Part I – Pre-Filing Action Items (should be taken care of ASAP when forming your Start-Up)

  1. See attorney – Organize as a LLC in Delaware (or other jurisdiction as advised by your attorney).
  2. See attorney – Execute a LLC operating agreement (necessary in order to designate tax matters partner and to allocate income/loss to individual owners).

  4. Obtain a U.S. Federal Employer Identification Number (EIN).

  6. Register for Business Entity Tax (and if it is listed in the CT application in the future, also choose Pass-through Entity Tax) with CT Department of Revenue Services (DRS).
    Warning – Be careful regarding registering for sales/use tax or withholding tax – you can always add these later when you have CT sales, out of state purchases or begin processing CT payroll.

Part III – Other Common Tax Filings – Review periodically (list is not all inclusive)

  1. Connecticut Sales Tax – Revenue:  When you expect to have sales to CT customers, filing frequency could be as common as monthly.
  2. Connecticut Sales/Use Tax – Purchases: If you purchase products online/out of CT without sales tax charged equal to the CT sales tax rate, you may be subject to Use tax liability in CT. See link above.
  3. Federal and Connecticut Payroll tax filings: Payments to LLC owners for services are reported on Schedule K-1 as guaranteed payments with no tax withholding, similar to a 1099, and thus LLC owners should not be processed through payroll as “W-2 employees.” However, payroll/W-2 applies if you set up U.S. payroll for salaries of non-owners (typically the Federal and State payroll tax filings are handled internally using payroll processing software, or through a 3rd party payroll provider).
  4. Profitable Entities:  Estimate are due to the IRS and State of CT quarterly. IRS estimates will be paid by the individual owners* (based on their expected share of LLC income and other personal situation), while the CT estimates related to LLC income will be paid directly by the LLC.
    1. Information on Federal estimates – Individual level:
    2. Information on CT estimates – Pass-through entity level:

      *For Federal tax estimates paid by the individual owners, the owners need to come up with the funds, so the LLC may need to declare a tax distribution (i.e. taking funds out of the business). The operating agreement should provide legal parameters for the distribution.
  5. Property Tax – If spending significantly on furniture/equipment, consider the applicable property tax rules and contact your town.
