The Old Age Security pension (or OAS or OAS-GIS) is a taxable monthly social security payment available to most Canadians 65 years of age or older with individual income less than $114,815. As of January 2016, the basic amount is $570.52 per month. At tax time, recipients with a 2014 income of over $71,592 must pay back a portion of their Old Age Security at a rate of 15% of net income. This is often referred to as the "OAS clawback". OAS amounts are indexed to the Canadian Consumer Price Index and are adjusted (generally, increased) four times per year.
