Let's start with an uncomfortable truth.
The IRS isn't your enemy. But the system isn't designed to help you pay less. It's designed to collect. Every deduction, credit, and strategy in this guide is completely legal — written directly into the tax code. But nobody's going to hand them to you.
Not because they're doing anything wrong. Not because their accountant is incompetent. Because:
This guide covers specific, legal, documented strategies that the IRS explicitly allows. We'll cover the fundamentals you might be getting wrong, strategies most people miss entirely, and advanced moves that separate businesses paying 35%+ effective rates from those paying 18–22%.
One important note before we dive in: Tax law changes. This guide reflects 2024 tax year rules. Always verify current numbers with your CPA or at IRS.gov before making decisions.
Let's keep more money.
Before we talk about deductions, you need to understand the system you're working within. The rules are different depending on how your business is structured.
The default for most freelancers and new businesses. All profit flows to your personal tax return on Schedule C. You pay:
If you net $100,000 as a sole prop, you're paying ~$14,130 in self-employment tax before income tax even starts. This is one of the biggest reasons to consider S-Corp status above ~$40K profit.
This is where it gets interesting. S-Corps are pass-through entities (income flows to your personal return), but you split income between W-2 salary and distributions. You only pay payroll taxes on the salary portion — not on distributions. This is the S-Corp tax strategy and we'll break it down fully in Chapter 10.
C-Corps pay tax at the entity level — flat 21% federal corporate rate. Then shareholders pay tax again on dividends ("double taxation"). Usually not ideal for small businesses, but with specific advantages for certain situations.
Reduce taxable income. A $10,000 deduction at the 32% bracket saves $3,200.
Reduce taxes owed dollar-for-dollar. A $10,000 credit saves $10,000. Always more valuable.
For pass-through businesses, every dollar you deduct saves you money at your marginal rate — the rate on your highest dollars. If you're in the 32% bracket, a $10,000 deduction saves you $3,200 in federal income tax, plus whatever your state rate is.
If you use part of your home regularly and exclusively for business, you can deduct it. Those two words are what make or break this deduction.
$5 per square foot × up to 300 sq ft = max $1,500 deduction
Simple, no depreciation tracking, no recapture.
Office % of home × all home expenses (rent/mortgage, utilities, insurance, depreciation)
Almost always yields more.
Claiming home office on a space that's not exclusively used for business is one of the most audited deductions. The room needs to be only your office. Keep it legitimate.
Drive 20,000 business miles = $13,400 deduction. Simple to track, no need to log gas/maintenance separately.
Track all costs (gas, insurance, maintenance, repairs, registration, depreciation) and deduct the business-use percentage.
The IRS requires a contemporaneous mileage log. You cannot reconstruct this at year-end. Track in real time: date, start/end miles, destination, business purpose. Use MileIQ, Everlance, or TripLog — they're automatic.
| Category | Deductible % | Notes |
|---|---|---|
| Business meals with clients (business discussed) | 50% | Document: date, who, purpose |
| Meals during business travel | 50% | Receipts required |
| Office parties (all employees) | 100% | Must include all staff |
| Entertainment (concerts, golf, sports) | 0% | Not deductible post-TCJA |
Primary purpose test: If the trip is primarily for business, travel costs are deductible even with some personal time. Fly to a conference Tue–Thu and stay through Sunday for vacation — airfare is still deductible. Extra hotel nights and weekend meals are personal.
| International Travel | Deductible |
|---|---|
| 75%+ of days are business days | 100% of travel costs |
| 25–75% business days | Prorated |
| Under 25% business days | No travel deduction |
These are the ones that add up to thousands of dollars in missed deductions every year.
Every subscription you pay for your business is deductible. This category is massively underreported. Common missed deductions:
Many business owners are surprised when they total annual subscriptions — often $3,000–$10,000 per year for a typical digital business. 100% deductible.
If education maintains or improves skills for your current business, it's deductible:
Self-employed individuals not eligible for employer coverage can deduct 100% of health insurance premiums for themselves, spouse, and dependents. This is an "above the line" deduction — reduces your AGI even without itemizing.
Deduct your business-use percentage:
On a $200,000 revenue business using Stripe, you're paying roughly $6,000/year in processing fees — fully deductible and completely missed by many owners.
This is one of the most powerful — and least known — strategies for business owners.
If you rent your personal residence for fewer than 15 days in a tax year, you don't report that rental income on your federal taxes. Zero. The income is completely excluded.
It was nicknamed the "Augusta Rule" because homeowners in Augusta, Georgia rent their homes during the Masters golf tournament — charging $10,000–$30,000 per week and keeping it all tax-free.
As a business owner, you can rent your home to your own business for meetings, strategy retreats, team events, or similar uses — up to 14 days per year.
S-Corp and C-Corp owners get the cleanest setup — a corporate entity pays rent to you personally. Sole proprietors can technically use this, but it's messier and scrutinized more. Consult your CPA.
