Books and taxes for self-defense instructors.
Monthly class tuition, private lesson bookings, a corporate workshop fee, and the studio rent that comes due whether classes are full or not. Gus sorts all of it, an accountant checks every transaction, and you get one number a month.

January came in at $5,200. New Year sign-ups nearly doubled your usual class tuition, so I kept the new enrollments visible against your regular members.

Why your books are different
Self-defense instructor books go wrong in the same four places.
A generalist sees tuition deposits and a rent bill. Your business is a seasonal wave of new sign-ups, private lessons booked one-on-one, and a corporate workshop that pays far more than a single class. When the books do not separate that, it is hard to see what actually grows the business.
-
1
A new year sign-up wave looks the same as steady enrollment
January and September bring a burst of new students trying self-defense for the first time, and without separating new sign-ups from returning members, you cannot tell how many actually stick around past the first month.
What we doFlags seasonal enrollment surges against your regular member count, so you can see who is trying it out versus who stays.
-
2
Private lessons and group tuition blur together
A one-on-one private lesson bills at a very different rate than a group class, and mixed into one tuition number, you cannot tell whether private lessons are worth the extra time they take.
What we doKeeps private lesson fees apart from group class tuition, so each part of the business shows its real worth.
-
3
A corporate workshop's real cost gets missed
A one-time workplace self-defense workshop pays well, but travel time, extra insurance, and prep time for a group that has never trained before cost more than a regular class night. Filed like ordinary tuition, that extra cost disappears.
What we doKeeps corporate workshop revenue and its extra costs together, so you know the real margin on outside events.
-
4
Studio rent looks the same in a full month and an empty one
Rent is a fixed cost whether ten students show up or two, and without tracking enrollment against rent, a slow month is easy to mistake for a pricing problem instead of a seasonal dip.
What we doTracks tuition against fixed studio costs, so a seasonal dip reads differently than a real pricing issue.
Your categories
The categories Gus keeps for a self-defense instructor.
Set up once for how you bill and what you spend. You never pick a category. He does, and an accountant checks it.

What we watch for you
- New sign-up retention
New students still enrolled after 60 days. Shows whether seasonal surges turn into real growth.
- Private lesson share
Private lesson revenue against group tuition. Shows if one-on-one time is worth the hours it takes.
- Rent coverage
Tuition against fixed studio rent. A tight month shows whether it is seasonal or a real pricing issue.
- The set-aside
What you will owe on tuition and lesson income, tracked monthly so April is no surprise.
Ask Gus
Things self-defense instructors 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.
I flagged those as new sign-ups, separate from your regular members. Worth checking back at 60 days to see how many are still coming.
Once I add the extra insurance and prep time against the fee, it still cleared a solid margin. I keep workshop costs together so you can check any future one the same way.
Tuition was down from the usual slow season, not from pricing. Rent stayed fixed while enrollment dipped, which is normal for this time of year.
The tax side
The tax side of a self-defense instructor business.
Most of what goes wrong here is a set-aside that never gets started and gear that could be written off faster. Get those right and the rest is straightforward.
What your return has to get right
Your accountant signs it, so it gets done right the first time.
- Self-employment tax for solo instructorsAn instructor running the business alone without employees pays 15.3 percent self-employment tax on top of income tax, so a monthly set-aside matters even without a payroll to manage.
- Equipment write-offs for mats and gearTraining mats, pads, and practice equipment can often be written off in the year you buy them rather than spread out over several years.
- Contractor 1099sAnyone not on payroll who you paid $2,000 or more in 2026, such as a guest instructor for a workshop, gets a 1099-NEC by January 31. Gus keeps the list all year.
- The pass-through deductionMost owner-operators can take up to 20 percent of business profit off their taxable income, on top of studio rent and gear costs. It comes out right when tuition and expenses are tracked all year.

All year, not just April
A self-defense instructor's year, kept every month.
Enrollment swings with the seasons, but taxes 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
Enrollment planned for the year
Last year's return gets started, the 1099 list for guest instructors is ready, and you get a monthly set-aside so April is already handled.
- April
Filed while classes stay full
Your return is filed and signed. No surprise bill, thanks to the set-aside running since January.
- July
A midyear enrollment check
Where you stand, what you will owe, and whether summer enrollment has held steady.
- October
Before winter enrollment
Fall often brings a second wave of new students. Gus looks at gear worth buying and moves worth making before December.

Straight answers
Questions self-defense instructors ask first.
Can Gus tell new students apart from returning members?
Yes. He flags a new enrollment against your regular member base, so you can see whether a busy month is real growth or a short-term surge.
I collect tuition through Mindbody. Do I have to change anything?
No. Keep running classes the way you do. Gus works from your bank statement, and when a deposit is unclear he asks you once and remembers the answer.
How does Gus handle a corporate workshop that pays a lot more than a regular class?
He keeps the workshop fee and its extra costs, like travel and prep time, together so you can see the real margin instead of comparing it directly to tuition.
Do I need to track private lessons separately from group classes?
It helps. Gus keeps them apart so you can see whether one-on-one sessions are worth the extra time compared to group tuition.
My books are behind from a busy enrollment season. Is that a problem?
No. Send whatever statements you have. Gus works through tuition and lesson deposits and tells you where you stand, usually within 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.
