Tax extension for joint return using DirectPay
I’m trying to file an extension online using the extension payment method on via EfTPS / DirectPay as described here. https://www.irs.gov/forms-pubs/extension-of-time-to-file-your-tax-return
my question is, we file joint returns. However during the extension payment it’s only asking for my details and not my spouses. Do I need to do a separate extension for my spouse or does my extension payment automatically also extend the extension to my spouse also. We are still planning to do a joint return after the extension.
