PS 92(3.1)

Connecticut Income Tax on Bonds or Obligations Issued by the United States Government, by State Governments or Municipalities

This publication has been superseded by PS 2003(6)

BACKGROUND: Generally, the taxation of interest income for Connecticut income tax purposes conforms to its taxation for federal income tax purposes. In the case of certain bonds or obligations that are issued by the United States government, by State governments or by municipalities, there are exceptions. The interest of some may be taxable for federal income tax purposes or for Connecticut income tax purposes, but not for both.

PURPOSE: This Policy Statement indicates generally whether the interest income received on governmental obligations is subject to Connecticut income tax. This Policy Statement contains lists of such obligations, including a list of:

  • exempt obligations, the interest from which is to be subtracted from federal adjusted gross income in computing Connecticut adjusted gross income (see List A);
  • exempt obligations, the interest from which is not includable in federal gross income so that no subtraction is to be made from federal adjusted gross income in computing Connecticut adjusted gross income (see List B);
  • taxable obligations, the interest from which is includable in federal gross income so that no addition is to be made to federal adjusted gross income in computing Connecticut adjusted gross income (see List C); and
  • taxable obligations, the interest from which is to be added to federal adjusted gross income in computing Connecticut adjusted gross income (see List D).

These lists are neither all-inclusive nor intended to be conclusive of the taxable or exempt status of any particular obligation issued by or in conjunction with a listed agency or instrumentality. Even though a listed agency or instrumentality generally only issues either exempt obligations or taxable obligations, it does not follow that each and every obligation carrying the name of that particular agency or instrumentality is either exempt or taxable. An agency or instrumentality may issue its own obligations that are exempt and also may handle private obligations that are taxable. For example, the agency or instrumentality may administer, purchase and sell, insure, or guarantee an otherwise private obligation. Such action by the agency or instrumentality does not convert a private obligation into a direct and primary obligation of the United States government and, therefore, does not make the private obligation tax-exempt. The taxable status of each obligation must be determined separately in accordance with this Policy Statement.

STATUTORY AUTHORITY: Conn. Gen. Stat. §12-701(a)(10)(14) and (20). Conn. Agencies Regs. §§12-701(a)(10)-2, 12-701(a)(20)-2 and 12-701(a)(20)-3.

EFFECTIVE DATE: Applicable for income years beginning on or after January 1, 1992.

UNITED STATES GOVERNMENT OBLIGATIONS: 31 U.S.C. §3124(a) prohibits States from taxing income from stocks and obligations of the United States government. In Smith v. Davis, 323 U.S. 111 (1944), the United States Supreme Court described four characteristics of such obligations:

  1. written documents;
  2. the bearing of interest;
  3. a binding promise by the United States to pay specified sums at specified dates; and
  4. specific Congressional authorization which also pledged the faith and credit of the United States in support of the promise to pay.

Generally, the interest income received on United States government obligations is includable in federal adjusted gross income, which is the starting point for computing Connecticut adjusted gross income.

Individuals: Under Conn. Gen. Stat. §12-701(a)(20)(A)(i), any income with respect to which taxation by any state is prohibited by federal law (including interest income received from United States government obligations) is, to the extent properly includable in gross income for federal income tax purposes, to be subtracted from federal adjusted gross income in computing Connecticut adjusted gross income.

Trusts and estates: Under Conn. Gen. Stat. §12-701(a)(10)(B)(i), any income with respect to which taxation by any state is prohibited by federal law (including interest income received from United States government obligations) is, to the extent properly includable in gross income for federal income tax purposes, to be subtracted from federal taxable income in computing Connecticut taxable income.

  • Interest received on a federal income tax refund is not interest received on a United States government obligation because there is neither a written document in which the United States has promised to pay a definite amount at a specified date nor is there any binding acknowledgment by the United States of the correctness of the refund claim.
  • Interest received on obligations with respect to which the United States is merely the guarantor and not the obligor are not United States government obligations.
  • Interest must be paid by the United States government. Where a person ("the seller" ) other than the United States government sells to a buyer United States government obligations, and simultaneously agrees to repurchase these obligations at a future time for a price which includes interest from the date of sale ("repurchase agreement"), interest paid to the buyer at the time of repurchase is interest paid by the seller, not interest paid by the United States government on United States government obligations (and thus not to be subtracted from federal adjusted gross income of the buyer in computing Connecticut adjusted gross income). Any interest paid by the United States government on such obligations during the period prior to repurchase is paid to the seller, not to the buyer (and to be subtracted from federal adjusted gross income of the seller in computing the Connecticut adjusted gross income).

