There are 3 different federal income tax paradigms (Internal Revenue Code Subchapters, C, S & K) governing the income taxation of C Corporations, S Corporations and Partnerships, respectively.
Income Taxation of C-Corporations
A C Corporation (“C Corp”) is subject to “double taxation”. The C Corp pays tax on all of its earned income for the year (the “entity level tax”). Then when the C Corp distributes its earnings (i.e., pays a dividend) to its shareholders (“SH”), the dividend is taxed to the SH,
but the C Corp does not receive a corresponding deduction (“the individual level tax”).
For Example: Ben, the sole SH, invests $10,000 in Corp X. In yr 1, Corp X earns $200,000 and pays $80,000 in income tax (“entity level tax”). Corp X then has $120,000 of after-tax earnings that it distributes to Ben. This distribution is a taxable dividend to Ben and Corp X will not receive a corresponding deduction. Ben will have to report the $120,000 dividend on his personal income tax return and pay approx. 40% tax (“individual level tax”). Ben will only have $48,000 left to spend.
Income Taxation of S-Corporations
S Corporations, (“S Corps”) are gnerally not subject to “double taxation”. S Corporations generally do not pay the entity level tax. When an S-Corp pays a dividend to its SH, the SH is generally not taxed. This results in more value for its SHs.
For example, assuming the above facts, Corp X would not pay any income tax on its earnings of $200,000. Those earnings would flow through to Ben, the SH, and Ben would report the $200,000 on his personal income tax return. Ben would pay $80,000 of personal income tax. Corp X could then pay a dividend to Ben in the amount of $100,000, which Corp X does not receive a deduction, but the $100,000 dividend is generally not taxable to Ben.
S Corps only have 1 layer of taxation.
Income Taxation of Partnerships
Partnerships, including LLCs taxed as partnerships, are similar to S Corps in that they do not incur “double taxation. Partnerhsips only have 1 level of taxation. The income earned in the Partnerhsip flows through to the partners (owners), who in return report the income on their personal income tax returns.
