HB 5115

AN ACT ESTABLISHING A PERSONAL INCOME TAX DEDUCTION
FOR CERTAIN LOSSES INCURRED AS A RESULT OF
CRYPTOCURRENCY INVESTMENT FRAUD OR WIRE FRAUD.

SUMMARY
This bill creates a personal income tax deduction for the amount of a
theft loss from cryptocurrency investment fraud or wire fraud that is
deductible for federal income tax purposes.
Federal law allows an income tax deduction for certain losses
sustained during a taxable year that are uncompensated, such as by
insurance. Specifically, for individuals with losses that are not
connected with a trade or business, it allows a deduction for:
1. losses incurred in a transaction entered into for profit (26 U.S.C.
§ 165(c)(2)) and
2. certain other losses not connected to a transaction entered into for
profit that are referred to as personal casualty losses (26 U.S.C. §§
165(c)(3) & (h)(3)(B)).
These two types of losses include losses from theft. By law, “theft”
includes larceny, embezzlement, and robbery. The amount of a loss is
generally the fair market value of the property when it was stolen (26
C.F.R. §§ 1.165-7 & 1.165-8).
There are several requirements to sustain a theft loss claim.
Generally, to do so, a taxpayer must establish that the loss was from an
illegal taking of property done with criminal intent that was illegal
under the law of the jurisdiction in which it occurred (Internal Revenue
Service Revenue Ruling 2009-9).
