Year-End Tax Moves for 1099 Independent Adjusters (Tax Year 2026)
The short version: Tax year 2026 changed more than usual for 1099 independent adjusters. The IRS raised the business mileage rate in the middle of the year. The 1099-NEC reporting threshold jumped from $600 to $2,000. The 2025 tax law (the One Big Beautiful Bill Act, which the IRS now also calls the "Working Families Tax Cuts") locked in 100% bonus depreciation and changed the QBI deduction. And if a late-season deployment such as Hurricane Isaias put an unexpected check in your account this fall, your fourth-quarter estimate probably needs a second look.
Here is what changed, what it means for an IA's return, and what to handle before December 31 and January 15.
General information, not tax advice. Figures below come from IRS publications current as of late October 2026. Your situation (filing status, entity type, state, other income) changes the answer. Confirm every move with a CPA or enrolled agent before you act.
1. Split your 2026 mileage log at July 1
The IRS set the 2026 business standard mileage rate at 72.5 cents per mile in Notice 2026-10. Then, citing higher fuel prices, it issued Announcement 2026-11 in July, which raised the business rate to 76 cents per mile for expenses paid or incurred on or after July 1, 2026. Miles driven before July 1 stay at 72.5 cents.
What it means for you: You need two totals this year, not one. If your log lives in an app, run a report for January 1 through June 30 and another for July 1 through December 31. If it lives in a notebook on the dash, now is a good time to add a line under June.
Quick illustration (our math, not an IRS example): 20,000 business miles split evenly works out to 10,000 × $0.725 plus 10,000 × $0.76, or $14,850. Lump everything at the lower rate and you leave $350 of deduction on the table. Lump it all at the higher rate and you have a number you can't support.
One trade-off to remember: if you use the standard mileage rate for a vehicle, the rate already includes an allowance for depreciation. You generally can't also write off that same vehicle with Section 179 or bonus depreciation. Pick the method with your tax pro, and keep the log either way.
2. Re-run your Q4 estimate before January 15, 2027
The fourth estimated payment for tax year 2026 (covering September 1 through December 31) is due January 15, 2027, per the IRS estimated tax FAQ. You generally have to make estimated payments if you expect to owe at least $1,000 after withholding and credits.
The IRS safe harbor helps you avoid an underpayment penalty if your payments cover the smaller of:
- 90% of your 2026 tax, or
- 100% of your 2025 tax, or 110% if your 2025 adjusted gross income was over $150,000 ($75,000 if married filing separately).
What it means for you: CAT income is lumpy, and 2026 was lumpier than most. The Atlantic season was historically quiet until Isaias made landfall near Destin, Florida on October 9 (we broke down the claim numbers in Hurricane Isaias by the numbers). If you were cruising on the prior-year safe harbor all year, you may be fine. If you were paying based on a slow first half and then billed a heavy October and November, run the numbers again before you mail that January payment.
3. Buy and place equipment in service by December 31 (if you need it)
Two depreciation rules matter for gear purchases this year:
- Bonus depreciation: The 2025 law made 100% bonus depreciation permanent for qualified property acquired after January 19, 2025, according to the IRS summary of the law's business provisions.
- Section 179: For tax years beginning in 2026, Rev. Proc. 2025-32 sets the expensing limit at $2,560,000, phasing out once qualifying purchases pass $4,090,000. The separate cap for certain heavy SUVs is $32,000.
What it means for you: No IA is bumping into a $2.56 million ceiling. The practical point is that most business equipment you buy and put into service by December 31 can generally be deducted in full this year instead of over several years. For an adjuster that may include a laptop, tablet, drone, ladder, measuring tools and similar field gear.
The key words are "placed in service." A tablet still in the box on New Year's Eve doesn't count for 2026.
Two cautions:
- Vehicles have their own caps and business-use rules. We are not quoting the 2026 passenger-auto depreciation limits here because we could not confirm them on irs.gov at press time. Get those numbers from your tax pro before you buy a truck for the deduction.
- A deduction is not free money. Spending $1,000 to save a few hundred in tax only makes sense if you needed the $1,000 item anyway.
