Frequently asked questions
Straightforward answers about the product, 2026 rates and how we handle data. If you cannot find what you need, write to hello@acrogenesis.com.
Is this tax advice?
This tool automates calculations and files based on current Mexican law and the data you provide. It does not constitute tax or legal advice ("no constituye asesoría fiscal"); have your accountant review results before filing, paying or stamping.
Do I need Stripe Connect?
No. You can connect Stripe or upload a CSV (incl. Mercado Pago). Stripe Connect automates payment sync; the CSV covers other processors.
Who stamps the CFDIs?
You do, through your own Facturapi account. We generate the request; you pay stamps directly to Facturapi. Your CSD does not pass through us.
Is there a trial without a card?
Yes. You can create an account and use the product for 14 days without entering a card. After that, Stripe bills monthly until you cancel from the billing portal.
Legal-entity ISR: 2.5% or 4%?
We apply 2.5% per LIF 2026 art. 25 sec. VI (as reported by RSM and Deloitte). INDETEC bulletin BT-75 cites 4%, which is the initiative text. Confirm with your tax advisor before remitting.
Which rates does the product apply?
The 2026 rates: ISR of 2.1%, 4% or 2.5% depending on category and person type; 20% if there is no RFC. VAT withheld at 50% in the general case, 100% with no RFC, and 100% if the payout account is abroad (when the option is on). Rates and their legal basis are shown in the app and are versioned; they do not replace your accountant’s judgment.
Is 100% VAT withholding on a foreign payout account mandatory?
We apply it when the organization setting is on (the default), based on LIVA art. 18-J and LIF 2026 art. 25 sec. IX c). The rule has been described as contested (fiscalia.com; we have not verified whether that note targets the 2024 or the 2026 text). You may turn it off on your advisor’s criteria; if you do, the system records a warning.
What is art. 30-B access?
A read-only area so SAT can consult the information required by RMF rule 2.9.21, with an access log, CSV/XLSX export, a user manual and a draft escrito libre (ficha 168/CFF). We do not give SAT edit rights.
Can I see an example before signing up?
Yes. The public demo shows a month close with fictional sellers and transactions. The figures are computed by the same 2026 rules engine the application uses.
How is my data handled?
Encrypted keys (AES-256-GCM) that you can delete; transactions kept for five years; we do not sell data. Details are in the privacy notice.
Do you have customer case studies or testimonials?
No. This is a new product and we do not invent references. You can try it for 14 days or write to us for a walkthrough with sample data.
Is there a free calculator?
Yes, at calculadora.retenciones.app, with no sign-up. It is an informative estimate; it does not replace a close in the application or your accountant’s judgment.
