In our past blog post, IRS Notices Decoded: What Your IRS Notice Means we reviewed the reasons you may have received a notice from the IRS, advised how you should move forward, and provided a list of common IRS notices with their definitions. Since it’s tax season we decided to one-up ourselves and provide you with the whole IRS notice list. Not only is this the complete list, it includes Spanish versions of the IRS notices as well.
If you have received an IRS notice and are searching for answers, this complete guide will help you find the information you need (use Control+F or Command+F to locate your notice). It is also always a good idea to seek advice from a licensed Tax Attorney or Tax Accountant to advise you about the best way to handle your situation. An experienced tax attorney will represent you to the IRS and relieve the unwanted burden of dealing with the case by yourself. At Boxelder Consulting we understand how stressful it can be if you’ve received a notice from the IRS, and are always here to help.
