Wealth Tax Advances Adjustment & IRC/ICC Advances Adjustment Payments: Optimising Your Corporate Tax Obligations in Luxembourg

Introduction

In Luxembourg, companies are required to make advance payments toward certain taxes, including the Net Wealth Tax (NWT) and Corporate Income Taxes, namely Impôt sur le Revenu des Collectivités (IRC) and Impôt Commercial Communal (ICC).
Managing and adjusting these advances correctly is essential to avoid overpayments, penalties, and unexpected year-end liabilities.

Our Tax Advances Adjustment Service ensures that your prepayments are accurately aligned with your projected tax liabilities, keeping your business compliant while optimising cash flow.

What are Tax Advances in Luxembourg?

  • Wealth Tax Advances: Prepayments made toward your annual net wealth tax obligation, based on the value of your company’s net assets.

  • IRC Advances: Quarterly payments toward your corporate income tax.

  • ICC Advances: Quarterly payments toward the municipal business tax.

The Administration des Contributions Directes (ACD) sets these advances based on previous tax filings, but adjustments may be necessary when your business circumstances change.

Why Adjust Tax Advances?

Adjustments are often required if:

  • Your profits are significantly higher or lower than in previous years.

  • Your net asset value changes, affecting wealth tax liability.

  • Your business activity expands, contracts, or changes sector.

  • You want to optimise cash flow and avoid tying up excess funds in overpaid taxes.

Without adjustment, you risk:

  • Overpayment: tying up capital unnecessarily.

  • Underpayment: facing interest charges or penalties.

Our Adjustment Service Covers

  1. Tax Position Review: assessing current and projected liabilities for NWT, IRC, and ICC.

  2. Advance Payment Recalculation: determining the optimal advance amount based on updated forecasts.

  3. Preparation of Adjustment Requests: completing and submitting formal requests to the ACD for revision.

  4. Compliance Check: ensuring all filings meet Luxembourg tax regulations.

  5. Follow-Up with Authorities: managing correspondence and securing confirmation of adjusted schedules.
