  • What taxes should be paid when investing in solar power generation projects

    What taxes should be paid when investing in solar power generation projects

    Capital allowances can be crucial to the financial viability of a project. They arise as a result of expenditure on plant and machinery and can be used by taxpayers as a deduction against taxable profits over a period of time. So, on a wind project for example, expenditure on turbines, motors and the like would benefit. There are projects with a high level of debt that may be adversely impacted by the government's proposed changes to the deductibility of interest for tax. EIS is a generous (and complicated) tax regime offering individual investors 30% relief on the total amount invested and a blanket exemption from Capital Gains Tax.
