In 2026, the "limit" on miscellaneous expenses depends on whether you are referring to corporate reimbursement or IRS tax deductions. For corporate travel, many companies use a per diem model where "incidentals" (tips, laundry, small fees) are capped at $5 to $10 per day without requiring individual receipts. For tax purposes, the IRS generally defines miscellaneous business expenses as those that are "ordinary and necessary" for your profession. However, since the tax reforms of the late 2010s and early 2020s, most W-2 employees can no longer deduct unreimbursed miscellaneous expenses. For self-employed individuals in 2026, there is no hard "dollar limit," but any single expense over $75 usually requires a formal receipt to be defensible in an audit. If "miscellaneous" exceeds 5-10% of your total business revenue, it often triggers a "red flag" for manual review, so it is always better to categorize expenses specifically (e.g., "Professional Dues" or "Software Subscriptions") rather than using a general "Miscellaneous" bucket.
