Arithmetic check of band bases:
Top of 15% band: (624,329.00 − 416,220.01) × 15% = 208,108.99 × 0.15 = RD$31,216.35 ≈ RD$31,216 ✓
Top of 20% band: 31,216 + (867,123.00 − 624,329.01) × 20% = 31,216 + 242,793.99 × 0.20 = 31,216 + 48,558.80 = RD$79,774.80 ≈ RD$79,775 (DGII publishes the next-band base as RD$79,776 owing to rounding) ✓
Annual exempt threshold FY2025 — RD$416,220 DOP (inflation-indexed each year (up ~4.2% from FY2024's RD$399,923)) ([PwC; DGII Comunidad de Ayuda CA687])

Input line:
15/03/2025 ; BANRESERVAS TRANSFERENCIA RECIBIDA ; CONSTRUCTORA DEL CARIBE SRL ; PAGO FACT B0100000045 ; +106,200.00 ; DOP
Reasoning: Client payment for professional services. Provider is ITBIS-registered, so the gross billed was net + 18% ITBIS. If the RD$106,200 received already reflects the invoice net of any ISR withholding, confirm the certificación de retención. Assume the bank credit is the cash received and the underlying invoice net of ITBIS is the business income line.
Classification: Business income = RD$90,000 (net of ITBIS). ITBIS RD$16,200 excluded. Note any 10% ISR withheld by the payer as a credit against the annual ISR.
Input line:
01/04/2025 ; POPULAR DÉBITO AUTOMÁTICO ; ADOBE SYSTEMS ; CREATIVE CLOUD ABR ; -1,770.00 ; DOP
Reasoning: Monthly SaaS subscription, recurring, business use. Fully deductible operating expense. ITBIS on imported digital services may apply separately; for income tax the business cost is the net charge.
Classification: Deductible business expense = RD$1,770 (or net of recoverable ITBIS if registered and reclaimable).
Input line:
22/04/2025 ; BHD TRANSFERENCIA ; JUAN PÉREZ (abogado) ; HONORARIOS ASESORÍA ; -50,000.00 ; DOP
Reasoning: Payment for professional services to an individual. Deductible expense, but the payer has an obligation to withhold 10% ISR (RD$5,000) and remit it on Form IR-17 by the 10th of the following month [Decreto 139-98]. If the RD$50,000 is the net paid after withholding, gross fee = RD$55,555.56 and RD$5,555.56 withheld; if RD$50,000 is the gross fee, RD$5,000 should have been withheld and RD$45,000 paid. Confirm the contract basis.
Classification: Deductible expense (gross fee). Flag the 10% IR-17 withholding obligation for the reviewer.
Input line:
30/04/2025 ; POPULAR ABONO ; NÓMINA EMPRESA XYZ SRL ; SUELDO ABRIL ; +60,000.00 ; DOP
Reasoning: Employment income. The employer withholds ISR monthly via the annualized scale and reports on Form IR-3. No tax is due until annualized salary exceeds RD$416,220 (~RD$34,685/month) [P&H Law; DGII]. A purely salaried person whose wages are fully withheld generally need not file IR-1. This is NOT self-employment income.
Classification: Employment income (separate stream). Exclude from self-employed business income; confirm withholding via the employee's payslip.
Inputs: Self-employed consultant, DR-resident, RNC-registered. Gross professional income RD$1,200,000; deductible business expenses RD$300,000; not SDSS-affiliated.
Reasoning:
Classification: IR-1 net taxable income RD$900,000; ISR before credits RD$87,995.25; ISR due after withholding credit RD$57,995.25.
Input line:
15/05/2025 ; BHD TRANSFERENCIA ; CUENTA PROPIA - AHORROS ; ; -100,000.00 ; DOP
Reasoning: Transfer between the client's own accounts. Neither income nor expense. Exclude entirely.
Classification: EXCLUDE.
5.10 ITBIS (VAT) Interaction
| Scenario | Income Tax Treatment |
|---|---|
| ITBIS collected on sales (registered) | NOT income -- exclude from business income |
| Input ITBIS recovered (registered) | NOT an expense -- exclude from deductions |
| Input ITBIS blocked/non-recoverable | IS an expense -- include gross |
| Unregistered for ITBIS | Gross amounts paid are the cost |

Input: DR resident, gross professional income RD$1,200,000, deductible expenses RD$300,000, no SDSS, no withholding suffered. Expected: Net taxable income RD$900,000. ISR = 79,776 + 25% × (900,000 − 867,123.01) = 79,776 + 8,219.25 = RD$87,995.25. ISR due RD$87,995.25 (no credits).
Input: Net taxable income RD$700,000. Expected: ISR = 31,216 + 20% × (700,000 − 624,329.01) = 31,216 + 20% × 75,670.99 = 31,216 + 15,134.20 = RD$46,350.20.
Input: Net taxable income RD$500,000. Expected: ISR = 0 + 15% × (500,000 − 416,220.01) = 15% × 83,779.99 = RD$12,567.00 (RD$12,566.9985 rounded).
