I recently started work at a small company - I'm the sole employee along with the business owner. For my retirement benefit, he will begin contributing 25% of my salary into a SEP IRA after 2 years of employment. While this is an amazing perk compared to the 4% 401k matching I'm accustomed to, my tax-advantaged savings are currently limited to the 6k in my IRA. My boss and I have a great relationship, and I'm considering this proposition to bridge that 2 year gap:
In order to get some money set-aside in a pre-tax account, I'm wondering if I could forgo a portion of my salary in order to get the IRA contribution immediately. In practice, I would take a 25% salary cut on my W2, and my company would contribute that amount into the SEP IRA account. I don't see a negative from my end, as this is money I would otherwise be saving in a brokerage account. I don't see why my employer would mind, aside from a little leg-work to adjust my paycheck/tax withholdings. Once I hit the 2 year anniversary, my salary would return to "normal" and the 25% IRA contributions continue depositing.
Is there a reason that either my employer or I would want to avoid this? Are there tax implications that I'm not considering?
