But as of 2018 tax payers could claim up to $2500 per invoice or item for taxpayers without applicable financial statements. More than that, you'll need to provide an applicable financial statement (AFS) if questioned/audited on the claim.
The $2,500 per invoice was increased (from $500) for tax years beginning on or after January 1, 2016 and no AFS is necessary.
