Bitcoin mining isn’t just about hardware and hash power — it’s also an accounting and tax strategy opportunity. By strategically managing how electricity is tracked, allocated, and capitalized into the cost basis of mined Bitcoin, miners can create legitimate losses and deductions that offset other business income. This guide brings together practical guidance on electricity cost tracking, capitalization, specific identification accounting, tax loss harvesting, and structuring around software businesses funded by mining-related activities.
Capitalizing Electricity in Bitcoin Mining
Electricity used in Bitcoin mining can be either expensed or capitalized. The default is to deduct it as an operating expense, but you can capitalize it into the basis of the Bitcoin mined, provided you use a consistent and well-documented method. You may choose to capitalize only a portion of electricity costs (e.g., 60% for production rigs), while expensing the rest (e.g., admin usage, test rigs). This split is valid and beneficial when done consistently with clear supporting logs.
When Is Bitcoin “Earned”?
Bitcoin is considered earned — and thus taxable — at the moment you gain “dominion and control” over it. For solo miners, this is when the block reward is credited to your wallet. For pool miners, it’s when your payout is distributed. At that time, the fair market value (FMV) in USD becomes the amount of income recognized, and that same FMV becomes your cost basis unless you’ve capitalized expenses into it.
Specific Identification and Tax Loss Harvesting
To optimize gains or harvest losses, miners should use specific identification accounting. This means you must track exactly which BTC lots are being sold, their original basis (including any capitalized costs), and their acquisition dates. Without this, you’re defaulted to FIFO (First-In, First-Out), which may reduce your flexibility. Specific ID lets you sell high-basis BTC for losses while keeping low-basis BTC for gains.
Importantly, as of 2025, the wash sale rule does not apply to crypto. This allows you to sell BTC at a loss, recognize that loss, and repurchase the BTC immediately without disallowing the deduction. This creates a unique tax planning opportunity for reinvestment or offsetting other gains.
Tracking Electricity in Google Sheets
Electricity costs can be tracked manually or semi-automatically using Google Sheets. Input rig wattage, runtime, and cost per kWh to calculate total electricity usage and allocate it per BTC earned. You can also integrate mining pool data and use a blend of submetering and utility bill breakdowns to track usage more precisely. Green Button data from utilities or smart meters like Shelly EM or Emporia Vue can feed data into CSVs that sync with Google Sheets.
Integration from Utility and Submeter Data
Power companies may allow CSV downloads or access to Green Button standardized energy data, while smart submeters provide kWh data per circuit or device. These data sources can be merged into a central tracking system using CSVs or even MQTT/REST APIs if more automation is desired. Tools like Node-RED, Google Apps Script, and Zapier help with automating this process to ensure rig-by-rig electricity tracking aligns with payout intervals.
Crypto Fees, Basis, and Cost Management
Fees paid during BTC transactions — such as mining pool fees, gas fees, and transfer costs — should be added to the basis of the asset if they’re related to acquisition or sale. If you’re transferring BTC to another wallet, those fees are not added to basis, but if you’re selling, trading, or earning it via mining, relevant fees increase the cost basis, reducing potential capital gains. Consistency is key.
When mining Bitcoin, you must include the FMV at the moment of receipt as income. Capitalizing electricity into the basis defers that portion of the income, helping balance income recognition with actual operational cost.
Tax Shield and Strategic Loss Harvesting for SaaS Offsets
A strategic benefit of combining BTC mining with other businesses, like SaaS, is the ability to use mined BTC losses to offset profits from other ventures. For example, if you mine Bitcoin and recognize a loss upon sale (after capitalizing electricity), you may be able to use that capital loss to offset income from a profitable business such as DocupletionForms.com.
Here’s how it works: after mining and recognizing taxable income based on FMV, if the value of BTC drops and you sell it, you can harvest the loss. Then, you can repurchase BTC immediately (no wash sale restriction), and even borrow against it using platforms or private agreements. This borrowed capital can fund development and marketing of your SaaS while the loss offsets your taxable profit.
Structuring this properly means pairing strong recordkeeping with legal separation between entities (e.g., holding BTC in a trust or LLC and operating SaaS from another). As long as you avoid constructive receipt of borrowed BTC, and interest paid on the borrowed amount is reasonable, you maintain clear tax separation while gaining liquidity and shielding income using mined asset losses. This approach combines crypto mining, asset-based lending, and SaaS entrepreneurship into one tightly controlled tax-optimized strategy.
When the initial income of the FMV of bitcoin mined is earned, when are taxes on it due?
When you mine Bitcoin (or any other cryptocurrency), the IRS treats the fair market value (FMV) of the coins at the time they are mined as taxable ordinary income. Here’s a breakdown of when and how taxes are due on mined Bitcoin:
1. Taxation at the Time of Mining
-
Income Recognition: The FMV of the Bitcoin on the day it is mined is considered earned income.
-
Taxable Event: This is a taxable event, even if you do not sell the coins.
-
Type of Income:
-
If you’re mining as a hobby, it’s reported as miscellaneous income (no deductions).
-
If you’re mining as a business or self-employed activity, it is reported as business income on Schedule C and is also subject to self-employment tax (15.3%).
-
2. When Are Taxes Due?
-
Estimated Quarterly Tax Payments: If you’re self-employed or operating a mining business, you are generally required to make quarterly estimated tax payments to the IRS (and your state, if applicable).
-
Due Dates: April 15, June 15, September 15, and January 15.
