Picture two couples, both 60 years old, both retired early, both buying health insurance on the marketplace in the same county.

Couple one reports 84,500 dollars of income for 2026. Couple two reports 84,601.

Assume the benchmark silver plan for two 60-year-olds in that county runs about 27,600 dollars a year, which is realistic in plenty of places. Couple one gets roughly 19,000 dollars of help paying their premiums this year. Couple two gets zero. Not a little less. Zero. And starting this year, if couple two collected that help in advance every month and ends up over the line when they file, they pay back every single dollar. There's no cap anymore.

One hundred and one dollars of income. Nineteen thousand dollars of consequence. That's an effective marginal tax rate that would make a hedge fund manager weep.

It's called the subsidy cliff, and it's back. Open enrollment for 2027 coverage starts November 1st. Insurers have requested a median premium increase of about 15 percent for next year. And the 2026 income that determines whether you owe money back is still being written, right now, over the next 94 days.

If you're self-employed, retired early, running a small business, or married to someone who is, this is the most expensive number in your financial life that you've probably never calculated. So let's calculate it. Then let's build the system that keeps you on the right side of it.

Standard disclaimer, and I mean it: I'm not a tax advisor or an insurance broker. What follows is how the rules work and how I'd think about them. Run your own numbers past a CPA and a licensed broker before you act.

What changed, in plain English

From 2021 through 2025, the enhanced premium tax credits smoothed everything out. Above four times the federal poverty level, your subsidy just tapered off gradually. Earn a little more, get a little less help. No cliff.

Those enhanced credits expired at the end of 2025 and haven't been restored. So 2026 coverage went back to the original rules. Premium tax credits exist between 100 and 400 percent of the poverty line. Above 400 percent, nothing.

Then the tax bill signed last summer added a second punch. Before 2026, if you took too much advance credit and had to repay the difference at tax time, the repayment was capped for most incomes below 400 percent. Starting with the 2026 tax year, those caps are gone. Whatever excess you received, you repay in full.

Put those two together and you get a very specific danger. You estimated your income last fall, the marketplace sent your insurer a subsidy every month based on that estimate, and if your actual 2026 income lands above the line, the whole year's subsidy comes due with your tax return next April.

The two clocks you're on right now

This is where people get confused, so let's slow down.

Clock one is 2026. Your 2026 coverage subsidy is based on your 2026 income, measured against last year's poverty guidelines. The 400 percent line for 2026 coverage is 62,600 dollars for a single person, 84,600 for a household of two, and 128,600 for a household of four. You've already received nine months of advance credits against that. You have until December 31st to control where your 2026 income finally lands.

Clock two is 2027. When you enroll starting November 1st, you'll estimate your 2027 income, measured against the 2026 poverty guidelines. The line for 2027 coverage is 63,840 dollars for a single person and 132,000 for a family of four. In most states, open enrollment runs through January 15th, but December 15th is the date that matters if you want coverage starting January 1st.

Clock one is a cleanup job. Clock two is a design job. Most people only think about the second one, and the first one is where the money's actually at risk this quarter.

Know which number they're actually measuring

The marketplace doesn't care about your gross revenue, your take-home pay, or what your bank account says. It uses a specific version of modified adjusted gross income.

Start with your adjusted gross income, the number at the bottom of the first page of your 1040. Then add back three things: tax-exempt interest, the portion of Social Security benefits that isn't taxable, and any foreign earned income you excluded.

That first add-back catches people. Municipal bond interest is tax-free on your return, but it counts in full toward the cliff. The early retiree who shifted a pile of money into munis to "keep income low" didn't keep anything low for this purpose.

And a few things push the number up that people forget are income at all. A Roth conversion. A big capital gain from rebalancing. A required distribution from an inherited IRA. A one-time bonus from a consulting project. Any of those can walk you straight off the edge in a single transaction.

The levers, ranked by what they cost you

Here's the good news. The same MAGI that can push you over the cliff can be legitimately pulled back under it. Some levers cost you nothing but a decision. Others have real tradeoffs. I'll rank them in the order I'd reach for them.

Lever 1: Pre-tax retirement contributions

This is the workhorse. Every dollar that goes into a traditional 401(k), solo 401(k), SEP-IRA, or deductible traditional IRA comes straight off your AGI.

For 2026, the employee deferral limit in a 401(k) is 24,500 dollars, plus an 8,000 dollar catch-up if you're 50 or older, or 11,250 if you're between 60 and 63. Self-employed people can add an employer profit-sharing contribution on top of that, generally around 20 percent of net self-employment earnings.

For a self-employed person with room to save, this lever alone can move MAGI by 30,000 or 40,000 dollars. The key detail for 2026: if you want to make employee deferrals into a solo 401(k), get the plan established and your election documented before December 31st. Don't wait for April.

Lever 2: The health savings account

Here's a quiet change most people missed. Starting in 2026, every bronze and catastrophic plan on the marketplace counts as HSA-eligible. If you're on one of those plans, you can contribute up to 4,400 dollars for self-only coverage or 8,750 for family coverage in 2026, plus 1,000 if you're 55 or older.

Every dollar reduces your MAGI. And unlike most levers, you can fund it for 2026 all the way until your tax filing deadline next April. That makes it the perfect last-mile tool: once you know exactly how far over the line you are, the HSA closes the final gap.

Lever 3: The self-employed health insurance deduction

If you're self-employed and paying your own premiums, those premiums are deductible above the line, which reduces AGI. The complication is that the deduction and the premium tax credit depend on each other. The deduction is based on what you paid after the credit, and the credit is based on income after the deduction. It's circular, and the IRS has an approved calculation method to resolve it. Good tax software handles it. Just make sure your preparer is actually running it and not taking the easy approximation.

