The Internal Revenue Service received and processed less returns during 2026, according to the Treasury Inspector General for Tax Administration.
In a recently released report, TIGTA stated that from March 1, 2025, through February 28, 2026, the IRS received 51.5 million tax returns, down from 52. 4 million in the previous year, though it did see a significant drop in paper returns received from 1.2 million in 2025 to 618,000 in 2026. Of the returns received in 2026, the agency processed 50.9 million returns, down from 51.8 million.
From the beginning of the 2026 tax filing season to the end of February 2026, TIGTA reported that the inventory backlog in key tax return processing programs increased from 1.9 million to 2.4 million. Additionally, nearly 75 percent of the amended return inventory is over-aged during the 2026 tax filing season.
“Generally, inventories increase during the filing season as the IRS balances efforts to answer phone calls and reduce inventories,” TIGTA stated in the report. “However, with the reduction in staff, increases in key inventories could become a concern.”
The number of refunds dipped to 36.5 million from 36.9 million, although there was a $360 increase in the average refund from $3,382 in 2025 to $3,742.
TIGTA also reported that the IRS did not meet its hiring goals for the 2026 tax filing season. The agency had been approved to hire 1,900 employees for submission processing (these workers process original and amended returns and resolve tax return errors) but only onboarded 800 individuals. Likewise, it was approved to hire 3,500 account management employees (handlers of taxpayer contacts through telephone and mail and process adjustments) but brought 2,300 on board.
Submission processing management said it would be onboarding new hires throughout the tax season, while account management leadership had no plans to hire new employees and would only be onboarding those who previously received offers but had delays in the hiring process.
In a positive from the 2026 season, TIGTA reported that the new and modified “e-file business rules associated with the child tax Credit, state and local tax deduction, and adoption credit are working as intended.”
