## TL;DR
Fix this in Gusto by acting on the exact problem first: in Gusto, compare the state withholding on the filing against the payroll register withholding by employee for that state, correct the employee state tax setup or work state that is wrong, and regenerate the filing before submitting it. Do not rerun the whole payroll workflow unchanged, because the same inputs produce the same failure. Prove the fix on one employee first, then rerun the full scope and reconcile the results against the payroll register.

## Use this when
- The operation in Gusto fails with this exact problem: Gusto payroll tax filing error state withholding amount incorrect.
- The same failure repeats on retry with unchanged inputs.
- A payroll run, tax filing, garnishment check or pay close is blocked until this is resolved.

## Not for this skill when
- The notice is a platform outage from the vendor. Resolve that first, then return here if this problem remains.
- The payroll completes and you only disagree with a pay policy decision such as a rate or a benefit rule. That is a policy change, not this failure.

## Steps
1. Reproduce the failure on one named employee in Gusto and record the full problem text plus the employee, pay period or filing involved. Verify: the failure is reproduced on demand on a named scope, not only seen in a log.
2. Apply the specific fix for this problem: in Gusto, compare the state withholding on the filing against the payroll register withholding by employee for that state, correct the employee state tax setup or work state that is wrong, and regenerate the filing before submitting it. Verify: the single failing employee now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check neighbouring employees, pay groups or filings that share the same pay code, deduction setup or import, because this class of failure rarely affects only one employee. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in Gusto on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
5. Compare the result against the source of truth, the payroll register, the tax filings or the employee records, so a silent partial success is caught. Verify: values match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the employee or run record so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

## Variant phrasings

### Gusto payroll tax filing error state withholding amount incorrect
The verbatim form searchers paste from the console, report or run log. Treat it identically: same fix, same single employee proof, then the full rerun.

### How to fix - Gusto payroll tax filing error state withholding amount incorrect
The how to phrasing for the same failure in Gusto. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### Gusto troubleshooting for this failure
The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

## Why it happens
Gusto files withholding from the accumulated register amounts, and an employee set up in the wrong work state or with a stale withholding election files an incorrect state total until the setup is fixed and the filing regenerated.

## Edge cases
- The employee was terminated, transferred or given a rate change after the failing run started. Refresh the employee state and reapply the fix against the current values, not the values from the failed run.
- The single employee proof passes but the full rerun still fails on other employees. Treat each remaining failure as its own scope, because a shared pay code or import can hide more than one cause.
- The source systems disagree on the correct value. The payroll register governs amounts paid, the tax filings govern amounts reported, and the employee record governs setup; record which source won and why.

Compatibility: Gusto at current versions, plus the payroll system, time system or general ledger the query names; no extra tooling beyond access to the payroll register, tax filings and employee records needed to verify results.
