Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES NJR evaluates its tax positions to determine the appropriate accounting and recognition of potential future obligations associated with unrecognized tax benefits. During the three months ended December 31, 2016 and 2015, based on its analysis, the Company determined there was no need to recognize any liabilities associated with uncertain tax positions. To calculate the estimated annual effective tax rate, NJR considers forecasted pre-tax book income and estimated permanent book versus tax differences, as well as tax credits associated with solar and wind projects. For investment tax credits the estimate is based on solar projects that are probable of being completed and placed in service during the current fiscal year based on the best information available at each reporting period. For production tax credits the estimate is based on the forecast of electricity produced during the current fiscal year based on the best information available at each reporting period. Adjustments to the effective tax rate and management's estimates will occur as information and assumptions change. The forecasted effective tax rates for the three months ended December 31, 2016 and 2015, were 8.7 percent and 14.7 percent, respectively. The decreased effective tax rate is due primarily to a decrease in forecasted pre-tax income along with an increase in forecasted tax credits for the fiscal year ended September 30, 2017, compared with the prior fiscal year. Forecasted tax credits, net of deferred taxes, were $34.1 million and $26.8 million for fiscal 2017 and 2016, respectively. To the extent there are discrete tax items that are not included in the forecasted effective tax rate, the actual effective tax rate will differ from the estimated annual effective tax rate. The Company recognized $1.2 million and $1.6 million during the three months ended December 31, 2016 and 2015, respectively, in excess tax benefits associated with the vesting of share-based awards, as a component of income tax provision in its Unaudited Condensed Consolidated Statements of Operations. Since the tax effects of the awards are treated as a discrete item, NJR’s actual effective tax rate was 5.5 percent and 11.8 percent as of December 31, 2016 and 2015, respectively. As of December 31, 2016, the Company has federal and state income tax net operating losses of approximately $78.7 million and $323.9 million, respectively, which generally have a life of 20 years. The Company has recorded federal and state deferred tax assets of approximately $27.5 million and $19 million, respectively, on the Unaudited Condensed Consolidated Balance Sheets, reflecting the tax benefits associated with these net operating losses. As of September 30, 2016, the Company had federal and state income tax net operating losses of approximately $78.7 million and $310.6 million, respectively, deferred federal and state tax assets of approximately $27.5 million and $18.2 million, respectively. As of December 31, 2016 and September 30, 2016, the Company recorded a valuation allowance in the amount of $108,000 and $262,000, respectively, because it believes that it is more likely than not that the state net operating losses related to CR&R will expire unused. The Company expects to utilize all of the net operating losses not related to CR&R. In addition, as of December 31, 2016 and September 30, 2016, the Company had an ITC/PTC carryforward of approximately $79.1 million and $74 million, respectively, which has a life of 20 years. The Company expects to utilize this entire carryforward, which would begin to expire in fiscal 2034. In December 2015, the Consolidated Appropriations Act extended the 30 percent ITC for solar property that is under construction on or before December 31, 2019. The credit will decline to 26 percent for property under construction during 2020 and to 22 percent for property under construction during 2021. For any property that is under construction before 2022, but not placed in service before 2024 the ITC will be reduced to 10 percent. In addition, the PTC was extended for five years through December 31, 2019, with a gradual three year phase out for any project for which construction of the facility begins after December 31, 2016.
