I sold my startup 2 years ago

I knew nothing about personal finance when I set up my business

But at acquisition, I realized there were lots of things I *should* have done from a tax & estate planning perspective

This is what I would do today (aka learn from my mistakes)

👇👇
Some disclaimers before we dive in:

- I am NOT a lawyer, talk to a professional as well

- I did NOT do most of this since I was too late to learn about this

- This is the *short* version but I believe captures 90%+ of what's important
Why am I sharing this?

It's messed up that we don't teach anything about money to people

The more this information is gatekept, the more we propagate existing systems

The tax code is complicated af, and until we can change that, we should democratize access to information
Part 1 - Structuring Your Startup

If you build a company for enterprise value (vs cashflow) you should set up a C-Corp

What you want to pay attention to here is QSBS - "Qualified Small Business Stock"

Hold your QSBS stock for 5+ years & you pay no tax on $10M of gains Image
The QSBS $10M limit also applies on a per-shareholder basis

This means every single shareholder & investor also gets the same benefit

So instead of owning all equity yourself, you should have your trusts (more soon) & family members all buy shares in your startup and hold
What if you sell your business before 5 years?

You can perform a QSBS rollover & in 60 days, invest in another qualified small business & keep the clock ticking

Say you hold QSBS stock for 3 years before selling it, you then invest in another biz for 2 years and be eligible Image
It is 100% worth having your attorney look over the QSBS requirements & making sure:

1 - The business qualifies for all the criteria

2 - You have a clear list of things to look out for so you don't accidentally trip up the QSBS qualification

3 - You "multiply" shareholders
QSBS applies on a Federal level, some states also observe QSBS while others don't

I know some people who have moved states to save on QSBS taxes

Personally I think that's a terrible idea, and if you let taxes determine where you live, you're doing life wrong

But... you do you
Even if you do not hit the QSBS threshold:

You can have family members (not you or parents) buy shares early on from their self-directed retirement accounts

If they buy from their Roth IRA, the gains are tax-free

Even otherwise, the gains can compound tax-free
Sidenote: If you are likely to have multiple business interests, the structure that Alphabet / Berkshire Hathaway employs may be of interest to you

You can apply this strategy to each and every sub-corp separately, with different shareholders

Part 2 - Structuring Your Estate

Your estate is the sum of all you got (assets minus liabilities)

You want to be very thoughtful how you structure this for the sake of all your dependents - the ones you have, and the ones you will have in the future
You will die - or even if you are alive, you will want to share your wealth with your family

And if you have a large estate, your dependents will be taxed heavily on everything they receive unless you plan for this accordingly

Enter a Grantor Retained Annuity Trust, or GRAT
The way a GRAT works is:

- You move your shares to a GRAT with your dependents as a beneficiary

- The present value of your shares count as a "gift" (subject to gift tax) but all appreciation is transferred without any gift / estate taxes

So you wanna ideally set one up ASAP
Best case, you do this when you set up your startup so the entire upside is captured by your dependents

But this can still work as long as it's relatively early in your company journey

Allegedly, Mark Z placed FB shares pre-IPO in a GRAT that have since appreciated ~$50M
You can also set up non-grantor trusts for the benefit of your family

You have to appoint a trustee & lose control over the assets, but they serve as a QSBS "multiplier"

The $10M limit applies separately to you and each trust, while protecting the gains from gift & estate taxes
✅ All done

This is the quick & dirty version of what you should do early on

You can always dive further into the rabbit hole, but there are decreasing marginal returns

And other stuff (i.e. google "DING" etc) starts getting pretty shady and I'd avoid it
Final note - I wish I did this when setting up my startup, but I'm super happy about how everything turned out

Something I frequently think about:

The people who spend the most amount of time optimizing their taxes tend to be some of the unhappiest people I know...

A financial engineering trick used by wealthy people:

If you have a large balance in your brokerage account, you can borrow money at US treasury rates (~4%)

This is cheaper than a mortgage, and you can deduct the interest you pay as a capital loss!

