How to close a business without the pain: winding up a sole trader business and a limited company

Ending a business can be the most stressful phase of running it, more than setting it up. The formalities are spread across different authorities (the Central Register and Information on Business (CEIDG), the National Court Register (KRS), the Social Insurance Institution (ZUS), the tax office), deadlines are short, and any mistake can lead to penalties many years after closure. In this article we set out two routes: closing a sole trader business (JDG, the simpler one) and winding up a limited company (sp. z o.o., the more complex one), with specific deadlines and a checklist.

Sole trader: closing in 4 steps

Closing a sole trader business is simpler than winding up a company. There is no formal liquidation procedure, and it is enough to be struck off the Central Register and Information on Business (CEIDG). But before you do that, you must settle your accounts.

Step 1: deregistering employees

If you employ people, you must end their contracts in line with the Labour Code. For most it will be by giving notice (depending on length of service), and for a few by mutual agreement. At the same time:

1. Deregistration from ZUS: form ZUS ZWUA, within 7 days of the end of the contract
2. Certificate of employment: issued on the day the employment ends
3. PIT-11: for the period worked in the year the employment ends
4. Handing over documents: personnel files given to the employee or archived

If there are collective redundancies (at least 10 employees in firms of up to 100 people, or at least 10% in larger ones), the additional procedures under the Act on collective redundancies apply: consultation with the local labour office (PUP), notice to employees 30 days in advance, and a support programme.

Step 2: the liquidation stocktake

On the day the business ends, you draw up a physical count of all goods, materials and finished products left in the business. For every item on which VAT was deducted when it was bought, you must pay the VAT back in the last return.

Step 3: the application to strike off CEIDG

You file form CEIDG-1 (the “removal from the register” tab) online through biznes.gov.pl or in person at the municipal office. The required details are:

• The date the business ceased
• A statement that there are no tax liabilities (or that they have been paid)
• Notifications to ZUS/KRUS (if applicable)

The entry is struck off CEIDG immediately, with no fees and no waiting. The NIP (tax identification number) and REGON number stay “frozen” and can be recovered if you set up a business again in future.

Step 4: final settlements

After you are struck off CEIDG, the tax formalities remain:

| Return | Deadline | |------------|--------| | Last VAT return (with the stocktake) | 25th day of the month after the month of liquidation | | JPK_V7 for the last period | 25th day of the month after the month of liquidation | | Annual PIT for the year of liquidation | by 30 April of the following year | | ZUS DRA return for the last month | 20th day of the month |

Deregistration from ZUS as a contribution payer: form ZUS ZWPA within 7 days of ceasing the business.

Limited company (sp. z o.o.): the liquidation procedure

Liquidating a limited company is much more formal. It requires a resolution, the appointment of a liquidator, announcements, a period for creditors and only then removal from the KRS.

Stage 1: the dissolution resolution (month 1)

The shareholders’ meeting passes a resolution to dissolve the company.

The resolution sets out:

1. The reason for dissolution, most often “a resolution of the shareholders”
2. The appointment of a liquidator, most often the existing management board, but it can be an outside person
3. The place where documents will be kept after liquidation

Stage 2: registration and announcements (month 2)

The resolution is reported to the registry court (KRS) within 14 days. The court enters the change, and the company becomes a “limited company in liquidation” (an obligatory suffix on all documents, invoices and correspondence).

At the same time the liquidator announces the dissolution in the Court and Commercial Gazette (MSiG). This starts the 6-month period in which creditors must submit their claims.

Stage 3: the liquidation proper (months 3–8)

For at least 6 months from the announcement, the liquidator:

• Closes current operations: ends contracts, collects receivables, pays debts
• Sells the assets: liquidates assets and turns the warehouses into cash
• Draws up balance sheets: an opening and a liquidation balance sheet
• Handles reporting: VAT, CIT and ZUS as usual, plus special reports for the KRS

Stage 4: distribution of assets and striking off (months 8–12)

Once the liquidation is complete, the liquidator:

1. Draws up a liquidation balance sheet at the end of the process
2. Distributes the remaining assets among the shareholders (according to the articles of association)
3. Files an application to strike the company off the KRS
4. Hands the documents over for archiving

The court strikes the company off, and its legal existence ends for good.

Taxes on the liquidation of a company

CIT

The company’s last financial year ends on the day the liquidation ends.

Paying out assets to shareholders

We discuss the tax consequences of paying liquidation assets to shareholders individually.

VAT on liquidation

As with a sole trader, there is a liquidation stocktake of the goods left in the company, and the VAT is payable in the last return.

e-Delivery and archiving

Companies entered in the KRS must have an electronic delivery address (e-Delivery), and from 1 October 2026 so must businesses entered in CEIDG. After the business closes:

• Sole trader: the e-Delivery mailbox expires when you are struck off CEIDG
• Limited company (sp. z o.o.): the mailbox is kept by the liquidator until the company is struck off the KRS

Archiving documents

Retention periods after the business closes:

| Type of document | Period | |------------------|--------| | Accounting documents, VAT, PIT/CIT | 5 years from the end of the year of payment | | Employee records (employed from 1 January 2019) | 10 years from the end of the year in which the employment ended | | Employee records (employed earlier) | transitional periods (up to 50 years) | | The payer’s ZUS records | 5 years | | Invoices from KSeF (the national e-invoicing system) | 10 years in the Ministry of Finance system | | Financial statement files (limited company) | Permanently |

You can hand the documents over to a qualified external archive. Costs start at PLN 50 a month for a small business.

The most common mistakes when closing

Based on inspections in recent years:

1. A stocktake that is too late: doing the count after the date of removal from the register (legally impossible)
2. Not paying back VAT on the remaining assets: a frequent correction after the event, with interest
3. Forgotten final returns: VAT, JPK, annual PIT
4. Not deregistering from ZUS as a payer: this generates demands for months afterwards
5. No archiving: after an inspection, missing documents lead to estimated liabilities
6. Not closing the company bank accounts: the bank asks for a certificate from the tax office

Summary

Closing a business is a process that needs planning, several months before the end date, not only when it is due. At Profais we handle the complete closing of sole trader businesses and the liquidation of limited companies (sp. z o.o.), from planning the deadlines, through the final returns, to archiving the documents. See our full accounting service and our revenue and expense ledger (KPiR) service. If you are considering the alternatives, see the article on succession of a sole trader business or on converting into a limited company (sp. z o.o.).
