What TC 670 means

On your account transcript it reads: 670  Payment Normal / good news

TC 670 records a payment made after the return — toward a bill, an installment-agreement payment, or another later payment. Each payment appears as its own line with its date.

Also written as: IRS code 670, code 670 on transcript, 670 IRS code, transaction code 670.

What usually happens next

Payments reduce the balance and slow the growth of penalties and interest. When the balance reaches zero, collection notices stop. A later TC 671 or 672 reversal means the payment bounced or was reversed.

Frequently asked questions

How long does a payment take to show as TC 670?

Electronic payments usually post within a few weeks; mailed checks can take longer.

What if my payment posted to the wrong year?

Contact the IRS with proof of payment and ask for it to be moved; a CP60 notifies you when a payment is removed from a year.

Where do I see TC 670?

On your IRS account transcript for the tax year — in your IRS Online Account under tax records, or by mail using Form 4506-T. The transactions section lists each code with its description, date and amount. Return transcripts do not show transaction codes.

Is "IRS code 670" the same as TC 670?

Yes. IRS code 670, code 670 on transcript, transaction code 670 and TC 670 all refer to the same three-digit transaction code the IRS posts to your account.
