Attending conventions and seminars can be a valuable way to grow your business, learn new skills, and connect with industry peers. But not every “business-related” event is automatically deductible.
The IRS has specific rules depending on:
Where the event is held (North America, foreign countries, or cruise ships)
How expenses are documented
Whether the event meets the ordinary and necessary test for your trade or business
This guide explains how to determine if your convention or seminar qualifies for a tax deduction, what costs are deductible, and how to meet IRS documentation requirements.
1. Three IRS Categories for Conventions and Seminars
A. North American Conventions
Examples: U.S., Puerto Rico, Canada, Mexico, and certain treaty countries in the Caribbean.
Deductibility: Generally deductible if attendance benefits your trade or business and meets the ordinary and necessary expense rule.
B. Foreign Conventions
Definition: Held outside the North American area.
Requirements:
Must directly relate to your trade or business.
Must be as reasonable to hold abroad as in North America.
Often requires an international audience and a strong business justification.
Documentation: Written statement explaining why the foreign location was necessary, plus supporting evidence.
C. Cruise Ship Conventions
Special limitations:
The ship must be U.S.-flagged.
All ports of call must be in the U.S. or U.S. territories.
Deduction is capped at $2,000 per year.
You and the organizer must provide attendance statements with your tax return.
2. IRS Rules for Deducting Convention and Seminar Expenses (2025 Tax Year)
The IRS outlines clear requirements for claiming these deductions. Publication 463 is your go-to reference.
General Rules
Ordinary and Necessary: Must be common and accepted in your trade or business, and helpful for your business activities.
Business Purpose: You must be able to show a direct connection between the event and your business.
No Lavish Spending: Expenses considered extravagant are not deductible.
North American Conventions
Covered areas include the U.S., U.S. territories, Canada, Mexico, and certain Caribbean nations under specific treaties.
If the event is in this area and meets the general rules, there are no extra limitations.
Foreign Conventions
You must prove the foreign location was as reasonable as a North American location.
Include details like attendee locations, the purpose of the event, and resource availability.
Provide a written statement and supporting evidence with your records.
Cruise Ship Conventions
Must be on a U.S.-registered ship with stops only in the U.S. or U.S. territories.
Submit a written statement detailing:
Total days of the trip
Hours spent on business activities
The program of events
Annual deduction limit: $2,000.
3. Documentation Requirements
Regardless of business structure:
Sole Proprietors: Deduct directly on your Schedule C.
Corporations: Pay through the corporate account or reimburse through an expense report. Keep all documentation in corporate records.
You should keep:
Receipts, invoices, and canceled checks.
Written statements for foreign and cruise conventions.
Proof of attendance (registration confirmation, name badge, agenda).
4. Deductible Costs
You can deduct:
Event fees
Travel (airfare, train, bus, car) between home and the event location
Lodging and meals (meals limited to 50%)
Transportation at destination (taxis, rideshare, rental cars)
Shipping of materials or display items
Tips related to these expenses
Tip: For foreign and cruise ship events, maintain extra documentation to avoid challenges from the IRS.

Bottom Line
Attending conventions and seminars can be an excellent investment in your business, but deductions depend on meeting IRS location rules, maintaining thorough records, and ensuring the event meets the ordinary and necessary standard.
With careful planning, you can maximize your deductions and stay compliant.
