Your client calls at 7 PM. You’re away from the office, iPad in hand, and the QuickBooks file you need is sitting on a Windows PC back at the firm. That’s exactly the scenario RDP on iPad solves — and it takes less than 15 minutes to set up correctly.
This guide covers preparing your Windows PC, installing Microsoft Remote Desktop on your iPad (iPadOS 17 or later required), configuring the connection, and handling the edge cases that trip people up the first time.
Prepare Your Windows PC Before Touching the iPad
Skipping this step wastes time. The iPad app can’t create a connection that doesn’t exist on the Windows side.
Step 1. Open the Start menu and go to Settings → System → Remote Desktop.
Step 2. Flip the Enable Remote Desktop toggle to On. Windows will warn you about firewall rules — accept the defaults.
Step 3. Write down the PC name shown under How to connect to this PC. You’ll paste this into the iPad app. The PC name field also accepts an IP address or an Internet domain name — useful if you’re connecting over a VPN.
Step 4. Decide which user account will authenticate. You can add a dedicated user under Remote Desktop Users, or the default administrator account applies automatically. For a CPA firm, a dedicated account per staff member is cleaner from an audit-trail standpoint.
Step 5. Confirm both devices are on the same local network for a first test. If you’re connecting from outside the office — say, from a client site — you’ll need either a VPN (Tailscale and WireGuard are both well-regarded for this use case ) or proper port forwarding. Don’t skip the VPN step for a firm network; exposing RDP directly to the internet invites brute-force attacks.
Install the Microsoft Remote Desktop App on Your iPad
Microsoft Remote Desktop for iPadOS requires iOS 17 or later. Check your iPad’s software version under Settings → General → About before downloading.
Step 1. Open the Apple App Store on your iPad.
Step 2. Search for Microsoft Remote Desktop. The publisher is Microsoft Corporation. Tap Get to download and install it.
Step 3. Once installed, open the app. You land in the Connection Center — a clean list view that starts empty.
Step 4. Tap the + icon in the top-right corner, then choose Add PC.
Step 5. In the PC name field, enter one of the following:
- The Windows computer name (e.g.,
ACCOUNTING-PC) - An IP address (e.g.,
192.168.1.50) - A domain name
- Any of the above with an explicit port:
10.0.0.1:3389orMyDesktop:3389
The port notation matters if your router forwards a non-standard port for security reasons.
Step 6. Under User Account, tap Add User Account and enter credentials in one of these formats:
user_namedomainuser_nameuser_name@domain.com
Alternatively, select Ask when required — the app will prompt for credentials each session, which some firms prefer for shared iPads.
Step 7. Tap Save. The PC now appears in your Connection Center.
Connect and Handle the Certificate Prompt
Tap the PC tile to initiate the connection. The first time you connect to a PC, Microsoft Remote Desktop will show a certificate verification dialog. Tap Accept to continue. This is normal behavior for a self-signed certificate on a local Windows machine — it does not mean something is wrong.
Once connected, you have full access to the Windows desktop. On an iPad with a hardware keyboard and mouse, the experience is close to sitting at the PC directly. Without a keyboard, the app provides an on-screen toolbar for common shortcuts.
Common Connection Problems and Fixes
Can’t find the PC by name — Switch to IP address. On the Windows PC, open Command Prompt and run ipconfig to find the local IP. Note that DHCP can change this address; for a permanent setup, assign a static IP on your router.
Connection refused on the same network — Confirm the Windows Firewall isn’t blocking RDP. Go to Windows Defender Firewall → Allow an app → check Remote Desktop.
Connecting from outside the office fails — You need a VPN. Tailscale is the simplest option for a small firm: install it on both the Windows PC and the iPad, and the two devices appear on the same virtual network regardless of physical location.
App won’t install — Verify the iPad runs iPadOS 17 or later. Older iPads that can’t update past iPadOS 16 won’t run the current Microsoft Remote Desktop client.
How Sagenext Helps
Setting up and maintaining RDP works well for occasional remote access, but for a CPA firm where five or ten staff need reliable, concurrent access to QuickBooks Desktop, Drake, Lacerte, or Sage 50, managing your own RDP infrastructure adds IT overhead that eats into billable time.
Sagenext hosts your firm’s tax and accounting software on managed cloud servers. Staff connect through a remote desktop session — iPad, Mac, or PC — without anyone at the firm configuring Windows Remote Desktop, firewall rules, or VPNs. Provisioning, backups, security patches, and multi-user licensing are handled on the hosting side.
For a 10-person firm, that trade-off is usually worth it: the IT time saved per month exceeds the hosting cost, and you stop worrying about one person’s RDP misconfiguration locking everyone out during tax season.
Key Takeaways
- Enable Remote Desktop on the Windows PC under Settings → System → Remote Desktop before configuring the iPad.
- Microsoft Remote Desktop for iPadOS requires iOS 17 or later — confirm your iPad’s version first.
- The PC name field accepts a computer name, IP address, domain name, or any of these with a custom port (e.g.,
10.0.0.1:3389). - For remote access outside your office network, use a VPN such as Tailscale or WireGuard rather than exposing RDP directly to the internet.
- Accept the certificate prompt on first connection — it’s expected behavior for a local Windows machine.
- Firms with multiple staff needing concurrent access to hosted accounting software should evaluate managed cloud hosting as an alternative to self-managed RDP. QuickBooks Hosting A Practical Setup Guide For CPA Firms
Frequently Asked Questions
What iOS version does Microsoft Remote Desktop require on iPad?
Microsoft Remote Desktop for iPadOS currently requires iOS 17 or later. If your iPad can’t update to iPadOS 17, the app won’t install or run. Check your version under Settings → General → About → iPadOS Version before downloading. iPads that are hardware-limited to iPadOS 16 or earlier will need an alternative remote access solution.
Can I connect to my office PC from outside the network using RDP on iPad?
Yes, but not without additional setup. Connecting over the internet requires either a VPN — Tailscale and WireGuard are practical options for small firms — or router-level port forwarding. Direct internet exposure of RDP (port 3389) is a known security risk and not recommended for a firm handling client financial data.
How do I enter credentials in the Microsoft Remote Desktop iPad app?
When adding a PC, tap Add User Account under the User Account field. You can enter credentials as user_name, domainuser_name, or user_name@domain.com. If you prefer to be prompted each session — useful on a shared iPad — select Ask when required instead of storing credentials in the app.
Why does the app show a certificate warning when I first connect?
Windows generates a self-signed certificate for Remote Desktop connections. The first time your iPad connects to a PC, Microsoft Remote Desktop displays a dialog asking you to verify and accept that certificate. Tap Accept to proceed. This is standard behavior, not an error. On subsequent connections to the same PC, the prompt won’t reappear unless the certificate changes.
What’s the difference between using RDP on my own iPad versus a hosted cloud desktop?
Self-managed RDP gives you remote access to a specific physical Windows PC — which means that PC must stay powered on, connected, and properly configured. A managed cloud hosting environment, like Sagenext provides for QuickBooks or Lacerte, runs the software on a dedicated cloud server. Any device, including an iPad, connects to that server rather than depending on a single office PC staying online.
