CLUSTER TAX-MOBILE-FILING · 54 ENTRIES · EARLIEST ENTRY 2013-01-17

Tax filing and refund apps

This cluster of 46 products spans tax filing, refund estimation, tax-code lookup, and government e-payment apps across multiple countries, from consumer-facing return prep to official issuance. Entries trace back to 2011 and appear on a mostly steady, low-frequency cadence (typically 1-2 per month) until just before the index start, without any single period showing a dominant cluster. Traction leaders are notaflow, Tax Asaan, and Asset Recovery: Tax Refund, each with 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
