What Are the Main LLC Business Deductions?

The foundation of LLC write-offs rests on Internal Revenue Code Section 162, which allows deduction of “all ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.” For Evanston LLCs operating in 2026, this broad provision creates multiple opportunities to reduce taxable income. Understanding which expenses qualify is critical for maximizing your tax savings.

Ordinary means the expense is common and accepted in your industry. Necessary means it helps you conduct business. An expense doesn’t need to be essential to qualify—it simply needs to have a legitimate business purpose. Evanston LLC owners frequently miss deductions because they assume expenses must be unusual or absolutely critical to qualify.

Common Deductible Business Expenses for 2026

• Salary and Wages: Compensation paid to employees is fully deductible. The IRS requires reasonable compensation for S Corp owners, but LLC managers have more flexibility.
• Rent and Facility Costs: Monthly rent for office or warehouse space is deductible. Shared office space costs, coworking memberships, and parking are also eligible.
• Utilities and Internet: Electric, water, gas, phone, and high-speed internet serving your business location qualify as deductions.
• Office Supplies and Equipment: Items under $2,500 are immediately deductible. Furniture, computers, and machinery qualify based on asset classification.
• Insurance Premiums: Business liability, property, workers’ compensation, and professional liability insurance are fully deductible in 2026.
• Professional Services: Accounting, legal, consulting, and marketing services paid to independent contractors are deductible.
• Software and Subscriptions: Business software, SaaS tools, accounting platforms, and industry-specific subscriptions count as 2026 write-offs.

A critical but often overlooked category involves meals and entertainment. Under 2026 tax rules, 50% of meal expenses are deductible if they’re directly related to business. However, entertainment costs (sporting events, concerts, etc.) are generally not deductible in 2026, unlike prior years when 50% was allowed.

Expenses You Cannot Deduct as LLC Write-Offs

Not every business expenditure qualifies as a write-off. The IRS strictly disallows certain categories to prevent abuse. Evanston LLC owners should particularly avoid claiming personal expenses, non-business gifts exceeding $25 annually per recipient, or penalties and fines. Charitable contributions have special rules in 2026—the new OBBBA charitable deduction for non-itemizers allows up to $300 deduction for married couples ($150 for singles), but other charitable giving follows standard itemization rules.

How Do Home Office Deductions Work for Evanston LLCs?

Home office deductions are among the most valuable yet underutilized write-offs available to Evanston LLCs. The IRS allows two calculation methods, each with distinct advantages depending on your situation. The simplified method offers ease of computation, while the actual expense method maximizes deductions for owners with larger dedicated office spaces or expensive properties.

The Simplified Method: Fast and Easy

The simplified method requires no depreciation calculations and applies the same $5-per-square-foot rate nationwide, updated annually by the IRS. For 2026, a 200-square-foot home office yields a $1,000 annual deduction. This method works best for LLC owners who lack detailed expense records or prefer simplified compliance. You cannot have used the actual expense method in prior years to claim depreciation on your home if you switch to simplified.

The Actual Expense Method: Maximizes 2026 Write-Offs

The actual expense method requires calculating your home’s business-use percentage and deducting that percentage of relevant expenses. If you use 300 square feet of a 2,000-square-foot home for business, your deductible percentage is 15%. Apply this to mortgage interest (or rent), property tax, utilities, home insurance, repairs, and depreciation. For example, a $2,400 annual utility bill becomes a $360 deduction (15%). Over time, the actual method typically yields higher deductions for Evanston LLC owners with dedicated office space.

Method	2026 Formula	Best For
Simplified	$5/sq ft × office size (max 300 sq ft = $1,500)	Owners preferring ease and avoiding depreciation tracking
Actual Expense	% business use × (mortgage interest + utilities + insurance + depreciation + repairs)	Owners with larger dedicated offices or high home expenses

One critical limitation: your home must be used regularly and exclusively for business. A guest bedroom used occasionally for customer meetings doesn’t qualify. Additionally, when you sell your home, the portion attributable to depreciation is subject to recapture tax. Many Evanston LLC owners use this strategy strategically, claiming deductions for high-expense years and reconsidering in lower-income years to minimize recapture exposure.

