Why this matters in 2025
- Banks are tightening monitoring of crypto-linked inflows and connecting blockchain analytics that map fiat transactions to on-chain movements, raising the bar for transparent proof of funds.
- The tax authority treats crypto as property: gains from sale/exchange are taxable; missing documentation increases the risk of account freezes and assessments.
Core principle: every ruble must have a beginning
- Any ruble amount that lands in an account after converting crypto must have a traceable history: when and where the asset was acquired, how it was held/grew, where and how it was exchanged into fiat. This “explainability” is the key criterion for both banks and the tax authority.
Document checklist by source type
Purchases on exchanges (CEX) or via P2P
- Exchange account statement: trade history, deposits/withdrawals, order IDs.
- Bank statement/payment slip for fiat deposits (if any) and platform fee receipts.
- Screenshot/rate report on the trade date (from the exchange UI or a quote aggregator).
- For P2P: order page, chat screenshots, payment confirmations, and the counterparty’s bank receipt for non-cash transfers.
Trading/investing
- Export trade reports (CSV/PDF) with metadata: date/time, pairs, volumes, fees.
- Summary P/L in rubles using the official rate on each trade date (attach your method).
- Logs of fiat in/out that reconcile to bank statements.
Mining
- Hardware invoices/receipts, hosting/colocation contracts, power supply contract, meter readings and cost calculations.
- Pool statements and on-chain history of the reward wallet.
- If activity is regular—sole proprietor/self-employed status and chosen tax regime.
Service/freelance income in USDT
- Contract/offer letter/email chain with the client, USDT invoice, proof of work delivery.
- On-chain receipt to your address (tx hash) linked to the invoice (ID/amount/date).
- USDT→RUB conversion documents: exchange receipt/P2P offer screenshot/service statement, rate and fee.
How to present the “money chain” to the bank
- Diagram/schematic: Fiat source → crypto purchase (exchange/service) → holding/trading (optional) → crypto-to-ruble off-ramp (platform/service) → bank receipt (with account details).
- Explanatory note: short narrative for each link in the chain, with links/IDs to documents and transactions, plus a final ruble calculation.
Practice: several banks consider crypto-related inflows if a complete package is provided in advance; a missing “start of chain” often leads to rejection or blocking.
Tax bookkeeping and reporting
- Individual return: report crypto gains annually; standard timelines apply (file by April 30, pay by July 15); use the official ruble rate on the operation date.
- Expenses: reduce gains by documented costs (fees, acquisition, etc.); within the year, losses can offset gains from other crypto operations where allowed.
- Attachments: bank and exchange statements, fee receipts, payment order screenshots, off-ramp documents, plus your calculation method and transaction chain.
Common compliance triggers and how to avoid them
- “Triangular” payouts: rubles arrive from someone other than the buyer—risk of chargebacks/blocks; avoid, verify names, and use escrow.
- Off-platform deals and site clones: always verify domains/SSL and keep chat/payment logs and screenshots.
- Large atypical sums without history: split inflows, inform the bank in advance, and provide the full documentation pack proactively.
Organizing your evidence archive
- Store in cloud with backup: folder structure by year/platform/counterparty; file names with date and deal ID.
- Export monthly: exchanges/wallets may limit historical depth—don’t wait until year-end.
- Keep a “rates sheet” for key operation dates (screenshots/CSV).
What to expect by late 2025
- Broad bank connectivity to blockchain analytics will increase inquiry likelihood; prebuilt “money chains” and document kits will speed reviews.
FAQ
- Do I need to prove every ruble deposit? Banks selectively review atypical/large flows; a prepared “every ruble has a beginning” package lowers risks.
- Can I skip exchange statements? Not advisable: without purchase/sale history, both bank and tax authority will struggle to verify. Export reports early and often.
- What if part of my history on an old exchange is gone? Reconstruct with email/ screenshots, bank statements, on-chain records, and third-party rate archives; add an explanatory note.
- Will expenses (fees, equipment) be deductible? Yes, if properly documented and consistent with your tax calculation method.
