Do I have to file extension with Hawaii tax separately from federal?

[LeonardS]

No, Hawaii will not accept the federal extension form as an extension for your Hawaii tax return. If you expect to owe income taxes, you should submit your payment with payment voucher Form N-101A.

While the law requires taxpayers to file by April 20, taxpayers are granted an automatic 6-month extension (no form is required to request the extension) to file the return through October 20, 2022 if one of these two conditions is met:

1. The taxpayer is due a refund, or
2. The taxpayer pays the properly estimated tax amount owed by April 20, 2022. Taxpayers who are not able to pay the properly estimated tax amount owed should pay as much as they can to avoid additional interest and penalties.
