How to Organize Mississippi Estate Tax Documents Before Your CPA Meeting

Your first meeting with a CPA or estate attorney after a death in Mississippi will cost $250 to $450 before any substantive work begins. That fee covers the professional's time to review what you brought, identify what you missed, and explain what happens next. If you walk in with a grocery bag of unsorted mail and a vague sense of what the deceased owned, a significant portion of that billable time goes to inventorying paperwork -- not preparing returns. At $120 to $250 per hour for a CPA, or $150 to $300 per hour for a Mississippi estate attorney, every hour spent sorting documents is an hour you could have handled yourself for free.

The fix is straightforward: organize the documents before the meeting so the professional spends their time on the work only they can do -- preparing returns, advising on elections, and identifying tax-saving opportunities you would miss on your own. This post walks through exactly what to gather, how to organize it, and what most executors forget.

The Documents You Need, Organized by Category

The mistake most executors make is gathering documents randomly -- pulling whatever they find first and hoping the CPA can make sense of the pile. Professionals think in categories. When you organize the same way they do, the meeting becomes productive from minute one.

Legal Authority Documents

These establish that you have the right to act on behalf of the estate:

• Letters Testamentary or Letters of Administration -- issued by the Chancery Court after probate is opened. This is the document that gives you legal authority to act for the estate. Banks, brokerages, and the IRS all require it.
• Certified death certificates -- get at least 10 copies. Every financial institution, insurance company, and government agency will want an original. Running out mid-process means ordering more from MSDH at $15 each with a multi-week wait.
• The will (if one exists) -- the original, not a photocopy. The CPA needs to understand the distribution scheme to advise on tax elections.
• EIN confirmation letter -- the estate's Employer Identification Number from the IRS (Form SS-4 or the online confirmation). Most executors do not realize the estate needs its own tax ID separate from the deceased's Social Security number. If you have not applied for one yet, do it before the meeting at irs.gov -- it takes 10 minutes online.

Tax History

• Prior year federal returns (at least 2-3 years of Form 1040)
• Prior year Mississippi returns (Form 80-105) -- see our post on Mississippi Form 80-105 filing requirements for what this form covers
• Any estimated tax payment vouchers the deceased was using
• Prior year property tax statements for all real estate

Income Documents (for the year of death)

Everything the deceased received from January 1 through the date of death:

• W-2s and 1099s -- wages, Social Security (SSA-1099), pensions, dividends (1099-DIV), interest (1099-INT), brokerage statements (1099-B), rental income records
• K-1s from any partnerships, S-corps, or trusts the deceased participated in
• Business income records if the deceased was self-employed

Property and Asset Records

• Real estate deeds and current assessed values for all properties
• Date-of-death appraisals -- this is critical for establishing step-up in basis. The stepped-up basis saves heirs capital gains tax when they eventually sell inherited property, but it requires documented fair market value as of the date of death. If the deceased owned a home, rental property, or land, get appraisals done proactively. Waiting until a sale years later and trying to reconstruct what the property was worth at death is expensive and imprecise.
• Vehicle titles and approximate values
• Bank and brokerage statements showing balances as of the date of death (not the most recent statement -- the date-of-death statement specifically)
• Life insurance policies and beneficiary designations
• Retirement account statements (IRAs, 401(k)s, pensions) with beneficiary designations

Retirement Accounts (Separate Category for a Reason)

Retirement accounts are where executors most often create accidental tax liability. The CPA needs to see:

• Beneficiary designation forms (not just account statements) -- these override the will and determine how distributions are taxed
• Account type -- traditional IRA, Roth IRA, 401(k), 403(b), pension -- each has different tax treatment for inherited accounts
• Required Minimum Distribution records -- if the deceased was over 73, they may have had an RMD for the year of death that was not yet taken. A missed RMD triggers a 25% penalty. Your CPA needs to know the status.

Debts and Liabilities

• Mortgage statements with current balances
• Credit card statements showing outstanding balances
• Medical bills from the final illness
• Any outstanding loans (auto, personal, business)
• Medicaid claims -- if the deceased received Medicaid benefits, the Mississippi Division of Medicaid may assert an estate recovery claim. Your CPA and attorney need to know this upfront.

