“Just write it off.”

This is a very common phrase heard by small business owners. And it makes sense. If you’re hosting clients, or driving to a meeting, you can write off most of those expenses. But that round of golf? No so fast.

You can certainly use company funds to pay for things like hosting golf, but the IRS does not permit those expenses to be deducted on your taxes. Small business deductions reduce the income you pay tax on. Common examples include employee wages, rent, software, insurance, and advertising. Some costs have limits. Others must be deducted over time.

The key is knowing which costs qualify, how much you can claim, and when you can claim them. Paying with a business card does not turn a personal purchase into a write-off.

This guide covers U.S. federal tax rules for 2026. State rules can differ.

How Small Business Deductions Work

The IRS generally requires a business expense to be ordinary and necessary. Ordinary means common in your line of work. Necessary means helpful and appropriate. It does not have to be essential to keeping the doors open. The IRS guide to starting a business explains this test.

A deduction reduces taxable income. A tax credit reduces the tax itself, subject to its own limits.

For example, assume a $1,000 expense is fully deductible and saves income tax at a 24% marginal rate. The income tax savings would be $240. You still spent $760 after that savings. This example ignores state tax, self-employment tax, and other deductions.

A write-off is not free money. Buy what helps the business earn more or work better.

Common Small Business Deductions

Here is a quick guide. Each deduction still needs a business purpose and records to support it.

Expense	Typical Federal Treatment	Key Limit
Wages, Rent And Software	Usually deductible	Business use; timing rules apply
Client Meals	Usually 50%	Qualifying business meal
Business Gifts	Up to $25	Per recipient per year
Business Mileage	72.5¢ per mile in 2026	Eligible miles; no double counting
Home Office	Simplified or actual costs	Space must qualify; income limits
Equipment	Immediate or over time	Eligibility and placed-in-service rules
Client Golf And Tickets	Generally 0%	Entertainment is nondeductible
Personal Costs	0% as business expenses	Separate from business spending

People You Pay

Common costs include employee wages, employer payroll taxes, contractor fees, and business-related accountant or lawyer fees. Eligible employee benefits and retirement contributions can qualify, too.

Pay must be reasonable for the work performed. A sole proprietor cannot deduct draws paid to themselves as wages. Owner pay follows different rules for partnerships and corporations.

Your Workplace And Daily Tools

Typical operating costs include:

• Rent for business space and business utilities.
• Software subscriptions, hosting, and routine website costs.
• Supplies, postage, and ordinary repairs.
• Business insurance, licenses, and permits.
• Advertising, bank fees, and payment processing fees.

Large improvements and some website development costs may need to be deducted over time. The IRS business-expense resource guide links to the rules by category.

Inventory And Products You Sell

Inventory costs commonly include goods, freight to bring them in, and certain production costs. Under the usual inventory method, these costs become cost of goods sold when the products sell.

Eligible small businesses can use alternative inventory methods. Timing depends on the method you properly adopt. Do not assume that paying a supplier creates an immediate deduction, or deduct inventory a second time as supplies. See the IRS inventory rules.

Business Travel

Airfare, lodging, and local transportation can qualify when you travel away from your tax home for business long enough to need sleep or rest. Your tax home is generally your main work area, not necessarily where your family lives.

Separate vacation costs from business costs. A spouse’s travel generally does not qualify unless the spouse is an employee, has a real business purpose, and meets the other requirements. The IRS business-travel rules explain the limits.

Education For Your Current Work

A course may qualify if it maintains or improves skills used in your current business. Education that meets minimum job requirements or qualifies you for a new trade generally does not qualify as a business deduction. See the IRS work-related education rules.

Interest And Owner Health Insurance

Interest on money used for the business may be deductible, subject to limits. Repaying loan principal is not an expense. The use of the borrowed money matters more than the account’s name.

Eligible self-employed owners may also deduct health insurance premiums on their individual returns. Earned-income limits and access to employer-subsidized coverage can restrict that deduction. It is not simply another Schedule C insurance expense. See the Schedule C instructions.

Deductions With Limits

Business Meals Are Usually 50% Deductible

A qualifying client meal or meal while traveling for business is generally 50% deductible. You or an employee must be present, and the cost cannot be lavish or extravagant under the circumstances. Record the business purpose and who attended.

A solo lunch during an ordinary workday is generally personal. Eating while answering emails does not change that. See the IRS business-meal guidance.

At a sporting event, food must be bought separately or separately stated at a proper price on the bill to qualify for the meal deduction. The tickets remain nondeductible. Some employee social events, such as a qualifying holiday party, can be fully deductible.

Starting in 2026, deductions are generally eliminated for meals furnished for the employer’s convenience and food provided through certain employer-operated eating facilities. Exceptions remain. Do not put every employee meal or office snack in one tax bucket. Check the 2026 employer meal rules.

