To shortlist an accounting firm in Coronel Oviedo, first decide what you need (monthly tax returns, payroll, electronic invoicing or setting up a company), ask two or three firms for a written proposal stating what the monthly fee covers, and check their tax ID with the DNIT before handing over your password. And before paying anyone for tax-ID paperwork, know that the DNIT does it for free.
What will you ask the accountant to do?
- Monthly and annual returns: VAT, income tax and books in the Marangatú system of the DNIT (opens in a new tab), Paraguay's tax authority. This is any firm's core service.
- Payroll: from 1 July 2026 the minimum wage is G. 3,044,000 a month (ABC Color (opens in a new tab)). If you have staff, make sure the fee includes payroll and that they warn you about adjustments.
- Electronic invoicing: the DNIT keeps adding taxpayers in groups. General Resolution 52/2026 designated about 3,000 more, with start dates from 1 June 2026 to 1 September 2027, notifying each one through the Marandu tax mailbox; from that date their preprinted invoice authorisation expires (DNIT (opens in a new tab)). Ask the firm whether it has checked your mailbox and which group you are in.
- Setting up a company: an EAS (simplified joint-stock company) with standard by-laws can be set up online in up to 72 hours at no cost (MIC (opens in a new tab)). If yours is simple, save the accountant's fee for what comes after.
What can you do for free without a firm?
- Tax-ID (RUC) procedures: in July 2026 the DNIT reminded taxpayers that registering, updating and closing a RUC, compliance certificates and service at its offices are all free (DNIT, 2026 (opens in a new tab)). If someone charges you just to register, that is not a DNIT fee.
- Invoicing as a small taxpayer: the DNIT offers e-Kuatia'i, a free e-invoicing system used by more than 10,000 small taxpayers by November 2025 (DNIT, 2025 (opens in a new tab)).
- Questions: the DNIT call centre answers free on (021) 729 7000, Monday to Friday, 7:30 to 12:00 and 13:00 to 16:00, according to its 2023 report (DNIT (opens in a new tab)).
An accountant saves you time when you have staff, several lines of business or arrears to sort out; for a simple small business, these tools are often enough.
Why Coronel Oviedo calls for a firm that knows business clients
The city's economy grew 8% in 2024 after three years at 1% a year, according to the research department of UNCA's economics faculty, and 100 of the 213 industries registered in Caaguazú department are in Coronel Oviedo (InfoNegocios, 2025 (opens in a new tab)). Agro-industry, textiles and timber lead, and informality is listed among the challenges. If your business is industrial or sells to other companies, look for a firm that already handles clients in your sector and knows business-to-business invoicing, not just small taxpayers.
The city is also the seat of the Caaguazú and San Pedro judicial district (Law 96/91 (opens in a new tab)). If your case could end in a labour claim or debt collection, choose a firm that works with a lawyer registered with the Supreme Court (opens in a new tab).
How to check the firm before hiring
- Valid tax ID: the DNIT's no-login services (opens in a new tab) let you see any taxpayer's RUC profile and validate a compliance certificate.
- Not barred: the DNIT publishes lists of barred businesses and taxpayers in arrears (DNIT (opens in a new tab)). Whoever does your taxes shouldn't be on them.
- An invoice for every payment: every sale of services requires one (Sedeco via ABC Color (opens in a new tab)).
- Your password is yours: put in writing that the Marangatú password belongs to you, and change it if you switch firms.
What to ask for in the proposal
- What the monthly fee covers: returns, books, payroll, amended filings.
- What costs extra, and how much: annual statements, clearing arrears, switching to e-invoicing.
- How they will remind you of deadlines and how fast they reply.
- A short monthly report: sales, purchases, taxes paid and upcoming deadlines.
