NDA & confidentiality before any client data

Every engagement starts with a comprehensive NDA. Encrypted transfer channels, strict access controls, and white-label operation under your firm — we do not contact your clients unless you authorize it.

Built inside real CPA crypto practices

We’ve trained and led crypto accounting divisions at three CPA firms — building playbooks so internal teams could handle multi-software recon, DeFi edge cases, and partner-review packages without depending on ad-hoc offshore workflows.

Firm names withheld under NDA. Discovery calls can include anonymized process walkthroughs.

“We needed someone who would work inside our engagement model — not drop a foreign process on the team. Basislane adapted to our software and standards, and left us with workpapers partners could actually sign off on.”

Engagement model

How an engagement works

Predictable process. Your tools. Your review standards.

  1. Discovery call

    Scope, software stack, volume, jurisdictions, and seasonality. No client data required on the first call.

  2. NDA & secure intake

    Executed NDA, access controls, and encrypted transfer of exports / wallet lists — only after paperwork is in place.

  3. Reconcile & document

    Software recon, on-chain labeling, 1099-DA checks, and workpapers built to your firm’s review style.

  4. Partner package

    Deliverables under your brand for partner review. Optional training so your team can own more next season.

Typical response within 24 hours. Project turnaround usually 3–30 days depending on volume and complexity.

Engagement effort estimator

Illustrative hours and turnaround from transaction volume, processing speed, and scope. Not a quote — discovery calibrates pricing.

Engagement scope
Formula: Hours ≈ (transactions ÷ speed) × complexity × scope multiplier

Scope multiplier = 1.0 for base reconciliation, plus the percentages of each extra service checked. Turnaround assumes ~8 productive hours/day. CPA time saved is an indicative range (≈1.5–2.5× specialist hours), not a guarantee.

Founder

Built by a Chartered Accountant who has stood inside CPA crypto desks

I founded Basislane after watching firms struggle with providers who imposed rigid offshore systems on established practices. The friction cost more than it saved.

My approach is simple: adopt your tools and standards, deliver workpapers partners can defend, and leave optional playbooks so your team grows capacity — not dependency.

Differentiation

Why firms choose Basislane over generic support

Capability Generic offshore / gig help Basislane
Workflow fit Often forces their templates Works inside your crypto tax platforms & firm review process
Confidentiality Varies by vendor NDA before any wallet or export
DeFi / perps depth Shallow labeling common On-chain forensics + partner memos
1099-DA era Manual spreadsheets In-house reconciler + custom tooling
Client relationship Sometimes contacts clients White-label; your brand only by default
FAQ

Frequently asked questions

Every engagement starts with a comprehensive NDA before we receive wallet addresses or exchange exports. Data moves over encrypted channels with strict access controls. We operate under your firm’s brand and do not contact your clients unless you explicitly authorize it.
Typical response time is within 24 hours. Project turnaround usually ranges from about 3 days (small, simple portfolios) to 30 days (large multi-chain DeFi/perps/bridge engagements), depending on volume, data quality, and scope.
Engagements are scoped after discovery based on transaction volume, complexity, software stack, and deliverables. The on-site effort estimator is for planning only. We support project-based packages, seasonal capacity, and ongoing white-label retainers for firms with recurring crypto volume.
Individuals: Koinly, CryptoTaxCalculator (Summ), Awaken.tax, CoinTracking.info, and CoinTracker. Web3 businesses: Integral, Cryptoworth, Summ Business, and Breezing. We adapt to whatever stack your firm already uses rather than requiring a migration.
Yes. We built an in-house 1099-DA Reconciler (Coinbase Form 1099-DA PDF vs Koinly Capital Gains CSV) with 3-stage recon and Excel/PDF workpapers. Explore the tool free online. Complex mismatches and custom firm workflows can be scoped under engagement.
We are US-primary (Form 8949, Schedule D, 1099-DA workflows) and can support UK (HMRC), Canada (CRA), Australia (ATO), and Germany (BZSt) frameworks when scoped in discovery. Multi-jurisdiction work is quoted with clear assumptions.
No. We act as an extension of your crypto tax / crypto accounting workflow: the platforms you already use (Koinly, CTC, Awaken, QBO/Xero for Web3 entities, etc.), your engagement style, and your review checklist. We execute and document around what you already run — we are not a full-service income-tax prep shop.
We prioritize firms that book capacity early. On the discovery call we align on volume windows, SLAs, and whether you need project overflow, a reserved seasonal block, or a year-round retainer for recurring crypto clients.

Ready to extend your firm’s crypto capacity?

Book a 20–30 minute discovery call with Chirag Kotadiya, CA. Bring your software stack and approximate volume — we’ll map fit, turnaround, and a clear next step. NDA before any client data.

Privacy notice

When you submit the discovery form, we use your name, firm, email, and request details solely to respond to your inquiry (including via email or calendar tools you opt into). We do not sell personal information. Client portfolio and wallet data are never collected through this website form and are only accepted after an executed NDA under separate engagement terms.
