What the result means

A positive refund position suggests an estimated refund. A negative result suggests additional state tax may be due.

Refund Position = State Tax Withheld + State Credits + Additional Payments - Estimated State Tax

This calculator estimates position only and does not apply official state refund rules.

Example calculation

For $4,200 withheld, $3,500 estimated tax, $300 credits, and $200 additional payments, the estimated refund is $1,200.

Tips for better results

  • Compare withholding against estimated tax before year-end.
  • Track refundable and nonrefundable credits separately.
  • Use the result to identify likely refund or amount owed.