What Vehicle and Travel Deductions Can You Claim?

Vehicle and travel expenses represent significant write-off opportunities for Evanston LLCs, but the rules demand careful documentation and clear business purpose. The IRS disallows commuting from home to your regular workplace, but trips to client sites, supplier visits, and industry conferences qualify. For 2026, the standard mileage rate is $0.67 per business mile—ensure you’re tracking this rate, which changes annually.

Standard Mileage Rate vs. Actual Expense Method

The standard mileage method simplifies calculation: multiply 2026 business miles by $0.67 to get your deduction. This method includes fuel, maintenance, depreciation, and insurance. The actual expense method requires tracking all vehicle costs and calculating the business-use percentage. If you drive your vehicle 20,000 miles annually with 12,000 being business miles (60%), you can deduct 60% of gas, insurance, registration, repairs, and depreciation. High-mileage Evanston LLC owners often benefit from the actual expense method; lower-mileage users typically prefer the standard rate.

Travel Expenses and the New 2026 Car Loan Interest Deduction

OBBBA introduced a new temporary deduction for car loan interest (2025-2028 tax years). For qualifying new vehicles purchased in 2026, you may deduct up to $2,500 in car loan interest annually. The vehicle must meet U.S. final assembly requirements and be used for business. This is separate from standard mileage deductions and applies to personal-use vehicle loans. For business-only vehicles, standard depreciation and mileage rules apply instead.

How Does Depreciation Maximize LLC Write-Offs?

Depreciation represents one of the most powerful yet complex deduction categories available to Evanston LLC owners. Unlike expense deductions that reduce income dollar-for-dollar in the year incurred, depreciation allows you to deduct the cost of business assets over multiple years—but recent tax law changes accelerated these timelines dramatically. Understanding OBBBA’s depreciation provisions for 2026 can defer thousands in tax liability.

Bonus Depreciation: The Game-Changer for 2026

OBBBA enhanced bonus depreciation for 2026. Generally, qualifying business property placed in service during 2026 can claim 100% bonus depreciation, allowing immediate deduction of the entire cost rather than spreading it over the asset’s useful life. This applies to machinery, equipment, vehicles, and certain real property improvements. An Evanston LLC purchasing $50,000 in equipment in 2026 can deduct the full amount immediately, not over 5-7 years.

Section 179 Expensing: Additional Deduction Flexibility

Section 179 allows Evanston LLCs to deduct up to $1.16 million of equipment purchases in 2026 (indexed annually for inflation). Unlike bonus depreciation, Section 179 has income thresholds and phase-out rules, but it offers flexibility for specific business property. Equipment, machinery, vehicles, and computer systems commonly qualify. Real property improvements, land, and inventory typically don’t qualify.

How Much Can You Deduct for Retirement Contributions?

Retirement contributions represent the highest-value deductions available to Evanston LLC owners because they reduce current taxable income while building future security. Unlike most business deductions that simply reduce tax liability, retirement deductions also grow tax-deferred, compounding your savings over decades. The 2026 limits are substantially higher than personal IRA contributions, providing significant tax deferral opportunities.

Solo 401(k): Maximum Deduction Strategy

A Solo 401(k) allows an Evanston LLC owner with no employees (except a spouse) to contribute up to $24,500 as an employee deferral in 2026, plus up to 20% of net self-employment income as an employer contribution. If your LLC generates $100,000 in net profit, you could contribute approximately $24,500 + $16,000 = $40,500 to a Solo 401(k), reducing taxable income by that amount. Solo 401(k)s also permit loans against your balance, providing liquidity if needed.

