Bitcoin IRS Reporting Basics

16 min readarticleIncludes quiz · 2 questions

Bitcoin is treated as property by the IRS, not currency. This means every transaction—buying, selling, trading, or spending—creates a taxable event that must be reported. Understanding these requirements is crucial for compliance and avoiding penalties.

Key IRS classifications:

  • •Property: Bitcoin is treated as capital assets like stocks
  • •Virtual Currency: Defined by FinCEN as a medium of exchange
  • •Taxable Events: Every disposal creates a tax liability
  • •Basis Tracking: Must track acquisition cost for every unit
  • •Record Keeping: 7-year requirement for all transaction records

Required reporting forms:

  • •Form 8949: Sales and other dispositions of capital assets
  • •Schedule D: Capital gains and losses summary
  • •Form 1040: Report net gains/losses on main return
  • •Form 8938: Foreign account reporting (if applicable)
  • •FBAR: Foreign bank account reporting (if using foreign exchanges)

Record keeping requirements:

  • •Transaction dates: When acquired and disposed
  • •Fair market value: USD value at transaction times
  • •Transaction purpose: Why you acquired/disposed
  • •Counterparty information: Who you transacted with
  • •Exchange records: Screen shots and statements
