Pre-tax vs. post-tax investing
The wealthy are very good at investing before tax is applied. After-tax investing means you earn income, pay tax, then invest what's left. Pre-tax investing means you use a legal deduction, retirement account, or business asset purchase to get capital working before the IRS takes its full cut.
Post-tax | the spot buyer
Buy Bitcoin with what's left
- Income you earn
- $15,873
- Paid to the IRS first (37%)
- -$5,873
- Left to invest
- $10,000 of Bitcoin
You pay full tax first, then buy the asset with the remainder.
Pre-tax | the miner buyer
Put capital to work before tax
- Income redirected into miners
- $15,873
- Deducted this year (bonus depreciation)
- -$15,873 taxable
- You keep
- Hardware + the BTC it mines
You buy productive equipment with pre-tax dollars, deduct it, and produce Bitcoin over time.
Roughly $10,000 out of pocket either way. One buys static Bitcoin. The other buys a machine that makes Bitcoin, with the IRS covering about a third.
Bitcoin mining tax calculator FAQ
Common questions about bonus depreciation, mining equipment, and federal income tax estimates.
What is the Bitcoin mining tax calculator?+
A free tool that estimates your federal income tax, then shows how buying Bitcoin mining equipment could lower it through 100% bonus depreciation. Enter your filing status, taxable income, and how much you'd invest in miners to see your estimated tax savings and the net, after-tax cost of the hardware.
How do Bitcoin miners reduce your taxes?+
Bitcoin miners are business equipment. When you place them in service in an active mining business, the IRS lets you deduct the full purchase price in year one through bonus depreciation. That deduction lowers your taxable income, which lowers the federal tax you owe.
What is bonus depreciation?+
A tax provision that lets a business deduct 100% of the cost of qualifying equipment in the year it's placed in service, instead of spreading it over several years. It was restored to 100% permanently for property placed in service after January 19, 2025.
How much can I save in taxes by buying Bitcoin miners?+
Your savings equal your marginal tax rate times the amount you invest in equipment. For example, a high earner in the 37% bracket who places $85,000 of miners in service could reduce their federal tax bill by roughly $31,450. Use the calculator to estimate your own number.
What's the difference between pre-tax and post-tax investing?+
Post-tax investing means you earn income, pay tax on it, then invest what's left. Pre-tax investing means you use a legal deduction, like a retirement account or a business equipment purchase, to put capital to work before the IRS takes its full cut. Buying deductible mining equipment is a form of pre-tax investing.
Do I qualify for the Bitcoin miner write-off?+
To deduct the equipment against your other income, the IRS generally requires that you materially participate in an active mining business and that the machines are placed in service (installed and running) during the tax year you claim the deduction. Whether you qualify depends on your specific situation, so confirm with a CPA.
Can I deduct 100% of a Bitcoin miner in the first year?+
Yes. Qualifying mining equipment placed in service after January 19, 2025 is eligible for 100% bonus depreciation, meaning the full cost can be deducted in year one, subject to material participation and other requirements.
Does this calculator include state taxes?+
No. It estimates federal income tax only, using 2025 federal brackets and the standard deduction. It does not include state income tax, self-employment tax, FICA, AMT, or phase-outs, so your actual results will vary.
Is this tax advice?+
No. This calculator is for education only and provides estimates, not tax advice. Confirm any strategy with a qualified tax professional before acting.
