Common mistakes in the tax management of construction companies:
Error 1: Not keeping project accounting. Many small construction companies manage their numbers from various projects "mixed" in a single accounting. This not only makes it difficult to see the actual profitability by project, but it also violates Standard 07-07, which requires separating the operating results of each work.. Consequence: In an audit, the DGII can challenge expenses if they cannot be allocated to a specific project, and may even impose fines for inadequate accounting records.. Prevention: Use an accounting system with cost centers by project and discipline in the coding of each transaction. An ERP like Odoo makes this easy by allowing you to define each project and associate invoices, purchases, and payments with it from the start. Thus, at the end of the period, you can present clear information, and the DGII will be satisfied with the structure of your books..
Error 2: Forgetting to request the asset tax exemption. As we mentioned earlier, the law allows construction companies to exclude the investment in ongoing projects from the calculation of the Asset Tax, but it is not automatic: it must be requested formally within the established deadline. Consequence: If you do not apply for the exemption (or miss the deadline), your company will have to pay 1% annually on those assets in process, which in a large project can amount to millions of pesos in avoidable taxes. Additionally, not requesting the exemption could raise red flags with the DGII regarding your overall compliance.. Prevention: Keep a reminder for each new project. A good ERP allows you to record the project start date and schedule alerts 120 days in advance, along with the list of necessary documents for the DGII. ERPly CONly, for example, automates the generation of the cost estimate for the exemption, making it easier for you to submit your request on time.. Basically, the system ensures that you take advantage of the benefits that the regulation provides and avoid overpaying due to negligence..
Error 3: Tratar incorrectamente el ITBIS de las compras de materiales. Uno de los errores más típicos es llevar el ITBIS pagado en materiales como crédito fiscal normal. El departamento de contabilidad, por inercia, incluye todo ITBIS en las declaraciones mensuales, sin darse cuenta de que la Norma 07-07 dice que ese impuesto en realidad debe formar parte del costo de la obra. Consecuencia: Al ser detectado, la DGII reclasificará esos créditos como indebidos y le exigirá el pago del ITBIS no saldado en su momento, más recargos e intereses acumulados. Esto puede ocurrir en medio o al final del proyecto, afectando su flujo de caja cuando menos lo espera. Prevención: Eduque a su equipo contable sobre esta regla especial y, mejor aún, implemente un plan de cuentas adaptado. Un ERP localizado para RD ya viene con las configuraciones apropiadas: en Odoo, las cuentas de compras de materiales de construcción pueden estar configuradas para no computar crédito de ITBIS, asignando ese monto directamente al costo del proyecto. Así, aunque su contador lo olvide, el sistema no lo olvida – manteniendo sus declaraciones correctas por diseño.
Error 4: Do not withhold income tax on payments for informal labor. In the rush of day-to-day life, it's easy to make payments to small contractors (teachers, crew members) and overlook the 2% withholding required by law. Or perhaps your accounts payable department is unclear about when to apply 2% vs 10% and when it does not apply. Consequence: If you do not withhold, those payments may be rejected as deductible expenses in an audit, increasing your taxable income for income tax. Worse yet, the tax authority could fine you for not acting as a withholding agent.. Prevention: Establish internal protocols where no payments to individuals are issued without the corresponding withholding calculation. An ERP integrated with accounts payable simplifies this: for example, when recording an invoice from a freelance architect with their fees, the system immediately calculates the 10% to withhold before generating the payment. And if it is a construction service from a contractor without an RNC, when generating the payment, the ERP will automatically apply a 2% definitive withholding. Additionally, the system will maintain a history of all withholdings made, so that at the end of the quarter, you can declare those withholdings without omissions.
Error 5: Relying on informal invoices without controls (NCF). Although regulation 07-07 relaxes the need for NCF in certain cases, taking advantage of that flexibility without control is risky. A common mistake is paying multiple expenses in cash or to informal suppliers and not documenting them properly. For example, giving money to a foreman to buy materials and not asking for invoices, thinking that "since it's 07-07, it doesn't matter." Consequence: While you don't need NCF from adjusters for tax purposes, you do need proof of how that money was used.. The DGII could object to excessive expenses on materials without formal invoices or suspect evasion. Also, if there is no record kept, one might end up paying twice for something or not realizing discrepancies.. Prevention: Maintain strict internal controls for cash expenditures and funds given to third parties. Use internal receipts, vouchers, and invoice requirements whenever possible. At the system level, record those advances and then assign invoices or expenses to them. An ERP allows you, for example, to record an advance to a master and subsequently allocate the actual costs against that advance, attaching the evidence. Transparency and traceability in the system will deter problems and give the DGII confidence that, although there were no NCF, all expenses are justified..
