TokenTax API keeps failing to sync my Binance trades

Your Binance API permissions probably got reset. Binance does this randomly, especially after any "security update" they push.Go to Binance API Management, delete your old key, create a new one with "Enable Reading" checked. **Do not** check "Enable Trading" - TokenTax doesn't need it and Binance will block the connection.Wait 5 minutes after creating the key (Binance lag), then reconnect in TokenTax. If it still fails, try the connection at 3am when Binance traffic is lower.

My DeFi transactions show up as "Unknown Transaction Type"

TokenTax's DeFi recognition breaks on newer protocols. Here's what actually works:Manual categorization is faster than waiting for their "algorithm improvements." Export your transactions to CSV, find the unknowns, and manually tag them:- Uniswap LP deposits = "Add Liquidity"- LP withdrawals = "Remove Liquidity"- Farming rewards = "DeFi Income"- Flash loan arbitrage = "Trade" (both legs)Save the CSV and re-import. Takes 20 minutes vs waiting months for TokenTax to fix their recognition.

TokenTax is calculating ridiculous tax amounts - showing $50k owed on $5k gains

This is their pricing oracle going insane. Happened to me in March 2025 when some LP tokens got valued at $47,000 each instead of $47.Don't panic. Go to Portfolio Review, sort by "Unrealized Gains" descending. You'll see the phantom millions immediately.Click each ridiculous entry, hit "Edit Price," and manually fix it using [CoinGecko historical prices](https://www.coingecko.com). TokenTax will recalculate everything in real-time.

CSV import keeps failing with "Format Error"

TokenTax's CSV parser is picky as hell. Use their exact template format:Download their "Universal Template" from the import page. Don't modify column headers. Don't add extra columns. Don't change date formats.If you're importing from another platform (Koinly, CoinTracker), export as "Generic CSV" not their native format. Other platforms add extra metadata that breaks TokenTax imports.

API rate limits are blocking my transaction imports

Every exchange has different rate limits. TokenTax hits them during tax season when everyone's importing at once.**Immediate fix:** Disconnect all APIs, wait 24 hours, reconnect them one at a time with 10-minute gaps. I know it's annoying.**Better fix:** Export CSVs manually from each exchange. Slower but bypasses rate limits entirely. Use this for tax season crunch time.

My margin trading P&L is completely wrong

TokenTax calculates margin positions weirdly. It treats borrowed funds as "purchases" which inflates your cost basis.Export your margin trades to CSV. You'll see separate entries for "Borrow USDT," "Buy BTC," "Sell BTC," "Repay USDT." Delete the borrow/repay entries - only keep the actual trades. Re-import.This fixes 90% of margin calculation errors. For complex perpetuals, honestly just use a spreadsheet.

TokenTax is missing half my MetaMask transactions

TokenTax's Ethereum scanner sometimes skips transactions during high gas periods. They prioritize "obvious" trades and miss internal calls.Connect your MetaMask using the wallet address method, not CSV. Go to Portfolio → Add Wallet → paste your address. TokenTax will rescan the entire wallet history from block 1.This takes 2-6 hours for active wallets but catches everything their API missed. For faster results, use a date range starting from your first DeFi transaction.

My staking rewards are showing up as regular income instead of capital gains

TokenTax defaults to treating all staking as income at fair market value when received. This kills you on taxes if you're staking significant amounts.Go to Settings → Tax Settings → "Staking Treatment" → Change to "No taxation upon receipt." This treats staking rewards like stock dividends - no taxes until you sell.**Warning:** This is aggressive tax treatment. Some CPAs disagree with this interpretation. If you're audited, be ready to defend it with precedent cases.

TokenTax can't handle my Binance margin liquidation properly

Liquidations are messy because Binance force-closes positions at market prices, often creating artificial gains/losses that don't reflect your actual P&L.Export your Binance margin history manually. Look for "Liquidation" entries. These should be marked as "Forced Sale" in TokenTax, not regular trades.Edit each liquidation transaction: Change type from "Trade" to "Liquidation Loss" (if you lost money) or keep as "Trade" (if somehow profitable). This prevents phantom gains from appearing in your tax calculation.

My NFT sales are calculated wrong - showing gains when I clearly lost money

TokenTax often miscalculates NFT cost basis because it doesn't account for creator royalties, gas fees, or marketplace fees properly.For each NFT sale: Check the "Purchase Price" TokenTax calculated. Add gas fees from your original mint transaction. Add marketplace fees (usually 2.5% on OpenSea). Add any royalties paid to creators.Your actual cost basis is mint cost + gas + all fees. If TokenTax calculated lower, edit it manually. This usually flips losses to proper reporting.

TokenTax keeps timing out when processing my large portfolio

Their servers can't handle portfolios over 25,000 transactions reliably. The import starts, gets to 80%, then crashes with "Processing Error."Split your data by year. Import 2022 transactions first, let it complete fully. Then import 2023, etc. This prevents server timeouts and makes debugging easier if something breaks.For mega-portfolios (50k+ transactions), honestly consider their $3,499 VIP service. They process large accounts on dedicated infrastructure that doesn't timeout.

