Estimated annual tax savings for a business earning $150K–$300K net profit
Strategy 1: Claim the QBI Deduction (Now 23%)
What it is and who qualifies
The Qualified Business Income (QBI) deduction under Section 199A lets pass-through business owners - sole proprietors, S-Corp shareholders, LLC members, and partners - deduct a percentage of their net business income from their personal tax return. Before the OBBBA, the rate was 20% and was set to expire after 2025. Now it's permanent and raised to 23% starting in 2026. If your consulting firm earns $120,000 in net profit, you can deduct $27,600 before your income even hits the tax brackets - reducing your federal tax bill by $6,000–$9,000 depending on your bracket. For 2026, the phase-out begins at $75,000 for single filers and $150,000 for joint filers. Above those thresholds, deduction limits apply for service businesses (law, consulting, finance, health). A $400 minimum deduction now applies if you have at least $1,000 in qualified business income - so even small businesses benefit.
Rate: 23% of qualified business income (up from 20% in 2025)
Applies to: sole proprietors, S-Corps, LLCs, partnerships
Full deduction below $75K (single) / $150K (joint) phase-in threshold
New $400 minimum deduction for businesses with $1,000+ in QBI
Service businesses (law, consulting, finance) face phase-out above income limits
Strategy 2: Write Off Equipment Immediately with Section 179 and Bonus Depreciation
Deduct the full cost of equipment in year one
Normally, equipment is depreciated over 5–7 years. Section 179 lets you deduct the entire purchase price in the year you place it in service. For 2026, the maximum deduction is $2,560,000 - more than double the pre-OBBBA limit of $1,250,000. The phase-out begins at $4,090,000 in total qualifying purchases and disappears at $6,650,000. On top of that, 100% bonus depreciation is now permanent (restored by OBBBA for property placed in service after January 19, 2025). This means after applying Section 179, any remaining equipment basis can be expensed at 100% in year one. Qualifying property includes machinery, computers, office furniture, software, and vehicles over 6,000 lbs GVWR. The IRS requires Section 179 first, then bonus depreciation on the remaining balance. One important constraint: Section 179 cannot exceed your business taxable income for the year (though any excess carries forward). Bonus depreciation has no such cap and can even create a loss.
Section 179 limit 2026: $2,560,000 (phase-out starts at $4,090,000)
100% bonus depreciation: permanent, applies to new and used equipment
Heavy vehicles (6,000+ lbs GVWR): up to $31,300 via Section 179 + full 100% bonus on remaining basis
Light vehicles (under 6,000 lbs): $12,200 Section 179 cap + $8,000 bonus = $20,200 max first year
Software, computers, office furniture all qualify
Section 179 vs. Bonus Depreciation: Quick Comparison 2026
| Feature | Section 179 | Bonus Depreciation |
|---|---|---|
| Max deduction | $2,560,000 | No dollar cap |
| Can create a loss? | No (income limit) | Yes |
| New vs. used property | Both | Both |
| Elective? | Yes - you choose amount | Applied automatically (unless opt-out) |
| Best use | Targeted deduction to hit a specific income level | Large purchases exceeding Section 179 limits |
The IRS requires you to apply Section 179 first, then bonus depreciation. Work with a CPA or tax tool to optimize the order based on your income and carry-forward position.
Strategy 3: Elect S-Corp Status to Cut Self-Employment Tax
How S-Corp election reduces your tax bill
Self-employment tax is 15.3% on the first $184,500 of net income in 2026 (12.4% Social Security + 2.9% Medicare) - and you pay both the employee and employer halves. That's on top of income tax. If your business earns $150,000 in net profit as a sole proprietor, your SE tax alone is around $21,000. An S-Corp election changes the math. Instead of paying SE tax on all $150,000, you pay yourself a reasonable salary (say, $90,000) - subject to payroll taxes - and take the remaining $60,000 as a distribution, which is not subject to SE tax. At $150,000 in profit, that saves roughly $8,000–$9,000 per year. The break-even point for most businesses is around $60,000–$70,000 in net profit. Below that, the administrative costs (payroll system, Form 1120-S, quarterly filings) often outweigh the savings. To get S-Corp treatment for the 2026 tax year, you need to file Form 2553 by March 15, 2026 for calendar-year businesses.
