revolutax

A Rust CLI tool for calculating taxes on cryptocurrencies traded on Revolut. It reads the account statement CSV file from Revolut and generates a new CSV file summarizing the taxable trades.

This tools can also generate an SRU file that can be uploaded to Swedish Tax Agency (K4-bilagan - Försäljning - Värdepapper m.m.) Although this program is specifically designed for reporting Swedish taxes, it can also be used for general tax reporting purposes in other countries.

Installation

To install Rust, follow the official installation guide available at rustup.rs.

After Rust is installed, clone the repository and build the project:

$ cargo build

Usage

The program reads the transactions of type EXCHANGE and CARD_PAYMENT and generates a new csv file tax.csv. For example:

$ cargo run -- account_statement.csv > tax.csv

Here is an example input CSV file account_statement.csv:

Type,Product,Started Date,Completed Date,Description,Amount,Currency,Fiat amount,Fiat amount (inc. fees),Fee,Base currency,State,Balance
EXCHANGE,Current,2023-01-01 10:00:00,2023-01-01 10:00:00,Exchanged to EOS,100.0000,EOS,600.00,609.15,9.15,SEK,COMPLETED,100.0000
EXCHANGE,Savings,2023-01-01 11:00:00,2023-01-01 11:00:00,Exchanged to EOS,50.0000,EOS,300.00,304.15,4.15,SEK,COMPLETED,50.0000
EXCHANGE,Current,2023-01-02 10:00:00,2023-01-02 10:00:00,Exchanged to SEK,-30.0000,EOS,-400.00,-394.86,5.14,SEK,COMPLETED,70.0000
CARD_PAYMENT,Current,2023-05-06 10:00:00,2023-05-06 10:00:00,Payment to Amazon,-25.0000,EOS,-500.00,-495.75,4.25,SEK,COMPLETED,45.0000

The program generates a tax report tax.csv that looks like this:

Date;Currency;Amount;Income;Cost;Net Income
2023-01-02 10:00:00;EOS;-30;394.86;-182.7450;212.1150
2023-05-06 10:00:00;EOS;-25;495.75;-152.2875;343.4625

This report shows the following information for each transaction:

Date: The date and time when the transaction occurred.
Currency (Valutakod): The currency used in the transaction.
Amount (Antal): The amount of currency used in the transaction.
Income (Försäljningspris): The income generated from the transaction, calculated in the base currency (SEK).
Cost (Omkostnadsbelopp): The cost of the transaction, calculated in the base currency (SEK).
Net Income (Vinst/förlust): The net income generated from the transaction, calculated by subtracting the cost from the income.

Current vs. Savings

The program algorithm takes into account the two types of Product of transactions: Savings and Current. Specifically, when calculating the tax for a trade where you sold cryptocurrency, the program will first try to find the costs for the sold crypto in the Current transactions and deduct them from there. Only when there are not enough available costs to deduct on the Current transactions will the program deduct from the Savings transactions.

Swedish Tax Agency

To generate an SRU file for the Skatteverket, provide the --sru-file flag. This will produce a file with a .sru extension, containing the same capital gain information as the CSV output, and is equivalent to a filled K4-bilagan form. The generated SRU file is formatted according to the Skatteverket's specifications and includes relevant headers such as #BLANKETT and #UPPGIFT.

The --sru-org-num flag should also be provided, followed by the personal/organization number of the taxpayer. This number is included in the #IDENTITET header, which is required by the Skatteverket. For example:

$ cargo run -- \
    --sru-file \
    --sru-org-num 195012310123 \
    --sru-org-name "Svea Specimen" \
    --year-traded 2023 \
    --sum \
    revolut-2023.csv > BLANKETTER.sru

With --sru-file flag, the program generates an SRU file BLANKETTER.sru:

#BLANKETT K4-2022P4
#IDENTITET 195012310123 20230428 222030
#NAMN Svea Specimen
#UPPGIFT 7014 1
#UPPGIFT 3410 55
#UPPGIFT 3411 EOS
#UPPGIFT 3412 891
#UPPGIFT 3413 335
#UPPGIFT 3414 556
#BLANKETTSLUT
#FIL_SLUT

The generated SRU file can be submitted to the Skatteverket electronically, simplifying the tax reporting process for the taxpayer. If the --sru-file flag is not used, the program will produce a CSV file containing the same information.
