How can I update our pay schedule?

Hello there, @andrea13.

I'd be glad to help you sort things out. If you're referring about changing he payment frequency for sales tax for the Old Sales Tax Center view, we can filter the amounts owed and enter the tax period ending when recording the payment.

Here's how:

1. Go to the Taxes menu.
2. In the Sales Tax Center, click the Show By dropdown, then select among Month, Quarter, Half-Year or Year.
3. Click the Record Tax Payment.
   
4. Enter the necessary information and the tax period ending.
5. Click Record Tax Payment.

Meanwhile, if you're using the new Automated Sales Tax, you can change the payment frequency through the Sales tax settings.

1. Go to the Gear icon.
2. Select Payroll settings.
   
3. Under Taxes, choose a tax schedule that you want to update. (In my screenshot, I selected Federal Taxes).
   
4. Click Change or add new schedule.
   
5. Once done updating, click OK.
