A Panama boat business needs a RUC, electronic invoices showing 7% ITBMS, monthly ITBMS returns and a yearly income tax return due three months after the fiscal year ends. A contador público autorizado (CPA) must endorse returns above B/.11,000 of gross income. Hire a Panamanian accountant before your first booking, not after.
The yearly tax calendar
These are the recurring filings for a company with a calendar fiscal year. Your accountant will confirm them for your case.
| Obligation | When | Agency |
|---|---|---|
| ITBMS return and payment | Monthly, within the first 15 days | DGI |
| Income tax return (declaración jurada de rentas) | Three months after year-end: 31 March, with an approved extension to 30 April | DGI |
| Estimated income tax instalments | Six, nine and twelve months after year-end | DGI |
| Aviso de operación tax | Three months after year-end | DGI |
| Tasa única (B/.300 for an S.A.) | 15 January or 15 July, depending on registration date | DGI, via the resident agent |
| Employer and employee CSS contributions | Monthly; confirm the date with the CSS | CSS |
| Municipal tax | Per the municipality's schedule | Municipal treasury |

Income tax: territorial, 25% for companies
Panama taxes on a territorial basis: only income from Panamanian sources is taxed. A charter run in Panamanian waters earns Panamanian-source income. Companies pay a flat 25%, according to PwC. A minimum-tax calculation (CAIR) applies only above US$1.5 million of taxable income, which few boat businesses reach.
Under Ley 280 of 2021, as the DGI explains, a return showing gross income above B/.11,000 must be endorsed by a CPA registered with the DGI. That means your books must be in a state a CPA will sign. Deductible expenses are those incurred in producing Panamanian income, so keep the receipt for every one.
Invoices and ITBMS
The DGI sets ITBMS at 7% on services, with 10% on alcoholic drinks and lodging. A charter with an open bar or an overnight stay should split the invoice; ask your accountant how.
Panama is moving taxpayers to electronic invoicing under Ley 256 of 2021. EDICOM, an e-invoicing provider, says that from 1 January 2026 the DGI's free invoicing tool is limited to taxpayers with up to B/.36,000 of yearly income and no more than 100 documents a month; others use an authorised provider (PAC). Confirm your obligation with the DGI.
Record platform sales at the gross amount with the commission as an expense, and ask how ITBMS applies to them. Payment methods and deposits are in charter bookings and payments.
Setting up the books for boats
A boat business has a few patterns that generic bookkeeping misses. Build them in from the start:
- One cost centre per boat. Fuel, maintenance, berth and insurance go to the boat that used them.
- Revenue by type. Charter fare, extras, bar and food, and platform sales, so each carries the right ITBMS.
- Trip records that match revenue. Each invoice should tie to a passenger list and a fuel entry; see manifests and records.
- Repairs vs improvements. A new engine or electronics may be an asset, not an expense. Ask the accountant how to treat and depreciate them.
- Payroll. Salary plus the employer's CSS contribution, 13.25% until 28 February 2027 under Ley 462 of 2025 as TVN reported, plus the décimo tercer mes in three instalments.
- Deposits. Hold advance payments as deposits until the trip runs or is cancelled under your terms.
The cost build-up behind your prices is in charter costs and pricing.
How long to keep records
Ley 52 of 2016 requires Panamanian companies, including S.A.s, S. de R.L.s and private interest foundations, to keep accounting records and supporting documents such as contracts, invoices and receipts. Kraemer & Kraemer's summary says records must be available for five years from the end of the year the transactions took place. Entities without operations in Panama keep them at the resident agent's office, or give the agent their location.
Keep crew contracts, CSS filings, AMP and ATP documents, insurance policies and claims files with the books. They are what an inspector, an insurer or a buyer's lawyer will ask for.
Owners whose boat is in charter
If a management company runs your boat, its books are not yours. Agree in the management agreement what you receive each month: bookings, revenue, expenses charged to your boat, the ITBMS collected and your share. The owner monthly report template is a starting point.
If your company owns the boat, it still owes the tasa única and must keep records even in a year without trips. How you hold the boat changes these duties; see personal, S.A. or foundation. The Florida version of this page, boat business accounting, covers US practice for owners with both.
Your practical starting checklist
- Hire a Panamanian accountant (CPA) who knows tourism or marine businesses.
- Get the RUC and register for ITBMS before the first sale.
- Set up electronic invoicing through the DGI tool or an authorised provider.
- Create a cost centre for each boat and revenue lines for fare, extras and bar.
- Tie every invoice to a passenger list and a fuel entry.
- Diary the ITBMS, income tax, aviso, tasa única and CSS deadlines.
- Keep books and supporting documents for at least five years.
