State Payroll Tax Calculation

I need reliable, year-round support calculating the state payroll taxes for my small business for fiscal years 2025 and 2026. My in-house software already handles gross-to-net, but I want an expert to verify every state-level rate change, apply the correct withholding formulas, and produce precise per-pay-period figures that I can plug straight into my system.

Scope
• Validate current and upcoming 2025–2026 state payroll tax tables.
• Calculate employer and employee portions for each scheduled pay run (bi-weekly).
• Flag any mid-year legislative updates so I can adjust on time.
• Provide a simple spreadsheet (Excel or Google Sheets) summarizing calculations plus an audit trail I can hand to my accountant.

Acceptance criteria
• Numbers match the official state calculator to the cent.
• Spreadsheet is delivered at least three business days before each payroll date.
• All rate changes are documented with source links to the state’s guidance.

I will supply gross wages, benefit deductions, and employee residency details; you return the finished figures and documentation. Accuracy and timeliness are critical, so please be ready to reference current state statutes and keep me posted on any rule shifts throughout 2025 and 2026.
