The following changes will be reflected on the July 2025 Solid Waste Tax return, due August 20, 2025:
  • All Solid Waste Tax accounts will be automatically converted to a monthly filing frequency.
    • ​The SCDOR will send an additional MyDORWAY web message to all Solid Waste Tax account holders not currently filing monthly returns.
  • Used tires are now subject to the Solid Waste Excise Tax of $2.00 per tire.
    • Previously only new tires were subject to the tax.
  • The 3% administrative collection allowance has been eliminated for tires only.
    • This deduction was automatically calculated when filing your Solid Waste Excise Tax Return on MyDORWAY.​
    • The 3% administrative collection allowance still applies to lead-acid batteries, white goods, and motor oil and similar lubricants.
  • The $1.00 per tire credit for tires recycled by a qualifying recycling facility has also been eliminated.
    • ​This credit was claimed on Line 2 of the Solid Waste Excise Tax return.
  • These changes are the result of the passage of S. 171.

​Frequently asked questions

Who is liable for collecting and remitting the tax?

A wholesaler or retailer liable for the Solid Waste fee may increase the price of an item by the Solid Waste Excise Tax. Such an increase is considered an increase in the price of the item and not a payment of the solid waste excise fee by the purchaser. There is no requirement in the law that the fee be passed on to the purchaser, and the fee is still due by the wholesaler or retailer, even if the purchaser refuses to pay the fee. Tire retailers, lead-acid batter retailers, motor oil wholesalers, and white good wholesalers need to file. 

What is meant by the term "wholesaler" for Solid Waste Tax?

Wholesalers include anyone who makes sale for resale including a manufacturer, distributor, importer, supplier, jobber, or wholesaler of motor oil and similar lubricants or white goods.

What evidence must retailers or wholesalers obtain from their wholesaler or suppliers to verify to the SCDOR that Solid Waste Excise Tax has been paid?

The retailer or wholesaler must have evidence on their invoice indicating the tax has been paid by their supplier. Evidence would include a supplier's stamped or written statement on the invoice indicating that Solid Waste Tax had been paid.

Is the Solid Waste Excise Tax imposed on new tangible personal property which contain motor oil, tires, white goods, or batteries, such as vehicles, boats, machines, mobile homes, and tractors?

No, the tax is not imposed on the sale of tangible personal property containing motor oil or similar lubricants, tires, white goods, or lead-acid batteries. However, it is imposed on the separate sale of oil, tires, white goods, or lead acid batteries as a replacement part or a repair to vehicles, machines, and the like.

Are sales made to the federal government, or agents of the federal government, taxable?

Yes, Solid Waste Tax is imposed on the wholesaler or retailer, not the purchaser, except for ex-tax motor oil. Therefore, the Solid Waste Fee is not a direct tax on the federal government, and there is no requirement the fee be passed along to the consumer (government). 

NOTE: The federal government will not be liable for Solid Waste Tax imposed on ex-tax motor oil and similar lubricants they import into South Carolina.

Is the tax imposed on consignment sales​?

Yes.

Is Sales Ta​x computed after the Solid Waste Excise Tax is added to the sales price​?

No, Solid Waste Excise Tax is not included when computing Sales Tax. This includes the refundable deposit when a lead-acid battery core is not returned to a retailer.

Is the Solid Waste Excise Tax imposed on sales of lead-acid batteries and white goods?

The tax is imposed only on sales of new lead-acid batteries and new white goods.

What tire sales are subject to Solid Waste Excise Tax​?

The statute imposes the tax on motor vehicle, trailer and motorcycle tires as defined in SC Code Section 56-3-20(2), (4) and (13). The definitions are:

(2) Motor vehicle - Every vehicle which is self-propelled, excepts mopeds, and every vehicle which is propelled by electric power obtained from overhead trolley wire, but not operated upon rails;
(4) Motor-driven cycle - Every motorcycle, including every motor scooter, with a motor which produces not to exceed five horsepower.
(13) Trailer - Every vehicle with or without motive power, other than a pole trailer, designed for carrying persons or property and for being drawn by a motor vehicle and so constructed that no part of its weight rests upon the towing vehicle.

