Payroll is the act in which an employer pays their employees. Payroll includes salaries, wages, deductions, bonuses, and net pay. Typically, payroll will be on a weekly, biweekly, or monthly schedule. Some of the considerations when running payroll includes how a company will:
Processing payroll is one of the most important parts to running a U.S. business. Payment for labor is often the largest cost to a business and can amount to 70%+ of its total expenditure.
The hiring of every new employee requires the restarting of the payroll lifecycle. The Payroll Lifecycle can be broken down into four buckets:
Having a repeatable, scalable payroll process will save your business time and money. The HR or payroll leader should be able to document your organizations approach for the following key functions:
There are many challenges to running a compliant and efficient payroll process in the United States. Because the employer will be held accountable for any payroll missteps, some of the things to be extra aware of are:
The employers are responsible for collecting employee information and data to ensure their pay and withholdings are correct. Employers withhold employee's share of taxes, pay the employer’s share of the taxes, send those taxes to the IRS, and report the employee’s earnings to the SSA. Employers must withhold federal income tax, social security tax, Medicare tax, state income tax, and local income tax from employees’ paychecks. In addition, the company must pay the employer’s share of social security and Medicare taxes and make federal and state unemployment insurance contributions on their behalf.
Unemployment insurance tax is a joint federal-state system. In most states, only the employer is responsible for paying the federal and state unemployment taxes that support the unemployment insurance system. Employees working in Alaska, New Jersey, or Pennsylvania, though, are required to pay part of the state unemployment insurance tax. Like the other taxes discussed above, the unemployment insurance tax in these states is withheld directly from the employees’ paychecks. The federal unemployment tax is not withheld from employees’ wages.
Employees are required to provide HR with all of their proper and accurate information and data when they are hired. This includes their name, SSN, number of dependents, and their preferred withholdings for taxes.
At year-end, employees will receive payroll information from their employer in the form of a W-2. This details an employee’s withholdings and the amount of money earned and taxes paid over the past year so they can complete their taxes.
The payroll and accounting departments will typically handle payroll within a company. Depending on the size and makeup of the company this can differ. The HR department will typically collect and enter all of the employee data for the payroll process.
Payroll data can be used when:
Those in charge of payroll will need to be aware of the United States’ unique approach to payroll & withholding. If a company is not using a payroll product which includes a gross-to-net feature, they need to understand how to deduct federal income taxes, state income taxes, Social Security, and Medicare insurance, as mentioned above. These are basic withholdings that will need to be taken from the workers' checks.
It's also important to develop a reliable, efficient system for the payroll process regardless of the payroll lifecycle at your business. You need to be sure that enough employees are using the right tools to handle the payroll and ensure that your employees are paid on time.
The United States Department of Labor is responsible for setting the labor standards, while the Internal Revenue Service, or IRS, enforces the federal tax laws. Employees in the U.S. can report their Employers for violating the Department of Labor’s labor and wage laws.The IRS requires employers to withhold, report, and pay payroll taxes following their regulations. State and local governments also pass their own payroll legislation.
Mistakes that trigger compliance audits/fines include: failing to complete/re-verify I-9/E-Verify for employees, misclassifying employees as contractors (or vice versa), not withholding appropriate taxes, failing to report new hires, not paying minimum wage or overtime, failure to provide required pay-stubs, missing child-support garnishments for contractors, incorrect 1099 or W-2 filings. Fines vary but can be significant (e.g., more than $28,000 per ineligible W-2 hire).
If your business model, client demands, or regulatory environment changes and you decide to transition workers from 1099 to W-2 (or the reverse in rare cases), you need a solution that handles new onboarding (tax/wage/eligibility paperwork), modifies pay/deductions workflows, updates your pay-roll tax engine, and adjusts your billing/invoicing logic. A flexible platform built for both classification types ensures you avoid patchwork systems. Zeal supports both W-2 and 1099 at scale.
For on-demand marketplaces and staffing operations where speed matters (shifts change, high turnover), you should aim to complete onboarding (document collection, eligibility check, tax forms) in minutes, not days. A streamlined and unified mobile/remote onboarding flow helps. Zeal supports mobile remote I-9/E-Verify and e-signature onboarding to accelerate this.
Many general payroll vendors are built for “one employer, one location, one schedule” scenarios — not high-volume, many-workers, multi-location gig models. They often lack: onboarding workflows tailored to high-volume staffing, automated classification support (W-2/1099), multi-jurisdiction tax engines, fast payouts (instant, paycards), billing and receivable integration, and worker self-service portals. By contrast Zeal is built for staffing/gig scale.
In on-demand or staffing operations where a worker may live in one state, work in another, or travel across multiple jurisdictions in a week, compliance becomes significantly more complex. You must manage: minimum wage requirements differing by state/city, overtime rules by jurisdiction, tax withholding/residency/work-state issues, unemployment/worker‐comp jurisdictional issues. A robust solution will dynamically capture worker location info at onboarding and at each shift, determine applicable rules, and automate pay accordingly.
For W-2 employees you must ensure:
Also ensure you capture worker’s multiple work locations or shifts if they cross jurisdictions (for tax/withholding purposes).
At minimum you should:
You may also want to collect a Form I-9 from your workers and have their employment eligibility verified through E-Verify. While this is not required we are seeing that enforcement of employment eligibility varies by administration.
Worker classification hinges on the “employee vs independent contractor” analysis. Under U.S. Department of Labor (DOL) final rule effective March 11, 2024 (regulation at 29 CFR 795), six key factors apply:
In staffing/gig firms you must apply this test consistently and document your decision. Misclassification can lead to compliance violations and major fines (for example, for missing minimum wage or overtime protections when a worker should have been W-2).
For staffing companies and marketplaces working with gig or on-demand labor, the onboarding phase is a critical risk point. Key risks include: mis-classifying a worker (i.e., treating a W-2 employee as a 1099 contractor), failing to complete a compliant I-9 / E-Verify check for W-2 workers, not collecting correct tax forms (W-4 for employees, W-9 for contractors), lacking documentation of worker certifications or licenses, and failing to collect or monitor multijurisdictional data (worker’s residence, work location, shift locations) that will affect tax & wage compliance. Additionally, companies can use the onboarding process to mitigate other compliance risks such as displaying labor posters and onboarding to faster payment methods. By automating onboarding workflows you reduce manual errors, accelerate worker start-time, and build a more compliant foundation.
