I'm here to share some insights with you regarding editing contact information in your 940 tax form in QuickBooks Online (QBO) Payroll, Klewis3.
If you haven't filed your 940 form yet, please note that the data on it is derived from your payrolls and company information within QuickBooks Online (QBO). Once prepared using the software, you cannot directly edit or add contact information to Form 940. This form, which reports the annual Federal Unemployment Tax Act (FUTA) tax, automatically uses information from your QBO company settings and payroll data.
For a more detailed guide on filing your final 940 and 941 forms, please refer to this article: Close business and finish payroll tasks.
If you're about to mail your 940 tax form to the IRS, you can refer to this link to learn the different mailing addresses: Where to File your Taxes for Form 940.
Please feel free to reach out anytime if you need assistance with 940 forms or anything else; the QBO Community is here to support you. Thanks for posting and have a great day.
