Release 22 of PayTrove came out in September 2026. It covers the owner's twelve priority items and the pointers from a code review. Existing companies keep their figures on upgrade: employees stay monthly, runs become monthly runs, there are no extra reliefs until you record them, the single development levy stays, no receipt file is required and no payslip emails are sent until you switch them on. Deadline alerts are on, but send nothing until email is set up.
| What changed | In short | Where in this guide |
|---|---|---|
| Faster runs | Each kind of record is read once per run and the lines are saved in one batch: a 2,000-employee run takes about 23 database statements to create and 32 to approve, so large payrolls no longer fail. | Chapter 15 |
| Approval in one step, with Repair | Approval writes the obligations, loan and order balances, audit entry and status together or not at all; a run left 'approving' can be finished or returned to draft; Repair fixes older runs missing their obligations. | Steps 15.2–15.3 |
| Calculation errors and notes | A failed lookup stops the run with a clear message; errors (₦0 or 0% orders, bad months or figures, schedule staff with no pay per period) block approval with no override; notes flag unclaimed reliefs, arrears and loans without instalments. | Steps 6.2, 15.1 |
| NTA 2025 s.30 reliefs | Health insurance (NHIS/NHIA), life assurance or annuity premiums and mortgage interest on an owner-occupied home, each with evidence, in PAYE, on the payslip and on the annual return. | Chapter 12 |
| Form H1 changes | Employer 13-digit Tax ID; employee Tax IDs flagged; relief columns including rent relief; the earlier employer; the LIRS eTax layout, generic and custom layouts per state; the schedule of payments to vendors and consultants. | Chapter 20, step 2.1 |
| Dated rate sets | The minimum wage, bands and statutory rates are dated rule sets read by pay date; TroveUniverse staff add national changes, companies may raise pension rates and set their levy. | Chapter 21 |
| Earlier-employer pay for mid-year joiners | Recorded from the leaver statement so the tax-free band and reliefs are given once; the earlier PAYE is never refunded by the new employer. | Steps 12.5–12.7 |
| Bank files and paid-versus-run | NIBSS bulk file with bank codes, bank starting layouts and custom layouts; account checks with the bank; importing the bank's response; the re-pay file. | Chapter 14, step 6.13 |
| Remittance receipts and statements | Optionally require the government receipt itself before a remittance is recorded; each employee's statutory deductions statement with remittance status, in self-service and as a PDF. | Steps 7.9–7.11, 18.4 |
| Weekly and fortnightly pay | Pay schedules with their own runs; PAYE cumulative in weeks or fortnights; payslips show the frequency. | Chapter 13 |
| Payslip and deadline emails, invitations | Payslip notices with a secure link and no figures; a daily deadline digest; users invited by email to choose their own password. | Chapter 16, steps 3.2–3.3 |
| Ledger mapping and Send to BookTrove | Map each payroll element to an account code; the CSV journal uses the codes; approved runs are sent to BookTrove with their status and entry number. | Chapter 17 |
| Development levy by state | Each employee's state of residence decides the levy, from a table seeded at the Act's ₦100 ceiling, when switched on. | Steps 21.5–21.6 |
