New Forms

  • Connecticut Composite Income Tax Return and Addendum (CT-1065/CT-1120SI) – For entities submitting a composite income tax return

    • Application for Extension of Time to File Connecticut Composite Income Tax Return and Addendum (CT-1065/1120SI EXT)

  • Connecticut Pass-Through Entity Tax (CT PET) – For entities electing to pay optional pass-through entity tax.

    • Application for Extension of Time to File Connecticut Pass-Through Entity Tax Return (CT-PET EXT)

Tax Law Changes

  • Income tax

    • The 3% rate on the first $10,000 earned by single filers and the first $20,000 by joint filers will drop to 2%, and the 5% rate on the next $40,000 earned by single filers and the next $80,000 by joint filers will drop to 4.5%.

    • The CT EITC has increased to 40% of the federal EITC amount. The maximum CT EITC investment has increased from $11,000 to $11,600.

  • Personal income tax – 25% of section 168(k) federal bonus depreciation can still be added back for four preceding years.

  • Pass-Through Entity Tax

    • Legislation makes the pass-through entity tax optional. Starting with taxable years commencing on and after January 1, 2024, any entity that elects to pay such tax must give the Commissioner of Revenue Services written notice for each tax year it makes the election and must do so no later than the due date (or extended due date) for filing the return. The legislation also makes the following changes to the pass-through entity tax:

      • Eliminates the standard base method and instead requires all entities electing to pay the tax to use the alternative base method.

      • Requires that the pass-through entity file an income tax return and pay the tax on behalf of any nonresident member for whom the business is the only source of Connecticut income.

      • Eliminates the credit against the corporation business tax for pass-through entity tax paid by an entity on behalf of a corporation that is member of said entity and that is subject to the corporation tax.

      • Eliminates the option for a pass-through entity to file a combined return with one or more commonly-owned pass-through entities.

  • Form CT-706/709 — Total annual exclusion for gifts has increased from $17,000 to $18,000.
