Running a business is not a one-way street. Sometimes you need a break — because of your health, your family, your studies, or simply because the work dried up. Sometimes you decide you do not need the trade licence any more and want to end it for good. Both are entirely normal, and Czech law expects both. The trouble starts when you skip one of the steps. The result is advances you keep paying for nothing, fines for failing to notify an authority, or an argument with the tax office. Here is the whole sequence, so that nothing gets left out.
Interruption versus cancellation
Before the practical steps, it helps to separate two very different acts:
- Interrupting a živnost (trade licence) — you suspend your business activity temporarily. The licence itself survives; you simply stop using it. You can interrupt for a fixed period (six months, say) or indefinitely, and you can start again at any time with a single notification.
- Cancelling a živnost — you end the business permanently. The licence ceases to exist. If you ever want to trade again, you have to apply for a new one.
In practice: if you are not certain you will stay out of business for good, interruption is almost always the better choice. Resuming an interrupted trade is one notification, while a new application means a new procedure, new fees and a new IČO (business ID) if you gave up the old one.
Interrupting a trade licence: the full procedure
Step 1: Notify the trade licensing office
An interruption has to be reported to the trade licensing office (živnostenský úřad). You use the single registration form (JRF) — the "change sheet" section. You can file it:
- In person at any trade licensing office (they all act as a central registration point).
- Electronically through your datová schránka (data box — the mandatory state electronic mailbox).
- By post, as a form with a certified signature.
In the notification you state:
- The date from which the activity is interrupted.
- Optionally, the date on which it resumes — this is not compulsory, you may interrupt indefinitely.
Important: an interruption cannot be backdated. It takes effect no earlier than the day the notification is delivered to the trade licensing office, or on a later date you state in it (Section 31(11) of the Trade Licensing Act).
Step 2: Notify the social security office within 8 days
Within 8 calendar days of the interruption date you must inform the district social security administration (OSSZ). If you reported the interruption on the JRF at the trade licensing office, the information should be passed on automatically — but it is worth checking that the OSSZ actually received it.
Once the trade is interrupted:
- You stop paying social security advances from the month following the one in which you interrupted.
- Example: you interrupt on 15 March, so from April you pay nothing.
- For March itself — the month in which you interrupted — you still pay the advance.
Step 3: Notify your health insurance company within 8 days
The same deadline applies to your health insurance company. Here the situation is more delicate:
- Health insurance always has to be paid by someone. If you interrupt the trade and have no job and no other ground for the state to pay on your behalf (student, pensioner, parent on maternity or parental leave, jobseeker registered at the labour office), you become a person without taxable income and have to pay the premium yourself.
- The minimum monthly premium for a person without taxable income is 13.5 % of the minimum wage. For 2026, with the minimum wage at CZK 22,400, that is CZK 3,024 a month.
- If you register at the labour office as a jobseeker, the state pays your health insurance instead.
Tip: registering at the labour office after interrupting a trade is often worth it — not only for the health insurance, but also for possible unemployment benefit, if as an OSVČ (self-employed person) you took part in pension insurance for at least 12 months in the last two years.
Step 4: Notify the tax office within 15 days
You must report the interruption to the tax office within 15 days of the date it takes effect. Use the form for notifying a change of registration data. You can send it through your data box or hand it in yourself.
Step 5: VAT — a special case for registered payers
If you are a registered VAT payer, interrupting the trade does not cancel your VAT registration. You have two options:
- Apply to cancel the VAT registration — if you meet the conditions, above all that you will not be making any taxable supplies. The application goes to the tax office.
- Stay registered — in which case you keep filing VAT returns, even when they are nil. A VAT control report (kontrolní hlášení) is not filed for a period with no transactions; but as soon as you report any, a late control report carries an automatic fine of CZK 1,000 without any prior warning.
Recommendation: if you are interrupting for more than three months and expect no income at all, apply to cancel the VAT registration. It saves you a run of nil VAT returns.
Cancelling a trade licence: the full procedure
Cancellation follows a similar path, but it is final and has a few extra steps.