SE tax rate 2026: 15.3% on first $184,500 of net earnings
Distributions from S-Corp: not subject to SE tax
Typical annual savings: $5,000–$15,000 at $100K–$200K net profit
Requires: payroll setup, quarterly Form 941, annual Form 1120-S
Deadline to elect S-Corp for 2026: March 15, 2026 (Form 2553)
Strategy 4: Max Out Retirement Plan Contributions
Pre-tax retirement contributions that slash your taxable income
Retirement contributions are one of the largest and most overlooked deductions for small business owners. Every dollar you put in reduces your taxable income dollar for dollar. In 2026, contribution limits are at their highest ever. A Solo 401(k) lets you contribute as both employee (up to $23,500) and employer (up to 25% of net self-employment income), for a combined maximum of $70,000 - or $81,250 if you're between ages 60–63 under the SECURE 2.0 'super catch-up' rules. A SEP-IRA is simpler to manage and allows contributions up to 25% of compensation, capped at $72,000 for 2026 (up from $70,000 in 2025). A SIMPLE IRA caps at $17,000 employee contributions in 2026 ($21,000 with catch-up if you're 50+). If you're in the 24% federal bracket, contributing $50,000 to a Solo 401(k) saves you $12,000 in federal tax - immediately. That doesn't include state taxes or the effect on your SE tax calculation.
Solo 401(k) 2026: up to $70,000 combined employee + employer contributions
Ages 60–63: 'super catch-up' boosts Solo 401(k) limit to $81,250
SEP-IRA 2026: up to $72,000 (25% of compensation, max $360,000 eligible comp)
SIMPLE IRA 2026: $17,000 employee limit + $4,000 catch-up for age 50+
Contributions reduce QBI income, which can affect the 23% QBI deduction - plan carefully
Retirement Plan Limits at a Glance - 2026
Solo 401(k)
Up to $70,000 combined. Employee deferral: $23,500. Employer contribution: 25% of net self-employment income. Ages 60–63 can contribute up to $81,250. Best for self-employed with no full-time employees.
SEP-IRA
Up to $72,000 or 25% of compensation (whichever is less). Easy to set up, low admin overhead. Only employer contributes - employees cannot make their own deferrals. Can be opened up to the tax filing deadline.
SIMPLE IRA
$17,000 employee limit in 2026 (+$4,000 catch-up for age 50+). Good for businesses with employees. Both employer and employees contribute. Must be set up by October 1 of the plan year.
Defined Benefit Plan
Best for high earners (over $200K). Can shelter far more than any defined contribution plan. Actuarially calculated contributions - can reach $280,000+ per year. High setup and admin cost, but the deduction is massive.
Strategy 5: Deduct Your Home Office
A legitimate deduction that most small business owners miss
If you use a part of your home regularly and exclusively for business - and it's your principal place of business - you can deduct those costs. There are two methods. The simplified method: $5 per square foot, up to 300 square feet = maximum $1,500 deduction per year, no recordkeeping for utilities or mortgage. The actual expense method: multiply total home expenses (rent or mortgage interest, utilities, insurance, repairs) by the percentage of your home used for business. A 200 sq ft office in a 2,000 sq ft home = 10% business use. If total annual housing costs are $30,000, that's a $3,000 deduction. For S-Corp owners, the rules differ. You cannot claim home office on Schedule C if you're paid through an S-Corp. Instead, your S-Corp sets up an accountable plan to reimburse you for home office expenses - which are then deductible by the corporation and tax-free to you. This requires written documentation and a formal accountable plan.
Simplified method: $5/sq ft × up to 300 sq ft = max $1,500
Actual expense method: (office sq ft ÷ home sq ft) × total housing costs
Space must be used regularly AND exclusively for business
W-2 employees cannot claim this deduction - self-employed and LLC/S-Corp owners only
S-Corp owners: use an accountable plan for reimbursement, not Schedule C
Strategy 6: Track Every Business Mile
The 2026 standard mileage rate is 72.5 cents
The IRS standard mileage rate for 2026 is 72.5 cents per mile - up from prior years. Drive 15,000 business miles in a year and that's a $10,875 deduction, with no receipt tracking needed beyond a mileage log. Alternatively, the actual expense method lets you deduct the business-use percentage of all vehicle costs: gas, insurance, repairs, registration, and depreciation (or Section 179). If you drive an expensive vehicle mostly for business, the actual method often yields a larger deduction. You cannot switch methods mid-year. Choose at the start of the tax year and keep daily mileage logs with dates, destinations, and business purpose.
