Where to mail form 5558

Form 5558, "Application for Extension of Time to File Certain Employee Plan Returns", is typically filed with the Internal Revenue Service (IRS) at the following address:

Internal Revenue Service Attn: Form 5558 1111 Constitution Ave NW Washington, DC 20224-0002

However, it's always a good idea to check the IRS website or the instructions for Form 5558 to confirm the correct mailing address, as it may be subject to change.

Additionally, you can also file Form 5558 electronically through the IRS's online system, the Electronic Federal Tax Payment System (EFTPS). To do so, you'll need to create an account and follow the instructions provided.

It's also important to note that you should keep a copy of the filed form for your records, as the IRS may request it if there are any issues with your application.
