  Schedule C When a Freelancer Dies: Final Return, IRD, and What Happens to the Business (2026)

  If a self-employed taxpayer dies mid-year, income already received goes on their final Schedule C — but unpaid invoices become Income in Respect of a Decedent, taxed to whoever collects them and, unlike the decedent's own business income, exempt from self-employment tax. A 2026 guide to splitting the year correctly, what happens to depreciated equipment and any leftover NOL, and when Form 1310 is required.

  The Claim of Right Doctrine: What to Do When You Have to Repay Income You Already Paid Tax On (2026)

  A chargeback, a clawed-back bonus, a retainer refund after the books closed — if you repay business income you already reported and paid tax on in a prior year, Section 1341 lets you choose the better of two ways to get that tax back. A 2026 guide to the $3,000 threshold, the two computation methods, and a worked example showing when each one wins.

  Self-Employment Tax When You Also Have a W-2 Job: The Combined Social Security Wage Base Explained (2026)

  If you freelance on the side of a W-2 job, your self-employment tax is almost never the full 15.3% everyone quotes. Schedule SE Part I, lines 8a through 9, reduces or eliminates the 12.4% Social Security portion once your W-2 wages already reach the year's wage base — $184,500 for 2026. A 2026 walkthrough of the exact Schedule SE mechanics, a worked example showing the real savings, and the Medicare portion that never goes away.

  Farrier Tax Deductions: The Complete 2026 Schedule C Guide for Equine Hoof Care Professionals

  Tax deductions for self-employed farriers: how a specially-built truck rig can be fully expensed in year one thanks to 100% bonus depreciation, why the $32,000 'heavy SUV' cap almost never actually limits you, AFA certification vs. farrier-school tuition, and why most farrier income has no 1099 paper trail at all.

  Dog Groomer Tax Deductions: The Complete 2026 Schedule C Guide for Mobile and In-Salon Groomers

  Every write-off a self-employed dog groomer — mobile, in-home, or salon-chair-rental — can claim for 2026, mapped to the right Schedule C line: clippers, dryers, and grooming tables under Section 179 or the de minimis safe harbor on Line 13; shampoo and grooming supplies on Line 22; the mobile grooming van at $0.725/$0.76 per mile or actual expenses on Line 9; bite, scratch, and care-custody-control liability coverage on Line 15; booth or chair rent on Line 20b; state sales tax on retail product sales; and why grooming isn't an SSTB for the QBI deduction.

  Medical Biller and Coder Tax Deductions: The Complete Schedule C Guide (2026)

  Independent medical billers and coders work almost entirely from a home office with no vehicle and no physical inventory — which means the deductions that matter are credentialing, continuing education, software, and insurance, not the categories most Schedule C guides lead with. A 2026 guide covering which certification costs are deductible and which aren't under the new-trade-or-business rule, CEU requirements, encoder and practice-management software, E&O and cyber liability coverage, HIPAA-compliant tooling, and the home-office deduction for a desk-only business.

Side-by-side comparisons of CentSense vs. FreshBooks, Wave, Expensify, and other tools for 1099 workers.

  COBRA vs. ACA Marketplace for Freelancers (2026): The 60-Day Decision After You Leave Your Job

  A freelancer who just left a W-2 job gets one 60-day window to choose between COBRA continuation coverage and an ACA Marketplace plan — and once you elect COBRA, dropping it early doesn't reopen the Marketplace door. A 2026 guide to cost, the self-employed health insurance deduction, Premium Tax Credit eligibility, and the 400%-of-poverty-line subsidy cliff that's back after the enhanced ACA subsidies expired.

  HSA vs FSA for the Self-Employed: Why It's Usually Not a Choice at All (2026)

  HSA vs FSA looks like a side-by-side comparison until you check the eligibility rule most freelancers never see coming: self-employed persons — sole proprietors, single-member LLC owners, and more-than-2% S-corp shareholders alike — cannot have an FSA at all under IRS Publication 969. A 2026 guide to why that's true, when a freelancer can still access one (a spouse's employer plan, or through their own employees), and how HSA eligibility works instead.

