1031 Exchanges in Connecticut: Rules, Taxes, Insurance, and the Long Arc

A Shop 1031 research page. Reviewed 2026-06-03. Every claim sourced; sources collected at the foot of the page.

Connecticut is a high-cost conforming state with a graduated conveyance tax that does not exempt §1031 exchanges, not a low-friction transactional state. The distinction matters because the Connecticut conveyance tax stacks state and municipal components at every recording, and unlike Form 593 in California or IT-2663 in New York, a properly executed §1031 exchange does not relieve the seller of the Connecticut conveyance tax obligation on the relinquished close. Connecticut conforms to federal §1031 through Connecticut General Statutes §12-700 et seq. and taxes recognized boot at the graduated state rate topping at 6.99 percent. Property tax effective rates run among the highest in the country. Each of these is independently sourceable.

This page is the working guide. The federal §1031 floor, Connecticut’s full conformity, the state-and-municipal conveyance tax stack that does not exempt §1031, the property-tax structure, the post-Sandy coastal insurance dynamics, the demographic trend, and the unique considerations a Connecticut exchanger should clear before identifying replacement.

§1. 1031 mechanics in Connecticut

The federal floor applies in Connecticut the same way it applies in every other state. 26 U.S.C. §1031 and 26 C.F.R. §1.1031(k)-1 establish the deferral framework, with the 45-day identification and 180-day exchange windows. ^{1 2}

Connecticut fully conforms to the federal §1031 treatment at the state income tax level. The conforming provision is in Connecticut General Statutes §12-700 et seq., which computes Connecticut adjusted gross income by reference to federal adjusted gross income with state-level modifications that do not include a §1031 modification. A properly executed exchange that defers gain federally defers it for Connecticut income tax purposes at the same time. Recognized boot is taxed at the Connecticut graduated rate, with the top marginal bracket at 6.99 percent. There is no separate Connecticut capital gains rate. ³

The Connecticut conveyance tax under Connecticut General Statutes §12-494 is the operative state-specific cost at every Connecticut closing. The state tax is graduated: 0.75 percent on consideration up to $800,000, 1.25 percent on consideration between $800,000 and $2,500,000, and 2.25 percent on consideration above $2,500,000. Municipalities impose an additional local-option conveyance tax of 0.25 percent (most municipalities) or up to 0.50 percent in eighteen targeted municipalities under separate authority. On a $5,000,000 Connecticut commercial acquisition, the combined state-plus-municipal conveyance tax runs approximately $99,000, depending on the municipality. Connecticut does not provide a §1031 exemption from the conveyance tax; the full consideration is subject to tax even when no cash changes hands. The grantor (seller) is statutorily responsible. ^{4 5}

Connecticut imposes no state-level registration or bonding regime on Qualified Intermediaries. Federal §1031 rules apply. The buyer should confirm independently that the QI carries fidelity bonding and errors-and-omissions coverage proportionate to the transaction size.

Connecticut is an attorney-state for real estate closings. Both buyer and seller typically engage Connecticut-licensed counsel, and counsel attends the closing. Title insurance is issued through Connecticut-licensed agents.

§2. Property tax in Connecticut

Connecticut has an effective property tax rate of approximately 1.79 percent of owner-occupied housing value, among the top five highest in the country. The structural mechanics are governed by Connecticut General Statutes Title 12, Chapter 203, with assessment administered at the municipal level by town assessors. Connecticut property is assessed at 70 percent of fair market value, with revaluation cycles set at five years under §12-62. Mill rates are set by each municipality and applied to the 70 percent assessed value. ⁶

For an exchanger acquiring Connecticut commercial property, the 70 percent assessment ratio is the operative number. Mill rates vary materially across Connecticut’s 169 towns, with the highest rates in cities (Hartford, Bridgeport, New Haven, Waterbury) and lower rates in wealthy suburbs (Greenwich, Darien, New Canaan, Westport). Cap rates compress in markets with structurally lower mill rates; the property-tax-adjusted yield is a more honest comparison than the nominal cap rate.

Harlow’s note on unit economics. On a $5,000,000 Connecticut commercial acquisition at the state-average effective rate, year-one property tax runs roughly $90,000 annually. The geographic dispersion across municipalities is wide enough that the same property at the same fair market value could carry a 2x tax bill in Hartford versus Greenwich. Build the hold-period line from the specific town’s mill rate applied to the 70 percent assessment ratio.

§3. Property insurance in Connecticut

Connecticut property insurance carries coastal hurricane and nor’easter exposure on Long Island Sound and inland severe-weather exposure across the state. Hurricane Sandy (2012) reset the carrier market for coastal Fairfield and New Haven Counties; subsequent storms have reinforced the repricing. The Connecticut Department of Insurance regulates carrier conduct. There is no Connecticut FAIR Plan equivalent for residential property; the Connecticut Fair Plan administered by the Connecticut FAIR Plan Association provides a residual market mechanism for property in designated areas. ⁷

For an exchanger acquiring Connecticut coastal commercial property, the binding-quote discipline used in Florida and the Carolinas applies. Named-storm deductibles, flood-zone determinations, and excess-flood layering above NFIP caps are standard. Inland commercial property runs more functional with private-market underwriting.

