Payroll sounds simple until a company hires its first person outside the US or Canada. Then it gets complicated fast.
Remote payroll touches taxes, currencies, and local labor law all at once. A nearshore hire in Mexico does not run through the same system as a hire down the street.
Set it up right, though, and the payoff is big. Nearshore hires often cost 40 to 60 percent less per role, with the same hours and quality. Want to keep that saving? Set up your payroll and taxes the right way, and this guide shows you how.
This article covers what payroll tax actually is, and how to calculate it. It also covers outsourced payroll services and hr and payroll outsourcing. Things change once nearshore talent enters the picture.
By the end, you will know where payroll gets tricky, and how the right outsourcing setup clears it up.
Payroll used to be simple, because work itself was simple to locate. A company paid people in one country, in one currency, under one set of rules. The rules were easy because everyone sat in the same place.
Forbes points out that this model no longer fits how most companies actually work. Remote work is now a normal, permanent part of the workforce. Hiring today is location-agnostic, meaning talent and geography are no longer tied together.
That same Forbes piece cites data from the US Bureau of Labor Statistics. More than 35 million Americans teleworked in the first quarter of 2024 alone. That is roughly one in five workers, on an average day.
This shift changes what payroll actually is. Forbes describes payroll as something closer to a treasury function now, not a back-office task. It touches multiple currencies, banking systems, and tax regimes at once, especially for companies hiring across borders.
Adding a layer to this, payroll is not just a cost center. It is a strategic function that shapes compliance, trust, and financial planning at the same time. Payroll data can reveal real patterns, like a department quietly running heavy overtime month after month.
Put together, this means payroll deserves more attention than most companies give it. This is especially true the moment a team hires outside its home country.
Payroll tax is money withheld from an employee's paycheck, plus a matching amount the employer pays. Together, this funds specific government programs, mainly Social Security and Medicare in the US.
This system runs under a law called FICA, the Federal Insurance Contributions Act. It applies to nearly every employee paycheck, regardless of company size.
Payroll tax is different from income tax. Income tax funds general government spending. Payroll tax funds specific programs tied directly to the worker, like retirement and healthcare benefits later in life.
Every country runs its own version of this system. A nearshore hire in Mexico pays into a different set of programs, under different rules entirely. This catches many US and Canadian companies off guard. It is a common first mistake when hiring across borders.
In the US, the combined FICA rate is 15.3% for 2026. This splits evenly between employer and employee, 7.65% each.
That breaks down into two parts. Social Security tax runs at 6.2% each, up to a wage base of $184,500 for 2026. Medicare tax runs at 1.45% each, with no wage cap at all.
High earners face one more layer. Wages above $200,000 carry an additional 0.9% Medicare tax, paid only by the employee, with no employer match.
Calculating payroll tax follows a simple structure, even though the rules around it get complex fast.
Start with gross wages for the pay period. Apply 6.2% for Social Security, until the employee hits the annual wage base. Apply 1.45% for Medicare on the full amount, with no cap. Add the 0.9% additional Medicare tax only once wages cross the $200,000 mark for the year.
The employer then matches the Social Security and standard Medicare portions. This doubles the total contribution, without doubling the employee's paycheck deduction.
This calculation gets harder once state taxes, benefits deductions, and multi-state employees enter the picture.
Once payroll gets complicated, most companies consider outsourcing payroll instead of handling it in-house.
When a specialist team takes over this work, your internal team no longer has to track local tax filings at all.
This frees up real time. Instead of manually cross-checking spreadsheets, finance leaders can focus on work that actually grows the business.
Outsourcing gives companies access to specialized expertise and mature processes. Building that same capability internally is often expensive and slow.
The tipping point often comes down to a simple test: does payroll bleed into your weekends? Have you hired your first employee outside your home state or country? If either is true, it is time to offload the work.
Pricing varies depending on what a company needs. Basic outsourced payroll services often run under $100 a month per employee. Add HR or benefits help, and the price goes up. Full-service plans can cost more than $100 a month per employee.
Nearshore hiring adds a layer that most domestic payroll outsourcing does not cover.
A nearshore employee in Mexico needs local tax withholding, local benefits, and compliance with Mexican labor law. None of this runs through a standard US payroll system. This is where HR and payroll outsourcing becomes less optional and more essential.
Forbes frames this well. Cross-border payments intersect with HR, finance, treasury, and banking systems all at once. A company managing this alone needs real expertise in each of those areas, in more than one country.
This is exactly the gap an Employer of Record model closes. An EOR partner runs payroll, tax filing, and compliance for the nearshore hire directly. The hiring company still controls the work and the team. It does not need to build a whole international payroll system from scratch.
This setup matters most for companies without a dedicated HR or finance team. It also helps companies that outsource local payroll but have no way to manage pay and taxes for team members abroad.
No, and this is one of the most common wrong ideas about outsourcing payroll.
Smaller companies often assume outsourcing only makes sense at scale, once headcount justifies the cost. In practice, the opposite is often true.
Picture a five-person startup. The founder runs payroll herself, late on a Sunday night, between everything else. She is not a tax expert, she's just the only person available to do it.
One quarter, she misses a filing deadline she did not know existed. The penalty that follows costs more than a full year of outsourcing would have.
This is the real risk for small teams. A small company without an HR or finance department has the most to lose from a payroll mistake. One missed filing or incorrect tax can trigger real penalties, with no internal team to catch the error early.
A big company has a whole department to spot these problems. A small one often has one tired person, guessing.
The cost math surprises people too. Outsourcing payroll for a few hundred dollars a month is often far cheaper than hiring someone in-house to do the same work. A full-time payroll person costs a salary, benefits, and payroll taxes on top.
For a small team, that is rarely worth it. Outsourcing is not a luxury here. It is usually the more affordable option from day one.
There is a quieter cost, as well. Think about the hours a founder spends on payroll each month. Those are hours not spent on customers, product, or growth.
For a small team, the founder's time is the most valuable resource in the building. Spending it on tax filings is an expensive way to save a few dollars.
The real question is not company size. It is whether payroll is eating time that should go toward growing the business instead.
Everything above points to one practical conclusion. Payroll gets complicated fast once a company hires across borders, and outsourcing is usually the simpler path.
Remoto Workforce solves exactly this.
We act as the Employer of Record for every nearshore hire. This means Remoto handles local payroll, tax withholding, and compliance directly. The hiring company keeps full control over daily work and management, without touching the paperwork behind it.
This removes the exact gap covered above. You do not need to research Mexican labor law. You do not need to set up local tax filings. And you do not need to run a second payroll system next to your US one.
The model runs month-to-month, with no upfront fees. A company can start with one nearshore hire and see how payroll works, before committing to more.
Reading about payroll tax and outsourcing costs only goes so far. The real question is what this looks like for your own team, your own headcount, and your own current setup.
Use our cost calculator to compare your current costs against a nearshore hire. No payroll or compliance headaches to manage. It takes a few minutes, and it gives you real numbers instead of general ranges.
Payroll complexity rarely goes away on its own. Whether you keep payroll in-house, outsource it locally, or add nearshore talent, the right setup depends on real numbers, not guesswork. Start with the calculator, and go from there.
