Did you know a single 401(k) can hold three completely different types of money?
• Pre-tax contributions (taxed on every dollar withdrawn)
• Roth 401(k) (tax-free)
• Voluntary after-tax (the backbone of the mega backdoor Roth)
A $600,000 balance might be $350K pre-tax, $150K Roth, and $100K after-tax. Splitting it 50/50 without knowing which buckets each person gets could mean one spouse walks away with mostly taxable dollars and the other with mostly tax-free.
One number. Three very different outcomes.
