Designed to comply with Chilean regulations before SII

Full compatibility with the unique information requirements of the SII, including specific rules for each Tax Regime — for personal trading, mining,

Initial consultation

Objectives and analysis of the customer's current structure
Current customer

We start by understanding what you hold and what you did with it: bitcoin purchases and sales, swaps between coins, stablecoins such as USDT, staking, airdrops or mining. Each movement is taxed differently.

Optimize the tax burden through expenses, reinvestments, deferral, exemptions and effective tax savings.

So you can access your gains and reinvest them wherever you want: other assets, property, paying down debt or funding your next project.

Week 1-2

Order of the cryptoasset business model

We consolidate your history from wherever it lives — Binance, Buda, CryptoMKT or your own wallet — and rebuild the cost basis. That is where the capital gain on your bitcoin or ethereum sales shows up, along with the swaps that triggered tax without ever touching pesos.

Determination of the legal structure to be created

You sign the contract digitally and pay the initial fee.

Constant support

Tax burden optimization

We choose the cost method that suits you best and apply it consistently across the whole portfolio — bitcoin, ethereum, stablecoins and the rest — using criteria we have already defended before the SII.

Monthly and annual accounting

Tax and accounting maintenance

Monthly F29, annual F22 and the source-of-funds reports banks ask for when you cash out to pesos. If you hold balances on exchanges outside Chile, we also check whether the DJ 1929 applies.

FAQs

We have the answers

How do I get started?

Get in touch so we can get to know each other. We want you to understand the structures, why experience in this field matters, and to hear about your goals.

When should I start?

We recommend — for several reasons — getting advice a few months before making any move that triggers taxes (for example, selling or swapping crypto).

Why you and not other lawyers?

Because we understand crypto assets and we also help you diversify and reinvest intelligently. Our advice doesn't stop at crypto.

Are you safe? Are you certified?

NSS was the first firm in Chile to specialise in crypto asset taxation. We have more than 5 years of experience and several million USD optimised for our clients.

How do you charge?

We have specific plans for this. There is generally an initial fee and then a fee to maintain the structure.

How much tax can I optimise?

With good planning, we achieve around a 30% reduction in the tax burden. Our advisory averages a 7x-10x ROI, and more in some cases.

Can I use your invoices as an expense?

Yes. Our services qualify as deductible expenses that you can use to reduce your tax burden.

Can I pay by credit card?

Yes, you can pay by credit card through Webpay, and we usually offer instalments.

Do I pay tax if I swap USDT for bitcoin without converting to pesos?

Yes. A swap between cryptocurrencies is a disposal: a capital gain is determined even if you never convert to pesos. It is one of the points where we most often see a gap between what was reported and what should have been.

How are staking, airdrops and mining taxed?

They are different events and are reported differently. What they have in common is that they generate income at the moment you receive them, with a cost basis that later determines the result when you sell. We review each case.

Do I have to report my cryptocurrencies if I haven't sold them?

Holding them does not generate income tax on its own. But if they sit on an exchange outside Chile, you may need to report them in the DJ 1929.

Does this work if my exchange is outside Chile?

Yes. We work with exports from Binance, Kraken, Coinbase and any platform that produces a CSV, as well as your own wallets.
