HNI Families: Why a Letter of Instruction Can Simplify Estate Planning

Healthcare Provider Update: HNI Corporation offers health insurance coverage to its U.S. employees through medical, dental, and vision plans, along with prescription benefits. The company provides Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) with employer contributions, as well as company-paid life and disability insurance. Preventive care and wellness programs are also included. HNI Corporation Healthcare costs in the United States are projected to continue rising through 2026, with insurers proposing significant premium increases for Affordable Care Act (ACA) plans. A recent analysis found that ACA insurers are seeking a median premium increase of 15% for 2026, marking the largest hike since 2018. This surge is attributed to factors such as the anticipated expiration of enhanced premium tax credits, rising medical costsincluding expensive medications and increased hospital staysand a shift in the risk pool towards higher-cost enrollees. Without the renewal of enhanced subsidies, out-of-pocket premiums for ACA marketplace enrollees could increase by more than 75% on average. Click here to learn more

Important Lessons

Estate planning documents like a will and a revocable trust are important, but they might not give your family all the information they need to handle your affairs when you pass away, especially for HNI employees with complex benefits.

In addition to an estate plan, a letter of instruction can offer your loved ones more information about your assets and personal preferences.

A letter of instruction can contain additional details, such as burial plans and the placement of essential documents, but it should not conflict with your estate planning documents.

Your loved ones might not know who to call, where to find your assets, or how to recognize reputable creditors if something were to happen to you today. By providing clear, supplemental guidance, a letter of instruction can help reduce the stress and work involved in the estate administration process.

A Letter of Instruction: What Is It?

A letter of instruction is an informal document outlining your assets and last wishes, sent to an executor, personal representative, or family members. It adds helpful information not included in legally binding estate planning documents like a will or revocable trust. For HNI employees managing multiple retirement and savings plans, a letter of instruction can help simplify administration for family members, even though it is not legally required.

Since this letter is informal, it can be updated without consulting an attorney as circumstances change over time. It can contain supplementary information that supports your estate plan, but it should not contradict anything in your legal estate planning documentation.

How to Compose an Instructional Letter

Funeral Plans

You might provide information about your preferred funeral or burial type, funeral home, clergy member, music, speakers, or tribute. You can also include details about pre-paid or pre-arranged funeral or burial plans and where related paperwork is located. Some people also provide biographical details—something HNI retirees can include for clarity.

Crucial Records

You can note the location of your Social Security card, recent bank account statements, deeds, titles, mortgage documents, important records, and estate planning documents. Some individuals also indicate where to find recent tax returns, which may help identify assets or income sources. If these documents are stored in a lockbox or vault, providing access instructions may be helpful.

Contact Details for Financial Representatives

The names and contact information for bankers, tax preparers, lawyers, insurance agents, real estate agents, and financial advisors can be included in the letter. These professionals can assist with background information, asset identification, account transfers, and final tax filings.

Details of the Assets

You can list your assets’ locations, titling, identifying details, and current values. This may include real estate, stock certificates, savings bonds, annuities, time shares, bank accounts, brokerage accounts, retirement accounts, company interests, safe deposit boxes, life insurance, and personal belongings with monetary or sentimental value.

Computer Files and Online Accounts

You may wish to list your digital files and accounts and designate a successor in your estate planning documents to manage them, since state and federal laws may limit access without written approval. For HNI retirees who store retirement and benefits information online, this documentation may help reduce challenges.

Details of Debt

You can include information regarding your debts, such as account numbers, balances, statements, and lender contact details.

Beneficiary Details

The beneficiaries listed in your estate plan, along with their contact details, may be included in the letter. This makes it easier for an executor to locate and communicate with those who will receive assets—an important step for families with HNI retirement accounts.

Pets

You can specify who you want to care for your pets and any specific instructions if your estate documents do not mention them. You may also include your veterinarian’s contact information.

Distribution List for Personal Property

Some states allow individuals to draft a separate document listing specific items of tangible personal property and their intended recipients, as long as the will references the list. Even in states where this is not legally binding, a letter of instruction can still guide your executor and help minimize disagreements.

Private Notes and Clarification of Goals

Some people include private notes or explanations for their decisions regarding inheritance or financial principles. Although not legally binding, these notes can help prevent misunderstandings.

What Does a Letter of Instruction Not Need to Include?

A letter of instruction should not repeat information already found in your estate planning documents. It is intended to provide additional details only.

It also should not be used to make changes to legally enforceable estate documents. Informal updates are not binding and may create conflicts.

Where to Store Your Instruction Letter

You can keep a copy of the letter with your estate planning papers, provide one to your lawyer, or place it somewhere your family is likely to look first. You can also share a copy with your executor and discuss it with them if you feel comfortable. Updating the letter each year is useful as assets and personal information change—particularly for HNI employees with evolving retirement benefits.
