Introduced in 2014, Social Investment Tax Relief (SITR) was designed to encourage investment into social enterprises and charities to support their trading activities. Importantly, SITR fills a gap by providing a subsidy to eligible social enterprises and charities who aren't able to access similar schemes such as the Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS).

For social enterprises and charities

If you provide professional support to charities and social enterprises, SITR may enable the organisations you work with to raise smaller amounts of investment in a more cost-effective way.

For investors

If you provide professional support to individual investors, SITR may be attractive investors who are interested in supporting organisations who have a positive social impact


SITR means investors can look after their hard-earned savings, make financial returns with a tax subsidy, and make a real difference to society by the way in which they invest. What’s not to like?

SITR effectively limits the risk of using your money to invest and address social issues, by reducing the financial impact of any loss, via favourable tax and loss relief treatments.
