2025 Tax Season: Why Early Preparation Matters When Living Abroad

Major tax-law changes under the One, Big, Beautiful Bill are expected to affect upcoming filing seasons. While some provisions may take effect later, the 2025 tax year is when preparation matters most. Getting organized now ensures you enter the 2025 filing season informed, compliant, and positioned to avoid surprises.

Why Early 2025 Prep Matters

With changes unfolding and enforcement continuing to tighten, early preparation helps expats:

  • Stay ahead of evolving deductions and modified credits that apply to 2025 returns

  • Avoid delays caused by missing foreign documents or outdated personal information

  • Prepare for ongoing reporting obligations related to foreign accounts, digital assets, and international income

  • Ensure accuracy and efficiency once the 2025 tax filing window opens

What You Should Do Now

Organize your tax documents

Begin gathering documents tied to your 2025 income and assets, including:

  • W-2s and 1099s

  • Foreign wage statements and employer summaries

  • Bank and investment account records

  • Rental and business income reports

  • Digital-asset activity

  • Documentation for deductions and credits you expect to claim

Early organization reduces last-minute stress and minimizes filing risks.

Review or set up your online IRS account

An IRS online account allows you to:

  • View transcripts and past returns

  • Access IRS notices and balances

  • Confirm identity details

  • Securely authorize your tax professional when needed

This is especially helpful for expats who may face mail delays or time-zone challenges.

Prepare for direct deposit

Paper refund checks are being phased out.

If you’re an expat who still relies on mailed refunds, now is the time to secure:

  • A valid U.S. bank account

  • A prepaid card or financial service with proper U.S. routing information

Electronic refunds are faster, safer, and increasingly required.

What This Means for U.S. Expats

Although the filing deadline may feel far away, 2025 tax preparation should start now—especially for Americans living abroad. Foreign income, overseas assets, and cross-border life changes make early planning far more valuable for expats than for domestic filers.

Why Mertz International Recommends Acting Now

As a firm dedicated exclusively to expat tax strategy, Mertz International encourages early preparation because:

  • Expats face more complex documentation requirements, including foreign income reporting and account disclosures

  • Electronic refunds are now the standard, making updated U.S. banking information essential

  • Early review allows us to identify planning opportunities—or risks—before the 2025 filing season begins

  • Life changes abroad, such as moving countries, starting a business, or changing employers, can significantly impact your tax position and are far easier to manage proactively

Early action leads to clearer strategy, smoother filing, and better outcomes for 2025 and beyond.
