Do I have to make Hawaii estimated tax payments?
Hawaii requires estimated payments once you expect to owe $500 or more in state income tax for the year. The state form is Form N-200V. Payments can be made online through Hawaii Tax Online. Filing and paying federal estimated tax does not cover the state amount — they are separate payments.
Where do I pay Hawaii estimated taxes online?
Hawaii accepts online estimated tax payments through Hawaii Tax Online, run by the Hawaii Department of Taxation. Federal payments go through IRS Direct Pay or EFTPS separately.
What happens if I underpay estimated taxes in Hawaii?
The IRS charges an underpayment penalty based on the amount underpaid and the number of days late. Paying at least 90% of this year's tax or 100% of last year's (110% if your AGI exceeded $150,000) meets the federal safe harbour. Hawaii applies its own interest and penalty on late or short state payments.
State payments are administered by the Hawaii Department of Taxation via Hawaii Tax Online.
