Tax compliance

We make sure your numbers match your account statements, reports and records, with enough evidence to back them up before the SII.

Portfolio consolidation
Your information stays unified and organized, even when you invest across different instruments, brokers or currencies. Every transaction is traceable, clear and documented.

Cost basis + accounting consistency

Your costs, gains and exchange rates are calculated with consistent, repeatable criteria. That prevents discrepancies from one year to the next and removes any doubt about how the reported result was reached.

Foreign investments + DJ 1929

If you hold accounts or assets abroad, the SII already knows about them through the international exchange of information (CRS). We prepare your DJ 1929 with full supporting documentation and apply tax credits and treaties so you pay only what's fair.

Sworn statements + annual support file

You get an orderly year-end close, with sworn statements (DDJJ) that match your transactions and a complete support file. Lower risk of amended returns, SII observations or penalties.
Built for investors

If your portfolio holds more than one instrument, this is for you

Ideal for individuals and companies that invest in stocks, funds, bonds, deposits, stock market transactions or derivatives, in Chile and/or abroad, and need to comply with the SII without improvising.

I have investments in Chile and/or abroad

We consolidate your multi-country portfolio and make everything consistent for reporting in Chile.

I use one or more brokers / brokerage firms / banks

We bring statements and reports from different platforms together in a single control system.

I receive dividends or interest, or sell frequently

We organize your income and transactions to calculate results with no errors or omissions.

I want to avoid discrepancies, amended returns or fines

We catch inconsistencies before the year-end close and reduce your risk with the SII.

I need accounting support and a traceable calculation

We back the calculation with clear evidence: statements, records and an annual file.
What we solve

The problem isn't investing, it's reporting without order or documentation

When your portfolio diversifies, new obligations appear: correct cost basis, accounting consistency, sworn statements and traceability. We leave everything closed out and defensible.

What usually goes wrong in diversified portfolios

Incomplete historical costs
Inconsistent exchange rates across reports
Missing or mishandled fees
Misclassified “special” transactions
Information scattered across multiple platforms
The SII already knows you invest abroad. The question is whether you reported it first.

What we do at NSS

We organize all your data in a tax-ready format
We calculate results using sound technical criteria
We prepare sworn statements and leave the documentation audit-ready
Full portfolio, full compliance

We cover every typical instrument in a diversified portfolio

From simple investments to complex transactions: we classify your portfolio by instrument type and follow a clear methodology so you file on time and with full support.

Sworn Statement 1929: if you invest outside Chile, the SII already knows

Since Chile adopted the CRS, every September the SII receives information on the accounts of Chilean residents from 96 countries. Your investments, accounts and assets abroad are no longer invisible: if you don't report them in the DJ 1929, the risk isn't hypothetical. It's an audit with fines, interest and inflation adjustments.

The good news: reporting correctly doesn't mean paying more. Using credits for taxes paid abroad and double taxation treaties, we get your international investments in order, and you pay only what's fair.

You live in Chile and have accounts or investments in your home country. As a resident, you may have to report them, even if you're a foreign national.

You're Chilean with investments abroad (stocks, crypto, funds, real estate, companies). The SII cross-checks them against your Form 22.

You've already received an SII notice or audit. We can get you compliant and reduce the impact before it escalates.

FAQs

Frequently asked questions

Does this work if I invest both personally and through a company?

Yes. In fact, it's one of the cases where discrepancies show up most often if cash flows, costs and documentation aren't kept separate.

Can you work with foreign brokers?

Yes. We standardize reports even when they aren't ready to be processed in Chile.

What if I have a very large number of transactions?

We work in stages: first what's urgent (year-end close and sworn statements), then we optimize the rest.

Can you help if I already filed and think it's wrong?

Yes. We can review it for consistency and prepare an amended return if needed.

Does this include accounting or only sworn statements?

It depends on your case. We can handle one-off compliance only, or integrate it with tax accounting.

Do I have to report my foreign investments even if they didn't generate gains?

Yes. The DJ 1929 requires you to report your foreign investments even if they produced no income during the year. Leaving them out exposes you to fines and interest.

Can the SII really see my accounts abroad?

Yes. Through the CRS, the SII receives information every year on the accounts of Chilean residents from 96 countries. The information is already in its hands; what defines your situation is whether you reported on time.