Prior Estate Tax Returns and Elections

• Form 706 (federal estate tax return) -- even if the estate is below the federal exemption ($13.99 million in 2026), filing Form 706 may be advisable to elect portability of the deceased spouse's unused exemption. This is a "use it or lose it" election that must be filed within 2 years of death.
• Form 80-699 (Mississippi Statement of Heirship) -- required for claiming refunds under $500 owed to the deceased by Mississippi

The Documents Most Executors Miss

Experienced CPAs say the same documents are missing from virtually every first meeting. Knowing this list in advance saves you a follow-up appointment:

The EIN. The estate is a separate taxpayer. It needs its own Employer Identification Number. Without it, the CPA cannot file the estate's fiduciary returns. Apply online at irs.gov before your meeting.

Multiple certified death certificates. Executors order two or three and run out within the first week. Financial institutions keep the originals. Order 10 to 12.

Form 81-110 awareness. Here is the Mississippi-specific trap most executors fall into: if the estate earns any income during probate -- rental income from the deceased's property, dividends from stocks that have not been distributed, interest on bank accounts -- the estate itself owes Mississippi fiduciary income tax on Form 81-110. Most executors do not know this form exists until their CPA tells them, usually after a year of unreported estate income has accumulated. See our breakdown of Mississippi fiduciary income tax returns for the full picture.

Federal fiduciary return (Form 1041). The federal counterpart to Form 81-110. If the estate earns more than $600 in gross income during administration, this return is required.

Date-of-death appraisals. Step-up in basis is one of the most valuable tax benefits available to heirs, but it requires documentation. If you do not have a professional appraisal of real property as of the date of death, the IRS can challenge the basis you claim. Get appraisals done now, while comparable sales data is fresh.

Creditor claim publication timing. This is not a document per se, but your CPA and attorney need to know whether you have published the creditor notice in a local newspaper. Mississippi law gives creditors 90 days from publication to file claims. The strategic move is to publish early -- the sooner the 90-day clock starts, the sooner you can make final distributions. Your CPA needs this timeline to plan the estate's cash flow.

How to Organize It for the Meeting

Physical organization matters. A labeled folder system beats a stack of papers every time:

1. Use tabbed folders or a binder with dividers -- one section per category above (Legal Authority, Tax History, Income, Property, Retirement, Debts, Prior Returns)
2. Put a summary sheet on top -- one page listing: the deceased's full legal name, SSN, date of death, date of birth, domicile, the executor's name and contact information, the estate's EIN, the attorney's name (if retained), and the Chancery Court case number (if probate is open)
3. Flag what you know is missing -- do not pretend you have everything. Write a list of documents you could not locate. The CPA would rather see "could not find 2024 state return" on your list than discover it is missing 30 minutes into the meeting.
4. Bring originals and copies -- the CPA may need to retain copies. Do not hand over your only death certificate.

Who This Is For

• Executors or administrators who have been appointed by a Mississippi Chancery Court and are preparing for their first meeting with a CPA or estate attorney
• Surviving spouses handling the deceased's final tax obligations and needing to understand what a CPA will require
• Adult children managing a parent's estate who have never dealt with estate tax filings and want to avoid paying professional rates for document organization
• Out-of-state executors unfamiliar with Mississippi-specific forms (80-105, 81-110, 80-699) who need to know what to gather before traveling for the meeting

Who This Is NOT For

• Executors of estates with contested wills or active litigation -- your attorney is directing the process and will tell you what to bring
• Estates under active IRS audit -- do not organize and present documents without your tax attorney's guidance on what to disclose and in what sequence
• Families who have not yet opened probate or obtained Letters Testamentary -- you need legal authority before most financial institutions will release the statements you need to gather
• Situations where the death is under investigation and the estate is not yet in the executor's control

The Tradeoffs: Guide vs. Winging It vs. Full-Service Estate Planner

Winging it (no preparation)

You walk into the CPA meeting with whatever documents you found in the deceased's filing cabinet. The CPA spends the first 1-2 hours inventorying what you brought, identifying gaps, and sending you home with a list of what to retrieve. You come back for a second meeting. At $120-$250 per hour, the sorting and gap-identification alone costs $250-$500 -- before any returns are prepared.

