An HSA contribution of $7,300 will reduce your Adjusted Gross Income (AGI) by $7,300. But it does not reduce your tax by $7,300. The reduction in your tax depends on what tax bracket your income is in. If you are in the 22% tax bracket, a $7,300 reduction of your AGI will reduce your tax by $1,606 (22% of $7,300).
A change in AGI can have "side effects." It might increase or reduce certain other deductions or credits. So depending on what else is in your tax return, the change in the tax might not be the exact tax bracket percentage.
When you make the HSA contribution, be sure to tell the HSA trustee clearly that it is a 2022 contribution. Otherwise they will assume that it's for 2023.
If you have further questions, please give exact amounts, not rounded or approximate.
