State Income Taxes Withheld
Generally, states require quarterly state withholding reports to be filed reporting state income taxes withheld from employee's wages. This is not required in states that don't have an income tax imposed on individuals (e.g., Nevada). Check with your state.
State Unemployment Taxes (SUTA)
Generally, state unemployment taxes are paid quarterly, by remitting them with the quarterly state unemployment tax return.
SUTA is an employer tax. Most states do not withhold SUTA tax from an employee's wages. However, currently, Alaska, New Jersey, and Pennsylvania withhold unemployment taxes from employees' wages.
Check your state's requirements.
Annual State Income Tax Reconciliation
Your state may require an annual reconciliation of state income taxes withheld. The amount of income taxes actually paid for the year are reconciled with the amounts that were withheld. The state normally provides a form for this. Check with your state.
Trust Fund Taxes
Trust fund taxes include income taxes and the employee's share of FICA taxes (social security and Medicare taxes) withheld from salaries and wages.
Make sure you turn these taxes over to the government! If you don't, you can be held personally liable for them. In other words, you have no limited liability protection when it comes to these taxes; not even bankruptcy will get you out of paying them.