Error 6: Errors in the monthly tax reports. Presenting 606/607 with inconsistencies, figures that do not match the IT-1, or uploading files with format errors are more operational but frequent failures. Many times, these arise from keeping separate accounts in Excel and then transcribing, which generates discrepancies. Consequence: DGII may impose penalties for incorrect data or send notifications requiring corrections, consuming your team's time. Repeating errors may put you under the scrutiny of audits. Prevention: Digital integration. Ensure that the generation of those reports is as automated as possible from your accounting, reducing manual intervention. Odoo, for example, generates the 606/607 based on the recorded invoices, ensuring that the totals of ITBIS and amounts match exactly with what is declared in IT-1. It also validates RNC/ID formats, preventing rejections. Investing in this automation is a way to prevent headaches and fines due to "discrepancies."”.
EError 7: Ignore new provisions or regulatory changes. The tax framework is not static; for example, electronic invoicing is already mandatory for many and will gradually become mandatory for all. If a construction company does not update and continues to issue paper receipts when it should be issuing electronic ones, it may be sanctioned. Or if it does not update its systems to reflect changes in rates (ITBIS increased to 18% a few years ago, etc.), it will incur errors. Consecuencia: Incumplimiento por desconocimiento igual trae sanción. DGII usualmente da plazos de adaptación, pero luego aplica penalidades. Prevention: Stay informed with your tax advisor or by subscribing to newsletters from the Chamber of Construction or DGII. And keep your software updated. One advantage of using Odoo with a local partner like ERPly is that regulatory updates are incorporated into the system as soon as they come into effect – for example, ERPly added the e-CF module as soon as Law 32-23 was enacted. This way, you will always be up to date without having to reinvent processes.
How Odoo ERP prevents these errors and protects your business
Avoiding all previous mistakes may sound overwhelming, but this is where a customized ERP for the Dominican environment shows its value.The Odoo platform with the vertical ERPly module for construction acts as a "guardian angel" for your tax-operational compliance.:
Embedded business rules: The system comes preconfigured for Standard 07-07, which means that from day one it helps avoid penalties from the DGII and ensures the cost control required by law. You don't have to be the one to remember every detail: the ERP already knows the rules and applies them in every transaction..
Automated validations: If you try to register something out of the norm, the system will alert you. For example, if an accountant tries to mark a purchase of rods with creditable VAT, Odoo can block it or warn that this VAT should be treated as a cost. If you forget to assign a project to an expense, the system will not allow you to proceed until you choose one (this ensures project accounting). These "small automatic touches" prevent errors before they occur..
Intelligent tax calculation: Odoo ERPly automatically calculates the amounts of ITBIS and withholdings as applicable, as we saw. This not only saves time but also eliminates the possibility of incorrect calculations. A concrete example: When generating an invoice for the sale of an apartment under a turnkey contract, the system will correctly invoice only 10% with ITBIS at 18%, that is, 1.8% of the total, as mandated by the regulation. You don’t even need to know that figure – the system does it correctly for you. The same goes for withholdings: each payment to a subcontractor includes the precise percentage, leaving no room for forgetfulness or mistakes.
Real-time reports and alerts: The ERP provides dashboards where you can monitor the status of your compliance. For example, you can see "Accumulated withholdings this month" to know how much to pay in IR-17, or "Pending project purchases for NCF" to follow up on missing documents. It also sends alerts: "5 days left until the 606 deadline" or "Project X exceeded the initially declared deadline, notify extension to DGII." It's like having a tax advisor whispering timely reminders in your ear.
IIntegration with DGII and local entities: ERPly has developed integrations to connect your Odoo with the DGII platforms whenever possible. We have already mentioned the generation of 606/607 reports ready for upload. Additionally, electronic invoicing connects with DGII to stamp your NCF instantly. In summary, your ERP acts as a bridge between your operation and the tax authority, reducing friction and ensuring that information flows correctly. An integrated system equates to a flawless execution of your obligations, without the last-minute stress.
Let's think about a real scenario: The construction company Los Prados was notified of a surprise audit by the DGII. Thanks to their ERP, they were able to deliver clear project books, ITBIS reports showing that ITBIS was never deducted from materials, and a file with all payments to teachers with the 2% withholdings applied, all within a matter of hours. The auditors were satisfied to see the level of order and compliance. No fines, no adjustments. Meanwhile, the company's manager practically "let the system speak for itself." Este nivel de confianza solo se logra cuando se han eliminado las posibilidades de error manual mediante automatización.
