This page summarizes the legal framework CifraHQ's ITBMS withholding module is built against. It is not legal advice — consult your CPA or tax counsel for binding interpretations.
Establishes the ITBMS withholding agent regime in Panama. Designated agents withhold a portion of the ITBMS billed on supplier Invoices and remit it directly to DGI.
Modifies DE 84/2005 Article 19, fixing the withholding rate at 50% of the ITBMS billed for designated agents.
Designates the 736 entities that operate as ITBMS withholding agents for the 2026–2027 biennium. Each successor resolution covers a new biennium and may add or remove agents.
Verify your designation status: if your entity does not appear on the current resolution, you are not required to act as a withholding agent. Leave the Designated ITBMS Withholding Agent flag off in CifraHQ.
CifraHQ aggregates retentions by ITBMS rate bucket. The current rates are:
| Rate | Applies to |
|---|---|
| 7% | Standard ITBMS rate for most goods and services |
| 10% | Alcoholic beverages, tobacco Products, hotel accommodations |
| 15% | Telecommunications services |
The 50% withholding applies on top of whatever ITBMS the supplier billed. A USD 100 invoice with USD 7 ITBMS yields USD 3.50 withheld (rounded half-up to 2 decimals).
| Window | Action |
|---|---|
| 1st of month | Filing period opens for the prior month's retentions |
| 1st – 15th of month | Upload Formulario 4331 to DGI e-Tax 2.0 with the prior month's data |
| 15th of month | Deadline. Late filings incur a minimum USD 10 penalty plus interest. |
Filing follows the same monthly cadence as the supplier-side Formulario 430.
DGI provides a Certificate Authenticity Verification service in e-Tax 2.0 that lets DGI auditors confirm a retention certificate came from a designated agent. CifraHQ's per-certificate verification URL — https://verify.CifraHQ.cloud/cert/{token} — is a tenant-side complement that supplies the same data (number, agent, supplier, period, amount) without requiring DGI portal access.
Suppliers receiving a certificate should verify both:
Tenants with annual revenue over USD 11,000 must have a CPA attest to the monthly close. CifraHQ enforces this via the Require CPA Approval to Close toggle in Settings — when on, the Form 4331 cannot be Submitted until a CPA user has approved it.
The CPA's DGI code is recorded on the return for traceability.
| Violation | Penalty |
|---|---|
| Late filing | Minimum USD 10 + interest + surcharges (Fiscal Code) |
| Failure to file | Higher penalties scaled to the unfiled amount |
| Failure to issue a certificate | Penalty per missed certificate |
| Tampering with a certificate | Criminal penalties under the Fiscal Code |
Per the 5-year retention rule, retain at minimum:
CifraHQ retains all of these as long as your tenant is active. After tenant deactivation, an export is recommended before any data purge.
CifraHQ does not (today):

| Formulario 4331 | Monthly withholding agent declaration | Accounting → Form 4331 |
| Formulario 430 | Monthly supplier ITBMS return — line 52 Reports retentions received | Accounting → Form 430 |
