How to Pay the SDOP 5% Penalty

How the Streamlined Domestic Offshore 5% penalty is paid, what goes in the envelope, and what to do if you cannot fund the full amount.

Published 28 October 2026 · Reviewed by a licensed professional
The streamlined domestic penalty is self-assessed and travels in the same paper envelope as the amended returns, so the payment has to be funded before the package is sealed.

You pay the SDOP 5% miscellaneous offshore penalty yourself, in the same paper envelope as your amended returns. No IRS bill comes first: you calculate the penalty, certify it on Form 14654 and enclose payment with the tax and interest. The IRS publishes no route for paying part now and the rest later.

That is the whole procedure in one paragraph. The rest of this guide is for the person who has done the hard part: they have rebuilt three years of returns, listed every foreign account, and reached a total they now have to fund. Most guides stop at "pay with your submission". This one covers what you are paying, how to pay it, and what to do if you cannot pay it all at once.

Key takeaways

What exactly are you paying?

Three amounts go into the envelope, and only the third is particular to the domestic track.

ComponentWhat it isWho calculates itSource
Additional taxThe extra tax shown on each amended Form 1040-X for the covered yearsYou or your preparerIRS SDOP page, step 4
Statutory interestInterest on each year's extra tax, running from that return's original due date to the date you payYou or your preparerIRS SDOP page, step 4
Miscellaneous offshore penalty5% of the highest aggregate year-end value of the assets in the penalty baseYou, on Form 14654IRS SDOP page, step 5

The IRS states the penalty as "equal to 5 percent of the highest aggregate balance/value of the taxpayer's foreign financial assets that are subject to the miscellaneous offshore penalty", taken across the covered tax return period and the covered FBAR period. Those are the most recent 3 years of returns and the most recent 6 years of FBARs. Which assets go into that base is a separate question, set out step by step in our guide to how the SDOP penalty base is measured.

Interest is where self-prepared packages most often go wrong. It runs from the original due date of each amended year, not from the day you file, and it compounds. A return from the oldest covered year carries noticeably more interest per dollar of tax than the most recent one. The IRS publishes its quarterly interest rates. Use the rates for each period the balance was outstanding, and do not apply today's rate to every year.

How do you physically pay the SDOP penalty?

The IRS page for US taxpayers residing in the United States is specific on three points and silent on the rest.

Specific:

  1. The documents "together with the payments described above, must be sent in paper form", and "electronic submissions will not be accepted".
  2. "Your taxpayer identification number must be included on your check."
  3. The package goes to the Austin address the IRS gives on that page. The IRS says that address "may only be used for returns filed under these procedures."

Silent: the page does not say whether the tax, interest and penalty must be one check or several, and it does not describe paying the penalty electronically.

Our practice fills that silence conservatively. We enclose payment in the envelope, as the page describes. We attach a one-page payment schedule that shows the tax and interest for each amended year and the penalty figure taken from Form 14654. Each figure on the schedule is tied to the document it comes from. The schedule is our own working document, not an IRS form. It gives the IRS processor, and anyone reviewing the file later, a single place where the total on the check reconciles to the returns.

Before anything is mailed, check four things:

Do you pay first, or wait for the IRS to send a bill?

You pay first. People who are used to ordinary penalties often get this wrong. An ordinary penalty is assessed by the IRS and billed to you. The streamlined domestic penalty is computed by the taxpayer: on Form 14654 you certify "that the miscellaneous offshore penalty amount is accurate."

The IRS frames the terms as an exchange. A taxpayer who follows the instructions "will be subject only to the Title 26 miscellaneous offshore penalty" in place of accuracy-related, information-return and FBAR penalties. Paying the penalty is how you take up that offer. It is not something the IRS chases afterwards.

What if you cannot pay the full amount?

No competing guide answers this question, and the IRS does not answer it either. Neither the SDOP page nor the SDOP frequently asked questions describes a submission made with partial payment, or an installment plan for the penalty itself. What the page does say is broad. Failing to follow its instructions "will result in returns being processed in the normal course without the benefit of the favorable terms of these procedures."

That sentence decides our approach. Paying the penalty is one of the listed instructions, so a submission that knowingly leaves it unpaid risks the very outcome the procedure exists to avoid. The general IRS payment plans are a collection tool for balances the IRS has assessed. Nothing on the streamlined pages says they can stand in for paying the penalty at submission. If borrowing time that way is truly the only option, that is a judgement for a licensed adviser on your specific facts, not a default.

In practice, a shortfall is solved before the envelope is sealed, in roughly this order:

  1. Recheck the figure. Overstated bases are common: an account reported correctly every year, real property held directly, or an account where you only had signature authority. Each of these stays out of the base. Removing a wrongly included asset is not a discount. It is getting the number right.
  2. Fund it from the foreign assets themselves. Moving money from the undisclosed account to a US account to pay the IRS is ordinary and expected. It does not change the penalty, as explained in the next section.
  3. Borrow on ordinary terms if needed. A personal loan or a draw against home equity is a private matter. It keeps the procedure's terms intact.
  4. Do not let the delay run on. Streamlined is closed to you once the IRS starts a civil examination of your returns, so a long wait to save up is not risk-free. Months spent saving are months in which a letter can arrive.

