Calculators

Each one runs on the same published figures as the guides, so a result and the writing around it can never disagree.

What TopicDrill is

TopicDrill is an independent reference for US personal and small-business finance. We publish the numbers that govern everyday money decisions (tax brackets, withholding rates, contribution limits, minimum wage, sales and property tax) for all fifty states and the District of Columbia, and we say where each figure came from and when it took effect.

Questions about TopicDrill

What does TopicDrill do?

We publish the figures that govern US money decisions (federal and state tax rates, withholding, contribution limits, minimum wage, sales and property tax) with the source and effective date attached to every one, plus calculators built on the same data.

Where do your numbers come from?

Federal figures come from the IRS and the Social Security Administration. State tax rates come from the Tax Foundation and state revenue departments; minimum wage comes from the US Department of Labor. Each figure carries its source on the page it appears.

How often are the figures updated?

Most change on 1 January, when new tax years and state minimum wages take effect, with a second wave on 1 July. We re-check a figure whenever its source republishes, and every page shows the date it was last updated.

Is TopicDrill a government website?

No. We are an independent publisher. We cite government sources and link to them directly, but we are not affiliated with the IRS, the SSA, the Department of Labor or any state agency.

Is this tax advice?

No. This is general information. Rules change and individual circumstances vary, so check with a licensed tax professional before acting on anything you read here.

How do you make money?

Through advertising and affiliate commissions when a reader uses a link to a product we recommend. Commissions never affect which products we recommend or how we rank them, and any page containing affiliate links discloses that above the article.

Can I cite or quote TopicDrill?

Yes. Quote what you need and link to the page it came from. Our data policy and citation terms are published at /llms.txt for automated readers.

How do the calculators work?

Each calculator reads the same sourced figures we publish in our articles, so results stay consistent with the written guidance. Tools with state variants load that jurisdiction’s own rates.
