Letter to Taxpayers About Filing an REG-1


This letter contains important information concerning the new Connecticut State Income Tax.

Therefore, you are required to withhold income tax from your employees' earnings.

Please complete the enclosed Application For Tax Registration Number (REG-1) and return it in the envelope provided. (Since we are identifying taxpayers to receive these mailings through several different means, you may receive or may have received another copy of this application.

After we process your registration application, we will send you a Tax Registration Number, detailed instructions regarding your responsibilities to withhold income tax and payment coupons to file when you remit the tax withheld.
