Just in case anyone is curious about how it works...

Your entire income isn't taxed at the same rate. Each chunk of your income is taxed differently. The first 11k is taxed at 10%, the next 35k is taxed at 12%, the next 50k is taxed at 22%, and it continues on at different intervals after that. This person believed that going from 44k to 45k would then change their tax bracket and their gross income would be taxed at 22%, thus reducing their net income. This is false. Only the amount over the threshold gets taxed at the higher rate. Always take a raise if it benefits you.

This legit happened to a college of mine, at his first job (as engineer), it took me well into his second year of employment (the time when he got the second yearly income tax stats) to get him to understand what I've been explaining to him since he was offered a raise a few months after he started.

I tried, I really did, with charts, examples, my own income tax statement, ... but no.

I never found out which part was bothering him, like theoretically, how tf ...

I'm a tax accountant.

You'll never make less due to income tax for making more money.

You can start to get certain credits phased out and can become subject to things like the Medicare surcharge.

But it's still unlikely that making more will ever get you less.

In a similar track though, I refused raises for a couple years because my kid was in college. If I got a raise, I would be kicked into the next income tier of financial aid eligibility, and that could've been catastrophic. Those lines don't seem to phase as much as they seem to be hard cutoffs - at least as far as my kid's specific school was concerned. All of her financial aid (grants, not loans) came directly from the school, not the government.

I also was able to enjoy a little bit of education expense credit on my tax return because if it, but that part was nominal.

The biggest hit has been going from head of household with a dependent tax credit to single with fuck all credits. Fortunately, I can itemize my way into a deduction midway between single and head of household, so I got that going for me, which is nice.

Edit: Wow, that was a gibberish filled gummy induced wall of text. Nothing particularly factually incorrect, but man what a slew of non sequitur.

It's comparatively unlikely, but there are circumstances where this type of thing can be true. Because income tax is not the only factor that matters. For example, you might get put on too high an income to qualify for some sort of tax rebate or welfare programme. Or you might start qualifying for an additional tax that isn't applied marginally.

As one specific example, in Australia we have the Medicare Levy Surcharge, which you pay if your income is above a certain threshold and you're above a certain age and don't have private health insurance. If those conditions are met, it applies to all your income. It's a small enough surcharge (ranging from 0% to 1.5%, with 1% and 1.25% steps in non-marginal brackets in between) that there are almost no practical circumstances that you'd actually end up worse off taking a raise, but it is at least theoretically possible.

You guys are getting paid?

Amateurs.

Hate getting bumped up into the 125% tax bracket

I took a 50% pay cut and my partner took a job that paid 10% less than her previous job but we moved somewhere that we got a 500k house on 1+ acre of land instead of our 800k townhouse, no land with one parking spot.

Sometimes less is more.

someone failed at teaching this loser mathematics.
