 "prompt": "An employee moves from Oregon to Washington mid-month but works remote for a New York company. Which taxes apply and from when?",
 "system": "You are a payroll assistant at a US company. Answer the request.",
 "model": "claude-opus-5-5",
 "response": "# Oregon to Washington Move, Remote Employee of a New York Employer\n\n**General rule:** State payroll taxes follow **where the employee physically works**, not where the employer is located. Switch everything **on the first day the employee works from Washington**. If the move falls mid-pay-period, split that period's wages by workdays in each state.\n\n## 1. Federal (no change)\n- Federal income tax withholding\n- Social Security and Medicare (FICA)\n- FUTA. The wage base is cumulative for the year.\n\n## 2. Oregon: through the last day worked in Oregon\n| Tax | Notes |\n|---|---|\n| **Oregon income tax withholding** | Stops after the move. The employee files as a part-year resident. |\n| **Oregon statewide transit tax** (0.1%, employee) | Stops after the move. |\n| **Paid Leave Oregon** (1% total; 60% employee / 40% employer if 25+ employees) | Stops after the move. |\n| **Oregon SUTA** and the **Workers' Benefit Fund** assessment | Stops after the move. |\n| **Local taxes, if applicable** | **TriMet or Lane Transit** employer payroll tax if the employee worked inside those districts. **Metro SHS and Multnomah County PFA** withholding if you withhold these for the employee. All stop after the move. |\n\n## 3. Washington: starting the first day worked in Washington\nWashington has **no state income tax**, but these apply:\n\n| Tax | Notes |\n|---|---|\n| **WA Paid Family & Medical Leave** | Premium is split between employee and employer. The employer share applies if you have 50+ employees in WA. Check the current-year rate. |\n| **WA Cares Fund** (long-term care) | 0.58% employee-paid, unless the employee holds an approved ESD exemption letter. |\n| **WA unemployment insurance (SUTA)** | Employer-paid. Under the localization test, coverage moves to WA. Oregon wages paid earlier in the year can generally count toward the WA taxable wage base. |\n| **WA L&I workers' compensation** | Industrial insurance is hour-based, partly withheld from the employee. Private carriers can't cover this, so you must report to WA L&I. |\n\n**Registration:** If this is your first WA employee, register with **WA ESD** (UI, PFML, WA Cares) and **L&I** before the first WA payroll. A WA employee can also create business nexus, which may trigger B&O tax registration with the Department of Revenue. Flag this to your tax team.\n\n## 4. New York",
