I need to know how to add a new tax liability in quickbooks so that it automatically deducts it during payroll processing.

Hello there, @zoesophiebookkee.

To give you the right amount of information, I'd like to ask if what tax liability you're referring to? 

If you're referring to unemployment or local taxes, QuickBooks automatically update the taxes as long as you've set up the address for local taxes correctly.

If you're referring to the withholdings, make sure to check your employee's allowances, status and your employee's details.

However, if you're referring to something else aside from the above mentioned, feel free to add your comment below. Have a good day!

Hi There! Thanks for the help!

So in the state of WA they passed a new law requiring  deducting a percentage off of employees gross wages every pay period and then paid out to the state quarterly. Im unsure how to set this up in the online version. 

Thanks for getting back, zoesophiebookkee.

I can bring some clarifications about your states new tax liability in QuickBooks Online (QBO).

All the payroll updates from your state automatically flows in QBO. Therefore, there is no need for you to set this up.

To make sure we enter the correct tax rate, you can check out this article: Washington Payroll Tax Compliance.

Thank you for the information! So because this new tax law starts is January 2019, is that why I dont see anything in my books currently?

I really appreciate the help :)

Allow me to add some more details about payroll tax updates in QuickBooks Online (QBO).

Payroll tax rates for state and federal taxes automatically updates when there are changes coming from your tax agencies. However, State Unemployment Insurance (SUI) and State Disability Insurance (SDI) rate needs to be manually entered through the Payroll Settings. 

Here's how:

1. Go to Taxes.
2. Choose the Payroll Tax tab.
3. Under Pay Taxes, choose Edit your tax set up.
4. Select the name of the state.
5. Scroll down to the section labeled State Unemployment Insurance (SUI) Setup. Then, click Change or add new rate.
6. Enter your new rate as a percentage from the notice you received from your state.
7. Enter the Effective Date.
8. Click OK.

That's it. Don't hesitate to get back to me if you have other questions about payroll updates. I'll be around to help you out.
