What the Blue Wave Means for US Expats
Democratic victories in the House and Senate have set up divided government for President Trump’s final two years in office. For Americans abroad, the practical consequence of this “lame duck” presidency is that major tax legislation (like the recent OBBBA) will become harder to enact. The new congressional majorities take office on January 3, 2027.
That suggests greater continuity in the tax rules, at least through 2028. For expatriates, this offers breathing room to plan around existing benefits but also means that longstanding frustrations with the U.S. tax system may persist. Our expectation is relative stability, rather than an assurance that every rule will remain unchanged.
Major tax legislation will face greater obstacles
Tax legislation generally requires agreement between both chambers of Congress and the president. Democrats will be able to block Republican proposals, while President Trump can veto legislation seeking to reverse his tax policies. Overriding a veto requires a two-thirds vote in each chamber. Even budget reconciliation cannot bypass the president’s veto.
Bipartisan agreements remain possible, particularly when tax provisions become part of broader budget negotiations. The outgoing Congress also retains its legislative powers until January. Nevertheless, sweeping partisan tax changes should be more difficult during the next two years.
This matters for proposals to replace citizenship-based taxation with residence-based taxation. Such reform would require legislation and agreement on difficult questions about eligibility, revenue and safeguards. Divided government adds negotiating hurdles, although it does not rule out bipartisan progress. Americans abroad should continue planning under existing law, which generally taxes citizens on worldwide income regardless of where they live.
For example, moving to the United Kingdom or Australia does not by itself end a citizen’s U.S. tax obligations. Foreign pensions, local investment funds and overseas businesses can continue to create U.S. tax and reporting issues. Those obligations should not be deferred in anticipation of reform.
The estate and gift exemption offers a planning opportunity
The 2025 tax law established a $15 million federal estate and gift tax basic exclusion per person for 2026, with inflation adjustments beginning in 2027. This is a combined lifetime gift and estate exemption: taxable gifts using the exemption reduce the amount remaining at death. The higher exemption has no scheduled sunset.
Democratic control of Congress does not itself reduce that exemption. A reduction would require new legislation, making the existing framework relatively secure politically over the next two years. “Permanent” in tax legislation means no scheduled expiration; Congress can still change the law.
For U.S. citizens living overseas, whose worldwide assets generally fall within the U.S. estate tax system, this supports deliberate planning for family gifts and succession. It may also allow suitable gifts before expatriation, after reviewing the separate exit-tax rules.
The cross-border consequences still matter. A transfer sheltered from U.S. gift tax may trigger foreign capital gains tax or transfer duties. Gifts generally carry over the donor’s U.S. tax basis, and transfers to a spouse who is not a U.S. citizen do not generally receive the unlimited gift tax marital deduction. The exemption therefore creates flexibility, not a universal recommendation to give assets away.
Existing income tax relief remains relevant
The 2025 legislation also made the current individual income tax rate structure permanent. Together with political gridlock, that reduces pressure to accelerate income solely because of an anticipated expiration of those rates.
For qualifying Americans abroad, the foreign earned income exclusion is $132,900 for 2026 and is indexed annually. Foreign tax credits remain another central tool for reducing double taxation. Eligibility and coordination matter: the exclusion does not cover investment income or pension distributions, and foreign taxes attributable to excluded income cannot also generate a credit.
A quieter legislative period is a useful time to review retirement withdrawals and investment sales against both countries’ rules.
Renunciation may attract interest but requires careful preparation
Americans who have been waiting for fundamental expat tax reform may reconsider that wait if legislative progress stalls. This could generate more interest in renunciation, although an increase is a possibility rather than an established consequence of the election.
The $15 million estate and gift exemption should not be confused with the exit-tax thresholds. Subject to limited exceptions, an individual can become a “covered expatriate” through net worth of $2 million or more, a five-year average annual net income tax liability above the indexed threshold, or failure to certify five years of federal tax compliance on Form 8854. The $2 million threshold is not indexed for inflation.
Covered expatriates can face tax on unrealized gains, with separate rules for pensions and certain other assets. Advance planning should therefore include asset valuations, compliance history and the treatment of retirement accounts. Renunciation does not erase existing federal tax liabilities.
Immigration consequences also deserve attention. Immigration lawyers have reported ESTA (travel to the United States under the Visa Waiver Program) denials and revocations affecting former U.S. citizens. Withers has reported that CBP’s Office of Field Operations confirmed that certain people with current or former U.S. citizenship connections may be unable to use ESTA.
These reports should not be treated as establishing that every former citizen is barred from visiting. An ESTA refusal may instead require a visitor visa application. Anyone considering renunciation should obtain immigration advice about future travel before making an irreversible decision.
Administrative changes can still affect US expats
Congressional gridlock does not freeze tax administration. Treasury and the IRS can continue issuing guidance within their statutory authority, and court decisions can change how existing rules operate. Funding disputes may also affect taxpayer services and processing times.
Changes already enacted also continue on their existing timetable. Business owners should check effective dates and annual elections rather than assume that a quieter Congress means their next return will look like the last one. The administration cannot simply rewrite statutory tax rates or exemptions by executive order.
Reporting obligations remain essential even when exclusions and credits eliminate income tax. FBARs and applicable filings for foreign assets, companies, trusts and investments should remain part of the thorough annual compliance review.
For 2027 and 2028, we recommend using the greater predictability to review estate plans, model major transactions in both countries and address outstanding filings. Anyone contemplating expatriation should coordinate tax and immigration advice well before scheduling a renunciation appointment.
