Corporations Tax Compliance Information

Corporations Tax Compliance Information

Tax Returns and Dates for Corporations.

A stockholder is someone who owns an incorporated business. This may be a Corporation, Limited Liability Corporation, Limited Liability Partnership, a Professional Services Corporation, or a Special Partnership (specific to Puerto Rico).

If you are a the owner of any of these entities, use the information below to help you determine some of the forms that you may be required to file at the federal level (Internal Revenue Service) and state level (Puerto Rico Department of Treasury).

You need to file an Income Tax Return:

As Corporations

As Partnerships

You need to file Estimated Tax payments quarterly:

  • Puerto Rico Business Entities need to file Estimated Tax Payment Vouchers on a quarterly basis. These payments are for income tax estimate payments, while the 1040-ES is for Self-Employment Tax Estimate Payments.

If you the sole proprietor has employees, it must file Form 941, 940 and W-2s at the IRS and W-3s at the Social Security Administration.

If you make payments to other individuals and corporations, you might have to file a 1099 at the IRS or a 480 to the Department of Treasury of Puerto Rico:

If you are selling products and services, you need to file Sales Tax Returns.

Most of these tax returns are due on a quarterly basis, except for the Income Tax Returns, and the W-2, W-3 and Information Returns, which are due annually. While you should verify which dates apply to you and your business specifically, generally the following due dates apply to most taxpayers.

  • US and Puerto Rico Income Tax Returns are due April 15 of every year.
  • Informative Returns are due February 28 of every year. Not the 29th the years that February has 29 days.
  • W-2 Wage and Tax Statements are due January 31 of every year.
