My objection is that these are on unrealized capital gains. Once the tax is paid, the money is gone gone gone.
No, the money is not gone.
What happens if the value of the asset drops?
Then you get the loss back as a reduction in taxes owed or as a refund.
What if there are losses? Will the IRS reimburse?
Yes.
Not guessing on this one. One of the current permitted tax keeping and valuation procedures (rarely used, but nonetheless recognized as valid by the IRS) is the proposed “market value” of assets. As long as the system is maintained consistently over the tax years–and taxes paid/losses reported–based on “market value” at a consistent time period every year, the IRS will accept the return as valid. The key point is best-reasonable valuation of the assets each year. Once that is is done and accepted, the rest is just filling in the paperwork with the numbers by doing the arithmetic.
This system is more difficult for large businesses but much simplef for small businesses that have inventory that varies in value wildly over time (think seasonal/holiday items). Especially true when much inventory turns over very quickly–so whatever is “left over” has no or very minimal value. Typically, a small business will use cash-basis accounting, so few problems with “market value” analysis because the cash system automatically sets all inventory on hand to zero (because the “cash out” to buy ALL the inventory is an expense but there is NOT [on tax records day] a total sale of all the inventory). When the carried-over inventory is sold, the revenue is all profit because it was sold for cash (with a cost of zero) because that cost was written off some prior year when it was purchased.
