Good to know.

Create an account with your email and password, or sign in with Google. Verify your email if prompted. Then add your company: you can adopt verified details from the government portal or enter them manually. Your company must already be registered for Union OSS in Cyprus. Add your billing address no later than when purchasing a quarter.

Enter the username and password you use for the Cyprus government's Tax-OSS portal. Verification retrieves your OSS registration and existing reporting quarters. If you do not have these credentials, ask your accountant or contact support@oss-cyprus.com. Your OSS Cyprus login is a separate account.

Use Amazon's VAT transaction report in CSV or TXT format. Monthly and quarterly reports are supported. Select up to 12 files at once; each may contain up to 250 MB (250 MiB) and 500,000 data rows. Files are processed in sequence and checked individually. Ordinary order or payout reports without the required tax information are not sufficient.

Not necessarily. Each file shows its detected period and how it is used. Earlier reports can help match refunds to the original sale; you do not need to create another quarter for that. You still need the relevant reports for the quarter you are preparing. Overlapping entries are checked, and conflicting data needs review.

You can see the available totals: net OSS sales, current-quarter VAT, included prior-quarter corrections and estimated VAT payable. Country and return-position counts and a refund overview are also included. Any country credit is shown separately. Missing months and open questions remain visible. Values may be provisional while confirmations are pending; unreliable or outdated totals are not displayed. The quarter package adds the full country and VAT breakdown, correction details, exports and transfer to the OSS portal.

Compare the same scope: our current sales totals include refunds for sales in this quarter. Refunds relating to earlier sales appear separately as corrections. Your own analysis may already deduct these from its total. Exchange rates, rounding or filters can also cause differences. Open “Compare with your own analysis” for an explanation of our calculation. A difference alone does not establish a calculation error.

Current sales use the ECB rate at the end of the selected quarter, or the next published rate if unavailable. Corrections to earlier sales use the original quarter's rate. A missing required verified rate blocks the calculation until resolved.

Corrections can create a credit in one country. It does not reduce payment to other countries. For example, €100 VAT in country A and a €2 credit in country B give a €98 balance but €100 payable. A displayed credit is not a confirmed repayment.

Required adjustments to submitted Union OSS returns are included in a later return, identifying the original quarter, the Member State of consumption and the VAT adjustment. OSS Cyprus prepares them separately from current sales. The OSS window is three years from the original filing deadline. Whether later corrections are still accepted depends on national rules; contact the relevant Member State directly.

No. OSS Cyprus handles clearly matched refunds automatically. For earlier quarters, we ask once when needed whether the original sales were reported and the refunds have not yet been accounted for. Only unclear allocations or amounts already accounted for need specific review.

Open the case and check the quarter, country and amount. Add the earlier Amazon report if needed, or clarify the previous return with your accountant, for example if it was a nil return. Where offered, you can explicitly defer the affected correction for this quarter. It remains open and is excluded from the draft. The remaining figures can proceed after rechecking. Small amounts also need to be resolved.

Amounts already accounted for must not be reported again. You can identify fully or partially accounted-for cases, and partial amounts are documented. Calculation and reporting versions remain saved. Changes made outside OSS Cyprus must be reconciled before the next transfer.

OSS Cyprus calculates the figures and enters them in the Cyprus OSS portal after your confirmation, including the prior-quarter corrections included in your result. The completed return is saved as a draft. Review the figures, click Submit in the government portal and pay the OSS tax to the authority. A saved draft is not yet a filed return.

Yes. Under “My quarters”, you can explicitly create earlier quarters from Q3/2021 and upload their reports. This does not overwrite filed government returns; corrections have their own deadlines and checks. Uploading an older report only as a reference in your current quarter does not create an automatic retrospective return or another quarter package.

No. A return or price credit may reduce the taxable amount, subject to national conditions. What matters is whether a previously reported OSS sale actually needs to be adjusted. Missing tax information is not guessed.

Already filed returns are not overwritten. Existing different drafts are backed up and compared with the proposed figures. A full replacement takes place only after your explicit confirmation.

Your account shows the currently available payment method and the confirmed total. You purchase one package per company and quarter, without a subscription. Access is unlocked after verified payment receipt. You pay OSS tax separately to the authority.

If your banking app supports EPC/SEPA QR codes, scan the code shown in the payment details. Check the recipient, amount and reference, then confirm the transfer in your bank. If the app does not recognise the code, copy the bank details and reference into an ordinary transfer. Scanning alone does not make a payment or unlock the quarter.

Only when you explicitly grant access to the specific quarter for up to 48 hours. You can revoke access at any time. Your government password is never displayed.
