Remember: Proper maintenance throughout the year makes tax season painless and protects your corporate liability shield.

PENALTIES TO AVOID

  • Late Statement of Information: $250+ penalty
  • Late franchise tax payment: Penalty + interest (compounds quickly)
  • No annual minutes: Potential piercing of corporate veil
  • Missing tax filing: $195+ per month late, per shareholder (S-Corp)

Bottom line: Stay on top of these simple requirements and you'll never pay unnecessary penalties.


Anyone may arrange his affairs so that his taxes shall be as low as possible; he is not bound to choose that pattern which best pays the treasury. There is not even a patriotic duty to increase one's taxes. Over and over again the Courts have said that there is nothing sinister in so arranging affairs as to keep taxes as low as possible. Everyone does it, rich and poor alike and all do right, for nobody owes any public duty to pay more than the law demands.