2026 standard mileage rate: $0.725 per business mile
10,000 miles = $7,250 deduction; 20,000 miles = $14,500 deduction
Required recordkeeping: date, destination, business purpose, miles driven
Heavy vehicles (6,000+ lbs GVWR): consider combining Section 179 + 100% bonus depreciation instead
Cannot use standard mileage rate if you claimed accelerated depreciation on the vehicle
Strategy 7: Deduct 100% of Health Insurance Premiums
Self-employed health insurance: fully deductible above the line
If you are self-employed and not eligible for coverage through a spouse's employer, you can deduct 100% of health, dental, vision, and long-term care insurance premiums for yourself, your spouse, and dependents. This is an above-the-line deduction - it reduces your adjusted gross income (AGI), not just your itemized deductions, which makes it more valuable. The deduction cannot exceed your net self-employment income for the year. For S-Corp owners: if your corporation pays or reimburses your premiums and includes them on your W-2, you can deduct them on your personal return. Pair this with a Health Savings Account (HSA) if you're enrolled in a high-deductible health plan - HSA contributions are also pre-tax, grow tax-free, and withdrawals for qualified medical expenses are completely tax-free.
100% deductible for self-employed (not available to W-2 employees)
Covers: health, dental, vision, and long-term care insurance
Reduces AGI - not just itemized deductions
Cannot exceed net self-employment income for the year
Stack with HSA contributions: triple tax-advantaged savings (pre-tax in, tax-free growth, tax-free out for medical)
Strategy 8: Use the Increased SALT Deduction
SALT cap tripled to $40,000 in 2026
The state and local tax (SALT) deduction cap increased from $10,000 to $40,000 for 2026 under the OBBBA, with the cap continuing to rise 1% annually through 2029. For small business owners in high-tax states like California, New York, New Jersey, or Illinois, this is a major change. If you pay $25,000 in state income tax and $15,000 in property tax, you can now deduct the full $40,000 - versus only $10,000 before. For pass-through entity owners, many states also offer a Pass-Through Entity (PTE) tax election that lets the business itself pay state income tax, which is then deductible at the federal level. This can effectively let you bypass the personal SALT cap altogether. Talk to a CPA about whether your state offers this and whether it makes sense for your situation.
2026 SALT cap: $40,000 (up from $10,000)
Cap rises 1% annually through 2029, then reverts to $10,000 in 2030
Includes state income tax, local income tax, and property taxes
PTE (Pass-Through Entity) election: deduct state business taxes at the entity level, bypassing the personal SALT cap
Most valuable for owners in high-tax states (CA, NY, NJ, IL, MA)
Strategy 9: Deduct Business Meals (50%) and Marketing (100%)
Everyday expenses you may be missing
Business meals with clients, partners, or employees where business is actively discussed are 50% deductible in 2026. Entertainment expenses (concerts, sporting events) are generally not deductible. Keep records that show who attended, the business purpose, and the amount. Marketing and advertising costs are 100% deductible - website design, digital ads, printed materials, email marketing software, SEO services, sponsorships. Professional development is also fully deductible: courses, certifications, conference fees, industry subscriptions, and professional association dues. Business insurance premiums, accounting software, bookkeeping services, and legal fees are all ordinary and necessary business expenses - deductible in full.
Business meals: 50% deductible - document who attended and the business purpose
Marketing and advertising: 100% deductible
Professional development (courses, certifications, conferences): 100% deductible
Accounting, legal, and professional services: 100% deductible
Business insurance premiums: 100% deductible
Strategy 10: Hire Family Members
Income shifting to lower tax brackets - legally
If your children or spouse do real work for your business, paying them a reasonable salary shifts income to a lower tax bracket and creates a deductible business expense. A child under 18 employed by a sole proprietor or partnership owned by their parents is exempt from Social Security and Medicare taxes on those wages. If the child earns $14,600 or less (the 2026 standard deduction), they pay zero federal income tax on that income - while you deduct the wages from your business income taxed at 24%, 32%, or higher. Your wages must be: reasonable for the work performed, documented with time logs and job descriptions, paid through a real payroll process (check or direct deposit, not cash). For S-Corp or C-Corp owners, the FICA exemption for family members doesn't apply - but the income-shifting benefit still does.
