Release:    2026-1.48.0          

Update: February 9, 2026

 

Canada

Alberta

Income Tax – Effective February 9, 2016

Corrected an issue: when an employee works in Alberta and has maxed out CPP contributions, the total income tax was correct; however, the distribution between federal and provincial taxes was off.

 

United States

Colorado

Paid Family Medical Leave (PFML) – effective January 1, 2025

We corrected an issue in the PFML auto adjust logic where employer pickup amounts could be overstated in certain scenarios.

When autoAdjust is true and year-to-date wages and withholdings were already aligned between pay periods, the engine could incorrectly recalculate and double the employer pickup amount, resulting in excess imputed income and over-withholding for taxes that treat the pickup as taxable.

The calculation has been updated so that, in these no-change auto adjust scenarios, the employer pickup amount remains consistent with prior periods rather than being recalculated from total year-to-date values.

 

Illinois

Income Tax – effective January 1, 2026

The tax  has been updated:

Oregon Transit – effective January 1, 2026

 The Oregon Department of Revenue has paused implementation of the increase while a voter referral petition is under review and has directed employers to continue withholding at the 0.1% rate. 

From the Oregon Department of Revenue:

In a special session in 2025, the Legislature adopted amendments to ORS 320.550 to increase the rate to two-tenths of 1 percent or .002 beginning January 1, 2026. After the special session, petitioners began collecting signatures for Initiative Petition 302, which would refer HB 3991 to Oregon voters. On December 12, 2025, petitioners submitted signatures to the Oregon Secretary of State to refer the bill to the voters. While signatures are being validated, the DOR is pausing implementation of the rate increase.

Please continue to withhold at the rate of one-tenth of 1 percent or .001. 

Paid Family Medical Leave (PFML) – effective January 1, 2025

We corrected an issue in the PFML auto adjust logic where employer pickup amounts could be overstated in certain scenarios.

When autoAdjust is true and year-to-date wages and withholdings were already aligned between pay periods, the engine could incorrectly recalculate and double the employer pickup amount, resulting in excess imputed income and over-withholding for taxes that treat the pickup as taxable.
