12 Proven Ways Business Owners Can Reduce Their Tax Bill (LLC, S Corp, Partnership & C Corp)

Every dollar you overpay in taxes is a dollar that could be reinvested in your business, paid to yourself, or saved for retirement. The good news: the tax code is full of legal, IRS-approved strategies that most business owners never fully use.

This guide covers 12 of the most effective tax reduction strategies available to LLC, S Corp, partnership, and C Corp owners in New York and New Jersey. These are not loopholes — they are provisions Congress wrote specifically to benefit business owners. The key is knowing which ones apply to your entity type and acting before the deadlines.

1. Elect S Corp Status to Eliminate Self-Employment Tax on a Portion of Your Income

Best for: LLCs and sole proprietors earning $50,000+ in net profit

This is one of the single largest tax-saving moves available to small business owners. By default, LLC members and sole proprietors pay self-employment (SE) tax — 15.3% — on every dollar of net profit. That's on top of income tax.

When you elect S Corp status (either by forming an S Corp or by filing Form 2553 to have your LLC taxed as an S Corp), you split your income into two buckets:

• Reasonable salary — subject to payroll taxes (SE equivalent)
• Distributions — not subject to self-employment tax

Example: If your LLC earns $150,000 in net profit and you pay yourself a reasonable salary of $80,000, only the $80,000 is subject to SE tax. The remaining $70,000 in distributions is not. At 15.3%, that's roughly $10,710 in annual savings — before income tax.

The S Corp election has costs (payroll setup, Form 1120-S, K-1s), so the math needs to work. Generally, it makes sense when net profit exceeds $50,000–$60,000 per year. Our enrolled agents can run the numbers for your specific situation.

2. Maximize Retirement Plan Contributions

Best for: All entity types

Contributions to qualified retirement plans are deductible — dollar for dollar — against your business income. The limits are generous, and many business owners leave significant money on the table by not maxing them out.

2026 contribution limits:

Plan	Employee Contribution	Total Limit (with employer match)
SEP-IRA	N/A	25% of compensation, up to $69,000
Solo 401(k)	$23,000 ($30,500 if 50+)	Up to $69,000
SIMPLE IRA	$16,000 ($19,500 if 50+)	Up to $19,500
Defined Benefit Plan	Varies	Up to $275,000

A Solo 401(k) is particularly powerful for self-employed owners: you can contribute as both the employee (up to $23,000) and the employer (up to 25% of compensation), stacking contributions up to $69,000 per year.

Important: SEP-IRA contributions can be made up to the tax filing deadline (including extensions). Solo 401(k) plans must be established by December 31 of the tax year, even if contributions are made later.

3. Deduct the Full Cost of Equipment in Year One (Section 179 and Bonus Depreciation)

Best for: All entity types purchasing equipment, vehicles, or technology

Normally, business assets are depreciated over their useful life — a computer over 5 years, a vehicle over 5 years, office furniture over 7 years. But two provisions let you deduct the full cost in the year of purchase:

Section 179: Allows you to immediately expense up to $1,220,000 (2026 limit) of qualifying business property placed in service during the year. Applies to equipment, machinery, computers, software, and certain vehicles.

Bonus Depreciation: Currently at 60% for 2026 (phasing down from 100% in 2022). Applies to new and used property with a recovery period of 20 years or less. Unlike Section 179, bonus depreciation can create a net operating loss.

Practical example: You purchase a $40,000 work truck in November 2026. Instead of deducting ~$8,000/year over 5 years, you can deduct the full $40,000 this year under Section 179 — reducing your taxable income by $40,000 immediately.

Note: Bonus depreciation is phasing down — 40% in 2027, 20% in 2028, then gone. If you're planning a major equipment purchase, sooner is better.

4. Take the Qualified Business Income (QBI) Deduction

Best for: LLCs, S Corps, and partnerships (pass-through entities)

The QBI deduction (Section 199A) allows eligible pass-through business owners to deduct up to 20% of qualified business income from their taxable income. This is one of the most significant deductions created by the Tax Cuts and Jobs Act.

