Talking with adult children about the family's tax and estate documents

Parents often put off talking with adult children about family assets because the conversation feels like it is about money, fairness, and expectations. Those are family matters, and no tax preparer should referee them. But there is a narrower conversation that is easier to have and harder to skip: what tax and estate documents exist, where they are, who the children will need to call, and what the children are already responsible for on their own returns. Children who know those facts are less likely to miss a filing, lose a basis record, or learn about a trust from an IRS notice.

This post covers what adult children should know about the family's tax and estate documents, and what the parents can share without discussing amounts or plans they want to keep private. It is not family counseling, it does not recommend how much to share, and it is not estate planning or legal advice.

Separate the facts from the numbers

Most families can share the existence and location of documents without sharing values. A child can know that a trust exists, who the trustee is, and that the trust files a Form 1041, without knowing its balance. A child can know who the family's preparer and estate attorney are, without seeing the will. Starting with facts, not figures, lowers the stakes and covers most of what a child will need in an emergency.

What children should know now

Their own filings

Adult children are often already part of the family's tax picture, sometimes without knowing it:

• K-1s in their name. If a child owns an interest in a family partnership or LLC, they receive a K-1 and must report it on their own return, often in more than one state. They need to know when to expect it and that it may arrive after April 15.
• Trust distributions. A distribution from a non-grantor trust can carry taxable income to the beneficiary, reported on a Schedule K-1 from Form 1041.
• Gifts they received. Gifted assets carry the donor's basis. A child who sells gifted shares needs the parent's basis record, or the gain may be overstated.
• Custodial accounts that became theirs. UTMA and UGMA accounts become the child's at the age set by state law. The income is reported on the child's return. For younger dependents, the kiddie tax applies to unearned income above $2,700 for 2026.
• 529 plans. If the child is the account owner or beneficiary, they need the Form 1099-Q records and the qualified expense records for the years they withdraw.

Who to call

List the preparer, estate attorney, financial advisor, insurance agent, and any trustees, with phone numbers. Note which of them the parents have authorized to talk to the children. A preparer cannot discuss a parent's return with a child without the parent's written consent, and a Form 8821 or 2848 is needed for the IRS to talk to anyone on the parents' behalf.

Where documents are

The location of originals of wills, trusts, powers of attorney, health care directives, deeds, entity documents, and recent tax returns. Who has keys or access. Where passwords are stored.

What children will need if a parent dies or becomes incapacitated

A child who serves as executor, trustee, or agent under a power of attorney inherits a set of tax tasks with deadlines:

• The parent's final Form 1040, due April 15 of the year after death.
• Form 1041 for the estate if it has gross income of $600 or more, and for any trust that becomes irrevocable at death.
• Form 706, the federal estate tax return, due nine months after death (with a six-month extension available), if the estate exceeds the filing threshold, or to elect portability of the unused exclusion to a surviving spouse. For 2026 deaths, the basic exclusion amount is $15,000,000.
• State estate tax returns where applicable. New York's exclusion for 2026 deaths is $7,350,000, and several states are lower.
• Date-of-death valuations for assets, which set the new basis for heirs under IRC Section 1014. These are the most important records a child will ever receive from a parent's estate, and they are easiest to get promptly.
• Form 56, notifying the IRS of a fiduciary relationship.

Children do not need to know how to do these tasks. They need to know the tasks exist and who to call.

For a parent who becomes incapacitated, the agent under a durable power of attorney needs a separate tax authorization. A general durable power of attorney may be accepted by the IRS in some cases, but filing a Form 2848 for a representative, or having the parent sign one in advance, is more reliable.

What parents can choose to keep private

Values, beneficiary percentages, the reasons behind a plan, and future gifts are the family's to share or not. Nothing in the tax system requires parents to disclose them to children while living. A child named as trustee will eventually see the trust's terms, and a child who receives a K-1 will see their own share. Parents who want to keep values private can still make the facts above available.

A one-page handout for adult children

• Names and contact information for the preparer, estate attorney, financial advisor, and trustees.
• A list of entities and trusts the child has an interest in, with the forms they will receive.
• The location of original estate documents.
• Who is named as executor, trustee, and agent, and who is the backup.
• Where basis records are kept for any gifts made to the child.
• A note that tax documents should be sent to their own preparer by an encrypted method, not plain email.

Some parents worry that sharing even the facts will invite questions about amounts. A simple line helps: "This list tells you what exists and who to call. The details are in documents you will see when you need them." Most adult children accept that, especially when the handout also helps them with their own filings this year.

The scored diagnostic

Score each item 0, 1, or 2. Zero means missing. One means partial or out of date. Two means current and documented.

Item	0, 1, or 2
Children know which K-1s and 1099s to expect in their own names
Children who received gifts have the basis records
Children know who the preparer and estate attorney are
Advisors have written consent to talk to named children
Children named as fiduciaries know their role
Location of original documents is shared
Backup fiduciaries are named and know it
Date-of-death valuation is understood as a priority task
Passwords and account access have a documented plan

A total of 15 to 18 means the children could manage an emergency. A total of 9 to 14 means a few facts need sharing. Below 9, start with the one-page handout.

Illustrative: a K-1 nobody mentioned

Illustrative: Parents gave each of their three adult children a 10% interest in a family real estate LLC several years ago. The LLC's preparer sends K-1s to the parents' address, and the parents put them in a drawer. Two children have never reported the income. One child receives a CP2000 notice after the IRS matches the K-1.

The fix is not a discussion about the value of the LLC. It is a list: each child's K-1 goes to the child, each child's preparer receives it, and the LLC updates its records with the children's current addresses. The children may need to amend prior years, possibly in more than one state.

How often to revisit

Once a year is enough for most families, and the annual tax and estate document check-in is a natural place for it. Revisit sooner after a death, a divorce, a move, a new entity, or when a child turns 18 or 21 and custodial accounts or trust terms change. Each of those events changes what a child receives, files, or may be asked to sign.

Who owns what

The parents decide what to share. The estate attorney explains the documents to anyone the parents choose. The preparer handles each person's own returns, with consent before discussing anyone else's.

Next step: make the one-page handout for your adult children, leaving out any numbers you want to keep private, and review it with them once a year.