  Your Joint Refund Went to Your Spouse's Student Loan: Injured Spouse (Form 8379) vs Innocent Spouse (§6015 / Form 8857) in 2026

  Two remedies, near-identical names, opposite directions. Injured spouse relief protects YOUR share of a refund from THEIR separate debt — it relieves no tax at all. Innocent spouse relief under §6015 relieves YOU of liability for THEIR tax problem — and hands the whole bill to them. A 2026 guide for freelancers who already filed jointly: the three doors of §6015(b), (c) and (f), why only (f) reaches an underpayment, the 2-year clock that a joint refund offset does not start, why a §6015(c) election can never produce a refund, and how self-employment tax is allocated separately under §6015(d)(2).

  "No Tax on Tips" for Self-Employed Freelancers: The Section 224 Deduction Explained (2026)

  IRC Section 224 lets self-employed workers in roughly 70 qualifying occupations deduct up to $25,000 of cash tips through 2028 — but it never reduces self-employment tax, and a thin-margin freelance business can cap the deduction below the tips actually received. A 2026 guide to the cap, the MAGI phase-out, and the net-income limitation that trips up gig workers.

  The R&D Tax Credit for Freelancers: How a Solo Developer or Consultant Can Claim It — and Even Use It Against Payroll Tax (2026)

  The Section 41 research credit isn't just for corporations with R&D departments. A freelance software developer, product-building consultant, or solopreneur with qualifying research expenses can claim it on Form 6765 — and if the business is new and small enough, apply up to $500,000 of it against payroll tax instead of income tax. A 2026 guide to the four-part test, what counts as qualified research expenses for a one-person business, the payroll tax election, and how the 2025 One Big Beautiful Bill Act's new immediate-expensing rule for research costs changes the math.

  Section 1244 Stock: Turning a Failed S-Corp or C-Corp Investment Into an Ordinary Loss (2026)

  If you elected S-corp status and put your own cash into the company as capital, and the business later fails, that loss is normally a capital loss capped at $3,000 a year against ordinary income — decades to fully use. Section 1244 stock changes that: up to $50,000 (single) or $100,000 (joint) of the same loss becomes fully deductible ordinary loss in the year it happens. A 2026 guide to what qualifies as §1244 stock, the $1,000,000 capitalization limit, who can claim it, and a worked example comparing the two paths side by side.

  Your Order History Isn't a Tax Record: The IRS Rule on Retailer-Hosted Receipts (2026)

  Costco, Best Buy, Home Depot, and self-checkout kiosks let you skip the paper receipt and "just look it up later" — but under Revenue Procedure 97-22, using a retailer's own account system doesn't relieve you of your own recordkeeping duty, and most retailers don't keep purchase history nearly as long as the IRS can ask about it. A 2026 guide to why the app isn't your archive, and what to do instead.

  The Weekend Sandwich Rule: When a Non-Working Day Still Counts as a Business Travel Day (2026)

  A Friday meeting and a Monday meeting in the same out-of-town trip — does the weekend in between count as personal, killing part of your travel deduction? IRS Publication 463 has a specific rule for this: weekends, holidays, and other necessary standby days sandwiched between two business days count as business days too. A 2026 guide to the sandwich rule, how it differs from tacking a weekend onto the end of a trip, and what records prove it.

  No Receipt Arrives for Your Recurring Software Charges — Here's What the IRS Actually Requires (2026)

  Your annual SaaS renewal auto-charges a card on file and no invoice ever hits your inbox; eleven months out of twelve, the only trace is a cryptic line on a bank statement. Freelancers assume that's a documentation gap, but §274(d)'s strict receipt-and-log rule doesn't even apply to ordinary software and supplies — it's limited to travel, meals, gifts, and listed property. A 2026 guide to what §6001 and Treas. Reg. §1.6001-1(e) actually require for a recurring, receiptless charge, and the two-document habit that closes the gap in five minutes a year.
