Cash raised during the annual 'wee box' appeal goes towards the organisation's work in Africa, Asia and Latin America and helps some of the poorest people in the world living with hunger, poverty, disease and disasters.
Every year the appeal is taken up by schools and churches across Scotland during Lent.
Thousands of people will give up a favourite treat, like coffee or chocolate, for the 40 days of Lent and put the money saved in their 'wee box'.
The 2016 appeal will be launched on Ash Wednesday, 10th February.
Ministers have confirmed the cash raised by SCIAF between 5th February and 4th May will be matched pound for pound by government funds.
SCIAF's Director Alistair Dutton said: "It's fantastic that we've got UK government Aid Match funding again this year. The donations we get will be doubled - so every £1 you give to the wee box appeal will become £2.
"This will help us give many more people the help they need, such as seeds, farming tools, cattle, training and small loans, so they can work their way out of poverty and have a better future.
"I urge everyone to make the most of this amazing offer and make sure the money you give goes twice as far!"
This year's box features Carfi Sara and his family from Borana in southern Ethiopia.
They lost all their cattle in a severe drought in 2011 and struggled to survive until they were given eight goats and a camel which now provide milk for the family and a source of income.
