THE SHORT ANSWER
A police report proves neither a federal deduction nor its amount
Classify the gold as personal-use, investment, business or inventory property; document adjusted basis, event, discovery date, reimbursements and any disaster declaration. The IRS announced a 2026 expansion for certain state-declared-disaster casualty losses. The 2025 Publication 547 and Form 4684 instructions do not yet provide a complete 2026 filing workflow, so use the final incident-year form.
2026 SOURCE CONFLICT
The new IRS update changes scope; the current detailed publication still describes 2025 rules
Publication 547 (2025) generally limits net personal-use casualty and theft deductions to federally declared disasters, with stated exceptions. On July 27, 2026, the IRS said the deduction was made permanent and expanded beginning in 2026 to include certain losses from state-declared disasters. That update does not turn an ordinary non-disaster theft into an automatic deduction. Preserve the declaration and wait for or consult the 2026 instructions.

REIMBURSEMENT FIRST
A reasonable prospect of recovery can postpone the loss year
Publication 547 and Form 4684 instructions say a loss is not sustained while a reimbursement claim has a reasonable prospect of recovery. File a timely insurance claim when coverage exists, preserve insurer and carrier decisions, and separate amounts paid, expected, denied or still disputed. A later reimbursement for a previously deducted loss can have additional tax consequences.
GAIN POSSIBILITY
Replacement-value insurance can create a gain even though property was stolen
Compare insurance and other reimbursement with adjusted basis, not merely with current retail replacement price. Publication 547 describes casualty and theft gains and a possible election to postpone gain when qualifying replacement property is acquired within the applicable period. Keep the settlement allocation, replacement purchase, dates and basis computation.

FAQ
Gold theft tax questions
Is stolen personal gold deductible in 2026?
Do not assume it is. The IRS announced that beginning in 2026 certain personal casualty losses tied to state-declared disasters join federal-disaster losses, but ordinary burglary is not automatically covered. Property use, event, declaration, gains and reimbursement matter.
When is a theft loss sustained?
Publication 547 generally uses the year the theft is discovered, but a claim with a reasonable prospect of reimbursement can delay the loss until the reimbursement outcome is reasonably certain.
What if insurance pays more than basis?
A reimbursement exceeding adjusted basis can create a casualty or theft gain. Publication 547 describes possible gain postponement when qualifying replacement property is acquired within the applicable replacement period.
Which Form 4684 section applies?
Current instructions use Section A for personal-use property and Section B for business or income-producing property. Use the form for the incident year because 2026 law changes may alter instructions.
