@sasho1987 - no...because HSA cotnributions are not taxed for SS and Medicare
Box 1 is already reduced by HSA and 401K
Box 3 is already reduced by HSA only - this box has no bearing on your tax return in any event.
Don't forget the employee share of health insurance premiums, employer-provided parking, and some other less common tax-advantaged employee benefits.
If you are trying to "create" a W-2 because you didn't get one, it would be better to start with all the facts and work forward, instead of trying to work backwards.
If you are trying to estimate your future tax bill, then your box 1 taxable income is your wages minus pre-tax employee benefits. Some pre-tax benefits are also subtracted from box 3 and box 5, but other benefits are only subtracted from box 1, and we would need more details if you want a precise figure. (Box 3 also has a maximum value of $147,000 for 2022, even if you earn more, you only pay SS tax on the first $147,000.)