Wages to children: deductible business expense for you, often zero tax for them
Children under 18 in a sole proprietorship or partnership: exempt from FICA taxes
Standard deduction 2026: $16,100 for single filers - wages up to this amount are federally tax-free for your child
Work must be real: document job duties, hours, and pay rate
Spouse wages: deductible + both spouses build Social Security credits
Strategy 11: Time Your Income and Deductions
Defer income and accelerate deductions in high-income years
Tax planning is largely about timing. If you expect higher income this year than next, defer invoicing or push year-end payments into January. Prepay deductible expenses in December - subscription renewals, insurance premiums, office supplies - to pull deductions into the current year. If you're a cash-basis taxpayer (most small businesses are), income is recognized when received and expenses when paid. This gives you real control. One powerful move: prepay a business expense like an annual software subscription, insurance, or even rent one month in advance before December 31. For equipment purchases, place the asset in service by December 31 to claim Section 179 or bonus depreciation for the current year. Ordering equipment in November but receiving it after December 31 moves the deduction to next year.
Defer income: delay year-end invoicing if next year's tax rate will be lower
Accelerate deductions: prepay deductible expenses before December 31
Section 179 / bonus depreciation: asset must be placed in service by December 31 of the tax year
Retirement contributions: Solo 401(k) employee deferrals due December 31; SEP-IRA can be funded up to tax filing deadline
Estimated taxes: if you overpay Q4, you reduce cash flow - time payments to avoid underpayment penalty only
Strategy 12: Set Up an Accountable Plan for Employee Expenses
Reimburse business expenses tax-free through your S-Corp or corporation
An accountable plan is a formal reimbursement policy that lets a business pay back employee business expenses - including home office, vehicle, phone, and equipment - without those reimbursements being treated as taxable income. The business deducts the reimbursement; the employee pays no tax on it. For S-Corp owners, this is the standard way to capture home office deductions. Without an accountable plan, any reimbursements become taxable W-2 wages. Three IRS requirements for an accountable plan: (1) expenses must have a business connection, (2) employees must substantiate expenses with receipts and documentation within a reasonable time, (3) any excess must be returned. Processing fees, phone and internet costs (proportional to business use), professional subscriptions, and travel expenses all qualify. This works for any entity type: sole proprietorships with employees, partnerships, S-Corps, and C-Corps.
Reimbursements under an accountable plan: tax-free to employee, deductible for the business
Without an accountable plan: reimbursements become taxable W-2 income
S-Corp owners must use accountable plan for home office - cannot claim on Schedule C
Qualifies for: home office, vehicle (mileage or actual), phone, internet, travel, equipment
Requires: written plan document, receipts, submission within reasonable time
Key 2026 Tax Changes Small Business Owners Need to Know
QBI Deduction: Permanent and Raised to 23%
The Section 199A deduction was set to expire after 2025. OBBBA made it permanent and increased the rate from 20% to 23% starting with the 2026 tax year. New $400 minimum deduction for businesses with at least $1,000 in QBI.
Section 179 Limit: Up to $2,560,000
More than doubled from the prior $1,250,000 cap. Phase-out begins at $4,090,000 in purchases. Both limits are now indexed to inflation annually. Combined with 100% bonus depreciation, most small businesses can write off equipment 100% in year one.
100% Bonus Depreciation: Permanent
Was phasing down - 80% in 2023, 60% in 2024 - and heading lower. OBBBA permanently restored 100% bonus depreciation for property placed in service after January 19, 2025. Applies to both new and used qualifying property.
SALT Cap: $40,000 (from $10,000)
State and local tax deduction cap tripled for 2026. Particularly impactful for business owners in California, New York, New Jersey, and Illinois. Cap rises 1% per year through 2029, then reverts to $10,000 in 2030.
