How much should a pest control business set aside for taxes?

If you run a pest control business, the scariest line item of the year isn't a truck repair or a chemical price hike. It's the tax bill you didn't see coming — the one that shows up in April when the cash is already spent.

Here's the uncomfortable truth most owners learn the hard way: the money in your checking account is not all yours. A chunk of it belongs to the IRS, and the only question is whether you've already moved it somewhere safe or whether you're going to scramble to find it.

This guide gives you a dead-simple way to never be surprised again. It's not tax advice — talk to your accountant for your specific situation — but it's the framework we see well-run home-service businesses actually use.

Why pest control owners get caught off guard

Pest control is cash-heavy and seasonal. You collect a big chunk of revenue in the termite and mosquito months, and the deposits hit your bank account looking like profit. They aren't. Inside every deposit is money for:

• Cost of services (chemicals, fuel, tech wages)
• Operating expenses (insurance, software, the office)
• Taxes you owe on the profit
• What's actually left for you

If you spend out of one undifferentiated checking account, you're spending tax money without realizing it. Then the bill comes due in a slow season when cash is already tight. That timing mismatch — money in during peak, taxes due during the lull — is what wrecks otherwise healthy pest companies.

The simple rule: set aside a percentage of every deposit

You don't need a forecasting model. You need a percentage and a discipline.

The Profit First approach (a method we like because it works for owner-operators who aren't finance people) says: the moment money lands, split it into buckets — before you get used to seeing the full balance. One of those buckets is Tax.

For most pest control owners taxed as a sole proprietor or pass-through (S-corp, LLC), a reasonable starting set-aside is 25–30% of net profit — not revenue, profit. That covers:

• Federal income tax on your business profit
• Self-employment tax (roughly 15.3% on the first chunk of self-employment income — this is the one new owners forget)
• State income tax, where you have it

If you don't yet know your net profit number cleanly, a blunter rule of thumb many owners use early on is to move 10–15% of every deposit into a separate tax account. It will be roughly right for a healthy pest business, and you'd rather over-save and get a refund than under-save and panic.

A quick illustration: say a pest control business does a $40,000 revenue month. If profit runs around a third of that — call it $13,000 — a 27% tax set-aside is about $3,500. Moving that $3,500 out the day it lands is the entire game. (Your real numbers will differ; this is just to show the mechanics.)

Step 1: Open a separate tax account

This is the part owners skip, and it's the part that matters most. Open a second business savings account labeled Tax. Not a sub-category in your head — a real, separate account.

The whole trick of Profit First is removing temptation. If the tax money is sitting in your operating checking account, you will spend it on a truck repair in July and tell yourself you'll make it up later. You won't. Move it where you can't casually touch it.

Step 2: Move the percentage every time money comes in

Pick a rhythm:

• Per deposit is best — every time a customer payment or batch settles, transfer your tax percentage.
• Twice a month (the 10th and 25th) is the Profit First cadence and works great for pest control because it matches how often you're reconciling anyway.

Whatever you choose, automate or calendar it so it actually happens. A percentage you only move "when you remember" is a percentage you don't move.

Step 3: Pay quarterly estimates so April is a non-event

The IRS expects business owners to pay taxes throughout the year via quarterly estimated payments (generally due in April, June, September, and January). Your tax savings account is where those payments come from.

Do this right and April stops being a cliff — you've already paid most of what you owe, and the final return is a small reconciliation instead of a five-figure surprise.

Where Ando fits in

The hard part of all this isn't the math — it's knowing your real numbers so your set-aside percentage is grounded in reality instead of a guess.

That's exactly what Ando Forecast does. It connects to your bank and QuickBooks and shows you what's actually profit versus what's already spoken for — including a Profit First allocation view that tells you the dollar amount to move to your tax and profit accounts on the 10th and 25th. No spreadsheet, no bookkeeper required.

We also benchmark pest control specifically. The industry runs around a 58% gross margin (per the NPMA 2025 cost study), and Ando compares your numbers against that — so when your margin slips, you find out before it shows up as a smaller-than-expected profit at tax time.

The one-paragraph version

Open a separate tax account. Move 25–30% of profit (or a blunt 10–15% of every deposit) into it the day money lands. Pay your quarterly estimates from it. Do that, and the tax bill that used to blindside you in April becomes a number you already have sitting in the bank.
