# Frequently asked questions

> Short answers to the questions we hear most

> [accordion] Does TaxLayer send anything to AADE?
>
> No. TaxLayer reads from myDATA; it never transmits. Your existing process for reporting to AADE is unchanged. When the Co-pilot finds an invoice you paid that the supplier never filed, it tells you the deadline to file it yourself as the recipient in AADE's portal.

> [accordion] Does TaxLayer replace my accounting system?
>
> No. It sits alongside it, checks it against myDATA, your documents and the bank, and tells you what doesn't match. Your ledger stays where it is.

> [accordion] Which files can I upload?
>
> PDF, PNG, JPG, JPEG and TIFF, up to 20 MB each, for documents and bank statements. Spreadsheets from your accounting system go to Books & ledgers (.xlsx, .xls, .csv).

> [accordion] I entered my myDATA codes but the figures are empty.
>
> Give it a minute for the first sync. If the Home page says *myDATA sync failing*, the codes are wrong or are for AADE's test environment — re-enter the production codes.

> [accordion] Why doesn't the Co-pilot show anything?
>
> It needs the Pro plan and a Reconciliation agent. Press *Create your Reconciliation agent* and walk the steps; the first run starts straight away.

> [accordion] Can my clients use it too?
>
> Yes, two ways. Give a contact portal access and they see only their own company. Or invite the client to open their own account and link it to your firm; they pay for their own plan and you see their books.

> [accordion] Is there a trial?
>
> No. Every account starts on the Free plan, which has no time limit. Upgrade when you need more than 10 documents, one client or one user.

> [accordion] A number looks wrong. What do I do?
>
> Click it. Every figure opens to the months, documents or transactions behind it. The *myDATA data as of* line shows how fresh it is. If it's still wrong, email support with the client name and the period.

> [accordion] How do I get help?
>
> Email [support@taxlayer.io](mailto:support@taxlayer.io). Include the client name, the period and, if it's about one document, its number.