Business Gifts Usually Have A $25 Limit

You can generally deduct up to $25 in business gifts per recipient per year. Giving one client a $100 gift does not create a $100 deduction.

Incidental costs such as shipping or engraving generally do not count toward the limit if they do not add substantial value. Employee gifts follow different rules. See IRS Publication 463.

A Home Office Must Meet Specific Tests

A self-employed owner’s space generally must be used regularly and exclusively for business. A desk that doubles as the family dinner table usually fails the exclusive-use test.

The space may qualify as your principal place of business, a place where you regularly meet clients, or a separate structure used for work. A home office used for administrative work can qualify if you have no other fixed location where you do substantial administrative work. Special rules apply to daycare and inventory storage. See the IRS home-office eligibility rules.

There are two calculation methods:

• Simplified method: $5 per qualifying square foot, up to 300 square feet. The maximum is $1,500 for a full year, subject to the income limit.
• Actual-expense method: Eligible costs include the business share of rent or qualifying ownership costs, utilities, insurance, repairs, and depreciation.

You cannot deduct mortgage principal. Income limits can restrict the deduction. Some disallowed actual expenses can carry forward; unused simplified deductions cannot. Depreciation can also affect taxes when you sell your home. IRS Publication 587 covers these details.

Vehicle Deductions Cover Business Use

The 2026 IRS business mileage rate is 72.5 cents per mile. At that rate, 5,000 qualifying business miles produce a $3,625 deduction before eligible parking and tolls.

You generally choose standard mileage or the business share of actual vehicle costs. The mileage rate replaces costs such as gas, repairs, insurance, and depreciation. Do not deduct those again. Business parking and tolls can be added.

Method choice has long-term consequences. For a car you own, you generally must choose standard mileage in its first business-use year to preserve that option. Leased cars have different switching rules. See the IRS vehicle deduction rules.

Your normal commute is personal. Travel from a qualifying principal home office to another work location in the same business may qualify. Keep a dated mileage log with destinations and business purposes, plus total annual mileage.

Mixed Bills Need A Business Percentage

If a phone bill is 70% business use, the business share is generally 70%. Use a reasonable method and keep support for the split. Apply the same care to internet service, vehicles, and other shared costs.

What You Usually Cannot Deduct

Common exclusions include:

• Personal groceries, vacations, gym memberships, and everyday clothing.
• Commuting to your regular workplace.
• Client golf outings, sports tickets, and most other entertainment.
• Country club and social club dues.
• Political contributions and most lobbying costs.
• Government fines and penalties for breaking the law, subject to narrow exceptions.
• Federal income taxes.
• Life insurance premiums when you or the business is a direct or indirect beneficiary.
• Owner draws, loan principal, and money merely set aside for future expenses.

A hobby does not get the same expense deductions as a business operated for profit. And a business loss does not automatically prove that an activity is a hobby.

Nondeductible does not mean unrecorded. If the company pays for client golf, record the payment and classify it as nondeductible entertainment. Personal purchases paid by the business also need proper entries, such as owner draws where appropriate. Leaving them out makes the books wrong.

DailyDime’s guide to debits and credits explains how payments flow through your accounts. For tax treatment, use the IRS expense guidance and travel and entertainment rules.

Other Tax Breaks Worth Reviewing

The 20% QBI Deduction

Eligible sole proprietors and owners of partnerships and S corporations may deduct up to 20% of qualified business income, or QBI. An LLC’s eligibility depends on how it is taxed. C corporations do not qualify.

QBI generally means eligible net business income, not revenue. Owner wages and partnership guaranteed payments generally do not count. Taxable-income limits apply, and higher-income owners can face wage, property, and service-business restrictions.

The deduction no longer has its former 2025 expiration date. In 2026, eligible individuals with at least $1,000 of aggregate QBI from businesses in which they materially participate can receive a $400 minimum deduction. Material participation has specific tax tests; occasional involvement is not enough.

This deduction reduces income tax, not self-employment tax. See the IRS QBI overview and 2026 estimated-tax guide.

Section 179 And Bonus Depreciation

Equipment normally has its cost spread over time through depreciation. These rules may let you deduct qualifying costs sooner:

• Section 179: The 2026 limit is $2.56 million. It starts shrinking when qualifying property placed in service exceeds $4.09 million. A business-income limit also applies.
• Bonus depreciation: Qualifying property acquired and placed in service after January 19, 2025, generally qualifies for 100% bonus depreciation. Acquisition and contract rules matter.

Section 179 generally cannot create a business tax loss. Bonus depreciation can, although other loss limits may delay the benefit. Cars, SUVs, and mixed-use property have extra restrictions. Land is not depreciable.

Equipment must be ready and available for business use. Ordering it in December is not enough. See IRS Publication 946.

Startup And Organizational Costs

You can generally deduct up to $5,000 of eligible startup costs when your active business begins. The immediate deduction falls dollar for dollar once those costs exceed $50,000. It reaches zero at $55,000.

