Tax-prep organization, not tax advice

Tax-Prep Document Source Map: Where Each File Comes From

Gathering tax documents stalls on one question, repeated dozens of times: "Where does this come from again?" You know you need a year-end statement, but is it in the bank portal, mailed by a brokerage, or issued by a platform you logged into once last spring? A source map answers that question once and keeps the answer. It is a plain reference that pairs each expected document with its origin, the specific account, platform, payer, or party that issues it, plus where to go and which login to use. Cash Workspace lets you build this map as a record set with the actual source documents attached as they arrive, so the map and the files live in one place. This page is organizational guidance for assembling your own document set, not tax advice; it does not tell you which documents your situation requires or how to file. It maps where things come from so the fetching is fast.

The problem

Why "where does this come from?" wastes the most time

The slow part of tax prep is rarely filing the documents you already hold. It is the hunting, retracing which portal a statement lives in, which email address a platform sends to, which family member holds the original. A source map removes that friction by recording the origin of each expected document before you start fetching, so the gathering pass becomes a checklist of known destinations instead of a memory test. It deliberately stops at origin: it does not tell you whether each item has arrived yet (that readiness view is a separate record), and it does not log your open questions about a document. It answers one thing well, where to go to get each file.

  • You remember you need a year-end summary but not whether it comes from the bank portal, a mailed envelope, or a platform dashboard you rarely open.
  • Logins are scattered: some documents sit behind a personal account, others behind a business account, and you waste time guessing which one issues which file.
  • Some documents are not in any portal at all, they come from a person or party (a former employer, a property manager, a co-owner) and need a request.
  • Each year you re-derive the same origins from scratch because last year's hunt left no written trail.
  • A document arrives but you cannot remember which source it satisfied, so you re-check sources you have already cleared.

Build the map

Building your document source map in Cash Workspace

The goal is a stable reference you build once and refine each year. Create one record per expected document, fill in its origin fields, and attach the real file to that same record once you fetch it, so the map doubles as the home for the document it points to. Cash Workspace does not connect to any source or pull documents for you; every file is uploaded by hand. The map simply tells you where to go.

  1. 1

    Create a Document Sources folder inside the year's tax-prep folder

    Inside Tax Prep 2025, add a folder named Document Sources. This is where the source map lives, separate from the folders that hold sorted, finished documents. Keeping the map in its own folder means the where-to-fetch reference stays distinct from the gathered set.

  2. 2

    Add one record per expected document

    Make a record for each document you expect, named for the document itself, for example Year-End Bank Interest Summary, Brokerage Year-End Statement, or Mortgage Interest Statement. Name the document, not the source, so the map reads as a list of things to collect.

  3. 3

    Fill in the origin fields on each record

    For every record, record the source/issuer, the source type (online account, mailed, person/party, in-platform), where to fetch it (portal name plus URL or the mailing it arrives in), and which login identity to use. This is the heart of the map, the answer to where does this come from.

  4. 4

    Note how each source delivers it

    Add a delivery method note: downloaded from a dashboard, emailed to a specific address, mailed to a home address, or handed over by a person. For person/party sources, note who to ask and how, so a request can go out early.

  5. 5

    Attach the real document when you fetch it

    When you retrieve a file, attach it to its source record. The map record then holds both the origin reference and the actual document, so next year you can see exactly where last year's copy came from. Note that whether an item is still outstanding belongs on your readiness tracker, not here.

  6. 6

    Save the finished map as a reusable reference

    Once a record set is built, copy it forward each year and update only what changed, a new platform, a closed account, a different login. The map becomes a standing reference that gets faster every year instead of being rebuilt from memory.

Record structure

Fields to record per expected document

These are the metadata fields that make a source map useful. They describe origin and retrieval only, not status and not content. Record them once per expected document.

