For the online sellers: "Amazon collects the sales tax for me, so I don't have any sales tax obligations."

Partly true.

And the part that isn't true is where the problems live.

Marketplace facilitator laws mean Amazon, Walmart, Etsy and similar platforms generally collect and remit sales tax on sales made through their platform, in most states.

But they only cover sales on their platform.

Your own Shopify store, wholesale orders, anything sold through your own site, that's still yours to handle.

Some states also expect you to register or file returns even when every sale is facilitated.

And your marketplace sales can count toward the economic nexus thresholds that apply to your direct sales.

So "Amazon handles it" is usually true for the Amazon channel and dangerously wrong for everything else.

A scenario on why October projections matter (details changed).

An e-commerce owner doing about $2.5M in revenue was having his best year ever and assumed his quarterly estimates had him covered.

They were based on last year's income.

This year's profit was running close to double.

When we projected the full year in October, the gap was obvious.

Without changes he was headed for a large April balance plus an underpayment penalty on top.

Because it was still October, we had options.

We adjusted his Q4 estimate, looked at a retirement plan that could still be established for 2026, and reviewed the timing on a big inventory and equipment decision he was already weighing.

April still came with a balance.

But it was a number he'd seen coming for months, not a surprise that wrecked his cash flow in the spring.

Every situation is different.

But the best tax outcomes almost always start with seeing the number early.

Let's talk about the IRS calls that aren't from the IRS.

Every fall the impersonation scams ramp up.

A caller says you owe back taxes, there's a warrant pending, and you need to pay today by wire, gift card, or crypto.

Some of the texts even have your real name and address in them.

Here's how the real IRS works.

They almost always make first contact by mail.

They don't demand immediate payment over the phone.

They don't threaten arrest.

And they never, ever ask for gift cards or cryptocurrency.

The scary part is these scams work best on people who actually have a tax problem.

If you already know you're behind, a call like that feels plausible.

So the rule is simple.

Never pay based on an inbound call or text.

Hang up.

Then check your real balance through your IRS online account or through your tax professional.

If you do owe, the real fix runs through real channels.

A Sunday thought on timing.

October is the most valuable month of the year for tax planning, and most business owners spend it doing nothing.

Think about why.

By now you have nine months of real data.

Revenue, margins, big purchases, property deals.

Most of the year has actually happened.

But you still have almost a full quarter to act on it.

Retirement plan decisions, equipment timing, property sales, estimated payments, salary adjustments for S-Corp owners.

All still on the table.

Wait until December and half of those options are gone or rushed.

Wait until April and they're all gone.

What I want every client to have in October is a projection.

Here's what you'll likely owe if nothing changes, and here are the moves that could change it.

If you don't know your projected 2026 number right now, that's the first thing to fix.

Follow along, I'll break down the moves all month.

Here's a scenario that plays out every October (details changed, as always).

A consultant running a single-member LLC came to us on extension, netting a little over $300K for the year.

He assumed the year was over.

The only thing left to do, in his mind, was calculate the damage and pay it.

No retirement plan at all.

No employees.

Clean books.

So we opened a SEP-IRA the first week of October and funded it before the extended deadline.

That contribution came straight off his 2025 taxable income, on the return we were already preparing.

Same money.

It just landed in his retirement account instead of the Treasury.

Then we talked about next year, because a SEP probably isn't his best long-term fit.

A solo 401(k) may let him put away more at his income level, and that's a decision to make before December, not after.

The lesson isn't that October is magic.

It's that "the year is over" is almost never fully true until the return is filed.

Stick around, there's more like this all month.

Let's open October with a myth that gets more expensive every day this month: "I filed an extension, so I have until October 15 to deal with my taxes."

You have until October 15 to file.

You never had until October 15 to pay.

An extension moves the paperwork deadline.

That's all it does.

The payment was due in April, and if there's a balance sitting out there, interest and the failure-to-pay penalty have been running on it since then.

