Can I claim a tax deduction for attending an engineering conference?
I'm planning to attend a week-long engineering conference this summer that'll set me back around $4,000. I'm trying to figure out the best way to handle this for tax purposes. My situation is a bit unique - I run my own engineering consultancy but I'm also employed as a W-2 engineer at a separate company. I'm wondering what the smartest approach would be for deducting these conference expenses. Should I claim it as a business expense for my own engineering firm or would it be better to claim it as an unreimbursed business expense for my W-2 position? The conference is definitely relevant to both aspects of my work. Any advice on the best way to handle this for tax purposes would be greatly appreciated!

The best approach would be to claim the conference as a business expense for your engineering firm rather than as an unreimbursed business expense for your W-2 job. Since the Tax Cuts and Jobs Act went into effect, most unreimbursed employee business expenses can no longer be deducted on individual returns. As a business owner, you can deduct legitimate business expenses like conference attendance on your Schedule C, which will reduce your self-employment income. Make sure the conference is relevant to your business operations and keep documentation of all expenses (registration, travel, lodging, meals, etc.). Remember that meals during the conference are typically 50% deductible. Just be prepared to demonstrate that attending the conference has a legitimate business purpose related to your engineering firm if the IRS ever questions it.

•What if the conference is more relevant to my W-2 position than my own business? Does that matter for deduction purposes? And do I need to get any specific documentation beyond receipts?

•The relevance to your W-2 position versus your business doesn't matter for deduction purposes - what matters is that you can show a legitimate business purpose for your engineering firm. If the knowledge gained helps maintain or improve skills needed in your business, that's sufficient justification. Beyond receipts, keep the conference agenda/program showing the educational content, notes you took during sessions, and any business cards from networking. Also document how the conference content relates to your engineering business - this creates a stronger case for the deduction if ever questioned.

I was in a similar situation last year with deducting professional development costs. I found this awesome tool called https://taxr.ai that really helped me sort out what was deductible for my business vs what wasn't. It analyzed all my receipts and conference materials and gave me a detailed breakdown of exactly what I could claim on my Schedule C. Saved me hours of research and probably avoided an audit!

•Does it actually tell you which specific expenses are deductible? Like if I spend money on extending my stay a few days for sightseeing, will it flag that as non-deductible?

•Sounds interesting, but I'm skeptical about these AI tax tools. How accurate is it compared to just asking my accountant? I worry about software missing nuances that a human professional would catch.

•It does flag specific expenses as potentially non-deductible. In my case, it correctly identified that my extra two days of hotel and meals after the conference weren't business-related and should be separated out as personal expenses. It even suggested how to properly allocate partial expenses. Regarding accuracy versus an accountant, I actually had my accountant review what taxr.ai suggested, and she was impressed with the recommendations. She said it caught all the same things she would have, but saved her time on analysis. It's not replacing professional advice, but it helps organize everything before you see a tax professional.

Just wanted to follow up about that taxr.ai recommendation - I decided to give it a try for my situation with my photography business and conference expenses. I was really surprised by how detailed it was! It identified which parts of my trip were clearly business vs personal, created a full documentation package for my records, and even found some deductions I would have missed (like certain business networking events that I didn't realize qualified). My tax prep feels much more organized now. Definitely worth checking out for anyone with a small business trying to correctly deduct professional development costs.

Another thing to keep in mind - if you're struggling to get answers from the IRS about business expense deductions, I used https://claimyr.com to get through to an actual IRS agent after weeks of unsuccessful attempts. You can see how it works here: https://youtu.be/_kiP6q8DX5c. Totally worth it for getting a definitive answer on some questionable business deductions I had. The agent confirmed which specific conference expenses were allowable and which weren't.

•How does this actually work? Do they have some special connection to the IRS or something? I've been trying to get through to ask about some home office deductions for weeks.

•Yeah right, nothing can get you through to the IRS faster. I've been trying for months about a mistake they made on my return. This sounds like a scam to take advantage of desperate taxpayers.

•They use a technology that navigates the IRS phone tree and waits on hold for you. When an actual agent picks up, you get a call connecting you directly to that agent. No special connection - they're just using tech to handle the painful waiting process so you don't have to sit on hold for hours. I was skeptical too initially. What convinced me was that you only pay if they actually get you through to an agent. I spent weeks trying to get clarification on business deductions for my situation and was getting nowhere. Within 2 hours of using their service, I was talking to someone who could actually help.

Well I have to eat my words. After my skeptical comment I figured what the hell and tried Claimyr since nothing else was working. Within 90 minutes I got a call connecting me to an actual IRS agent! I explained my situation about the error on my return and got it resolved in one call. Saved me hours of frustration and probably weeks of waiting. Can't believe something actually worked after all my failed attempts.

Something else to consider - I'd recommend taking a close look at the conference agenda and breaking down expenses according to educational vs. entertainment components. Some conferences pad their schedules with social activities that aren't deductible. My accountant had me allocate my registration fee based on the percentage of time spent in actual educational sessions vs. networking events.

•Does this apply to meals too? Like if there's a dinner with a keynote speaker, is that educational or entertainment? It's really hard to figure out where to draw the line.

•For meals with educational content like a keynote speaker, those would typically qualify as business meals (50% deductible) as long as business is conducted or discussed. The key is the primary purpose of the meal. For the registration fee allocation, you'd look at the agenda and calculate roughly what percentage of the conference time is spent on legitimate educational activities versus purely social events. For example, if there's a 4-day conference but one full day is just a golf tournament, you might reasonably allocate 75% of the registration as educational and 25% as entertainment.

Don't forget about state tax implications too! I deducted a conference on my federal return correctly but didn't realize my state had different rules about business expense deductions. Ended up having to file an amended state return.

•Which state was this? I'm in California and wondering if I need to worry about this for a conference I attended in Las Vegas.

•This happened to me in New York - they don't automatically follow federal business expense deductions and have their own rules about what qualifies. California generally conforms to federal rules for business expenses, but you should double-check since some states like New York, Pennsylvania, and others have their own criteria. The conference location doesn't matter as much as your state of residence and where your business is registered.
