Tax Table
  
That large, wooden piece of furniture, carved with the druidical runes, where you like to do your taxes. You think the wood nymph energy helps lower the tax burden.
Actually, in this case, we're talking "table," like...on a spreadsheet. Not a physical table. Still, wood nymph energy can't hurt.
The tax table is a listing of various tax rates for different levels of income. The IRS publishes it as part of the instructions for filling out tax returns. They give a graphic presentation of levels of incomes and corresponding tax rates. That way, people can determine the rate they should use to determine their tax liability.
Or you can just use software. Or, better yet, splurge a little and hire an accountant. Use the time saved to go on a hike or something. It's April, after all. Spring is here. Get out of the house, get into nature, commune with the wood nymphs the old-fashioned way: running naked through the forest. Better than sitting at your tax table hunched over the W-2s.
