First response: stop the problem from growing
Keep every page of each notice and the envelope, record the response date, and identify the tax form and period involved. At the same time, confirm that current payroll is being reported and deposited correctly. Resolving older quarters while new liabilities continue to accumulate usually makes the situation harder.
Do not assume a payroll provider filed a return or made a deposit merely because money left the operating account. The IRS explains that an employer using a payroll service provider generally remains responsible for federal employment-tax duties if the provider fails to perform them. Review the IRS guidance on outsourcing payroll.
- Preserve notices, envelopes, payroll reports, payment confirmations, and provider communications
- Identify every affected entity, tax form, quarter, and response deadline
- Confirm that current payroll returns and deposits are being handled correctly
- Restrict changes to records and account access until discrepancies are understood
- Seek tax and legal advice promptly if interviews, personal assessments, insolvency, or enforcement are involved
