US payroll taxes and the contractor question
US payroll has two failure modes. One is administrative — missing a deposit deadline. The other is structural, and considerably more expensive: calling an employee a contractor.
The classification question
Whether a worker is an employee or an independent contractor is decided by the substance of the relationship, not by what the agreement calls them or what both parties would prefer.
The analysis weighs several dimensions:
- Behavioural control. Do you direct how, when and where the work is done? Do you provide training and set the method?
- Financial control. Who provides the tools? Can the worker realise a profit or loss? Do they work for others?
- Nature of the relationship. Is it open-ended? Are benefits provided? Is the work central to your business?
A person who works full time on your core product, using your equipment, to your schedule, exclusively, is an employee whatever the contract says.
Why misclassification is so expensive
Getting it wrong means back payroll taxes — both the employer and employee portions — plus penalties and interest, potentially across several years.
It compounds because it is rarely one person. A business that classifies one role as contractor has usually classified the whole category that way, so a single determination reaches everyone in it.
And it does not stop at tax. Employment law exposure — benefits, protections, entitlements — runs alongside on its own track.
We prepare the schedules and bookkeeping, and a licensed US professional signs where the law requires it.

Withheld payroll taxes must be deposited on a schedule determined by your payroll size, which for larger employers can be semi-weekly.
Two points. The schedule is assigned, not chosen — assuming monthly when you are on semi-weekly produces late deposits from day one. And late deposit penalties apply even where the amount is correct and the return is filed on time.
Paying people outside the US
For a Pakistan-based founder this is often the more relevant question.
A non-US person performing services entirely outside the United States is a different analysis from a US-based worker. The W-8 series documents the payee's foreign status and supports the treatment.
Collect it before the first payment. Chasing tax documentation from someone already paid is a familiar and usually unsuccessful exercise, and the reporting obligation sits with you.
Use a provider
Payroll is high frequency, high penalty and highly automatable. Multi-state withholding, deposit schedules and year-end reporting are exactly what a payroll provider exists to handle.
The cost is modest against a single missed deposit cycle, and it removes the category of error that comes from doing this manually alongside running a business.
Separate payroll calculation, deposit and filing
For each pay run, retain gross wages, pretax items, federal income-tax withholding, employee and employer Social Security and Medicare amounts, state and local deductions, net pay and employer costs. Depositing money does not file the quarterly return, and filing the return does not prove the deposit was timely. Reconcile all three to the general ledger.
Classify workers before the first payment and register in every required jurisdiction. Build a calendar for deposit frequency, Forms 941 or 944 as applicable, unemployment filings, W-2 delivery and state reports. When payroll software changes, reconcile year-to-date wage and tax bases employee by employee so limits are not restarted or deductions duplicated.

Questions people also ask
What is the difference between an employee and a contractor?
It turns on the degree of control and independence in the relationship, not on what the contract calls the person. Behavioural control, financial control and the nature of the relationship are all weighed, and the label alone carries little weight.
What happens if I misclassify someone?
Back payroll taxes, penalties and interest, potentially for multiple years, plus exposure under employment law. It is the most expensive routine mistake a small US employer makes.
Do I withhold payroll tax for a contractor in Pakistan?
A non-US person performing services outside the United States is a different analysis from a US worker. Documentation on a W-8 series form establishes the position, and getting it before payment is far easier than afterwards.
How often do payroll deposits have to be made?
On a schedule determined by your payroll size, which can be as frequent as semi-weekly. The schedule is assigned rather than chosen, and depositing late attracts penalties even if the amount is right.
Should I run payroll myself?
Most small businesses use a payroll provider. Deposit schedules, multi-state withholding and year-end reporting are the kind of high-frequency, high-penalty work that automation handles better than a spreadsheet.
