Montenegro is incorporating the financial obligations of future EU membership into its national budget system, with new rules covering EU contributions, medium-term budgeting, financial controls and public investment.
Parliament adopted the new Budget and Fiscal Responsibility Law on August 24, 2026, establishing for the first time a domestic mechanism for Montenegro to contribute to the EU budget after accession. The legislation is linked to requirements under Chapters 32 – Financial Control and 33 – Financial and Budgetary Provisions. Montenegro’s future annual contribution will be determined through the national budget according to the EU’s own-resources system, rather than as a fixed membership fee. The Ministry of Finance will calculate, collect, report and transfer the relevant amounts, while payments to the European Commission will be channelled through the Central Bank of Montenegro.
The EU’s current own resources include customs duties, a VAT-based contribution, GNI-based payments and a levy related to non-recycled plastic packaging waste. The GNI-based contribution is currently the largest component. Montenegro is preparing for accession while the EU’s financing system may also change. The European Commission has proposed a new 2028-2034 EU budget, potentially adding resources linked to the EU Emissions Trading System, CBAM, tobacco taxation and electronic waste. The proposals remain subject to negotiations.
Financial arrangements advance under Chapter 33
On June 30, 2026, the European Commission presented a financial package outlining budgetary arrangements for Montenegro after accession. Based on the proposed 2028-2034 EU budget, the package is designed to manage the transition from pre-accession assistance to funding mechanisms available to EU member states. It was submitted to the Council and remains subject to negotiations.
The Commission has identified the need to strengthen the Directorate for Coordination and Management of EU Own Resources, improve cooperation between institutions calculating EU revenue and upgrade customs systems to provide a complete audit trail. The financial balance of membership will depend on both Montenegro’s contribution and the EU funding it can absorb. Potential areas include infrastructure, regional development, agriculture, rural development, environmental projects, transport, energy networks, digitalisation and social programmes.
The Commission’s package envisages future support becoming increasingly linked to results and implementation of agreed reforms. Montenegro’s ability to use those funds will depend on project preparation, procurement, property resolution, staffing and national co-financing.
Stronger controls and three-year budgeting
The new law establishes an AFCOS system for coordinating institutions responsible for preventing and reporting irregularities involving European funds. An AFCOS office within the Ministry of Finance will be the principal contact point with OLAF, while institutions managing EU funds will report irregularities through an electronic system covering potential fraud, corruption and other illegal activity.
The legislation also introduces a mandatory Medium-Term Budgetary Framework covering three years. It will include expenditure ceilings, fiscal risks and contingent liabilities, including potential costs related to natural disasters and climate change. Performance indicators will increasingly be used for public programmes, while the Fiscal Council will review the framework and systematic spending reviews will identify opportunities to rationalise expenditure.
Public investment and foreign donations
The Public Investment Register and Public Investment Council are being placed on a statutory basis. Capital projects will be monitored electronically, with quarterly reporting, while the council will assess priority investments and public-private partnership projects before recommending them for the capital budget. The framework covers areas including transport, electricity networks, renewable energy, water treatment, waste management and railways, where Montenegro could seek increased European and international financing.
The government is also introducing an electronic register of foreign donations. Public spending units will have 15 working days after concluding an agreement to report donors, beneficiaries, amounts, purposes, implementation periods and financing conditions. EU funds will be excluded because they will operate through a separate control framework. The government may also identify medium-term priority areas for foreign donations.
Montenegro’s future EU contribution will therefore form only one part of its post-accession financial relationship. The wider balance will involve European structural support, agricultural funds, infrastructure financing, direct programmes, investment mobilisation and participation in the Single Market. The new legislation requires the Ministry of Finance, customs authorities, AFCOS, ministries, municipalities, public companies and procurement institutions to establish the systems needed to manage EU own resources, control spending, prepare projects and monitor investment as Montenegro moves closer to membership.
