Kronos payroll is a workforce management and payroll processing system now operated under the brand name UKG (Ultimate Kronos Group). If your employer uses “Kronos” for timekeeping or paychecks, they’re running one of UKG’s software platforms, which handle everything from clocking in and out to calculating taxes and issuing direct deposits. The Kronos name stuck around in everyday workplace conversation even after the company merged with Ultimate Software in 2020 to form UKG Inc.
How Kronos Became UKG
Kronos Incorporated spent decades as one of the largest workforce management companies in the U.S., best known for its time clocks and scheduling software. In 2020, Kronos merged with Ultimate Software, a payroll and HR technology company, creating UKG Inc. The combined company kept the core Kronos products but rebranded them. So when coworkers or managers mention “Kronos,” they’re usually referring to a UKG product that still carries the legacy name internally or in conversation.
The Main UKG Payroll Products
UKG sells its payroll and HR tools primarily through two software suites, each aimed at a different size of organization.
UKG Pro is the full human capital management (HCM) platform built for mid-size to large employers. It covers payroll processing, benefits administration, talent management, and compliance reporting in a single system. Organizations with complex pay structures, multiple locations, or thousands of employees typically use Pro.
UKG Ready is an all-in-one HR and payroll solution designed for growing businesses. It bundles time tracking, scheduling, payroll, and basic HR functions into one platform, making it a popular choice for companies that want a single tool rather than juggling separate vendors for each function.
For companies operating across borders, UKG One View handles multi-country payroll management, consolidating pay runs and compliance requirements for international workforces into one dashboard.
What Kronos Does for Employees
If you’re an employee whose company uses UKG (Kronos), the system touches several parts of your work life. The employee self-service portal lets you clock in and out for shifts, request time off, and view your work schedule. On the payroll side, you can pull up current and past pay statements, manage your direct deposit settings, and update personal information like your address or emergency contacts. You can also reset your own password and update security questions without calling HR.
Tax documents like W-2s are typically available through the same portal. Around tax season, your employer will generate those forms within the system, and you can download or print them directly. If you’ve ever been told to “check Kronos” for your pay stub, this self-service portal is what they mean.
What Kronos Does for Employers
On the administrative side, UKG’s payroll engine automates the heavy lifting that used to require manual spreadsheets or separate tax software. The system supports more than 8,000 U.S. tax codes along with Canadian payroll requirements, automatically calculating federal, state, and local withholdings each pay period. When tax rates or wage laws change, the platform pushes automatic updates so payroll administrators don’t have to track legislative changes themselves.
Wage garnishments, which are court-ordered deductions from an employee’s paycheck for things like child support or debt repayment, are also handled automatically. The system calculates the correct amount, applies it to the right paycheck, and tracks the balance over time.
For Affordable Care Act (ACA) reporting, the platform auto-populates 1094-C and 1095-C forms and lets employers submit filings directly, cutting down on the manual data entry that makes year-end reporting error-prone. The system also handles global data privacy compliance for organizations subject to regulations like GDPR in Europe or CCPA in the U.S., using role-based permissions to control who can see sensitive employee data.
UKG has embedded AI tools that scan payroll and compliance data continuously, flagging potential risks like misclassified employees or missed filing deadlines. Administrators receive alerts with suggested next steps rather than having to audit manually.
Time Tracking and Scheduling
Kronos originally made its name with physical time clocks, and time tracking remains central to the platform. The UKG InTouch DX is the company’s current timeclock hardware, used in workplaces where employees punch in at a physical terminal. For desk workers or remote employees, the software offers browser-based and mobile clock-in options that feed directly into the payroll system.
Scheduling tools vary by industry. UKG Shiftboard handles complex shift scheduling for industries like manufacturing, energy, and healthcare where 24/7 operations and safety compliance matter. UKG TeleStaff Cloud is purpose-built for public safety agencies like police and fire departments. These specialized tools sit alongside the core payroll system, so hours worked flow automatically into pay calculations without double entry.
Integrations With Other Systems
Most large organizations don’t run a single piece of software for everything. UKG is built to connect with enterprise resource planning (ERP) systems and other HR platforms. For example, companies using SAP SuccessFactors can integrate employee data and time records between SuccessFactors and UKG, syncing job information, compensation details, and hours worked across both systems. This means an employee’s hire date, pay rate, and department in the HR system automatically appear in the payroll system without someone retyping it.
These integrations matter most for large employers that use one vendor for HR recordkeeping and another for time tracking or payroll. The data flows reduce errors and eliminate the lag that comes from manual transfers between systems.
Additional Tools in the UKG Ecosystem
Beyond core payroll and time tracking, UKG offers several add-on products that connect to the same employee data:
- UKG Wallet: An earned wage access tool that lets employees access a portion of their pay before the scheduled payday, aimed at reducing reliance on payday loans or credit cards between checks.
- UKG Rapid Hire: A hiring tool designed for high-volume, frontline recruiting where employers need to fill many positions quickly.
- UKG Talk: A workplace communication platform that keeps messaging tied to the same system where schedules and shifts live.
- UKG Beacon: Rewards and recognition software for employee engagement programs.
These tools are optional and sold separately, but they all feed into the same employee profile. An employer using the full suite can manage hiring, scheduling, pay, communication, and recognition from one platform.
How to Access Your Kronos Account
If your employer uses UKG, you’ll typically receive login credentials during onboarding. Access is usually through a web browser at a company-specific URL, or through the UKG mobile app. Your HR department or manager can provide the exact link, since each organization has its own login page. From there you can view pay stubs, check your schedule, request time off, and update your tax withholdings or direct deposit information. If you’re locked out, the self-service portal includes options to reset your password and security questions without submitting a help desk ticket.
