Restoration & remediation
Books and taxes for radon testing and mitigation companies.
Short-term test orders, sub-slab depressurization installs, real estate closing waves, and warranty callbacks on fans you installed years ago. Gus sorts all of it, an accountant checks every transaction, and you get one number a month.

March made $8,000. Real estate agents sent over a wave of test orders ahead of spring closings, so testing fee income jumped while mitigation installs stayed steady.

Why your books are different
Radon books go wrong when tests and installs blur together.
A generalist sees deposits and bills. Your business is a cheap test that leads to an expensive install, a market that runs in waves tied to home closings, and warranty callbacks years after the original job. When the books do not separate those pieces, the real picture disappears.
-
1
Test fees and mitigation installs are really two businesses
A test order and a sub-slab depressurization system get paid, costed, and margined completely differently, and if both land in one generic service revenue line, there is no way to tell whether testing is a lead generator or a real profit center on its own.
What we doKeeps test fees and mitigation installs in separate categories so each side of the business shows its own numbers. -
2
A continuous monitor looks like a cheap test kit
A continuous radon monitor used for short-term tests can cost close to a thousand dollars, and bought alongside disposable charcoal canisters, it gets expensed the same way and throws off equipment depreciation.
What we doFlags equipment over a set size the day it shows up and logs it separately for the accountant. -
3
Real estate closing timelines create a wave, not a trickle
A busy stretch of home closings can bring ten test orders in a week followed by a slow week with almost none, and an owner who only watches weekly totals can misread a normal swing as a problem.
What we doTracks the month as a whole and tells you when a slow week is just the calendar, not a trend. -
4
Warranty callbacks eat into a job's margin
A mitigation system installed with a multi-year warranty can mean a free return visit to replace a fan or reseal a crack, and if that labor and part cost is not tracked against the original job, the true cost of a warranty promise stays invisible.
What we doTracks warranty callback costs against the original install so you know what a warranty is actually costing you. -
5
Certification renewal costs get lost in general fees
State radon licensing and certification renewal has its own fee and schedule, separate from a general contractor license, and buried in a catchall fees category, it is easy to lose track of when it is due.
What we doKeeps certification costs in their own line and flags a renewal deadline before it is missed.

Ask Gus
Things radon testing and mitigation owners ask Gus.
Text him like you would text anybody. He answers in plain English, and when a question is above his pay grade, an accountant looks and gets back to you.
A run of home closings pushed ten test orders through in one week. I kept the month as a whole so a normal swing does not read as a problem.
Usually it can. I logged it as equipment, not a kit, and flagged it so the accountant makes the call with your whole year in view.
No, I tracked that callback against the original install, so you can see exactly what the warranty cost you on that job.
The tax side
The tax side of a radon testing and mitigation business.
Most of what goes wrong here is timing and labels. Equipment filed as a kit, mileage never tracked, and a set-aside nobody started until April.
What your return has to get right
Your accountant signs it, so it gets done right the first time.
- Equipment and continuous monitorsContinuous radon monitors and mitigation equipment bought for the business can usually be written off the year you buy them. Bonus depreciation is back to 100 percent for property acquired after January 19, 2025.
- Vehicle mileageMiles driven between test sites and install jobs can be deducted at 72.5 cents a mile through June 2026 and 76 cents from July on, or by tracking the vehicle's actual costs instead.
- State radon licensingMost states require a specific radon measurement or mitigation license, separate from a general contractor license, with its own renewal schedule. Gus flags the cost when a renewal comes up.
- The pass-through deductionMost owner-operators can take up to 20 percent of business profit off their taxable income. It comes out right when the books are right all year.

General information about 2026 federal rules, not advice for your business. Your accountant looks at your actual numbers before anything gets filed.
All year, not just April
A radon testing and mitigation year, kept every month.
Home sales, not the weather, set your busy season. Your taxes still come on a schedule. Your team keeps you ahead of both. Every month in between, your bookkeeper closes the books and speaks up the moment something looks off.
- January
Plan the year
Last year's return gets started, the 1099 list for any subs is ready, and a monthly set-aside is planned so the spring closing rush does not catch you behind.
- April
Filed. Done.
Your return is filed and signed right as the spring real estate rush picks up. No surprise bill, because the set-aside has been running since January.
- July
Halfway check
Where you stand, what you will owe, and whether the spring closing wave changed the number.

Before the market slows
Before the fall market cools, Gus looks at equipment worth buying and anything worth doing before December.

Straight answers
Questions radon testing and mitigation owners ask first.
Can Gus tell testing income apart from mitigation income?
Yes. He keeps test fees and mitigation installs in separate categories, so you can see whether testing is paying for itself or just feeding your install work.
My income swings a lot with the real estate market. Is that a problem?
No. Gus tracks the whole month, so a slow week during a lull does not get mistaken for a real drop, and a busy closing season does not get overcounted either.
Do I write off a continuous monitor all at once?
Often you can. Equipment bought for the business can usually be deducted in the year you buy it, and sometimes spreading it out is the better call. Gus flags the purchase and the accountant decides.
I had to redo a system under warranty. Does that count against me?
No. Gus tracks the callback cost against the original job, so you can see what honoring a warranty actually cost, not just a general repair expense.
Does Gus handle my state radon certification?
No. Gus keeps the books and flags when a certification renewal fee or deadline is coming up, but staying licensed under your state's rules is on you.
My books are a year behind. Is that a problem?
No. Send the bank statements you have. Gus sorts them, the accountant checks them, and most people know where they stand inside a week.
Is a real accountant checking my books?
Yes. You get your own bookkeeper, Gus does the first pass on every transaction, and an accountant checks every one before your month closes. That same accountant prepares, signs, and files your business return. Goatkeeper is not a CPA firm, and we never pretend a person looked when they did not.
What does it cost, and can I cancel?
It starts at $197 a month, depending on what your business needs. No setup fee, no hourly bills, no contract. Cancel any time from the app, and your books go with you.
