldwide annual estimated effective tax rate, ASC Topic 740-270, “Income Taxes” (“ASC Topic 740-270”) requires the exclusion of legal entities with pre-tax losses from which a tax benefit cannot be recognized. The Corporation’s estimated annual effective tax rate in the first quarter of 2019, excluding entities from which a tax benefit cannot be recognized and discrete items, was 28% compared to 27% for the first quarter of 2018. The estimated annual effective tax rate including all entities for 2019 was 29% (26% excluding discrete items), compared to 19% for the first quarter of 2018, (23% excluding discrete items). The Corporation’s net deferred tax asset amounted to $306.0 million as of March 31, 2019, net of a valuation allowance of $95.6 million, and management concluded, based upon the assessment of all positive and negative evidence, that it is more likely than not that the Corporation will generate sufficient taxable income within the applicable NOL carry-forward periods to realize such amount. The net deferred tax asset of the Corporation’s banking subsidiary, FirstBank, amounted to $305.9 million as of March 31, 2019, net of a valuation allowance of $63.5 million, compared to a net deferred tax asset of $319.8 million, net of a valuation allowance of $68.1 million, as of December 31, 2018. The Corporation has U.S. and USVI sourced NOL carryforwards. Section 382 of the U.S. Internal Revenue Code (the “Section 382”) limits the ability to utilize U.S. and USVI NOLs for income tax purposes in such jurisdictions following an event that is considered to be an ownership change. Generally, an “ownership change” occurs when certain shareholders increase their aggregate ownership by more than 50 percentage points over their lowest ownership percentage over a three-year testing period. Upon the occurrence of a Section 382 ownership change, the use of NOLs attributable to the period prior to the ownership change is subject to limitations and only a portion of the U.S. and USVI NOLs may be used by the Corporation to offset its annual U.S. and USVI taxable income, if any. In 2017, the Corporation completed a formal ownership change analysis within the meaning of Section 382 covering a comprehensive period, and concluded that an ownership change had occurred during such period. The Section 382 limitation has resulted in higher U.S. and USVI income tax liabilities than we would have incurred in the absence of such limitation. The Corporation has mitigated to an extent the adverse effects associated with the Section 382 limitation as any such tax paid in the U.S. or USVI can be creditable against Puerto Rico tax liabilities or taken as a deduction against taxable income. However, our ability to reduce our Puerto Rico tax liability through such a credit or deduction depends on our tax profile at each annual taxable period, which is dependent on various factors. For the first quarter of 2019, the Corporation incurred an income tax expense of approximately $1 million related to its U.S. operations, compared to $1.6 million for the same period in 2018. The limitation did not impact the USVI operations in the first quarter of 2019 and 2018, respectively. As of March 31, 2019, the Corporation did not have Unrecognized Tax Benefits recorded on its books. The Corporation classifies all interest and penalties, if any, related to tax uncertainties as income tax expense. Audit periods remain open for review until the statute of limitations has passed. The statute of limitations under the 2011 PR Code is four years; the statute of limitations for U.S. and USVI income tax purposes is three years after a tax return is due or filed, whichever is later, for each. The completion of an audit by the taxing authorities or the expiration of the statute of limitations for a given audit period could result in an adjustment to the Corporation’s liability for income taxes. Any such adjustment could be material to the results of operations for any given quarterly or annual period based, in part, upon the results of operations for the given period. For U.S. and USVI income tax purposes, all tax years subsequent to 2012 remain open to examination. For Puerto Rico tax purposes, all tax years subsequent to 2013 remain open to examination.
