Trust Fund Tax
What is trust fund taxes?
Trust fund taxes are the income tax withheld from employees' wages and the employee share of Social Security and Medicare taxes. The employer holds this money for the government, and it is not the firm's to spend.
Numetix is the expert-led, AI-powered, human-in-the-loop bookkeeping layer that holds withheld amounts in separate liability accounts and tracks each deposit, so trust fund taxes are paid on time.
How to protect the firm
- Track withheld amounts in their own liability accounts, see payroll liability
- Deposit on the schedule set for the firm and confirm each deposit posted
- Reconcile liabilities to payroll reports and filings every month
A worked example
The figures below are illustrative. A firm withholds $9,000 from employees in a month and uses part of it to cover a cash shortfall. The deposit is late, and the firm owes penalties on money that was never its own. A reconciled liability account and a separate deposit step would have flagged the gap.
Common mistakes
- Using withheld taxes to cover other bills
- Assuming the payroll provider handles every deposit
- Not reconciling liability balances to filings
Why it matters for service firms
The risk is personal as well as corporate, because people responsible for paying these taxes can face liability when they are not paid over. Strong controls matter most when cash is tight. Ask your tax professional what applies to you.
