The Quarterly Tax Nobody Told You About

You're self-employed. You have a lot going on. Here's the thing the IRS is counting on you forgetting.

Let's talk about estimated taxes. Specifically, let's talk about the look on someone's face the first time they get hit with an unexpected tax bill in April — not because they did anything wrong, but because nobody ever explained that self-employed people pay taxes four times a year.

If you work for someone else, your employer withholds taxes from every paycheck and sends them quietly to the IRS on your behalf. You never think about it. It just happens. The IRS gets its money in steady little installments all year long, and everyone is happy.

When you're self-employed — which describes most travel agents and photographers — there is no employer doing that for you. The IRS still wants its money in installments. They've just moved the responsibility over to you, without making a particularly big announcement about it.

Those installments are called quarterly estimated tax payments. They're due four times a year: April, June, September, and January. Miss them, and you don't just owe the tax later — you may also owe a penalty for underpayment, which is the IRS's polite way of charging you interest on money they feel you should have sent months ago.

Here's the part that trips people up: the amounts aren't fixed. They're based on what you expect to earn, which for a travel agent in the middle of booking season or a photographer with a packed fall calendar, can be genuinely hard to predict. Too low and you get penalized. Too high and you've given the government an interest-free loan. Neither is ideal.

The good news is this is completely manageable with a little planning. A bookkeeper who understands your business — the seasonal income, the slow months, the big commission checks that don't arrive until 90 days after the booking — can help you estimate accurately and avoid the April surprise.

We've sat with a lot of people who found out about estimated taxes the hard way. No judgment. It's genuinely confusing, and the IRS does not hand out a welcome packet when you go self-employed. But once you understand how it works, it stops being scary and starts being just another thing on the calendar.
