To the extent you wish to engage our firm to apply for extensions of time to file tax returns on your behalf, you must notify us of this request in writing. Our firm will not file these applications unless we receive an executed copy of this Agreement and your express written authorization to file for an extension. In some cases, your signature may be required on such applications prior to filing. Failure to timely request an extension of time to file can result in penalties for failure to file tax returns, which accrue from the original due date of the returns and can be substantial.
