Our Delaware annual total assumes the standard charter and the estimated franchise-tax minimum; actual tax can be higher. Registering or paying taxes in the state where you operate, income-tax preparation, and expediting are additional costs.
Banking is available through the Mercury × Corply partner page. Corply may receive referral compensation. Mercury decides account eligibility and approval. Bank incentives are separate from Corply’s prices and are not deducted from these totals.

FAQ
- Is Corply a Firstbase alternative?
- For a Delaware C-Corp, yes. Both form the company and file the Delaware annual report and franchise tax. Firstbase also sells bookkeeping, tax returns, and a mailroom, which Corply doesn't. Corply also forms member-managed Florida LLCs, and reminds you when Florida's annual report is due.
- Which costs less each year?
- For the registered agent and the Delaware annual filing, Corply’s service subtotal is $150/year; its total estimate is $600 or more with Delaware’s report fee and estimated tax. Firstbase Agent is $299/year per state before those same state charges. If you also want books and taxes done, Firstbase sells those and Corply doesn't.
- Which is better for founders outside the US?
- Firstbase sells a mailroom with a physical business address. Corply doesn't offer one. Firstbase includes an expedited EIN. Corply prepares the EIN application, including for founders without a Social Security number, and our team submits it.
- Do I need to be technical?