Input: Net taxable income RD$400,000. Expected: RD$400,000 ≤ RD$416,220 exempt threshold → ISR = RD$0.
Input: Net taxable income RD$900,000 (ISR before credits RD$87,995.25); RD$30,000 ISR withheld at source on honorarios. Expected: ISR due on IR-1 = 87,995.25 − 30,000 = RD$57,995.25.
Input: Monthly salary RD$50,000, below AFP/SFS ceilings (Feb-2026 set). Expected: Employee deduction = 5.91% × 50,000 = RD$2,955 (2.87% AFP = RD$1,435 + 3.04% SFS = RD$1,520). Employer cost ≈ 16.39% × 50,000 = RD$8,195 (subject to SRL 4× ceiling check) [PwC; TSS].
Input: Gross fee RD$55,555.56 paid to an individual lawyer. Expected: Withhold 10% = RD$5,555.56 on Form IR-17; pay net RD$50,000.00. Expense deductible at gross RD$55,555.56.

Minimum viable inputs
bank statement for the full tax year in CSV, PDF, or pasted text, plus confirmation of (a) residence status, (b) whether the person is salaried, self-employed, or both, and (c) RNC registration status.
Recommended inputs
all sales invoices (comprobantes fiscales / NCF), purchase invoices/receipts, evidence of ISR withheld by payers (certificaciones de retención), TSS contribution records (if affiliated), prior-year IR-1 or assessment, ITBIS registration status.
Ideal inputs
complete income and expenditure account, asset register with depreciation schedule, monthly IR-3/IR-17/IT-1 filings, withholding certificates, and regalía pascual records.
Refusal if minimum is missing
SOFT WARN. No bank statement at all = hard stop. Bank statement without invoices = proceed with reviewer warning: "This IR-1 was produced from bank statement alone. The reviewer must verify that all deductions claimed are supported by valid fiscal receipts (NCF) and that the income is wholly DR-source business/professional income."
R-DO-1 -- Residence / source uncertain
"Dominican Republic uses a territorial system, and the taxation of foreign-source income depends on residence facts and the 3-year rule for newly-resident individuals. This skill cannot determine residence. Please confirm before proceeding, or escalate to a Dominican CPA."[PwC]
R-DO-2 -- Companies / partnerships
"This skill covers individuals and sole proprietors (personas físicas) only. Sociedades and other personas jurídicas file the IR-2 corporate return under different rules. Escalate to a Dominican CPA."
R-DO-3 -- Foreign-source income / expatriates
"Foreign-source investment income of a newly-resident individual is generally only taxed from the 3rd year of residence, and treaty relief may apply. Out of scope. Escalate to a Dominican CPA."[PwC]
R-DO-4 -- Capital gains / asset disposals
"Capital gains computations require specialised analysis under the Código Tributario. Escalate to a Dominican CPA."
R-DO-5 -- Arrears / enforcement
"Client has outstanding ISR or SDSS arrears or is subject to DGII/TSS enforcement. Surcharges of 10% (first month) + 4%/month plus 1.10%/month interest compound quickly. Do not advise. Escalate to a Dominican CPA immediately."[DGII]
R-DO-6 -- ITBIS (VAT) return requested
"This skill covers income tax (ISR / IR-1) only. For Dominican ITBIS, use the dominican-republic-itbis skill (Form IT-1)."

Territorial system and residence
The Dominican Republic uses a **territorial** system: residents are taxed on DR-source income. Foreign-source investment/financial income of a newly-resident individual is taxed only **from the 3rd year of residence**. Default to DR-source income unless residence facts indicate otherwise [PwC].Código Tributario (Ley 11-92); PwC
Progressive ISR scale application
Apply the Section 1 scale: 0% up to RD$416,220; 15% on 416,220–624,329; base RD$31,216 + 20% on 624,329–867,123; base RD$79,776 + 25% above 867,123. Top marginal rate 25%. The exempt threshold is inflation-indexed annually [PwC; DGII].PwC; DGII
Tax year and filing
Tax year is the calendar year ending 31 December. Individuals / sole proprietors file **Form IR-1** by **31 March** of the following year. Salaried employees with only fully-withheld wages generally need not file [DGII].DGII
Employee withholding
Employers withhold ISR monthly using the annualized scale (no tax until salary exceeds ~RD$34,685/month) and report on **Form IR-3 by the 10th** of the following month, even if nil [P&H Law; DGII].P&H Law; DGII
Deductibility of business expenses
Expenses incurred to obtain, maintain, or conserve taxable income are deductible if supported by a valid fiscal receipt (NCF). Personal, entertainment, fines, drawings, and the income tax itself are not deductible. Mixed-use expenses must be apportioned on a reasonable, documented basis.
