Quick Answer
It’s advisable to hire support when obligations or volume exceed your internal control, but the service must define responsibilities, cut-off dates, deliverables, access, and extras. Paying a monthly fee without documented scope does not guarantee control.
Decide when to hire an accountant and what the monthly service should include based on volume, obligations, risks, and deliverables.

Before Acting
Fiscal responsibility does not disappear when delegating. Maintain access to your receipts, files, bank statements, and important decisions.
What This Means in Practice
Hiring monthly accounting does not eliminate business involvement. The taxpayer continues generating sales, hiring, collecting, paying, and providing evidence. The service works when there is a clear boundary between operation, recording, review, filing, and decision-making.
Before comparing prices, document the scope. Two proposals with the same monthly fee can be very different if one includes reconciliation, payroll, and handling requests, and the other only captures and files returns.

Frequently Asked Questions
At what income level do I need an accountant?

Should the accountant have my passwords?
Define minimum access, responsible parties, and controls. The e.firma and other authentication methods require special safeguarding; avoid sharing them without process and traceability.
What should I receive each month?
