ERR_REPORT

CLEAN_DATA

Common Tax Tool Problems

These errors occur across all tools – whether Blockpit, CoinTracking, Koinly, CoinTracker or Awaken Tax.

Deep Dive

The tool calculates. The crypto documentation decides.

Blockpit, CoinTracking and others calculate correctly. That's not the problem. They can only produce correct results if the crypto documentation is accurate. Missing transactions, wrong labels or duplicates in the raw data end up directly in the tax report. Switching tools doesn't solve the problem.

Request Check

01_MISSING_DATA

Missing Transactions

APIs don't deliver everything. DeFi interactions, airdrops or old exchange data are often completely missing from the tool.

02_CLASSIFICATION

Incorrect Classification

Swaps as sales, staking as deposits, bridges as trades – wrong labels distort the entire report.

03_COST_BASIS

Missing Cost Basis

Cost basis 0 EUR for almost every trade? Missing incoming transactions destroy the entire profit calculation.

04_DUPLICATES

Duplicates and Double Imports

CSV import plus API sync create duplicate transactions. This massively distorts profits and balances.

05_BALANCE

Negative Balances and Balance Errors

According to the tool, you're selling more than you own? Missing incoming transactions or incorrect wallet assignments are the cause.

06_SCAM_DUST

Scam Tokens and Dust Transactions

Unwanted token airdrops and dust attacks appear in the report as taxable transactions.

The Value of Tax Tools

Why crypto tax tools are indispensable

The tax authority requires comprehensible crypto documentation. Tax tools are the central instrument for this.

Automatic Categorization

Tax tools automatically recognize trades, staking rewards, airdrops and transfers and classify them correctly for tax purposes – provided the underlying data is correct.

Tax Report at the Push of a Button

A clean tax report is generated automatically once the crypto documentation is complete and correct in the tool. No manual calculations needed.

Tax Authority-Compliant Documentation

Tools generate reports that are accepted by tax authorities – with comprehensible cost basis, correct holding period calculations and complete transaction history.

Real-Time Portfolio Overview

In addition to tax calculations, tools provide a consolidated overview of all wallets, exchanges and DeFi positions. However, this requires complete crypto documentation.

From Practice

Where most people fail

Tax tools are powerful – but only as good as the data you put in.

"All APIs connected, yet incorrect profits."

Typical: APIs don't export all transaction types. DeFi interactions, internal transfers and historical data are often left out.

"200+ warnings, don't know where to start."

Typical: Warnings and notices in the tool are symptoms, not causes. Often a single missing wallet connection triggers hundreds of follow-up errors.

"Missing cost basis for almost every trade."

Typical: Missing incoming transactions mean: the tool doesn't know the purchase price. Without cost basis, every sale is calculated as 100% profit.

"Tried 3 tools, different numbers everywhere."

Typical: Different import states, various classification logics and diverging data sources produce different results. The crypto documentation must be identically prepared in every tool.

Frequently Asked Questions About Tax Tool Errors

Which crypto tax tools does TX-Partner support?

The focus is on Blockpit and CoinTracking – the two most used tools in the DACH region. Koinly, CoinTracker and Awaken Tax are also supported on request. The methodology is tool-agnostic: TX-Partner corrects the crypto documentation, not the tool itself.

Is TX-Partner the official support of a tax tool?

No. TX-Partner is an independent documentation service. For technical tool questions (e.g. software bugs, login issues or feature requests), please contact the respective tool support directly.

How long does correcting the crypto documentation take?

Depending on portfolio scope and complexity, a complete correction usually takes 2 to 6 weeks. TX-Partner creates a timeline in advance and keeps you updated on progress.
