Last summer’s highway trust fund extension law* includes a few important federal tax provisions that affect business and individual taxpayers.
Return due dates
The new law accelerates the filing deadline for partnership returns by one month, effective with returns for tax years that begin after December 31, 2015. As a result, the due date for partnership returns will be the fifteenth day of the third month after the end of the partnership’s tax year — March 15 for a partnership with a calendar year.
C corporations will have an additional month to file their returns, generally effective with returns for tax years beginning after December 31, 2015. As a result, C corporation returns will be due by the fifteenth day of the fourth month after the end of the tax year (by April 15 for a C corporation with a calendar year). The extended deadline doesn’t take effect until tax years beginning after December 31, 2025, for C corporations with fiscal years ending on June 30.
For federal estate-tax purposes, property included in the gross estate is generally valued at its fair market value on the decedent’s date of death. That same fair market value then becomes the property’s income-tax basis in the hands of the person who acquires the property from the decedent.
The new law doesn’t change this rule. However, it requires the executor of any estate required to file a federal estate-tax return to furnish an information statement to the IRS and to each person receiving property from the estate. The statement must show the value of the property as reported on the return (and any other information the IRS may require). There are penalties for failure to file and for tax understatements resulting from inconsistencies in basis reporting.
Mortgage information returns
Under the new law, mortgage lenders must include additional items, such as the amount of principal outstanding at the beginning of the year, on information returns required to be furnished after December 31, 2016.