My cross-chain bridge transactions are creating double-counting issues

TokenTax sees ETH leaving Ethereum mainnet and WETH appearing on Polygon as two separate taxable events. This doubles your transaction count and can create phantom gains.Mark all bridge transactions as "Internal Transfers." Go to each bridge send/receive pair, change both to "Transfer" type. This treats them as movement between your own wallets (non-taxable).Be careful with bridge timing. If you bridged ETH at $2,000 and it arrived as WETH when ETH was $2,100, there might be a genuine $100 gain from price movement during the bridge.

TokenTax support is taking forever and tax deadline is approaching

Their support is genuinely good but overwhelmed during tax season. Here's how to get faster help: 1. Use chat instead of email (faster queue) 2. Be specific: "Binance API import failing with error X" not "imports broken" 3. Include screenshots of error messages 4. If urgent, mention your plan type (VIP gets priority) If you're truly stuck and deadline is near, export whatever data you have as CSV and file an extension. Fix TokenTax issues after April deadline pressure is gone.

TokenTax Technical Reference Guide

Critical System Limitations

Performance Thresholds

Breaking Point: 25,000+ transactions cause server timeouts at 80% completion
API Rate Limits: Hit during tax season when multiple users import simultaneously
Processing Capacity: VIP accounts ($3,499) get dedicated infrastructure that doesn't timeout

Seasonal Failure Patterns

January: System works reliably
February: Minor sync delays appear
March 1st+: Infrastructure collapse - API timeouts, CSV errors, pricing oracle failures
Support Queue: 3-day response times during tax season

Configuration Requirements

Binance API Setup

Required Settings:
- "Enable Reading" ✓
- "Enable Trading" ✗ (causes connection blocks)
- Wait 5 minutes after key creation (Binance lag)
- Optimal connection time: 3am (lower traffic)

CSV Import Format

Critical: Use exact TokenTax Universal Template
No modifications: Headers, columns, date formats must match exactly
Export Format: Use "Generic CSV" from other platforms, not native formats

Production Failure Modes

API Disconnection Root Causes

Binance: Random permission resets during security updates
Rate Limits: Triggered by concurrent user imports during tax season
MetaMask Scanner: Skips transactions during high gas periods

DeFi Recognition Accuracy

60%: Correctly handled protocols
30%: Require manual intervention
10%: Need external calculation

Reliable Recognition:

Uniswap V2 (popular pairs only)
Compound lending/borrowing
Basic staking on major protocols
Ethereum mainnet (when gas allows tagging)

Fails Consistently:

Layer 2 protocols (Polygon, Arbitrum, Optimism)
Uniswap V3 concentrated liquidity
Cross-chain bridges (especially smaller ones)
Yield aggregators (Yearn, Convex, Beefy)
NFT trades on newer marketplaces

Pricing Oracle Failures

Symptom: LP tokens valued at $47,000 instead of $47
Frequency: Common during March processing
Impact: False $50k tax liability on $5k actual gains

Implementation Solutions

Emergency Workarounds

# API Timeout Recovery
1. Disconnect all APIs
2. Wait 24 hours
3. Reconnect one at a time with 10-minute gaps
4. Alternative: Manual CSV export bypasses rate limits

Data Integrity Fixes

Margin Trading Corrections:
- Delete "Borrow USDT" entries
- Delete "Repay USDT" entries
- Keep only actual trade entries
- Fixes 90% of margin calculation errors

NFT Cost Basis Calculation

Actual Cost Basis = Mint Cost + Gas Fees + Marketplace Fees + Creator Royalties
Common Error: TokenTax excludes fees, creating false gains

Resource Requirements

Time Investment by Complexity

Simple Portfolio (2-3 exchanges, <500 transactions): 2-4 hours setup
DeFi Active (multiple protocols): 10-15 hours for manual corrections
High Volume (15,000+ transactions): 40+ hours without automation
VIP Service: Saves 40+ hours for complex portfolios

Expertise Requirements

Basic Use: No special knowledge needed
DeFi Corrections: Understanding of protocol mechanics required
Margin Trading Fixes: Advanced knowledge of position calculation
Cross-chain Issues: Understanding of bridge mechanics essential

Decision Framework

TokenTax Worth Using When:

15,000+ transactions (automation value exceeds manual effort)
Multiple margin trading accounts
Significant DeFi yield farming
Cross-chain arbitrage activity
Business crypto operations
Time worth >$50/hour

Switch to Alternatives When:

<500 transactions total
Only major exchange trading
UI/UX priority over features
Budget constraints (<$199 threshold)
Need specific unsupported features

Critical Warnings

Tax Season Preparation

Deadline: Complete calculations by January 15th
Backup Strategy: Export all data to CSV before March
Failure Recovery: File extension if system breaks during deadline

Aggressive Tax Positions

Staking Treatment: "No taxation upon receipt" setting is aggressive
Audit Risk: Be prepared to defend with precedent cases
CPA Consultation: Required for complex positions

Data Loss Prevention

Server Timeouts: Split imports by year for large portfolios
Backup Exports: Save CSV copies before making corrections
Version Control: Track manual edits in separate files
