What Tax Deduction Tracker does, with a checked example

A running log for deductible expenses: enter each purchase's date, amount, and a category chosen from a list built around Schedule C business-expense lines (or Schedule A for itemized personal deductions), and the tracker keeps a per-category subtotal plus a year-to-date total. What people get wrong most often is treating the category list as an eligibility test - the tool sorts and sums what you type in, it does not judge whether a given expense actually qualifies as deductible under current IRS rules.

Worked example

A concrete input and expected output from the current implementation.

Input

Office Supplies: $89.50 (3/5), $34.25 (3/18); Software Subscriptions: $59.99 (4/2)

Expected output

Office Supplies subtotal: $123.75. Software Subscriptions subtotal: $59.99. Year-to-date total: $183.74.

The tracker sums entries within each category (89.50 + 34.25 = 123.75) and adds all category subtotals for the running total (123.75 + 59.99 = 183.74).

How the result is produced

1

Category subtotals

Each entry gets a date, amount, and a category picked from a preset list modeled on Schedule C expense lines (supplies, vehicle, insurance, office expense) or Schedule A categories (medical, charitable, taxes paid). As you add entries the tracker keeps a running subtotal per category and a combined year-to-date total across all categories.

2

Receipt logging

The tool's own description lists receipt logging alongside the category summaries, so each expense entry appears to support attaching some form of receipt reference in addition to date, amount, and category. The exact fields that entry form captures - and how records are stored between sessions - aren't specified here, so check the tool directly before relying on it as your sole record.

Good uses

  • a freelancer or self-employed person logging business expenses through the year to hand category totals to their preparer for Schedule C
  • someone tracking itemizable costs like charitable gifts or medical bills as they occur, instead of reconstructing them in April for Schedule A
  • a small business owner who wants running category subtotals to sanity-check against receipts before a bookkeeper closes the books

Limits and checks

  • the category labels approximate Schedule C and Schedule A groupings but are not a substitute for the current IRS instructions - line numbers and thresholds change year to year and this tool does not track that
  • it totals what you enter but does not evaluate deductibility - mixed personal/business use, home-office percentages, and similar limits are judgment calls you still have to make
  • how the tool stores and retains your entries between visits is not specified here - confirm that behavior directly in the tool rather than assuming any particular storage or backup arrangement

Common questions

does this file anything with the IRS or send data anywhere?

No. It only logs and totals expenses locally; nothing is transmitted or filed. You take the category totals it produces and enter them yourself into tax software or give them to a preparer.

can I upload photos of my receipts into it?

The tool's description mentions receipt logging as a feature but doesn't specify whether that means attaching image uploads, a text reference, or something else - check the entry form in the tool itself to see which it supports, and keep your actual receipt images or paper copies filed separately either way.
