457 contribution confusion
My employer is changing paid time off policies so that we can no longer accrue banks of time. As such, they are paying out the time to employees. I opted to have my payment deferred through a 457. I understand the basic mechanics of a 457 but don't understand how the taxes withdrawn will affect future taxes (this just happened and I won't get any W2 until this time next year); basically I think something is amiss. My example is below with hypothetical amounts just for illustration.
My deferred compensation (PTO) $10,000
social security and medicare taxes withheld $100 (again, not the actual, just illustrative)
income tax withheld $1,000
amount deposited into my pre-tax 457 $8,900
Here's my confusion. I understand that sick time payouts are subject to social security and medicare in the year the income is earned because of special rules. But, I thought the income tax would be deferred until I withdraw from this account.
My employer has said not to worry as I'll be refunded the $1,000 income tax. But this causes two issues: 1. my 457 account loses $1,000 and 2. wouldn't that $1,000 then technically be income that I would be taxed on next year? The payroll processor provided a lengthy email that was just said they have no way to process SSI and medicare taxes separate from income tax on income. None of this makes sense to me and I'm a bit concerned about how this will affect my taxes next year.
Any thoughts?
