Reclassifying some employee wages to COGS

Thanks for telling me you're using Assisted Payroll, thedjmiked.

You'll have to get in touch with our payroll specialists, since, we're doing the payroll for you. A phone agent will help you reclassify the employees' wages.

Here's how you can contact them:

1. Navigate to our website: https://payroll.intuit.com/support/contact/.
2. Click the Assisted button.
3. Choose Payroll.
4. Click View Contact Info. 

If you have other concerns in the future, you're always welcome to post in the Community. Have a good one! 

"I would like to go back several years and reclassify field techs into a separate COGS payroll account."

Have you looked at the Tax Filings, to see how this was reported?

"would I have to go into each paycheck and reassign the account (if that is that even possible)?"

The Payroll items control the flow of the data to the accounts. First, make sure the historic changes are not going to result in a change to tax filings, requiring amended reporting. Don't make historic changes so casually.
