Does it matter for Connecticut taxes whether real estate is held in an LP or an LLC?

Why the question arises

An individual acquiring Connecticut real property, or restructuring a holding, usually reaches the LP-or-LLC question from liability and governance planning and wants to know whether the tax system penalizes the choice. In some states it does. California imposes a gross-receipts-based fee on limited liability companies that limited partnerships do not bear, and Texas can treat a passive limited partnership more favorably than a limited liability company under its franchise tax. Connecticut is not one of those states: nothing in its statutes prices the two forms differently, and the analysis below is the same for both.

Classification

The limited liability company answer is statutory. Connecticut General Statutes Section 34-243v provides that a limited liability company formed under the Connecticut Uniform Limited Liability Company Act, or a foreign limited liability company transacting business in the state, shall be treated, for purposes of taxes imposed by the laws of the state or any political subdivision, in accordance with its classification for federal tax purposes. The limited partnership statutes contain no corresponding provision, which is the one theoretical asymmetry between the forms. It has no practical consequence where the federal classification is partnership: Connecticut's tax statutes reach partnerships of every stripe through the same definitions, and a limited partnership classified federally as a partnership is taxed as one. A single member limited liability company disregarded for federal purposes is likewise disregarded for Connecticut income tax purposes, so an individual owner reports the property's results directly.

Income tax obligations

The income tax layer has been rebuilt twice since the era of the old checklists. From 2018 through 2023 Connecticut imposed a mandatory pass-through entity tax on partnerships and S corporations, the only mandatory regime in the country, with an offsetting credit at the member level. For taxable years beginning on or after January 1, 2024, the tax is elective: the entity elects annually, by written notice to the Department of Revenue Services by the due date of the return including extensions, and an electing entity computes the tax at 6.99 percent on a base that excludes income passing to corporate members. The 2024 change also restored the section 12-719 nonresident payment regime that had been suspended from 2018 through 2023. Whether or not it elects, a partnership with nonresident individual partners must make a payment on each such partner's behalf at the highest marginal rate unless the partner's Connecticut-source distributive share is less than $1,000; for an electing entity, that payment is reduced by the partner's pass-through entity tax credit (Conn. Gen. Stat. section 12-719). A nonresident whose Connecticut-sourced income from pass-through entities is less than $1,000 is treated as having only casual, isolated, or inconsequential Connecticut activity, and a nonresident whose only Connecticut-source income comes from pass-through entities generally files no separate return, because the entity's return and its payment on the nonresident's behalf satisfy the nonresident's filing and payment requirements (Conn. Gen. Stat. section 12-719(b)(2)(B)); a nonresident with other Connecticut-source income files under the ordinary rules, including the gross income test ($15,000 for a single filer). Every element of this regime applies to a limited partnership and a limited liability company identically, and for a real estate holding entity with out-of-state owners, the annual election decision, and how much of the nonresident payment the entity-level credit absorbs, is now the recurring compliance question the structure carries.

Transfer taxes

Connecticut reaches transfers of the property and transfers of the entity, and again the entity's form does not matter. A deed transfer bears the real estate conveyance tax, a state tax with rates tiered by property type and price plus a municipal tax, collected at recording. A transfer of the entity rather than the property is not an escape: under Connecticut General Statutes Section 12-638b, the transfer of a controlling interest, more than 50 percent of the capital, profits, or beneficial interest in a partnership or limited liability company, in an entity possessing Connecticut real property valued at $2,000 or more bears the controlling interest transfer tax at 1.11 percent of the present true and actual value of the real property. The seller reports the transfer on Form AU-330, transfers within six months of one another are presumed related, and a change in organizational form with no change in beneficial ownership is exempt, which is the provision that lets an existing holding move between the LP and LLC forms without a transfer tax event when the ownership stays put.

What fell off the checklist

The item most likely to survive on an old checklist is the business entity tax: $250 every other year from limited partnerships and limited liability companies taxed as partnerships, reported on Form OP-424. It is gone. The tax was repealed for taxable periods beginning on or after January 1, 2020, and no filing or payment has been due since. The repeal matters in both directions: it should not appear in a projection of the structure's carrying costs, and its absence from recent years' records is not a compliance gap. For periods before 2020 that remain open in an acquisition diligence or a voluntary disclosure, the obligation was real, applied to both forms alike, and attached to entities required to register with the Secretary of the State whether or not they registered.

Practice notes

Three points organize the analysis. First, let nontax law pick the form: since Connecticut taxes the two identically, the choice belongs to liability, financing, and governance considerations, and to the tax laws of the owners' home states rather than Connecticut's. Second, plan the exit before choosing the path: a sale of the property and a sale of the entity are both taxed, under different taxes with different rates and different filers, and the controlling interest transfer tax's related-transfer presumption reaches staged sales that were structured to stay under 50 percent. Third, calendar the election: for a holding entity with nonresident owners, the pass-through entity tax election is annual, the election changes how much of the nonresident payment the entity-level credit absorbs, and the better answer can change year to year with the owners' other Connecticut income and the deductibility of the entity-level tax federally.
