02 — How it works
Progressive slabs are computed band-by-band, so the PDF shows exactly which slab contributed what. Switch regimes mid-flow to compare old vs new in one sitting.
India new/old, US Federal, UK, or build your own custom slabs. Standard deduction, cess, and tax-ID label adapt automatically.
Each income source as a line; deductions with optional section tags (80C, 80D…). Standard deduction is pre-filled per regime.
PDF showing every slab's contribution to tax, cess, surcharge, effective and marginal rates — plus a matching .xlsx for your records.
03 — Built for tax workings
India new + old (FY 2025-26), US Federal (2025), UK (2025-26), plus custom slabs for any country.
Each band shown with its rate, taxable amount in that band, and the tax contribution.
India 4% health & education cess auto-applied. Surcharge editable for high-income brackets.
Effective rate = total tax ÷ gross income. Marginal rate = the band you're currently in.
Build your own slabs — band thresholds and rates editable. Useful for hypotheticals and policy modelling.
Each deduction line carries a section tag (80C, 80D, NPS) — printed alongside the description in the PDF.
Bulk OCR, batch invoicing, multi-party e-signing, redaction, audit logs — pdfFiller picks up where Sonchoy ends. Free for 30 days, no credit card.
Run 100+ invoices, statements, or conversions in one go.
Turn paper invoices into searchable, exportable data.
Multi-party signatures with full audit trails.
Mask sensitive ledger lines before sending to auditors.
04 — Common questions
It produces a clean working sheet — the format a CA or tax preparer would normally type up by hand. Use it to prepare for filing, not to file. Verify against the latest official notifications before submitting any return.
Income is sliced across bands. The tax for each band = (income within that band) × (band rate). The total is the sum across all bands. The PDF shows each band as a separate row so the math is auditable.
Effective rate = total tax ÷ gross income (your actual tax burden as a %). Marginal rate = the rate that applies to the next rupee/dollar of income (the top slab you're in). Marginal is usually higher than effective.
Generate the sheet under each regime in turn. Old regime allows 80C, 80D, HRA and home-loan deductions but has higher slab rates; new regime has lower rates but very few deductions. The "cheaper" regime depends on your deduction profile.
India: 4% health & education cess applied on tax automatically. Surcharge is user-editable (typical 10%, 15%, 25%, 37% depending on income) — type the rate per your taxable income bracket.
PDF (working sheet with slab breakdown, key metrics, regime note) and .xlsx (every line item plus the slab table — easy to drop into a CA's working file).
