I doubt you’re going to find what you’re looking for. But it isn’t very hard for you to figure it out for yourself.
The tax tables in the back of the 1040 instructions give the federal bite from your AGI for values from zero to $100K/yr. That’s as close as you’re likely to get except from some tax protest source where you can’t trust the figures.
Because of the huge potential differences in deductions, it isn’t generally possible to say “$55K gross will pay $18K (or whatever) in federal taxes.” For $55K gross, the AGI could be zero or it could be about $50K, depending on your deductions.
As to state/county/city income taxes, those vary from zero to about 10% of income dcepending on where you live. That’s a non-trivial impact on your post-tax bottom line.
As to sales tax, personal property tax, real estate tax, etc., those taxes depend entirely on your lifestyle.
If you earn $55K/yr and rent an apartment/house, never eat out, own one set of clothes, take the bus to work, and save the rest, then your tax expenses after income tax would be approximately zero.
OTOH, if you always eat out, buy a new car often and lots of new clothes & other consumer stuff, save nothing, and spend very little on housing or groceries (live with parents?), then virtually 100% of your take-home pay would be subject to sales tax.
Those two extreme scenarios give a 6-9% difference in tax bite depending on locale.
If you just want a worst-case number, that’s not too hard. Let’s assume 100% of the income is ordinary W2 wages from a job or jobs, or from simple investments (buy-and-hold mutual funds, bank accounts, etc) and that you’re single. You rent your living quarters or own a small condo/house with a small mortgage.
- Take the gross income.
- Subtract 7.65% from step 1’s value for Social Security/Medicare.
- Subtract $7800 from step 2’s value for the standard deduction and single exemption.
- Use the 1040 tax tables (available from www.irs.gov as a pdf) to figure the tax on step 3’s value. Subtract that from step 2’s value.
Now we’ve covered federal tax bite.
-
Subtract 0%, 5%, or 10% from step 4’s value for state tax. Use 0% if your state has no income tax, 10% if you live in NY, CA, or one the the other extra-heavy tax states, 5% otherwise.
-
Subtract 5% from step 5’s result for all other taxes (sales, real estate, personal property, etc.). 5% is a wag because although most tax rates are higher, not all of the money you earn will be spent in taxable transactions.
That’s the bottom line.
For $55K gross in a typical state tax situation that becomes:
- $55000
- 55000 - 4208 = 50792
- 50792 - 7800 = 42992
- 42992 - 7554 = 35438
- 35438 - 1772 = 33666
- 33666 - 1683 = 31983
Taa-Daa. 42% in taxes, 58% for you.
OTOH, if we eliminated all the taxes you’d get a bill every month from the Highway Dept (fed and state), the Army, the Police Dept (state and local), the Fire Dept, the FBI, the Attorney General (Fed and state, plus the local DA), the Bureau of Prisons, the EPA, the FAA, the FDA, the Consumer Affairs bureau, the Forestry Service, the Coast Guard, etc.
It’s kinda convenient to be able to pay all those bills with just a couple of (big) checks. Think of all the postage you save this way.
You can also see it’d be easy to create a spreadsheet for each step except the Fed tax table. Fortunately there’s also a formula for computing the tax, so you could put that into the spreadsheet easily enough. See page 74 of the 2003 IRS 1040 instructions for details.
Once you’ve built the spreadsheet you can make the table you’re looking for.
Also, as I said, that is pretty much worst case. If you’re married and/or have kids and/or have a big mortgage and/or lots of investment income or losses and/or you’re self-employed and/or … well then the tax bite is somewhat less.
And, because Fed income taxes are progressive, the bite is worse as a percentage as you make more, and less if you make less. The same is true of state income taxes, which I ignored. You can fudge that by adding/subtracting 1% for incomes below $20K or above $100K.
