Tax filing season for calendar year 2020 opens February 12, a few weeks later than usual. Unlike last year, when the deadline to file and pay any tax owed was extended to July, this year, we revert to good ol’ April 15, so it’s time to get organized. If you didn’t learn the lesson of electronic filing last year, this is the year to dump the paper. Those who had electronic files with the IRS got stimulus checks faster than paper filers. To make.
