IRS FTB and CDTFA notices organized by deadline and tax period

Review the primary official source.

Tax procedure begins with the exact notice and agency. These answers explain how to classify a federal or California dispute before selecting an appeal, collection remedy, or documentation plan.

Which agency sent the tax notice?

IRS, FTB, CDTFA, EDD, and local agencies use different procedures. Identify the exact agency, notice number, tax period, amount, proposed action, response address, and deadline before choosing a remedy.

Practical next steps

  • Identify the issuing agency, tax type, period, notice number, response date, asserted balance, and present collection status.
  • Reconcile the return or assessment to source records instead of sending an unindexed document dump.
  • Preserve the notice, envelope, fax or upload receipt, certified-mail proof, call notes, and copies of every submission.

Documents to gather

  • returns and account transcripts
  • notices and proof of service
  • bank, payroll, ledger, invoice, and receipt records
  • prior protests, appeals, payments, and agreements

Should a taxpayer call or respond in writing?

A call can clarify status, but preserve a written, dated record when rights or deadlines are involved. Keep the notice, envelope, fax or upload confirmation, certified-mail proof, account transcripts, and representative authorization.

Can an IRS deadline be extended?

Some deadlines can be extended and others cannot. Never infer an extension from a phone call or pending document request. The notice and governing statute control.

How do federal and California matters interact?

An IRS adjustment can affect a California return, but the agencies do not share one appeal. Track each notice and period independently and consider reporting obligations after a federal change.

What records should be organized?

Prepare returns, notices, transcripts, source documents, bank and payroll records, entity documents, prior submissions, proof of delivery, and a period-by-period calculation of what is disputed and why.

What should be done immediately after an IRS levy notice?

Identify the exact notice, tax periods, response date, collection contact, and whether property has already been levied. Contact the IRS through the notice, preserve proof, and evaluate the remedy actually offered; the IRS CDP FAQ and levy-release guidance distinguish hearing, appeal, release, hardship, and payment options. A levy release does not erase the debt.

  • Identify the issuing agency, tax type, period, notice number, response date, asserted balance, and present collection status.

How do IRS, FTB, CDTFA, and EDD procedures differ?

They administer different taxes and use different notices, protest routes, collection powers, and review bodies. Build a separate line for each agency, account, period, assessment, deadline, payment, and pending proceeding. Do not send one agency’s form to another or assume a federal extension controls California.

What records support an audit involving personal and business activity?

Separate bank and card accounts where possible, then reconcile returns, ledgers, invoices, receipts, contracts, payroll, mileage, basis, digital-platform statements, and owner transfers. For mixed accounts or emerging transactions, document business purpose and allocation methodology rather than relabeling personal charges.

Practical next steps

  • Identify the issuing agency, tax type, period, notice number, response date, asserted balance, and present collection status.

What is the path for protesting an assessment or seeking settlement?

Follow the notice: an IRS examination, FTB NPA, CDTFA determination, and collection action use different protests and appeals. The FTB NPA protest guide and CDTFA appeals publication explain agency-specific steps. Settlement or collection alternatives require substantiation and do not replace a timely protest.

  • Identify the issuing agency, tax type, period, notice number, response date, asserted balance, and present collection status.

When is a tax attorney different from a CPA or enrolled agent?

CPAs and enrolled agents often prepare returns and represent taxpayers administratively; a tax attorney may be important for legal privilege, litigation, criminal exposure, complex entity or transaction issues, and coordinating federal and state disputes. Verify credentials, scope, forum admission, fee structure, and who will perform the work.
