Compare
Monarch Plus is good. Here is what its own documentation says it does not do.
Monarch Plus launched on 20 April 2026 with business tracking for pass-through owners and a Business Tax Prep report that maps categories to real Schedule C lines. That is better than a summary makes it sound, and it is the right comparison. The table is the list of specific absences in Monarch’s own pages, on a date.
| Capability | Monarch Plus | Contha |
|---|---|---|
| Personal net worth, budgets, goals | Yes | Yes, every account, personal and business |
| Budgets | Yes | Yes, fixed or flexible per category, with rollover, and what is left to spend this month |
| Recurring bills and subscriptions | Yes | Yes, with what is due in the next 30 days on the overview |
| Investments | Yes | Yes, holdings with cost basis and gain |
| Business income and expenses beside the personal books | Yes, on Plus | Yes, personal and business on every row, with splits |
| Schedule C, Parts I and II | Yes, with user-customisable line mapping | Yes, by line; one per sole proprietorship |
| Self-employment tax | Not listed in its business features | Yes, on 92.35% of net profit, the wage base less W-2 wages |
| Quarterly estimated tax | Not listed in its business features | Yes, computed: four payments as a schedule, past due and next |
| Mileage, home office | Not listed in its business features | Yes, Pub. 463 substantiation per trip |
| S-corp and C-corp | "Not yet optimized" | Not yet; one sole proprietorship or single-member LLC today |
| Partnership, fractional ownership, K-1 position | Not supported | Not yet |
| Contractors and 1099-NEC | Not listed in its business features | Yes, payees on line 11, the $2,000 threshold for 2026, W-9 marks; no e-file |
| Accountant handoff | PDF or CSV export | Yes, five files and a read-only link that needs no account |
| A spouse with their own login | Yes | Yes, a spouse with their own login, editor or viewer |
| Honest about dead feeds | Status per connection | Every figure says which feeds are behind; one email when a feed dies |
| Price | Core and Plus; its pricing page lists $99.99 a year ($8.33 a month) or $14.99 a month and does not say which tier each is, and gives no separate Plus price | A free week, then Personal $5, Business $10 a month; two months free on annual billing |

The honest read
Monarch comes at this from the personal side. Contha comes from the return.
If you are a W-2 household with a side business that files one Schedule C, Monarch Plus covers Parts I and II and you should consider it. If you want the number to set aside rather than a worksheet, and whether that money is actually there, that is what this was built for. What you give up by moving: Personal keeps 5 banks connected (Business 10; anything else imports as a CSV each month), and Contha is a web app you add to your home screen, not an App Store app. Your Monarch history comes with you: its transaction export imports with categories and tags.
Also against QuickBooks Solopreneur, Found, Keeper, Copilot Money, YNAB, Wave, Tiller, Collective, Lili, Hurdlr, FreshBooks.
Keep Monarch if it is enough. If the tax is the reason you are here, start with Contha.
Free with one bank, no card. Personal $5 or Business $10 a month for the rest, a free week of either first. Read-only connections, cancel any time.