Step 1: Notify the trade licensing office
You file a notification that you have ceased to operate the trade (JRF — change sheet). The licence expires on the date stated in the notification, but no earlier than the day the notification is delivered.
Step 2: Notify the social security office and health insurer
The same 8-day deadlines as for an interruption. The health insurance rules are identical — someone has to keep paying the premium.
Step 3: Deregister with the tax office
Besides the change notification within 15 days, ending the trade means you also have to:
- File the tax return by the ordinary deadline for the whole calendar year — ending the trade does not shorten the tax period. In it you report only the income and expenses for the months you were in business.
- If you are a VAT payer, apply to cancel the registration and file the final VAT return.
Step 4: The annual statements for social security and health insurance
After ending the activity you have to submit the přehled — the annual statement of income and expenses — to both the social security office and your health insurer, covering the period you were in business. The deadline is one month after the deadline for the income tax return. In the statement you report only the months in which you actually traded.
Step 5: Keep your records
Once the trade is cancelled, do not forget the mandatory retention periods:
- Tax documents — at least 10 years from the end of the tax period in which the supply took place (Section 35 of the VAT Act).
- Accounting records — 5 years under the Accounting Act, 10 years for some categories.
- Payroll sheets and payroll records — 45 years for pension insurance purposes (Section 35a(4) of Act No. 582/1991 Coll.; this applies only to employers).
- Contracts — for as long as claims can arise from them, generally 3 to 10 years.
Resuming an interrupted trade
If you interrupted the trade and want it back, the procedure is short:
- Trade licensing office — file a notification that you are resuming the trade (JRF — change sheet).
- Social security office — report the resumption and start paying advances again, from the month in which you resume.
- Health insurance company — report the resumption and adjust your premium payments.
- Tax office — report the resumption within 15 days.
- VAT — if you want to be a registered payer again and you cancelled the registration, you have to apply anew.
You do not register again at the trade licensing office when you resume — your IČO and the licence itself stay the same.
Coming back to business after a break usually means setting up not only your invoicing and client communication again, but also your business address and the way you handle post. If you would rather not use your home address, a virtual registered office from MojeSidlo.cz can be a practical option, with its ListoBOX service for self-service collection of letters throughout the day and an app that shows you your scanned mail.
Checklist: interruption versus cancellation
All the steps in one place:
- Trade licensing office — notification: yes for both
- Social security office — notification within 8 days: yes for both
- Health insurance company — notification within 8 days: yes for both
- Tax office — notification within 15 days: yes for both
- VAT deregistration — recommended when interrupting, required when cancelling
- Tax return — for both, filed by the ordinary deadline for the whole year (when cancelling, with income and expenses only for the months you traded)
- Annual statements for social security and health insurance — yes for both, covering the months you traded
- Keeping records — yes for both, 3 to 10 years depending on the document
The mistakes people make
- Not telling the social security office and health insurer — they know nothing about the interruption and keep prescribing advances. You then spend months sorting out arrears and penalties.
- Forgetting about VAT — you stay a registered payer, stop filing returns and control reports, and the automatic fines pile up: CZK 1,000 for each control report filed late without a notice, CZK 10,000 when you file only after the tax office's notice.
- Leaving health insurance unresolved — you register neither as a person without taxable income nor at the labour office, and the premium debt grows quietly in the background.
- Shredding too early — you throw the paperwork out and then have nothing to prove your expenses with when an inspection arrives.
Before you stop, secure your data
Interrupting or cancelling a trade does not mean you stop needing your business records. Quite the opposite: the tax office can open an inspection covering several years back. So before you file the notification, download and archive everything.
If you use Taxorio, you can download the income and expense book for a year as a ZIP with two CSV files — income and expenses, with the category on every expense row — plus the PDF of each invoice you issued, and a full export of your account data from Settings. You will need all of it for a possible inspection, for the final tax return and for the annual statements to the social security office and your health insurer. Store it somewhere safe, ideally in more than one place, for at least 10 years.
