Free, no-signup tools · Tax years 2020–2026
According to the Internal Revenue Service Revenue Procedures covering tax years 2026, 2025, 2024, 2023, 2022, 2021, 2020, every tool on this hub reads the same official bracket, deduction, and credit tables. Calculators run entirely in your browser; nothing is sent to a server.
The two ranks diverge
According to IRS Revenue Procedure 2025-32, tax year 2026 is #1 of 7 published years by Single standard deduction ($16,100) but only #5 of 6 year-over-year pairs by Single 37% threshold inflation lift (2.3%). 2023 is #1 on the inflation-lift map at 7.1%.
Highest published Single deduction is not the same ordering as the largest Single 37% threshold inflation lift. See methodology for how tax years are placed in the IRS Revenue Procedure corpus.
