Tax forms by account type. Every form, every quarter, every year.

Forty-five account types across five natures obligate a custodian, trustee, plan recordkeeper or deposit institution to a specific set of federal and state information returns, withholding returns, deposits and statements. This is that set, stated as designed, with the filer role, cadence, deadlines and transport for each form.

Three rules

Records before forms

Every box is derived from ledger facts and registries. No form is typed; corrections are new versions referencing the original.

Filer role is explicit

The platform files where the institution is the filer and prepares data where someone else files — the plan sponsor’s 5500, the employer’s W-2 and 1095.

Quarterly is real

945 deposit schedules, 990-T estimated payments and state withholding returns are scheduled obligations with evidence.

Status. Tax-form coverage is a product specification. The legacy platform produced Forms 5498 and 1099-R; nothing else on this page is generally available today, and availability for any institution depends on that institution’s own authorities, enrollments, contracts and policies. See product status.

Frequently asked questions

Short answers, with the status stated.

Does A8 Core™ file every form itself?

It produces, delivers and files where the institution is the filer — custodian, trustee, withholding agent, broker, lender — and prepares the data where someone else files: the plan sponsor’s Form 5500, the employer’s W-2 and 1095 feeds.

Which obligations are quarterly?

Federal withholding deposits on the Form 945 schedule, Form 990-T estimated payments when an account’s expected UBTI tax reaches $500, and state withholding returns per state regime.

Where do the numbers on a form come from?

From ledger facts — contributions by type and year, distributions by code, fair market values, rollovers, conversions — through versioned rule tables. Nothing is typed. Corrections are new versions that reference the original.

What is the status of this coverage?

A product specification. The legacy platform produced Forms 5498 and 1099-R; the full registry is described as designed, and each form’s transport is named. See product status.