SDSS for dependent workers
For salaried workers, the employer withholds the employee SDSS share (**5.91%** = 2.87% AFP + 3.04% SFS) and pays the employer share (**~15.39%** = 7.10% AFP + 7.09% SFS + ~1.20% SRL) plus **1% INFOTEP**, each subject to its component ceiling [PwC; TSS]. Use the ceiling set matching the contribution month (Section 1).PwC; TSS
Self-employed and SDSS
Self-employed and independent professionals are **NOT mandatorily** enrolled in SDSS (the TSS mandatory contributory regime applies to dependent workers). They may affiliate **voluntarily** to access pension (AFP) and health (ARS/SFS) benefits. Do not auto-apply employee SDSS deductions to a pure freelancer unless they have opted in [TSS Preguntas Frecuentes].TSS Preguntas Frecuentes
RNC registration
Any person carrying on business or independent professional/commercial activity must register with DGII to obtain an **RNC** (Registro Nacional del Contribuyente). Registration is free (~25 days). There is no de-minimis turnover threshold for RNC for business activity [DGII; BizLatin Hub].DGII; BizLatin Hub
Withholding on payments to individuals
When the client **pays** an individual, withholding obligations arise: **10%** on professional services (honorarios) and rentals; **2%** on technical services; remitted on **Form IR-17 by the 10th** of the following month [Decreto 139-98; P&H Law].Decreto 139-98; P&H Law
5.10 ITBIS (VAT) Interaction
| Scenario | Income Tax Treatment | |---|---| | ITBIS collected on sales (registered) | NOT income -- exclude from business income | | Input ITBIS recovered (registered) | NOT an expense -- exclude from deductions | | Input ITBIS blocked/non-recoverable | IS an expense -- include gross | | Unregistered for ITBIS | Gross amounts paid are the cost |
ITBIS standard rate and reverse-perception
ITBIS standard rate is **18%** (16% reduced on certain foods). Registered persons file **Form IT-1 by the 20th** of the following month. A **18% reverse-perception** applies on operations over **RD$300,000** with unregistered/suspended-RNC providers (Norma General 06-23) [DGII; EY].DGII; EY
Regalía Pascual
Mandatory: 1/12 of total ordinary salary earned in the calendar year, paid by **20 December**. The legal twelfth is **ISR-exempt**; INFOTEP takes **0.5%** from the bonus [Labor Code; INFOTEP].Labor Code; INFOTEP
5.12 Filing Deadlines and Penalties
| Item | Detail | |---|---| | IR-1 (individual annual ISR) | 31 March of following year [DGII] | | IR-3 (monthly employer ISR withheld) | 10th of each month, even if nil [DGII] | | IR-17 (other ISR withholdings / services / rentals) | 10th of the following month [DGII] | | IT-1 (monthly ITBIS) | 20th of the following month [DGII] | | TSS planilla (Autodeterminación SDSS) | First working days of the following month [TSS] **[RESEARCH GAP -- reviewer to confirm exact window]** | | Late-payment surcharge (recargo) | 10% for the first month + 4% per additional month or fraction [DGII] | | Indemnizatory interest | 1.10% per month (or fraction) on the unpaid balance [DGII] | | Late filing | Surcharge/interest on tax due; additional fixed fines possible under the Código Tributario [DGII] | | Late/non-payment of SDSS (TSS) | Recargos and interest per TSS rules; collection actions and employer liability [TSS] |
Home office deduction
- Calculate the proportion of the home used for business (dedicated room(s) as a percentage of total area). - Apply that percentage to rent, electricity (EDESUR/EDENORTE/EDEESTE), water, internet. - Must be a genuinely dedicated workspace; a dual-use room does not qualify. **Conservative default:** 0% until the reviewer confirms the arrangement. **Flag for reviewer:** confirm floor-area basis and supporting NCF.
Motor vehicle business use
- Only the business-use percentage of fuel, insurance, maintenance, and depreciation is deductible. - Client must maintain a mileage log (business vs total). **Conservative default:** 0% business use until a mileage log is provided. **Flag for reviewer.**
Phone / internet mixed use
- Business-use portion only (CLARO/ALTICE/VIVA). Client must provide a reasonable estimate. **Conservative default:** 0% until business percentage confirmed.
Bad debt write-off
Deductible only if income was previously declared, recovery steps were taken, and the debt is genuinely irrecoverable. Flag all three for the reviewer.
Depreciation of capital assets
Capital items must be depreciated over their useful life under the Código Tributario rather than expensed. **[RESEARCH GAP -- reviewer to confirm]** the applicable category and rate (Art. 287 asset categories). Do not assume a rate.
Voluntary SDSS affiliation for the self-employed
If a freelancer has voluntarily affiliated, contributions are based on a declared income and may be partly deductible. Confirm the affiliation basis, the cotizable income, and the rates actually applied with the TSS.
Foreign-source income and the 3-year rule
For a newly-resident individual, foreign-source investment/financial income is taxed only from the 3rd year of residence. Flag the residence start date and income source for the reviewer [PwC].PwC
