Large employers can now e-file their employment tax returns
Employers who meet the definition of “large employers” now have the option to e-file their employment tax returns (e.g., Forms 940, 941) without the need for a third party.
These large employers are generally required to e-file other returns, such as Form 1120. To do this, they use Form 8453 for the signature, electronically attach it to their tax return, and use their e-file software to file.
Similarly, they may now e-file their employment tax returns. Simply use Form 8453-EMP, Employment Tax Declaration for an IRS E-file Return, for the signature, and electronically attach it to the employment tax return. Then e-file it using the same software used to electronically file other tax returns.
This option is available now, so large employers may use it to e-file their third quarter employment tax returns due in October.
