Koinly Promo Codes: Active Discounts for December 2025

Crypto tax reporting can be costly for active traders, but using a valid promo code can significantly reduce the price of your annual tax report. As of December 2, 2025, multiple Koinly codes remain active, offering discounts ranging from 10% to 40% off paid plans. This guide outlines the most reliable codes currently working, categorized by discount value and specific plan requirements, to help you secure the best possible price.

Top-Tier Percentage Discounts (30-40% Off)

These codes offer the highest potential savings and should be your first choice at checkout. They typically apply to all paid tiers, including Newbie, Hodler, and Trader plans.

BF24

This is currently the strongest general-purpose code available. It provides a massive 40% discount on all paid plans. While originally introduced as a seasonal promotion, it remains active as of December 2, 2025. If you are purchasing a full-price tax plan, this code offers the deepest price cut available.

Code: BF24

POLY30

This code offers a flat 30% off sitewide. It is a reliable alternative if the 40% code does not apply to your specific account or region. Current data indicates this code is valid through December 2, 2025, with no specific end-date currently listed.

Code: POLY30

E0F18DD6

Another strong option delivering 30% off all tax plans. This alphanumeric code is frequently updated in community lists and remains verified as working in late 2025. It serves as an excellent backup for substantial savings on standard pricing.

Code: E0F18DD6

Reliable Mid-Range Codes (20-25% Off)

If the top-tier codes have expired or are restricted by region, these codes have a high success rate and are widely reported as active.

PAYM25

This code applies a 25% discount to any order. It acts as a solid “catch-all” coupon when steeper discounts fail. Reports confirm it is active and usable as of December 2, 2025.

Code: PAYM25

NEWTON25

Originally associated with the Newton exchange partnership for the 2025 tax season, this code continues to provide approximately 20% off paid plans. It works for both new and returning customers. While it had an initial target date of April 2025, it is still being successfully applied in December 2025.

Code: NEWTON25

2263CBAA

A consistent 20% off code applicable to most plans. This code is frequently highlighted in deal trackers as a “best current” option when major seasonal sales are not active.

Code: 2263CBAA

Evergreen and Partner Discounts

These codes are designed for long-term use and are less likely to expire than seasonal promotions. They are ideal for users who want a dependable discount year after year.

talerbox

This partner code offers 20% off all tax packages. Unlike one-time use codes, this is often described as a “lifetime” or reusable discount that can be applied in subsequent tax years. It remains a stable option for December 2025.

Code: talerbox

SBORG15

A popular code providing 20% off your first tax report or all plans, depending on the account type. It is widely listed as verified and active across multiple coupon directories for the 2025 tax year.

Code: SBORG15

Plan-Specific and Fixed Amount Deals

These codes target specific user tiers or offer dollar-amount savings rather than percentages. These are best used for specific portfolio sizes.

591C0868 (Newbie Plan Only)

Designed specifically for the entry-level “Newbie” tier, this code offers a 30% discount. If you have a low transaction count and are buying the cheapest plan, this code often provides better value than generic 20% coupons.

Code: 591C0868

94D92 ($40 Off)

This code reduces your total by a fixed $40. For expensive, high-volume plans (such as the Trader tier), a percentage discount usually saves more money. However, for mid-tier plans, a flat $40 reduction might outperform a 10-15% discount. Compare the final price against percentage codes before paying.

Code: 94D92

EA0DCD8A

An older but potentially powerful code offering up to 80% off specifically for 2024 premium plans. While availability may be limited, it is worth attempting if you are catching up on previous year taxes.

Code: EA0DCD8A

Fallback Options

If all major codes fail, these lower-tier discounts generally work as a final resort to ensure you do not pay full price.

4A9D6FFC

A reliable code offering 20% off storewide. It is frequently validated and works on most account types.

Code: 4A9D6FFC

AD416FF7

Provides a 10% to 15% discount depending on the specific plan selected. This is a common fallback code confirmed active in December 2025.

Code: AD416FF7

Maximizing Your Savings

To ensure you get the best deal, follow this testing order during checkout. Koinly allows you to preview the discount before payment.

• Test High-Value Codes First: Start with BF24 or POLY30 to see if you qualify for the 30-40% bracket.
• Check Plan Specifics: If you are on the Newbie plan, compare the 30% off from 591C0868 against other offers.
• Calculate Fixed vs. Percentage: If your plan cost is moderate, the $40 discount from 94D92 might result in a lower final price than a 20% code.
• Look for Referrals: If public codes fail, referral links from existing users typically provide $20-$40 in credits, which can be stacked or used as a strong alternative to percentage discounts.

Always verify the final price on the checkout screen before confirming your purchase. As of December 2, 2025, the codes listed above represent the most accurate opportunities to save on your crypto tax reporting.