For sole proprietors and parent-owned partnerships, employing children under 18 provides significant tax advantages:
The FICA exemption does NOT apply if your business is incorporated. Your child's wages will be subject to payroll taxes. Still potentially beneficial for income shifting, but run the numbers.
Benefits of legitimate spousal employment:
Reality check: Spousal employment is scrutinized. Spouse must do real work, wages must be reasonable, keep time records, process actual payroll.
If there's one category where business owners systematically leave the most money on the table, it's retirement plans. The money doesn't disappear — it goes to you. You're building wealth while legally deferring taxes.
Net SE income of $200,000 → max SEP-IRA contribution ≈ $46,587. At 32% bracket: ~$14,900 in federal tax savings.
Earning $300,000+? A defined benefit plan can allow contributions of $100,000–$275,000 per year depending on age and income. Trade-off: complex, $2,000–$5,000/year in actuarial fees. Extraordinary for the right profile.
| Situation | Recommended Plan |
|---|---|
| Solo, want simple | SEP-IRA |
| Solo, want max contribution at lower income | Solo 401(k) |
| Solo, want Roth option | Solo 401(k) |
| Have employees | SIMPLE IRA or 401(k) |
| Earning $300K+, want to shelter maximum | Defined Benefit Plan |
2024 limit: $1,220,000 (phase-out starts when total purchases exceed $3,050,000). Deduct the entire cost of qualifying equipment in the year of purchase instead of depreciating over years.
Vehicles with GVWR over 6,000 lbs qualify for much larger deductions than regular passenger vehicles.
Popular qualifying vehicles: Ford F-150, Chevy Suburban, GMC Yukon, Range Rover, Cadillac Escalade, most heavy pickup trucks. Business use must be genuine and logged.
| Year | Bonus Depreciation % | Note |
|---|---|---|
| 2024 | 60% | Current year |
| 2025 | 40% | Phasing down |
| 2026 | 20% | Nearly gone |
| 2027 | 0% | Expires under current law* |
*Legislative changes proposed — verify current status with your CPA.
Section 199A lets eligible business owners deduct up to 20% of qualified business income from taxable income. This is in addition to all other deductions — just for being a pass-through business owner rather than a W-2 employee.
| Income Level | Single Filer | Joint Filer |
|---|---|---|
| Full 20% deduction (no limits) | Under $191,950 | Under $383,900 |
| Phase-out range | $191,950 – $241,950 | $383,900 – $483,900 |
| Above phase-out: SSTB loses deduction | Over $241,950 | Over $483,900 |
Certain professional service businesses face additional restrictions above the income thresholds:
Under the thresholds: SSTBs get the full 20% — same as everyone else.
Above the phase-out: SSTBs get zero. Non-SSTBs use the W-2 wage/property limitation formula.
Business owner with $150,000 net business income (under thresholds):
QBI deduction: $30,000
Tax savings at 22%: $6,600
Tax savings at 24%: $7,200
No spending required. Just pass-through status.
Note: The QBI deduction is set to expire after 2025 under TCJA. Significant legislative discussion about extension is ongoing. Verify current status with your CPA.
| Structure | SE/Payroll Tax | Pass-Through | Corporate Tax | Best For |
|---|---|---|---|---|
| Sole Prop / SMLLC | Full 15.3% | Yes | None | Starting out, <$50K profit |
| Multi-Member LLC | Full 15.3%* | Yes | None | Multiple owners |
| S-Corporation | Salary only | Yes | None | $50K+ profit |
| C-Corporation | N/A | No | 21% flat | High growth, investors |
The IRS requires you to pay yourself what you'd pay someone else for the same work. CPAs generally recommend 40–60% of net profit as salary, or use market comparables for your role. Document your salary benchmark.
When net business profit consistently exceeds $40,000–$50,000 per year. Below that, payroll administration costs ($1,500–$3,000/year extra) may exceed the savings.
Most business owners think R&D credits are for labs. They're not. Software companies, app developers, engineers, manufacturers, and any business doing technical experimentation may qualify.
Federal credit of $2,400–$9,600 per qualified new hire from target groups:
This paperwork requirement is why most employers miss WOTC. Submit pre-screening form to your State Workforce Agency within 28 days of the employee's start date.
Under 25 full-time equivalent employees, average wages below $62,000, paying at least 50% of premiums: up to 50% credit on premiums paid.
For cash-basis businesses, when income and expenses are recognized can be just as important as what you deduct. You have legitimate control over timing.
Selling a business asset with a large gain? Structure as an installment sale: receive payments over multiple years, report gain proportionally, keep income in lower brackets each year.
SEP-IRAs can be funded up to October 15 (for those who file extensions). You can make the contribution decision after you know your actual income for the year — enormous flexibility for variable-income businesses.
Do these by December 31:
Your CPA is valuable. But most CPAs focus primarily on compliance (filing accurate returns), not proactive tax planning. Here's how to change that.
A great CPA/tax advisor is worth their fee many times over. A mediocre one costs you money every year. The right CPA for a business owner is proactive, asks questions, and thinks about your total tax picture — not just this year's return.
