Overview
The Spring 2021 edition of IRS Publication 6292, Fiscal Year Return Projections for the United
States, provides U.S.-level projections of the number of tax returns expected to be filed in Fiscal
Year (FY) 2021 through FY 2028 by: (1) major return categories; and (2) business operating
divisions.
Statistics of Income (SOI) staff within the IRS Research, Applied Analytics, and Statistics (RAAS)
organization prepare these projections semiannually to incorporate changes in filing patterns,
economic and demographic trends, legislative requirements, and IRS administrative processes.

Data Sources and Projections Methodology
IRS Data Sources
To develop projections for FY 2021 through FY 2028, SOI staff relied on data from the IRS
Master File, which reports the historical number of returns processed and recorded each year.
In cases where master file return counts were not available, SOI staff relied on data provided by
program staff in the IRS operating divisions.
General Projections Methodology
SOI staff computed the projections presented here for the calendar year of filing, and then converted them to the corresponding fiscal year based on the historical quarterly filing experience.
For some individual return series, SOI staff computed the projections based on quarterly historical data and then derived the fiscal year projections by adding the relevant four quarters.
The projections are derived from various statistical models that capture and extrapolate historical filing trends by unique form types and filing mediums. Most of the models use time series
extrapolation methods, such as trended exponential smoothing. However, the projections for
some return types are based on regression models that used the April 2021 economic and demographic variables provided by IHS Markit as key input factors. Additionally, where historical
data were limited or nonexistent, such as for new e-file products, the filing pattern for a comparable return type was applied.
Adjustments Related to Implications from COVID-19 Pandemic
SOI staff performed an extensive research of U.S. laws and the IRS administrative processes
that will impact the FY 2021 to FY 2028 tax return volumes. The staff’s biggest challenges were
determining how to deal with the tax provisions of the Coronavirus Aid, Relief, and Economic Security (CARES) Act of 2020 and American Rescue Plan Act of 2021 (e.g., the effect of Recovery
Rebate Credits on filer behavior) and how to account for the backlog of paper returns that were
not processed in 2020 because of the IRS campus closures. Based on the SOI staff’s research
and the available 2021 filing season data as of early-May 2021, staff made appropriate adjustments to some of its modeled forecasts.
The impact of the COVID-19 pandemic led to the temporary closures of the IRS processing
centers in 2020. As a result, some of the paper returns that were received in 2020 could not be
processed and had to be carried over into 2021 for processing. This is evident in most of the
2020 actual paper volumes presented in this publication which are lower than expected based
on the historical trends. SOI staff adjusted the 2021 paper estimates to account for these carryover returns that were received in 2020 but processed in 2021.

New Electronic Filing Option for Form 1040-X
On May 28, 2020, the IRS announced that taxpayers could submit an Amended U.S. Individual
Income Tax Return (Form 1040-X) electronically using commercial tax-filing software. As e-filing
has grown in the past 30 years, the Form 1040-X was one of the last major individual tax forms
required to be filed on paper before August 2020.
To develop the initial projections for the new electronic Form 1040-X filing option, SOI staff
researched past scenarios and taxpayer filing behavior patterns following the IRS launch of a
new e-file option for other forms. The behavior observed and the number of returns submitted
electronically when past e-file options first became available is reflected in the projections of
electronic Form 1040-X returns. Actual Free File data from 2020 and year-to-date 2021 have a more
significant role in this year’s update of the electronic Form 1040-X forecasts.
The Impact of Taxpayer First Act
The Taxpayer First Act (TFA), enacted on July 1, 2019, made filing electronically a more widespread practice for business taxpayers. Two of the TFA provisions directly affect the forecasts
provided in this publication. First, the TFA lowers the thresholds needed for corporations and
partnerships to file electronically starting in CY 2021. Second, the TFA makes electronic filing
mandatory for exempt organizations (Form 990 series) and political organizations (Form 8872)
starting in CY 2021, with a temporary waiver for small business filers. Both provisions will increase the number of electronic filings for the various forms and will either decrease, or eliminate
altogether, the amount of paper filings.

