How does Montana's new 1099-DA reporting divergence affect crypto investors?

Montana became the first state to issue guidance specifying it would not rely on the federal/state combined 1099-DA filing program. That means cryptocurrency exchanges and brokers must create separate state-specific electronic 1099-DA files and submit them directly to the Montana Department of Revenue, rather than letting the IRS forward the data on Montana's behalf. Montana has also indicated it may not honor the IRS's transitional relief from penalties for early 1099-DA reporting periods. The practical implication for Montana crypto investors is that any reporting mismatch between your federal return, your state return, and the data brokers transmit to Montana DOR can trigger separate state-level scrutiny. Chainwise CPA tracks Montana-specific reporting requirements alongside federal compliance to keep both sides clean.

Does Montana tax cryptocurrency gains at the same rate as ordinary income?

No — Montana applies preferential rates to long-term capital gains (assets held more than one year), separate from ordinary income brackets. For tax year 2025, ordinary income is taxed at 4.7% or 5.9% depending on bracket, while long-term capital gains are taxed at 3.0% or 4.1% using thresholds tied to the ordinary brackets. For Montana crypto holders, this means holding digital assets more than a year produces meaningfully lower state tax than short-term trading. Strategic timing of sales around the one-year holding period can produce real Montana state savings on top of the federal long-term capital gains advantage.

How do HB 337's rate changes affect Montana crypto tax planning?

Montana's HB 337, signed into law in 2025, reduces individual income tax rates beginning in tax year 2026. The top ordinary income rate drops from 5.9% to 5.65% in 2026, then to 5.4% in 2027. The lower bracket also widens substantially. Long-term capital gains rates (3.0% and 4.1%) remain unchanged, but their thresholds adjust to track the wider ordinary brackets. For Montana crypto investors planning large realizations, when you sell can matter as much as how much. Chainwise CPA helps Montanans time crypto sales around the rate schedule to capture the lower 2026 and 2027 rates where appropriate.

How is cryptocurrency mining taxed for Montana residents?

Federal IRS rules govern crypto mining taxation, and Montana follows federal treatment for the underlying income. Mining rewards are generally taxed as ordinary income at fair market value on the date received. Whether your activity rises to the level of a trade or business is a fact-specific determination that affects deductions: trade-or-business miners may deduct equipment depreciation, electricity, and other ordinary business expenses but become subject to federal self-employment tax. Montana has hosted significant mining operations driven by cheap hydropower and cool climate. Chainwise CPA helps Montana miners structure their activity correctly and capture both federal deductions and Montana's lower long-term capital gains rate when mined coins are eventually sold after a holding period.

What is Form 1099-DA and how is Montana's version different?

Form 1099-DA is the IRS reporting form crypto exchanges and brokers issue for digital asset transactions, with broader rollout taking effect across recent tax years. Most states accept federal 1099-DA data through the IRS's combined federal/state filing program. Montana, however, has issued guidance requiring brokers to file separately to the Montana Department of Revenue — making it the first state to break from the federal program. This means Montana investors should expect their state return reconciliation to involve state-specific data flows that don't always match what shows up on their federal IRS account transcripts. Chainwise CPA tracks both data streams to prevent mismatch-driven notices.

Can a CPA based in Virginia prepare my Montana tax return?

Yes. Certified Public Accountants licensed in any U.S. state can prepare federal returns and out-of-state state returns, including Montana's Form 2. Chainwise CPA serves Montana clients remotely with secure document handling, encrypted client portals, and video meetings. Our credentialed team brings deep crypto expertise, current tracking of Montana's 1099-DA divergence, and working knowledge of HB 337's rate transitions through 2027 — depth that few in-state generalist CPAs currently offer.

I was at the end of my rope trying to decipher the never ending new rules and regulations of the IRS, as it pertains to crypto. I thought I was doing a good job keeping everything in order with my exchanges, transfers and swaps, until I received my 1099 - DA's, which were highly inaccurate. I knew my problems would only get worse if I didn't take a more professional approach in addressing them, so I needed to hire a crypto and tax expert.

As I researched this topic, one crypto advisory group clearly stood out amongst their competition, and that was Polygon Advisory Group. Before I could sign up with them, I had to have brief meeting with them to see if my needs and their talents would align. After our 15 minute intro meeting, I was more than convinced they had the skillset, and desire, to unravel my crypto challenges.

I have to commend Daniel B. and his extraordinary talent to analyze my crypto reports and then provide reconciliation for all of my accounts. He was also intuitive to recognize many gaps in my information and then investigate deeper to connect all of the data points. There is no possible way I could have performed such a feat by myself. When all was finished, Daniel went back in my previous tax returns and even recommended that I file amendments for the last 5 years, and that ended up saving me a lot of money (excess $10K) due to me incorrectly reporting my crypto income.

Closing: So many companies are only willing to document the numbers that you provide them and then quickly close your file. Polygon Advisory Group digs in deep and investigates the incomplete files/data and helps you bring resolve to your crypto headaches. I'll use them again next year, as they have my complete trust!

I was new to crypto trading and lacked knowledge about how crypto transactions are taxed and how to report crypto profits and/or capital gains to the IRS. As a new customer, I contacted Polygon Advisory Group services to prepare my tax documents for both all my crypto transactions and for my regular income and other financial investment earnings. Their services were comprehensive and thorough and in compliance with every detailed aspect of my IRS and Virginia tax filing requirements.
