Need help understanding step-up in basis for S-Corps and QSSTs - tax implications?

So does this mean if OP sells their shares right after inheriting them, they basically pay no capital gains tax since the basis just got stepped up to current value? And what about ongoing income from the S-Corp - does the step-up affect how that's taxed too?

If the original poster were to sell their shares immediately after inheriting them at fair market value, they would likely recognize little to no capital gain, since their basis would be approximately equal to the selling price. This is one of the key benefits of the step-up in basis provision. Regarding ongoing income, the step-up in basis doesn't directly affect how S-Corporation income is taxed. As the beneficiary of a QSST, the original poster will continue to be taxed on their pro-rata share of the S-Corporation's income, regardless of whether distributions are made. This income passes through and is reported on their personal tax return. The step-up primarily benefits them when they eventually sell the shares.

How long did it take them to review everything? I've got a similar situation but with multiple trusts and I'm on a deadline for making some decisions.

Sounds too good to be true tbh. Did they actually help with the valuation or just tell you that you needed one? Because business valuations cost thousands of dollars. Did you end up having any issues with the IRS afterward?

They processed my documents in about 48 hours, which was pretty impressive considering how complex the trust structure was. They have a priority option if you're really in a time crunch. They didn't perform the business valuation themselves, but they provided specific requirements for what the valuation needed to include to satisfy IRS requirements, and recommended three reputable valuation firms that specialize in S-Corps. This guidance alone saved me from getting an inadequate valuation that might have been challenged. I've had zero issues with the IRS - the documentation package they helped me prepare was extremely thorough and compliant with all requirements.

Wait, how does this actually work? How do they know when to call you and how do they transfer the IRS call to you? That seems really sketchy.

Yeah right. The IRS never gives clear answers on anything, especially something complicated like QSSTs and basis calculations. I've called them multiple times and always get different answers depending on who answers. No way they actually provided useful guidance on something this complex.

It works through their system where they use automated tech to wait on hold for you. When an IRS agent picks up, you get an immediate call connecting you directly to that agent. It's completely legitimate - they don't impersonate you or anything sketchy. You're absolutely right that IRS agents can sometimes give inconsistent answers. The key is getting to their business tax specialists, not the general helpline. I specifically requested to speak with someone familiar with S-Corporation and trust issues. The agent I reached had been working in that department for 12 years and referenced specific IRS code sections and revenue rulings that applied to my situation. I recorded the call (after informing the agent) so I had documentation of their guidance for my records.

Could you explain this more? What exactly is inside vs outside basis? I'm in a similar situation but with an LLC taxed as an S-Corp and I'm confused about what basis gets stepped up.

Sure thing. Outside basis refers to your basis in the actual S-Corp shares themselves. When you inherit shares, this outside basis gets stepped up to fair market value at the date of death. Inside basis refers to the corporation's own basis in its assets (equipment, buildings, inventory, etc). These do NOT get stepped up when an owner dies - the corporation maintains its original basis in these assets regardless of ownership changes. This distinction is crucial because if the S-Corp later sells assets with low inside basis, the gain flows through to shareholders regardless of their outside basis. Many people mistakenly believe the step-up applies to everything, but it doesn't. Only the shares themselves get the step-up, not the underlying assets of the business.

Yup, I learned this the hard way. Turns out our family trust didn't meet QSST requirements because it allowed for multiple beneficiaries in certain scenarios. Ended up having to do a last-minute restructuring to fix it before it blew up our S-Corp status. Get a second opinion on your trust docs!

This is really helpful advice about timing! I'm dealing with a similar inherited S-Corp situation and had no idea about the 2 months and 15 days deadline for QSST elections. That seems incredibly short given how complex these situations can be. What happens if you miss that deadline? Is there any way to fix it or are you just stuck with the tax consequences? Also, when you mention coordinating with the estate executor - what specific things should we be asking them about or making sure they handle properly?

Great question about the QSST election deadline! If you miss the 2 months and 15 days deadline, the consequences can be severe - the S-Corp election typically terminates, meaning the corporation gets taxed as a regular C-Corp going forward. However, the IRS does have a relief procedure under Rev. Proc. 2013-30 that allows late QSST elections in certain circumstances, but you need to show reasonable cause for the delay. Regarding coordination with the estate executor, here are the key things to discuss: 1) Make sure they're aware of the QSST election deadline and coordinate timing, 2) Confirm they're getting a qualified business appraisal for the S-Corp shares (needed for both estate tax and your step-up basis), 3) Verify that all required estate tax elections are being made consistently with your tax planning, and 4) Get copies of all estate documents that affect the S-Corp shares since you'll need these for your own tax filings. The executor should also be coordinating with the S-Corp's tax preparer to make sure the company's tax returns properly reflect the ownership change. Don't assume everyone is talking to each other - in my experience, communication gaps between estate attorneys, CPAs, and business advisors are unfortunately common and can create expensive problems later.

This is such an important point about phantom income that I wish more people understood! I inherited a partnership interest a few years ago (different structure but similar tax issues) and got blindsided by a huge K-1 with almost no cash distribution. Had to scramble to pay taxes on income I never actually received. @e702dc8202f6 you're absolutely right about negotiating distribution policies upfront. In my case, the other partners weren't family and had no interest in helping with my tax burden. Ended up having to take out a loan to pay the taxes, which was a nightmare. One question - how do you typically approach the other shareholders about establishing minimum tax distributions when you're the new person coming in? I imagine it can be awkward, especially in a family business where the existing owners might not want to change their cash flow strategy. Do you have any tips for those conversations?

@88ba399ac1bb Great question about navigating those conversations! I've found it helps to frame the discussion around protecting the S-Corp election and maintaining good tax compliance rather than making it about your personal cash flow needs. Here's what I'd recommend: First, come prepared with research showing how other similar S-Corps handle tax distributions - this shows you're being reasonable, not demanding. Second, emphasize that adequate distributions protect ALL shareholders by ensuring everyone can meet their tax obligations and maintain the S-election. Third, consider proposing a graduated approach - maybe start with distributions covering just the tax liability at the highest marginal rate, rather than asking for full cash flow distributions. In family businesses especially, positioning it as "ensuring the business stays compliant and family members aren't financially stressed by the tax burden" tends to work better than "I need cash." You might also suggest having the company's CPA or attorney explain the risks of inadequate distributions to the group - sometimes the message lands better from a neutral third party. If the family is resistant, you could also explore whether there are any existing buy-sell provisions that might give you options, or whether the company would consider a partial redemption of your shares to reduce your ongoing K-1 burden. The key is showing you've thought through multiple solutions, not just presenting the problem.

@687387293767 This is such great advice about documentation and finding the right professional! I'm actually in a similar situation as the original poster - just inherited S-Corp shares through a trust setup and feeling completely overwhelmed by all the requirements. Your point about keeping everything in a dedicated file really resonates. I've been scattered with documents between my attorney, the estate executor, and my current CPA, and I'm realizing I don't have a complete picture of what I actually have. One question - when you mention the IRS paying more attention to step-up basis claims for business interests, are there specific red flags they look for? I want to make sure I'm not inadvertently doing something that triggers extra scrutiny. Also, do you have any suggestions for finding CPAs who actually specialize in S-Corp/trust issues? It seems like a pretty niche area and I'm having trouble finding someone locally who really knows this stuff well. Thanks for sharing your insights - this whole thread has been more helpful than months of trying to figure this out on my own!
