Bill Overview

Analyzed Economic Effects

2 provisions identified: 1 benefits, 0 costs, 1 mixed.

Credits can be sold; utilities pass value

You may transfer this tax credit to another taxpayer who can use it. The buyer must follow the same rules. If a regulated utility receives the credit, it must pass the value to customers in its next rate case or as the Public Service Commission directs.

25% tax credit for renewable gas equipment

For taxable years beginning after 2025 and before Tax Year 2030, South Carolina gives a 25% tax credit. It covers equipment used only to collect, process, and move landfill gas into renewable natural gas (90%+ methane) for commercial use. Claim it against state income tax or license fees in the year the equipment is placed in service. Costs must be certified by the State Energy Office; eligible costs include engineering and permitting, but not offsite utility work, land, legal or admin costs, or unrelated pipeline expansion. The credit is capped at $5,000,000 per tax year, is nonrefundable, and unused amounts from credits earned before the end of 2030 carry forward 15 years. Apply to the State Energy Office by January 31 for prior‑year placed‑in‑service equipment; the office must respond within 30 days. If operations stop, commercial production ends, or equipment is removed within five years, you must repay a prorated share of the credit.
