Professional Organizer Bookkeeping: Package Pricing, Client Property Liability, and Why the Donation Deduction Isn't Yours
A bookkeeping guide for professional organizers covering how to book package deposits and maintenance retainers as unearned revenue, the insurance clients expect (general liability, E&O, workers' comp — roughly $1,500–$3,000/year), why the Goodwill donation deduction belongs to the client rather than the organizer, and when a day helper must be classified W-2 instead of 1099.
RV Rental Bookkeeping: Why the IRS May Tax Your Motorhome Like a Vacation Home
Section 280A can classify a rented RV as a dwelling unit, capping deductions once personal use exceeds 14 days or 10% of rental days. How peer-to-peer RV hosts should keep a use-day log, choose between 5-, 7-, and 27.5-year depreciation, apply 100% bonus depreciation or Section 179, and record platform commissions gross instead of net.
No Mileage Log, No Deduction: What Simmons v. Commissioner Teaches About Vehicle Expense Substantiation
In Simmons v. Commissioner (T.C. Memo. 2026-34), the Tax Court disallowed a $12,939 vehicle deduction because QuickBooks entries and lease agreements failed the four-element substantiation test of IRC Section 274(d) — amount, time, place, and business purpose. Here's what a mileage log must contain, why the Cohan estimation rule can't save you, and how the same entity-level documentation gap cost the taxpayer interest and utility deductions plus a 20% negligence penalty.
Solar Panel Cleaning Business Bookkeeping: Turning Soiling-Loss Data Into a Recurring-Contract Pricing Model
NREL data puts solar soiling losses at ~5% of output nationally and 25%+ in dusty climates — the basis for pricing 2–4 cleanings a year. How solar panel cleaning operators should book prepaid annual contracts as deferred revenue, track fuel and water per job to capture 15–25% route-density gains, and record DI systems and fall-protection gear as Section 179-eligible assets.
Substack and Newsletter Writer Taxes: Schedule C, the Hobby-Loss Trap, and What You Can Deduct
Paid newsletter revenue on Substack, Ghost, or beehiiv is Schedule C self-employment income — owing 15.3% SE tax, quarterly estimates once you owe over $1,000, and facing a new 90% cap on hobby-expense deductions in 2026. Here's how the 1099-K thresholds, the 13–19% effective platform-fee cost, and the deduction rules actually work for writers.
One Missing Sentence Cost a Donor a $4.4 Million Charitable Deduction — What Wells v. Commissioner Requires of Your Acknowledgment Letter
In Wells v. Commissioner (2026), the Tax Court disallowed a $4.42 million charitable deduction for donated real estate because the charity's acknowledgment letter was undated and never stated whether the donors received goods or services in return — Section 170(f)(8) demands strict, not substantial, compliance. The 20% accuracy penalty was abated only because the donors documented good-faith reliance on their CPA.
Eyelash Extension Studio Bookkeeping: The Supply, Retail, and Depreciation Lines Most Lash Artists Get Wrong
A lash studio's costs don't fit one "supplies" line — service consumables, retail inventory, and depreciable equipment like lash beds and LED lamps each need their own account. This guide covers a six-category chart of accounts, the Section 179 deduction most lash artists miss, quarterly retail inventory counts, and booth-renter vs. employee classification.
Freelance Personal Stylist and Wardrobe Consultant Taxes: A Bookkeeping Guide
Client wardrobe advances are pass-through funds, not revenue — the bookkeeping distinction that determines whether a freelance stylist's books reconcile. Covers Schedule C, why work clothing is almost never deductible, the home-office exclusivity test, sales tax on markup resale, 1099-NEC vs 1099-K, and a minimal chart of accounts.
Buying Machinery at Auction: Cost Basis, Use Tax, and 100% Bonus Depreciation
A $150,000 CNC lathe bought at auction and fully expensed under 100% bonus depreciation can generate roughly $37,500 in first-year tax savings at a 25% effective tax rate, but only if the buyer's premium, sales/use tax, and rigging costs are correctly capitalized into cost basis first.
Drone Photography and Aerial Inspection Bookkeeping: Tracking FAA Costs, Equipment Depreciation, and Per-Flight Job Profit
Commercial drone operators should separate FAA licensing costs, individually tracked aircraft depreciation, and per-job variable costs into distinct accounts, since a $200 real estate listing shoot and a $3,000 utility inspection job carry entirely different insurance, crew, and processing costs per flight hour.
Bookkeeping for Hotshot Trucking: Cash Flow, IFTA, and Tax Deductions Explained
Hotshot trucking operators need a chart of accounts that separates fuel, MC-authority insurance, factoring fees, and IFTA liability from generic vehicle expenses, since brokers often pay 15-45 days after delivery while fuel and insurance are due immediately.
Marine Surveyor Bookkeeping: Certification Dues Are Overhead, Not Startup Costs
Marine surveyors often file NAMS or SAMS certification dues and continuing education costs as startup expenses, but the IRS treats recurring dues, CE tuition, and E&O insurance premiums as ordinary business expenses deductible in the year paid, not amortized over 180 months.