Here's how it works:
The strategy is called a box spread loan, & it entails buying & selling options to create a theoretically 0 risk trade

You receive cash upfront at an interest rate comparable to the current treasury rate or 4% as of today

And the interest is deductible as a capital loss!
You execute 4 trades on a single ticket against European-style index options like SPX

- Buy lower strike put
- Sell higher strike put
- Sell lower strike call
- Buy higher strike call

This creates a net credit, which is the amount you borrow & get access to on execution

Most people think the money in their retirement accounts is locked away until they turn 60 years old

But, that isn't always the case!

There are a bunch of fully legal loopholes to get some of the money out at any time, without any penalties

Here are my 5 favorites:
1 - Roth IRA contributions

You can withdraw the dollars you contribute to your Roth IRA at any time, for any reason

Since it's after-tax money, you'd owe no taxes and no penalties

But be careful, as you can't put it back in!

Even works for the Mega Backdoor Roth IRA loophole
2 - Roth IRA conversions

When you convert a pretax IRA to a Roth IRA, you can access the converted amount after 5 years

You don't need to wait until retirement!

Ted Weschler famously converted a $100M Traditional IRA to a Roth IRA & can now access the amount before retirement

One of the craziest loopholes in the US tax code gets better this year

If you make $160K+, you can no longer directly contribute to a Roth IRA

But, you can instead use your 401k plan to now contribute $72K to your Roth IRA every year

Here's how the "mega backdoor Roth" works:
Roth IRAs are awesome

You don't get a tax break when you contribute, but then pay zero taxes in retirement

Even if the account grows to millions!

It's so effective at reducing taxes that the IRS doesn't allow anyone earning $168K+ to directly contribute to a Roth IRA
But, here's where the "mega backdoor Roth" loophole comes in!

401k plans have an annual limit of $72,000 in 2026

However, most people don't hit that limit since your employee contribution maximum is only $24,500 this year

Tons of wasted room for high earners

I just made my 2026 Backdoor Roth IRA contribution for $7,500

Most high earners don't do this because they think it's a complicated strategy that isn't worth the effort

But, you typically can do it in less than 5 minutes with 3 simple steps:
Who is a Backdoor Roth IRA for?

If you want to make a full Roth IRA contribution directly, you need an annual income (MAGI) of less than $153K (single) or $242K (married)

If you are above these numbers, you need to use a Backdoor Roth IRA strategy to still fund your Roth IRA
Step 1: Clear out your pretax IRAs

If you have any Traditional IRA dollars (including a SEP IRA), move it to your 401k plan at work or a Solo 401k

This ensures you won't owe any taxes on the Backdoor Roth

Keep these accounts at $0 until December 31

I stopped investing in index funds this year

Instead, I started "direct indexing" - I use an app to buy every single company in the index individually

My results:
- Up almost 20% for the year (same as an index fund)
- More than $70K in tax savings

Here's how it works: Image
With direct indexing, you own all 500 companies directly

Even when the overall stock market is up (like this year), a bunch of those 500 companies are down

The DI software sells some of these losing positions along the way to book a tax loss while still tracking the index
This was my first year trying this strategy:

- My portfolio is up almost 20% for the year (comparable to owning the index)

- Harvested $140K+ of losses, which will save me $70K on taxes since I have gains elsewhere

- A tracking error against the index of +0.7% in my favor

One of the craziest loopholes in the US tax code

If you earn $150K+, you can no longer contribute to a Roth IRA

But, you can instead use a Solo 401k to fund your Roth IRA with $70K every single year

Here's how it works: Image
A Roth IRA is super powerful

You contribute after-tax money, but then never pay any taxes in retirement

You can also withdraw contributions at any time with no penalties

It's so effective at lowering taxes that the IRS has disallowed people earning $150K+ from contributing
However, here's where the loophole comes in:

If you have any self-employment income, you can set up a Solo 401k

This allows you to contribute almost the entirety of your side hustle income up to an annual limit of $70,000 to your Roth IRA

No matter how much money you make!
