Hawaii Sales Tax Guide: Understanding the 4% General Excise Tax (GET)

Hawaii, the "Aloha State," offers more than just world-class beaches, volcanic wonders, and a unique Polynesian heritage—it also possesses one of the most distinctive and comprehensive taxation systems in the United States. Unlike most states that use a traditional "Sales Tax," Hawaii employs what is known as the **General Excise Tax (GET)**. For residents, business owners, and the millions of tourists who visit Oahu, Maui, and the Big Island, understanding GET is essential, as it influences the price of almost almost everything in the islands.

1. What is GET? A Tax on the Business, Not the Item

Technically, the **Hawaii statewide General Excise Tax base rate is 4.0%**. However, the legal definition makes it unique: **GET is a tax on the business for the privilege of doing business in Hawaii**, rather than a tax on the consumer.

While the tax is legally imposed on the business, Hawaii law allows companies to pass this cost directly to the buyer as a separate line item. Because businesses must also pay tax on the tax collect if they line-item it, the effective rate passed to the customer is often mathematically adjusted to **4.166%** or higher. In the City and County of Honolulu (Oahu), an additional local surcharge brings the effective rate to **approx. 4.5%**.

Crucially, because GET is a tax on business activity, it is incredibly broad. It applies to **professional services (lawyers, doctors, accountants)**, **commission fees**, and **rent payments**, which are almost almost never taxed in states with a traditional "Sales Tax."

2. Historical Context: Funding the "Aloha State" Infrastructure

Hawaii first adopted its General Excise Tax in 1935 during its territorial days. Since then, it has grown into the primary engine of the state’s fiscal health. Because Hawaii has a small population but manages millions of international tourists annually, the GET allows the state to "export" a significant portion of its tax burden to visitors.

The revenue generated is vital for funding Hawaii’s world-class conservation efforts, its unique public education system (which is managed at the state level rather than locally), and its extensive network of coastal highways and harbor systems. By relying on a broad-based GET, Hawaii is able to maintain its critical infrastructure across eight main islands, ensuring that the spirit of Aloha remains preserved for future generations.

3. Key Exceptions: The "No Relief" Reality on Groceries

Because GET is a broad tax on business activity, Hawaii provides very few of the exemptions found in other states:

• **Groceries**: Unlike many mainland states, **Hawaii taxes groceries and food at the full General Excise Tax rate**. There is no statewide exemption for bread, milk, or produce. This contributes to Hawaii having some of the highest food costs in the nation.
• **Medical Supplies**: Prescription drugs and insulin are 100% tax-free. Many home healthcare services also qualify for exemptions.
• **Non-Profit Fundraising**: Specific exemptions exist for religious and charitable organizations to support the state's vibrant non-profit sector.

4. Use Tax & The "Amazon" Impact

Hawaii is very diligent about its **Use Tax**. If you purchase high-value items from the mainland and have them shipped to Hawaii, you are technically legally required to pay the equivalent GET percentage. With the implementation of "Marketplace Facilitator" laws, nearly all major mainland online retailers now collect Hawaii GET automatically based on the delivery Zip Code. This ensures that Hawaii’s local "mom and pop" brick-and-mortar shops—essential to the island way of life—are protected from being undercut by tax-free e-commerce competitors.
