Taxpayers donating to help earthquake-hit Haiti can top-up their contributions without having to shell out any extra cash.
The gift aid scheme, which applies to most forms of charity-giving, allows good causes to get tax relief on your contributions to add to their pot, if you're a UK taxpayer.
A £50 donation from you via this mechanism means the charity gets £64 (see the Charity Giving guide).
Martin Lewis, MoneySavingExpert.com founder, says: "If you're moved by the Haiti tragedy, donations make a real impact. UK taxpayers should always remember to donate by gift aid. Whilst our economy is struggling, the poverty in Haiti is in a different league and this disaster has compounded it.
"Yet don't force your finances if you can't afford it, you are better getting them in shape so you can donate in future. Even if you can only afford a pound, why not get together with friends and work colleagues to make a joint donation?"
Tens of thousands of people are thought to have been killed in the devastating earthquake that struck on Tuesday night (UK time). In total, the disaster is thought to have affected three million people.
Higher rate (40%) taxpayers can reclaim the difference between the basic and higher rates on top of this – another £12.50 on a £50 donation – via their self assessment tax return or a P810 form from their tax office.
