Voluntary Disclosure and Capital Amnesties

Over the past fifteen years, banking secrecy has ceased to be a reliable shield: an account in Zurich or Singapore is now visible to the tax authority of the country of residence almost as clearly as a deposit in a local bank. Against this backdrop, the owner of "historical" foreign assets retains the opportunity to close the past on their own terms—to come to the state themselves, before it comes to them. Two such windows with a statutory guarantee are open right now — India's until the end of 2026 and Turkey's until 31 July 2027. Below is how such programs work, how a statutory guarantee differs from administrative leniency, and on what schedule the window closes.

Origins: From Banking Secrecy to Automatic Exchange

The starting point is usually considered to be 2009, when under pressure from the US Department of Justice, UBS bank handed over data on thousands of clients and paid a fine, and the Swiss model of "numbered accounts" showed its first serious crack. Events then unfolded rapidly: in 2010 the United States adopted FATCA, requiring banks worldwide to report on accounts held by Americans, and by 2014 the OECD formalized the same principle into a global standard—the Common Reporting Standard. The first automatic exchanges under CRS took place in 2017–2018; for 2024 jurisdictions exchanged data on 171 million accounts worth EUR 13 trillion, and 129 jurisdictions have now committed to exchange — Zambia the most recent, from 2028.

Capital amnesties emerged as the state's response to the same logic. If the mass of owners would soon have to explain their foreign accounts anyway, it is cheaper to give them a chance to declare assets in advance—with reduced penalties and without criminal prosecution—and return capital to legal circulation. Such programs were typically fueled by the proximity of automatic exchange: the wave of declarations arrives precisely before data exchange begins operating in the country.

Concept

Voluntary disclosure is a legal way to declare previously hidden assets or income, pay additional tax, and close the past with minimal consequences. The idea appeared long before automatic exchange, but it was CRS and FATCA that made it mainstream: when banks in dozens of countries themselves transmit data on accounts to the owner's tax authority, a hidden foreign asset will sooner or later surface on its own.

Two Regimes

Most programs distinguish between willful and non-willful violations. For those who deliberately hid assets, there is a procedure with protection from criminal prosecution at the cost of a substantial penalty. For those who violated without intent—for example, did not know about the obligation to report a foreign account—simplified procedures apply with reduced penalties or none at all.

US Example

The American system demonstrates both poles. The Voluntary Disclosure Practice (VDP, Form 14457) is designed for willful violations and removes the risk of criminal prosecution at the cost of a penalty; disclosure typically covers the last six years. Streamlined Filing Compliance Procedures, in effect since June 2014, are intended for non-willful violations: the foreign version (SFOP) allows catching up on returns by paying tax and interest without penalties. In 2025–2026, the IRS put forward for discussion a simplification of VDP with a more transparent penalty scale.

The monetary difference between the two tracks is substantial. Under VDP, the fraud penalty is 75% of the tax for the "heaviest" year of the six-year period—plus the tax itself and interest, but the threat of criminal prosecution is removed. Streamlined is noticeably milder: for those living outside the US (SFOP) the penalty is zero, for residents (SDOP)—5% of the highest value of undeclared foreign assets during the period. Everything depends on an honest assessment of willfulness: submitting a non-willful procedure for what is essentially a willful violation is dangerous, because if rejected, protection from criminal charges is lost.

Statutory Immunity and Penalty Relief

Disclosure programs fall into two classes, and the class determines what can be promised about the outcome of the procedure.

The first class is administrative practice: come forward and the sanction softens. The US VDP works this way. The IRS states expressly that a timely disclosure confers no automatic immunity from criminal prosecution: completeness and timeliness are weighed by Criminal Investigation in deciding whether to recommend prosecution, but the decision stays discretionary. The penalty scale here is internal to the agency, and the agency revises it on its own — as it proposed to do in 2025–2026.

The second class is a statutory guarantee. The statute bars the administration from auditing and assessing on the declared amount, or requires it to issue a document that closes the question. Turkey's temporary article 19 is drafted as a prohibition: where the conditions are met, no tax audit and no assessment are carried out on the declared amount. India's FAST-DS issues a Form 4 certificate granting immunity from further tax, penalty and prosecution under the Black Money Act 2015 within the declared amount.

The difference is practical. In the first class the declarant buys a probability; in the second, a provision that can be cited in a dispute. The second-class guarantee is tightly conditioned in return: it fails in full where the accompanying conditions are breached — transfer deadlines, ceilings, promised holding periods — and it extends to nothing beyond the declared amount. It operates only inside its own jurisdiction: the Turkish shield closes Turkish tax proceedings and leaves bank-side KYC/AML and residence-country obligations untouched.