Remaining eligible costs are generally deducted over 180 months, beginning in the month the business starts. Qualifying organizational costs may receive a separate $5,000 deduction with their own $50,000 phaseout. Equipment and inventory follow their own rules. See the IRS startup-cost guidance.

Retirement Contributions

A SEP IRA, one-participant 401(k), or SIMPLE IRA can help eligible owners save while reducing current taxable income through deductible contributions. Roth contributions generally do not provide a current deduction.

Limits depend on the plan, earnings, age, and other plan participation. A one-participant 401(k) generally covers an owner with no employees other than a spouse. Hiring eligible workers changes the rules.

Setup, election, and funding deadlines differ. Review the IRS retirement-plan options before year-end.

Research Deductions And The R&D Credit

Domestic research and experimental costs generally qualify for a current deduction under Section 174A for tax years beginning after 2024. Foreign research costs generally remain subject to 15-year amortization. See the IRS research-expense guidance.

The research credit is a separate benefit with narrower tests. Qualifying work generally uses a process of experimentation to resolve technical uncertainty about a product, process, or software. Routine updates, market research, and ordinary product development do not automatically qualify.

For the payroll-tax election, a qualified small business generally must have less than $5 million in current-year gross receipts and no gross receipts before the five-tax-year period ending with that year. Related-business rules can affect eligibility. See the Form 6765 instructions.

Eligible businesses can elect to apply up to $500,000 of their available research credit against the employer share of Social Security and Medicare taxes, subject to the applicable limits. This is not an automatic $500,000 payment. Elections are limited to five tax years, and unused amounts may carry forward.

Keep project, payroll, and cost records. The deduction and credit also require adjustments to prevent double benefits. The IRS payroll research-credit guide explains the filing process.

Paying Now Does Not Always Mean Deducting Now

Cash-method businesses generally deduct eligible operating costs when paid. Accrual-method businesses generally deduct them when the tax rules for an incurred expense are met. Prepayments, inventory, assets, and related-party transactions have special rules.

A monthly software bill is often a current expense. A laptop is equipment that may qualify for an immediate write-off. A major remodel may need to be depreciated, though certain improvements qualify for faster deductions.

The price alone does not settle the question. Many businesses without an applicable financial statement can elect the de minimis safe harbor for qualifying items costing up to $2,500 per item or invoice, if its requirements are met. The Schedule C instructions explain this option.

What Records Should You Keep?

Save the date, amount, vendor, and business purpose. Keep invoices and proof of payment. For meals and gifts, document the recipient or attendees and business relationship. For vehicles, keep mileage records. For equipment, keep purchase and placed-in-service dates.

Travel, meal, gift, and vehicle expenses have stricter proof rules. Documentary evidence is generally required for lodging and expenses of $75 or more, with exceptions. Smaller costs still need support. A bank statement alone may show a payment without proving its business purpose.

Keep ordinary tax records generally for at least three years, but longer periods apply in some cases. Keep asset records through the relevant period after disposal. Employment-tax records generally need to be kept at least four years after the tax is due or paid, whichever is later. See the IRS recordkeeping rules.

A Simple Monthly Routine

1. Use a separate business bank account and card.
2. Review transactions weekly. Identify operating costs, limited deductions, assets, and personal charges.
3. Save receipts and add the business purpose while you remember it.
4. Log business mileage as you go.
5. Reconcile the accounts each month, including nondeductible payments.
6. Before year-end, review equipment needs, retirement deadlines, and tax elections with your tax preparer.

Good records capture the deductions you earned. Extra spending creates extra bills.

Frequently Asked Questions

What Are Small Business Deductions?

They are qualifying costs and allowances that reduce taxable income. Some reduce business profit. Others, such as QBI, are claimed separately on an owner’s return. Limits and timing rules apply.

Does An LLC Get Better Deductions?

Not by itself. Federal tax treatment depends on whether the LLC is taxed as a sole proprietorship, partnership, S corporation, or C corporation. An LLC does not turn personal costs into business expenses.

Can I Deduct Coffee, A Gym, Or New Clothes?

A qualifying client coffee meeting may fall under the 50% meal rule. Your daily coffee, personal gym membership, and clothing suitable for everyday wear are generally personal. Required protective gear or work uniforms unsuitable for everyday use may qualify.

Can I Deduct Golf With A Client?

The golf outing is generally nondeductible entertainment, even if you discuss business. A separately purchased qualifying business meal may still be 50% deductible. Country club dues generally are not deductible.

Should I Buy Equipment In December?

Only if the business needs it and the numbers make sense. An immediate deduction generally requires the equipment to be placed in service that year. Compare the tax savings with the cash leaving your account.

Do I Need To Itemize To Claim Business Expenses?

Generally, no. A sole proprietor can claim eligible Schedule C expenses while taking the standard deduction on the individual return. Business deductions and personal itemized deductions are different.
