A tax change is announced, the news cycle moves on and months later a business discovers it has been applying an old rate. The change did not hit with a bang; it hit through payroll, invoices and prices that nobody had updated. Treat each change as a small project with a checklist, and you will absorb it without drama. This guide gives you one.

Step 1: Understand what changed

Before you review anything, be clear on the facts. Which tax is affected? What exactly changes: the rate, the threshold, the base, the deadline or the procedure? From what date? Find the official wording or a reliable summary, and write the change in one sentence. If you cannot explain it simply, you are not ready to act.

Step 2: Decide who it affects

Not every change affects everyone. A change to PAYE bands matters to employees and employers; a change to VAT affects registered businesses and their customers; one to rental income tax affects landlords. List the people and activities in your life or business that fall under the rule. If it affects nothing you do, note that and move on.

Step 3: Review payroll

If the change touches pay, tax or statutory deductions, rerun your payroll. Compare a sample of payslips under the old and new rules and check that the system applies the right figures from the right month. The PAYE calculator and the net to gross salary calculator let you test examples, and how to run payroll for a small business explains the process. Tell employees what has changed and why their take-home pay moved.

Step 4: Review pricing and invoices

If a tax on sales or inputs changes, your margins change. Recalculate the price of each product and service. Check the VAT shown on invoices, the descriptions and the format. The VAT calculator separates tax from price, and VAT invoices and quotations lists what an invoice must show. Update your quotations and price lists from the effective date.

Step 5: Review contracts

Look at long-running contracts: rent agreements, supply contracts, service agreements and employment contracts. Do they say whether prices include tax? Who bears the cost of a change in tax? If the contract is silent, discuss it with the other party before the date rather than after. How tax changes affect your contracts and prices goes into this in more detail.

Step 6: Review cash flow and budgets

A change in what you pay or collect changes your cash. Update your forecast for the new amounts and the new dates, and see whether the lowest cash balance still works. Cash flow forecast for a small business shows the method, and budgeting for a small business helps you adjust the plan. Employees can revisit their personal budget with how to budget on a Kenyan salary after deductions.

Step 7: Review your filing calendar

Deadlines sometimes change with tax rules, and new returns may appear. Update your calendar and set reminders. The KRA filing and payment calendar lists the dates in one place, and the KRA filing calendar for small businesses explains them.

Step 8: Review your records

Make sure your records capture what the new rule requires. If you must now report something separately, add a column. If a new document is required, set up a place to keep it. The change may also affect which expenses are deductible; check expenses small businesses can deduct.

Step 9: Tell the people who need to know

Employees, customers, tenants and your accountant should hear about the change from you, with the date and the effect. Silence leads to complaints and mistakes. A short note is enough.

Step 10: Check back later

After the first month or quarter under the new rule, check the results. Did the payroll come out right? Were invoices accepted? Are margins what you expected? Fix any gaps and record what you learned. A quick review now prevents a penalty later.

Keep a change log

Write each change in a log with the date, the effect and what you did. After a few years you will have a record of how the rules moved and how your business responded. That log also helps a new accountant or employee understand why things are done the way they are.