Summary of Significant Trends
A summary of the major trends for this edition of Publication 6292 are noted below:
Trends in the Grand Total Return Filings
As presented in Table 1, the grand total return filings were 242.1 million in FY 2020, a decrease
of 5.2 percent over FY 2019. This is largely due to the backlog of individual tax returns filed by
paper and other types of taxpayer account work that IRS was unable to process in 2020 due to
the IRS campus closures. The paper grand total return filings were 46.4 million in FY 2020, a
decrease of 33.9 percent from the FY 2019 total.
The IRS is currently processing the paper backlog, along with processing the tax returns filed
in 2021, which will impact the FY 2021 count of overall paper returns (a projected 47.3-percent
increase in FY 2021 compared to FY 2020). However, the volume of overall paper returns is expected to return to its normal declining trend in FY 2022, with an expected count of 60.0 million.
After FY 2022, paper grand total returns are projected to decline by an average annual rate of
4.1 percent. Over the same time, grand total return filings are projected to grow at an average
annual rate of 1.1 percent, reaching 280.1 million by FY 2028.
In contrast to paper returns, the electronic grand total return filings were 195.7 million in FY
2020, an increase of 5.7 percent over FY 2019. The volume of electronic grand total returns in
FY 2021 is expected to be similar to the volume in FY 2020, with an expected count of approximately 195.7 million filings. After FY 2021, electronic grand total return filings are projected to
grow at an average annual rate of 2.5 percent.

Detail by Business Operating Division
Table 2 presents estimates of selected return filings by IRS Business Operating Division (BOD).
The selected returns include total individual income tax returns, corporation income tax returns,
partnership returns, employment returns, excise tax returns, and exempt organization returns.
As applicable, these volumes are broken out by their operating division components: Wage and
Investment (W&I), Small Business/Self-Employed (SB/SE), Large Business and International
(LB&I), and Tax Exempt/Government Entities (TE/GE). Also included are the projected total
filings of employee plan (EP) returns, including those processed by the Department of Labor,
which comprise major return filings by taxpayers served by the TE/GE operating division.

Accuracy of Prior Projections
To measure the quality of our products and services, this section, along with Table 3, provides
a brief analysis of the accuracy of prior projections. Using 4 years of actual data, from 2017
through 2020, Table 3 presents the accuracy of our national-level projections by major return
categories. This analysis covers only the major return categories projected on a calendar-year
basis and serves as a general measure for approximating the overall reliability of our U.S.-level
return projections.
The table presents two measures of projection accuracy: (1) the mean absolute percent error
(MAPE); and (2) the number of overprojections. The MAPE is computed as the average percentage projection error for the 4-year period, regardless of whether the projections were over or
under the actual filings in each of the four projection cycles. In addition, the number of overprojections can show whether projections are consistently over- or underprojected. A value of “2”
indicates balanced forecasts over the four cycles.
The table groups these two measures by time horizon. The time horizon is determined based on
the year a forecast was made and the year projected. For example, a forecast for 2019 made in
2016 would be part of the “3-years-ahead” time horizon.

Table Notes
• Detail may not add to total due to rounding.
• Projected return counts are rounded to the nearest hundred; therefore, counts of 49 or fewer
are rounded to 0. However, some forms may report zero filings because they are associated
with only selected areas, or because their filing options were recently established or eliminated.
• Actual and projected return counts for the major categories are based on IRS Master File
processing, as recorded in the electronic versions of the Report of Returns Posted to the IRS
Master Files.
Table 1:
• “Grand Total” is the sum of “Total Primary Returns” and “Supplemental Documents.” The “Total
Primary Returns” category is the sum of all forms shown in the table, excluding “Supplemental
Documents.”
• “Individual Income Tax, Total” is the sum of paper and electronic Forms 1040, 1040-SP, 1040SR, 1040-NR, 1040-NR-EZ, 1040-PR, 1040-SS, and 1040-C. Forms 1040-SP ( Declaración
de Impuestos de los Estados Unidos Sobre los Ingresos Personales) and Form 1040-SR
(U.S. Tax Return for Seniors) are new individual form types. More information about these new
forms can be found in Publication 6187, Calendar Year Projections of Individual Returns by
Major Processing Categories.
• “Individual Estimated Tax, Form 1040-ES” includes both paper and electronic Form 1040-ES.
Various return categories, such as Form 1040-ES and other business and individual returns,
include line items to account for alternative tax-filing methods. The “paper-only” components
can be derived by subtracting the electronic counts from their respective return totals.
• “Fiduciary, Form 1041, Total” includes both paper and electronic Form 1041.
• “Fiduciary Estimated Tax, Form 1041-ES” is the Estimated Income Tax for Estates and Trusts.
• “Partnership, Forms 1065/1065-B, Total” includes both paper and electronic Forms 1065 and
1065-B.
• “Corporation Income Tax, Total” includes Forms 1120 (paper and electronic), 1120-C, 1120-F
(paper and electronic), 1120-H, 1120-FSC, 1120-L, 1120-ND, 1120-PC, 1120-REIT, 1120-RIC,
1120-SF, and 1120-S (paper and electronic). Form 1120-POL volumes are reported separately
under the forms for “Political Organizations.” Form 1120-IC-DISC is not included in these corporation projections.
• “Form 2553” is the Election by a Small Business Corporation (to file Form 1120-S).
• “Form 1066” is the U.S. Real Estate Mortgage Investment Conduit (REMIC) Income Tax
Return.
• “Estate” includes Forms 706, 706-NA, 706-GS(D), and 706-GS(T).
• “Gift, Form 709” is the United States Gift (and Generation-Skipping Transfer) Tax Return.
• “Employment Tax, Total” includes paper and electronic Forms 940, 940-EZ, 940-PR, 941,
941-PR, 941-SS, 943, 943-PR, 943-SS, 944, 945, and CT-1. CT-2 is excluded since the return
counts were only available on the non-master file.
(8)

