Update your contact information

Moved recently? It's important you always keep your address and state tax withholding up to date with Caterpillar. This ensures mailings are sent to the correct location and arrive in a timely manner, and that state tax withholdings are made for the correct states.

Caterpillar handles approximately 40 transactions per day resulting from incorrect employee address information, which leads to frustration and delays for employees and increased costs for the enterprise. Timeliness is important, especially for submitting an updated W-4 (state tax withholding form) - late notifications result in hundreds of manual corrections per year, as well as delays in providing corrected W-2s.

NOTE: Benefits information is sent to your mailing address on file. When you update your contact info, make sure the updates apply to both your home AND mailing addresses.
