Audited statements are also routinely expected by the Hartford Foundation for Public Giving, the Connecticut Health Foundation, the Fairfield County's Community Foundation, the United Way of Connecticut, and major Connecticut grantmakers.

Connecticut (CT) Tax & Business Landscape
Key Connecticut Tax Numbers. Personal income tax: graduated, top rate 6.99% on income above approximately $500,000 (single) / $1,000,000 (MFJ). Corporate income tax: 7.5% base rate plus a 10% surtax on companies with $100M+ in capital base or with income above $250K — effective combined top approximately 8.25%. Sales and use tax: 6.35% statewide (no local add-on). Estate tax: applies above the federal exemption (currently approximately $13.61 million in 2024, indexed) at rates up to 12%. Gift tax: yes — Connecticut is currently the ONLY U.S. state with its own gift tax, unified with the estate tax exemption. Pass-Through Entity Tax (PE Tax): 6.99% top rate, the first PTE in the country (effective tax year 2018), originally mandatory and now elective starting tax year 2024. For hedge fund and PE partners, insurance executives, defense and aerospace professionals, and high-net-worth families navigating CT's combined estate and gift tax, these numbers matter most when entity structure, owner compensation, residency, property, or investment decisions change the federal and state result.
Filing Mechanics. Individuals file Form CT-1040 (residents) or CT-1040NR/PY (nonresidents and part-year residents). C-corporations file Form CT-1120. Pass-through entities file Form CT-PET for the PE Tax election. CT estate tax is filed on Form CT-706/709 (combined estate and gift return). Returns are due April 15 and administered by the Connecticut Department of Revenue Services (DRS). We use those mechanics to build a filing calendar and document request list for hedge fund and PE partners, insurance executives, defense and aerospace professionals, and high-net-worth families navigating CT's combined estate and gift tax before deadlines compress the planning options.
NY Commuter & Multi-State Considerations. Connecticut has no reciprocity with any neighboring state. CT residents owe CT tax on worldwide income but receive a credit for NY State (and NYC if applicable), MA, RI, or NJ tax paid on income sourced there. The credit is generally limited to what CT would have charged on the same income. CT residents working remotely from CT for NY employers face the NY "convenience of the employer" rule, which often makes those wages NY-source despite remote work — a major issue for the Fairfield County financial services population.
Connecticut Economy & Who We Serve. Connecticut is anchored by the insurance industry centered in Hartford ("the insurance capital of the world" — The Hartford, Aetna/CVS, Travelers, Cigna), defense and aerospace manufacturing (RTX/Pratt & Whitney, Sikorsky, Electric Boat submarines in Groton), pharmaceuticals (Pfizer's R&D in Groton), and the world's largest concentration of hedge funds and private equity in Fairfield County (Greenwich, Stamford, Westport — Bridgewater, AQR, Tudor, Point72, etc.). Our typical CT clients include hedge fund and PE partners, insurance executives, defense and aerospace professionals, and high-net-worth families navigating CT's combined estate and gift tax.

Connecticut CPA — Frequently Asked Questions
Do I need a Connecticut-licensed CPA, or can an out-of-state CPA handle my CT tax and audit work?
CPA mobility often allows an out-of-state CPA in active good standing to serve Connecticut clients, but the right answer depends on the engagement type. For hedge fund and PE partners, insurance executives, defense and aerospace professionals, and high-net-worth families navigating CT's combined estate and gift tax, we confirm whether the work is tax, advisory, attest, employee-benefit-plan, or state-sensitive before accepting the engagement.
What is Connecticut's income tax rate, and when is the CT return due?
Connecticut has a graduated personal income tax with a top rate of 6.99% on income above approximately $500,000 (single) / $1,000,000 (MFJ). Form CT-1040 (residents) or CT-1040NR/PY (nonresidents and part-year residents) is due April 15.
Is Connecticut really the only state with a state-level gift tax?
Yes. Connecticut is currently the only U.S. state that imposes its own gift tax — separate from (but parallel to) the federal gift tax. The CT gift tax exemption is unified with the CT estate tax exemption (currently tied to the federal exemption of approximately $13.61 million in 2024). Lifetime gifts above the CT exemption are subject to CT gift tax at rates up to 12%, even if no federal gift tax applies. This makes lifetime gifting strategy materially different for CT residents than for residents of other states.
Does Connecticut have a SALT-cap workaround for partnerships and S-corps?
Yes. Connecticut enacted a Pass-Through Entity Tax (PE Tax) effective for tax years beginning on or after January 1, 2018 — the first state PTE in the country. Originally mandatory, the CT PE Tax became elective starting with tax year 2024. The top rate is 6.99% (matching the personal IT top rate), and members receive a corresponding credit on Form CT-1040. The election (or, prior to 2024, the mandatory filing) is made on Form CT-PET.
I live in Connecticut and work in New York City. How is my tax return affected?
CT residents owe CT tax on worldwide income but receive a credit for NY State (and NYC if applicable) tax paid on NY-sourced wages. CT does NOT have reciprocity with NY (or any other state). CT residents working remotely from CT for NY employers face the NY "convenience of the employer" rule, which often makes those wages NY-source despite remote work. We routinely handle CT/NY commuter mechanics.
When does my Connecticut nonprofit need an audit?
Under Connecticut's Solicitation of Charitable Funds Act, charities registered with the Department of Consumer Protection are generally required to submit audited financial statements when annual gross revenue exceeds $500,000, and reviewed financial statements when gross revenue is between $200,000 and $500,000. Federal Single Audit requirements under 2 CFR Part 200 apply separately when federal award expenditures exceed $1,000,000 in a fiscal year.
Do you serve Connecticut clients outside Hartford and Stamford?
Yes. Our practice is virtual-first, so we serve clients across all of Connecticut — including Greenwich, New Haven, Bridgeport, Norwalk, Danbury, Waterbury, West Hartford, New Britain, Bristol, Meriden, Fairfield County, the shoreline, and every Connecticut community — with the same level of access and service.
