Pricing
One subscription per tax year.
Access is licensed per tax year. A key issued for 2026 opens the 2026 platform; renewing for 2027 adds that year. Each subscription carries its account type, plan, team seats — and which products it covers.

How activation works
- You subscribe and receive an access key — e.g. ATP-FIRM-2026-4K7Q.
- You activate the key on this site; your private workspace opens for that tax year.
- When the next year opens, renew with a new key and it is added to the same account.
What happens if a year is not renewed
Returns for years outside your subscription open read-only — nothing is deleted, and your history stays intact. Add the year with a renewal key to resume preparing and filing for it.
