What Is IRS Publication 1304?
IRS Publication 1304 is a detailed statistical report compiled by the IRS’s Statistics of Income Division. It presents aggregated data from a stratified probability sample of individual income tax returns, including Forms 1040 and 1040-SR, both paper and electronic filings. The report focuses on pre-audit data to ensure it represents the broader population of filers accurately.
The primary purpose of Publication 1304 is to provide transparent, reliable statistics on various aspects of individual taxation. It covers:
- Sources of Income: Including salaries, wages, dividends, capital gains, and more.
- Adjusted Gross Income (AGI): A key metric for determining tax liability.
- Deductions and Exemptions: Both standard and itemized, along with statutory adjustments.
- Tax Credits: Refundable and nonrefundable options that reduce tax burdens.
- Tax Computations and Payments: Details on income tax, self-employment tax, and overpayments/refunds.
The report is structured into several sections, including an introduction to changes in tax law, analyses of current-year data, discussions on tax rates and shares, basic tables categorized by income sources and deductions, explanations of terms, sample methodology, and an index for easy navigation. As of early 2026, the most recent edition (revised January 2025) covers Tax Year 2022, with data from returns filed primarily in 2023. Prior editions are available for comparison, dating back to 1990 in some tables.
This publication is essential for analyzing economic patterns, such as income inequality or the impact of tax policy changes. For instance, it highlights how legislative shifts—like the non-extension of enhanced credits from the American Rescue Plan Act—affect filing behaviors and tax outcomes.
Key Findings from the Tax Year 2022 Report
The 2022 edition of IRS Publication 1304 reveals intriguing trends in individual income tax returns, reflecting post-pandemic economic recovery and policy adjustments. Based on a sample representing approximately 161.3 million returns (up 0.3% from 2021), the report shows total AGI reaching $14.8 trillion, a modest 0.3% increase. Taxable income, however, dipped slightly to $11.7 trillion (down 0.5%), while income tax after credits totaled $2.1 trillion (down 5.1%).
Income Sources and Distributions
Income sources varied significantly by AGI brackets, with wages dominating lower income groups and capital gains playing a larger role in higher ones. Here’s a breakdown of major income categories:
| Income Source | Number of Returns (Millions) | Amount ($ Billions) | % Change from 2021 |
|---|---|---|---|
| Salaries and Wages | 128.4 | 9,739 | +7.9% |
| Taxable Interest | 49.7 | 134 | +29.0% |
| Ordinary Dividends | 32.9 | 412 | +6.6% |
| Net Capital Gains | 26.5 | 1,283 | -38.9% |

| Unemployment Compensation | 4.7 | 30 | -85.5% |
| Total Income | – | 14,978 | +0.3% |
Notably, the sharp decline in unemployment compensation reflects improved employment rates, while rising interest income may stem from higher rates in 2022. High-income filers (top 1% by AGI) accounted for 22.4% of total AGI but paid 40.4% of total income taxes, underscoring progressive tax structures.
Deductions and Adjustments
Deductions totaled $3.3 trillion (up 3.5%), with the standard deduction used by 88.5% of filers (142.8 million returns, amounting to $2.6 trillion). Itemized deductions, claimed by 9.5% of returns, reached $668 billion, including:
- Mortgage interest: $145 billion (up 4.7%)
- Taxes paid: $125 billion (up 4.7%)
- Charitable contributions: $222 billion (down 15.5%)
The qualified business income deduction was claimed on 25.7 million returns for $216 billion (up 5.0%), benefiting pass-through business owners.
Tax Credits and Payments
Tax credits played a crucial role in reducing liabilities, totaling $155 billion (up 3.1%). Refundable credits dropped significantly to $113 billion (down 51.7%), largely due to the reversion of child tax credit enhancements. Key credits include:
| Credit Type | Amount ($ Billions) | Number of Returns (Millions) | % Change from 2021 |
|---|---|---|---|
| Earned Income Credit (EIC) | 60 | 24.1 | -8.5% |
