When recovering a wage overpayment by deduction the employer must comply with regulations promulgated by the commissioner, and those regulations must include - among other things - provisions governing the size of overpayments covered, the timing, frequency, duration and method of recovery, limitations on the periodic amount recovered, notice to the employee before recovery commences, and a dispute-or-delay procedure of which the employee must be notified before recovery commences. (jurisdiction: New York State, United States, entity_scope: employers recovering wage overpayments from employees under New York State Labor Law Section 193, conditions: the recovery is a deduction to recover an overpayment of wages under paragraph c)

“In making such recoveries, the employer shall comply with regulations promulgated by the commissioner for this purpose, which regulations shall include, but not be limited to, provisions governing: the size of overpayments that may be covered by this section; the timing, frequency, duration, and method of such recovery; limitations on the periodic amount of such recovery; a requirement that notice be provided to the employee prior to the commencement of such recovery; a requirement that the employer implement a procedure for disputing the amount of such overpayment or seeking to delay commencement of such recovery; the terms and content of such a procedure and a requirement that notice of the procedure for disputing the overpayment or seeking to delay commencement of such recovery be provided to the employee prior to the commencement of such recovery.”

The Labor Commissioner's Office states that an employer can lawfully withhold amounts from an employee's wages only in three situations: when required or empowered to do so by state or federal law; when the deduction is expressly authorized in writing by the employee to cover insurance premiums, benefit plan contributions or other deductions not amounting to a rebate on the employee's wages; or when a deduction to cover health, welfare or pension contributions is expressly authorized by a wage or collective bargaining agreement. The page attributes this to Labor Code Sections 221 and 224.

The page states that Labor Code Section 224 prohibits any deduction from an employee's wages that is not either authorized by the employee in writing or permitted by law, and that an employer who resorts to self-help does so at its own risk, because an objective test is applied to determine whether the loss was due to dishonesty, willfulness or a grossly negligent act.

Not yet fully established from an authoritative source

  • Establish the accounting treatment that distinguishes an amount withheld from an employee for a benefit plan, which is held as a liability owed onward, from the employer's own share, which is an expense of the period the coverage relates to. (not established; below the required authority class)
  • Establish the timeliness requirement for remitting amounts withheld from employee pay as retirement plan deferrals, and the class of consequence that follows a late remittance, and establish how amounts withheld from employee pay as deferrals are distinguished from the employer's own contribution or match, and whether the same remittance requirement attaches to each. (partly established)
  • Establish what governs recovering an under-deducted employee benefit contribution from later pay - whether a catch-up deduction is permitted, what authorisation or notice it requires, and how state wage rules constrain it, and establish what governs the opposite correction - returning an over-deducted contribution to the employee, and carrying an amount the employee still owes as an arrears balance rather than deducting it at once. (partly established)
  • Establish what a benefit carrier or plan administrator invoice is expected to contain - participant-level detail, the coverage period, and separately identified retroactive adjustments - to the level needed to support a participant-level reconciliation, the period an invoice covers relative to the period in which it is issued, how the plan's own terms for a waiting period, a tier change, a mid-period termination and unpaid leave determine what is billed for a participant, and on what basis the carrier issues a retroactive credit or rebill. (partly established)
  • Establish the evidence that constitutes a completed benefit liability reconciliation - the supporting schedule, the named cause for each variance, and the preparer and reviewer record, the source records the tie was performed against, retained so the reconciliation can be re-performed, and the point at which an unexplained residual must be escalated as a finding rather than accepted as immaterial. (not established)
  • Establish the reconciliation as a tie between three independent populations - billed enrolment, payroll deductions taken, and the employer share - and show that the reconciling item is always the difference between two of those, never a single unexplained total. (not established)
  • Explain how the invoice coverage period and the pay periods whose deductions fund it are aligned before any comparison, and how deductions taken on a different cadence from the billing cadence are normalised. (not established)
  • Require the comparison to be made participant by participant against the invoice's enrolment detail, and explain why a totals-only tie hides offsetting errors. (not established)
  • Set out the causes to test in order - enrolment change that never reached payroll, tier change, waiting period, mid-period termination, retroactive carrier adjustment, an extra or missed deduction, unpaid leave - and how each is confirmed from a specific record rather than inferred. (partly established)
  • Show the ledger structure that makes this reconcilable: the employee withholding held as a liability, the employer share expensed in the period it relates to, and the invoice payment clearing the liability while recognising the employer portion. (not established; below the required authority class)
  • Explain how the residual balance in the benefit liability account is read and aged, and establish the point at which an unexplained residual becomes the reportable finding rather than a rounding item. (not established)
  • Distinguish the corrective paths once a cause is known - a catch-up deduction from future pay, an employee arrears balance, a refund to the employee, a carrier credit or rebill - and establish which corrections must be made in payroll rather than by a ledger entry. (partly established)
  • Address retirement plan invoices and remittances on their own terms: separating employee deferrals from employer contributions or match, and establishing the timeliness expectation that attaches to remitting amounts already withheld from employee pay. (partly established)
  • Specify the evidence retained for a completed reconciliation - the invoice, the deduction register, the enrolment change records supporting each variance and the written explanation - so the tie can be re-performed later. (not established; below the required authority class)