Modification for expenses - United States Government obligations:

Individuals: Under Conn. Gen. Stat. §12-701(a)(20)(A)(vii) and (viii), any interest on indebtedness paid, or incurred or continued to purchase or carry United States government obligations, the interest on which is exempt from Connecticut income tax, and the amortizable bond premium for the taxable year on any United States government obligations, the interest on which is exempt from Connecticut income tax, is, to the extent deductible in determining federal adjusted gross income, to be added to federal adjusted gross income in computing Connecticut adjusted gross income.

Trusts and estates: Under Conn. Gen. Stat. §12-701(a)(10)(A)(vi) and (vii), any interest on indebtedness paid or incurred or continued to purchase or carry United States government obligations, the interest on which is exempt from Connecticut income tax, and the amortizable bond premium for the taxable year on any United States government obligations, the interest on which is exempt from Connecticut income tax, is, to the extent deductible in determining federal taxable income prior to deductions relating to distributions to beneficiaries, to be added to federal taxable income in computing Connecticut taxable income.

OTHER INCOME THAT CONGRESS HAS PROHIBITED STATES FROM TAXING: Certain instrumentalities of the United States government are empowered to issue obligations to provide funding for their stated purposes. While these obligations may not meet the four characteristics of United States government obligations that were established in Smith v. Davis, the enabling legislation may prohibit the imposition of State or local taxes upon the obligations of these instrumentalities.

Individuals: Under Conn. Gen. Stat. §12-701(a)(20)(B)(i), any income with respect to which taxation by any state is prohibited by federal law (including income received from obligations which are not United States government obligations but which Congress has prohibited States from taxing) is, to the extent properly includable in gross income for federal income tax purposes, to be subtracted from federal adjusted gross income in computing Connecticut adjusted gross income.

Trusts and estates: Under Conn. Gen. Stat. §12-701(a)(10)(B)(i), any income with respect to which taxation by any state is prohibited by federal law (including income received from obligations which are not United States government obligations but which Congress has prohibited States from taxing) is, to the extent properly includable in gross income for federal income tax purposes, to be subtracted from federal taxable income in computing Connecticut taxable income.

  • A Congressional prohibition of State taxation of the income of a federal instrumentality is not to be extended beyond its express terms. For example, while Congress has prohibited States from taxing the income of federal credit unions, it has not prohibited States from taxing depositors on interest received on their deposits at such federal credit unions. Also, while Congress has prohibited States from taxing Federal Home Loan Bank bonds and debentures, it has not prohibited States from taxing depositors on interest received on demand/overnight deposits at such banks.

Modification for expenses - Obligations (other than United States government obligations) that Congress has prohibited States from taxing:

Individuals: Under Conn. Gen. Stat. §12-701(a)(20)(A)(vii) and (viii), any interest on indebtedness paid or incurred or continued to purchase or carry obligations or securities, the interest on which is exempt from Connecticut income tax, and the amortizable bond premium for the taxable year on any bonds or obligations, the interest on which is exempt from Connecticut income tax, is, to the extent deductible in determining federal adjusted gross income, to be added to federal adjusted gross income in computing Connecticut adjusted gross income.

Trusts and estates: Under Conn. Gen. Stat. §12-701(a)(10)(A)(vi) and (vii), any interest on indebtedness paid or incurred or continued to purchase or carry obligations or securities, the interest on which is exempt from Connecticut income tax, and the amortizable bond premium for the taxable year on any bonds or obligations, the interest on which is exempt from Connecticut income tax, is, to the extent deductible in determining federal taxable income prior to deductions relating to distributions to beneficiaries, to be added to federal taxable income in computing Connecticut taxable income.

