I was recently lucky enough to see a raise to my paycheck. My gross salary increased by $99.20 — but my take home only went up $27.66. I don’t feel that my tax burden is outrageous and I’m lucky to be able to contribute towards 401(k) and employee stock plans, but you have to wonder where 72% of it goes.
This (and the recent tax deadlines) got me thinking about marginal tax rates and the benefit of earning additional money. Playing around with the numbers for a couple different states, you can estimate the total tax burden. Here is a rough estimate for federal taxes, as well as three states in which I have lived (California, Indiana and Oregon). Numbers assume married filing jointly in 2012, except for California which still uses 2011 rates.
Federal Tax burden
Income Tax
| 10% on income up to $17,400 |
| 15% on income from $17,400 to $70,700 |
| 25% on income from $70,700 to $142,700 |
| 28% on income from $142,700 to $217,450 |
| 33% on income from $217,450 to $388,350 |
| 35% on income above $388,350 |
FICA Witholdings
Besides income tax, there are Social Security and Medicare withholdings on any earned income (salary, but not dividends, capital gains, etc.). In addition to the amount withheld from your paycheck, a matching amount (or more) is provided by the employer.
| 4.2% of your salary is withheld on the first $110,100 of income, and your employer contributes 6.2% (again, only on the first $110,100 of income per person). |
| 1.45% of your salary is withheld and your employer contributes an additional 1.45% of your salary. |
| Combined, these work out to 13.3% of your salary up to $110,100 and 2.9% of your salary above $110,100. |
Example
This means that a hypotetical couple making $220,200 ($110,100, each) would be paying a marginal tax rate of 38.65% on their last dollar (and their employer would also be contributing 7.65% in FICA taxes). If they make $388,350, this would actually be a marginal tax rate of “only” 34.45% (and their employer would contribute 1.45% of that last dollar), as they will have maxed out their social security contributions.
Note that marginal tax rate is very different from total tax rate. In these examples, the $220,200 couple would have paid $62,013.80 in federal income/FICA taxes (and their employers, $16,845.30), while the $388,350 couple would have paid $119,941.48 in federal income/FICA taxes (and their employers $19,283.48). This works out to an effective tax rate of 35.81% and 35.85%, respectively. So the higher earning family does pay a higher overall tax rate, but not by much.
[Note that these incomes were chosen because of the impact they have from FICA deductions. $220,200 is the least a couple could make and max out their Social Security contributions. $388,350 is the most a couple can make, maxing out Social Security but not entering the 35% federal tax bracket. Perhaps later I can update the calculations with more reasonable income values.]
State Tax burden
Income Tax
Not every state collects income tax on ordinary income (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming are the ones that don’t). For the states in which I’ve personally lived, the tax rates vary quite a bit.
| California | Indiana | Oregon |
| 1% on all income up to $14,632 | 3.4% on all income | 8.132% on income up to $50,000 |
| 2% on income between $14,632 and $34,692 | (Counties in Indiana typically collect as well, for example Hendricks County collects 1.4% on all income) | 9% on income from $50,000 to $250,000 |
| 4% on income between $34,692 and $54,754 | 9.9% on income above $250,000 | |
| 6% on income between $54,754 and $76,008 | ||
| 8% on income between $76,008 and $96,058 | ||
| 9.3% on income between 96,058 and $2,000,000 | ||
| 10.3% on income above $2,000,000 |
Sales Tax
Not every state collects sales tax (Alaska, Delaware, Montana, New Hampshire, and Oregon do not). Sales tax is very different from income tax in that it only affects money that you spend. So someone who is saving for retirement should worry more about income tax and less about sales tax (since they should be earning more than they spend) while someone who is retired may worry more about sales tax than income tax (since they may be spending more than they earn).
| California | Indiana | Oregon |
| 7.25% | 7% | 0% |
| Cities/Counties in CA may charge more. For example, San Diego charges 7.75% total |
Example
Using our earlier examples, we can estimate the state tax burden of the couples listed above. For sales tax estimates, I am assuming that they spend 100% of their post-tax income, which isn’t a good idea, but may represent the typical consumer more than I would like.
For the couple earning $220,200, they would pay income taxes of $15,774 to California, $7,486.80 to Indiana (plus $3,082.80 to Hendricks County), and $19,384 to Oregon. Assuming they spent everything left after federal and state taxes, they would pay an additional to $10,324.88 in California sales tax ($11,036.95 in San Diego), $10,333.16 in Indiana sales tax, and $0 in Oregon Sales tax. It’s interesting to note that you may pay more in Indiana sales tax (at 7%) than California sales tax (at 7.25%). This is because there is more income remaining to spend in Indiana, after income tax is withheld.
For the couple earning $388,350, the tax burden would look like the following. In California, they would pay $31,412 in income tax; in Indiana, $13,203.90 (plus $5,436.90 to Hendricks County); in Oregon, $35,762.65. The sales tax burden would be up to $17,182.25 for California ($18,367.23 in San Diego), $17,483.74 in Indiana, and $0 in Oregon.
Summary
Taking all of this data, and trying to consolidate it into specific comparisons, we can gauge the relative expense of the three states.
| CA (San Diego) – $220,200 | IN (Hendricks) – $220,200 | OR – $220,200 | |
| Federal Income Tax | $49,572.50 | $49,572.50 | $49,572.50 |
| Personal FICA | $12,441.30 | $12,441.30 | $12,441.30 |
| Employer FICA | $16,845.30 | $16,845.30 | $16,845.30 |
| State/County Income Tax | $15,774 | $10,569.60 | $19,384 |
| Spending (after income/FICA) | $142,412.20 | $147,616.60 | $138,802.20 |
| Sales Tax | $11,036.95 | $10,333.16 | $0 |
| Total Tax Burden | $105,670.05 | 99,761.86 | $98,243.10 |
| Total Tax Rate | 47.99% | 45.31% | 44.62% |
| CA (San Diego) – $388,350 | IN (Hendricks) – $388,350 | OR – $388,350 | |
| Federal Income Tax | $105,062.00 | $105,062.00 | $105,062.00 |
| Personal FICA | $14,879.48 | $14,879.48 | $14,879.48 |
| Employer FICA | $19,283.48 | $19,283.48 | $19,283.48 |
| State/County Income Tax | $31,412.00 | $18,640.80 | $35,762.65 |
| Spending (after income/FICA) | $236,996.52 | $249,767.72 | $232,645.87 |
| Sales Tax | $18,367.23 | $17,483.74 | $0 |
| Total Tax Burden | $189,004.19 | $175,349.50 | $174,987.61 |
| Total Tax Rate | 48.67% | 45.15% | 45.06% |
As you can see, the state in which you live can make a significant difference to your tax burden. In this comparison, Oregon has consistently higher tax rates that look the worst, up until sales tax is included. Once that is taken into account, it actually becomes the lowest tax burden in these examples. Of course, that will change based upon income level. One other item of interest is that, due to Indiana’s flat tax system and the phase-out of the Social Security tax, a couple in that state earning $220,200 actually pays a slightly higher percentage of their salary in taxes than a similar couple earning $388,350!
Unfortunately, these are just estimates and doesn’t reflect the full tax calculation. I have oversimplified the tax calculations in several ways, but I feel that many of these simplifications lead to offsetting errors. For example, I’ve ignored that state income tax is typically deductible on your federal taxes and not all purchases are subject to sales tax, leading to an overstated tax burden; however, I’ve also ignored Alternate Minimum Tax, property taxes, gasoline taxes, car registration, and alcohol/tobacco taxes, causing this to understate your total tax liability.
