INDIANAPOLIS (AP) — Indiana residents can now file their 2018 income taxes with the state.

The Indiana Department of Revenue said Monday that it is now accepting tax filings. Officials asked taxpayers to make sure their information is correct and complete before filing “to ensure timely processing.”

DOR Commissioner Adam Krupp says taxpayers should wait to file until they have all of the necessary documentation. He says there’s almost always a delay if taxes are filed without proper documents.

The department also is asking taxpayers to make sure they’re using the correct form, avoiding duplicate filings and filing electronically if possible. DOR says filing online ensures “faster and more accurate returns.

The deadline to file is April 15.
