Tax expenditures, which are essentially government spending through the tax code, primarily benefit higher-income households and corporations, though some, like the EITC and Child Tax Credit, are specifically designed to help lower-income families. Deductions for things like mortgage interest, state/local taxes (SALT), and retirement plans heavily favor the wealthy, while refundable credits like the Earned Income Tax Credit (EITC) go to the working poor, showing varied impacts depending on the specific provision.
Overall, higher-income households enjoy greater benefits, in dollar terms, from the major income and payroll tax expenditures.
In general, taxpayers only benefit from itemizing their deductions if their itemizable expenses are greater than the standard deduction amount. Because high-income individuals generally have the highest itemizable expenses, they are more likely than other taxpayers to itemize their deductions.

Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.
It makes sense to itemize deductions when the total of your specific expenses (like mortgage interest, property taxes, charitable donations, and certain medical costs) is greater than the Standard Deduction for your filing status, as this lowers your taxable income more significantly. You might also be required to itemize if you're married filing separately and your spouse itemizes, or if you file as a trust, estate, or nonresident alien.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.

The IRS doesn't have a specific dollar limit for hobby income; instead, it focuses on profit motive: if you intend to make a profit, it's a business, but if it's for fun, it's a hobby, and you must report all income but can't deduct losses. Key is that you report all hobby income on Form 1040 as "other income," and if net earnings from self-employment are $400 or more, you owe self-employment tax, even if it's a side gig. The main difference from business is that you can't deduct hobby expenses (under current law) and must report all profits.
