Frequently Asked Questions

To correctly calculate Capital Gains and ensure compliance with the FIFO (First-In, First-Out) rule, we must know the exact Acquisition Value (purchase price) of every asset you sold this year. If you sold a stock in 2025 that was purchased in 2020, we need the 2020 file to find its original cost. Always upload your complete account history.

Always use the Excel/CSV export, not the PDF. The PDF statement lacks the critical metadata needed to correctly distinguish special dividend types (like 'Return of Capital') from regular dividends, which can lead to misclassification.

No - upload the file exactly as your broker exported it. Opening a CSV in Excel or Numbers and saving it often corrupts the file: it changes the decimal/thousand separators ("." and ",") or the character encoding, which causes errors. This is especially common with Revolut exports.

You can still use Tax-wizard. We provide a Generic Excel Template for you to structure your data into a format our system can read. Learn more here.

Small discrepancies (a few cents) are generally due to rounding. The Tax Authority requires rounding to two decimal places per line item. Tax-wizard aligns with AT rules by rounding individual transactions before summing them, which may cause minor differences from your broker's lump-sum totals.

This typically means the file is corrupted, invalid, or is in the wrong format. Download a fresh copy of the file directly from your broker and ensure you are using the exact file type specified in our guides.

The Normal plan is limited to one or two taxpayers (suitable for individual or joint declarations). The Business plan has no limit on the number of taxpayers, making it ideal for accountants or corporate users.

The fee covers the current fiscal year (e.g., 2026). You can use the service unlimited times for that specific tax year. Renewal is manual if you wish to use it next year.

We offer refunds if our system cannot process your valid broker files due to an internal technical failure that we cannot resolve. We strive to troubleshoot all issues first before issuing a refund. Refunds usually process within ~24 hours but can take 5–10 business days to appear, depending on your bank.

No. There are no automatic subscriptions and you will not be auto-charged. A purchase is valid for one specific fiscal year, and the account resets each fiscal year. If you used it last year, a new payment is needed for the current year - renewal is manual.

A partner or affiliate discount only applies if you complete the purchase through that same partner link. Starting checkout from a different link won't carry the discount. If you completed checkout through the partner link and the discount still didn't apply, contact support.

The system asks for your NIF right after purchase. If the invoice was already issued to "consumidor final" (final consumer), send support your fiscal details - we'll issue a credit note for the original and generate a new invoice with your data.

Contact support and we'll refund the duplicate payment. It typically appears back on your card within ~5–7 business days, depending on your bank.

Tax-wizard doesn't store or use phone numbers. The payment page language and the SMS verification come from Stripe (Stripe Link), our payment processor - not from Tax-wizard - and are controlled on the Stripe side.

We process your files to generate your report and do not keep your transaction statements permanently - we don't retain them in our database to maintain your privacy and security, and they are not used for AI training, analytics or marketing. Generated reports are available to download immediately after processing. If you want to regenerate a report later, you'll need to re-upload your files.

Just ask. On request we delete your account and all associated data and confirm it by email.

For security, send us an email from the new address to confirm ownership before we switch it. If you simply registered with a typo, we can correct the spelling so you receive all communications.

For Portugal you get a simulation file (to test in the AT simulator), a submission XML (the file you actually deliver on the AT portal), and an Excel summary. The downloadable reports include a compilation of all transactions, an acquisition/realization breakdown, a compilation of received dividends, and a summary. A PDF that just mirrors the on-screen panel is not the generated report - the actual files are in the download area.

The XML is generated only when you also upload your pre-filled declaration (the XML exported from the AT / Finanças portal) alongside your broker files - the tool needs it to produce the submission XML. If you only got the Excel, the pre-filled declaration step is missing. The simulation and submission files can legitimately differ in line count; submit the submission XML, not the simulation file.

Yes, but if your mobile browser won't let you attach the XML or download the generated files, use a desktop computer browser - that resolves most upload/download issues.