SEP-IRA Limit: $72,000
Up $2,000 from 2025. Solo 401(k) employer + employee combined maximum is $70,000 ($81,250 for ages 60–63). SIMPLE IRA employee limit rises to $17,000. All limits are now indexed to inflation.
Standard Mileage Rate: 72.5 Cents
Up from prior years, reflecting higher vehicle operating costs. Business owners who drive frequently for work should log every mile - 20,000 annual business miles equals $14,500 in deductions with zero receipt tracking.

Frequently Asked Questions
What is the most valuable tax deduction for small businesses in 2026?
For most small businesses, the QBI deduction (23% of net business income) and retirement plan contributions together produce the largest dollar savings. A business owner earning $150,000 in net profit saves roughly $34,500 through QBI alone. Add a $50,000 SEP-IRA or Solo 401(k) contribution and you've cut taxable income by over half before touching other deductions.
What is the QBI deduction and how does it work in 2026?
The Qualified Business Income (QBI) deduction lets pass-through business owners (sole proprietors, LLCs, S-Corps, partnerships) deduct 23% of their net qualified business income from their personal return. It's an above-the-line deduction - you don't need to itemize. For 2026, it's permanent (made so by OBBBA), and a new $400 minimum applies if you have at least $1,000 in QBI. Phase-outs begin at $75,000 (single) / $150,000 (joint) for specified service trades.
How does the S-Corp election save on taxes?
As a sole proprietor or single-member LLC, you pay 15.3% self-employment tax on all net income. An S-Corp lets you split income into salary (subject to SE tax) and distributions (not subject to SE tax). At $150,000 in net profit with a $90,000 salary, you avoid SE tax on $60,000 - saving roughly $8,000–$9,000 annually. The savings must be weighed against administrative costs (payroll, Form 1120-S, quarterly filings). The break-even for most businesses is around $60,000–$70,000 in net annual profit.
What is Section 179 and what are the limits for 2026?
Section 179 lets you expense the full purchase price of qualifying business equipment, vehicles, and software in the year you place it in service - instead of depreciating over 5–7 years. For 2026, the limit is $2,560,000 with a phase-out starting at $4,090,000. This is nearly double the pre-2025 limit of $1,250,000. Combined with 100% bonus depreciation (also permanent as of OBBBA), most businesses can now write off capital purchases 100% in year one.
Can I deduct home office expenses if I'm self-employed?
Yes - if you use the space regularly and exclusively for business, and it's your principal place of business. Simplified method: $5/sq ft × up to 300 sq ft = $1,500 max. Actual method: (office sq ft ÷ home sq ft) × total housing costs. W-2 employees cannot claim this deduction. S-Corp owners cannot claim it on Schedule C either - your S-Corp must use an accountable plan to reimburse you instead.
What are the retirement contribution limits for small business owners in 2026?
Solo 401(k): up to $70,000 combined ($81,250 if ages 60–63). SEP-IRA: up to $72,000 (25% of compensation). SIMPLE IRA: $17,000 employee limit (+$4,000 catch-up for age 50+). All contributions reduce your taxable income dollar-for-dollar. A $70,000 Solo 401(k) contribution in the 24% bracket saves $16,800 in federal tax - plus the impact on state income tax and SE tax.
What changed for small business taxes under the One Big Beautiful Bill Act (OBBBA)?
OBBBA (signed July 4, 2025) made four major changes for small businesses: (1) QBI deduction made permanent and raised from 20% to 23% starting 2026; (2) Section 179 limit more than doubled to $2.5M; (3) 100% bonus depreciation permanently restored; (4) SALT deduction cap tripled from $10,000 to $40,000. Additionally, domestic R&D expenses are immediately deductible again, and the employer childcare credit expanded to 40–50% of eligible costs up to $500,000–$600,000.
What is the standard mileage rate for business driving in 2026?
The IRS standard mileage rate for business use in 2026 is 72.5 cents per mile. Drive 10,000 miles for business and you can deduct $7,250 with no need to track individual gas or repair receipts - just a mileage log with dates, destinations, and business purpose. Alternatively, you can deduct the actual business-use percentage of all vehicle costs (gas, insurance, maintenance, depreciation), which is better for expensive vehicles.
