Definition
Employee onboarding is the process of integrating a new hire into an organization, from accepted offer through the first weeks or months of work. It covers paperwork, legal compliance, system access, role training, and introductions, with the goal of making the employee productive and connected quickly.
Also known as: onboarding, new hire onboarding
How it works
Onboarding usually starts after the offer is accepted, in a stage often called preboarding. The employer collects tax forms, direct deposit details, and policy acknowledgments, and completes employment eligibility verification on Form I-9. IT provisions equipment and accounts so the employee can work on day one.
After the start date, the focus shifts to orientation, role training, and relationships. Managers set early expectations, assign a buddy or mentor, and schedule check-ins at set points such as 30, 60, and 90 days. Onboarding software automates task lists, e-signatures, and reminders for HR, IT, and managers, and records completion for audit. Employers must also retain I-9 records for the required period, which a good onboarding workflow tracks automatically.
Example
A 150-person company sends new hires a digital packet a week before their start date. On day one, the employee has a laptop, completes Form I-9 with HR, and meets a buddy who guides them through a 90-day plan.

Frequently asked questions
How long should onboarding last?
Many employers treat onboarding as the first 90 days, with intensive activity in the first week. Complex roles may need longer. What matters is that expectations, training, and check-ins are scheduled in advance rather than left to chance, and that managers own the experience alongside HR.
How long must employers keep Form I-9?
USCIS states employers must retain and store Form I-9 for three years after the date of hire, or for one year after employment ends, whichever is later. Forms must be available for inspection by authorized government officials, so onboarding systems should track retention dates.
Do you get paid during onboarding?
Usually, yes. The US Department of Labor says training and similar sessions can be left unpaid only if they are outside normal hours, voluntary, not related to the job and no other work is done at the same time. Onboarding an employer requires rarely meets all four tests, so non-exempt new hires must be paid for that time.
What forms does a new hire fill out during onboarding?
In the US, every new employee completes Form I-9, which verifies identity and authorization to work, and Form W-4, which lets the employer withhold the correct federal income tax from pay. Employers then add their own policy acknowledgments and benefits enrollment.
What is the difference between onboarding and orientation?
Orientation is a single event, often on the first day, that introduces policies, tools and people. Onboarding is the longer process around it, from the accepted offer through the first months, and includes paperwork, training, check-ins and early goals.
What is preboarding?
Preboarding is the stretch of onboarding between the accepted offer and the first day: collecting forms, preparing equipment and accounts, and sending welcome information so the new hire can do real work on day one.
