What exactly counts as "reasonable" interest? My parents want to charge me 1% interest on a house loan which is obviously way below market rate. Is that going to be a problem?

The IRS publishes what's called the Applicable Federal Rate (AFR) each month, which is the minimum interest rate they consider legitimate for loans. These rates are typically lower than commercial rates. For example, as of last month, the long-term AFR (for loans over 9 years) was around 3-4%. If your loan charges less than the applicable AFR, the IRS might "impute" interest, meaning they treat the loan as if it charged the minimum rate even if it doesn't.

Without proper documentation, the IRS could potentially reclassify that $200k as a gift rather than a loan, which could have significant consequences. The annual gift tax exclusion is only $17,000 per person (as of 2023), so amounts beyond that would count against your grandparents' lifetime gift/estate tax exemption.

Thanks for pointing this out! We actually did a bathroom remodel (~$22k) and replaced all the windows (~$15k) a few years ago. I have receipts for everything. Do these improvements get listed somewhere specific on the tax forms?

You'll add those improvement costs to your original purchase price when calculating your adjusted basis on Form 8949. So if you bought the house for $200k and did $37k in improvements, your adjusted basis would be $237k. The difference between your selling price (minus selling expenses) and this adjusted basis is your actual gain for tax purposes. This means your real gain is likely even lower than you initially calculated, putting you even further below the $500k exclusion threshold. Still need to report it though!

You'll list it on Form 8949 first (Part II for long-term holdings) with code "H" in column (f), then the excluded amount as a negative number in column (g). Then the totals flow to Schedule D, Line 8. If you're using software like TurboTax or H&R Block, they should walk you through this if you tell them you sold your primary residence.

Wow, I hadn't thought about the basis step-up issue at all. Does this mean I should be gifting cash rather than appreciated investments if I do start annual gifting? Or is there some strategy that lets you get the best of both worlds?

Yes, if you're going to gift, cash or high-basis assets are generally better from a tax perspective. You want to keep the low-basis (highly appreciated) assets in your estate to get that step-up when you pass. Another strategy some people use is life insurance. If you're worried about estate taxes but want to preserve the step-up, you can keep your appreciated assets and buy life insurance in an irrevocable life insurance trust (ILIT) to provide liquidity for any estate taxes. The insurance proceeds, if structured correctly, pass outside your estate and can be used to pay any estate tax due, allowing your heirs to keep more of your assets intact.

I disagree with your "use it or lose it" framing. While you can't recover unused annual exclusions, you still have your lifetime estate/gift tax exemption. So it's not like those opportunities to transfer tax-free are gone forever if you don't make annual gifts. Also, compounding works the same whether the money is in your account or your child's account. The real question is whether you think you'll exceed the lifetime exemption (even after it decreases), which most people won't.

Yep, this is critical. Texas has the same issue - my LLC that's taxed as an S-corp still has to file and pay franchise tax even though federally we're an S-corp. Cost me $3,500 I wasn't expecting my first year.

This is huge! We had to do the same thing. Our attorneys said converting from LLC to C-corp cost us an extra $11k in legal fees compared to if we'd just started as a C-corp. Depends on your longterm goals I guess.

Would this apply to a small retail business too or mainly tech startups? We might seek a small business loan but not planning on angel investors or anything fancy.

11 Is that different from the mega backdoor Roth? I've heard about that one but don't fully understand it. Something about using your 401k?

22 Yes, they're different strategies. The regular backdoor Roth is what I described - contributing to a traditional IRA then converting to Roth when your income exceeds the limits for direct Roth contributions. The mega backdoor Roth involves making after-tax (not Roth) contributions to a 401(k) plan above the standard employee contribution limit, then either converting those to Roth inside the plan or rolling them over to a Roth IRA. It requires a 401(k) plan that specifically allows after-tax contributions and in-service distributions or rollovers. The potential contribution amounts are much larger - potentially up to $40,000+ per year depending on your plan's limits and your other contributions.

16 Are there companies that help set up self-directed IRAs? My regular brokerage only lets me invest in standard stuff like stocks and ETFs.
