Connecticut Annual Reconciliation of Withholding

What the Connecticut Annual Reconciliation of Withholding is and why it matters

The Connecticut Annual Reconciliation of Withholding is an employer tax document used to reconcile wages and state income tax withheld for a calendar year with tax payments and quarterly returns previously submitted to the Connecticut Department of Revenue Services. Employers report totals for wages, withheld Connecticut income tax, adjustments and credits, and reconcile differences so the state can verify proper withholding and payment. The reconciliation supports W-2 reporting to employees and helps the employer meet state withholding obligations and recordkeeping requirements.

Why completing the reconciliation accurately benefits your payroll operations

Accurate annual reconciliation prevents late-filing penalties, reduces audit risk, and ensures employees receive correct withholding credits. It also supports year-end payroll closeout and ties employer deposits to reported withholdings, which simplifies future payroll audits and state correspondence.

Why completing the reconciliation accurately benefits your payroll operations

Who typically prepares and submits the Connecticut Annual Reconciliation

Employers, payroll administrators, and third-party payroll providers carry primary responsibility for preparing the annual withholding reconciliation.

  • Small business owners balancing payroll and reporting for a single location.
  • Payroll teams at mid-market companies reconciling quarterly deposits and year-end reporting.
  • Accounting firms and payroll vendors preparing reconciliations for multiple employer clients.

Accurate preparation reduces downstream corrections to W-2s and mitigates state inquiries; ensure the person completing the form has access to payroll ledgers and deposit records.
