Resources on SITR for investors

Social Investment Tax Relief is a tax incentive for individuals making an investment into a charity or social enterprise. Individuals making an eligible investment can deduct 30% of the cost of their investment from their income tax liability. It is modelled on the existing Enterprise Investment Scheme.

The maximum investment into an individual organisation is approximately £270,000 over three years. Individual investors can invest up to £1 million and can invest in multiple charities and social enterprises per year.

GET SITR and sizing the market

GET SITR is a campaign to raise awareness of Social Investment Tax Relief so more charities, social enterprises and investors know about it. As part of the campaign, we did a piece of work sizing the market to estimate the number of organisations eligible for the relief. As a headline, we believe there are over 30,000 organisations that could benefit from SITR. But, to date, only around 60 deals have been completed. This tells us that there is a lot more that can be done.

In addition to the market sizing exercise, we are also working on an SITR 'Open Source' database of deals that have taken place. We hope to use this information to improve understanding of SITR. You can also read our blog on the work.

How you can help

If you're interested in contributing to the database and/or have ideas about market sizing you'd like to share with us, please get in touch:
