Connecticut Estate Tax Planning: Using Bypass and SLAT Trusts for High-Net-Worth Families

Navigating the Connecticut Estate Tax Threshold

Connecticut is unique because it is one of the few states that imposes its own state-level estate tax, governed by C.G.S. § 12-391. The state sets a statutory exemption threshold of $15.0 million per individual (or $30.0 million for married couples using both exemptions), which families residing in affluent areas like Greenwich, Darien, or Westport can quickly approach when combining real estate, business valuations, and stock portfolios. Rather than a tax 'cliff,' Connecticut applies a flat 12% tax rate strictly to the excess value over the $15.0 million threshold under C.G.S. § 12-391(g), on top of federal estate taxes. Fortunately, high-net-worth individuals can use advanced estate planning tools like Bypass Trusts (AB Trusts) and Spousal Lifetime Access Trusts (SLATs) to shield their wealth and pass their legacy to the next generation intact.

Step-by-Step Process in Connecticut

Advanced tax planning is highly technical. Most applicants in this state choose to collaborate with specialized estate attorneys and Certified Public Accountants to structure these complex entities correctly.

Step 1: Comprehensive Estate Valuation

The first step is determining your global net worth. This includes appraising your primary residence in Fairfield County, any secondary vacation homes, liquid investments, retirement accounts, and business interests. Accurate valuation is critical to determine if you actually face an estate tax liability.

Step 2: Choosing the Right Trust Structure

Your attorney will help you decide between an AB Trust (Bypass Trust) or an Irrevocable SLAT. A Bypass Trust activates after the first spouse dies, shielding their exemption amount from taxes when the second spouse eventually passes. A SLAT, however, is funded while both spouses are still alive, locking in the current exemption limits before potential future legislative cuts.

Step 3: Drafting the Legal Instruments

Drafting these trusts requires precision. Your attorney will prepare the trust documents, ensuring they strictly comply with IRS regulations and Connecticut Department of Revenue Services, Hartford guidelines to prevent the trust from being invalidated during an audit.

Step 4: Irrevocable Asset Transfers and Tax Filings

For tools like a SLAT, you must legally transfer ownership of assets out of your name and into the trust. This involves recording new deeds with the Town Clerk, executing stock transfer forms, and filing both a federal Form 709, Federal, IRS, United States Gift (and Generation-Skipping Transfer) Tax Return and a state Form CT-706/709, Connecticut, Department of Revenue Services, Connecticut Estate and Gift Tax Return under C.G.S. § 12-642. Because Connecticut is the only state with a standalone gift tax, properly reporting gifts to the Department of Revenue Services is mandatory to track your lifetime exemption balance.

Fairfield County Real Estate Investors

For families in Fairfield County, real estate appreciation is a major driver of estate tax liability. A waterfront property in Stamford or Westport bought decades ago may now be worth millions, pushing an estate over the threshold. By transferring ownership of investment properties or secondary homes into a SLAT, the future appreciation of that real estate occurs entirely outside your taxable estate under C.G.S. § 12-391. This strategy locks in the value of the property at the time of the gift, saving your heirs from a massive tax bill tied to future market booms.

Protecting Connecticut Business Owners

If you own a successful manufacturing firm or tech startup in Hartford or New Haven, your business valuation could easily trigger estate taxes. Business owners frequently utilize Bypass Trusts within their estate plans. When the first spouse passes away, their shares of the business are funneled into the Bypass Trust up to the exemption limit. The surviving spouse can still receive income generated by the business, but when they pass, those shares bypass the surviving spouse's taxable estate, ensuring the business transitions smoothly to your children without being liquidated to pay the IRS.

Executives with High Stock Options

Corporate executives often have immense wealth tied up in company stock and restricted stock units (RSUs). Utilizing a SLAT allows an executive to gift shares (once vested) into an irrevocable trust for the benefit of their spouse. The beauty of the SLAT is that while the assets are removed from the executive's taxable estate, the spouse can still access trust distributions if the family needs liquidity. It is the ultimate 'have your cake and eat it too' strategy for highly compensated professionals looking to reduce their C.G.S. § 12-391 exposure.

How Much Does it Cost in Connecticut?

Advanced estate planning requires custom drafting and tax strategy, which is significantly more expensive than a basic living trust. However, the upfront cost is minuscule compared to saving millions in taxes.

How Long Does the Process Take?

Because of the financial modeling and appraisals required, designing and funding advanced tax trusts typically takes 2 to 4 months. Business valuations alone can take 6 weeks. It is crucial to start this process well before the end of the calendar year to ensure all gift tax returns and asset transfers are properly recorded.
