It is hard to believe we are already halfway through 2019. To be proactive for 2019 tax returns, now is a great time to talk with your accountant or tax preparer to do a paycheck check up or a quick analysis of your profits for self-employed businesses.  This will help in determining if you are having enough taxes withheld on your paychecks for income taxes and if you are making the proper estimated payments for self-employment taxes.