• “Form 1042” is the Annual Withholding Tax Return for U.S. Source Income of Foreign Persons. This form is assigned to the International area. It is sometimes considered an employment tax return but is listed separately here.
• “Exempt Organizations, Total” includes Forms 990 (paper and electronic), 990-EZ (paper and
electronic), 990-N (only available electronically), 990-PF (paper and electronic), 990-T (paper
and electronic), 4720 (paper and electronic), and 5227. Beginning in Calendar Year 2021, the
Form 990 series must be filed electronically. Temporary waivers are available for small business filers.
• “Form 1041-A” is the U.S. Information Return, Trust Accumulation of Charitable Amounts.
• “Government Entities/Bonds” includes Forms 8038, 8038-CP, 8038-G, 8038-GC, 8038-T,
8038-TC, and 8328.
• “Political Organizations, Total” includes Forms 1120-POL (paper and electronic), 8871 (only
available electronically), and 8872 (paper and electronic). Beginning in CY 2021, Form 8872
must be filed electronically. Temporary waivers will be available for small business filers.
• “Excise, Total” includes Forms 11-C, 720 (paper and electronic) 730, 2290 (paper and electronic), and 8849 (paper and electronic).
• “Form 5330” is the Return of Excise Taxes Related to Employee Benefit Plans.
• “Form 5500-EZ” is the Annual Return for One-Participant (Owners and Their Spouses) Retirement Plan.
• “Form 8752” is the Required Payment or Refund Under Section 7519.
• “Supplemental Documents” consists mainly of applications for extensions of time to file and filings of amended tax returns, which include Forms 1040-X (paper and electronic), 4868 (paper
and electronic), 1120-X, 5558, 7004 (paper and electronic), and 8868 (paper and electronic).
In August 2020, the IRS began allowing taxpayers to file Form 1040-X electronically.
Table 2:
• Individual filers classified as “Small Business/Self-Employed” reflect those taxpayers filing a
Form 1040 return with a Schedule C, Schedule F, Schedule E, and/or Form 2106 attached, or
with mailing addresses or forms considered “International.” All other individual filers are classified as “Wage and Investment.”
• In general, corporation filers (Form 1120 series returns including Form 1120-S) and partnership filers are classified as “Large Business and International” if their reported total assets are
$10 million or more. Corporation and partnership returns, with assets below $10 million, are
generally classified as “Small Business/Self-Employed.” However, there are also some partnership and corporation returns classified as part of the “Tax Exempt/Government Entities”
operating division.
• Nonprofit organizations, pension plan filers, tribal authorities, and governmental units comprise the “Tax Exempt/Government Entities” classification.
• “Employee Plans” returns include paper and electronic Forms 5500, 5500-EZ, and 5500-SF.
Counts by operating division in this table are based primarily upon the IRS Master File “BOD
indicator.” This indicator is a single, point-in-time, taxpayer-level identifier (in contrast to a
return-by-return identifier).
