Key Takeaways:
1. Deducting expenses as a 1099 contractor or sole proprietor
- You don't need an LLC to deduct business expenses. A 1099 earner is automatically a sole proprietor and can deduct ordinary and necessary expenses against that income.
- Unreimbursed out-of-pocket costs tied to the work (seminars, training, travel) generally qualify.
- Keep a paper trail. A bank statement, Zelle/Venmo record, or credit card statement is usually enough, so you don't need the vendor to invoice you. Categorize each expense in QuickBooks or Excel (e.g., professional development, conference, travel).
- Deductions are limited to the income that activity produces.
- Once self-employed, you can also deduct accounting and legal fees (not possible as a W-2 employee), a home office, and a business share of your phone and internet.
- The School community has a Self-Employed Profit & Loss template that lists the deductible categories.
2. Business travel with a personal element
- Be conservative. If a trip mixes business and personal, allocate a percentage you're comfortable defending (e.g., 60-70%) rather than deducting 100%.
- For genuine business trips, document the agenda, meetings held, and purpose in case of an audit.
- If you have more than one business activity, allocate shared costs like a phone across them, but never claim more than 100% in total.
3. Short-term rental (STR) mileage
- Deductible miles include trips from your home office to the rental and to supply stores such as Home Depot.
- Tracking options, from strongest to weakest:
- A mileage app (MileIQ), though it can be tedious to mark non-business trips.
- A calendar or Excel log with date, purpose, and miles.
- An estimate (e.g., 40% of annual miles), which carries more audit risk.
- Mason's DIY approach: an iOS shortcut triggered by CarPlay that sends a Google Form feeding a spreadsheet, which makes logging opt-in instead of opt-out.
4. Bookkeeping software and shared expenses
- The CPAs advise against QuickBooks for most people, since clients often make a mess of it. They suggest REI Hub, Baselane, or Stessa. One attendee preferred REI Hub after duplicate-transaction problems with Stessa.
- Shared costs across two LLCs (e.g., a business phone line) can be split by a reasonable allocation, such as 50/50, and recorded in your bookkeeping.
- QUO (formerly OpenPhone) doesn't support two logins at once, and multi-number setups can cause texting glitches.
5. Home office deduction
- Simplified method: $5 per square foot, up to 300 sq ft (max $1,500). Only the office's square footage matters.
- Actual expense method: a percentage of utilities, taxes, and mortgage interest, but it triggers depreciation on your home. The CPAs generally advise against it unless the space is large, such as a garage.
- You'll provide office and total home square footage on your tax organizer.
6. Cost segregation and renovations
- Cost segregation studies need a breakdown of improvements, since different components fall into 5-, 7-, and 15-year classes.
- If a designer gives only a lump sum, ask for an itemized breakout, or at minimum break it into categories (furniture, paint, lighting, etc.).
- Preferred partners: CSSI (better for properties over roughly $750K) and RE Cost Seg.
- Wait until renovations are finished and the property is live, then do the study in one pass. The deadline isn't until tax time.
- 15-year property (landscaping, septic) can be bonus depreciated.
- A former primary residence converted to a rental can still qualify for bonus depreciation, and improvements made since purchase can be added to the basis. Don't double-count items already written off.
- A rented basement in your own home usually yields little because of its small size. You'd generally want a separate unit with its own bathroom and entrance.
7. Material participation hours
- Hours count from the time you're under contract. Qualifying activities include pre-service work, overseeing contractors, approving repairs, staging and decorating, HOA dealings, and bookkeeping.
- Travel to the property, research, and education don't count.
- Use the Sample Hours Tracker template on School and keep a rolling log as you go, not a reconstruction at year-end. Stick to its verbiage to stay audit-defensible.
8. Partnership LLC for a "board meeting" trip
- A partnership return costs more and adds complexity, and the trip must be a genuine business expense.
- The math: tax savings = expense x your tax bracket. A $4,000 trip saves about $960 at 24% or about $1,480 at 37%. Compare that to the extra cost of the return (the attendee quoted about $570), and weigh whether you'll repeat the trip every year.
- Most people use a single-member LLC for simpler compliance.
- In community property states (AZ, CA, ID, LA, NV, NM, TX, WA, WI), spouses can skip the partnership return for a spousal LLC. Florida, Ohio, and New York aren't on that list.
9. Logistics and deadlines
- The extension deadline is Thursday, Oct 15, and the team is working through the weekend.
- Upload draft returns to TaxDome and message the team for review. Kevin said he would flag one attendee's draft with the team.
- Year-end planning calls should start in November.
General Mindset
- Documentation is your defense. The system runs on honor, but you have to be able to back it up. Keep records consistently and as you go.
- Deduct what's ordinary, necessary, and genuinely business. Be honest about personal use and allocate conservatively.
- Do the math before the strategy. A deduction only saves your bracket percentage of the spend, so don't spend money just to save tax.
- Weigh complexity and time, not just dollars. Simpler structures often win.
- Plan early. Set up tracking, bookkeeping, and cost seg conversations before you need them, and plan year-end moves in November.
- Use your CPA as a partner. Verify drafts, ask questions, and raise concerns before deadlines.
