If wave could pipeline directly to H&R block for automated tax filings it could be a really nice experience. Can't expect too much though, I just hope they don't kill it.
We already have automated tax filings in the US, the IRS does them first and those are what they use to check what you file to them. H&R Block et all lobbies to force the US tax payers to not have automatic filing.
Wave is for small businesses or consultants. The government doesn’t know about most of the things that happen at low levels until the business reports it. End of the year bookkeeping can be a nightmare.
