Don't Forget to Include Your Starbucks Run on Your Tax Return

The biggest barrier to Bitcoin and crypto becoming everyday payment methods is one that hardly ever gets talked about — taxes. After all, who wants to discuss them?

Bitcoin has always excelled at large transfers. It can fully settle a $1 million transaction in about 10 minutes with tiny fees — something traditional banks still can’t reliably do. But try buying a $10 coffee when there’s a line of impatient caffeine deficient customers behind you? The base layer is simply too slow for real-time retail.

Lightning to the Rescue

That’s where the Lightning Network comes in — a Layer 2 solution built on top of Bitcoin. It uses real BTC (not a separate token) for near-instant, low-cost transactions, making small and micro-payments practical.

Lightning adoption has been slower than many hoped, partly because traditional payment processors risked losing their fee revenue if they integrated it. But that’s changing.

Square (co-founded by longtime Bitcoin advocate and former Twitter CEO Jack Dorsey) has begun rolling out Lightning support to its merchants, with full availability targeted for 2026. Square already powers payments for millions of small businesses worldwide. This move could be a game-changer, pressuring other providers to follow suit. When Jack backs something in Bitcoin, he tends to deliver.

The Real Hurdle Isn’t Technical — It’s Tax

While the technical side is gradually sorting itself out, the much bigger adoption blocker remains: tax red tape.

Bitcoin isn’t broken. The tax rules are.

If you had to log a capital gains entry every time you grabbed a coffee, you’d immediately know the system is flawed. Yet that’s exactly what using Bitcoin (or most crypto) for payments requires today.

How It Currently Works

Bitcoin is treated as property or a commodity. Every time you spend it, it counts as a taxable “disposal,” triggering capital gains tax on any gain since you bought it.

The math is straightforward — and painful for daily use. Suppose you bought Bitcoin at $10,000 per BTC and it’s now worth $100,000. No tax while you hold.

But spend $10 worth on a triple-shot caramel latte? You’ve just “sold” a fraction that originally cost you ~$1. That creates a $9 taxable capital gain. Even tiny gains must be tracked, calculated, and reported. The administrative headache alone stops most people from using crypto at the till.

UK vs US: Different Pain, Same Problem

In the UK, you have an annual Capital Gains Tax allowance of £3,000. Anything below that is tax-free — but it’s a total yearly limit, not per transaction. You still need detailed records of every spend to prove where you stand.

In the US, the burden is heavier with no equivalent broad allowance for these micro-transactions.

The De Minimis Proposal — Progress, But Not Enough

The US is trying to fix this with a De Minimis exemption (Latin for “concerning minimal things”). The goal: make small crypto payments tax-free with no record-keeping required — exactly like paying with fiat.

Early drafts of crypto legislation floated a $200 threshold, but it often applied only to stablecoins. Since stablecoins are pegged to the USD and don’t appreciate, this would exempt basically nothing.

Senator Cynthia Lummis has advocated for a $300 De Minimis exemption that includes Bitcoin (with proposals sometimes including an annual cap) and is the most useful proposal currently by far for Bitcoin. The final number could land between $200–$600, but if it excludes assets like Bitcoin, it won’t be meaningfully in everyday spending.

The Real Solution: Treat Bitcoin Like Money

For Bitcoin to achieve widespread adoption as a payment method, we need bolder action: remove capital gains tax on consumer payments entirely (or at least for everyday amounts).

Countries like the UAE, El Salvador, Panama, Hong Kong, Malaysia, and Singapore already offer very favourable or zero tax treatment. Even Switzerland, Germany, and Portugal effectively charge 0% on long-held crypto for non-traders.

When leaders talk about making the US the “crypto capital of the world,” this is the kind of decisive thinking required. Taxing every coffee purchase as a capital event isn’t innovation-friendly — it’s a barrier.

Conclusion

Lightning is ready. Merchants are coming online. The missing piece is fixing the tax rules so people can actually use Bitcoin without turning every transaction into an accounting nightmare.
