Separate

Tax is not the whole balance.

Interest, penalties and payments can move on different timelines.

Evidence

Keep the latest status.

A paid receipt and an IRS notice answer different questions.

Limit

Escalate complex balances.

Large penalties, collection notices or appeal deadlines need professional review.