How it works:

• If your taxable income is below $197,300 (single) or $394,600 (married filing jointly) in 2026, you generally qualify for the full 20% deduction with no restrictions
• Above those thresholds, limitations apply based on W-2 wages paid and the type of business
• Specified Service Trades or Businesses (SSTBs) — including law, consulting, and financial services — face additional phase-out rules at higher income levels

Example: Your S Corp generates $200,000 in qualified business income. You may be able to deduct $40,000 (20%) from your taxable income — saving roughly $8,800–$14,800 in federal income tax depending on your bracket.

This deduction is currently set to expire after 2025 unless Congress extends it. As of this writing, extension legislation is pending. Your tax professional can help you plan around the uncertainty.

5. Deduct the Pass-Through Entity Tax (PTET) — A Major Win for NY and NJ Owners

Best for: S Corps, partnerships, and LLCs taxed as partnerships or S Corps in New York and New Jersey

The PTET is one of the most valuable — and most overlooked — deductions available to business owners in New York and New Jersey. Here's why it matters:

The 2017 Tax Cuts and Jobs Act capped the federal deduction for state and local taxes (SALT) at $10,000 per individual. For business owners in high-tax states like NY and NJ, this was a significant hit.

The PTET is the workaround. By electing to pay state income tax at the entity level (rather than the individual level), the business gets a full federal deduction for the state tax paid — bypassing the $10,000 SALT cap entirely.

New York PTET: Available to S Corps and partnerships. The tax rate ranges from 6.85% to 10.9% depending on income. The entity pays the tax; partners/shareholders receive a credit on their personal returns.

New Jersey PTET (BAIT): New Jersey's Business Alternative Income Tax (BAIT) works similarly. Rates range from 5.675% to 10.9%.

The net result: A business owner in New York paying $50,000 in state income tax through the PTET gets a full $50,000 federal deduction — potentially saving $11,000–$18,500 in federal tax depending on their bracket. Without the PTET election, that same $50,000 would be largely non-deductible due to the SALT cap.

The PTET election must be made by a specific deadline each year. In New York, the election is due by March 15 for calendar-year entities. Missing the deadline means losing the deduction for the entire year.

6. Hire Your Children (Legitimately)

Best for: Sole proprietors, single-member LLCs, and partnerships owned by spouses

If you have children under 18, you can pay them a reasonable wage for legitimate work performed in your business. The wages are deductible as a business expense — and if your child earns less than the standard deduction ($14,600 in 2026), they pay zero federal income tax on those earnings.

The tax math:

• You deduct the wages at your marginal rate (say, 32%) — saving $3,200 on $10,000 paid
• Your child pays zero tax on the first $14,600 earned
• Net family tax savings: $3,200+ per year

Important rules:

• The work must be real and the wage must be reasonable for the work performed
• For sole proprietors and single-member LLCs: wages paid to children under 18 are also exempt from FICA (Social Security and Medicare) taxes
• This exemption does not apply to C Corps or S Corps — payroll taxes still apply in those structures

Legitimate jobs for children in a business include: filing, data entry, social media management, photography, cleaning, delivery, and administrative tasks.

7. Deduct Health Insurance Premiums

Best for: S Corp shareholders owning more than 2%, sole proprietors, and single-member LLC owners

Self-employed business owners can deduct 100% of health insurance premiums paid for themselves, their spouse, and their dependents — directly reducing adjusted gross income (AGI).

How it works by entity type:

• Sole proprietors and single-member LLCs: Deduct premiums on Schedule 1 of Form 1040 (above-the-line deduction)
• S Corp shareholders (>2% ownership): The S Corp must include the premium in your W-2 wages, then you deduct it on your personal return. The setup matters — if done incorrectly, the deduction is lost
• C Corp owner-employees: The corporation deducts premiums as a business expense; they are excluded from the employee's income entirely — the most favorable treatment of any entity type
• Partnerships: Partners deduct premiums on their personal returns via a guaranteed payment

This deduction can be worth $5,000–$25,000+ per year depending on your family's coverage costs.

8. Establish and Fund a Health Savings Account (HSA)

Best for: Business owners enrolled in a High-Deductible Health Plan (HDHP)

If you're covered by a qualifying high-deductible health plan, you can contribute to a Health Savings Account (HSA) and deduct every dollar contributed — regardless of whether you itemize.

2026 HSA contribution limits:

• Individual coverage: $4,300
• Family coverage: $8,550
• Catch-up contribution (age 55+): additional $1,000

HSA contributions are triple tax-advantaged: deductible when contributed, grow tax-free, and are tax-free when withdrawn for qualified medical expenses. Unused funds roll over indefinitely — there's no "use it or lose it" rule.

