The Senate voted 91-4  to extend the highway trust fund authorization through October 29^th from its current expiration date of July 31^st, 2015 and it is not headed to the President for signature.   The bill – H.R. 3236 – contains numerous revenue raising provisions (intended to raise approximately $8 billion in revenue to offset the cost of continued highway spending). Among the other revenue-related provisions, the bill (approved by the House of Representatives on July 29^th) would accelerate the deadline for filing partnership tax returns to March 15 for calendar year taxpayers (or two and a half months after the close of the tax year for fiscal year taxpayers). At present, partnerships have until April 15 (or three and a half months after the close of the tax year) to file returns. The proposed effective date is for returns for taxable years beginning after December 31, 2015. If passed, partnerships may need to scramble to prepare K-1s and file tax returns before the new, accelerated deadline, and ultimately may need to request extensions of time to file.  The maximum extension for partnership Form 1065 is proposed to be a 6-month period ending on September 15 for calendar year taxpayers.
