Checklist: Dissolving a Subsidiary After M&A

Checklist: Dissolving a Subsidiary After M&A in 12 Lawful Steps

After an M&A deal, many groups end up with "surplus entities": the acquired subsidiary's operations have merged into the parent, with no projects and no revenue — yet each year still costs accounting, audit and tax reporting, plus compliance risk. Dissolving the subsidiary is the clean exit, but the wrong sequence gets stuck at the tax stage for months. The 12-step checklist below stays in the post-M&A context.

1. Why dissolve instead of leaving it dormant?

A "dormant" entity must still: file tax reports (even nil), prepare financial statements, undergo audit (if applicable), maintain digital signatures and bank accounts, and carry its legal representative's liability. One forgotten return starts late-filing penalties running. After M&A, when the subsidiary serves no role, dissolution is cheapest in the long run.

2. The 12-step subsidiary dissolution checklist

Step 1 — Dissolution decision. The owner (single-member LLC) or Members' Council/General Meeting of Shareholders adopts the dissolution decision, asset liquidation plan and debt payment timeline. This is the source document of the whole process.

Step 2 — Form the liquidation team. Organize asset liquidation; list assets, receivables and payables.

Step 3 — Public notice. Notify employees and creditors of the dissolution decision; post at the head office; publish on the National Business Registration Portal.

Step 4 — Settle employees. Terminate labor contracts under Article 34 of the Labor Code 2019, pay all wages and severance/job-loss allowances (Article 47), and close social insurance books for each employee under the Law on Social Insurance 2024.

Step 5 — Pay debts. Practical priority: employee wages and benefits, then tax debts, then other debts (suppliers, banks). Remaining assets may only be distributed after all debts are cleared.

Step 6 — Tax finalization. File all tax returns up to cessation: VAT, CIT, PIT and related filings. This stage drags longest when books carry backlogs.

Step 7 — Confirmation of tax fulfillment. Request the tax authority's inspection and confirmation of tax fulfillment under the Law on Tax Administration 108/2025. Without it, the dissolution file cannot proceed.

Step 8 — Close the tax code. Complete tax code termination with the tax authority.

Step 9 — Return sub-licenses (if any). Sectoral business licenses and eligibility certificates must be revoked/terminated per sectoral rules.

Step 10 — Liquidate remaining assets. Sell/liquidate assets and collect receivables; the remainder after all debts is distributed to owners pro rata. Note tax obligations arising from asset liquidation.

Step 11 — File dissolution. File with the business registration agency: dissolution decision, meeting minutes, tax fulfillment confirmation, and the list of fully paid creditors.

Step 12 — Receive confirmation and archive. Receive the dissolution notice; archive books and documents for statutory periods (accounting, tax) for later inspection.

3. The three most common bottlenecks

1. Pre-M&A tax arrears. Buyers often discover hidden tax debts after closing — which is why pre-M&A tax due diligence is mandatory, not optional.
2. Unclosed social insurance books. Long-departed employees without book closure block the insurance agency's confirmation.
3. Unreconciled receivables/payables. Especially with intra-group transactions — reconcile and settle before dissolution.

4. Post-M&A dissolution vs bankruptcy

Confusing the two leads to wrong procedures and lost time.

5. Frequently asked questions

Q: After M&A, when should a subsidiary be dissolved rather than kept?

A: When it no longer has an independent business function after integration (duplicated apparatus, no projects, only maintenance costs such as accounting, audit and tax reporting). Keeping a dormant entity still costs annual compliance and carries risks.

Q: How long does dissolving a subsidiary take?

A: Typically 3–6 months with clean files: tax finalization and confirmation of tax fulfillment take the longest. Outstanding tax debts, disputes or tax audits extend the timeline.

Q: Can a subsidiary with tax debts be dissolved?

A: No. The enterprise must pay all tax debts and obtain the tax authority's confirmation of tax fulfillment before the business registration agency processes dissolution. This is mandatory.

Q: How are remaining assets handled after all debts are paid?

A: Distributed to owners/members/shareholders pro rata (after wages, allowances, tax debts and other debts are fully paid). Income from asset liquidation may trigger CIT obligations.

Q: Is tax finalization required when dissolving a subsidiary?

A: Yes. The enterprise must finalize taxes up to cessation, file all returns, obtain confirmation of tax fulfillment and close the tax code.

Q: How are employees of a dissolved subsidiary protected?

A: Full payment of wages, severance/job-loss allowances under the Labor Code 2019, and social insurance book closure for each employee. Wage and insurance arrears block the dissolution file.

6. When to work with a lawyer

Work with a lawyer when: post-M&A tax debts or payables need a handling plan; the dissolution file is repeatedly returned for unclear reasons; disputes with employees or creditors arise during liquidation; or an assessment is needed on whether to dissolve, merge or sell the subsidiary.
