If you were one of the more than 13 million people who obtained a filing extension for your personal 2013 income tax return and have not yet filed, today is the deadline for getting it in; you can still e-file the return. No additional extensions will be granted. If you fail to file by today, you will owe a late filing penalty. For self-employed individuals, today is the last day to fund a qualified retirement plan. Plans must have been set up by the end of 2013 to accept contributions for that plan year. Exception: You can set up and fund a SEP plan before the end of today if you are filing your 2013 return today.

Don’t forget … for year-round tax planning and critical business strategy, you’ll want your copy of J. K. Lasser’s Guide to Self-Employment: Taxes, Tips and Money-Saving Strategies for Schedule C Filers - available on Amazon now!
