New Accounting Pronouncements, Policy [Policy Text Block]	RECENT ACCOUNTING PRONOUNCEMENTS The Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers in May 2014. The new standard will supersede much of the existing authoritative literature for revenue recognition. In August 2015, the FASB also issued ASU No. 2015-14 which deferred the effective date of the new standard by one year. The standard and related amendments will be effective for the Company for its annual reporting period beginning July 1, 2018, including interim periods within that reporting period. Along with the deferral of the effective date, ASU No. 2015-14 allows early application as of the original effective date. Entities are allowed to transition to the new standard by either recasting prior periods or recognizing the cumulative effect as of the beginning of the period of adoption. In March 2016, the FASB issued ASU No. 2016-08, which addresses principal versus agent considerations under the new revenue standard. The Company is currently evaluating the newly issued guidance, including which transition approach will be applied and the estimated impact it will have on our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This ASU requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability (same treatment as debt discounts). ASU No. 2015-03 will be effective for the Company in its fiscal year ended June 30, 2017. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company currently classifies debt issuance costs as an asset, and will adopt these changes beginning July 1, 2016. ASU No. 2015-17 was issued by the FASB in November 2015 as part of the Simplification Initiative. This ASU eliminates the requirement to separate deferred income tax liabilities and assets into non-current and current amounts. ASU No. 2015-17 is effective for the Company for its annual reporting period beginning July 1, 2017 and early adoption is permitted. In the third quarter of fiscal 2016, management elected to early adopt and all deferred income tax assets and liabilities are reported as non-current. At March 31, 2016, the current portion of our deferred income tax liability was $7,034. Prior periods were not retrospectively adjusted. The FASB issued ASU No. 2016-02, Leases, in February 2016. This ASU aims to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and requiring disclosure of key information regarding leasing arrangements. ASU No. 2016-02 will be effective for Jack Henry's annual reporting period beginning July 1, 2019 and early adoption is permitted. The Company is currently assessing the impact this new standard will have on our consolidated financial statements. The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-Based Payment Accounting in March 2016. The new standard will simplify several aspects of the accounting for share-based payment transactions, including reporting of excess tax benefits and shortfalls, application of forfeiture rates, statutory minimum withholding considerations, and classification within the statement of cash flows. ASU No. 2016-09 is effective for the Company’s annual reporting period beginning July 1, 2017 and early adoption is permitted. The Company is currently evaluating the newly issued guidance, including the estimated impact it will have on our consolidated financial statements. The Company has not yet determined when the changes will be adopted.
