What is the cutoff for contributing to an HSA?
You can contribute to your 2010 HSA until April 15, 2011. But payroll contributions to the HSA will cease after the last pay period in December. However, you can still contribute outside of payroll deductions. Between January 1, 2011, and April 15, 2012, you can make direct contributions to your HSA administrator, up to the annual contribution limit.
