Name the document that brought you here
Before calling, identify whether your question concerns a joint-return balance, a refund offset, or the financial evidence behind a payment discussion. Have the tax year and notice reference available. A short description helps begin the conversation without first sharing the complete joint return or private household identifiers.
Confirm the proposed next task
Call (855) 494-5639 with the household tax question you want addressed. Ask what review would be useful, which documents are necessary, and how an authorized exchange should happen. If a service is proposed, request an explanation of responsibilities and fees and keep a note of the agreed scope. Ask who would handle any required account response, and keep a refund-allocation question tied to the actual return and notice.
