New York State Personal Income Tax Components by Income and Residence, 1999 Onwards

The New York State Department of Taxation and Finance annually produces a statistical study file of timely filed personal income tax returns, beginning with tax year 1999. The data includes major tax structure components like income, deductions, dependent exemptions, and tax liability, broken down by income size and the filer's permanent place of residence (county, state, or country). Data is sourced from full-year resident, full-year nonresident, and part-year resident returns.

Use Cases

• Modeling tax liability distributions based on reported income and deductions.
• Analyzing regional economic disparities based on tax data aggregated by county or state of residence.
• Studying the impact of residency status (full-year, part-year, nonresident) on tax components.
• Tracking long-term trends in income and deductions for policy analysis from 1999 onwards.

Strengths

• Provides longitudinal data starting from tax year 1999, enabling trend analysis.
• Includes multiple tax structure components: income, deductions, exemptions, and liability.
• Data is disaggregated by size of income and by permanent place of residence (county, state, country).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to New York State tax filings.
