Our fees for the preparation of a Luxembourg tax return depend on the complexity based of an individuals’ specific situation and whether specific elections or reporting is required.
Effective from : 1 January 2025
Standard fees
Our standard fees for the preparation of a Luxembourg tax return are EUR 400 - 600. This covers the majority of “standard” situations (e.g. single/married/PACS, employment income, mortgage interest, typical deductions).
In some cases, additional fees are required where situations are non-standard and therefore out of scope of the standard fee. For transparency we detail the typical level of additional fees below. Where work is charged based on a time-spent basis the hourly rate applied is EUR 125 per hour.
All fees are quoted exclusive of VAT.
Tax return filing elections
Transfer-year analysis : In the year of transfer to/from Luxembourg there are different filing positions and elections to consider to determine the optimal tax position. In some cases, reporting full-year income (including income arising pre/post Luxembourg tax residence) may be required. In other cases, the optimal position will only require taxpayers to report income for the period of Luxembourg tax residence. The optimal position varies from case to case depending on individual factors & incomes. We charge EUR 125 - 250 to cover the additional calculations required in these situations.
Non-resident elections : Non-resident taxpayers have the option to be taxed as if they are Luxembourg tax residents. Whilst this can lead to some elements of double taxation it can enable higher deductions so additional analysis is required to determine the optimal filing position. The optimal position varies from case to case depending on individual factors. The tax return will be prepared based on the filing status shown on the Tax Card. Should an alternative analysis be required or requested, we charge EUR 125 - 250 to cover the additional calculations required to undertake a full analysis.
Individual/Joint elections : For married resident couples, the default filing position is a joint declaration. For registered partners (both Luxembourg tax resident) the default filing position is a single declaration. It is possible to make an election for an alternative individual/joint declaration as long as certain conditions are met. The tax return will be prepared based on the default filing status. Should an alternative analysis be required or requested, we charge EUR 125 - 250 to cover the additional calculations required to determine the optimal filing position.
Specific tax reporting
Self-employed / Commercial income : Our tax return fees quoted are based on provision of summary accounting documents (e.g. P&L, balance sheet etc.) prepared under Luxembourg Accounting guidelines. If you do not have complete accounting records then these can be prepared by our accounting team (please contact us for a separate quote). Where we are required to analyse individual invoices and/or expenses, this will be charged based on our standard fees for Accounting Services or on a time-spent basis.
Rental income : Reporting of rental income is charge on a per property basis at EUR 75 per property. This assumes that our rental tracker is accurately completed for each property. If we are required to analyse all invoices/expenses then additional fees will be charged on a time-spent basis.
Purchase of Real Estate : Specific additional reporting is required on the purchase of a property. This includes some one-time deductible expenses, lump-sum life insurance & allocation of expenses between periods of non-occupation and occupation. We charge EUR 125 for this specific reporting.
Sale of Real Estate : Sale of a Luxembourg property requires specific reporting. We charge EUR 75 for the preparation of Form 700F (where the property has been your main residence throughout ownership). For any other real estate sales we charge EUR 250 which includes the calculation of the taxable gain on the sale.
Jointly Owned Real Estate : Where Luxembourg Real Estate is held by multiple parties (e.g. siblings or non-resident spouses) then an additional co-ownership return is required to be prepared. This reports the overall income from the property and allocates this to each part-owner based on their percentage ownership. The joint property declaration (Forms 200 & 210) is charged at EUR 400 (incl. 1 x rental property). Additional properties are charged at EUR 75 per property. Where we prepare the joint-property return & each co-owners income tax returns, a discount is applied : please contact us for details.
Capital gains / Cryptocurrency / Digital Assets : The standard tax return fee is based on the provision of summary data for the calendar year showing any income (e.g. airdrops, staking etc.) plus details of any gains/losses subject to Luxembourg taxation. Each sale/trade (incl. intra-crypto) must be matched to the corresponding purchase and, where applicable, exchanged to FIAT at the date of the trade. Where additional analysis is required to determine the Luxembourg taxable amounts, this will be charged on a time-spent basis.
Tax exemption for foreign taxable salary : The Luxembourg payroll is required to calculate an exemption for income not subject to Luxembourg tax. This is common for non-residents who do not perform all working days in Luxembourg. Where the payroll exemption was not processed or does not align with the tax reporting additional disclosures and calculations are required. This will be charged on a time-spent basis.
Specific Reporting for Certain Interest Income : In certain cases, a separate filing can be made to report interest income received from EU banks/financial institutions. This filing enables the taxpayer to request a fixed 20% tax on the interest income received. Whether this filing is optimal depends on the taxpayers individual situation as joint filings for married couples are not possible. We charge EUR 250 - 500 for this reporting.
Optional tax return services
Non-resident mandate : For non-resident taxpayers a mandate can be put in place with the Luxembourg tax office. The tax office should then send any tax assessments/other correspondence to us at our offices. This option is strongly recommended to avoid potential issues with late/undelivered mail due to the fact that any letter sent by the Luxembourg tax office to a foreign address is deemed to be received within a set number of days. We charge EUR 100 per tax year for this service.
Tax return mailing/mandate agreement : This mandate enables is to sign/submit the Luxembourg tax return on your behalf. This mandate includes a request that the tax office sends copies of the tax assessments directly to us at our offices. We charge EUR 100 per tax year for this service.
Tax split calculation : In case you are filing jointly but would like to know how much of the final taxes are applicable to each spouse, we can prepare an estimate showing the taxes due/arising to each spouse, we charge EUR 125 for this calculation.
Other services
Tax card request/modification : Preparation of a request to change the tax card (e.g. Tax Class 1 or Tax Class 2) or change in withholding tax percentage (e.g. married non-resident taxpayers who have elected for joint taxation or resident spouses electing for allocation of income etc.). We charge EUR 125 - 250 per request.
Reduction/cancellation of tax advances : Preparation of a request to the tax office to reduce or cancel the tax advances. The time spent varies depending whether we need to include calculations to request reduced advances. We charge EUR 125 - 250 for this request.
Review of tax assessment : Where we have prepared your tax return the review of the final tax assessment is included in the tax return fee above. Where we have not prepared your return we can review the assessment alongside the tax return submitted for accuracy. We charge on a time-spent basis.

This is typically submitted alongside the tax declaration and, once the Luxembourg Tax Office confirm your residence position, they will sign, stamp and return the Tax Certificate to you. We charge EUR 75, per certificate, to prepare the request.