Lever 4: Timing, if you're on a cash basis

A cash-basis business recognizes income when it's received and expenses when they're paid. That gives you legitimate control over the edges of the year.

An invoice sent December 28th with net 30 terms lands in January. A software renewal or supply order paid December 15th counts this year. And equipment you actually need, bought and placed in service before year end, can be fully expensed under the bonus depreciation rules that came back last year.

The emphasis is on actually need. Buying a 40,000 dollar truck to save a 19,000 dollar subsidy only makes sense if you were going to buy the truck. Don't let the tail wag the dog.

Lever 5: Capital gains discipline

If you're near the line, the rebalance can wait until January. A gain realized January 2nd is a 2027 problem, and you'll plan for it in your 2027 projection.

Meanwhile, if you have losses sitting in a taxable account, harvesting them now offsets gains dollar for dollar and can knock up to 3,000 dollars off ordinary income on top of that.

Lever 6: Don't add fuel

This isn't a lever so much as a list of things not to do in Q4 if you're within striking distance. Don't do a Roth conversion without running the cliff math first. Don't take a discretionary IRA distribution. Don't sell the rental property in December. Every one of those can still be the right move. Just make it on purpose, with the subsidy cost on the same spreadsheet as the tax cost.

One warning about going too low

In states that didn't expand Medicaid, including Texas, where I live, and Florida, income below 100 percent of the poverty line doesn't get you marketplace subsidies or Medicaid. You fall into a gap with nothing.

So the target isn't "as low as possible." The target is a band. For most people it's somewhere between comfortably above 100 percent and safely below 400 percent. Aim for the middle of the band, not the edge.

When you can't get under: stop the bleeding

Some of you will run the math this weekend and realize 2026 is going over no matter what. Maybe a client paid a big invoice early. Maybe you sold a business. It happens.

If that's you, the move is to update your marketplace application with your new projected income now. That reduces or stops the advance credit for the remaining months of the year, which shrinks what you'll owe back in April. Three months of stopped subsidies beats three more months of stacking a bill you already know is coming.

Then look at 2027 with clear eyes. If your income is going to be well above the line for the foreseeable future, compare off-exchange plans and, if your health allows, private options. Above the cliff, the marketplace is just a store charging full retail.

Build the tracker so you never guess again

Here's the real problem. Most people estimate their income once a year, at enrollment, and then don't look again until tax season. That's like checking your fuel gauge once at the start of a road trip.

So I built a tracker, and I'd build one if I were you.

Every month on the fifth, a scenario in Make.com pulls year-to-date profit from my bookkeeping software, adds any W-2 wages and investment income I've logged, and annualizes it. It subtracts planned retirement and HSA contributions, then compares the projection to the 400 percent line for my household size. If the projection crosses 90 percent of the line, I get a message. If it crosses 100 percent, I get a louder one with a list of levers and how much room each has left.

It took about 90 minutes to set up. It's saved me from having to remember the most expensive number in my year.

For the scenario modeling, I use Galaxy.ai. I paste in my projected income, my contribution room, and the line, and ask for three scenarios: do nothing, max the cheapest levers, and max everything. It's fast math with a clear layout, and it makes the conversation with my CPA a lot more specific than "so, uh, what should I do?"

And when I sit down with my broker in November to compare 2027 plans, I record the call with Fathom. Plan comparisons move fast and brokers talk in deductible-speak. Having the summary and the action items land in my inbox means I actually compare the plans afterward instead of just picking whichever one I remember.

The 2027 enrollment playbook

When the window opens November 1st, work it in this order.

First, finish the 2026 cleanup. You want to know roughly where 2026 is landing before you project 2027, because the same levers are going to show up again.

Second, build an honest 2027 projection. Not a hope. A projection with a documented basis: last year's actual, adjusted for known changes. If the marketplace ever asks how you got your number, you want an answer that holds up.

Third, design the year before it starts. Decide now how much you'll defer into retirement accounts, whether you'll use an HSA-eligible plan, and when you'll take any big gains. If you're an S corp owner, set your 2027 salary with the cliff in mind, since salary drives both the deferral room and your AGI.

Fourth, shop, don't renew. With a median requested increase around 15 percent, auto-renewing is the most expensive button on the site. Compare the benchmark silver, the lowest-cost bronze, and at least one plan you wouldn't normally consider.

Fifth, enroll by December 15th. Even though the window runs to January 15th in most states, December 15th is the deadline for coverage that starts January 1st.

What this is really about

Most people experience their health insurance subsidy as something that happens to them. A number shows up at enrollment, a different number shows up at tax time, and they hope the two are close.

Operators don't hope. They know where the line is, they know how far away they are, and they know which dials move them. The cliff doesn't care how hard you worked or how smart your business is. It only cares about one number on one line of one form.

Learn that number. Track it monthly. Then decide on purpose which side of the line you want to be on.

Want the worksheet?

I built The Subsidy Cliff Worksheet to do all of this in one place. It includes a MAGI calculator with the 2026 and 2027 poverty lines already loaded for every household size, a lever-ranking sheet that shows how much room you have left in each one, the Make.com tracker blueprint from above, a step-by-step guide for updating your marketplace income mid-year, and the question list I'd bring to a CPA and a broker before open enrollment.

One more thing.

This week's issues all came back to the same idea: the calendar is a strategy, not a formality. That's exactly what we do inside The Grid Inner Circle. Members bring the real numbers, like where their MAGI projection sits right now, and we work through them together on live calls before the deadline, not after.

It's 29 dollars a month. Or grab the lifetime seat for 499 dollars, one time, with every future system, call, and teardown included for as long as the Circle runs. That founding price won't be around once the room fills up, and it's the better deal by a mile if you plan on sticking around.

Reply with the word LIFETIME and I'll send you the details and the link.

See you Sunday.
