Point CARF tools file a report and stop. Here's the case for CARF/DAC8, withholding, and a retail tax centre on one data layer, at a fraction of the cost.
Every crypto venue in scope for CARF and DAC8 is about to buy software for it. The default assumption is that you buy a reporting tool, one that ingests transactions and emits a filing. That works. But it's worth asking what else the same data can do before you sign, because the reporting file is only one obligation among several that run on identical inputs.
At minimum, ingest transactions across chains and venues, run CARF due diligence, generate valid CARF XML plus any national formats, and validate before filing. The larger question is whether the same data also drives withholding, a retail tax centre, and audit, or whether you buy those separately.
It is if filing is your only obligation. If you also have to withhold tax at source, serve retail users a tax centre, or support an audit, a single platform on one data layer usually costs less and integrates once, versus buying and wiring several point solutions.
It varies widely. Multi-vendor, reporting-only setups for large exchanges can reach six or seven figures a year once withholding and retail tax are added. Kryptos is a flat fee starting at $15,000 a year for the full platform; current tiers are on the pricing page.
Austrian providers must withhold 27.5% KESt on crypto gains. Here's what triggers it, how the moving-average basis works, and how to automate the filing.
Withhold KESt at source and your users' crypto tax is final, no return needed. Use a foreign provider and they self-declare. Here's why the difference matters.
Austria requires the gleitender Durchschnittspreis for crypto, not FIFO. Here's how the moving-average basis works and why it complicates withholding.

A point solution files your CARF and DAC8 reports and stops. But the reconciled, per-user, per-jurisdiction dataset you built to file is the same dataset you need to withhold tax at source, to give retail users a tax centre, to track portfolio and treasury positions, and to satisfy an audit. Buy a tool for each and you integrate the same data four times and pay four vendors.
Reporting and withholding are the clearest example. In Austria, a domestic provider has to withhold 27.5% KESt and file CARF, and both run off the same classified transaction feed. Our tax withholding solution and our CARF and DAC8 reporting share one ingest, so you cover both from a single integration instead of standing up a second stack. Add a white-label tax centre for your retail users from the same data, and the compliance spend starts earning its keep on the product side too.
This isn't only an architecture argument. Multi-vendor reporting-only setups for a large exchange run into the high six and seven figures a year once you add withholding, retail tax, and audit tooling from separate providers. Kryptos is a flat fee that starts at $15,000 a year and covers the platform end to end. You can see the tiers on our pricing page.
If all you'll ever need is a filing, a reporting-only tool is fine. If you also have to withhold, serve retail users, or answer an audit, weigh the platform. A practical test: ask each vendor what happens to the data after the report is filed. If the answer is "nothing," you're paying to build the same pipeline again for the next obligation.
