Common questions
How do I get total deductions by category from my expense spreadsheet?
Upload your spreadsheet and the tool groups expenses by the category column, handles variant spellings like 'Office Supplies' and 'office supplies' as one category, and gives you a summary table with totals. It applies deduction limits where they exist — meals at 50%, vehicle by mileage — so the totals are filing-ready.
What is the fastest way to separate business and personal expenses for taxes?
The tool reads any column you use to mark personal expenses — 'Personal', 'Non-deductible', or a blank tax category — and excludes those rows from deduction totals. You get one report of business expenses and one list of what was excluded, so you can verify nothing was miscategorized.
How do I calculate quarterly income and expense totals?
The tool splits your data by calendar quarter using the date column and gives you income and expense totals for Q1 through Q4. If you need fiscal quarters or a custom date range, you set the start month and it recalculates.
What does a tax data analyzer do?
A tax data analyzer reads your expense and income spreadsheet, groups transactions by category, calculates totals with deduction limits applied, separates business from personal spending, and produces filing-ready summaries. You upload the file and get the reports without writing formulas or building pivot tables.
How do I find which expenses are missing receipts before filing?
The tool flags any expense over $75 that does not have a receipt reference in your spreadsheet, and it lists them in a separate report. You can fix or document those entries before filing instead of discovering the gap during an audit.
Try it with your own file
DataMimi reads the file you actually have — merged cells, headers below row one, totals pasted at the bottom — and shows which rows and columns every number came from.