STATE AND MUNICIPAL GOVERNMENT OBLIGATIONS: 26 U.S.C. §103(a) provides that, for federal income tax purposes, gross income does not include interest on any State or municipal government obligations. Such obligations do not include private activity bonds unless those bonds are "qualified bonds" within the meaning of 26 U.S.C. §141.

Individuals: Under Conn. Gen. Stat. §12-701(a)(20)(A)(i), any interest income from State and municipal government obligations (other than obligations of the State of Connecticut or of a Connecticut municipality) is, to the extent not properly includable in gross income for federal income tax purposes, to be added to federal adjusted gross income in computing Connecticut adjusted gross income.

Trusts and estates: Under Conn. Gen. Stat. §12-701(a)(10)(A)(i), any interest income from State and municipal government obligations (other than obligations of the State of Connecticut or of a Connecticut municipality or of any territory or possession of the United States, such as Puerto Rico, Guam and the Virgin Islands) is, to the extent properly not includable in gross income for federal income tax purposes, to be added to federal taxable income in computing Connecticut taxable income.

Modification for expenses - State and municipal obligations:

Individuals: Under Conn. Gen. Stat. §12-701(a)(20)(B)(viii) and (ix), any interest on indebtedness paid or incurred or continued to purchase or carry obligations or securities (including State or municipal government obligations (other than obligations of the State of Connecticut or of a Connecticut municipality or of any territory or possession of the United States, such as Puerto Rico, Guam and the Virgin Islands)), the interest on which is subject to Connecticut income tax but exempt from federal income tax, and the amortizable bond premium for the taxable year on any bonds (including State or municipal government obligations (other than obligations of the State of Connecticut or of a Connecticut municipality or of any territory or possession of the United States, such as Puerto Rico, Guam and the Virgin Islands)), the interest on which is subject to Connecticut income tax but exempt from federal income tax, is, to the extent that such interest on indebtedness is not deductible in determining federal adjusted gross income and is attributable to a trade or business carried on by such individual, to be subtracted from federal adjusted gross income in computing Connecticut adjusted gross income.

Trusts and estates: Under Conn. Gen. Stat. §12-701(a)(10)(B)(vi) and (vii), any interest on indebtedness paid or incurred or continued to purchase or carry obligations or securities (including State or municipal government obligations (other than obligations of the State of Connecticut or of a Connecticut municipality or of any territory or possession of the United States, such as Puerto Rico, Guam and the Virgin Islands)), the interest on which is subject to Connecticut income tax but exempt from federal income tax, and the amortizable bond premium for the taxable year on any bonds or obligations (including State or municipal government obligations (other than obligations of the State of Connecticut or of a Connecticut municipality or of any territory or possession of the United States, such as Puerto Rico, Guam and the Virgin Islands)), the interest on which is subject to Connecticut income tax but exempt from federal income tax, is, to the extent that such interest on indebtedness is not deductible in determining federal taxable income prior to deductions relating to distributions to beneficiaries, to be subtracted from federal taxable income in computing Connecticut taxable income.

MUTUAL FUNDS QUALIFIED TO PAY EXEMPT-INTEREST DIVIDENDS: If, at the close of each quarter of a mutual fund's taxable year, at least 50% of the value of the fund's assets consist of state and municipal government obligations described in 26 U.S.C. §103(a), that portion of the fund's distribution to its shareholders that is attributable to those obligations will qualify as exempt-interest dividends, as defined in 26 U.S.C. §852(b)(5). Exempt-interest dividends are properly not includable in federal gross income.

Individuals: Under Conn. Gen. Stat. §12-701(a)(20)(A)(ii), any exempt-interest dividends (other than those derived from obligations of the State of Connecticut or of a Connecticut municipality) are to be added to federal adjusted gross income in computing Connecticut adjusted gross income.

Trusts and estates: Under Conn. Gen. Stat. §12-701(a)(10)(A)(ii), any exempt-interest dividends (other than those derived from obligations of the State of Connecticut or of a Connecticut municipality or of any territory or possession of the United States, such as Puerto Rico, Guam and the Virgin Islands) are to be added to federal taxable income in computing Connecticut taxable income.