For owners age 50 or older, the catch-up contribution adds $8,000 to the employee deferral, bringing the total employee contribution to $32,500 for 2026. An additional higher catch-up applies for ages 60-63, allowing $11,250 instead of $8,000. These age-based provisions enable older LLC owners to accelerate retirement savings while claiming valuable deductions.

SEP-IRA: Simplest Retirement Deduction

A Simplified Employee Pension (SEP) IRA allows Evanston LLC owners to contribute up to 20% of net self-employment income for 2026, with a maximum of $69,000 annually. SEP-IRAs require minimal paperwork and no ongoing administration costs. If your LLC earns $200,000 in net profit, you could contribute approximately $40,000 to a SEP-IRA. Unlike Solo 401(k)s, SEP-IRAs don’t permit loans but offer simpler ongoing compliance and lower administrative burden.

What New Deductions Did OBBBA Introduce for 2026?

The One Big Beautiful Bill Act created new planning opportunities for Evanston LLC owners, though implementation challenges emerged during the 2026 tax filing season. Some new deductions faced reconciliation issues with employer-reported information. Understanding which OBBBA changes directly apply to your LLC and which create compliance risks is critical for maximizing legitimate write-offs while minimizing audit exposure.

Tip Income Deduction (Service Industry LLCs)

Service businesses including restaurants, salons, and hospitality operations can deduct 15% of reported tip income as a business expense, effective June 12, 2026. If your Evanston LLC reports $50,000 in tips annually, you can deduct $7,500 as a business expense, reducing your tax liability. This provision required final IRS regulations issued April 10, 2026, and implementation challenges emerged with return reconciliations.

Charitable Deduction for Non-Itemizers

Under OBBBA, married couples can deduct up to $300 in charitable contributions in 2026 without itemizing deductions; single filers can deduct up to $150. This benefits Evanston LLC owners who prefer standard deductions but want charitable deductions. Many taxpayers overlooked this benefit due to the relatively low income phase-out threshold and rapid phase-out rate implemented under the new law.

 

 

Uncle Kam in Action: Illinois LLC Tax Strategy

The Scenario: Marcus, an Evanston-based LLC owner, runs a digital marketing agency with $180,000 in annual revenue and operates from his home. He wasn’t consistently tracking expenses and missed several write-off opportunities in prior years.

The Challenge: Marcus reported nearly $150,000 in taxable income despite significant business expenses. His home office, vehicle costs, and retirement savings weren’t properly deducted, resulting in an estimated federal tax bill of $42,000 for the year. He also paid Illinois state income tax on inflated income figures. State LLC franchise tax considerations weren’t optimized, and he wasn’t capturing all available depreciation benefits.

Uncle Kam’s Solution: Our tax strategists implemented a comprehensive write-off strategy for Marcus’s 2026 return. We documented his home office using the actual expense method (300 sq ft of a 1,800 sq ft home = 16.7% business use), capturing $4,200 in utilities, insurance, and mortgage interest deductions. We tracked his vehicle mileage throughout the year, documenting 14,000 business miles at the 2026 standard rate of $0.67/mile, generating $9,380 in vehicle deductions.

We established a Solo 401(k) for Marcus, allowing him to contribute $24,500 in employee deferrals plus approximately $20,000 in employer contributions (20% of adjusted net profit), reducing his taxable income by $44,500. We also documented all software subscriptions ($3,600), professional services ($5,200), and office supplies ($1,800) that Marcus had been tracking informally. These optimizations reduced his taxable income from $150,000 to approximately $85,000.

The Results: By implementing comprehensive deduction strategies, Marcus reduced his estimated federal tax liability from $42,000 to approximately $19,000—a savings of $23,000 in the first year. His Illinois state income tax was similarly reduced. After paying Uncle Kam’s tax strategy fee of $2,500, Marcus achieved a net tax savings of $20,500. Additionally, his Solo 401(k) accumulated $44,500 in retirement assets that year, providing both immediate tax savings and future financial security. Marcus now maintains systematic expense tracking and quarterly tax planning reviews, ensuring he captures all available write-offs annually.

