Income Rules in Ace Budget: Split Every Paycheck

If you have ever stared at a fresh deposit and thought "some of this is rent, some of this is the car thing, some of this is groceries" and then assigned it all by hand anyway, income rules in Ace Budget are for you. An income rule splits each paycheck the moment it arrives, so the money lands where you already decided it should go.

This is a small piece of automation, not a personality transplant for your budget. It saves you the ten minutes of clicking that often turns into three days of not clicking.

What income rules in Ace Budget actually do

A rule watches for deposits and sends a slice of each one to a category. The slice can be a percentage of the deposit or a fixed dollar amount, and one rule can feed one or more categories.

You can also limit a rule to deposits whose payee contains a word you choose — "Payroll", say, or part of your employer's name. That matters if more than one kind of money lands in the same account: a refund, a transfer from a friend, or your partner's paycheck shouldn't get chopped up by your rule.

Two guardrails worth knowing up front. Rules never hand out more than the deposit itself, so a $1,900 paycheck can never fund $2,100 of categories. And rules only ever touch deposits — spending is handled by auto-categorization rules, which are a separate thing.

Whatever your rules don't claim stays in Ready to Assign, where you assign it by hand. That's a feature. You want a little daylight between "automatic" and "unsupervised."

Before you write a rule, decide what each paycheck owes

Don't start in the app. Start with a short list of what one paycheck is responsible for.

Say your take-home pay is $2,100 twice a month. Rent is $1,400 a month, so each paycheck carries $700 of it. Groceries are $600 a month, so $300 each. Car insurance is $720 every six months, so $60 each. Keep going until you've covered the bills that can't be missed.

If you already use the paycheck planner, use it here — it shows which bills land before your next paycheck and how much to set aside, built from a conservative baseline of your leanest recent months. That number is a good sanity check on the list you just made.

The point is that income rules automate a decision. They don't make the decision. If your paycheck already can't cover the list, a rule will just move the shortfall around faster.

How to set up income rules in Ace Budget, step by step

1. Make sure the categories exist first. A rule needs somewhere to send money. Create or confirm the handful of categories from your list — rent, groceries, the car fund, whatever yours are.
2. Open income rules in Ace Budget and add your first one. Start with the bill that would hurt most if it bounced. Rent, usually.
3. Choose percentage or fixed amount. For a steady salary, a fixed amount is easier to reason about. For commission, tips, or freelance work, percentages hold up better.
4. Add a payee filter if other money shares the account. Enter a word that shows up in your paycheck's payee, like "Payroll", so the rule ignores everything else.
5. Add the rest of the rules in order of importance. Housing, then utilities, then food, then the savings you'd be sad to skip. The order you create them in is also the order you'd want to pause them in if income drops.
6. Wait for the next real paycheck and check the result. Look at the categories the rule funded and look at what's left in Ready to Assign. Adjust the amounts once, then leave them alone for a cycle.

If your accounts are linked through Plaid, the deposit shows up when the bank sends it. "Check for new transactions" collects whatever Plaid has already received, and it always tells you what it found, but it can't make your bank report the deposit any sooner. Payday morning impatience is normal; the rule will fire when the transaction lands.

What happens when a paycheck is short

This is where automation earns or loses your trust, so it's worth being clear.

If you wrote fixed-amount rules totaling $1,800 and the deposit is $1,500 — a short week, an unpaid day, a changed withholding — the rules cannot overdraw the deposit. Something gets less than you planned. Go look at which categories came up light and decide, consciously, where the gap lands.

Percentages behave differently: everything shrinks proportionally. That's gentler for variable income and less precise for fixed bills. Many people end up mixing the two — fixed amounts for rent and insurance, percentages for the flexible stuff.

Two other habits help here. Targets will re-pace the required monthly amount automatically when a month falls short, so a savings goal with a due date recovers without you redoing the math. And per-category carryover, if you turn it on for a category, lets overspending follow you into next month so you're paying it back instead of pretending it didn't happen.

Keeping your rules honest over time

Income rules drift the same way budgets do — quietly, after a raise or a move.

Revisit them when the paycheck amount changes, when a bill changes, or when you notice Ready to Assign is routinely much bigger or much smaller than you expected. If life gets uncertain, pause rules rather than deleting them; a paused rule keeps its settings and simply stops splitting, sending that money to Ready to Assign until you turn it back on.

In a shared budget, write a rule for each person's paycheck and use the payee filter so they don't collide. Both of you see the same rules, which is usually the point — it's one fewer conversation about who was supposed to move money for the water bill.

The honest trade-off: income rules make payday boring. You'll still want to look, because a rule that fires on the wrong deposit or an amount you forgot to update is easy to miss when nothing looks broken. Five minutes after each paycheck is enough.
