How do I post the money payroll paid for child support?

Don't use Bills; this is not your vendor and this is not a Bill to be paid later. You, the employer, are handling that employee's share of Taxes and Child Support, because the employee will not be paying it out themselves. None of this is a Bill to a vendor name. It's all part of Payroll Liabilities.

Thanks for linking to an older article; it's nice to know they still exist and still apply :)

"would I pay the bill under ads with Child Support Garnishment as label?"

Child Support divisions or enforcement is not sending you a Bill to Pay Later. AP is not involved. The Child Support is already deducted from Net Take home.

There is no Bill in this process.

Let's take One Example:

Joe is supposed to get $300 takehome, so enter everything as usual.

Now, Job also has $50 to go to child support. You didn't not state if You sent that or ADP sent that. It Doesn't Really matter, because it is a Diversion or further allocation of Joe's $300:

Joe got $250

Child Support enforcement gets the other $50

Hi there nadeen,

I'm here to help you account for child support. 

Since the garnishment isn't an employer's expense, it will be posted to your liability account. In addition to this, I've found a helpful answer that was previously posted by our awesome Community AllStar qbteachmt: https://community.intuit.com/questions/826439

This should help you input your child support to the correct account. If you have any questions, feel free to leave a comment below. I'll be here to help.

"I still don't know where or how to enter the $50 that enforcement gets"

You seem to be using a Bill for payroll, instead of a Check? What do you list on that Bill? We don't know what your Input looks like.

And who sends the child support payment?

It took me a while to figure out how to do it as it was not obvious.  I had to do a wage levy (in my case for taxes for a particular employee).  I followed steps here to create the wage levy to reduce the check  in the payroll.

After that was done, in order to pay out the levy collected,  I created a check to the Name of the agency setup in the payroll garnishment item (where the money would go - for me this was the MA dept of Revenue).  In the account field for the check, I typed in payroll liabilities  - Quick books picked this up and brought me to a screen where i could chose to 'Pay Payroll Liabilities'. I then selected the appropriate liability account  that I had set up in the payroll garnishment item.

Hope this helps!

I have a third party for payroll. They deduct the child support from the employee and pay it to the state. My bank sends this as a separate payroll expense from the actual payroll, taxes and monthly cost. Do I need to do anything at all or just list it as payroll expense like the others?
