Hiring a remote employee in another state: the cost and compliance checklist
Check work location, registrations, withholding, unemployment and insurance before adding a remote employee to payroll.
Updated October 2026 ยท 9 minute read
A remote hire can expand the skills available to a small business, but the employee's work location changes more than their mailing address. Payroll withholding, unemployment insurance, workers' compensation and employment rules may need attention in a state where the business has never operated.
Start before the offer becomes a firm start date. Ask where the person will actually work, whether they will regularly work elsewhere and who can authorise a location change. A payroll provider can help process wages, but selecting a state in software does not itself create every required registration or settle the legal questions.
| Item | Lower salary scenario | Higher salary scenario |
|---|---|---|
| Assumed annual salary | $40,000 | $60,000 |
| Employer Social Security at 6.2% | $2,480 | $3,720 |
| Employer Medicare at 1.45% | $580 | $870 |
| Published PA foreign registration fee, if applicable | $250 | $250 |
| Specified additions above salary | $3,310 | $4,840 |
| State UI, insurance, benefits and service charges | Obtain applicable figures | Not included |
Checklist 1: confirm location and business registration
Record the usual work address and any expected travel or regular work in another state. Separate residence from work location where they differ. The facts can affect withholding and unemployment localisation in different ways. Do not assume that all employment taxes follow a single location rule.
Check whether the business must register as an out of state entity with the work state's business agency. Pennsylvania's official guidance for hiring remote employees explains foreign registration and publishes a $250 filing fee. It also discusses a physical Pennsylvania address or a commercial registered office provider. That guidance is a specific state example, not a national fee schedule.
Business tax nexus needs its own review. An employee's activities may create obligations beyond payroll, but the answer depends on the tax and facts. Do not claim that every remote employee automatically creates every type of tax liability. Ask an adviser to assess the actual work, customers and business activities.
Checklist 2: open the right payroll and unemployment accounts
Check state income tax withholding registration, unemployment registration and any local payroll requirements. The home office state and employee work state can have different rules, including reciprocal arrangements in some cases. Reciprocity for income tax does not automatically resolve unemployment or workers' compensation.
Use the state's unemployment localisation guidance to determine where wages belong. Confirm the assigned rate and taxable wage base when the account is established. The SUTA guide explains why a percentage alone is not enough to calculate cost. Do not import an unverified new employer rate from a generic national table.
California EDD's employer guidance provides an example of registration and reporting duties: a business generally must register within 15 days after paying more than $100 in wages in a calendar quarter. California also requires new employee reporting within 20 days of the start date. These are California examples, not deadlines to reuse in another state.
Federal payroll obligations remain. IRS Publication 15 explains withholding, employer Social Security and Medicare, and FUTA. State expansion does not replace those rules. Check that payroll records show employer costs separately from employee withholding so the hiring budget does not include taxes funded by the worker.
Checklist 3: confirm insurance and employment rules
Tell your workers' compensation insurer about the actual work state and duties before employment begins. Ask whether the existing policy covers the location or needs an endorsement or separate arrangement. A remote office is still a workplace, and a state policy or classification can differ from your headquarters assumptions.
Review applicable wage and hour requirements, paid leave, notices, final pay and expense reimbursement rules. Some obligations depend on locality or workforce size. Build the checklist for the actual location rather than copying a policy designed for your home state and assuming remote staff are exempt.
Provide a workable time recording process for covered hourly employees. Required meetings, training and support tasks can be paid working time under Department of Labor rules. Working from home does not turn an hourly role into unpaid project work or remove overtime obligations.
Check data access and equipment arrangements. Decide what the business supplies, how support works and how equipment is recovered at the end of employment. Use real supplier and shipping quotes. This guide does not invent a national laptop, internet or home office reimbursement allowance.
What drives the cost up or down
The first employee in a new state can trigger setup work that later hires reuse. Separate initial filing fees and advice from recurring payroll, insurance and benefit costs. Charging the whole setup project to every additional employee would overstate the marginal hiring cost.
The employee's duties can be as important as the address. Sales, installation, field work and ordinary administration may raise different business and insurance questions. A job title does not capture every relevant activity. Give advisers a factual description and update it when responsibilities change.
More locations create more maintenance. Keep a register of accounts, return deadlines, notices and policy renewals. A business that handles filings internally has staff time costs, while a provider may charge a fee. Obtain the actual provider terms instead of assuming every additional state costs a standard monthly amount.
Location changes can interrupt a compliant setup. Agree that employees tell the business before moving or regularly working elsewhere, then review the change before it happens where possible. This is an administrative control, not a promise that permission alone determines which law applies.
Make a decision using a complete checklist
Compare the additional operating cost with the value of the hire. A candidate in another state might fit the role better, but a lower salary is not the whole saving. Include verified state charges, insurance changes, payroll administration and any genuine benefit differences before making the decision.
If considering a PEO or EOR, confirm the provider's actual role and supported locations. Outsourcing payroll does not automatically remove business registration or tax nexus questions. Review the contract and responsibilities using the PEO and EOR guide rather than treating the service name as a legal conclusion.
Use the true cost of an employee calculator to organise annual employment categories and the cost per hire calculator for recruitment and onboarding. Keep the interstate setup allowance distinct. When a required quote or state assessment is missing, leave that line marked for verification instead of substituting an unsupported market average.
Worked example: a first Pennsylvania remote hire
Assume an employer outside Pennsylvania plans a remote administrative hire working there. Use 2 illustrative salary scenarios: $40,000 and $60,000 annually. These are assumed offers, not published wage estimates. Both are below the applicable Social Security wage limit for the simple calculation shown.
IRS employer Social Security and Medicare rates produce $3,060 at the lower salary and $4,590 at the higher salary. Adding Pennsylvania's published $250 foreign registration filing fee, where required, gives specified additions of $3,310 to $4,840 above salary. The salary plus those listed items is $43,310 to $64,840 in the first year.
This is deliberately incomplete. It excludes state unemployment, FUTA, workers' compensation, benefits, registered office provider charges, payroll services and professional advice. It also does not decide whether the employer's particular activities require other registration or taxes. Obtain those figures before committing to a complete hiring budget. The filing fee is an initial charge, not an assumed annual renewal amount.
Frequently asked questions
Do I just withhold tax in the employee home state?
Not automatically. Residence, actual work location, reciprocity and the tax involved can matter. Confirm income tax withholding and unemployment localisation separately with the relevant agencies or adviser. A single payroll setting does not settle every interstate obligation.
Does a payroll provider register my business everywhere?
Only if that service is explicitly included and completed. Ask who files each registration, which account numbers are issued and who maintains returns. Payroll processing, business registration and business tax advice are different tasks and may have different owners.
Is Pennsylvania registration always $250 annually?
The cited official guidance publishes a $250 foreign registration filing fee. This example treats it as an initial fee where registration applies, not an annual recurring charge. Other filings, service providers and continuing obligations require separate verification.
Can I avoid the issue by calling the person a contractor?
Only use a contractor arrangement when it genuinely meets the applicable classification rules. A label or invoice does not determine status. Misclassification can create tax and employment exposure. Compare the real working relationship rather than using the label to bypass state obligations.
Can the employee move states after starting?
A move can change payroll, insurance and employment requirements. Have the person notify the business in advance and review the new work location. Update relevant accounts and policies where required. Permission from the employer alone does not prevent another state law from applying.
