Why So Many Deadlines Now?
According to tax experts the IRS management is compressing the timeline with an eye towards optimizing the processes in the best possible way, despite it causing numerous issues to arise. This will mean they can concentrate on core services better. Additionally, it will allow the IRS to have time to communicate with the staff better about the restructuring of the services thus improving and changing the scope of the services in this way.
Due to the fact that formerly, the important date was the 15th of April, it could be said that the taxpayers are in a problematic situation now, as in the event of the most taxpayers would forget for the monthly due rates. This was the opinion of some taxpayers, but the answer given by the IRS itself shows a different truth.
What Happens If You Miss One?
What If you are late for the smallest IRS deadline, you can be penalized. The four most likely penalties are:
- filing late (up to 25%)
- paying late (0.5% per month)
- taxes unpaid will attract daily interest
What You Should Do Next
- Print out the monthly calendar of deadlines.
- Set reminders on your phone or calendar.
- Ask a tax professional to help you out if you are not sure of what applies to you.
In addition, keep in mind, the IRS will not call you if you’re late but they will notice.
