Understanding Hawaii County’s General Excise Tax: What Every Business Needs to Know

Financial clarity starts with understanding the rules that shape your bottom line. Hawaii’s General Excise Tax (GET) is unique—and for businesses in Hawaii County, the process of collection, deduction, and distribution adds extra layers that can impact your bookkeeping and pricing decisions.

 

How the Hawaii County GET Surcharge Works

 

If you operate in Hawaii County, you’re familiar with the 4.5% GET rate. This includes the state’s 4.0% base and a 0.5% county surcharge. The State collects the surcharge, deducts a 1% administrative fee, and then distributes the balance back to the county each quarter. Funds must be used for county-approved purposes, often tied to infrastructure or transportation.

 

Why Receipts Show 4.712%—The “Tax on Tax” Effect

 

Ever noticed your receipt lists a 4.712% rate instead of 4.5%? That’s because Hawaii’s GET is a tax on gross income—including any tax collected. To avoid under-collecting, businesses are allowed to charge a maximum pass-on rate of 4.712%. This ensures the tax you remit covers both the original amount and the tax on that amount, keeping your books balanced.

 

How is 4.712% calculated? If you simply charge 4.5% on a $100 sale, you collect $4.50, but you owe 4.5% on the full $104.50 (including the tax you collected), which totals $4.70. That leaves you short. To "break even" and cover the tax on the tax, you divide the statutory rate (0.045) by (1 minus the rate):

0.045 / (1 - 0.045) = 0.04712, or 4.712%

So, when you charge $100 x 1.04712 = $104.71, the 4.5% tax on $104.71 is exactly $4.71, matching what you collected. This calculation ensures you remit the correct amount without losing revenue to the tax on tax effect.

 

Key Takeaways for Your Bookkeeping

 

  • Assign income to the correct district: Use "Hawaii" on Forms G-45 and G-75.
  • Understand the deduction: The State retains 1% of the county surcharge for administration.
  • Charge the right rate: You may charge up to 4.712%—never more.
  • Track funds carefully: County funds must be used for their authorized purposes.
