State Income Tax Policies in 2023
Conformity with Federal Tax Changes 1 Presence of State Credits
State Must itemize if itemized on federal return? Repeal of Deduction of Theft Losses and Casualty Losses (other than for national disasters) Repeal of Deduction of Misc Expenses State and Local Tax (SALT) Deduction Cap ($10,000) Charity Limit in 2020 ($300 for non-itemizers; limit at 100% of AGI) Charity Limit in 2021 ($600 for non-itemizers; limit at 100% of AGI) Charity Limit in 2022 and 2023 (return to 60% of AGI for itemizers) UI Exclusion from Income Child Tax Credit (CTC) Child and Dependent Care Credit Earned Income Tax Credit (EITC) Aspects of State Income Tax Not Currently Captured
Federal Charitable contribution limitation remains at 100% of AGI, plus $300 limit for non-itemizers. Charitable contribution limitation remains at 100% of AGI, plus $600 limit for non-itemizers. Charitable contribution returns to 60% of AGI for itemizers. Removed for 2021 Standard deduction of $300/$600 in charitable contribution not implemented. Charity is imputed from IRS SOI, and it only exists for itemizing households in SOI. Individual Mandate not tracked; cannot accurate capture health insurance status/exemption. OASDI tax deferral not tracked, since it's paid in following year Non-taxable loans from retirement plans For states that use same filing status as federal returns, we currently determine deduction type using federal status; should implement code to take standard or itemized deductions by sum of federal and state deductions.

Arkansas No No No No N Full UI exclusion under state law n/a No n/a credit for dependents with developmental disabilities
California No No No No N Full UI exclusion under state law No No No We do not track individual mandate penalty due to poor matching of gaps in health insurance.
Colorado n/a n/a n/a n/a Y No exclusion n/a Yes Yes

Delaware No Yes Yes Yes Y Full UI exclusion under state law n/a Yes Yes
DC Yes Yes Yes Yes Y Full UI exclusion under state law n/a Yes Yes Homeowner and Renter property tax credit could be added if we have rent data. Does not model ELC, since "child development facility" expenses cannot be captured. Does not capture non-custodial parent EITC. We do not track individual mandate penalty due to poor matching of gaps in health insurance.
Florida n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) ***NO STATE INCOME TAX***

Illinois n/a n/a n/a n/a N/A Conforms to federal n/a n/a Yes
Indiana n/a n/a n/a n/a N/A Partial UI exclusion under state law n/a n/a No Currently not tracking AGI limits for Indiana EIC as they are slightly different from federal AGI limit (also different for Indiana self-employed and clergy workers). County tax rates are weighted average for the whole state.
Iowa No No No No Y Conforms to federal n/a Yes Yes In Iowa, it is more adventageous for married couples to file separately. I think this accounts for most of the difference between our tax model and the Bakija tax model / aggregate tax targets. Do we want to consider coding married filing separately for certain states?
Kansas Yes (but allowed to take standard deduction if larger) n/a n/a n/a Y Conforms to federal n/a Yes Yes
Kentucky No n/a Yes n/a N No exclusion n/a No n/a
Louisiana n/a n/a n/a n/a Y Conforms to federal n/a Yes Yes If the number of parameters in the latcut1 and latcut2 arrays changes, double check the SAS code. There is some hard coding that may need to change if the number of items in the arrays change.

Maryland Yes (but allowed to take standard deduction if larger) n/a n/a Yes Y Full UI exclusion for some filers, otherwise uses federal AGI. n/a Yes Yes We don't model the state's military pay exclusion (which they enacted in tax year 2017) because it only applies to military pay received while serving overseas. Maryland EIP is not captured as it uses 2019 tax return (available to those who qualify for EITC in 2019)
Massachusetts n/a n/a n/a n/a N/A Limited UI exclusion for some filers. n/a Yes Yes We do not track individual mandate penalty due to poor matching of gaps in health insurance.
Michigan n/a n/a n/a n/a N/A Conforms to federal n/a n/a Yes In 2018, Michigan added retirement benefits for some retirees who are not covered by Social Security, but we are not modeling this at this time. Cannot capture qualified benefits from deceased spouse.

Missouri Yes (but allowed to take standard deduction if larger) n/a n/a Yes Y Conforms to federal n/a n/a n/a Cannot capture earnings portion of state and local income taxes for component in itemized deduction. Cannot capture business income deduction from Missouri-source.
Montana No Yes Yes Yes Y Full UI exclusion n/a No Yes
Nebraska Yes (but allowed to take standard deduction if larger) Yes Yes No Y Conforms to federal n/a Yes Yes Doesn't model military retirement benefits exclusion as the model might overestimate the number of people eligible since one could retire with full pension as early as 37 and one must file for the exclusion within 2 year of retirement.
Nevada n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) n/a (no state tax) ***NO STATE INCOME TAX***

New Jersey n/a n/a n/a n/a N/A Full UI exclusion n/a Yes Yes We don't model the state's property tax deduction, because while we could model the deduction for homeowners the state also allows renters to deduct a certain percentage of their rent (which we cannot model). We decided not to model at all to prevent inaccurate distributional effects. State also has an additional exemption for veterans, but we don't have information on the CPS about veteran status. We do not track individual mandate penalty due to poor matching of gaps in health insurance.
New Mexico Yes n/a n/a No N/A Conforms to federal n/a No Yes
New York No No No No Y No exclusion No No No Higher tax rates and brackets as AGI never exceed 5 million due to top-coding. New York city child credit not modeled cannot disentangle share of expenses spent on children under 4 in NYC, will not include in model

Introduction

Brief Documentation for Federal and State Tax Parameter Workbook: 2023
The Census Bureau imputes federal, state, and payroll tax liabilities and tax credits via a microsimulation tax model using the Current Population Survey Annual Social and Economic Supplement (CPS ASEC), the Internal Revenue Service (IRS) Statistics of Income Public Use File (SOI PUF), and information from federal and state tax forms and instructions. The microsimulation model contains two primary components: a collection of SAS programs and a workbook of federal and state tax parameters.
This federal and state parameter workbook holds the key parameters that are used in the calculation of federal and state income taxes for the 2023 CPS ASEC tax model. In addition, the workbook describes where the parameters can be found in tax forms and/or instructions, making it easier to reference additional information on the parameter and to update the parameter each year.
In this workbook, there is a spreadsheet with all the parameters needed to calculate federal payroll and income tax, plus spreadsheets with the parameters for each state with an income tax. Each of the spreadsheets follows the same structure. The first column in each spreadsheet (“Parameter”) includes the variable name used for the parameter in the tax model SAS programs. The second column (“Description”) provides a brief description of what is captured by the parameter. The third column (“2023 Value”) contains the numerical parameter or array for tax year 2023. The fourth column (“2023 Source”) describes where the value can be found in federal or state tax forms and/or instructions.
There are limitations to the information captured in the parameter workbook. Refer to the full documentation of the federal and state parameter workbook for a description of the limitations (https://www2.census.gov/library/working-papers/2024/demo/Federal_and_State_Tax_Parameter_Workbook_Documentation_TY2023.pdf).
