Who has to register and when
The VAT Act 2013 requires a person making taxable supplies to register when those supplies reach KES 5 million within any twelve-month period, or are expected to. The test looks at taxable supplies, not profit, so a business with thin margins can still cross the line. Exempt supplies and some other categories are treated differently.
Do not wait for the end of the calendar year. Work out your rolling twelve-month taxable turnover every month from your invoice records, because liability starts from the date you should have registered, and KRA can assess VAT for that gap even if you never charged customers.
Voluntary registration below the threshold is permitted. It makes sense when your customers are VAT-registered businesses that can reclaim input tax, and when you buy a lot of VAT-bearing inputs. It makes less sense when you sell mainly to consumers who cannot reclaim VAT and would feel the price rise.
Practical example: a consultancy bills KES 400,000 a month for eleven months and then lands a large contract in month twelve, taking the rolling total past KES 5 million. The obligation arises when the threshold is reached or expected, not at the next financial year end, so registration should be started as soon as the large contract is signed.
Registering through iTax
Registration is made on iTax by adding the VAT obligation to an existing KRA PIN, supported by the details of the business, the principal activity, premises and contacts. KRA may verify the information and, in some cases, visit the premises, so make sure the address you give is real and reachable.
Once the registration is approved you receive a VAT certificate and your PIN profile shows the VAT obligation with a monthly filing cycle. From that date, enrol on eTIMS before issuing tax invoices so that your invoices are valid for your customers' own input VAT claims.
Record the effective date of registration carefully. Supplies before that date follow the old rules, and supplies after it carry VAT where taxable. A wrong effective date on your records leads to under- or over-charged invoices that are tedious to correct.
Prepare the supporting documents before you open the application: the incorporation certificate or business name certificate, the lease or proof of premises, identification of the directors and a description of your products. A complete application avoids requests for additional information that restart the clock.
Rates, zero-rating and exemption
The standard rate is 16 %. Some supplies are zero-rated, which means VAT is charged at 0 % and the supplier can still reclaim input tax; exports of goods are the best-known example. Other supplies are exempt, where no VAT is charged but the supplier cannot reclaim related input tax. The two treatments are not interchangeable.
The schedules of the VAT Act and later finance legislation move items between the categories, so never copy a classification from a supplier or a competitor. When in doubt about a product or service, ask KRA in writing or consult your tax adviser and keep the answer in your file.
On an invoice, show the VAT-exclusive price, the VAT amount and the total, along with your PIN and the customer's PIN where required. Mixed invoices that combine standard-rated, zero-rated and exempt lines need each line labelled clearly or the return will not reconcile.
Be careful with price lists. A business that quoted VAT-inclusive prices to consumers before registration must decide whether to absorb the 16 % or raise prices, and contracts with fixed prices signed before registration may need a clause on tax changes. Check existing agreements so that you do not end up funding VAT from your own margin without having intended to.
Returns, payments and input VAT
VAT returns are filed monthly on iTax, and payment is due by the deadline set in the VAT Act, which falls in the month after the tax period. Late filing and late payment each attract penalties and interest, and a nil return is still a return that must be filed.
Input VAT can be claimed only on purchases supported by valid tax invoices that carry your PIN and business name and relate to taxable activity. Invoices without your PIN or issued to a different name do not count, so ask suppliers to get the buyer details right at the time of sale.
Reconcile the return with your records every month: total sales by category, VAT charged, purchases with VAT, and the net position. Where input exceeds output, the credit is carried forward or claimed as a refund under KRA's refund rules, which require supporting documents and can take time.
Cancellation is also possible. If turnover falls well below the threshold or you stop trading, apply on iTax to deregister, settle outstanding returns and account for VAT on remaining stock and assets as KRA requires. Simply ceasing to file leaves the registration alive and the penalties running.
What the 4b2b modules do here
4invoices.net creates PDF invoices with the VAT rate you enter and archives them. It does not decide whether a supply is taxable, zero-rated or exempt, and it does not transmit anything to KRA, so eTIMS enrolment and the VAT return stay with you and your accountant.
Use the invoice archive as one source when assembling the sales side of your return, and keep purchase invoices in a separate, labelled folder. 4softerp.net can hold multi-company financial records if you run more than one entity, but it does not file on iTax.
Before registering, ask your accountant to model the price impact on your customers and the cash-flow effect of paying output VAT before you collect from slow payers. That conversation is more valuable than any software setting.
