What are the contribution limits for HSA?

For 2015, health savings account contribution limits are $3,350 for individual coverage and $6,650 for family coverage, according to Optum Bank. These limits are set by the Internal Revenue Service each year and include both employee and employer contributions, according to the Society for Human Resource Management.

Contributions for the previous year are allowed until the tax filing deadline for that year, which is generally April 15 of the following year, according to Optum Bank. Contributions that exceed the allowed maximum must be counted as taxable income and are taxed at 6 percent. HSA rules also allow catch-up contributions at a maximum of $1,000 per year, according to the SHRM.
