We recently met with our 401K providers and as a plan administrator and part owner of the business I have control over employer contributions. I'm also fortunate enough to earn a bonus at the end of each year. Due to safe harbor rules I will be able to make a sizable employer contribution to my 401K account (essentially in exchange for a chunk of the bonus) to reduce my AGI substantially, which reduces the taxes I'll pay on this bonus down to $0.
I just ran this through my year end bonus, tax, and net worth spreadsheets and project approximately $7K/year in increased net worth. I realize this puts funds into a tax deferred vehicle and I'll pay tax upon withdrawal, but since I plan to implement a Roth pipeline 20 years before normal retirement age I hope to keep those taxes extremely low. They will certainly be much lower than my current calculated effective rate on the last dollar of earnings.
This wouldn't have happened without learning these tricks via this forum, the MMM website, and other PF bloggers, so I'm really sharing the badassity of this entire community. It's good to be an insider into this world, and to be able understand and implement these strategies.
Thank you all for sharing your knowledge.
