1. What is H.3858? 

H.3858 is a South Carolina law that changes how property taxes are calculated for boats and outboard motors. 

The law: 

• Reduces boat and outboard motor property taxes 
• Eliminates separate outboard motor titles 
• Allows boat and motor taxes to be combined into one bill 

2. When do the changes take effect?

The law takes effect January 1, 2027. 

Tax reductions will be phased in over three years: 

• 2027 tax year – partial reduction 
• 2028 tax year – larger reduction 
• 2029 tax year – full reduction 

3. Are boat taxes being reduced?

Yes. 

When fully implemented, property taxes on boats and outboard motors will be reduced by approximately 50%. 

4. Did the tax rate change from 10.5% to 6%?

No. 

The 10.5% assessment ratio remains in place under state law. 

Instead, the law reduces the portion of the boat and motor’s fair market value that is subject to taxation. This creates a tax effect similar to a 6% assessment ratio. 

5. How does the reduction work?

The law exempts a portion of the fair market value of boats and outboard motors from taxation. 

The exemption increases over three years until: 

• 42.86% of the value is exempt 
• 57.14% remains taxable 

6. Does the reduction apply to both the boat and the outboard motor?

Yes. 

The tax reduction applies to: 

• the watercraft (boat) 
• the outboard motor 

7. Will I still receive separate tax bills for the boat and motor?

In most cases, no. 

The law allows counties to combine the boat and motor into one tax bill. 

8. Are outboard motor titles being eliminated?

Yes. 

Under the new law: 

• Outboard motors will no longer receive separate titles 
• Motor information will instead be associated with the boat registration record 

9. Do I still need to register my boat?

Yes. 

Boat owners must continue to: 

• Maintain current registration with the South Carolina Department of Natural Resources (SCDNR) 
• Pay all applicable property taxes 

10. Do property taxes still have to be paid before registration renewal?

Yes. 

Property taxes must still be paid before a boat registration can be renewed. 

11. What should I do if I replace or upgrade my motor?

Boat owners should ensure their information is updated with: 

• the South Carolina Department of Natural Resources (SCDNR), and/or 
• the County Auditor’s Office 

Accurate reporting is important because separate motor titles will no longer exist. 

12. Why was this law passed?

The law was passed to: 

• Reduce boat property taxes 
• Simplify boat and motor billing 
• Encourage owners to keep boats registered in South Carolina 
• Reduce paperwork related to motor titles 

13. Will this affect local government revenue?

Yes. 

The tax reduction will reduce local property tax revenue over time. The three-year phase-in was included to help counties and local governments adjust gradually.