Using a guide to prepare

The Mississippi Final Tax & Estate Tax Guide includes a CPA Document Checklist organized by the exact categories above -- legal authority, tax history, income, property, retirement, debts, prior returns. It also includes a Master Deadline Calendar (so you know which filings are urgent), a Form Decision Tree (which returns apply to your estate), a Step-Up in Basis Worksheet (so you arrive with date-of-death values documented), and a Spousal Rights Reference Card. At , the guide costs less than 15 minutes of CPA time and saves multiple hours of professional billing. The CPA opens your folder, sees everything organized by category, and starts doing CPA work immediately.

Hiring a full-service estate planner

A full-service estate settlement firm handles everything -- document gathering, return preparation, filing, correspondence with the IRS and Mississippi DOR. Fees run $3,000 to $10,000 depending on estate complexity. This makes sense for large or complicated estates. For a straightforward Mississippi estate -- particularly one where no state estate tax is owed (Mississippi repealed its estate tax in 2004) -- you are paying premium rates for organizational work you can do yourself. The guide-plus-CPA combination covers the same ground at a fraction of the cost.

FAQ

What forms does a Mississippi estate need to file?

The answer depends on the estate's circumstances. At minimum: the deceased's final individual Mississippi return (Form 80-105) and final federal Form 1040, both covering January 1 through the date of death. If the estate earns income during administration, add Form 81-110 (Mississippi fiduciary) and federal Form 1041. If the estate exceeds the federal exemption or the surviving spouse wants to elect portability, add Form 706. For refunds under $500 owed to the deceased, Mississippi requires Form 80-699 (Statement of Heirship).

Does Mississippi have a state estate tax?

No. Mississippi repealed its estate tax in 2004 and has not reinstated it. There is no state inheritance tax either. However, federal estate tax still applies to estates exceeding the federal exemption ($13.99 million in 2026), and Mississippi estates still owe state income tax on the deceased's final return and on any income earned by the estate during probate. For the full breakdown, see our post on Mississippi estate tax.

How many death certificates do I need?

Order 10 to 12 certified copies. Every bank, brokerage, insurance company, and government agency handling a claim will require a certified copy, and most keep the original rather than returning it. At $15 per copy from MSDH with multi-week processing times, running out mid-process creates delays at the worst possible time.

What is step-up in basis and why does it matter for my CPA meeting?

When someone dies, the tax basis of their property resets to its fair market value on the date of death. This means heirs who later sell the property only pay capital gains tax on appreciation after the death, not from the original purchase price. But to claim this benefit, you need documented proof of what the property was worth when the person died. Getting date-of-death appraisals for real estate, and bringing date-of-death brokerage statements for securities, gives your CPA the data needed to establish the stepped-up basis properly.

What happens if the estate earns income during probate?

This is the Mississippi-specific issue most executors miss. If the estate receives rental income, dividends, interest, or any other income during the period of administration, it must file a Mississippi fiduciary income tax return (Form 81-110) and a federal fiduciary return (Form 1041) if gross income exceeds $600. The estate pays tax on this income at its own rates, under its own EIN. Bring records of any estate income to your CPA meeting -- do not assume it gets reported on the deceased's final personal return.

Should I get the EIN before or after meeting with the CPA?

Before. The estate's Employer Identification Number is required for every fiduciary tax return the estate will file. Applying takes 10 minutes online at irs.gov. If you show up without one, the CPA cannot prepare fiduciary returns and may need to pause the engagement until you obtain it. It costs nothing. Do it before the meeting.

The Mississippi Final Tax & Estate Tax Guide includes the CPA Document Checklist, Master Deadline Calendar, Form Decision Tree, Step-Up in Basis Worksheet, Small Estate Affidavit Worksheet, and Spousal Rights Reference Card -- everything discussed in this post as standalone, printable tools. At , it costs a fraction of one billable hour and ensures your CPA spends time preparing returns, not sorting through your paperwork. The Mississippi probate process post covers the broader estate administration timeline if you need context on where tax filings fit into the overall sequence.
