Because CCS is a non-profit organization, the IRS allows CCS employees to place a portion of their pay in a Tax Sheltered Annuity Plan without paying current federal, state and city income taxes on the amount contributed. Full-time employees, and qualified part-time employees, are eligible to participate on the first of the month following thirty days (30) of employment. CCS contributes 6% of an employees’ gross earnings per pay. Employees may choose to contribute a percentage of their pay on a pretax basis, up to IRS limitations. CCS offers numerous investment funds for employees to choose from. The CCS Tax Sheltered Annuity Plan is administered by TIAA/CREF.