Document name
What the document is, in plain words, for example Year-End Savings Interest Summary or Property Management Annual Statement. This is the record title and what you are trying to fetch.
Source / issuer
The specific account, platform, payer, or party that produces the document, for example First Northwest Bank, Maple Street Brokerage, or your property manager Dana Ruiz.
Source type
Online account, mailed, in-platform dashboard, or person/party. This tells you at a glance whether to log in, watch the mailbox, or send a request.
Where to fetch / location
The portal name plus URL, the section of the dashboard, or the mailing it arrives in, the precise place you go to retrieve it.
Login identity to use
Which account or email the source is tied to, for example the business account vs a personal account, so you do not waste time logging into the wrong one.
Delivery method
How the source hands it over: downloaded, emailed to a named address, mailed to an address, or given by a person. Person/party sources note who to ask and how.
Notes for next year
A short reference note, account closed, new platform replaced the old one, this source mails late, so the map improves year over year.

Example setup

An example source map layout

Here is how a Document Sources folder might look for a self-filer with a small side business. Each record names a document and carries its origin fields; the real file is attached to its record once fetched. This is illustrative structure, not a list of which documents anyone is required to gather.

Common mistakes

Common mistakes when mapping document sources

  • Naming records after the source instead of the document, which turns the map into a list of accounts rather than a list of files to gather.
  • Mixing in readiness status (gathered vs missing) and treating the map as a checklist, that present-vs-missing job belongs on the progress tracker, not here.
  • Leaving the login identity blank, so each year you guess whether a document sits behind the personal or the business account.
  • Forgetting person/party sources entirely because they are not in any portal, then scrambling late to request them.
  • Recording only the platform name without the exact location or URL, so you still have to dig for the right tab when you fetch.
  • Rebuilding the whole map from memory each year instead of copying last year's record set forward and updating only what changed.

How it helps

How Cash Workspace supports a source map

One record per expected document

Create a record for each document you expect, hold its origin fields in one place, and keep the whole map inside a Document Sources folder within the year's tax-prep folder.

Attach the real file to its source record

When you fetch a document, attach it to the record that maps its origin, so the map and the actual file live together and next year's hunt is instant.

Fiscal-year folders and reuse

Keep a Document Sources folder per tax year and copy the record set forward each year, updating only the sources that changed. The map gets faster, not slower, over time.

No automation, by design

Cash Workspace does not sync with your bank, log in to platforms, or pull documents. It does not read your files or extract data. You fetch each document from its source; the map just tells you where that source is. It is free.

FAQ

Frequently asked questions

What exactly is a document source map?
It is a reference that pairs each expected tax document with its origin, the specific account, platform, payer, or party it comes from, plus where to fetch it and which login to use. Its single job is to answer where does this come from so the gathering phase is fast. It does not track whether items have arrived yet; that readiness view belongs on the progress tracker.
Does Cash Workspace fetch or download my documents automatically?
No. Cash Workspace does not sync with banks, log in to platforms, or pull any document. It does not read or extract data from your files. You retrieve each document from its source by hand and attach it to the matching record. The map only records where each source is so you can go there quickly.
Is this tax advice, does it tell me which documents I need?
No. This is organizational guidance for assembling your own document set, not tax advice. It does not tell you which documents your situation requires, how to file, or what anything means for your return. You decide what to list as expected; the map records where each one comes from.
How is this different from a progress tracker or a payee list?
The source map records origin, where to fetch each document. A progress tracker records readiness, gathered versus missing. A payee or contractor-records list catalogs people you paid. The map is distinct because it maps document origins rather than tracking status or listing payees.

Organizational guidance, not tax advice

Cash Workspace helps you organize where your tax documents come from and attach the files once you fetch them. It is not tax, legal, or accounting advice, and it does not tell you which documents your situation requires or how to file. It does not connect to your bank, log in to any platform, or download documents for you, and it does not read or extract data from your files. Every document is fetched and uploaded by you. For guidance on what your filing requires, consult a qualified professional.
