Gross to net
Take an illustrative semi-monthly pay run for a small team, in round numbers. The income tax figures depend on each employee’s W-4 and state, so treat them as placeholders:
The employee’s side ends at net pay: gross wages less everything withheld or deducted. Every amount withheld is still owed to someone, the IRS, the state, the 401(k) plan or the insurer, and sits as a liability until it is paid.
- Gross wages: $40,000.
- Federal income tax withheld: $6,000.
- Employee Social Security (6.2%): $2,480. Employee Medicare (1.45%): $580.
- State income tax withheld: $1,800.
- 401(k) deferrals: $2,000. Employee share of health premiums: $600.
- Net pay: $26,540.
The wages entry
One entry records the run from the employee’s side: debit Wages and salaries $40,000; credit Cash $26,540 for net pay; credit Federal income tax withholding payable $6,000; credit FICA payable $3,060 for the employee share of Social Security and Medicare; credit State income tax withholding payable $1,800; credit 401(k) payable $2,000; credit Benefits payable $600. The credits total $40,000, the same as the debit.
Split the debit by department, research and development, sales and marketing, general and administrative, with classes or tracking categories, or the functional income statement will show one payroll number nobody can read. Many companies post net pay to a payroll clearing account rather than straight to cash, and clear it when the provider’s withdrawal hits the bank; that makes the bank match easier when the provider debits net pay and taxes separately.
The employer taxes entry
The employer pays its own share on top of gross wages. Social Security at 6.2% and Medicare at 1.45% match the employee’s: $2,480 and $580, $3,060 in total. Federal unemployment, FUTA, is 6% of each employee’s first $7,000 of wages in the year, reduced to 0.6% in most states by the credit for state unemployment tax; on the first run of the year, with eight people paid $5,000 each and nobody yet past $7,000, that is $240. State unemployment is charged at a rate the state assigns to each employer; say $800 here, illustratively.
The entry: debit Payroll tax expense $4,100; credit FICA payable $3,060; credit FUTA payable $240; credit State unemployment payable $800. FICA payable now holds $6,120, both halves of Social Security and Medicare, which is what gets remitted.
Two limits change the figures through the year. Social Security stops once an employee’s wages pass the year’s wage base, $184,500 in 2026, for both the employee and the employer; Medicare has no cap. FUTA and most state unemployment taxes stop once each employee passes their wage base, which is why payroll tax expense is heaviest in the first quarter. Above $200,000 of wages in a year the employer must also withhold the employee’s 0.9% Additional Medicare Tax, which has no employer match.
Benefits and other deductions
Benefits split into two sides. The employee’s share, health premiums, 401(k) deferrals and similar deductions, comes out of gross pay into a liability, as in the wages entry. The employer’s share is the company’s own expense: if the company pays $3,000 toward health premiums for the period, debit Employee benefits $3,000; credit Benefits payable $3,000. When the insurer is paid, debit Benefits payable $3,600, both shares; credit Cash $3,600.
A 401(k) match works the same way: debit 401(k) match expense, credit 401(k) payable, cleared when the money goes to the plan. Pre-tax deductions change how much income tax and FICA are withheld, which the provider calculates; the books simply record what the register says.
Remitting the liabilities
The payroll provider usually pulls the taxes from your bank and deposits them with the IRS and the states on the required schedule. The entry clears the liabilities: debit Federal income tax withholding payable $6,000; debit FICA payable $6,120; credit Cash $12,120. State withholding and unemployment taxes are cleared the same way when they are paid.
At month end every payroll liability should be near zero or explainable by a deposit not yet made, and should tie to the provider’s tax liability report. A FICA payable that grows month after month means withdrawals are being booked to expense instead of clearing the liability, and the expense is being counted twice.
Accruing payroll at month end
Pay periods rarely end on the last day of the month. If the company runs payroll every two weeks and the last pay period of September runs past the 30th, some of the wages paid in October were earned in September. Under accrual accounting they belong to September.
An illustrative case: a two-week period with $40,000 of gross wages, of which three of ten working days fall in September. Accrue 30%: debit Wages and salaries $12,000; credit Accrued payroll $12,000, plus the employer taxes on it. Set the entry to reverse on October 1, so that when October’s payroll posts the full $40,000, only $28,000 net lands in October. Without the accrual, every month’s payroll depends on how many paydays it happened to contain.
Bonuses and commissions earned in the month and paid later are accrued the same way. Accrued vacation may need to be recorded too, depending on your policy and state law; it is the kind of policy question a CPA review should confirm once.
What the payroll provider gives you
Gusto, Rippling, ADP and the others produce the same core reports under different names. They are the source documents the payroll entries are built from and tied to:
The provider calculates and files; it does not know your chart of accounts or your departments, and it does not accrue across month end. Mapping, tie-out and accruals are the bookkeeping, and they are what makes payroll on the income statement agree with the 941 your provider filed.
- Payroll journal or register: gross wages, each withholding, each deduction and net pay, by employee and department.
- Employer tax report: Social Security, Medicare, FUTA and state taxes for the run.
- Tax liability and deposit report: what was withheld, what was paid, what is still owed.
- Benefits and retirement reports: employee and employer shares by plan.
- Quarterly and annual filings: Form 941, Form 940, state returns and W-2s, which should agree with the books.
Common questions
What is the difference between gross pay and net pay?
Gross pay is what the employee earned before anything is taken out. Net pay is what lands in their bank account after federal and state income tax withholding, the employee’s share of Social Security and Medicare, and deductions like 401(k) deferrals and health premiums. The company’s expense is gross pay plus the employer’s own payroll taxes and benefits.
Are taxes withheld from employees a company expense?
No. Withholding is the employee’s money that the company holds and remits to the IRS and the state; it is a liability from payday until it is paid over. Only the employer’s share of payroll taxes, Social Security, Medicare, FUTA and state unemployment, is the company’s own tax expense.
What are the employer payroll tax rates?
6.2% Social Security on wages up to the annual wage base ($184,500 in 2026) and 1.45% Medicare on all wages, matched by the employee. Federal unemployment (FUTA) is 6% of each employee’s first $7,000 of wages, cut to 0.6% in most states by the credit for state unemployment tax. State unemployment rates are assigned to each employer by the state.
What report do I need from Gusto, Rippling or ADP?
Use the payroll provider’s payroll journal or register for the run: gross wages by department, each tax withheld, each deduction, net pay, and employer taxes. Most providers that integrate with QuickBooks Online or Xero can post this summary automatically; it still needs to be mapped to the right accounts and tied out each month.
How are contractors different?
Contractors paid on a 1099 are not on payroll: there is no withholding and no employer tax. Their invoices are booked to a contractor expense account through accounts payable. Treat them the same way in the chart, by department, so their cost lands in the right function.
