Especially if something's wrong. Tax rates change, states restructure their brackets mid-year, and a corrected number helps everyone who uses this next.

Reporting a wrong rate

This is the most useful thing you can send. To make it quick to fix, include:

• The state, and the county or city if it's a local rate
• What the tool showed, and what it should be
• Where you're getting the correct figure — ideally a state revenue department page

Corrections sourced to a state's own published schedule get fixed fastest, because that's what the tool is built from. Third-party calculator sites frequently disagree with each other and with the states themselves.

Other things worth writing about

• A state that behaves oddly. Several have phase-outs, recaptures, or surcharges that are only partly modelled, and each is noted in the tool. If one is off by more than a rounding error, I want to know.
• A missing input. If your offer has something the tool can't represent, describe it.
• It didn't match your paycheck. Tell me the gap and roughly where you are. You don't need to send real salary figures — a percentage is plenty.
• Sponsorship. If you run something genuinely useful to people weighing job offers, say so plainly and I'll take a look.

What not to send

Please don't send your actual offer letters, pay stubs, or account details. I don't need them and I don't want to be holding them. A description of the problem is always enough.

I also can't give personal tax or financial advice. I'm not an accountant or an advisor, and a question about your specific situation is better answered by someone who is.
