I recently changed employment and have securities in my former employer's 401(k) plan.
The cash component of the 401(k) I am rolling over into an SEP-IRA.
What I need advice on is whether I should also rollover the securities in the 401(k) plan.
The issue is that taking money (eventually) out of the 401(k) plan will be taxed as income (at a marginal rate of 28%). However, cashing out now will incur capital gains tax (15%) as well as an early withdrawal penalty (10%).
This difference (28% vs 25% with the numbers above) is the problem. This issue is often referred to as the Net Unrealized Appreciation or NUA.
I've found some calculators here and here which (purport to) show the advantages of one approach versus the other.
What other aspects of the issue should I take into account, assuming that the cash-out option shows the better monetary return?
