Gross pay is not what the employee takes home — and not what the job costs
Tell a worker their salary is $60,000 and you have told them only one of three different numbers. The first is gross pay — the $60,000 the contract promises. The second is net pay, the smaller amount that actually lands in the bank account after deductions. The third, larger than either, is what the *employer* truly spends to keep that person on the payroll, because the company owes its own taxes on top of the wage. Earlier in this rung you saw that book income and taxable income are different numbers; payroll is where you discover that even "a $60,000 salary" is really three numbers in a trench coat.
The gap between gross and net comes from [[tax-withholding|withholding]] — money the employer holds back out of the worker's own pay and forwards to the government on their behalf. The worker still earns the full gross; they simply never touch the withheld slice. Crucially, that withheld money was never the company's to keep. The instant it is deducted, the company is holding cash that belongs to the tax authority, which makes it a [[payroll-liabilities|payroll liability]], not an expense. Confusing the two is the single most common beginner error here, so pin it down now: withholding is the employee's tax, merely passing through the employer's hands.
What gets withheld from the employee
Three kinds of money typically come out of a worker's gross pay. First, income tax withholding — an estimate of the annual income tax the worker will owe, chipped off each paycheque so the government collects steadily through the year rather than in one painful lump at filing time. Second, the employee's share of social insurance. In the United States this is FICA, which funds Social Security and Medicare; the worker pays 6.2 percent of wages for Social Security (up to an annual wage cap) and 1.45 percent for Medicare, for 7.65 percent in all. Third, any voluntary deductions the worker has chosen — a retirement contribution, health-insurance premium, union dues — which are not taxes at all but follow the same mechanical path off the top.
Walk one paycheque through. A worker earns $5,000 gross this month. Income tax withholding takes, say, $800. FICA takes 7.65 percent, or $382.50. The worker net pay is $5,000 − $800 − $382.50 = $3,817.50 in the bank. The employer's wage *expense* for this person, though, is the full $5,000 — the worker genuinely earned every dollar; the deductions are simply where that pay was routed. The $1,182.50 held back is not income to the company and not an expense; it is cash the company is now holding in trust for two government agencies, owed and payable within days.
What the employer owes on top: the match, FUTA, and SUTA
Now the second half — the [[payroll-taxes|payroll taxes]] the employer pays from its *own* pocket, which never appear on the worker's pay stub. The biggest is the employer FICA match: for every dollar of Social Security and Medicare the employee pays, the employer pays the same 7.65 percent again. The worker's $382.50 is quietly matched by another $382.50 from the company. So Social Security and Medicare are jointly funded — half visibly deducted from the worker, half invisibly borne by the employer — which is why the program's true tax rate on a wage is 15.3 percent, not the 7.65 percent a worker sees.
Two unemployment taxes complete the employer's bill, both paid entirely by the company with nothing withheld from workers. FUTA — the federal unemployment tax — and SUTA — the state version — together fund the system that pays benefits to people who lose their jobs. They apply only to a low slice of each worker's wages (a base of a few thousand dollars per worker per year, after which they stop), so in dollar terms they are small beside the FICA match. SUTA carries a twist worth knowing: its rate is *experience-rated*, meaning an employer that lays people off often pays a higher rate, while a stable employer pays less — the tax gently penalizes churn.
Add it up for our $5,000 worker. The employer's *own* taxes are the FICA match of $382.50 plus, say, a small FUTA and SUTA charge of $50 combined while the worker is still under the wage base — call it $432.50. That is real money the company spends purely to employ this person, on top of the $5,000 wage. The true cost of the hire this month is therefore closer to $5,432.50 than to $5,000, and that gap is exactly the employer's payroll-tax burden — invisible on the pay stub, very visible on the income statement.
Booking it: two journal entries, kept honest
Payroll lands as two distinct journal entries, and keeping them separate is what makes the collector-versus-payer distinction visible. The first records the wages the employee earned: debit Wages expense for the full $5,000 gross, then credit each thing that slice of pay is owed to. Cash (or wages payable) gets the net $3,817.50; the withholdings become liabilities — income tax payable $800, FICA payable $382.50 — because the company is holding that cash for the government. Notice the expense is the gross, never the net: the worker earned $5,000, and the debits and credits balance precisely.
(1) Record the employee's earned wages
Dr Wages expense ............... 5,000.00 (gross pay earned)
Cr Income tax payable ......... 800.00 (employee's tax, held)
Cr FICA payable ............... 382.50 (employee's 7.65% share)
Cr Cash (net pay) .......... 3,817.50 (what hits the bank)
(2) Record the EMPLOYER's own payroll taxes
Dr Payroll tax expense ......... 432.50 (a real company cost)
Cr FICA payable ............... 382.50 (employer's matching 7.65%)
Cr FUTA / SUTA payable ........ 50.00 (unemployment taxes)
The FICA payable account now holds 765.00 -- both halves -- all
owed to the government, and remitted as one payment days later.The second entry books the employer's own burden: debit Payroll tax expense $432.50, credit the matching FICA payable $382.50 and FUTA/SUTA payable $50. This is where the company's real extra cost finally hits the income statement. And note what just happened in the FICA payable account — it now holds $765, the employee's $382.50 plus the employer's $382.50, both flowing to the same agency. When the company later remits, a third entry debits those liability accounts and credits cash, clearing the debt and confirming these were never expenses but obligations passing through.
If payroll spans a period-end — workers earned wages in December but get paid in January — the employer's payroll-tax expense is accrued right alongside the wages, exactly as you learned in the adjustments rung. The matching principle insists the company's share of FICA, FUTA, and SUTA belongs in the period the labour was used, not the period the cheque clears. So an accrued payroll-tax liability gets raised at year-end, keeping the cost of employing someone glued to the revenue their work helped earn.
Why this is a legal obligation, not just bookkeeping
Payroll compliance carries a weight ordinary accounting errors do not, and the reason is the trust money. When a company withholds an employee's income tax and FICA, it is holding cash that legally belongs to the government from the moment it is deducted. Failing to remit it on time is not a bookkeeping slip — in many systems it is treated as misappropriating funds held in trust, and the penalties are severe: stiff late charges, interest, and in serious cases personal liability for the owners or officers who controlled the money. The government is far harsher about *withheld* taxes than about a late corporate tax return, precisely because that money was never the company's to begin with.
Beyond timely remittance, employers must file periodic payroll reports, deposit on a fixed schedule, and issue each worker an annual wage summary they need to file their own income tax. Misclassifying a worker as an "independent contractor" to dodge the employer match — a common temptation, since it erases the 7.65 percent FICA cost — is policed aggressively, because it shifts the whole burden onto the worker and starves the social-insurance funds. None of this is discretionary. Payroll is one of the few corners of accounting where a clerical mistake can become a legal liability with the owner's name on it.
Step back and the shape of payroll is clear: every paycheque is a small tax-collection machine the employer is legally compelled to operate. The worker's gross pay splits into net cash plus withheld trust money; the employer adds its own match and unemployment taxes as a genuine expense; the liabilities sit briefly on the balance sheet and then flow to the government on a strict timetable. Get the split right — collector here, payer there — and both the journal entries and the law fall into place. Next in this rung we turn to how all these taxes, payroll included, shape the gap between the profit a company reports and the income it is actually taxed on.
