ASC 842 vs IFRS 16: Key Differences for US Companies with International Leases

If your company is US-based but leases office space, warehouses, or equipment overseas, you're likely dealing with two lease accounting standards at once: ASC 842 (US GAAP) and IFRS 16 (the international standard). They share the same origin story — both were introduced to bring lease obligations onto the balance sheet — but they diverge in ways that matter for how you classify leases, calculate liabilities, and choose software.

The core difference: lease classification

This is where the two standards genuinely part ways.

ASC 842 keeps the old two-bucket approach for lessees: a lease is classified as either an operating lease or a finance lease, based on criteria like whether ownership transfers, whether there's a bargain purchase option, or whether the lease term covers most of the asset's useful life. Both types go on the balance sheet, but they're presented and expensed differently on the income statement.

IFRS 16 did away with that distinction entirely for lessees. Under IFRS 16, nearly all leases are treated the same way — recognized as a right-of-use asset and a lease liability, full stop. There's no separate "operating lease" category to track.

Why it matters for your tech stack: if your company reports under both standards — say, US GAAP for your consolidated financials and IFRS 16 for a foreign subsidiary — your software needs to run true dual-standard calculations in parallel, not just relabel one output as the other. Several tools in this directory (LeaseQuery, EZLease, Cradle, Nakisa, Trullion, and others) explicitly support parallel ASC 842/IFRS 16 reporting; some smaller or US-only tools, like iLeasePro, intentionally don't.

Discount rates: a quieter but real difference

Both standards let you use the rate implicit in the lease when it's determinable, and your incremental borrowing rate when it's not. But the practical guidance differs slightly — IFRS 16 is a bit more prescriptive about how to determine that rate for a specific asset and lease term, while ASC 842 gives private companies a practical expedient to use a risk-free rate instead. If your leases span jurisdictions, this is a detail worth confirming with your auditor rather than assuming your software handles it identically across standards.

What's actually the same

It's easy to over-focus on the differences. In practice, most of the day-to-day mechanics line up:

• Both require recognizing a right-of-use asset and lease liability at commencement
• Both require reassessment when a lease is modified
• Both exempt short-term leases (12 months or less), and IFRS 16 additionally exempts low-value assets
• Both require expanded footnote disclosures compared to the old standards they replaced

If your team already has ASC 842 processes in place, you're not starting from zero to add IFRS 16 — you're extending existing muscle memory, not building a new one.

What this means for choosing software

If your lease portfolio is 100% domestic, most tools in this directory will serve you fine on the accounting side — the differentiation matters more once IFRS 16 enters the picture. A few practical questions worth asking any vendor:

• Does it run ASC 842 and IFRS 16 calculations in parallel on the same lease, or does it require maintaining two separate lease records?
• Does it support multi-currency and foreign exchange translation for non-USD leases?
• Does the vendor's own team have IFRS 16 expertise, or is it primarily a US GAAP shop that added IFRS support later?

You can browse tools filtered specifically by Compliance Standards — including ASC 842, IFRS 16, and GASB 87/96 — to narrow down which platforms actually support the combination your portfolio needs, rather than reading through 23 individual product pages to find out.

A note on GASB, if it applies to you

If any part of your organization is a government entity or receives government funding, you may also be dealing with GASB 87 (and its subscription-based IT arrangement counterpart, GASB 96) — a third standard with its own quirks. Several tools in this directory support all three standards in parallel, which is worth checking if your reporting requirements span public and private sector rules.
