Here\u2019s everything you need to know about the almost-ignored field of Form W-2; Box D<\/strong>.<\/p>\n

Usually, employers are required to file Form W-2 with the IRS and send a copy of the same to the employee to communicate that the employee compensations have been reported to the IRS for a tax year.<\/p>\n

The filed return includes the relevant social security information to help the IRS track the reports claimed by the employee on their personal income returns as well.<\/p>\n

However, a minute detail within all this filing process, which is almost always ignored, is a little box of Form W-2 called Box-D. The following will discuss in detail the purpose of this box, its reporting obligations, and its uses.<\/p>\n

So, let\u2019s get to it.<\/p>\n

What Is Box-D On Form W-2?<\/h2>\n

Take a look at the IRS Form W-2<\/a> and locate Box-D below the \u201cemployee\u2019s name, business address, and zip code\u201d box.<\/p>\n

Box D is primarily designated for reporting a control number on Form W-2. The box may not always be located in the same place in the W-2 Form as the employers that print out the forms might source the form from a variety of mediums, such as the IRS office, online, or third-party agencies.<\/p>\n

What Is The Purpose Of Box-D On Form W-2?<\/h2>\n

Box D reports the control number, which uniquely identifies your W-2 Form from your employer\u2019s records. This number is usually assigned by your employer\u2019s payroll processing software. You might need this number if you\u2019re trying to import your W-2 form to an eFiling platform like Tax1099.<\/p>\n

It is essential to note that this number is not a mandatory requirement and some employers or their payroll processing platforms may not even assign a control number sometimes.<\/p>\n

However, the presence or lack of a control number is not going to impact<\/em> the accuracy of your reports.<\/p>\n

Uses Of Form Box-D On Form W-2<\/h2>\n

There are no major uses of a control number other than a serial instrument to identify your employer\u2019s W-2 records. The IRS does not mandate the reporting of a control number.<\/p>\n

Your filings will not be impacted by the lack of a control number unless otherwise instructed by the IRS through a communication or notice.<\/p>\n

Taxpayers can leave this field blank as well and continue to report the relevant information to file with the IRS.<\/p>\n
