What is box 33 on a tax return?

Editorial team Published on

Box 33 on the standard medical insurance claim form (CMS-1500) reports the billing provider's name, address, phone number, and NPI number to direct insurance reimbursement.

🔎 Overview of Box 33

  • 📌 Purpose: Identifies the exact entity or organization requesting payment for medical services.
  • 📌 Key Sub-fields:
    • Box 33: Billing provider's physical address, name, and telephone number.
    • Box 33a: The provider's National Provider Identifier (NPI).
    • Box 33b: Additional taxonomy codes or secondary payer-assigned identifiers if required.

(Note: If you are looking at a specialized employer or agency document like a USPS W-2 counterpart, Box 33 can occasionally designate "Taxable Employee Business Expenses", but on general healthcare/insurance claim documents, it strictly refers to billing provider details).

Which billionaires paid no federal taxes?

Leaked ProPublica Internal Revenue Service (IRS) data showed that several prominent billionaires paid $0 in federal income taxes in specific years.

  • Jeff Bezos: Paid zero federal income taxes in 2007 and 2011.
  • Elon Musk: Paid zero federal income taxes in 2018.
  • Michael Bloomberg: Paid zero in multiple recent years.
  • George Soros: Paid zero for three consecutive years.
  • Carl Icahn: Paid zero in two separate years.

How They Pay Zero Tax

  • Low Wages: Wealthiest individuals often take very small direct salaries (e.g., a $1 salary).
  • Unrealized Gains: Most of their wealth is tied up in stock, which is not taxed until sold.
  • Borrowing Against Assets: They fund personal lifestyles and purchases by taking low-interest loans using stock as collateral, which avoids triggering capital gains.
  • Deductions: Investment losses, interest deductions on loans, and charitable donations offset what little taxable income they report.

What is the most overlooked tax deduction?

State and local sales taxes (instead of state income taxes) and out-of-pocket charitable expenses are widely considered among the most frequently missed tax breaks by filers.

Because tax software and standard checklists often focus on big-ticket items like mortgages and major cash donations, smaller or flexible write-offs slip through the cracks. Review the most commonly overlooked deductions below to see if you qualify.

Top Overlooked Deductions

  • State Sales Tax vs. Income Tax: You can choose to deduct either your state and local income taxes or your state and local general sales taxes. This is especially helpful if you live in a state with no income tax (like Florida or Texas) or if you made a major purchase like a car or boat during the year.
  • Out-of-Pocket Charitable Contributions: Cash donations get all the attention, but non-cash items (like clothing or household goods given to charity) and the standard mileage rate for driving to volunteer work are fully deductible.
  • State Income Taxes Owed from Prior Year: If you paid additional state income tax when you filed your previous year's state return, that extra amount paid can often be deducted on your federal return for the year you actually paid it.
  • Reimbursements and Premiums for Self-Employed: If you are self-employed, you might forget to write off health insurance premiums, qualified Medicare premiums, or standard mileage for business trips that weren't tracked through a formal payroll.
  • Out-of-Pocket Classroom Expenses: Eligible educators can deduct unreimbursed expenses for books, supplies, and equipment used in the classroom.

  • Family Status: You may qualify if you have children or dependents, such as through the Child Tax Credit.
  • Life Events & Expenses: Paying for higher education, adopting a child, or buying marketplace health insurance can make you eligible.

Does Taylor Swift pay her taxes?

Yes, Taylor Swift pays her required taxes like federal income taxes and local property taxes, and her massive concert tours also generate millions in public tax revenue.

How and Where She Pays Taxes

  • Federal & State Taxes: Because her official legal residence (domicile) is in Nashville, Tennessee, she files taxes based on federal guidelines and state rules. While Tennessee does not have a personal income tax, she is subject to federal income taxes on her worldwide earnings.
  • Tour Tax Contributions: Her concert stops generate tens of millions of dollars in state income, local sales, and hotel occupancy taxes for cities across the United States and worldwide.

Property Taxes and Legal Write-Offs

  • Property Holdings: She owns multiple high-value properties in places like New York, California, and Rhode Island, making her subject to local real estate and property taxes.
  • The "Taylor Swift Tax": Rhode Island enacted a non-owner-occupied property tax (widely nicknamed the Taylor Swift Tax by media outlets) that specifically targets high-end vacation homes worth over $1 million that sit vacant for most of the year. This added roughly $136,000 annually to the property tax bill for her Watch Hill mansion.
  • Legal Reductions: Like many high-net-worth individuals and businesses, she uses legal strategies to minimize her tax burden—such as utilizing historic landmark status (like the Mills Act for her Beverly Hills estate) to lower property tax liabilities, along with standard business and charitable deductions [0.6.2, Why Taylor Swift and Other Celebrities Pay Less in Taxes Than..., 0.6.8].

Who pays 90% of all taxes?

The top 25% to 50% of U.S. income earners pay roughly 90% or more of all federal individual income taxes.

According to data from the Tax Foundation and IRS records, the tax burden is distributed as follows:

  • Top 50% of Earners: This group pays about 97% to 98% of all federal individual income taxes.
  • Top 25% of Earners: This bracket covers about 87% to 89% of all federal income taxes.
  • Bottom 50% of Earners: This group accounts for roughly 2% to 3% of total federal income taxes paid, as many in this tier have zero tax liability due to standard deductions and tax credits.

Keep in mind that these statistics apply specifically to federal individual income taxes. When including other types of taxes—such as regressive state and local sales taxes, property taxes, and federal payroll taxes—the overall distribution across all income levels becomes somewhat more balanced, though still progressive at the top.

  • Income protection insurance: Premiums paid for policies that protect against loss of income are deductible if you pay for them outside of your superannuation fund.
  • Tax agent fees: The fee you paid to a registered accountant or agent to prepare your previous tax return can be claimed as a deduction in your current return.
