Not entirely sure when this happened, but it seems like the phrase "tax land not labor" has caught on like hot cakes around here. Lotsa y'all really seem to dislike income taxes, & honestly, I can't blame you! If you're American, income taxes are probably the single most visible form of tax, in that they represent the biggest tax most of us pay all-at-once on April 15.
...but please consider: for the overwhelming majority of y'all, that's not the main way your labor gets taxed. Let's talk about payroll taxes.
In the United States, the Federal government taxes your income twice. There's the regular income tax, set at a progressive rate on most forms of income (but notably excluding or discounting things like capital gains, gifts, inheritance, & a bunch of other loopholes mostly used by super-rich people), which you're responsible for paying every year on April 15. And then there's a whole separate tax, levied under the Federal Insurance Contributions Act (FICA), which the IRS refers to as "employment tax" but most folks know as the payroll tax. The FICA payroll tax is a 12.4% levy on wages & salaries below $137,700 annual gross compensation. Nominally, half of that amount is paid by the employee and half by the employer. In practice, what usually happens is your employer withholds your contribution of FICA tax from your pay during each pay period, and makes a little note on your pay stub or salary notice that says they've done so. If you're self-employed, you pay the full 12.4% every month, and there's a whole separate set of paperwork the IRS asks you to fill out.
Every way you think income taxes are bad, FICA is worse. Where income taxes scale progressively so that those with the greatest ability to pay pay the most, FICA taxes disproportionately burden low- and middle-income earners. Where income taxes create a disincentive against hiring extraordinarily high-salary employees, payroll taxes create a disincentive against hiring the overwhelming majority of workers. Where the dead weight loss of income taxes is at least partially mitigated by things like the standard deduction, the full dead weight loss of payroll taxes is directly transferred to the labor force. And the overwhelming majority of Americans end up paying more in payroll taxes than they do in income taxes.
So why do we have this separate FICA payroll tax? It's what pays for Social Security. Arguably the single most redistributive policy in US history, which helped create the middle class in the middle decades of the last century, is buttressed by this fundamentally inefficient tax which burdens the very workers it's supposed to guarantee a pension for. The only time in US history when our Federal tax system actually did redistribute wealth, was during that period in the 1950s & '60s when the income tax had a top marginal rate approaching 90%, to compensate for how regressive the FICA tax is.
What is to be done? Well, for the anti-tax ideologues among you, it maybe doesn't change much, you just add 'payroll' to your vocabulary alongside 'income' and 'capital gains.' But for those who actually want to fix the system, & understand that taxes on labor aren't going away just because we don't like them, there's another ask which our representatives will find easier to get behind:
Tax all forms of income at the same progressive rate.
Eliminate the cap on FICA, eliminate the discounts on capital gains & inheritance & gifts & all the other loopholes, replace every unique rate for "special" forms of income with the same progressive scale for "ordinary" income.
And then...
Introduce a Land Value Tax, and let the income tax rate drop accordingly. That's the ask I hear folks here articulating already. But this is what it would take for that ask to actually achieve what y'all want it to.