-
-
Annual Filing: You report the income and pay any balance due on your annual tax return (Form 1040, Schedule C for business income).
3. Example
Suppose you mine 0.1 BTC on June 1, 2025, and the FMV on that date is $65,000/BTC:
-
Income reported: $6,500.
-
If self-employed: Subject to ordinary income tax plus self-employment tax.
-
Report Date: Include this amount on your Q2 estimated taxes due June 15 or file and pay with your annual return.
4. Later Capital Gains
-
When you sell the mined BTC later:
-
The basis is the FMV on the mining date.
-
You pay capital gains tax (short- or long-term) based on how long you held the coins before selling or exchanging them.
-
5. Recordkeeping Tip
Keep detailed records of:
-
Date and time of mining.
-
FMV of Bitcoin at that time.
-
Wallet addresses, confirmations, and transaction IDs.
-
Any associated mining expenses (for deduction if you’re operating a business).
If it is just mined as a business by a business entity then it does not also include self-employed tax?
When Bitcoin is mined by a business entity, self-employment tax does not apply directly to the entity itself. Here’s a detailed breakdown depending on the type of business structure you’re using:
1. If the Mining Is Done by a Business Entity (Not a Sole Proprietorship)
a. Corporation (C-Corp or S-Corp)
-
The corporation reports the FMV of the mined Bitcoin as business income.
-
It pays corporate income tax (for a C-Corp) or passes the income through to shareholders (for an S-Corp).
-
Self-employment tax does NOT apply to the entity or its income.
-
However, if the owner draws a salary, that salary is subject to FICA taxes (Social Security and Medicare), which is similar to SE tax but handled through payroll.
-
Dividends (C-Corp) or K-1 distributions (S-Corp) may have different tax treatments.
b. LLC Taxed as a Corporation
-
Same treatment as above, depending on whether the LLC elects C-Corp or S-Corp taxation.
2. If the Mining Is Done by a Sole Proprietor or Single-Member LLC (Disregarded Entity)
-
The FMV of the mined Bitcoin is treated as personal business income.
-
It is reported on Schedule C of your personal tax return.
-
Subject to ordinary income tax plus self-employment tax (15.3%).
3. If the Mining Is Done by a Partnership or Multi-Member LLC (Default Partnership Taxation)
-
Each partner is allocated their share of mining income via Schedule K-1.
-
The partners are generally responsible for self-employment tax on their portion, unless they’re passive partners.
Summary Table
| Entity Type | Self-Employment Tax? | Notes |
|---|---|---|
| Sole Proprietor / Single-Member LLC | Yes | Treated as personal income |
| Partnership / Multi-Member LLC | Yes (usually) | K-1 income is SE income |
| S-Corp | No (entity level) | Owner’s salary = FICA; distributions = not SE taxed |
| C-Corp | No (entity level) | Entity pays corporate tax; dividends may be taxed again |
| LLC Taxed as Corp | Follows corp rules | Based on election made with IRS |
If you’re running a mining operation under an entity like a C-Corp or an S-Corp, it’s a great way to avoid self-employment tax on all profits, though owner-employees still pay FICA on reasonable compensation.

The taxation rate on mined Bitcoin depends on your business structure and how the income is categorized. Below is a detailed breakdown of how it’s taxed under various structures and scenarios:
1. If Mining as a Sole Proprietor or Single-Member LLC (Default Disregarded Entity)
-
Ordinary Income Tax Rate: Based on your personal income bracket (2025 rates):
-
10% to 37% federal income tax.
-
-
Self-Employment Tax: 15.3% on net income (12.4% Social Security + 2.9% Medicare).
-
Total Effective Rate: Can be ~25% to over 50%, depending on your total income and deductions.
-
State Tax: Add your state income tax (e.g., 1–13.3% in CA).
Example
If you mine $50,000 in BTC profit:
-
$50,000 taxed as income (say 24% bracket).
-
$7,650 in SE tax (15.3%).
-
Possibly ~$12,000 in federal income tax.
-
Plus state income tax.
2. If Mining Through a C-Corporation
-
Flat Corporate Tax Rate: 21% on net profits.
-
No Self-Employment Tax at the entity level.
-
Double Taxation Warning:
-
If profits are paid out as dividends, those are taxed again at the shareholder level (15% or 20%, plus 3.8% NIIT if applicable).
-
But if reinvested or used for business expenses, you can defer or eliminate second layer.
-
3. If Mining Through an S-Corporation
-
Pass-Through Entity: Income flows to shareholders’ personal returns via Schedule K-1.
-
Salary Portion: Subject to FICA (same 15.3%, but split between employer and employee).
-
Distributions (dividends): Not subject to self-employment or FICA tax.
-
Income Tax Rate: Based on your individual bracket (10% to 37%).
Tax Strategy
Pay yourself a reasonable salary, then take remaining profits as distributions to reduce employment taxes.
4. If Mining Through a Partnership or Multi-Member LLC
-
Pass-Through Taxation: Profits passed to partners via K-1.
-
Self-Employment Tax: Partners pay SE tax unless they’re passive partners.
-
Income Tax Rate: Based on each partner’s bracket (10–37%).
Other Considerations
Depreciation and Deductions
-
You can deduct mining equipment, electricity, rent, software, etc.
-
Section 179 and bonus depreciation may allow full write-offs of mining rigs in the first year.
State Taxes
-
Each state has its own tax rate and rules.
-
Texas: No state income tax.
-
California: Up to 13.3%.
