Are consulting fees I pay to subcontractors deductible?

Yes — 100% deductible on Line 11. Collect a W-9 from each subcontractor and file a 1099-NEC if you pay them $600 or more in a year.

Can I deduct first-class flights for client travel?

The IRS allows ordinary and necessary travel expenses. First-class may be questioned if coach is a practical alternative — business class on long flights is generally accepted; lavish personal upgrades are not.

Is a standing desk or ergonomic chair deductible?

Yes — office furniture for your home office is deductible as equipment (Line 13) in the year of purchase using Section 179.

Should I form an S-Corp to reduce self-employment tax?

Many consultants earning $60,000+ net profit save on self-employment tax by electing S-Corp status. Consult a CPA — the savings can be $3,000–$8,000 per year, but there are payroll and compliance costs.

Tax Write-Offs for Consultants

Independent business, strategy, and management consultants typically have some of the highest deductible expenses of any self-employed professional. Travel, client meals, home offices, and technology subscriptions all reduce taxable income — and consultants often have significant amounts of each.

Top 6 Tax Write-Offs for Consultants

Home Office

100% deductible

The dedicated space where you take client calls, prepare deliverables, and run your consulting practice. The exclusive-use requirement is strictly enforced — the space cannot double as a guest bedroom.

Schedule C, Line 30

Business Travel (Flights & Hotels)

100% deductible

Flights, hotels, ground transportation, and lodging for client site visits, presentations, and industry conferences. The primary purpose of each trip must be business.

Schedule C, Line 24a

Client Meals (50%)

50% deductible

Meals with clients, prospects, and strategic partners where business is discussed. Only 50% is deductible under IRS rules. Document who attended and the business topic discussed.

Schedule C, Line 24b

Phone & Internet

100% deductible

Business-use percentage of your mobile phone and home internet. Consultants on client calls, video meetings, and remote work all day often justify 70–90% business use.

Schedule C, Line 25

Education & Conferences

100% deductible

Industry conference tickets, professional development courses, books, and certifications that maintain or improve your consulting expertise.

Schedule C, Line 18

Software Subscriptions

100% deductible

Zoom, Slack, Notion, project management tools, research databases, CRM software, and any SaaS product used to deliver consulting services.

Schedule C, Line 18

Common Mistakes to Avoid

Claiming 100% of business meals — the IRS limit is 50% regardless of how important the dinner was.
Extending client trips with personal vacation days and deducting the full cost — only the business days are deductible; personal days require you to prorate lodging costs.
Forgetting E&O (professional liability) insurance premiums — these are 100% deductible and often substantial.
Not deducting the self-employed health insurance premium on Schedule 1 — this above-the-line deduction can save thousands.

Recordkeeping Tips

Keep a client travel log noting the client name, business purpose, and dates for every trip — the IRS requires this documentation.
Write the attendee names and meeting topic on every restaurant receipt immediately after the meal.
Separate conference registration receipts from hotel and travel receipts — they go on different Schedule C lines.
Calendar-block every client meeting and business call so you have a contemporaneous record supporting home office and phone deductions.
