Kintsugi Notice Hub

Got a tax notice? Here's what it means

Plain-English explanations of the sales tax and VAT notices businesses get most, by US state and for the UK, with links to each tax authority's official guidance.

Common notice types

Every authority names its letters differently, but most fall into one of these groups. Each state page sorts its notices the same way.

  • Failure to file

    The authority has no return on record for a period it expects one, often because an account is open but filings stopped.

  • Balance due

    A bill for tax, penalty, or interest the authority says is unpaid.

  • Penalty & interest

    Charges added for filing or paying late, or for underreporting.

  • Assessment

    A proposed or final determination of tax owed, sometimes estimated when returns were never filed.

  • Audit

    A request for records or notice that the authority is examining your returns.

  • Nexus inquiry

    A questionnaire or letter asking about your activity in the jurisdiction to decide whether you must register.

  • Registration

    Changes to your permit or account: required registration, filing-frequency changes, revocation, or closure.

  • Collections

    Enforcement on unpaid balances, such as liens, levies, warrants, or referral to a collection agency.

Before you pay a penalty, ask for relief

Most tax authorities have a way to ask for penalties to be waived. Each state page shows the official process, the form, and what has to be filed or paid first.

The Notice Hub is general information, not tax or legal advice. Each entry links to the official source it was checked against. Always follow the instructions and deadlines printed on your notice.