This case illustrates why Evanston LLC owners should work with entity structuring specialists to optimize deductions and state tax positions strategically.

Next Steps

1. Audit Your Current Deductions: Review prior-year returns to identify missed write-offs. Document business purposes for all expenses, especially vehicle, meals, and entertainment costs. Evanston LLC owners often discover $5,000-$15,000 in previously unclaimed deductions when auditing prior years.
2. Establish Retirement Plans: If you haven’t created a Solo 401(k) or SEP-IRA, consult a tax advisory professional immediately to evaluate which structure maximizes 2026 deductions for your specific income level and business structure.
3. Track Mileage Systematically: Begin tracking business mileage using a mileage app or notebook. The IRS requires contemporaneous records; retroactive estimates face higher audit risk. Document trip purpose, date, and mileage immediately after each business trip.
4. Consult on Entity Structure: Evaluate whether your current LLC structure optimizes write-offs. Consider consulting with Evanston tax preparation specialists about S Corp elections or multi-entity strategies that may increase deductible retirement contributions or reduce self-employment taxes.

Frequently Asked Questions

Can Evanston LLCs Deduct Home Office If They Also Rent Commercial Space?

Generally, no. The IRS disallows home office deductions if you maintain a dedicated commercial workspace for the same business. However, if you rent commercial space for client meetings but conduct administrative work exclusively from home, you may qualify for home office deductions. The key is exclusive and regular use for distinct business functions. Consult business owner tax guides for your specific situation.

What’s the IRS Definition of ‘Ordinary and Necessary’ for 2026?

Ordinary means the expense is common in your industry; necessary means it helps generate income. An expense doesn’t need to be essential or required by law. The IRS examines whether reasonable business owners in similar circumstances would incur the same expense. The standard is factual, not absolute—what’s ordinary for one business may not be for another.

How Does the $2,000 1099-NEC Threshold Affect Evanston LLC Write-Offs?

The 2026 federal reporting threshold for 1099-NEC and 1099-MISC payments raised to $2,000 (from $600). This means you must issue 1099-NEC only if you pay any single contractor $2,000 or more annually. However, payments below $2,000 are still business expenses and remain fully deductible. Illinois follows its own thresholds for state reporting. This change doesn’t affect the deductibility of contractor payments—only their reporting requirements.

Can I Deduct Losses From a Failed Side Business Within My LLC?

If the side business is within your LLC’s operations, yes, you can deduct actual losses. However, the IRS scrutinizes hobby losses—activities engaged in primarily for personal enjoyment rather than profit. If you consistently report losses, the IRS may reclassify the activity as a hobby, disallowing losses. The IRS applies a “presumption of profit” if you’re profitable in 3 of 5 years. Document your business plan and profit motive.

What Records Should I Keep for LLC Write-Offs to Survive an Audit?

Keep receipts, invoices, canceled checks, and credit card statements for all deducted expenses. For vehicle deductions, maintain a mileage log (contemporaneous, not retroactive). For home office deductions, keep home mortgage statements and property tax records. The IRS generally accepts business accounting records if they’re systematic and show business purpose. Digital records (photos of receipts, cloud-stored documents) are acceptable if originals are unavailable. Maintain records for at least three years; more is better for high-value deductions.

Does OBBBA’s Bonus Depreciation Apply to Used Equipment, or Only New?

For 2026, OBBBA’s enhanced bonus depreciation (generally 100%) applies primarily to new property, though some used property qualifies if you’re the original purchaser and certain other conditions are met. Used business equipment purchased from third parties may qualify for Section 179 expensing instead, allowing up to $1.16 million in deductions. Consult a tax specialist to determine if your specific equipment qualifies for bonus depreciation or requires alternative depreciation strategies.
