Without it, I can't responsibly explain why any individual employee's net pay changed, and I don't want to guess at causes.\n\n**What to send (pasted text or CSV is fine; redact SSNs)**\nFor each of the 40 employees, ideally for both the prior and current run:\n- Employee ID or initials, pay frequency, and pay period dates\n- Gross pay, broken out by earnings code (regular, OT, bonus, commission, PTO, retro, etc.)\n- Pre-tax deductions (401k, health, HSA, FSA)\n- Taxes (federal, state, local, FICA, SUI/SDI)\n- Post-tax deductions (garnishments, Roth, loan repayments, etc.)\n- Net pay\n- Any changes logged between runs (W-4/state withholding updates, rate changes, benefit events, terminations or new hires)\n\n**What I'll do with it**\nI'll run a variance breakdown per employee, attributing the net pay change to specific drivers, and group the 40 into categories.\n\n**Common drivers I'll look for**\n- **Gross pay changes:** overtime swings, bonus or commission, retro pay, PTO payout, unpaid leave, a different number of work days or hours, a rate change, or a partial period for new hires or terminations\n- **Tax changes:** a W-4 or state withholding update, supplemental rate withholding on bonuses (22% federal flat), Social Security wage base cap reached for high earners, or a local or state tax change\n- **Pre-tax deduction changes:** open enrollment or qualifying life events, 401k percentage changes, or deductions skipped or doubled up (for example, a 3-paycheck month)\n- **Post-tax deduction changes:** a new or ended garnishment, loan repayment, or Roth contribution change\n- **Timing and error flags:** a missed or duplicate deduction, a manual check or off-cycle run included, or a prior-period correction or reversal\n\n**Output format**\nA table with employee, prior net, current net, $ and % change, primary driver, and a flag for \"expected\" or \"needs review.\" I'll also note anything that looks like an error rather than a legitimate change.\n\nPlease paste the data and I'll start the analysis.",
