Do think we could use Box 14?  

There are also rules about salaried employees reporting the overtime; some quality, some do not.  As the accountant, I don't want to get into the weeds between firefighters and software engineers about who qualifies.  

The rules state the employee must take the number provided by the employer.  When I submit W-2s in QB PR, there is not an attachement feature I am aware of to provide the supporting statement.  Maybe the taxpayer can attach the supporting document to their own tax return.  

I'm hoping there won't be some taxpayer revolt early April when this hasn't been settled and they try to file.
