Good to know
Polynomial specifics.
- Your Polynomial address is the same 0x address you use on Ethereum and other EVM networks, but Polynomial keeps its own history: add the address for Polynomial to bring that history in.
- Polynomial uses ETH for gas. Each fee is spent ETH, so HashBooks records the fee and, where your country treats spending crypto as a disposal, its gain or loss.
Worked example
How the tax adds up.
A typical move onto Polynomial, as your tax office would treat it. These are example figures, not yours; HashBooks uses your own history for those.
Illustrative · United States
| Bridge 1 ETH from Ethereum (cost $2,000) | Not a sale |
|---|---|
| Swap the ETH for tokens worth | $2,600 |
| Cost basis carried over the bridge | −$2,000 |
| Gain on the swap | $600 |
| Gas paid in ETH, added to cost | −$4 |
| Reported gain | $596 |
The bridge keeps your original cost; the swap is the taxable event. The full example in the help centre.
Illustrative · United Kingdom
| Bridge 1 ETH (pool cost £1,600) | Not a disposal |
|---|---|
| Swap the ETH for tokens worth | £2,100 |
| Allowable cost from the pool | −£1,600 |
| Gas on the swap | −£3 |
| Gain | £497 |
Counts towards your £3,000 annual exempt amount. The full example in the help centre.
Illustrative · India
| Bridge 1 ETH (cost ₹1,70,000) | Not a transfer |
|---|---|
| Swap the ETH for tokens worth | ₹2,20,000 |
| Cost of acquisition | −₹1,70,000 |
| Gain (gas isn’t deductible) | ₹50,000 |
| Tax at 30% plus 4% cess | ₹15,600 |
On-chain swaps have no exchange to deduct TDS, so check whether you need to pay it. The full example in the help centre.

Questions
Polynomial, answered.
Is bridging to Polynomial taxable?
Moving your own crypto to Polynomial through a bridge is generally not a sale, because you still own it. Watch for bridges that swap the token on the way: receiving a different asset can be a disposal. HashBooks matches the two sides when both addresses are connected.
Are Polynomial gas fees tax deductible?
It depends on your country. In the US and UK a fee paid on a trade usually becomes part of its cost or reduces proceeds; in India only the cost of acquisition is deductible. HashBooks applies the rule for the country you file in.
Which HashBooks plan do I need for Polynomial?
Connecting Polynomial and seeing an estimated tax summary is free for up to 100 transactions across 3 connections. Filing reports for your country start on the Starter plan; see pricing.
Can HashBooks move anything from my Polynomial address?
No. A public address shows history but can’t sign anything, and HashBooks never asks for a recovery phrase or private key. It reads; it can’t trade, withdraw or transfer.
