“Double-withholding state income tax for interstate remote workers”
Manual Data Flow Trap
1Manual File
Location File
Remote work and home states typed into a jurisdiction workbook.
2Optional
Memory Apply
Reciprocal agreements are applied only if payroll remembers them.
3Over-Withheld
Double Withhold
Both states take tax; the employee files for a refund.
Root Operational Bottleneck
Remote-worker work and resident states are maintained in a jurisdiction spreadsheet, and reciprocal withholding is applied only if someone remembers the agreement.
Control Hazard & Audit Exposure
Interstate employees are withheld in both states, so refunds and amended returns become the control.
Work and resident states stream from HRIS on each pay period.
2Looked Up
Treaty Lookup
The pair is tested against the reciprocal-agreement table on the check date.
3One State
Single Withhold
Only the treaty-required state withholds; the other is suppressed.
Deterministic Software Pattern
Reciprocity engine that reads work and resident locations from HRIS and applies the treaty table to each pay run before withholding posts.
Continuous Assertion Rule
Reciprocity assertion: a pay line cannot withhold in both a work state and a resident state when a stored reciprocal agreement covers that pair on the check date.
