Quick Answer: ✅ Yes — Filing cabinets are fully deductible as office furniture or supplies when used for business document storage.

The Short Answer

A filing cabinet used to store business documents, client files, tax records, or other work materials is a straightforward business deduction. Most filing cabinets cost well under $2,500 and can be expensed immediately in the year you buy them.

IRS Rules for Deducting a Filing Cabinet

Filing cabinets are classified as office furniture under IRS Publication 946 — 7-year MACRS property. But since most cabinets cost a few hundred dollars, you'll typically use the de minimis safe harbor (IRS Reg. §1.263(a)-1(f)) to expense them immediately.

The IRS requires that the filing cabinet be used for a business purpose — storing client contracts, invoices, tax documents, employee records, etc. If you keep personal files in it too, allocate the cost based on business vs. personal use.

For home offices, the filing cabinet is deductible as part of your home office setup, provided you meet the exclusive and regular use test under Publication 587.

How Much Can You Deduct?

Cabinet Cost	Method	Deduction
-------------	--------	-----------
Under $2,500	De minimis safe harbor	100% immediately
Over $2,500 (fireproof/specialty)	Section 179 or MACRS	100% (179) or over 7 years
Mixed personal/business use	Any method	Business-use % only

Fireproof filing cabinets and high-security document storage units can cost more than $2,500 — in those cases, Section 179 lets you still deduct the full amount in year one.

How to Categorize in QuickBooks

QBO Category: Office Supplies (if under $2,500) or Furniture & Fixtures (if capitalizing)
Schedule C Line: Line 22 (Supplies) if expensing; Line 13 (Depreciation) if capitalizing
Tip: Most filing cabinets are under $500 — just expense them as Office Supplies and keep it simple.

Common Mistakes to Avoid

Over-complicating depreciation on cheap cabinets. A $150 filing cabinet doesn't need a depreciation schedule. Expense it under de minimis and move on.
Forgetting to deduct organizational supplies. Hanging file folders, labels, and drawer organizers that go with the cabinet are deductible too.
Not documenting business use in a home office. If audited, you'll need to show the cabinet stores business documents in a qualifying workspace.

Record-Keeping Requirements

Keep the purchase receipt with date, vendor, and amount. If the cabinet is in a home office, maintain your home office documentation. For specialty cabinets being depreciated, keep a fixed asset record. Retain records for at least 3 years from filing.
