Frequently asked tax questions about renewable energy
What are the key tax considerations for a renewable energy project?
Renewable energy investments typically require significant upfront capital, but there are a variety of UK tax incentives available for businesses. Key tax considerations include the following:
- Interest deductibility in the group structure
- Capital allowances
- R&D tax incentives for innovative technologies
- Group and consortium reliefs
- Tax compliance for ongoing operations
- Exit strategies and participation exemptions
- Decommissioning costs and tax accounting
- Irrecoverable VAT and international intragroup transaction structures
- Stamp duty on acquisitions of property, land or shares
What environmental taxes exist in the UK?
There are several environmental taxes imposed in the UK to encourage businesses or users to reduce their environmental footprint:
- The climate change levy (CCL) on energy delivered to non-domestic users
- Landfill tax, which applies to all waste disposed of at licensed landfill sites unless it is specifically exempt
- The aggregates levy on sand, gravel and rock that has either been dug from the ground, dredged from the sea in UK waters or imported
What is the process for making an R&D tax relief claim?
R&D tax relief is claimed through a company’s tax return, assuming it pays UK corporation tax. A claim can be made up to two years after the end of the accounting period in which qualifying expenditure was incurred. However, preparing an R&D claim on a real-time basis tends to increase the value and robustness of the claim, because engineers or developers are more engaged in the process and supporting data is more readily available.
The first step is generally to identify qualifying expenditure incurred on relevant renewable energy projects. Our R&D team includes developers and engineers who fully understand projects at a technical level and can help prepare a technical narrative to accompany the R&D claim. The amount of supporting explanation required depends on the size and claim complexity, but our experts have a high success rate for R&D claims with HMRC.
What costs can my renewable energy business recover VAT on?
Supplies of energy are typically taxable for VAT purposes, so input tax incurred on project costs is often recoverable, subject to the normal rules.
The domestic reverse charge may apply to wholesale gas and electricity supplies, but this depends on the contractual position with customers. It is a complex area of VAT law, but our specialists are happy to help.
