The IRS reduction announced for 2026 will require companies and other paying entities to update their withholding tables. This update will need to be done at two distinct times: in November and in January.
The changes will reflect the new IRS rates to be applied, as well as automatic updates to income brackets. The specific deduction will also be updated as part of these changes.
Taxpayers will feel the impact of these changes in their salaries even before the 2026 tax settlement, which corresponds to the IRS declaration for that year.
