Stop waiting until April to think about taxes.
If you're a founder past your first million, your tax bill isn't just paperwork. It's one of your biggest bills every year. Most people don't treat it that way until the money is already gone.
What waiting actually costs you
Most founders I talk to already have someone who files their return. What they don't have is a plan.
Not knowing your numbers is like driving somewhere new without GPS. You'll end up somewhere. You just won't know if it's where you wanted to go. That's how a lot of business owners run their money. Revenue goes up, but nobody mapped the foundation underneath.
The leaks are quiet. You never filed the S-corp election. You missed quarterly tax payments and got hit with penalties. You skipped retirement contributions because nobody told you the deadline. You had write-offs you could've taken but never saved the receipts.
Stack that over three or four years and you're not talking about a few thousand dollars. You're talking about six figures. Money that was yours. Gone. Because the plan came after the fact instead of before.
That's the difference between tax preparation and tax planning. Preparation looks at what already happened. Planning sets you up before the year ends.
Why your "tax guy" might not be enough
Having the right tax help is like going to a brain surgeon instead of a general doctor. If you're making real money and running a real business, you want someone who plans with you all year. Not someone who only shows up in April.
Getting your return filed is fine. But if that's the whole relationship, you're paying someone to check boxes when you should be paying someone to help you keep more.
The tax code is built for business owners. The rules are there. The deductions are there. The entity setups are there. Most people are too busy running the business to learn all of it. That's kind of the point. The system stays confusing on purpose.
Your job is to make money. Your advisor's job is to make sure you actually know your numbers and keep as much as the law allows.
Real talk: the $400K line
If you're under $400,000 a year, don't obsess over advanced tax moves yet. Get your structure clean, take the easy wins, and focus on making more.
This piece is for founders past that line. Past the first million. Running a real business with real profit and a real tax bill.
At that level, taxes are one of your biggest expenses. Planning stops being optional.
What I actually set up for founders past $1M
This is the same stuff I walk through with clients. Not theory. The real checklist.
1. Your business structure (and how you pay yourself)
How you set up your business isn't a one-and-done decision. It should change as your income grows.
For a lot of founders, electing S-corp status makes sense once profit is high enough. But it comes with rules. The IRS wants reasonable pay for owners who work in the business. Pay yourself too little and you can get flagged. Pay yourself with no plan and you overpay on payroll taxes.
Think of an S-corp like being both the employee and the boss. The IRS taxes those two parts differently. That gap can save you real money. But only if someone sets it up right and keeps it updated.
Check your structure at least once a year. If your income doubled since you last looked, your old setup might be costing you.
Picture this: A founder doing $90K/month on a default LLC keeps paying self-employment tax on almost all of it. Same person, right S-corp setup, right salary split? The annual savings can be enough to fund a hire.
2. Quarterly tax payments (so you don't get surprised)
If you're self-employed or your business income flows straight to your personal taxes, the IRS wants you paying throughout the year. Not one giant payment in April.
Miss those payments and you owe penalties on top of what you already owe. I see this all the time with founders who crushed it all year, then get wrecked by a surprise bill plus interest.
The fix is boring but it works: know what you're on track to make, estimate what you'll owe, and pay every quarter. Clean bookkeeping helps so you're working from real numbers, not vibes.
A tax plan is like a personal trainer giving you a workout plan. Someone still has to do the reps. Your books tell you if you're actually doing them.
3. Retirement accounts (they lower your tax bill now, not just later)
A lot of founders past $1M leave retirement money on the table because nobody mapped it out.
A Solo 401(k) or SEP IRA can shield a big chunk of income while you build wealth for later. The limits for self-employed people are way higher than a normal job 401(k). And you get the tax break the year you put the money in.
It's not just "retirement stuff." It's a way to pay yourself instead of the IRS this year.
4. Write-offs you can actually prove
Most founders know write-offs exist. Fewer track them every month.
Publication 535 covers business expenses: home office, car miles, software, gear, travel for work, contractors. The write-offs are real. What saves you in an audit is the paper trail.
Track it monthly. Not in December when you can't remember what that charge was.
Home office? Log it. Car for work? Log the miles. New laptop or course? Tag it when you buy it.
Clean books pay for themselves fast.
5. A year-round rhythm (not one panic week in March)
Tax planning isn't a single meeting. It's a calendar.
Four times a year, check in on: estimated taxes, write-offs, business structure, retirement contributions. Do a mid-year check so Q4 doesn't blindside you.
Founders who plan all year don't panic in March. They already know their number. They already made the moves. April is just confirmation.
Mark Kohler's The Tax and Legal Playbook says it well: the tax and legal side isn't separate from your business. It's part of how you run it.
The 20% deduction a lot of founders miss
If your business is set up as an LLC, S-corp, or partnership, you might qualify for the Qualified Business Income deduction. That's up to 20% off certain business income. There are income limits and rules based on what you do.
It's not a hack. It's in the tax code. But you need the right setup, the right pay structure (for S-corps), and real records. Founders who don't plan often miss it completely.
Who this is for
This is for founders past their first million who are serious about keeping more of what they earn. Real business. Real profit. Taxes showing up as one of your biggest line items.
If you're earlier in the journey, that's cool. Advanced tax strategy isn't where your focus should be right now. You'd be paying someone to save money you're not really losing yet. Go make more, get your structure clean, and come back when you're there.
No shame. Just honest.
The short version
- Tax planning and tax preparation aren't the same. Planning looks ahead. Preparation looks back.
- Founders past $1M who skip planning often lose six figures over a few years without noticing.
- Review your business structure and pay setup every year as income grows.
- Pay estimated taxes quarterly so you don't get penalties.
- Solo 401(k)s and SEP IRAs lower your tax bill now, not just in retirement.
- Track write-offs monthly. Home office, car, gear, contractors.
- Put four quarterly check-ins on the calendar. Don't wing it in April.
FAQs
What's the difference between tax planning and tax preparation for founders?
Tax preparation is filing based on what already happened. Tax planning is setting up your business, pay, write-offs, and payments during the year so you keep more. Founders past $1M need both. The big savings are in planning.
When should a founder think about an S-corp election?
Usually when profit is high enough that a reasonable salary plus S-corp costs still leaves real savings. A lot of founders start looking around $80K to $120K in net profit. Revisit it as income grows.
How much should I set aside for quarterly taxes?
A lot of people start around 25–30% of net profit for federal and state combined. Your real number depends on your setup, write-offs, and other income. Run the math with your advisor on your actual numbers.
Do I need a tax advisor if I already have a CPA who files my return?
If your CPA only files and doesn't plan with you during the year, you probably have a preparer, not a strategist. At high income, that gap costs real money. You want someone who helps you move before December 31, not after.
What's the biggest tax mistake founders make past $1M?
Waiting. Waiting until April. Waiting until profit feels "high enough." Waiting until penalties show up. By then, the best moves for that year are often gone.
