A single filer taking the standard deduction, this work as the only income, the calculator above handles the other filing statuses.

Selling into and out of Hawaii
Income tax follows you: Hawaii taxes your profit wherever the buyer was. Sales tax does not. Marketplace facilitator laws make the platform collect and remit sales tax on your behalf in most states, which is why a seller can have customers in all fifty and still file only one income tax return. Selling off-platform is where that stops being true.

Marketplace seller tax questions in Hawaii
How much should a Hawaii seller set aside?
About 7.8% of gross on the $45,000 example, $3,496 across self-employment tax, federal income tax and $854 to Hawaii. Set aside from each payout rather than finding it in April.
Does the $45,000 on my 1099-NEC match what Hawaii taxes?
No. Hawaii taxes profit, not gross. After $26,775 of deductions the taxable figure is $18,225, so the Hawaii bill is $854 rather than what gross alone would suggest.