Global Context

Dozens of countries have experienced their own waves of amnesties and voluntary disclosure programs—Italy, Indonesia, India, Argentina, Turkey, Russia, and others. The figure of EUR 135 billion routinely quoted alongside amnesties deserves accurate attribution. Per the Statement of Outcomes of the Global Forum plenary meeting (December 2025), since 2009 jurisdictions have identified nearly EUR 135 billion in additional revenues due to exchange of information and associated activities, of which EUR 48 billion by developing countries. The count covers the exchange machinery as a whole; the Global Forum publishes no separate line for disclosure programs.

Case Studies: Where Amnesty Worked

The most large-scale example is Indonesia. The 2016–2017 amnesty collected declarations for almost 4,884 trillion rupiah—about 35% of the country's GDP and the largest volume of disclosed assets in the history of such programs—and brought the budget about 147 trillion rupiah. The weak point turned out to be repatriation: owners readily agreed to declare foreign assets, but were much less willing to return them to the country, and the capital return plan was only partially fulfilled.

Argentina showed that less obvious motivation also works. The 2024 "blanqueo" launched by the Milei administration attracted about $22 billion to special accounts in the first stage and another $10 billion or so in real estate and other assets; according to World Bank estimates, the program uncovered hidden assets at a level of approximately 21% of GDP. European examples are more modest in share but broader in temporal coverage: the Italian scudo fiscale and voluntary disclosure of 2009 and 2015 returned tens of billions of euros to the tax field.

Open Windows: India and Turkey

Of the programs running now, two belong to the second class and carry hard dates.

India, FAST-DS 2026. The Foreign Assets of Small Taxpayers Disclosure Scheme was introduced by Chapter IV of the Finance Act 2026 (ss. 130–144) and has been in force since 16 August 2026; the rules are Notification No. 114/2026 of 14 August 2026. Form 1 is filed electronically only and only until 31 December 2026.

There are two routes. The first covers undisclosed foreign assets and untaxed foreign income: an aggregate ceiling of INR 1 crore (10 million), with payment of 30% tax on the value plus an equal amount, that is 60% of the asset value. The second covers assets already taxed or acquired while non-resident but omitted from Schedule FA of the return: a ceiling of INR 5 crore (50 million) and a flat fee of INR 1 lakh (100,000).

Assets are valued at fair market value as at 31 March 2026. Exceeding the ceiling removes eligibility altogether, returning the declarant to the general Black Money Act 2015 regime with a multiple of that burden, the annual Schedule FA penalty and prosecution exposure. The outcome is Form 4 — the immunity certificate itself. The particulars and the procedure are set out in the official FAQ of the Indian tax department.

Turkey, Varlık Barışı. Introduced by temporary article 19 of the Corporate Tax Law, added by Law No. 7582 (Resmi Gazete of 4 June 2026, No. 33270). The notification goes to a Turkish bank or intermediary institution by 31 July 2027; a foreign asset must be transferred to that bank or intermediary within two months of the notification, and physical import requires a customs declaration. The base rate is 5% of the declared value; for notifications filed between 1 January and 31 July 2027, half a point is added to every rate, taking the base to 5.5%. A commitment to hold the asset in specified Turkish instruments lowers the rate: one year — 4%, two — 3%, three — 2%, four — 1%, five — 0%. The list of declarable assets is closed: cash, gold, foreign currency, securities and other capital market instruments; real estate, shares in private companies and crypto-assets fall outside it. The mechanics are covered in detail in the article on the Turkish capital amnesty.

Both windows should be read against the exchange calendar, and they read differently. India took no CARF commitment at all, so its deadline is set by domestic decision and runs independently of exchange. Turkey sits in the second CARF wave, collecting data from 2027 with a first exchange in 2028 — meaning the Turkish window closes a year before crypto exchange starts operating, and crypto-assets were left out of the declarable list in any event.

Programmes by jurisdiction

The two open windows are the exception. Most of what is available is permanent machinery rather than a campaign, and it differs on four axes that decide which door to use: whether the relief is written into the statute or left to the administration, how long the disclosure period runs, what it costs, and whether it buys protection from prosecution.

The class column is the one to read first, because it decides what can be promised. Germany, Switzerland, Spain, India and Turkey write the outcome into the statute: a complete correction, or a certificate, and the administration is barred from going further. The American and British facilities buy a probability instead — the IRS and HMRC both say plainly that prosecution remains on the table — with one exception that is worth knowing about: the British Contractual Disclosure Facility is a contract, and the undertaking not to investigate criminally is the consideration for a complete disclosure. For deliberate conduct with a British exposure, that contract is the closest thing in the table to the German exemption.

The price column does not line up with the class column, which is the awkward part. The cheapest routes in the table — the American Streamlined procedures at nothing abroad or 5% at home, the Indian flat fee of INR 1 lakh on the second route — are cheap precisely because they are for people who did nothing deliberate. The moment intent is in play the arithmetic changes shape: 75% of the tax for one year under the American practice, a surcharge on top of tax and interest in Germany, the full offshore penalty scale in the United Kingdom. Choosing the cheap door for a case that belongs behind the expensive one is the single most costly error in this area, because a rejected non-wilful certification leaves the declarant worse off than never having filed.

