Division of Revenue Director Patrick T. Carter has announced that Delaware tax season filing deadline this year is Monday, May 2, 2016. Citizens are encouraged to file their 2015 State of Delaware Personal Income Taxes or file an extension to Monday, October 17, 2016 by using online services at www.delaware.gov.
For paper-filed returns, the State uses a modernized processing system that identifies tax filings based on the type of return, i.e. refund or balance due. Any taxpayer who files a 2015 tax return using a previous-year return, or who modifies the paper return in some way will experience significant delays. Paper tax returns are available for download at www.revenue.delaware.gov.
Because Delaware does not maintain reciprocal agreements with other states, it is important for anyone who is not a Delaware resident – but who has worked in Delaware – to file a Delaware tax return. Delaware residents who work out-of-state are required to file returns with Delaware in addition to the state where they worked.
By law, Delaware employees should receive their W-2 employment forms by January 31, 2016 for any job worked during the 2015 calendar year.