Based upon the above definitions, the types of tires that are subject to the tax are new and used tires sold or leased for transportation of tangible personal property or persons on the streets or highways. Farm tractor tires, airplane tires, off highway machinery, recaps, retreads, lawn mower tires, and tires for vehicles propelled solely by human power, such as bicycles, garden carts, and wheelbarrows are examples of tires that are not subject to the Solid Waste Excise Tax.

Are tires or batteries sold to an automobile dealer or leasing company for a used vehicle that will be leased or ultimately sold subject to the tax​?

Yes, the automobile dealer will be liable for Solid Waste Excise Tax at the time the tires and batteries are withdrawn from their stock for installation on the used car.

What are examples of motor oil and similar lubricant subject to the tax?

Examples of motor oil and similar lubricants subject to the tax include automatic transmission fluid, oil additions which are not burned or consumed in the engine, and jet engine oil. 

Items such as brake fluid, WD-40, hydraulic fluid, 2-cycle oil mixed with gasoline that is consumed or burned, and motor oil or lubricants used in electric motors are examples of items not subject to the tax.

How is the fee computed on parts of a gallon of oil?

The amount of motor oil and similar lubricants subject to Solid Waste Excise Tax should be totaled at the end of the reporting period. When the total results in a fractional gallon, the total should be rounded up to the nearest whole gallon when the fraction is one-half gallon or more and should be rounded down to the nearest whole gallon if the faction is less than one-half gallon. 

For example, if total motor oil sales in South Carolina for the month are 1000.75 gallons, then the amount shown on the Solid Waste Excise Tax Return should be 1001 gallons. Remember, only whole gallons should be reported on the return.

How will exchange or warranty items be treated?

The tax will not be due when there is a full refund or exchange of the item. If there is a pro-rated or partial charge for the item, the tax will be due.

Are replacement parts for white goods, such as compressors, subject to the Solid Waste Excise Tax​?

No. The fee is imposed on the sale of the new item and not on replacement or repair parts. For example, a central heating and air conditioning unit is subject to the fee; however, the replacement of a compressor on an air conditioner is not subject to the fee.​

Are taxpayers who are exempt from Sales and Use Taxes also exempt from the Solid Waste Excise Tax​?

No, the Sales and Use Tax exemptions provided to farmers, manufacturers, and others do not exempt them from Solid Waste Excise Tax.

Is motor oil to be exported from South Carolina exempt from the Solid Waste Excise Tax?

Any person purchasing motor oil or similar lubricants at wholesale in its original package or container and who exports such motor oil or similar lubricants from South Carolina may certify in writing to the seller that the motor oil or similar lubricants will be exported, and such certification, if taken by the seller in good faith, will relieve the seller of the fee otherwise imposed. The written certification should include any documentation to identify the number of gallons exported, such as sales invoice or delivery ticket.

What is the "for hire motor carrier" exemption?

An exemption from the Solid Waste Excise Tax imposed on motor oil and similar lubricants is provided for in the law to "for hire motor carriers" who purchase lubricating oils not for resale for use in their fleets. The for hire motor carrier must hold a Certificate of Public Convenience and Necessity or be registered with the Public Service Commission and must also (1) have a maintenance facility to service their own fleets and properly store waste oil for recycling collections, (2) have reported to the EPA the existence of storage tanks for waste oil storage, (3) maintain records of the dispensing and servicing of lubrication oil in the fleet vehicles and (4) have a written contractual agreement with an approved waste oil hauler. Qualifying carriers must apply for this exemption on using an Application for Certificate (ST-10). Upon approval, exempt carriers will be issued a South Carolina Exemption Certificate (ST-9).
