Just anecdotally, when @rantk81 mentioned cliffs, the number that jumped to mind when I started noticing it was about 140k (MFJ). You're beyond the heavily redistributive benefits (WIC, Medicaid, rental assistance, etcetera), and you've hit the phase out on the middle class deductions/benefits (student loan interest and the third stimulus come to mind, along with some local property tax refunds), but you don't make enough or have enough assets to engage in long term structural tax avoidance.
There are a couple sides to this. Obviously you aren't getting aid, but iirc ss tax caps at $125k so some benefit there. Another thing you missed is that you get boned on Roth IRA above a certain income.
or have enough assets to engage in long term structural tax avoidance.
You can have plenty of assets at 140k income, that's pretty much the point of this blog. What sort of tax avoidance are you thinking is only available at higher net worth though? Please be specific as I'd like to avoid taxes.
To the questions above:
For 2022, Social Security applies to $147k per earner.
In very high earning areas, compensation itself is often structured to minimize rather than maximize W2 income. Other ways of being compensated are stock or deferred compensation plans. At $200k, not very many HR departments are thinking about how to make the number on their employees paychecks lower, but at $600k they often are.
As to the "not enough assets" comment, yes, it's possible to report low W2 income while having high assets. But at some point you have to accumulate those assets, and unless you inherit them, usually that will involve reporting them as income.
Most of the higher net worth strategies involve businesses, real property, and/or intergenerational transfers. Turn your personal property into business property, then pass it back to your heirs as personal property tax free. Or, perhaps more commonly, start a business and treat as many personal expenses as possible as business expenses. Vehicle leases? Business. House? Owned by a shell property company and leased 75% to the business and 25% to the family. Vacation home? Also a business property that's leased on a nightly basis to the family. Oh, and you can launder these "business" assets $15k/year tax free to every child and grandchild.
One of the disadvantages to holding all or most of your net worth in tax advantaged accounts is that this sort of tax avoidance is more difficult.
