All Americans know that filing a tax  return is important, but for many business owners it is even more important  to keep their business thriving. Therefore, some business owners like  Sabina Gault of Los Angeles have decided to request a tax deadline extension  in order to focus on operating her business. The Wall Street Journal  wrote a great piece on some great reasons to file an extension, and  the precautions to take when doing so. I have included a segment of  their helpful article below. 
At Sabina Gault's Los Angeles communications  firm, Konnect PR Corp., the business day never ends. Ms. Gault and her  staff of four regularly work nights, weekends—anytime—promoting  the firm's 13 clients. With her mind so occupied, filing taxes for her  company gets pushed to the end of her to-do list.
 
"Payroll and insurance and all of  the legal bills—those go out every month," Ms. Galut says. "But  with taxes…the next thing you know, it's April 10."
 
Recognizing she'd have to tackle a significant  amount of paperwork before she could send Konnect's tax documents to  her accountant, Ms. Gault decided to file for an extension. "We  need to go through all expenses and it will take two or three weeks  to get that together," Ms. Gault explains. The extension, which  took less than two hours to file, will give Ms. Gault an additional  six months.
Filing for an extension is a common way  for business owners to buy some time during tax season. While extensions  do not defer payment to a later date, they permit business owners to  estimate what they owe and pay based on that estimate. Then, they can  use the additional time to gather and organize all necessary paperwork  for their actual tax return, which they file along with a check for  the remainder of what they still owe—if their bill is more than they  estimated.
Small business owners can receive an  extension by filing IRS form 4868 for sole proprietorships or form 7004  for C-Corps, S-Corps and partnerships. These forms grant an automatic  six-month extension for all entities except partnerships and corporations,  which are granted a five-month extension.
