US Payroll Tax Compliance Advisor
Budget: $250 – $750 USD
My team is building an in-house HRMS with fully integrated U.S. payroll, and I want to be absolutely certain every tax rule is baked in correctly from day one. I need a seasoned consultant who can walk us through the full spectrum of Federal and State payroll-tax requirements, covering both employee and employer withholding, plus all regular and year-end filings.
Beyond explaining the rules, the engagement should translate compliance into system logic so our developers can embed each calculation, threshold, and deadline directly into the platform.
Deliverables I have in mind
• A clear compliance matrix mapping every Federal and State tax requirement to its corresponding field or calculation in the HRMS
• Step-by-step withholding setup guidelines for both employee and employer taxes
• A filing calendar (regular and year-end) with form names, due dates, and e-file specifications
• A short best-practice brief on integrating payroll APIs or service bureaus, if applicable
• Final review session to validate that our implemented workflows meet current IRS and state standards
I’m open to collaborating remotely and can provide sandbox access to the system so we can work through the logic together. Let me know your relevant experience with U.S. payroll tax, any notable platforms you’ve integrated with (ADP, Paychex, QuickBooks, etc.), and how soon you could begin.
