Deadline for New Non-Habitual Resident (NHR) Applications
If you’re looking to take advantage of the updated Non-Habitual Resident (NHR 2.0/IFICI) tax regime, please note that the deadline to apply for the 2024 tax year was March 15, 2025. Missing this cutoff means waiting another year to access these tax benefits.

Key Personal Tax Dates to Keep in Mind
In addition to the NHR application, there are several other tax-related deadlines to be aware of. These may shift slightly from year to year, so early preparation is always recommended. Important items include:

• IRS 3 (Personal Income Tax) Filing: The Portuguese tax year follows the calendar year, and your IRS3 return (Imposto sobre o Rendimento das Pessoas Singulares) must be filed by June 30 of the following year. This report includes all global income. Ensure you gather necessary documents like income proofs, deductible expense receipts, and bank statements well in advance.
• Claiming Tax Deductions: Expenses on health, rent, education, gym fees, and vehicle upkeep can qualify for deductions. To make use of these, you must validate your receipts on the e-Fatura portal by February 25 each year.
• IMI – Municipal Property Tax: Payments for this tax are typically spread throughout the year depending on the amount owed:
  • €100 or less: Full payment due by May 31.
  • Between €100 and €500: Two installments — May 31 and November 30.
  • Over €500: Three installments — May 31, August 31, and November 30.
• Social Security for the Self-Employed: If you’re self-employed or earn qualifying income, you may be required to make social security contributions. After your first exemption year, you’ll need to submit a report every quarter and pay monthly.

Why is it important to use the same tax preparer for all your returns?

When it comes to taxes, consistency and accuracy are key. Using the same preparer for all your tax returns in Portugal and the US (IRS3 personal income tax, wealth tax, corporate tax, Form 1040, FinCEN 114, etc.) offers several advantages:

Consistency between Returns: Each tax return is interconnected. If you use different tax preparers, errors can occur in the information you report on each Form, generating inconsistencies that may attract the attention of any of the two Tax Agencies.

Reducing the Risk of Errors and Penalties: The Tax Agency in Portugal cross-references data between with the IRS. A tax preparer who handles all your returns will ensure there are no discrepancies, avoiding inspections or fines.

Tax Optimization and Tax Savings: A single advisor can structure your taxation efficiently and take advantage of deductions and exemptions in one tax that reduce the burden on another (for example, offsetting losses in Corporate Income Tax).

Deep Understanding of Your Personal Situation: An advisor who knows your financial history can anticipate problems and opportunities. You won’t have to review everything from scratch every year, which saves time and money.
