Introduction – What is Publication 6187?
IRS Publication 6187, formally titled “Calendar Year Projections of Individual Returns by Major Processing Categories,” is an annual research and forecasting report published by the Internal Revenue Service. Instead of providing instructions on how to fill out a tax return, this publication forecasts how many individual tax returns taxpayers will submit across the United States over multi-year periods. It details return volumes by filing method, form category, processing campus, and refund type.
The current operational baseline governing 2026 tax administration carries a revision date of December 2025 and was officially posted by the IRS on December 17, 2025. This edition relies on economic and tax administration data compiled through July 2025 to project filing volumes through 2028. The data shows that after processing 159.3 million individual returns in calendar year 2024 and 161.5 million in 2025, return volumes continue expanding across 2026 on track toward an estimated 164.1 million returns by 2028.
A central highlight of the latest data for 2026 is the overwhelming dominance of electronic filing, which represents over 95% of all individual returns filed. Paper returns continue their steady decline down to roughly 6% of total individual filings. The report also accounts for major modernization efforts, including the IRS Zero Paper Initiative and digital intake scanning procedures designed to streamline processing operations nationwide.
Who Should Read This Publication
While general taxpayers do not need Publication 6187 to file their annual tax returns, the report offers valuable insights for several key audiences:
- Tax Professionals and CPA Firms: Accountants and tax preparers use these volume trends to anticipate seasonal workloads, evaluate industry-wide shifts toward digital filing, and plan business staffing.
- Software Developers: Commercial tax software vendors rely on IRS volume projections to test server infrastructure, manage transmission capacity, and support expected e-file demand.
- Policy Makers and Budget Analysts: Government economists and legislative advisors use the data to monitor taxpayer compliance methods, track refund demands, and evaluate administrative budgets.
- Students and Tax Researchers: Academics studying fiscal administration find rich historical and predictive datasets reflecting real-world taxpayer behavior.
Key Topics Covered
Publication 6187 serves as a statistical map of individual federal tax administration. Its primary sections examine the following topics:
- Overall Individual Return Volumes: Multi-year estimates of total individual returns filed across the United States.
- Filing Mediums: Detailed breakdowns comparing paper submissions against electronic filings.
- Filer Type: Projections distinguishing self-prepared online returns from returns submitted through professional tax practitioners.
- Payment Status: Forecasts dividing returns into fully paid returns, returns with balance due, and refund returns.
- Campus Workloads: Operational return distributions across various IRS submission processing campuses.
Detailed Breakdown of Main Concepts
Electronic vs. Paper Return Trajectory
One of the most important metrics in Publication 6187 is the split between electronic filing and traditional paper mail. E-filing has risen steadily from under 90% a decade ago to nearly 96% in recent projections. Paper returns are becoming a niche filing method, prompting the IRS to restructure its physical intake facilities.
Do-It-Yourself Online vs. Tax Practitioner Filing
The publication analyzes whether taxpayers prepare returns on their own or hire paid professionals. While paid preparers still account for the majority of e-filed forms (over 84 million returns), direct online self-filing by individuals continues to expand rapidly. This shift directly influences IRS public assistance programs and taxpayer self-service portals.
Full-Paid Returns, Balances Due, and Refunds
The IRS categorizes returns based on their financial settlement status. Publication 6187 models how many filers will receive a refund, how many will pay their full tax obligation when filing, and how many will require payment arrangements or installment agreements. This data helps the Treasury anticipate refund disbursements and incoming revenue flows.
The Zero Paper and Digital Intake Modernization
Recent editions of Publication 6187 reflect IRS modernization initiatives funded by long-term technological transformation plans. Initiatives like the Zero Paper Initiative and automated scanning allow paper forms to be converted into digital data immediately upon intake. While historical publications treated paper processing separately, current forecasts reflect an agency transitioning toward fully digitized intake workflows.
Practical Examples or Scenarios
Scenario 1: A Tax Prep Software Provider Planning Infrastructure
A cloud tax preparation platform uses Publication 6187 to anticipate filing spikes during peak tax weeks in February and April. Seeing that direct online consumer filing accounts for over 64 million returns nationally, the engineering team scales cloud server capacity to ensure zero downtime during peak electronic submission hours.
Scenario 2: A Regional Accounting Practice Expanding Services
A regional tax practice reviews the growth rate of practitioner e-filings versus self-prepared returns. The partners note steady demand for professional filing support and use the regional campus data to schedule staffing across multiple offices for the upcoming filing season.
Scenario 3: An Academic Studying IRS Processing Turnaround
A university researcher compares past Publication 6187 paper filing projections with actual paper return backlogs. By cross-referencing the decline in paper volumes with the rollout of the Zero Paper scanning program, the researcher evaluates whether digital intake improves IRS response times.
How This Publication Relates to Specific Forms
Publication 6187 groups individual tax returns into specific form categories to forecast processing workloads accurately:
| Form Number | Form Name / Type | Role in Publication 6187 Projections |
|---|---|---|
| Form 1040 | U.S. Individual Income Tax Return | Represents the core volume of all individual filing projections, tracked across e-file and paper formats. |
| Form 1040-SR | U.S. Tax Return for Seniors | Specifically monitored to track filing preferences and paper usage among taxpayers age 65 and older. |
| Form 1040-NR | Nonresident Alien Income Tax Return | Tracked separately due to unique processing workflows and international tax compliance requirements. |
| Forms 1040-PR / 1040-SS | Territory & Self-Employment Forms | Forecasts filings from Puerto Rico and other U.S. territories to allocate specialized campus resources. |
| Form 8888 | Allocation of Refund | Used to project split-refund activity, where filers distribute tax refunds across multiple bank accounts. |
Common Misunderstandings Clarified
Because of its numeric designation, taxpayers frequently confuse Publication 6187 with instructional tax guides. Here are common misconceptions clarified:
- Misunderstanding 1: It is a guide for filing your annual taxes. Publication 6187 is strictly a forecasting and statistical research document. It does not contain tax brackets, deduction worksheets, or instructions for preparing your tax return.
- Misunderstanding 2: The projections represent official revenue collections. This publication projects the volume of return documents submitted, not the dollar amount of total taxes collected by the U.S. government.
- Misunderstanding 3: Paper returns are no longer accepted. Although the publication highlights dramatic drops in paper filing, the IRS continues to accept paper returns while modernizing paper intake through automated scanning.
- Misunderstanding 4: Projections include unpassed tax bills. IRS forecasting models rely exclusively on enacted statutory tax laws and confirmed administrative rules, excluding speculative or pending legislation.
Why This Publication Matters for Taxpayers
Even though ordinary filers do not complete Publication 6187, its projections directly affect your experience as a taxpayer. The IRS uses these projections to set customer service staffing levels, operate toll-free phone lines, and assign agents to process refunds.
When the IRS accurately projects an increase in digital returns, it can allocate more resources toward online account services and direct deposit tools. Conversely, underestimating filing surges can result in customer support delays and slower refund processing. In short, Publication 6187 helps ensure the agency is equipped to handle millions of tax returns without operational bottlenecks.
