🎄 Year-End U.S. Tax Checklist

Year-end is a time to take stock and plan ahead. It is also a good moment to check whether everything has been properly addressed from a tax perspective and to take advantage of opportunities that are still available before the new year begins.

✅ Estimated tax payment for Q4 2025

Payment deadline — January 15, 2026

If you had income in 2025 that was not subject to withholding at source, the estimated tax system requires tax to be paid evenly throughout the year. Underpayments may result in an estimated tax penalty.

➡️ The Q4 payment is the last opportunity to partially reduce this risk.

👨‍🌾 Time for tax-loss harvesting

If your investment portfolio includes loss-making securities that you do not plan to hold going forward, year-end is an ideal time to realize those losses.

How it works:

• losses offset capital gains from other transactions during the year;

• if losses exceed gains, up to $1,500 / $3,000 (Single / MFJ) may be offset against other income on the tax return;

• any unused losses may be carried forward to future years without limitation.

➡️ It is important to consider the wash sale rules: repurchasing the same asset within 30 days may disallow the tax benefit of the loss.

🎅 Non-standard tax events in 2025

If you had any atypical tax events during the year, it is best to organize them in advance before the tax season begins.

In particular:

• new sources of income;

• formation of companies or changes in ownership interests;

• transactions involving crypto assets;

• receipt of equity subject to vesting;

• opening or closing foreign bank accounts, etc.

➡️ Well-prepared documentation in advance is the best gift to yourself — and to your advisors — for the New Year 🎁