4. Check how the QBI deduction applies to you now
The qualified business income (QBI) deduction under Section 199A lets many sole proprietors deduct up to 20% of qualified business income. The 2025 law removed its scheduled expiration and added a new floor starting with tax years beginning after 2025:
- A minimum deduction of $400 for taxpayers with at least $1,000 of QBI from an active trade or business (one you materially participate in), per Rev. Proc. 2025-32 and the IRS QBI deduction page.
- 2026 income thresholds, above which extra limits start to phase in: $201,750 for most filers and $403,500 for married filing jointly. The phase-in ranges end at $276,750 and $553,500.
What it means for you: A working IA who runs their own files is the textbook "active" business owner, so the minimum deduction should matter mostly in a thin year. If your income lands near the thresholds, ask your preparer how retirement contributions (next section) could pull taxable income back under them. Whether adjusting counts as a "specified service" business is a question for your preparer, too.
5. Decide on a SEP-IRA or Solo 401(k)
The 2026 retirement limits from the IRS:
| Item | 2026 limit |
|---|---|
| SEP-IRA contribution | Lesser of 25% of compensation or $72,000 |
| 401(k) employee deferral | $24,500 |
| Catch-up, age 50+ | $8,000 (ages 60–63: $11,250 instead) |
| Traditional/Roth IRA | $7,500 (plus $1,100 catch-up at 50+) |
Two things self-employed adjusters often miss:
- "Compensation" isn't your gross. For a sole proprietor, the SEP math starts from net self-employment earnings after the deduction for half of self-employment tax and your own contribution. The IRS worksheets in Publication 560 bring the effective rate to roughly 20% of net earnings, not 25%.
- Timing differs by plan. The IRS says you can establish and fund a SEP as late as your return due date, including extensions. That makes the SEP a good fallback for April. A Solo 401(k) can allow more total contributions at lower income because of the employee deferral, but its setup and deferral deadlines work differently. Talk to your plan provider before December 31 rather than assuming you can open one in March.
6. Claim self-employed health insurance on the right line
If you pay your own medical, dental or qualified long-term-care premiums, the self-employed health insurance deduction is an adjustment to income, not an itemized deduction. According to IRS Tax Topic 502, it can cover you, your spouse, your dependents and a child under 27 at year-end. You need a net profit from the business, and the deduction is figured on Form 7206.
What it means for you: If a spouse's employer plan was available to you for part of the year, read the Form 7206 instructions on how that affects which months qualify. That detail trips up a lot of mixed-income households.
7. Expect fewer 1099-NECs, and owe the same tax
Starting with payments made in 2026, the IRS instructions for Forms 1099-MISC and 1099-NEC raise the nonemployee compensation reporting threshold from $600 to $2,000. Forms are due to recipients and the IRS by January 31, 2027.
What it means for you, two ways:
- As a payee: A small firm or one-off client who paid you $1,800 no longer has to send a form. That income is still taxable. Reconcile your own invoices and bank deposits instead of building your return from the 1099 stack.
- As a payer: If you hire ladder assists or field help, you now issue a 1099-NEC only to people you paid $2,000 or more. Keep W-9s on file for everyone anyway; it costs nothing and saves a scramble later.
Year-end checklist for 1099 adjusters
| Task | Deadline |
|---|---|
| Split mileage log into Jan–Jun and Jul–Dec totals | Before you file |
| Buy and place needed equipment in service | December 31, 2026 |
| Talk to a provider about Solo 401(k) setup | Before December 31, 2026 |
| Recalculate and pay Q4 estimated tax | January 15, 2027 |
| Send 1099-NECs to helpers paid $2,000+ | January 31, 2027 |
| Open and fund a SEP-IRA (if you choose one) | Your return due date, including extensions |
What to watch
- The 2027 mileage rate. The IRS usually announces next year's rate in December. Don't assume 76 cents carries over.
- Inflation indexing. The $2,000 1099-NEC threshold may be adjusted for inflation starting in 2027, and the $400 QBI minimum is indexed for tax years after 2026.