Does emptying or closing the foreign account reduce the penalty?

No, and this is the gap that most surprises people living in the US. The base is "determined by aggregating the year-end account balances and year-end asset values" for each year in the covered periods, and then taking the highest. Those year-ends have already passed. Withdrawing the money in the current year changes nothing about last December's balance.

The window does move. As each new FBAR due date passes, the oldest year drops out and a newer one comes in, so the base can rise or fall depending on when you file. Do not try to time your filing around that. The firm limit is the start of an IRS civil examination of your returns, and the procedure is closed to you after it.

A worked example: one household's envelope

Ravi is a green card holder in New Jersey. He kept a savings account and a mutual fund in India from before he moved, and he never reported either. All figures below are illustrative and in US dollars, converted at each year-end. The account values follow the IRS's FAQ method: list the base assets for each year, add their year-end values, and pick the highest year.

Year in the covered FBAR periodSavings accountMutual fundAggregate year-end value
Oldest year62,00041,000103,000
Year 270,00048,000118,000
Year 371,00055,000126,000
Year 474,00066,000140,000
Year 558,00072,000130,000
Most recent year39,00080,000119,000

The highest aggregate is year 4, at 140,000. The penalty is 5% of that: 7,000. Ravi withdrew money from the savings account to help with a house purchase in year 5. That brought the account down, but it does nothing to the penalty, because year 4's year-end had already passed.

His preparer then works out the additional tax on the three amended years: the unreported interest on the savings account and the fund income. The mutual fund is a passive foreign investment company, which needs its own calculation and, for the covered years, its own Form 8621. Interest is then added on each year's additional tax from that year's original due date. The envelope carries the amended returns, the signed Form 14654 showing 7,000, copies of the certification on each return, the payment schedule, and the checks.

If Ravi could not fund all of it, the first step would be the recheck. Suppose the fund had been reported on a timely FBAR and Form 8938 in one year, with all its income declared. It would score zero in that year. That alone could move which year sets the base. The second step would be the fund itself. Selling part of it to pay the IRS is permitted. The sale has its own tax result in the year of sale, so it should be planned, not rushed.

What if the figure turns out to be wrong?

An error can be corrected, but only one way is published. The SDOP FAQ says that where the returns are not under examination, "you may correct the error by providing corrected amended returns and/or an amended Form 14654". Its worked example of an understated penalty adds that the taxpayer must provide "payment for the increase". The SDOP page itself also warns that "you may receive a balance due notice or a refund if the tax or interest is not calculated correctly". Note that it mentions tax and interest, not the penalty.

Holders of certain Canadian retirement plans have one more route. Form 14708 asks for reconsideration of the penalty where those plans were included. The IRS ties that form to the Canadian plans its FAQ describes, not to errors in general.

Where we fit

We prepare the whole domestic streamlined package: the three amended returns, the six FBARs, the penalty inventory, Form 14654 and the payment schedule that ties them together. The work is reviewed by our IRS Enrolled Agent, who is also ACCA-qualified, before anything goes to you. You sign the certification and mail the package yourself. We never submit on a client's behalf. If the total looks unaffordable, we would rather recheck the base with you before you file than after. Book a consultation to start.

Frequently asked questions

How do I pay the streamlined domestic offshore penalty?+
You enclose payment for it in the paper package you mail to the IRS streamlined unit in Austin, Texas, together with the amended returns, the signed Form 14654, and payment of the additional tax and interest. Your taxpayer identification number must be on the check. Electronic submissions of the package are not accepted.
Do I pay the 5% SDOP penalty with my submission or wait for a bill?+
You pay it with your submission. The streamlined domestic penalty is self-assessed: you calculate it, certify on Form 14654 that the amount is accurate, and enclose payment. The IRS does not send a bill first, unlike an ordinary penalty that it assesses and then collects.
What if I can't afford the SDOP penalty?+
The IRS publishes no route for submitting under the Streamlined Domestic Offshore Procedures with partial payment, and it warns that not following the instructions means returns are processed without the procedure's favourable terms. Recheck the penalty base first, fund the shortfall from the foreign assets or ordinary borrowing, and take licensed advice before relying on a payment plan.
Does closing or emptying my foreign account reduce the SDOP penalty?+
No. The streamlined domestic penalty is 5% of the highest aggregate year-end value of the assets in the penalty base across years that have already closed. Withdrawing or moving the money now does not change those past year-end balances, so it does not reduce the penalty.
What happens if I calculate the SDOP penalty wrong?+
If your returns are not under examination, the IRS FAQ lets you correct the error with corrected amended returns and/or an amended Form 14654, and where the penalty was understated you include payment for the increase. Errors in the tax or interest may instead produce a balance due notice or a refund.
