IRS Form 706 Schedule L Guide: Estate Losses & Expenses

1. Introduction – What is Form 706 (Schedule L)?

IRS Form 706 (Schedule L), officially titled Schedule L – Net Losses During Administration and Expenses Incurred in Administering Property Not Subject to Claims, is a supporting schedule attached to IRS Form 706 (United States Estate Tax Return). Governed by the Internal Revenue Service (IRS), it allows estate executors to claim deductions for specific property losses and non-probate administrative expenses.

During the administration of an estate, unforeseen events can occur. Property may suffer physical damage from natural disasters, or non-probate assets—such as those held inside a Revocable Living Trust—may require legal, accounting, and trustee services to distribute to heirs.

Under Sections 2054 and 2053(b) of the Internal Revenue Code, Schedule L permits executors to deduct uncompensated casualty or theft losses as well as administrative expenses incurred in managing non-probate assets, reducing the net taxable estate on Form 706.

2. Purpose of the Form

The primary purpose of Schedule L is to provide a dedicated schedule for claiming tax deductions for uncompensated property losses and non-probate trust administration fees.

Schedule L solves two distinct problems in estate tax administration. First, under Section 2054, if estate property is destroyed by a hurricane, fire, or theft while the estate is being settled, taxing the original pre-loss property value would be unfair. Schedule L allows the net uncompensated loss to be deducted.

Second, Schedule L addresses non-probate property under Section 2053(b). While probate asset expenses belong on Schedule J, non-probate assets (such as trust property reported on Schedule G) also incur administrative fees. Schedule L provides the legal mechanism to deduct administrative costs spent on non-probate assets.

3. Who Needs to File This Form

Schedule L must be completed and attached to Form 706 whenever an estate incurs deductible casualty/theft losses during settlement or pays administrative expenses for non-probate assets included in the gross estate.

An estate executor should list items on Schedule L for either of the following categories:

• Uncompensated Casualty and Theft Losses (Section 2054): Losses arising from fires, storms, floods, shipwrecks, earthquakes, vandalism, or theft occurring after the decedent’s death and before final estate settlement, to the extent not compensated by insurance.
• Non-Probate Trust Administration Expenses (Section 2053(b)): Trustee fees, legal fees, accounting costs, and appraisal expenses incurred in collecting, settling, or distributing property *not subject to claims* (such as Revocable Living Trusts, Irrevocable Trusts, or joint tenancy property).

4. Who Is Exempt / Not Required to File

Schedule L is restricted to specific casualty loss events and non-probate administrative expenses. Other expenses belong on different schedules.

You should NOT list items on Schedule L in the following situations:

• Probate Property Expenses: Administration expenses for probate assets subject to creditor claims belong on Schedule J (Funeral Expenses and Expenses Incurred in Administering Property Subject to Claims).
• Reimbursed Casualty Losses: Losses fully covered and reimbursed by property insurance companies.
• Market Value Drops: Routine reductions in property or stock values caused by economic market fluctuations. Market price declines are **not** casualty losses under Section 2054.
• Expenses Claimed on Form 1041: Administrative or casualty expenses that the executor elects to deduct on the estate’s fiduciary income tax return (Form 1041) under Section 642(g).

5. When to File

Schedule L is an integrated supporting schedule attached to Form 706 and shares the exact same filing deadline as the primary return.

Review the primary submission timing deadlines:

• Nine-Month Due Date: Schedule L must be submitted attached to Form 706 within 9 months of the decedent’s date of death.
• Six-Month Extension: If the executor files Form 4768 to request an automatic 6-month filing extension, Schedule L is submitted when the extended Form 706 is filed (15 months from the date of death).
• Payment Timing Rule for Non-Probate Expenses: Under Section 2053(b), administrative expenses for non-probate property must be paid before the expiration of the statutory assessment period (generally within 3 years after Form 706 is filed).

6. Where and How to File

Schedule L is attached directly behind Schedule K in alphabetical schedule order on Form 706. It is filed by paper mail as part of the complete estate tax return package.

Mail the complete Form 706 package—including Schedule L, insurance claim statements, police reports, and trust fee billing statements—to the designated IRS submission center address listed in the official Form 706 instructions (typically the IRS Center in Kansas City, MO).

7. Step-by-Step Instructions to Fill the Form

Schedule L is divided into two distinct parts: Net Losses During Administration and Expenses for Property Not Subject to Claims. Review the section breakdown below.

Schedule L Section	Deduction Category	Required Information to Report
Top Section	Net Losses During Administration	Item number, description of damaged asset, cause/date of casualty or theft, gross loss, insurance reimbursement, and net loss.
Bottom Section	Expenses for Non-Probate Property	Item number, description of non-probate asset/trust, trustee fees, legal fees, appraisal costs, payment dates, and dollar amounts.

Top Section – Calculating Net Casualty and Theft Losses

Describe the specific damaged or stolen estate property. State the exact cause of loss (e.g., “Fire damage to rental property listed on Schedule A, Item 2”), the date of casualty, and the gross financial loss. Subtract any insurance payments, disaster grants, or third-party reimbursements received to compute the net deductible loss.

