Does it make sense that I owe $600 in federal taxes this year but got a refund of $800 last year? I did make more money in 2021 for my W2 but my tax bracket's the same.

More income = more tax

 

Print out your 2020 and 2021 returns and compare them side by side so you can see what is different for this year.

Usually more income = more tax = less refund.  Your withholding didn't increase enough to cover the tax due.  Or some credits you got are reduced because you made more income.

If your federal refund is lower than expected, it's because you didn't have enough federal income taxes withheld from your paychecks. Do a line by line review of your 2021 Form 1040 versus your 2020 Form 1040 to identify the difference or differences. See How do I preview my TurboTax Online return before filing?.  Also, see the information below. 

• Tip: If your refund is wildly off, you may have mistyped a dollar amount somewhere. An extra digit here, a missing number there, even a misplaced decimal point can have an eye-popping (but easily correctable) effect on your refund.

If you didn't update your form  W-4 for 2021, it’s highly possible this is why you owe. If you'd like to get a bigger refund, complete a form W-4 for 2022 and have an additional withheld. You'll get less money in your paycheck but you'll get a bigger refund next year. 

 

We've got some other possible reasons for a year-over-year refund decrease:

• You had more than one W-2. See Why did my refund drop when I entered a second W-2?
• Changes in your income or tax rate
• State and local income tax deduction changes
• Losing certain credits or deductions

maybe maybe not. wore income more taxes but with a bigger w-2 more withholding.   we can't see your returns so we are guessing
