Monthly tax obligations for a company in Chile: F29, payroll and accounting

Incorporating a company and starting activities in Chile is only the beginning. From the following month, the company is subject to a calendar of monthly obligations that apply regardless of whether there was any income in the period — they exist either way, and filing late generates fines and interest that accumulate with each additional month.

Form 29 (F29): the core of monthly compliance

The F29 is the Monthly Declaration and Simultaneous Payment of Taxes. It’s filed every month, generally within the first twelve business days of the following month, and bundles several obligations into one filing:

• VAT, calculated as the difference between output tax (VAT on sales) and input tax (VAT on purchases).
• Provisional Monthly Payments (PPM), an advance against the annual income tax, calculated as a percentage of the month’s sales.
• Withholdings, when the company pays fees to independent contractors or wages subject to withholding.

The F29 must be filed even if there were no sales or purchases in the month. A “zero” filing is still a mandatory filing.

Payroll: a separate front

If the company hires staff, payroll triggers its own set of obligations, running in parallel to the F29:

• Calculating and paying pension and health contributions.
• Declaring and paying unemployment insurance, where applicable.
• Issuing payslips and maintaining the payroll ledger.
• Withholding second-category single tax when an employee’s income exceeds the tax-free bracket.

These obligations have their own deadlines, generally within the first ten to twelve days of the following month, and are managed with different institutions than the SII — pension fund administrators (AFP), health insurers (Isapre or Fonasa), workplace insurance providers, among others — which requires coordination beyond the F29 alone.

Accounting records

Beyond the filings themselves, the company must maintain full or simplified accounting, depending on its tax regime, including the purchase and sales ledger, the general ledger, and the payroll ledger where applicable. This isn’t a formality: it’s what supports every F29 filed and what the SII reviews in the event of an audit.

Form 22: the annual reckoning

Once a year — typically in April — the company files Form 22, the annual income tax return. That’s where what was paid monthly through PPM is reconciled against the actual annual tax determined: the result can be a balance due or a refund, depending on how the business performed during the year.

Common first-year mistakes

• Filing a “zero” F29 without checking whether it was actually accurate, when there were in fact transactions that weren’t recorded in time.
• Falling behind on pension contributions by prioritising VAT payment, when both obligations run in parallel and generate independent penalties.
• Not reconciling input tax credit against purchase invoices received, creating differences that take time to correct later.
• Underestimating the first Form 22, especially when the company received capital contributions from abroad that need to be properly documented and backed by the corresponding banking records.

Why it pays to get this right from month one

Monthly compliance isn’t a task separate from incorporation — it’s its direct continuation. A company that’s well incorporated but lacks an orderly accounting and payroll process usually ends up amending filings retroactively, which costs more time and money than getting it right from the start.