Bottom Section – Non-Probate Property Administration Expenses

List administrative costs paid to settle non-probate assets (such as a Revocable Living Trust reported on Schedule G):

• Trustee Commissions: Fees paid to corporate or individual trustees for settling trust assets after death.
• Legal and Accounting Fees: Professional fees paid to attorneys and CPAs for preparing trust accounts or distributing trust land to beneficiaries.
• Appraisal Charges: Valuation fees paid to appraise non-probate real estate or private business shares.

Total Line

Sum total net losses from the top section and total non-probate expenses from the bottom section. Carry this combined sum over to **Form 706, Part 5 (Recapitulation), Line 18**.

8. Required Documents/Information Needed Before Filling

The IRS requires comprehensive documentation to verify casualty losses and non-probate expenses claimed on Schedule L.

Ensure you have the following verification materials ready:

• Casualty & Theft Reports: Police reports, fire department reports, or official weather disaster records verifying the cause and date of loss.
• Insurance Settlement Statements: Claim statements from insurance companies showing total coverage payouts or formal coverage denial letters.
• Repair Invoices & Appraisals: Contractor repair estimates or “before and after” appraisal reports proving the exact reduction in property value.
• Trust Agreements & Invoices: Copies of governing revocable trust agreements, trustee fee schedules, and itemized legal/accounting bills.

9. Common Mistakes to Avoid

Deduction errors on Schedule L frequently trigger IRS estate tax audits. Avoid these common mistakes:

• Deducting Stock Market Price Declines: Claiming investment portfolio losses caused by general stock market downturns as “casualty losses.” Routine market drops are **not** casualty losses under Section 2054.
• Claiming Double Deductions (Section 642(g)): Deducting non-probate administrative expenses or casualty losses on both Form 706 Schedule L and the estate’s income tax return (Form 1041) without attaching the mandatory Section 642(g) waiver statement.
• Confusing Schedule J and Schedule L: Reporting trust administration fees for non-probate trusts on Schedule J instead of Schedule L. Schedule J is strictly for probate property subject to claims.
• Failing to Subtract Insurance Offsets: Deducting the full amount of a casualty loss without subtracting insurance reimbursements received by the estate.
• Missing the 3-Year Payment Deadline: Claiming estimated non-probate trust expenses that are not actually paid within the statutory 3-year assessment window under Section 2053(b).

10. Penalties for Non-Filing or Errors

Overstating casualty losses or claiming unallowable non-probate expenses on Schedule L carries severe statutory civil penalties under federal tax law.

Key penalty risks include:

• Disallowance of Claimed Deductions: The IRS will disallow unverified or double-deducted losses, increasing the taxable gross estate and generating an immediate estate tax deficiency bill.
• Accuracy-Related Penalty (IRC Section 6662): A 20% civil penalty applies to estate tax underpayments resulting from negligence or overstated deductions.
• Compounding Interest: Additional estate tax owed due to disallowed deductions incurs mandatory compounding interest from the original 9-month filing due date.

11. Related Forms or Schedules

Schedule L operates in direct combination with several core Form 706 schedules and income tax returns:

• Form 706: United States Estate (and Generation-Skipping Transfer) Tax Return.
• Form 706 (Schedule G): Transfers During Decedent’s Life (for revocable trusts).
• Form 706 (Schedule J): Funeral Expenses and Expenses Incurred in Administering Property Subject to Claims.
• Form 1041: U.S. Income Tax Return for Estates and Trusts (subject to Section 642(g) double deduction rules).
• Form 4684: Casualties and Thefts (for income tax reporting).

12. Frequently Asked Questions

IRS Form 706 Schedule L is the supporting schedule used by estate executors to deduct uncompensated casualty/theft losses incurred during estate settlement and administrative expenses for non-probate property.

2. What is the difference between Schedule J and Schedule L on Form 706?

Schedule J reports administration expenses for probate property *subject to claims*. Schedule L reports administration expenses for non-probate property *not subject to claims* (such as revocable trusts) plus casualty losses.

3. Are stock market drops deductible as losses on Schedule L?

No. Market price declines in stocks, bonds, or real estate are not casualty losses under Section 2054. Section 2054 applies strictly to sudden, unexpected physical damage or theft.

4. Can trustee fees for managing a Revocable Living Trust be deducted on Schedule L?

Yes. Trustee fees, legal costs, and accounting fees directly incurred in settling or distributing assets held in a Revocable Living Trust are deductible on Schedule L under Section 2053(b).

5. What is the double deduction rule under Section 642(g)?

Section 642(g) prohibits claiming the same administration expense or casualty loss as an estate tax deduction on Form 706 and an income tax deduction on Form 1041. The executor must execute a waiver choosing one tax return.

6. Must casualty losses be reduced by insurance payouts on Schedule L?

Yes. Only the net, uncompensated portion of a casualty or theft loss (total loss minus insurance proceeds received or expected) is deductible on Schedule L.

13. Conclusion

IRS Form 706 (Schedule L) is a vital schedule for capturing non-probate trust expenses and uncompensated estate property losses. By properly distinguishing between probate and non-probate costs and documenting casualty events, executors maximize allowable estate tax deductions.

To ensure full IRS compliance, gather police and insurance reports for casualty losses, retain itemized trustee and legal invoices for non-probate trusts, file Section 642(g) waivers to avoid double deductions, and carry total values over to Form 706.