For a business owner in the 32% bracket contributing $8,550 for family coverage, the federal tax savings alone are $2,736 — plus state tax savings on top.

9. Deduct Home Office Expenses

Best for: Business owners who use part of their home regularly and exclusively for business

If you have a dedicated space in your home used regularly and exclusively for business, you can deduct a portion of your home expenses — mortgage interest or rent, utilities, insurance, repairs, and depreciation.

Two calculation methods:

1. Simplified method: $5 per square foot of dedicated office space, up to 300 sq ft (maximum $1,500 deduction)
2. Regular method: Calculate the percentage of your home used for business (office sq ft ÷ total home sq ft) and apply that percentage to actual home expenses. This often yields a larger deduction but requires more recordkeeping

Important: The space must be used exclusively for business — a guest bedroom that doubles as an office does not qualify. A dedicated room used only for business does.

For S Corp shareholders, the home office deduction works differently — the corporation must reimburse you under an accountable plan, and the reimbursement is deductible by the corporation.

10. Accelerate Deductions / Defer Income (Timing Strategies)

Best for: Cash-basis businesses approaching year-end

For cash-basis taxpayers (most small businesses), income is recognized when received and expenses are deducted when paid. This gives you meaningful control over your taxable income in any given year.

Accelerate deductions into the current year:

• Prepay January rent in December
• Pay Q4 estimated state taxes before December 31 (subject to SALT cap for individuals)
• Purchase and place in service equipment before year-end
• Pay outstanding vendor invoices before December 31
• Make charitable contributions through the business (if structured correctly)

Defer income into the next year:

• Delay sending invoices for work completed in late December until January
• Negotiate to receive a large payment in January rather than December
• Defer bonuses to January (if the business can afford to)

Caution: These strategies make sense when you expect to be in the same or lower tax bracket next year. If you expect higher income next year, the calculus reverses.

11. Use a Defined Benefit Plan for Very High Earners

Best for: High-income business owners (typically $200,000+ net profit) with no or few employees

For business owners who have maxed out their 401(k) and still want to shelter more income, a Defined Benefit (DB) plan can allow contributions of up to $275,000 per year — far exceeding the $69,000 Solo 401(k) limit.

A DB plan promises a specific retirement benefit and requires annual actuarial calculations. The contribution required each year depends on your age, income, and the promised benefit. Older business owners can contribute more because they have fewer years to fund the benefit.

Example: A 55-year-old business owner with $400,000 in net profit might be able to contribute $200,000+ to a DB plan in a single year — reducing taxable income by the same amount.

DB plans are more complex and expensive to administer than 401(k)s, but for the right profile (high income, older owner, few employees), the tax savings can be extraordinary.

12. C Corp-Specific Strategy: Retain Earnings at the 21% Flat Rate

Best for: C Corp owners who don't need to distribute all profits personally

C Corporations pay a flat 21% federal income tax rate on all profits — regardless of how much the corporation earns. For high-income owners who would otherwise pay 32%, 35%, or 37% on pass-through income, retaining earnings inside a C Corp can result in significant tax deferral.

How it works:

• The C Corp pays 21% on retained earnings
• The owner does not pay personal income tax on those earnings until they are distributed as dividends or the business is sold
• In the meantime, the retained earnings can be reinvested in the business, used to fund equipment purchases, or held as working capital

The trade-off: When earnings are eventually distributed as dividends, they are taxed again at the qualified dividend rate (0%, 15%, or 20% depending on income) — the so-called "double taxation" of C Corps. The strategy works best when the owner plans to reinvest profits rather than distribute them, or when the business will be sold (triggering capital gains rates rather than ordinary income rates).

C Corps also have access to certain fringe benefits — like fully deductible health insurance for owner-employees and group term life insurance — that are not available in the same form to pass-through entities.

The Bottom Line

No single strategy works for every business. The right combination depends on your entity type, income level, number of employees, state of residence, and personal financial goals.

What's consistent across all of them: the earlier you act, the more options you have. Many of these strategies — retirement plan establishment, PTET elections, equipment purchases — have hard deadlines. Waiting until April to think about last year's taxes means most of these windows are already closed.