I'm not saying panic.

I'm saying stop treating the extension like a pause button.

The number is growing quietly while the return sits unfinished.

If you're on extension and you already know you owe, finishing the return and paying now beats finishing it on the 14th.

Two weeks of interest isn't nothing.

The extension buys you time to get it right.

It doesn't buy that time for free.

Thirteen days.

That's what anyone on a personal extension has left until October 15, and I want to be very clear about what happens if you miss it.

There is no second extension.

October 15 is the wall.

Miss it with a balance due and the failure-to-file penalty kicks in: 5% of the unpaid tax per month, up to 25%.

And it isn't counted from October.

It's counted from the original April due date.

That's the part that surprises people.

The extension only protected you if you actually file by the extended date.

Blow through it and you lose that protection going all the way back.

The failure-to-file penalty is also about ten times harsher than the failure-to-pay penalty.

So if you can't pay in full, file anyway.

Filing is what stops the bigger bleed.

If your return is stuck because the books aren't done or a K-1 never showed up, that's solvable.

Just not on October 16.

Last one for the month — an illustrative example that isn't dramatic, which is exactly why I like it.

A business owner around $2.5M in revenue came to us with no crisis.

No notices, no back taxes, books in decent shape.

His only complaint: he never knew what he owed until his CPA told him in March, and the number was always worse than he hoped.

So we didn't start with a strategy.

We started with a projection.

Where his income was landing, what the tax looked like at current structure, and where the gaps were.

From there the strategies picked themselves.

Some retirement restructuring, an entity-level state election he'd never been told about, timing decisions on a property sale, and a cleanup of how his books handled a few recurring items.

Then we set a rhythm.

A conversation each quarter, an updated projection, and a decision or two made while there was still time to make them.

Two years in, what he says he values isn't the savings.

It's that April stopped being a surprise.

He knows the number in October and he's already decided what to do about it.

That's what proactive actually looks like — unremarkable, on schedule, and quiet.

Thanks for following along this month.

Closing the month with the thing I most want business owners to understand about IRS problems: the balance is not the emergency.

The silence is.

Every option that exists — installment agreements, offers, hardship status, penalty relief, correcting a bad assessment — depends on being in the system and responsive.

Almost all of them get harder or disappear when you go quiet.

Levies, liens, and garnishments aren't the IRS's opening move.

They're what happens after a sequence of letters went unanswered.

The system escalates against non-response, not against debt.

And the arithmetic of waiting is unforgiving.

Penalties accrue, interest compounds on the penalties, and a balance you could have addressed doubles while you decide whether you're ready to look at it.

I've never once had someone come in and find out it was worse than they feared.

Not once.

The imagined number is always bigger, because fear doesn't do math — it just repeats.

Whatever year is unfiled, whatever notice is in the drawer, whatever balance you've been carrying: it is a solvable problem with a defined process.

It only becomes unsolvable through avoidance.

Nothing here fixes itself, and nothing here is unfixable.

One number most business owners can't tell me, and it's the one that matters: their effective tax rate.

Everybody knows their bracket.

The bracket is a marginal rate — it applies to your last dollar of income.

Your effective rate is total tax divided by total income, and it's usually meaningfully lower.

Both are useful, for different questions.

When you're deciding whether to accelerate income or take another deal, the marginal rate is the number that matters.

When you're judging whether your overall structure is working, the effective rate is the scoreboard.

Then there's the third rate nobody computes: what you're paying including self-employment or payroll tax, state tax, and phased-out deductions.

For a business owner in a high-tax state, that combined figure is frequently a shock.

This is why I build projections rather than waiting for returns.

A projection run in the fall tells you your expected income, your expected tax, and — critically — what each available strategy is actually worth in dollars.

That last part changes decisions. “Cost segregation could help” is an idea.

“This produces roughly this much deduction and saves you roughly this much at your rate” is something you can act on.

You can't manage a number you've never calculated.