The window column explains why so little of this is urgent-looking and why that is misleading. Nine of the twelve rows are permanently open, so the deadline is not on a calendar — it is the moment the administration obtains the information from its own source. What that means in practice is set out in the next section: the exchange file, the bank report and the nudge letter each move that moment closer, and none of them is visible to the declarant in advance.

Regulation: What Makes Disclosure "Voluntary"

The legal meaning of the word "voluntary" is extremely specific: disclosure is counted only if made before the tax authority learned of the violation from its own sources—automatic exchange data under CRS, bank reporting under FATCA, a leak, or an already initiated audit. As soon as information about the account reaches the inspector, the application ceases to be considered voluntary, and the preferential regime does not apply. This is precisely why the launch dates of CRS and FATCA in a particular country set the schedule for the entire structure.

The second pillar is documentary-confirmed source of funds. The tax authority will close the past period under a simplified scale, but the bank where the money is held conducts its own compliance in parallel and will require the same source of funds history as during regular onboarding. Therefore, disclosure is almost always linked to topics of beneficial ownership, UBO registers, and economic substance: declaring an asset is not enough—it must be explained in a way that passes both tax and banking filters. What such a file contains is covered in the piece on source of funds.

Between "the tax authority does not know yet" and "the tax authority already knows" lies an intermediate stage that the binary usually skips—the nudge letter. The administration sees a mismatch in exchange data, opens no audit, and tells the addressee about it, expecting them to amend the return themselves. HMRC sent about 81,000 such letters to crypto-asset holders in the tax year ended 5 April 2026—against 64,982 the year before and roughly 27,700 in 2023–24 (HMRC data as reported by UHY Hacker Young). The letter raises no assessment, yet voluntariness after it rests on goodwill: formally the window is still open, in practice the administration is already looking at that particular account.

Governments measure and publish the effect of such campaigns. The Global Forum cites two examples: Norway embedded a CRS-based prompt in its pre-filled returns, and the number of individuals reporting foreign accounts rose by close to 400% since 2018; India's NUDGE programme produced a 45.17% increase in taxpayers reporting foreign assets, an additional INR 292 billion (approximately EUR 2.41 billion) in reported assets and INR 1.09 billion (approximately EUR 104 million) in additional income. The scale of those numbers explains why administrations start with a mailing: it costs less than an audit and collects more.

In presumption terms, voluntary disclosure is the classic positive one. On its own it proves nothing about good faith, but it shifts the burden and changes two things. First, the characterisation: the declared position stops being concealment and becomes an error corrected before intervention—and, in programmes carrying a statutory guarantee, a closed episode the authority is barred from auditing. Second, the size of the sanction: the willful-violation penalty gives way to the programme's relief scale or a flat payment. The opportunity closes at one specific moment—when the authority obtained the information from its own source: an exchange file, a bank report, a leak, or an audit already under way. Whether the declarant knew of that moment is immaterial.

Risks and Nuances

Voluntary disclosure requires precise calculation. It is important to correctly determine the willfulness of the violation, choose the correct procedure, and prepare documentary history of the origin of assets—the same that the bank will require during onboarding. An error in choosing the regime can turn a mild amnesty into a full-fledged audit, so such steps are taken under the guidance of a tax specialist from the relevant jurisdiction.

Evolution: Crypto, CARF, and the Narrowing Window

The logic that worked with bank accounts is now extending to crypto assets. Seventy-seven jurisdictions have committed to implement the Crypto-Asset Reporting Framework, and the window closes in waves. On the Global Forum commitment list in its edition of 14 September 2026, 46 jurisdictions exchange by 2027 for 2026—this includes the EU through the DAC8 directive, along with the United Kingdom, the Cayman Islands and the Channel Islands, Japan, Korea and Brazil; 27 exchange by 2028 for 2027, including Switzerland, Hong Kong, Singapore, the UAE, Turkey and Cyprus; four stand at 2029 — Argentina, Azerbaijan, Mexico and the United States. Four jurisdictions identified as relevant took no commitment at all—El Salvador, Georgia, India and Vietnam. The OECD revises the composition of the waves as individual countries shift their timetables: after the Federal Council's decision of 26 November 2025 Switzerland moved from the first wave to the second, and SIF puts it more cautiously still—"not before 1 January 2027".

The clock therefore runs per venue: the window that has almost closed for bank accounts holds for crypto assets until the first exchange in the jurisdiction of the exchange or custodian—2027 for a European one, 2028 for a Singaporean or Emirati one, the stated 2029 for a US one. The genre itself is also changing—one-time political amnesties are increasingly giving way to permanent procedures like the American Streamlined, which are available at any time, without being tied to a declared "campaign." The overall vector is one: declaring an asset becomes more expensive and troublesome over time, and the space to "wait another year" is steadily shrinking.