Harlow’s note on unit economics. For a $5,000,000 Connecticut inland commercial property, expect property-insurance expense in the range of 0.4 to 0.8 percent of insured value. For coastal Fairfield or New Haven County property, the range can run 0.7 to 1.5 percent, with separate excess flood adding 0.1 to 0.3 percent. Bind from a quote, not a national-average assumption.

§4. Demographic trends

Connecticut’s population stood at approximately 3.6 million as of 2025 Census estimates, with roughly flat year-over-year change. Net domestic migration to Connecticut has been negative for most of the past decade, with outflow to Florida, the Carolinas, and other lower-cost markets. International migration provides positive offset. Natural increase has slowed. The state’s median age is among the higher among states. ^{8 9}

Median household income in Connecticut was approximately $93,000 in 2024 per Federal Reserve-published Census American Community Survey estimates, materially above the national median. Geographic concentration is sharp, with Fairfield County clustering well above the state median and Hartford and New Haven Counties below. ^{10 11}

The major Connecticut metropolitan markets relevant to 1031 exchangers are the Hartford-East Hartford-Middletown corridor (approximately 1.2 million population), Bridgeport-Stamford-Norwalk (the Fairfield County corridor, approximately 940,000), New Haven (approximately 860,000), and the Stamford-Greenwich submarket which functions as part of the New York metropolitan area. Each carries a distinct asset-class profile. Fairfield County concentrates institutional office and high-end multifamily with the deepest New York-spillover bid; Hartford is the deepest balanced market across asset classes including office, multifamily, and industrial; New Haven serves the biotech and Yale corridor; the inland suburban markets concentrate small-bay industrial and grocery-anchored retail.

§5. Unique legal and financial considerations

The first is the conveyance tax on §1031 exchanges as discussed in §1: there is no §1031 exemption from the Connecticut conveyance tax. The disposition-side modeling on any Connecticut relinquished close should include the conveyance tax in the seller’s net.

The second is the high cost of property at acquisition in Fairfield County. The structural cap-rate compression and the proximity to the New York buyer pool produce institutional bid that does not pencil under conventional underwriting on transitional or value-add property. Exchangers acquiring Fairfield County replacement should use the Shop 1031 normalized cap rate and Dark Shell Score for cross-checking the headline OM number.

The third is the Connecticut Transfer Act, codified at Connecticut General Statutes §22a-134 et seq. The Transfer Act imposes disclosure and remediation obligations on the sale of properties classified as “establishments” (typically commercial or industrial properties with historical environmental conditions). The Act has been substantially reformed but remains operative for certain transactions, and counsel review is appropriate for any acquisition of older industrial or service-station property. ¹²

The fourth is the municipal personal property tax. Connecticut continues to tax certain business personal property at the municipal level, which can affect operating expense underwriting on commercial property with substantial FF&E (hotel, hospitality, retail). The Connecticut Department of Revenue Services publishes guidance.

§6. Closing summary and the work ahead

The Connecticut 1031 exchanger is operating in a market with a clear set of distinguishing features. The federal floor applies; Connecticut fully conforms at a graduated rate topping at 6.99 percent; the conveyance tax stack at recording does NOT provide a §1031 exemption; property tax effective rates run among the highest in the country with material geographic dispersion across 169 towns; insurance exposure is concentrated on the Long Island Sound coast and inland severe weather; demographic growth is roughly flat with negative net domestic migration offset by international; the Connecticut Transfer Act applies to certain commercial and industrial transactions; municipal personal property tax adds to operating expense. None of these is a reason to avoid a Connecticut exchange. Each is a reason to underwrite one carefully. The jurisdiction-specific factors above are starting-point context. A state-experienced CRE professional will translate them into deal-specific judgment.

This is the question Shop 1031 was built to compress. Every Connecticut offering memorandum on the platform is normalized to a single schema, underwritten at re-let to the buyer’s specific equity, debt, and DSCR floor, and ranked by Dark Shell Score. For a market with Connecticut’s specific overlay, that compression is decisive because the variables that move outcomes (conveyance-tax absence-of-exemption on disposition, municipal mill rate selection, coastal insurance binding, Transfer Act diligence, personal property tax) are knowable in advance and frequently missed in conventional buy-side workflows.

Shop 1031 is an independent analytics platform. We are not a brokerage, a law firm, a tax advisor, a lender, or a Qualified Intermediary. Every 1031 exchange should be reviewed by a state-licensed real estate attorney, a CPA familiar with IRC §1031, and a QI. Brokerage and advisory services, when used, are provided by independently licensed third parties under separate engagement. This page is research, not advice. The Connecticut-specific surfaces discussed (no §1031 exemption from the state and municipal conveyance tax stack, high effective property tax with wide municipal dispersion, coastal hurricane and nor’easter exposure on Long Island Sound, Connecticut Transfer Act disclosure and remediation, municipal personal property tax) each carry material risk if mishandled and should be addressed with a Connecticut-licensed attorney, a Connecticut-licensed CPA, and a Qualified Intermediary before identification, not after.
