HP Retirement Services typically allows participants to roll over funds from other qualified retirement accounts, such as a 401(k) plan or an Individual Retirement Account (IRA), into their retirement plans. However, it is important to review specific plan documents and requirements, as the processes and eligibility can vary. Generally, to initiate a rollover, participants must complete necessary paperwork and ensure that the funds from the other account are eligible. The timeline for completing the rollover can also differ depending on the type of account and any previous arrangements with the original custodian. For accurate and detailed information, it is advisable to visit the official HP Retirement Services website. There, you can find resources and contact information that can assist you further in this process.
