We want to structure our business sale as an installment sale under Section 453 to defer our capital gains tax, but we are worried about the interest charge on deferred tax liabilities if our transaction exceeds the five million dollar threshold. How do we navigate this?

An installment sale is an excellent tax-planning tool under Section 453, allowing you to defer capital gains tax by receiving payments over multiple tax years. However, if the face value of your installment obligations outstanding at the end of the tax year exceeds five million dollars, you face an annual interest charge on the deferred tax liability. To manage this exposure, you must look closely at your entity structure and the allocation of the transaction proceeds. If you have multiple shareholders, the five-million-dollar threshold applies on a per-taxpayer basis, not a per-transaction basis. This means a partnership or an S corporation with three equal partners can support up to fifteen million dollars in installment notes before triggering the interest charge, provided the notes are distributed to the individual partners. Additionally, you should work with your advisory team to allocate a portion of the transaction value to non-installment components, such as immediate cash at close, personal goodwill, or employment agreements for key executives. Ensure your leadership team uses your quarterly Rocks to prepare all financial statements and tax structures well ahead of the letter of intent. By cleanly separating the assets and utilizing individual shareholder thresholds, you can maximize your tax deferral benefits while keeping your interest exposure to an absolute minimum.
