As 2025 winds down, now is the time for small business owners, S‑Corps, LLCs, and 1099 contractors to take action. These 11 deductions offer real opportunities — if you claim them before December 31.
Depreciation & Equipment Expensing
If your business bought equipment, furniture, software, or other qualified assets this year — from computers to office furniture — you may be eligible to immediately deduct the full cost under the current rules for expensing or accelerated depreciation. This reduces your taxable income now rather than spreading the deduction over multiple years. TurboTax+2Wikipedia+2
Prepaid or Accelerated Expenses
For cash‑basis businesses, you can prepay certain expenses before year-end — such as rent, insurance, or vendor services — and deduct them in 2025. This offers flexibility: if you expect higher income next year, prepaying now can reduce this year’s tax burden. Bradford Tax Institute+1
Home Office Allocation (When Applicable)
If you operate partially or fully from home and maintain a dedicated, exclusive workspace, you may deduct a portion of home‑related costs (utilities, rent or mortgage interest, insurance) proportionate to the business‑use square footage. This remains one of the most under‑utilized deductions among small business owners. NerdWallet+1
Utilities, Internet, and Business Facility Expenses
For businesses operating from a separate facility — or even a dedicated home office — monthly expenses such as utilities, phone, internet, repairs, maintenance, and rent are valid deductions. This also applies to storage, rental space, or coworking memberships. NerdWallet+1
Office Supplies, Software, Subscriptions & Tools
All routine business supplies — from office stationery to software subscriptions, cloud services, or tools necessary for your work — qualify as deductible expenses. These often slip through the cracks because owners underestimate how many small purchases add up. Brex+1
Advertising, Marketing, and Branding Costs
Whether you run digital ads, maintain a website, order flyers, or invest in branding and design — those expenses are fully deductible. End‑of‑year marketing pushes can lower your taxable income while promoting growth. NerdWallet+1
Contract Labor and Independent Contractors
Payments to freelancers, subcontractors, or independent contractors (as long as you issue the proper 1099 forms where required) count as deductible business expenses. If you expect to hire more or pay contractors before year-end, make sure to track those payments carefully. NerdWallet+1
Business Insurance, Licenses, and Professional Fees
Premiums for business insurance (liability, property, business auto), licenses, permits, and fees paid to accountants or legal professionals are deductible. If your business renewed such policies or paid consulting fees this year — don’t overlook them. NerdWallet+1
Retirement Plan Contributions and Employee Benefits (If Applicable)
If your business offers a retirement plan (or contributes as a self‑employed individual), those contributions can reduce taxable income. Offering consistent benefits or setting up eligible accounts before year-end can yield significant savings. NerdWallet+1
Cost of Goods Sold (COGS) & Inventory Adjustments
For businesses that manufacture or resell products, the cost of raw materials, direct labor, packaging, and inventory handling are deductible. Reviewing your inventory and COGS before year-end ensures you properly account for your costs and optimize deductions. NerdWallet+2CBIA+2
Business Meals and Client Entertainment (With Proper Documentation)
When business meals or entertainment are directly related to business operations — for example, meals with clients, suppliers, or team meetings — a portion of the expense may qualify for deduction (subject to current IRS rules). Ensure receipts and legitimate business purpose are documented. NerdWallet+1
Businesses that fail to review these deductions often miss out on substantial savings. According to recent analyses, as many as 90% of small business owners under‑utilize one or more legitimate write‑offs — meaning they pay more tax than necessary. Online CPA Tax Services | My CPA Coach+1
