How does paycheck withholding actually work?

Fri, 21 Aug 2026 13:20:00 -0400

Paycheck withholding is an estimate, not the tax. Form W-4 tells the employer how to treat this employee in the payroll tables. Publication 15-T is the set of methods and tables the employer uses. The year’s actual income tax is figured later on Form 1040. Withholding that already went to the Treasury is a credit on that return.

What is the difference between a money market fund and a high-yield savings account?

Fri, 21 Aug 2026 13:10:00 -0400

A high-yield savings account is a bank deposit. A money market fund is a mutual fund. The names sit near each other on a rate table. The legal objects do not. One is a claim on an insured depository institution. The other is shares in an SEC-regulated investment company that holds short-term debt.

How does FedNow actually differ from ACH?

Fri, 21 Aug 2026 13:00:00 -0400

FedNow and ACH are different rails. ACH is a batch messaging network. Banks send files of credits and debits to an operator, which sorts them and settles on banking days. FedNow is an instant payment service the Federal Reserve Banks operate: one customer credit at a time, any day of the year, with settlement that is final when the Reserve Banks record it. One does not replace the other.

What is the difference between a US tax credit and a tax deduction?

Fri, 21 Aug 2026 00:50:00 -0400

A tax credit cuts the tax itself. A tax deduction cuts the income the tax is calculated on. Same dollar amount, different line, different result. One is a subtraction from the bill. The other is a subtraction from the number the bill is based on.

How does an index fund actually own the stocks in an index?

Fri, 21 Aug 2026 00:40:00 -0400

An index fund does not own “the index.” An index is a list and a weighting rule. The fund is a pooled company that buys some or all of the securities on that list. You own shares of the fund. Those shares are a claim on the fund’s portfolio, not stock certificates with your name on them.

How does ACH actually move money between US bank accounts?

Fri, 21 Aug 2026 00:30:00 -0400

ACH does not ship cash from one vault to another. It is a batch messaging network. Your bank, or the other bank, sends a file of credits and debits to an operator — the Federal Reserve or The Clearing House. The operator sorts the file, delivers the items, and settles by moving balances in the banks’ own accounts.
