Because S Corporations and Partnerships have an obligation to get information to their shareholders and partners in a timely manner, the penalties for late filing are steep! If no tax is due, the penalty for filing an S Corporation return late is $210 per month, or portion of a month that the return is late, multiplied by the number of shareholders! For partnerships, that amount is $205 per month or portion of a month multiplied by the number of partners.
An S Corporation with 5 shareholders that files on April 15th will owe $1,050 in penalties. If the return is filed on April 16th, the penalties would be $2,100!
Plus, your state may also impose penalties for being late.
It is very important that your Partnership or S Corporation tax return is filed on time!
